Iff a buffer is created with a scanout flag, as a multiple of 64K, it can be used for CCS. This should fix the corruption issue, the changes to UMD will be only setting a multiple of 64K for CCS fb's. Untested, lets see if it gets through CI. :) Maarten Lankhorst (1): drm/xe: Align 64k scanout buffers physically when required Zbigniew Kempczyński (1): drm/xe: Use 64K pages for scanout buffers for Battlemage drivers/gpu/drm/xe/display/intel_fb_bo.c | 6 ++++++ drivers/gpu/drm/xe/xe_bo.c | 17 ++++++++++++++++- drivers/gpu/drm/xe/xe_device_types.h | 1 + drivers/gpu/drm/xe/xe_pci.c | 9 ++++++++- drivers/gpu/drm/xe/xe_vm.c | 4 +++- 5 files changed, 34 insertions(+), 3 deletions(-) -- 2.45.2
