Merge tag 'misc-habanalabs-next-2022-11-23' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into char-misc-next
Oded writes: This tag contains habanalabs driver changes for v6.2: - New feature of graceful hard-reset. Instead of immediately killing the user-process when a command submission times out, we wait a bit and give the user-process notification and let it try to close things gracefully, with the ability to retrieve debug information. - Enhance the EventFD mechanism. Add new events such as access to illegal address (RAZWI), page fault, device unavailable. In addition, change the event workqueue to be handled in a single-threaded workqueue. - Allow the control device to work during reset of the ASIC, to enable monitoring applications to continue getting the data. - Add handling for Gaudi2 with PCI revision 2. - Reduce severity of prints due to power/thermal events. - Change how we use the h/w to perform memory scrubbing in Gaudi2. - Multiple bug fixes, refactors and renames. * tag 'misc-habanalabs-next-2022-11-23' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux: (63 commits) habanalabs: fix VA range calculation habanalabs: fail driver load if EEPROM errors detected habanalabs: make print of engines idle mask more readable habanalabs: clear non-released encapsulated signals habanalabs: don't put context in hl_encaps_handle_do_release_sob() habanalabs: print context refcount value if hard reset fails habanalabs: add RMWREG32_SHIFTED to set a val within a mask habanalabs: fix rc when new CPUCP opcodes are not supported habanalabs/gaudi2: added memset for the cq_size register habanalabs: added return value check for hl_fw_dynamic_send_clear_cmd() habanalabs: increase the size of busy engines mask habanalabs/gaudi2: change memory scrub mechanism habanalabs: extend process wait timeout in device fine habanalabs: check schedule_hard_reset correctly habanalabs: reset device if still in use when released habanalabs/gaudi2: return to reset upon SM SEI BRESP error habanalabs/gaudi2: don't enable entries in the MSIX_GW table habanalabs/gaudi2: remove redundant firmware version check habanalabs/gaudi: fix print for firmware-alive event habanalabs: fix print for out-of-sync and pkt-failure events ...
