[PATCH] drm: handle kernel fences in drm_gem_plane_helper_prepare_fb v2
by Christian König 28 Apr '22

28 Apr '22

drm_gem_plane_helper_prepare_fb() was using drm_atomic_set_fence_for_plane() which ignores all implicit fences when an explicit fence is already set. That's rather unfortunate when the fb still has a kernel fence we need to wait for to avoid presenting garbage on the screen. So instead update the fence in the plane state directly. While at it also take care of all potential GEM objects and not just the first one. Also remove the now unused drm_atomic_set_fence_for_plane() function, new drivers should probably use the atomic helpers directly. v2: improve kerneldoc, use local variable and num_planes, WARN_ON_ONCE on missing planes.

[PATCH] dma-buf: add the name field to the table header
by Yuanzheng Song 28 Apr '22

28 Apr '22

'cat /sys/kernel/debug/dma_buf/bufinfo' will print the Dma-buf Objects' information when the CONFIG_DEBUG_FS=y. However, the printed table header information does not contain the name field. So we need to add the name field to the table header and use the '<none>' to replace the empty buf_obj->name.

[PATCH v2] drm/display: Select DP helper for DRM_DP_AUX_CHARDEV and DRM_DP_CEC
by Javier Martinez Canillas 28 Apr '22

28 Apr '22

The DRM_DP_AUX_CHARDEV and DRM_DP_CEC Kconfig symbols enable code that use DP helper functions, that are only present if CONFIG_DRM_DISPLAY_DP_HELPER is also enabled. But these don't select the DRM_DISPLAY_DP_HELPER symbol, meaning that it is possible to enable any of them without CONFIG_DRM_DISPLAY_DP_HELPER. That will lead to the following linking errors with the mentioned config: LD vmlinux.o MODPOST vmlinux.symvers MODINFO modules.builtin.modinfo GEN modules.builtin LD .tmp_vmlinux.kallsyms1 KSYMS .tmp_vmlinux.kallsyms1.S AS .tmp_vmlinux.kallsyms1.S LD .tmp_vmlinux.kallsyms2 KSYMS .tmp_vmlinux.kallsyms2.S AS .tmp_vmlinux.kallsyms2.S LD vmlinux SYSMAP System.map SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image MODPOST modules-only.symvers ERROR: modpost: "drm_dp_dpcd_write" [drivers/gpu/drm/display/drm_display_helper.ko] undefined!

Hi Dave & Daniel, Here goes drm-intel-fixes PR for v5.18-rc5. Fixes for backlight control on XMG Core 15 e21 (#5284, regression since 5.15) and black display plane on Acer One AO532h. Then two smaller display fixes picked up by tooling.

[PATCH 0/2] Initial GuC firmware release for DG2
by John.C.Harrison＠Intel.com 28 Apr '22

28 Apr '22

From: John Harrison <John.C.Harrison(a)Intel.com> Add GuC firmware for DG2. Note that an older version of this patch exists in the CI topic branch. Hence this set includes a revert of that patch before applying the new version. When merging, the revert would simply be dropped and the corresponding patch in the topic branch would also be dropped.

[PATCH 0/2] i915: Turn on compute engine support
by Matt Roper 28 Apr '22

28 Apr '22

Now that the necessary GuC-based hardware workarounds have landed, we're finally ready to actually enable compute engines for use by userspace. All of the "under-the-hood" heavy lifting already landed a while back in other series so all that remains now is to add I915_ENGINE_CLASS_COMPUTE to the uapi enum and add the CCS engines to the engine lists for the Xe_HP SDV and DG2. Userspace (both Mesa and compute drivers) are linked in the ABI patch. Existing IGT tests (e.g., i915_hangman) provide test coverage for general engine behavior since compute engines should follow the same general rules as other engines. We've also recently added some additional subtests like igt@gem_reset_stats@shared-reset-domain to cover the user-visible impacts of the compute engines sharing the same hardware reset domain as the render engine. Cc: Lucas De Marchi <lucas.demarchi(a)intel.com> Daniele Ceraolo Spurio (1): drm/i915: Xe_HP SDV and DG2 have up to 4 CCS engines Matt Roper (1): drm/i915/xehp: Add compute engine ABI drivers/gpu/drm/i915/gt/intel_engine_user.c | 2 +- drivers/gpu/drm/i915/gt/intel_gt.c | 1 + drivers/gpu/drm/i915/i915_drm_client.c | 1 + drivers/gpu/drm/i915/i915_drm_client.h | 2 +- drivers/gpu/drm/i915/i915_pci.c | 6 +- include/uapi/drm/i915_drm.h | 62 +++++++++++++++++++-- 6 files changed, 64 insertions(+), 10 deletions(-) -- 2.35.1
