From 7ebe49b76a001b10b007193b1771f33e6cbc4f3f Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Sun, 16 Oct 2022 12:41:26 +0200 Subject: [PATCH 0001/1098] driver core: allow kobj_to_dev() to take a const pointer If a const * to a kobject is passed to kobj_to_dev(), we want to return back a const * to a device as the driver core shouldn't be modifying a constant structure. But when dealing with container_of() the pointer const attribute is cast away, so we need to manually handle this by determining the type of the pointer passed in to know the type of the pointer to pass out. Luckily _Generic can do this type of magic, and as the kernel now supports C11 it is availble to us to handle this type of build-time type detection. Cc: "Rafael J.

During this check the dentry inode i_lock is taken to mitigate against a possible concurrent rename.

After wakeup, it's no longer possible to control the led. It turned out that the register settings to enable or disable the led were not correct. They worked for some dongles like the Edimax V2 but not for others like the InterTech DMG-02. This patch fixes the register settings. Bit 3 in the led_cfg2 register controls the led status, bit 5 must always be set to be able to control the led, bit 6 has no influence on the led. Setting the mac_pinmux_cfg register is not necessary. These settings were tested with Edimax V2 and InterTech DMG-02.

The userspace would have to parse the configfs to know which interface index it has to compare the ctrl requests against. Since the interface numbers are not fixed, e.g. for composite gadgets, the interface offset depends on the setup. The kernel has this information when handing over the ctrl request to the userspace. This patch removes the offset from the interface numbers and expose the default interface defines in the uapi g_uvc.h.

How to do that with CPPI? - * - * - RX queues in "rndis" mode -- one single BD -- handle (a) correctly, but - * (b) loses **BADLY** because nothing (!) happens when that second packet - * fills the buffer, much less when a third one arrives. (Which makes this - * not a "true" RNDIS mode. In the RNDIS protocol short-packet termination - * is optional, and it's fine if peripherals -- not hosts! -- pad messages - * out to end-of-buffer. Standard PCI host controller DMA descriptors - * implement that mode by default ... which is no accident.) - * - * - RX queues in "transparent" mode -- two BDs with 512 bytes each -- have - * converse problems: (b) is handled right, but (a) loses badly. CPPI RX - * ignores SOP/EOP markings and processes both of those BDs; so both packets - * are loaded into the buffer (with a 212 byte gap between them), and the next - * buffer queued will NOT get its 300 bytes of data.

charset=UTF-8 Content-Transfer-Encoding: 8bit Returning an error value in a platform driver's remove callback results in a generic error message being emitted by the driver core, but otherwise it doesn't make a difference. The device goes away anyhow. For each case where ret is non-zero the driver already emits an error message, so suppress the generic error message by returning zero unconditionally. (Side note: The return value handling was unreliable anyhow as the value returned by dwc2_exit_hibernation() was overwritten anyhow if hsotg->in_ppd was non-zero.)

Instead, introduce a const version of the dev_fwnode() API which takes and returns const pointers and use it where it's applicable. With this, convert dev_fwnode() to be a macro wrapper on top of const and non-const APIs that chooses one based on the type.

If it fails, the kset.kobj.name allocated by kobject_set_name() which must be called before a call to kset_register() may be leaked, since refcount of kobj was set in kset_init(). To mitigate this, we free the name in kset_register() when an error is encountered, i.e. when kset_register() returns an error. A kset may be embedded in a larger structure which may be dynamically allocated in callers, it needs to be freed in ktype.release() or error path in callers, in this case, we can not call kset_put() in kset_register(), or it will cause double free, so just call kfree_const() to free the name and set it to NULL to avoid accessing bad pointer in callers. With this fix, the callers don't need care about freeing the name and may call kset_put() if kset_register() fails.

For example, when booting with maxcpus=n, ETM probing will fail on CPUs >n, and the probing won't be reattempted once the CPUs come online. This will leave those CPUs unable to make use of ETM. This change adds a mechanism to delay the probing if the corresponding CPU is offline, and to try it again when the CPU comes online.

Prior attempts to provide a mechanism to disable this have devolved into discussions around creating full-blown LSMs to provide arbitrary ioctl filtering, which is hugely over-engineered -- only TIOCSTI is being used this way. 3 years ago OpenBSD entirely removed TIOCSTI[2], Android has had it filtered for longer[3], and the tools that had historically used TIOCSTI either do not need it, are not commonly built with it, or have had its use removed. Provide a simple CONFIG and global sysctl to disable this for the system builders who have wanted this functionality for literally decades now, much like the ldisc_autoload CONFIG and sysctl.

