Because we support a single user, we can reset the device (if needs to) after a user closes its file descriptor to make sure the device is in idle and clean state for the next user. - Add a new feature to allow the user to wait on interrupt. This is needed for future ASICs - Replace GFP_ATOMIC with GFP_KERNEL wherever possible and add code to support failure of allocating with GFP_ATOMIC. - Update code to support the latest firmware image: - More security features are done in the firmware - Remove hard-coded assumptions and replace them with values that are sent to the firmware on loading. - Print device unusable error - Reset device in case the communication between driver and firmware gets out of sync. - Support new PCI device ids for secured GAUDI. - Expose current power draw through the INFO IOCTL. - Support resetting the device upon a request from the BMC (through F/W). - Always use only a single MSI in GAUDI, due to H/W limitation. - Improve data-path code by taking out code from spinlock protection. - Allow user to specify custom timeout per Command Submission. - Some enhancements to debugfs. - Various minor changes and improvements. ---------------------------------------------------------------- Alon Mizrahi (1): habanalabs: add custom timeout flag per cs Bharat Jauhari (1): habanalabs: move dram scrub to free sequence Koby Elbaz (2): habanalabs: improve utilization calculation habanalabs: support DEVICE_UNUSABLE error indication from FW Oded Gabbay (11): habanalabs: reset after device is actually released habanalabs: fail reset if device is not idle habanalabs: reset_upon_device_release is for bring-up habanalabs: print if device is used on FD close habanalabs: change default CS timeout to 30 seconds habanalabs: use correct define for 32-bit max value habanalabs/gaudi: always use single-msi mode habanalabs/gaudi: add debugfs to DMA from the device habanalabs: remove the store jobs array from CS IOCTL habanalabs: use strscpy instead of sprintf and strlcpy habanalabs: print f/w boot unknown error Ofir Bitton (13): habanalabs: add reset support when user closes FD habanalabs: enable all IRQs for user interrupt support habanalabs: wait for interrupt support habanalabs: use a single FW loading bringup flag habanalabs/gaudi: update extended async event header habanalabs: replace GFP_ATOMIC with GFP_KERNEL habanalabs: debugfs access to user mapped host addresses habanalabs/gaudi: reset device upon BMC request habanalabs/gaudi: unsecure TPC cfg status registers habanalabs/gaudi: Update async events header habanalabs: move relevant datapath work outside cs lock habanalabs/gaudi: derive security status from pci id habanalabs/gaudi: skip iATU if F/W security is enabled Ohad Sharabi (6): habanalabs: reset device in case of sync error habanalabs: skip DISABLE PCI packet to FW on heartbeat habanalabs: update hl_boot_if.h habanalabs: support legacy and new pll indexes habanalabs: send dynamic msi-x indexes to f/w habanalabs: update to latest F/W communication header Sagiv Ozeri (2): habanalabs: support HW blocks vm show habanalabs: return current power via INFO IOCTL Tomer Tayar (1): habanalabs/gaudi: clear QM errors only if not in stop_on_err mode Yang Li (1): habanalabs: Switch to using the new API kobj_to_dev() farah kassabri (3): habanalabs: set max asid to 2 habanalabs: avoid soft lockup bug upon mapping error habanalabs/gaudi: sync stream add protection to SOB reset flow .../ABI/testing/debugfs-driver-habanalabs | 70 +++- drivers/misc/habanalabs/common/command_buffer.c | 12 +- .../misc/habanalabs/common/command_submission.c | 368 +++++++++++++++++---- drivers/misc/habanalabs/common/context.c | 14 +- drivers/misc/habanalabs/common/debugfs.c | 224 +++++++++++-- drivers/misc/habanalabs/common/device.c | 221 ++++++------- drivers/misc/habanalabs/common/firmware_if.c | 238 +++++++++++-- drivers/misc/habanalabs/common/habanalabs.h | 184 ++++++++--- drivers/misc/habanalabs/common/habanalabs_drv.c | 28 +- drivers/misc/habanalabs/common/habanalabs_ioctl.c | 35 +- drivers/misc/habanalabs/common/hw_queue.c | 10 +- drivers/misc/habanalabs/common/irq.c | 56 ++++ drivers/misc/habanalabs/common/memory.c | 182 +++++++--- drivers/misc/habanalabs/common/mmu/mmu.c | 3 + drivers/misc/habanalabs/common/pci/pci.c | 52 +++ drivers/misc/habanalabs/common/sysfs.c | 33 +- drivers/misc/habanalabs/gaudi/gaudi.c | 357 +++++++++++++++++--- drivers/misc/habanalabs/gaudi/gaudiP.h | 3 + drivers/misc/habanalabs/gaudi/gaudi_security.c | 8 - drivers/misc/habanalabs/goya/goya.c | 140 +++++++- drivers/misc/habanalabs/goya/goyaP.h | 2 + drivers/misc/habanalabs/include/common/cpucp_if.h | 99 +++++- .../misc/habanalabs/include/common/hl_boot_if.h | 219 ++++++++++++ drivers/misc/habanalabs/include/gaudi/gaudi.h | 2 +- .../habanalabs/include/gaudi/gaudi_async_events.h | 2 + .../include/gaudi/gaudi_async_ids_map_extended.h | 43 ++- .../misc/habanalabs/include/gaudi/gaudi_fw_if.h | 14 - drivers/misc/habanalabs/include/goya/goya.h | 2 +- .../habanalabs/include/goya/goya_async_events.h | 1 + drivers/misc/habanalabs/include/goya/goya_fw_if.h | 11 - include/uapi/misc/habanalabs.h | 77 +++-- 31 files changed, 2193 insertions(+), 517 deletions(-)
