drm/xe/configfs: Don't expose survivability_mode if not applicable

2025-09-04T20:33:51Z

The survivability_mode attribute is applicable only for DGFX and platforms newer than BATTLEMAGE. Use .is_visible() hook to hide this attribute when above conditions are not met. Remove code that was trying to fix such configuration during the runtime.

drm/xe/xe_hw_error: Handle CSC Firmware reported Hardware errors

2025-08-26T14:11:34Z

Add support to handle CSC firmware reported errors. When CSC firmware errors are encoutered, a error interrupt is received by the GFX device as a MSI interrupt. Device Source control registers indicates the source of the error as CSC The HEC error status register indicates that the error is firmware reported Depending on the type of error, the error cause is written to the HEC Firmware error register. On encountering such CSC firmware errors, the graphics device is non-recoverable from driver context. The only way to recover from these errors is firmware flash. System admin/userspace is notified of the necessity of firmware flash with a combination of vendor-specific drm device edged uevent, dmesg logs and runtime survivability sysfs. It is the responsiblity of the consumer to verify all the actions and then trigger a firmware flash using tools like fwupd. $ udevadm monitor --property --kernel monitor will print the received events for: KERNEL - the kernel uevent KERNEL[754.709341] change /devices/pci0000:00/0000:00:01.0/0000:01:00.0/0000:02:01.0/0000:03:00.0/drm/card0 (drm) ACTION=change DEVPATH=/devices/pci0000:00/0000:00:01.0/0000:01:00.0/0000:02:01.0/0000:03:00.0/drm/card0 SUBSYSTEM=drm WEDGED=vendor-specific DEVNAME=/dev/dri/card0 DEVTYPE=drm_minor SEQNUM=5973 MAJOR=226 MINOR=0 Logs xe 0000:03:00.0: [drm] *ERROR* [Hardware Error]: Tile0 reported NONFATAL error 0x20000 xe 0000:03:00.0: [drm] *ERROR* [Hardware Error]: NONFATAL: HEC Uncorrected FW FD Corruption error reported, bit[2] is set xe 0000:03:00.0: Runtime Survivability mode enabled xe 0000:03:00.0: [drm] *ERROR* CRITICAL: Xe has declared device 0000:03:00.0 as wedged.

drm/xe: Set survivability mode before heci init

2025-03-21T18:48:22Z

Commit d40f275d96e8 ("drm/xe: Move survivability entirely to xe_pci") tried to follow the logic: initialize everything needed and if everything succeeds, set the flag that it's enabled. While it fixed some corner cases of those calls failing, it was wrong for setting the flag after the call to xe_heci_gsc_init(): that function does a different initialization for survivability mode. Fix that and add comments about this being done on purpose.
