Commit 788019eb559f ("genirq: Retain disable depth for managed interrupts
across CPU hotplug") tried to make managed shutdown/startup properly
reference counted, but it missed the fact that the unplug and hotplug code
has an intentional imbalance by skipping IRQS_SUSPENDED interrupts on
the "restore" path.
This means that if a managed-affinity interrupt was both suspended and
managed-shutdown (such as may happen during system suspend / S3), resume
skips calling irq_startup_managed(), and would again have an unbalanced
depth this time, with a positive value (i.e., remaining unexpectedly
masked).
This IRQS_SUSPENDED check was introduced in commit a60dd06af6
("genirq/cpuhotplug: Skip suspended interrupts when restoring affinity")
for essentially the same reason as commit 788019eb559f, to prevent that
irq_startup() would unconditionally re-enable an interrupt too early.
Because irq_startup_managed() now respsects the disable-depth count, the
IRQS_SUSPENDED check is not longer needed, and instead, it causes harm.
Thus, drop the IRQS_SUSPENDED check, and restore balance.
This effectively reverts commit a60dd06af6 ("genirq/cpuhotplug: Skip
suspended interrupts when restoring affinity"), because it is replaced
by commit 788019eb559f ("genirq: Retain disable depth for managed
interrupts across CPU hotplug").

(cherry picked from commit 72218d74c9c57b8ea36c2a58875dff406fc10462
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq/urgent)
Commit 788019eb559f ("genirq: Retain disable depth for managed interrupts
across CPU hotplug") intended to only decrement the disable depth once per
managed shutdown, but instead it decrements for each CPU hotplug in the
affinity mask, until its depth reaches a point where it finally gets
re-started.
For example, consider:
1. Interrupt is affine to CPU {M,N}
2. disable_irq() -> depth is 1
3. CPU M goes offline -> interrupt migrates to CPU N / depth is still 1
4. CPU N goes offline -> irq_shutdown() / depth is 2
5. CPU N goes online
-> irq_restore_affinity_of_irq()
-> irqd_is_managed_and_shutdown()==true
-> irq_startup_managed() -> depth is 1
6. CPU M goes online
-> irq_restore_affinity_of_irq()
-> irqd_is_managed_and_shutdown()==true
-> irq_startup_managed() -> depth is 0
*** BUG: driver expects the interrupt is still disabled ***
-> irq_startup() -> irqd_clr_managed_shutdown()
7. enable_irq() -> depth underflow / unbalanced enable_irq() warning
This should clear the managed-shutdown flag at step 6, so that further
hotplugs don't cause further imbalance.
Note: It might be cleaner to also remove the irqd_clr_managed_shutdown()
invocation from __irq_startup_managed(). But this is currently not possible
because of irq_update_affinity_desc() as it sets IRQD_MANAGED_SHUTDOWN and
expects irq_startup() to clear it.

Affinity-managed IRQs may be shut down and restarted during CPU
hotunplug/plug, and the IRQ may be left in an unexpected state.
Specifically:
1. IRQ affines to CPU N
2. disable_irq() -> depth is 1
3. CPU N goes offline
4. irq_shutdown() -> depth is set to 1 (again)
5. CPU N goes online
6. irq_startup() -> depth is set to 0 (BUG! client expected IRQ is
still disabled)
7. enable_irq() -> depth underflow / unbalanced enable_irq() WARN
It seems depth only needs preserved for managed IRQs + CPU hotplug, so
per Thomas's recommendation, we make that explicit.
I add kunit tests that cover some of this in a following patch.