So unify the above into two helpers: * uart_port_tx_limited() -- it performs the above taking the written characters limit into account, and * uart_port_tx() -- the same as above, except it only checks the HW readiness, not the characters limit. The HW specific operations (as stated as "differences" above) are passed as arguments to the macros. They are: * tx_ready -- returns true if HW can accept more data. * put_char -- write a character to the device. * tx_done -- when the write loop is done, perform arbitrary action before potential invocation of ops->stop_tx() happens. Note that the above are macros. This means the code is generated in place and the above 3 arguments are "inlined". I.e. no added penalty by generating call instructions for every single character. Nor any indirect calls. (As in some previous versions of this patchset.)

charset=UTF-8 Content-Transfer-Encoding: 8bit uart_port_tx_limited() is a new helper to send characters to the device. Use it in these drivers. mux.c also needs to define tx_done(). But I'm not sure if the driver really wants to wait for all the characters to dismiss from the HW fifo at this code point. Hence I marked this as FIXME.

This behavior relies on hardware differences: most boards (if not all) with those SoCs have 12 or 24 MHz oscillators but many peripherals want 12Mhz to operate properly (AIC and USB-PHY at least). The 16MHz threshold looks arbitrary but used in vendor's bootloader code for enable the divider. The patch doesn't affect JZ4760's behavior as it is subject for another patchset with re-classification of all supported ingenic UARTs.

This driver does not handle such case properly. Currently, when a pin is multiplexed as a UART CTS_B on boot, this pin is pulled HIGH by the i.MX UART CTS circuit, which activates DE signal on the RS485 transceiver and thus behave as if the RS485 was transmitting data, so the system blocks the RS485 bus when it starts and until user application takes over. This behavior is not OK. The problem consists of two separate parts. First, the i.MX UART IP requires UCR1 UARTEN and UCR2 RXEN to be set for UCR2 CTSC and CTS bits to have any effect. The UCR2 CTSC bit permits the driver to set CTS (RTS_B or RS485 DE signal) to either level sychronous to the internal UART IP clock. Compared to other options, like GPIO CTS control, this has the benefit of being synchronous to the UART IP clock and thus without glitches or bus delays. The reason for the CTS design is likely because when the Receiver is disabled, the UART IP can never indicate that it is ready to receive data by assering CTS signal, so the CTS is always pulled HIGH by default. When the port is closed by user space, imx_uart_stop_rx() clears UCR2 RXEN bit, and imx_uart_shutdown() clears UCR1 UARTEN bit. This disables UART Receiver and UART itself, and forces CTS signal HIGH, which leads to the RS485 bus being blocked because RS485 DE is incorrectly active. The proposed solution for this problem is to keep the Receiver running even after the port is closed, but in loopback mode. This disconnects the RX FIFO input from the RXD external signal, and since UCR2 TXEN is cleared, the UART Transmitter is disabled, so nothing can feed data in the RX FIFO. Because the Receiver is still enabled, the UCR2 CTSC and CTS bits still have effect and the CTS (RS485 DE) control is retained. Note that in case of RS485 DE signal active low, there is no problem and no special handling is necessary. The CTS signal defaults to HIGH, thus the RS485 is by default set to Receive and the bus is not blocked. Note that while there is the possibility to control CTS using GPIO with either CTS polarity, this has the downside of not being synchronous to the UART IP clock and thus glitchy and susceptible to slow DE switching. Second, on boot, before the UART driver probe callback is called, the driver core triggers pinctrl_init_done() and configures the IOMUXC to default state. At this point, UCR1 UARTEN and UCR2 RXEN are both still cleared, but UART CTS_B (RS485 DE) is configured as CTS function, thus the RTS signal is pulled HIGH by the UART IP CTS circuit. One part of the solution here is to enable UCR1 UARTEN and UCR2 RXEN and UTS loopback in this driver probe callback, thus unblocking the CTSC and CTS control early on. But this is still too late, since the pin control is already configured and CTS has been pulled HIGH for a short period of time. When Linux kernel boots and this driver is bound, the pin control is set to special "init" state if the state is available, and driver can switch the "default" state afterward when ready. This state can be used to set the CTS line as a GPIO in DT temporarily, and a GPIO hog can force such GPIO to LOW, thus keeping the RS485 DE line LOW early on boot. Once the driver takes over and UCR1 UARTEN and UCR2 RXEN and UTS loopback are all enabled, the driver can switch to "default" pin control state and control the CTS line as function instead. DT binding example is below: " &gpio6 { rts-init-hog { gpio-hog; gpios = <5 0>; output-low; line-name = "rs485-de"; }; }; &uart5 { /* DHCOM UART2 */ pinctrl-0 = <&pinctrl_uart5>; pinctrl-1 = <&pinctrl_uart5_init>; pinctrl-names = "default", "init"; ... }; pinctrl_uart5_init: uart5-init-grp { fsl,pins = < ...

It is also not inherently desired for the system to wakeup on Thunderbolt/USB4 hot plug events. However, we can still make user in control of waking up the system in the events of hot plug/unplug. This patch adds 'wakeup' attribute under 'usb4_portX/power' sysfs attribute and only enables wakes on connect/disconnect to the respective port when 'wakeup' is set to 'enabled'. The attribute is set to 'disabled' by default.

