https://git.shady.money/linux/atom?h=v6.162025-04-08T20:48:14Zdrm/amdgpu: Disable ACA on VFs2025-04-08T20:48:14ZVictor Skvortsovvictor.skvortsov@amd.com2025-04-02T21:35:56Zurn:sha1:3394069e7de984ea3a4c2c68bf69b65f1c0aa658
VFs query RAS error counts directly from host with
AMDGPU_RAS_VIRT_ERROR_COUNT_QUERY. When ACA is enabled,
an unusable aca_sysfs is created rather than amdgpu_ras_sysfs_create()
Likewise, VFs depend on host support to query CPERs, rather than ACA component.
