Code Issues Releases Packages Activity

This tag contains habanalabs driver and accel changes for v6.9.

Browse source 
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.