To be able to probe from one hardware description and to follow the pattern of other dual- mode controllers such as MUSB or MTU3 we need to collect the two, currently completely separate drivers in the same directory. After this, users need to select the main symbol USB_FOTG210 and then each respective subdriver. We pave the road to compile both drivers into the same kernel and select the one we want to use at probe() time, and possibly add OTG support in the end. This patch doesn't do much more than create the new symbol and collect the drivers in one place. We also add a comment for the section of dual-mode controllers in the Kconfig file so people can see what these selections are about. Also add myself as maintainer as there has been little response on my patches to these drivers.

Compile one module named "fotg210.ko" for both HCD and UDC drivers by collecting the init calls into a fotg210-core.c file and start to centralize things handling one and the same piece of hardware. Stub out the initcalls if one or the other part of the driver was not selected. Tested by compiling one or the other or both of the drivers into the kernel and as modules.

There is also a few quite confusing operations for checking the presense of TTYB_NORMAL. Simplify things by converting flags to bool. Despite the name remaining the same, the meaning of "flags" is altered slightly by this change. Previously it referred to flags of the buffer (only TTYB_NORMAL being used as a flag). After this change, flags tell whether the buffer contains/should be allocated with flags array along with character data array. It is much more suitable name that TTYB_NORMAL was for this purpose, thus the name remains.

If the transfer is still on-going, UART will trigger an interrupt and that eventually rearms the DMA Rx. The extra interrupt round-trip has an inherent latency cost that increases the risk of FIFO overrun. In such situations, the latency margin tends to already be less due to FIFO not being empty. Add check into DMA Rx completion handler to detect if LSR has DR (Data Ready) still set. DR indicates there will be more characters pending and DMA Rx can be rearmed right away to handle them.

The baudrate is generated with either a 16x or 13x divisor. The divisor is set in the Mode Definition Register 1 (MDR1). The commit erroneously assumes that the register stores the divisor as a bitmask and uses a logical AND to differentiate between 16x and 13x divisors. However the divisor is really stored as a 3-bit mode (see lines 363ff in include/uapi/linux/serial_reg.h). The logical AND operation is performed with UART_OMAP_MDR1_16X_MODE, which is defined as 0x0 and hence yields false. So the commit always assumes a 13x divisor. Fix by using an equal comparison. This works because we never set any of the other 5 bits in the register. (They pertain to IrDA mode, which is not supported by the driver).

Therefore, I refer to the newer 27.010 here. Chapter 5.1.8.1.1 describes the parameter negotiation messages and parameters. Chapter 5.4.1 states that the default parameters are to be used if no negotiation is performed. Chapter 5.4.6.3.1 describes the encoding of the parameter negotiation message. The meaning of the parameters and allowed value ranges can be found in chapter 5.7. Add parameter negotiation support accordingly. DLCI specific parameter configuration by the user requires additional ioctls. This is subject to another patch.

These mismatches are visible at compile time with the new -Wcast-function-type-strict in Clang[1]. Fix a total of 27 warnings like these: drivers/staging/ks7010/ks_wlan_net.c:2415:2: warning: cast from 'int (*)(struct net_device *, struct iw_request_info *, struct iw_point *, char *)' to 'iw_handler' (aka 'int (*)(struct net_device *, struct iw_request_info *, union iwreq_data *, char *)') converts to incompatible function type [-Wcast-function-type-strict] (iw_handler)ks_wlan_get_firmware_version,/* 3 KS_WLAN_GET_FIRM_VERSION */ ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The ks_wlan_net Wireless Extension handler callbacks (iw_handler) use a union for the data argument. Actually use the union and perform explicit member selection in the function body instead of having a function prototype mismatch. There are no resulting binary differences before/after changes.

This is done to avoid a conflict when a similar symbol is already in use in another part of kernel and may lead to conflicts. However, most of these base symbol names are not found to being used anywhere in the code and hence are not useful today. These symbols are not used outside of the module and hence can be safely removed. The code continues to use the original symbol names.

Currently, if the bus_type.match() function encounters an error that is not -EPROBE_DEFER, __driver_attach() will return a negative error code, which causes the driver registration logic to stop trying to match with the remaining devices on the bus. This behavior is not correct; a failure while matching a driver to a device does not mean that the driver won't be able to match and bind with other devices on the bus. Update the logic in __driver_attach() to reflect this.

This implements a driver which exports access to the CBMEM entries via sysfs under /sys/bus/coreboot/devices/cbmem-. This implementation is quite versatile. Examples of how it could be used are given below: * Tools like util/cbmem from the coreboot tree could use this driver instead of finding CBMEM in /dev/mem directly. Alternatively, firmware developers debugging an issue may find the sysfs interface more ergonomic than the cbmem tool and choose to use it directly. * The crossystem tool, which exposes verified boot variables, can use this driver to read the vboot work buffer. * Tools which read the BIOS SPI flash (e.g., flashrom) can find the flash layout in CBMEM directly, which is significantly faster than searching the flash directly. Write access is provided to all CBMEM regions via /sys/bus/coreboot/devices/cbmem-/mem, as the existing cbmem tooling updates this memory region, and envisioned use cases with crossystem can benefit from updating memory regions.