[ Upstream commit c3164d2e0d181027da8fc94f8179d8607c3d440f ]
Setting pci_msi_ignore_mask inhibits the toggling of the mask bit for both
MSI and MSI-X entries globally, regardless of the IRQ chip they are using.
Only Xen sets the pci_msi_ignore_mask when routing physical interrupts over
event channels, to prevent PCI code from attempting to toggle the maskbit,
as it's Xen that controls the bit.
However, the pci_msi_ignore_mask being global will affect devices that use
MSI interrupts but are not routing those interrupts over event channels
(not using the Xen pIRQ chip). One example is devices behind a VMD PCI
bridge. In that scenario the VMD bridge configures MSI(-X) using the
normal IRQ chip (the pIRQ one in the Xen case), and devices behind the
bridge configure the MSI entries using indexes into the VMD bridge MSI
table. The VMD bridge then demultiplexes such interrupts and delivers to
the destination device(s). Having pci_msi_ignore_mask set in that scenario
prevents (un)masking of MSI entries for devices behind the VMD bridge.
Move the signaling of no entry masking into the MSI domain flags, as that
allows setting it on a per-domain basis. Set it for the Xen MSI domain
that uses the pIRQ chip, while leaving it unset for the rest of the
cases.
Remove pci_msi_ignore_mask at once, since it was only used by Xen code, and
with Xen dropping usage the variable is unneeded.
This fixes using devices behind a VMD bridge on Xen PV hardware domains.
Albeit Devices behind a VMD bridge are not known to Xen, that doesn't mean
Linux cannot use them. By inhibiting the usage of
VMD_FEAT_CAN_BYPASS_MSI_REMAP and the removal of the pci_msi_ignore_mask
bodge devices behind a VMD bridge do work fine when use from a Linux Xen
hardware domain. That's the whole point of the series.

[ Upstream commit 8d187a77f04c14fb459a5301d69f733a5a1396bc ]
Commit 1b57d91b96 ("irqchip/gic-v2, v3: Prevent SW resends entirely")
sett the flag which enforces interrupt handling in interrupt context and
prevents software base resends for ARM GIC v2/v3.
But it missed that the helper function which checks the flag was hidden
behind CONFIG_GENERIC_PENDING_IRQ, which is not set by ARM[64].
Make the helper unconditionally available so that the enforcement actually
works.

Add new hooks for debugging for disksleep tasks.
It helps the bootloader and the panic handler produce debugging
information about what the tasks are waiting for. It can be obtained
through Ramdump or kernel log, and this information can be used to
quickly classify and respond to problems.

Vendor kernel modules may implement irq balancers, which could
take irq desc lock of an irq and then based on current affinity
mask or affinity hint, reconfigure the affinity of that irq.
For example : For an irq, for which affinity is broken i.e. all
the cpus in its affinity mask have gone offline. For such irqs,
we might want to reset the affinity, when the original set of
affined cpus, come back online. desc->affinity_hint can be used
for figuring out the original affinity. So, the sequence for doing
this becomes:
desc = irq_to_desc(i);
raw_spin_lock(&desc->lock);
affinity = desc->affinity_hint;
raw_spin_unlock(&desc->lock);
irq_set_affinity_hint(i, affinity);
Here, we need to release the desc lock before calling the exported
api irq_set_affinity_hint(). This creates a window where, after
unlocking desc lock and before calling irq_set_affinity_hint(),
where this setting can race with other irq_set_affinity_hint()
callers. So, export irq_do_set_affinity() symbol to provide an
api, which can be called with desc lock held.

The error path in msi_domain_alloc(), frees the already allocated MSI
interrupts in a loop, but the loop condition terminates when the index
reaches zero, which fails to free the first allocated MSI interrupt at
index zero.
Check for >= 0 so that msi[0] is freed as well.

The kernel already knows at the time of interrupt allocation whether
affinity of an interrupt can be controlled by userspace or not.
It still creates all related procfs control files with read/write
permissions. That's inconsistent and non-intuitive for system
administrators and tools.
Therefore set the file permissions to read-only for such interrupts.

Kunkun Jiang reports that for a workload involving the simultaneous startup
of a large number of VMs (for a total of about 200 vcpus), a lot of CPU
time gets spent on spinning on the tmp_mask_lock that exists as a static
raw spinlock in irq_do_set_affinity(). This lock protects a global cpumask
(tmp_mask) that is used as a temporary variable to compute the resulting
affinity.
While this is triggered by KVM issuing a irq_set_affinity() call each time
a vcpu is about to execute, it is obvious that having a single global
resource is not very scalable.
Since a cpumask can be a fairly large structure on systems with a high core
count, a stack allocation is not really appropriate. Instead, turn the
global cpumask into a per-CPU variable, removing the need for locking
altogether as the code is executed with preemption and interrupts disabled.

The unification of irq_domain_create_legacy() missed the fact that
interrupts must be associated even when the Linux interrupt number provided
in the first_irq argument is 0.
This breaks all call sites of irq_domain_create_legacy() which supply 0 as
the first_irq argument.
Enforce the association for legacy domains in __irq_domain_instantiate() to
cure this.

