The intent is to move the GuC and HuC firmware images to the top of the address space. This portion is inaccessible during normal GuC operations and should be relatively safe to house both firmware images. By making the move we can re-enable the full gpu reset with GuC enabled. Placing the firmware images above GUC_GGTT_TOP was discussed previously here: https://patchwork.freedesktop.org/patch/273616/ Cc: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx> Cc: Daniele Ceraolo Spurio <daniele.ceraolospurio@xxxxxxxxx> Fernando Pacheco (4): drm/i915/uc: Rename uC firmware init function drm/i915/uc: Reserve upper range of GGTT drm/i915/uc: Place uC firmware in upper range of GGTT Revert "drm/i915/guc: Disable global reset" drivers/gpu/drm/i915/i915_gem.c | 2 + drivers/gpu/drm/i915/i915_gem_gtt.c | 25 +++++++- drivers/gpu/drm/i915/i915_gem_gtt.h | 1 + drivers/gpu/drm/i915/i915_reset.c | 3 - drivers/gpu/drm/i915/intel_guc.c | 9 ++- drivers/gpu/drm/i915/intel_guc.h | 11 ++++ drivers/gpu/drm/i915/intel_guc_fw.c | 45 +++++++++++--- drivers/gpu/drm/i915/intel_guc_fw.h | 3 + drivers/gpu/drm/i915/intel_huc.c | 72 +++++++++++++++++----- drivers/gpu/drm/i915/intel_huc.h | 4 ++ drivers/gpu/drm/i915/intel_huc_fw.c | 82 ++++++++++++++++++++---- drivers/gpu/drm/i915/intel_huc_fw.h | 3 + drivers/gpu/drm/i915/intel_uc.c | 39 ++++++++++-- drivers/gpu/drm/i915/intel_uc.h | 1 + drivers/gpu/drm/i915/intel_uc_fw.c | 96 ++++++++++++++++++++--------- drivers/gpu/drm/i915/intel_uc_fw.h | 15 ++++- 16 files changed, 329 insertions(+), 82 deletions(-) -- 2.21.0 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
