Hi Dave, Sima. Habanalabs pull request for 6.9. No uapi changes this time. Just minor features, improvements, code cleanups and bug fixes. Also one small change in accel subsystem file. Full details are in the signed tag. Thanks, Oded The following changes since commit 40d47c5fb4f2a7c1ef168598f01bdcbd31ba4038: Merge tag 'amd-drm-next-6.9-2024-02-19' of https://gitlab.freedesktop.org/agd5f/linux into drm-next (2024-02-22 13:21:19 +1000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux.git tags/drm-habanalabs-next-2024-02-26 for you to fetch changes up to 576d7cc5a9e29e4cc579ffb0f9afc209e34eea31: accel: constify the struct device_type usage (2024-02-26 09:59:18 +0200) ---------------------------------------------------------------- This tag contains habanalabs driver and accel changes for v6.9. The notable changes are: - New features and improvements: - Configure interrupt affinity according to NUMA nodes for the MSI-X interrupts that are assigned to the userspace application which acquires the device. - Move the HBM MMU page tables to reside inside the HBM to minimize latency when doing page-walks. - Improve the device reset mechanism when consecutive heartbeat failures occur (firmware fails to ack on heartbeat message). - Check also extended errors in the PCIe addr_dec interrupt information. - Rate limit the error messages that can be printed to dmesg log by userspace actions. - Firmware related fixes: - Handle requests from firmware to reserve device memory - Bug fixes and code cleanups: - constify the struct device_type usage in accel (accel_sysfs_device_minor). - Fix the PCI health check by reading uncached register. - Fix reporting of drain events. - Fix debugfs files permissions. - Fix calculation of DRAM BAR base address. ---------------------------------------------------------------- Avri Kehat (1): accel/habanalabs: fix debugfs files permissions Colin Ian King (1): accel/habanalabs/goya: remove redundant assignment to pointer 'input' Dani Liberman (3): accel/habanalabs/gaudi2: add interrupt affinity for user interrupts accel/habanalabs: remove call to deprecated function accel/habanalabs: fix error print Erick Archer (1): accel/habanalabs: use kcalloc() instead of kzalloc() Farah Kassabri (2): accel/habanalabs/gaudi2: move HMMU page tables to device memory accel/habanalabs: remove hop size from asic properties Koby Elbaz (1): accel/habanalabs: increase HL_MAX_STR to 64 bytes to avoid warnings Malkoot Khan (1): accel/habanalabs: Remove unnecessary braces from if statement Ofir Bitton (3): accel/habanalabs/gaudi2: drain event lacks rd/wr indication accel/habanalabs/hwmon: rate limit errors user can generate accel/habanalabs: modify pci health check Ricardo B.