At the time "uio_dmem_genirq" was introduced, both had the same implementation of the 'uio_info' handlers irqcontrol() and handler(). Then commit 34cb27528398 ("UIO: Fix concurrency issue"), which was only applied to "uio_pdrv_genirq", ended up making them a little different. That commit, among other things, changed disable_irq() to disable_irq_nosync() in the implementation of irqcontrol(). The motivation there was to avoid a deadlock between irqcontrol() and handler(), since it added a spinlock in the irq handler, and disable_irq() waits for the completion of the irq handler. By changing disable_irq() to disable_irq_nosync() in irqcontrol(), we also avoid the sleeping-while-atomic bug that commit b74351287d4b ("uio: fix a sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") was trying to fix. Thus, this fixes the missing unlock in irqcontrol() by importing the implementation of irqcontrol() handler from the "uio_pdrv_genirq" driver. In the end, it reverts commit b74351287d4b ("uio: fix a sleep-in-atomic-context bug in uio_dmem_genirq_irqcontrol()") and change disable_irq() to disable_irq_nosync(). It is worth noting that this still does not address the concurrency issue fixed by commit 34cb27528398 ("UIO: Fix concurrency issue"). It will be addressed separately in the next commits.

In some cases it would be convenient to use it as right value in the assignment operation. But it can't be done as is, because compiler has no clue about the data layout.

For example the IP addresses in /proc/net/udp. When using emulation like qemu-user, applications are not guaranteed to be using the same byteorder as the kernel. Therefore the kernel needs to provide a way for applications to discover the byteorder used in API-filesystems. Using systemcalls is not enough because these are intercepted and translated by the emulation. Also this makes it easier for non-compiled applications like shellscripts to discover the byteorder.

This does nothing by itself, vmlinux is the same before and after this patch. But if a developer adds a .gnu.linkonce.foo record, that record is placed in the front of the section, where it can be used as a header for the table. The intent is to create an up-link to another organizing struct, from where related tables can be referenced. And since every item in a table has a known offset from its header, that same offset can be used to fetch records from the related tables. By itself, this doesnt gain much, unless maybe the pattern of access is to scan 1 or 2 fields in each fat record, but with 2 16 bit .map* fields added, we could de-duplicate 2 related tables. The use case here is struct _ddebug, which has 3 pointers (function, file, module) with substantial repetition; respectively 53%, 90%, and the module column is fully recoverable after dynamic_debug_init() splits the table into a linked list of "module" chunks. On a DYNAMIC_DEBUG=y kernel with 5k pr_debugs, the memory savings should be ~100 KiB.

It is not used anymore in core functions. By the way, function irq_of_parse_and_map() returns value 0 on error. In some drivers, NO_IRQ is erroneously used to check the return of irq_of_parse_and_map(). It is not a real bug today because the only architectures using the drivers being fixed by this patch define NO_IRQ as 0, but there are architectures which define NO_IRQ as -1. If one day those architectures start using the non fixed drivers, there will be a problem. Long time ago Linus advocated for not using NO_IRQ, see https://lkml.org/lkml/2005/11/21/221 . He re-iterated the same view recently in https://lkml.org/lkml/2022/10/12/622 So test !irq instead of tesing irq == NO_IRQ.

This reference count reaches zero when the device has been disconnected and there are no open file descriptors that are related to the device. When this occurs, kref_put() calls cleanup_dev(), which clears up the device's data, including the structure itself. However, when xillyusb_open() is called, this reference count becomes tricky: This function needs to obtain the xillyusb_dev structure that relates to the inode's major and minor (as there can be several such). xillybus_find_inode() (which is defined in xillybus_class.c) is called for this purpose. xillybus_find_inode() holds a mutex that is global in xillybus_class.c to protect the list of devices, and releases this mutex before returning. As a result, nothing protects the xillyusb_dev's reference counter from being decremented to zero before xillyusb_open() increments it on its own behalf. Hence the structure can be freed due to a rare race condition. To solve this, a mutex is added. It is locked by xillyusb_open() before the call to xillybus_find_inode() and is released only after the kref counter has been incremented on behalf of the newly opened inode. This protects the kref reference counters of all xillyusb_dev structs from being decremented by xillyusb_disconnect() during this time segment, as the call to kref_put() in this function is done with the same lock held. There is no need to hold the lock on other calls to kref_put(), because if xillybus_find_inode() finds a struct, xillyusb_disconnect() has not made the call to remove it, and hence not made its call to kref_put(), which takes place afterwards. Hence preventing xillyusb_disconnect's call to kref_put() is enough to ensure that the reference doesn't reach zero before it's incremented by xillyusb_open(). It would have been more natural to increment the reference count in xillybus_find_inode() of course, however this function is also called by Xillybus' driver for PCIe / OF, which registers a completely different structure. Therefore, xillybus_find_inode() treats these structures as void pointers, and accordingly can't make any changes.

