The change prevents random (rare) out-of-sync errors. - Notify F/W to start sending events only after initialization of device is done. This fixes the issue where fatal events were received but ignored. - Fix integer handling (static analysis warning). - Always fetch HBM ECC errors from F/W (if available). - Minor fix in GAUDI-specific initialization code. ---------------------------------------------------------------- Oded Gabbay (4): habanalabs: fix integer handling issue habanalabs: enable F/W events after init done habanalabs: return block size + block ID habanalabs/gaudi: don't enable clock gating on DMA5 Ofir Bitton (2): habanalabs: improve communication protocol with cpucp habanalabs: support fetching first available user CQ Ohad Sharabi (2): habanalabs/gaudi: use HBM_ECC_EN bit for ECC ERR habanalabs: update security map after init CPU Qs drivers/misc/habanalabs/common/device.c | 23 ++++++++-- drivers/misc/habanalabs/common/firmware_if.c | 14 ++++++- drivers/misc/habanalabs/common/habanalabs.h | 15 +++++-- drivers/misc/habanalabs/common/habanalabs_ioctl.c | 3 +- drivers/misc/habanalabs/common/memory.c | 19 +++++---- drivers/misc/habanalabs/common/mmu/mmu.c | 2 +- drivers/misc/habanalabs/gaudi/gaudi.c | 49 ++++++++++++++++++---- drivers/misc/habanalabs/goya/goya.c | 27 +++++++++--- .../misc/habanalabs/include/common/hl_boot_if.h | 5 +++ include/uapi/misc/habanalabs.h | 30 ++++++++++--- 10 files changed, 148 insertions(+), 39 deletions(-)