Devices can provide multiple interrupt lines. One reason for this is that
a device has multiple subfunctions, each providing its own interrupt line.
Another reason is that a device can be designed to be used (also) on a
system where some of the interrupts can be routed to another processor.
A line often further acts as a demultiplex for specific interrupts
and has it's respective set of interrupt (status, mask, ack, ...)
registers.
Regmap supports the handling of these registers and demultiplexing
interrupts, but the interrupt domain code ends up assigning the same name
for the per interrupt line domains. This causes a naming collision in the
debugFS code and leads to confusion, as /proc/interrupts shows two separate
interrupts with the same domain name and hardware interrupt number.
Instead of adding a workaround in regmap or driver code, allow giving a
name suffix for the domain name when the domain is created.
Add a name_suffix field in the irq_domain_info structure and make
irq_domain_instantiate() use this suffix if it is given when a domain is
created.

irq_domain_create_simple() and irq_domain_create_legacy() use
__irq_domain_instantiate(), but have extra handling of allocating interrupt
descriptors and associating interrupts in them. Some of that is duplicated.
There are also call sites which have conditonals to invoke different
interrupt domain creator functions, where one of them is usually
irq_domain_create_legacy(). Alternatively they associate the interrupts for
the legacy case after creating the domain.
Moving the extra logic of irq_domain_create_simple()/legacy() into
__irq_domain_instantiate() allows to consolidate that.
Introduce hwirq_base and virq_base members in the irq_domain_info
structure, which allows to transport the required information and add the
conditional interrupt descriptor allocation and interrupt association into
__irq_domain_instantiate().
This reduces irq_domain_create_legacy() and irq_domain_create_simple() to
trivial wrappers which fill in the info structure and allows call sites
which must support the legacy case along with more modern mechanism to
select the domain type via the parameters of the info struct.

Currently, whenever a caller is providing an affinity hint for an
interrupt, the allocation code uses it to calculate the node and copies the
cpumask into irq_desc::affinity.
If the affinity for the interrupt is not marked 'managed' then the startup
of the interrupt ignores irq_desc::affinity and uses the system default
affinity mask.
Prevent this by setting the IRQD_AFFINITY_SET flag for the interrupt in the
allocator, which causes irq_setup_affinity() to use irq_desc::affinity on
interrupt startup if the mask contains an online CPU.

Various PCI controllers that mux MSIs onto a single IRQ line produce these
"IRQ%d: set affinity failed" warnings when entering suspend. This has been
discussed before [1] [2] and an example test case is included at the end of
this commit message.
Controller drivers that create MSI IRQ domain with
MSI_FLAG_USE_DEF_CHIP_OPS and do not override the .irq_set_affinity()
irqchip callback get assigned the default msi_domain_set_affinity()
callback. That is not desired on controllers where it is not possible to
set affinity of each MSI IRQ line to a specific CPU core due to hardware
limitation.
Introduce flag MSI_FLAG_NO_AFFINITY, which keeps .irq_set_affinity() unset
if the controller driver did not assign it. This way, migrate_one_irq()
can exit right away, without printing the warning. The .irq_set_affinity()
implementations which only return -EINVAL can be removed from multiple
controller drivers.

Pull interrupt subsystem updates from Thomas Gleixner:
"Core:
- Provide a new mechanism to create interrupt domains. The existing
interfaces have already too many parameters and it's a pain to
expand any of this for new required functionality.
The new function takes a pointer to a data structure as argument.
The data structure combines all existing parameters and allows for
easy extension.
The first extension for this is to handle the instantiation of
generic interrupt chips at the core level and to allow drivers to
provide extra init/exit callbacks.
This is necessary to do the full interrupt chip initialization
before the new domain is published, so that concurrent usage sites
won't see a half initialized interrupt domain. Similar problems
exist on teardown.
This has turned out to be a real problem due to the deferred and
parallel probing which was added in recent years.
Handling this at the core level allows to remove quite some accrued
boilerplate code in existing drivers and avoids horrible
workarounds at the driver level.

Currently users of the interrupt simulator don't have any way of being
notified about interrupts from the simulated domain being requested or
released. This causes a problem for one of the users - the GPIO
simulator - which is unable to lock the pins as interrupts.
Define a structure containing callbacks to be executed on various
irq_sim-related events (for now: irq request and release) and provide an
extended function for creating simulated interrupt domains that takes it
and a pointer to custom user data (to be passed to said callbacks) as
arguments.