Rename epss_l3 to clarify that it's affecting the PERF_STATE register and add a new L3_VOTE description. Given platform lineage it's assumed that the L3_VOTE-based case will be the predominant one, so use this for a new generic qcom,epss-l3 compatible. While adding the EPSS generic, also add qcom,osm-l3.

But it tried to do extra, adding KEEP(*(.gnu.linkonce.##_sec_)) to optionally reserve a header record in front of the data. It wrongly placed the KEEP after the linker-symbol starting the section, so if a header was added, it would wind up in the data. Moving the KEEP to the "correct" place proved brittle, and too clever by half. The obvious safe fix is to remove the KEEP and restore the plain old boilerplate. The header can be added later, with separate macros. Also, the macro var-names: _s_, _e_ are nearly invisible, change them to more obvious names: _BEGIN_, _END_ Fixes: 2f465b921bb8 ("vmlinux.lds.h: place optional header space in BOUNDED_SECTION") Signed-off-by: Jim Cromie Link: https://lore.kernel.org/r/20221117171633.923628-2-jim.cromie@gmail.com Signed-off-by: Greg Kroah-Hartman --- include/asm-generic/vmlinux.lds.h | 14 ++++++-------- 1 file changed, 6 insertions(+), 8 deletions(-) diff --git a/include/asm-generic/vmlinux.lds.h b/include/asm-generic/vmlinux.lds.h index b3ca56ac163f..c17f94785253 100644 --- a/include/asm-generic/vmlinux.lds.h +++ b/include/asm-generic/vmlinux.lds.h @@ -193,17 +193,15 @@ # endif #endif -#define BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _s_, _e_) \ - _s_##_label_ = .; \ - KEEP(*(.gnu.linkonce.##_sec_)) \ +#define BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, _BEGIN_, _END_) \ + _BEGIN_##_label_ = .; \ KEEP(*(_sec_)) \ - _e_##_label_ = .; + _END_##_label_ = .; -#define BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _s_, _e_) \ - _label_##_s_ = .; \ - KEEP(*(.gnu.linkonce.##_sec_)) \ +#define BOUNDED_SECTION_POST_LABEL(_sec_, _label_, _BEGIN_, _END_) \ + _label_##_BEGIN_ = .; \ KEEP(*(_sec_)) \ - _label_##_e_ = .; + _label_##_END_ = .; #define BOUNDED_SECTION_BY(_sec_, _label_) \ BOUNDED_SECTION_PRE_LABEL(_sec_, _label_, __start, __stop) From 1d926e259d8f8195fdfaeea7951149001894b473 Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Thu, 17 Nov 2022 10:16:33 -0700 Subject: [PATCH 0408/1098] vmlinux.lds.h: add HEADERED_SECTION_* macros These macros elaborate on BOUNDED_SECTION_(PRE|POST)_LABEL macros, prepending an optional KEEP(.gnu.linkonce##_sec_) reservation, and a linker-symbol to address it. This allows a developer to define a header struct (which must fit with the section's base struct-type), and could contain: 1- fields whose value is common to the entire set of data-records. This allows the header & data structs to specialize, complement each other, and shrink. 2- an uplink pointer to an organizing struct which refs other related/sub data-tables header record is addressable via the extern'd header linker-symbol Once the linker-symbols created by the macro are ref'd extern in code, that code can compute a record's index (ptr - start) in the "primary" table, then use it to index into the related/sub tables. Adding a primary.map_* field foreach sub-table would then allow deduplication and remapping of that sub-table. This is aimed at dyndbg's struct _ddebug __dyndbg[] section, whose 3 columns: function, file, module are 50%, 90%, 100% redundant. The module column is fully recoverable after dynamic_debug_init() saves it to each ddebug_table.module as the builtin __dyndbg[] table is parsed. Given that those 3 columns use 24/56 of a _ddebug record, a dyndbg=y kernel with ~5k callsites could reduce kernel memory substantially. Returning that memory to the kernel buddy-allocator? is then possible.

This is a bit of special case, so mimic the Kconfig incantations from DWC3: let the subdrivers for host or peripheral depend on the host or gadget support being =y or the same as the FOTG210 core itself. This should ensure that either: - The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled in and then the FOTG210 can be either module or compiled in. - The host or gadget is modular, and then the FOTG210 module must be a module too, or we cannot resolve the symbols at link time.

Commit 239071064732 ("partially Revert "usb: musb: Set the DT node on the child device"") broke probing for SoCs using ti-sysc interconnect target module as the dt node is not found. Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource from DT core") caused omap3 to fail with error "-ENXIO: IRQ mc not found" as the IRQ resources are no longer automatically populated from devicetree. Let's fix the issues by calling device_set_of_node_from_dev() only if the SoC has been updated to probe with ti-sysc. And for legacy SoCs, let's populate the resources manually as needed. Note that once we have updated the SoCs to probe with proper devicetree data in all cases, this is no longer needed. But doing that requires patching both devicetree and SoC code, so let's fix the probe issues first.

