Hi Dave, Daniel. Habanalabs pull request for 6.7. It's a bit all over the place, a few uapi changes, mostly improvements and bug fixes. Notable things are the move to the accel subsystem in the code itself, meaning we removed the habanalabs class and the code to created device char and instead we are registering to accel. Also notable is moving some firmware interface files to include/linux/habanalabs. This is needed as a pre-requisite for upstreaming the Gaudi2 NIC drivers, which will include those files. Full details are in the signed tag. Thanks, Oded The following changes since commit 389af786f92ecdff35883551d54bf4e507ffcccb: Merge tag 'drm-intel-next-2023-09-29' of git://anongit.freedesktop.org/drm/drm-intel into drm-next (2023-10-04 13:55:19 +1000) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux.git tags/drm-habanalabs-next-2023-10-10 for you to fetch changes up to 4db74c0fdeb8138f6438d42a015c5dcdb2e6874c: accel/habanalabs/gaudi2: fix spmu mask creation (2023-10-09 12:37:24 +0300) ---------------------------------------------------------------- This tag contains habanalabs driver changes for v6.7. The notable changes are: - uAPI changes: - Expose tsc clock sampling to better sync clock information in profiler. - Enhance engine error reporting in the info ioctl. - Block access to the eventfd operations through the control device. - Disable the option of the user to register multiple times with the same offset for timestamp dump by the driver. If a user wants to use the same offset in the timestamp buffer for different interrupt, it needs to first de-register the offset. - When exporting dma-buf (for p2p), force the user to specify size/offset in multiples of PAGE_SIZE. This is instead of the driver doing the rounding to PAGE_SIZE, which has caused the driver to map more memory than was intended by the user. - New features and improvements: - Complete the move of the driver to the accel subsystem by removing the custom habanalabs class and major and registering to accel subsystem. - Move the firmware interface files to include/linux/habanalabs. This is a pre-requisite for upstreaming the NIC drivers of Gaudi (as they need to include those files). - Perform device hard-reset upon PCIe AXI drain event to prevent the failure from cascading to different IP blocks in the SoC. In secured environments, this is done automatically by the firmware. - Print device name when it is removed for better debuggability. - Add support for trace of dma map sgtable operations. - Optimize handling of user interrupts by splitting the interrupts to two lists. One list for fast handling and second list for handling with timestamp recording, which is slower. - Prevent double device hard-reset due to 2 adjacent H/W events. - Set device status 'malfunction' while in rmmod. - Firmware related fixes: - Extend preboot timeout because preboot loading might take longer than expected in certain cases. - Add a protection mechanism for the Event Queue. In case it is full, the firmware will be able to notify about it through a dedicated interrupt. - Perform device hard-reset in case scrubbing of memory has failed. - Bug fixes and code cleanups: - Small fixes of dma-buf handling in Gaudi2, such as handling an offset != 0, using the correct exported size, creation of sg table. - Fix spmu mask creation. - Fix bug in wait for cs completion for decoder workloads. - Cleanup Greco name from documentation. - Fix bug in recording timestamp during cs completion interrupt handling. - Fix CoreSight ETF configuration and flush logic. - Fix small bug in hpriv_list handling (the list that contains the private data per process that opens our device). ---------------------------------------------------------------- Ariel Suller (1): accel/habanalabs:
