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.