This synchronization is performed correctly, but only in case the chip indicates a pending interrupt in reg09 register. This fails to cover the situation where all interrupts reported by the chip were already handled by Linux before reboot, then the system rebooted, and then Linux starts again. In this case, the TUSB320 no longer reports any interrupts in reg09, and the state update does not perform any update as it depends on that interrupt indication. Fix this by turning tusb320_irq_handler() into a thin wrapper around tusb320_state_update_handler(), where the later now contains the bulk of the code of tusb320_irq_handler(), but adds new function parameter "force_update". The "force_update" parameter can be used by the probe function to assure that the state synchronization is always performed, independent of the interrupt indicated in reg09. The interrupt handler tusb320_irq_handler() callback uses force_update=false to avoid state updates on potential spurious interrupts and retain current behavior.

Such generic UART does not support DMA. In current code, sbsa_uart_pops and amba_pl011_pops share the same stop_rx operation, which will invoke pl011_dma_rx_stop, leading to an access of the DMACR register. This commit adds a using_rx_dma check in pl011_dma_rx_stop to avoid the access to DMACR register for SBSA UARTs which does not support DMA. When the kernel enables DMA engine with "CONFIG_DMA_ENGINE=y", Linux SBSA PL011 driver will access PL011 DMACR register in some functions. For most real SBSA Pl011 hardware implementations, the DMACR write behaviour will be ignored. So these DMACR operations will not cause obvious problems. But for some virtual SBSA PL011 hardware, like Xen virtual SBSA PL011 (vpl011) device, the behaviour might be different. Xen vpl011 emulation will inject a data abort to guest, when guest is accessing an unimplemented UART register. As Xen VPL011 is SBSA compatible, it will not implement DMACR register. So when Linux SBSA PL011 driver access DMACR register, it will get an unhandled data abort fault and the application will get a segmentation fault: Unhandled fault at 0xffffffc00944d048 Mem abort info: ESR = 0x96000000 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x00: ttbr address size fault Data abort info: ISV = 0, ISS = 0x00000000 CM = 0, WnR = 0 swapper pgtable: 4k pages, 39-bit VAs, pgdp=0000000020e2e000 [ffffffc00944d048] pgd=100000003ffff803, p4d=100000003ffff803, pud=100000003ffff803, pmd=100000003fffa803, pte=006800009c090f13 Internal error: ttbr address size fault: 96000000 [#1] PREEMPT SMP ...

Zhengchao Shao identified by inspection bugs in the error path of hdlcdev_open() in synclink_gt.c The function did not fully unwind actions in the error path. The use of try_module_get()/module_put() is unnecessary, potentially hazardous and is removed. The synclink_gt driver is already pinned any point the net device is registered, a requirement for calling this entry point. The call hdlc_open() to init the generic HDLC layer is moved to after driver level init/checks and proper rollback of previous actions is added. This is a more sensible ordering as the most common error paths are at the driver level and the driver level rollbacks require less processing than hdlc_open()/hdlc_close(). This has been tested with supported hardware.

Add lpuart_uport_is_active() to determine if the uart port needs to get into the suspend states, also add lpuart_suspend_noirq() and lpuart_resume_noirq() to enable and disable the wakeup irq bits if the uart port needs to be set as wakeup source. When use lpuart with DMA mode, it still needs to switch to the cpu mode in .suspend() that enable cpu interrupts RIE and RXEDGIE as wakeup source, after system resume back, needs to setup DMA again, .resume() will share the HW setup code with .startup(), so abstract the same code to the api like lpuart32_hw_setup().

This means when the character is last and uart calls ops->stop_tx(), the character is not sent at all. The usart datasheet is not much specific on this, it just says the transmitter is stopped. But apparently, the character is dropped. So we should stop the transmitter only for DMA and PDC transfers to not send any more characters. For PIO, this is unexpected and deviates from other drivers. In particular, the below referenced commit broke TX as it added a call to ->stop_tx() after the very last character written to the transmitter. So fix this by limiting the write of ATMEL_US_TXDIS to DMA transfers only. Even there, I don't know if it is correctly implemented. Are all the queued characters sent once ->start_tx() is called? Anyone tested flow control -- be it hard (RTSCTS) or the soft (XOFF/XON) one?

For resets that follow errors, it disables the option to debug the errors on both the device side and the user application side. This patch adds a 'graceful hard reset' option and a new hl_device_cond_reset() function. Under some conditions, mainly if there is no user process or if he is not registered to driver notifications, this function will execute hard reset as usual. Otherwise, the reset will be postponed and a notification will be sent to user, to let him perform post-error actions and then to release the device, after which reset will take place. If device is not released by user in some defined time, a watchdog work will execute the reset in any case.

If that doesn't happen, only a device reset will revert it back to an operational state, i.e. need to wait for a CS timeout or an error, or to wait for an external intervention of injecting a reset via sysfs. At this stage, after the device was released by user, context is held either because of CS which were left running on the device and are not relevant anymore, or due to missing cleanup steps from user side. All of this is in any case handled in the device reset flow, so initiate the reset at this point instead of waiting for it.

The send is done via synchronous/blocking function to ensure that firmware is in ready state. However, in case of firmware undergoing reset send might be block forever. To address this issue a timeout is added to blocking write command on the internal bus. Introduce the __mei_cl_send_timeout function to use instead of __mei_cl_send in cases where timeout is required. The mei_cl_write has only two callers and there is no need to split it into two functions.

Nvmem devices can produce nvmem cells. The current way to describe nvmem cells is to locate them by providing their static byte and bit offset and length. These information are stored in subnodes of the nvmem device. It is now a fact that such description does not fit more advanced use cases where the location or the size of the cells may vary. There are currently three known situations which require being described differently: Kontron's SL28 VPD, ONIE's TLV table and U-Boot's environment variables. Hence, we need a way to describe the parsers that must be used in order to make the dynamic discovery of the nvmem cells. This new description must fit both use cases (the generic situation and the MTD case). Let's create in both cases a container node named nvmem-layout whose content will depend on the parser. Right now nvmem-layout.yaml is "empty", but references to additional layout parser bindings will be inserted in the near future. The final goal being something that looks like: * Most cases (EEPROM & co): eeprom@x { compatible = ""; ... nvmem-layout { compatible = ""; ... }; }; * MTD case: flash@y { compatible = ""; ... otp { compatible = "user-otp"; /* or "factory-otp" */ ... nvmem-layout { compatible = ""; ... }; }; }; Signed-off-by: Miquel Raynal Reviewed-by: Rob Herring Signed-off-by: Srinivas Kandagatla Link: https://lore.kernel.org/r/20221118063932.6418-10-srinivas.kandagatla@linaro.org Signed-off-by: Greg Kroah-Hartman --- .../bindings/nvmem/layouts/nvmem-layout.yaml | 30 +++++++++++++++++++ .../devicetree/bindings/nvmem/nvmem.yaml | 7 +++++ 2 files changed, 37 insertions(+) create mode 100644 Documentation/devicetree/bindings/nvmem/layouts/nvmem-layout.yaml diff --git a/Documentation/devicetree/bindings/nvmem/layouts/nvmem-layout.yaml b/Documentation/devicetree/bindings/nvmem/layouts/nvmem-layout.yaml new file mode 100644 index 000000000000..ecc7c37cbc1f --- /dev/null +++ b/Documentation/devicetree/bindings/nvmem/layouts/nvmem-layout.yaml @@ -0,0 +1,30 @@ +# SPDX-License-Identifier: (GPL-2.0 OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/nvmem/layouts/nvmem-layout.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: NVMEM (Non Volatile Memory) layouts + +maintainers: + - Srinivas Kandagatla + - Michael Walle + - Miquel Raynal + +description: | + Most NVMEM layouts are static and thus do not require additional description + besides the bytes/bits offset and length.

This patch also documents cur_phonetic as a sysfs attribute in sysfs-driver-speakup. When cur_phonetic=1, it causes speakup to speak letters phonetically if paused on the character while arrowing through a word.

Update kernel to reflect these changes, i.e. do the following: - adding a comment explaining that it's not used anymore - replacing the specific type by a raw buffer - updating the example code accordingly The advertised field confused users and actually never been used. So the wrong part here is that kernel puts something which userspace never used and hence this may confuse a reader of this code.

The decision was taken that if measurement is not requested within 2 seconds the sensor will remain in SLEEP_STEP power mode, where measurements are triggered on request with setting the start of measurement bit (SOB). In this mode the measurements are taking a bit longer because we need to start it and complete it. Currently, in continuous mode we read ready data and this mode is activated if sensor measurement is requested within 2 seconds. The suspend timeout is increased to 6 seconds (instead of 3 before), because that enables more measurements in lower power mode (SLEEP_STEP), with the lowest refresh rate (2 seconds).

Hence, in this case, a new lock was introduced in the state structure. Note that the goal is not to introduce any functional change and that is the reason why a new lock was introduced to guarantee 2). While at it, properly include "mutex.h" for mutex related APIs.

Inputs and references can be buffered internally. Inputs can also be amplified with internal PGA. Device has four digital filter modes: FIR50/60, FIR50, FIR60 and SINC4. FIR 50Hz and 60Hz rejections can be enabled/disabled separately. Digital filter selection affects sampling frequency range so driver has to consider the configured filter when configuring sampling frequency.

Claim Buffered mode; 2: If 1) succeeds call max30102_get_temp() without powering on the device; 3: Release Buffered mode; 4: If 1) fails, Claim Direct mode; 5: If 4) succeeds call max30102_get_temp() with powering on the device; 6: Release Direct mode; 7: If 4) fails, goto to 1) and try again. This dance between buffered and direct mode is not particularly pretty (as well as the loop introduced by the goto statement) but it does allow us to get rid of the mlock usage while keeping the same behavior.

Power from all internal circuits and registers is removed. This is done by pulling the SHDN pin to low. This patch enables runtime PM on MPL115 to increase power savings. According to spec., a wakeup time period of ~5 ms exists between waking up and actually communicating with the device. This is implemented using sleep delay.

The sensor features include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ, tap/motion detection, wake-up & back-to-sleep events, four acceleration ranges (2, 4, 8 and 16g), and probably some other cool features. Add support for the basic accelerometer features such as getting the acceleration data via IIO. (raw reads, triggered buffer [data-ready] or using the WMI IRQ). Important things to be added include the double-tap, motion detection and wake-up as well as the runtime power management.

This expectation was not forced by the API - and some drivers did register attributes created by IIO_CONST_ATTR(). When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy the pointer to stored string constant and when the sysfs file is read the kernel will access to invalid location. Change the function signatures to expect an array of iio_dev_attrs to avoid similar errors in the future. Merge conflict resolved whilst applying due to patch crossing with two new drivers (kx022a accelerometer and ad4130 ADC).

Hence in the expression voltage_offset * AD74413R_ADC_RESULT_MAX, voltage_offset is first promoted to unsigned long, and since it may be negative, that results in a garbage value. For example, when range is AD74413R_ADC_RANGE_5V_BI_DIR, voltage_offset is -2500 and voltage_range is 5000, so the RHS of this assignment is, depending on sizeof(long), either 826225UL or 3689348814709142UL, which after truncation to int then results in either 826225 or 1972216214 being the output from in_currentX_offset. Casting to int avoids that promotion and results in the correct -32767 output.

The AD74115H provides a wide range of use cases, integrated on a single chip. These use cases include analog output, analog input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. The AD74115H also has an integrated HART modem. A serial peripheral interface (SPI) is used to handle all communications to the device, including communications with the HART modem. The digital input and digital outputs can be accessed via the SPI or the general-purpose input and output (GPIO) pins to support higher speed data rates. The device features a 16-bit, sigma-delta analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The AD74115H contains a high accuracy 2.5 V on-chip reference that can be used as the DAC and ADC reference.

The AD74115H provides a wide range of use cases, integrated on a single chip. These use cases include analog output, analog input, digital output, digital input, resistance temperature detector (RTD), and thermocouple measurement capability. The AD74115H also has an integrated HART modem. A serial peripheral interface (SPI) is used to handle all communications to the device, including communications with the HART modem. The digital input and digital outputs can be accessed via the SPI or the general-purpose input and output (GPIO) pins to support higher speed data rates. The device features a 16-bit, sigma-delta analog-to-digital converter (ADC) and a 14-bit digital-to-analog converter (DAC). The AD74115H contains a high accuracy 2.5 V on-chip reference that can be used as the DAC and ADC reference.

17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 23 Nov 2022 13:25:19 +0100 Subject: [PATCH 0952/1098] driver core: make struct class.dev_uevent() take a const * The dev_uevent() in struct class should not be modifying the device that is passed into it, so mark it as a const * and propagate the function signature changes out into all relevant subsystems that use this callback.

Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

Therefore depending on COMPILE_TEST as an alternative is no longer needed. It is actually better to always build such drivers with OF enabled, so that the test builds are closer to how each driver will actually be built on its intended target. Building them without OF may not test much as the compiler will optimize out potentially large parts of the code. In the worst case, this could even pop false positive warnings. Dropping COMPILE_TEST here improves the quality of our testing and avoids wasting time on non-existent issues.

It appears to be caused by ulpi_read_id() masking the timeout on the first test write. In the past dwc3 probe continued by calling dwc3_core_soft_reset() followed by dwc3_get_extcon() which happend to return -EPROBE_DEFER. On deferred probe ulpi_read_id() finally succeeded. Due to above mentioned rearranging -EPROBE_DEFER is not returned and probe completes without phy. On Intel Merrifield the timeout on the first test write issue is reproducible but it is difficult to find the root cause. Using a mainline kernel and rootfs with buildroot ulpi_read_id() succeeds. As soon as adding ftrace / bootconfig to find out why, ulpi_read_id() fails and we can't analyze the flow. Using another rootfs ulpi_read_id() fails even without adding ftrace. We suspect the issue is some kind of timing / race, but merely retrying ulpi_read_id() does not resolve the issue. As we now changed ulpi_read_id() to return -ETIMEDOUT in this case, we need to handle the error by calling dwc3_core_soft_reset() and request -EPROBE_DEFER.

A search of the uvc-gadget application and all the forks that I could find for it did not reveal any users either.
