7 daysdrm/amd/display: Fix DP audio DTO1 clock source on DCE 6.Timur Kristóf1-15/+6
On DCE 6, DP audio was not working. However, it worked when an HDMI monitor was also plugged in. Looking at dce_aud_wall_dto_setup it seems that the main difference is that we use DTO1 when only DP is plugged in. When programming DTO1, it uses audio_dto_source_clock_in_khz which is set from get_dp_ref_freq_khz The dce60_get_dp_ref_freq_khz implementation looks incorrect, because DENTIST_DISPCLK_CNTL seems to be always zero on DCE 6, so it isn't usable. I compared dce60_get_dp_ref_freq_khz to the legacy display code, specifically dce_v6_0_audio_set_dto, and it turns out that in case of DCE 6, it needs to use the display clock. With that, DP audio started working on Pitcairn, Oland and Cape Verde. However, it still didn't work on Tahiti. Despite having the same DCE version, Tahiti seems to have a different audio device. After some trial and error I realized that it works with the default display clock as reported by the VBIOS, not the current display clock. The patch was tested on all four SI GPUs: * Pitcairn (DCE 6.0) * Oland (DCE 6.4) * Cape Verde (DCE 6.0) * Tahiti (DCE 6.0 but different) The testing was done on Samsung Odyssey G7 LS28BG700EPXEN on each of the above GPUs, at the following settings: * 4K 60 Hz * 1080p 60 Hz * 1080p 144 Hz Acked-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Rodrigo Siqueira <siqueira@igalia.com> Signed-off-by: Timur Kristóf <timur.kristof@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 645cc7863da5de700547d236697dffd6760cf051) Cc: stable@vger.kernel.org
7 daysdrm/amd/display: Fix fractional fb divider in set_pixel_clock_v3Timur Kristóf1-1/+1
For later VBIOS versions, the fractional feedback divider is calculated as the remainder of dividing the feedback divider by a factor, which is set to 1000000. For reference, see: - calculate_fb_and_fractional_fb_divider - calc_pll_max_vco_construct However, in case of old VBIOS versions that have set_pixel_clock_v3, they only have 1 byte available for the fractional feedback divider, and it's expected to be set to the remainder from dividing the feedback divider by 10. For reference see the legacy display code: - amdgpu_pll_compute - amdgpu_atombios_crtc_program_pll This commit fixes set_pixel_clock_v3 by dividing the fractional feedback divider passed to the function by 100000.

When getting the number of connectors, the VBIOS reports the number of valid indices, but it doesn't say which indices are valid, and not every valid index has an actual connector.

7 daysdrm/amd/display: Adjust DCE 8-10 clock, don't overclock by 15%Timur Kristóf1-7/+5
Adjust the nominal (and performance) clocks for DCE 8-10, and set them to 625 MHz, which is the value used by the legacy display code in amdgpu_atombios_get_clock_info. This was tested with Hawaii, Tonga and Fiji. These GPUs can output 4K 60Hz (10-bit depth) at 625 MHz. The extra 15% clock was added as a workaround for a Polaris issue which uses DCE 11, and should not have been used on DCE 8-10 which are already hardcoded to the highest possible display clock. Unfortunately, the extra 15% was mistakenly copied and kept even on code paths which don't affect Polaris. This commit fixes that and also adds a check to make sure not to exceed the maximum DCE 8-10 display clock.

This reverts commit 515986100d176663d0a03219a3056e4252f729e6. The dma_buf field in struct drm_gem_object is not stable over the object instance's lifetime. The field becomes NULL when user space releases the final GEM handle on the buffer object. This resulted in a NULL-pointer deref. Workarounds in commit 5307dce878d4 ("drm/gem: Acquire references on GEM handles for framebuffers") and commit f6bfc9afc751 ("drm/framebuffer: Acquire internal references on GEM handles") only solved the problem partially. They especially don't work for buffer objects without a DRM framebuffer associated. Hence, this revert to going back to using .import_attach->dmabuf.

[Why] A null pointer dereference vulnerability exists in the AMD display driver's (DC module) cleanup function dc_destruct(). When display control context (dc->ctx) construction fails (due to memory allocation failure), this pointer remains NULL. During subsequent error handling when dc_destruct() is called, there's no NULL check before dereferencing the perf_trace member (dc->ctx->perf_trace), causing a kernel null pointer dereference crash. [How] Check if dc->ctx is non-NULL before dereferencing.

2025-08-04drm/amd/display: Add primary plane to commits for correct VRR handlingMichel Dänzer1-0/+9
amdgpu_dm_commit_planes calls update_freesync_state_on_stream only for the primary plane. If a commit affects a CRTC but not its primary plane, it would previously not trigger a refresh cycle or affect LFC, violating current UAPI semantics. Fixes e.g. atomic commits affecting only the cursor plane being limited to the minimum refresh rate. Don't do this for the legacy cursor ioctls though, it would break the UAPI semantics for those.

2025-08-04drm/amdgpu: Retain job->vm in amdgpu_job_prepare_jobYuanShang1-7/+0
The field job->vm is used in function amdgpu_job_run to get the page table re-generation counter and decide whether the job should be skipped. Specifically, function amdgpu_vm_generation checks if the VM is valid for this job to use. For instance, if a gfx job depends on a cancelled sdma job from entity vm->delayed, then the gfx job should be skipped.

2025-08-04drm/amd/display: Fix DCE 6.0 and 6.4 PLL programming.Timur Kristóf2-14/+25
Apparently, both DCE 6.0 and 6.4 have 3 PLLs, but PLL0 can only be used for DP. Make sure to initialize the correct amount of PLLs in DC for these DCE versions and use PLL0 only for DP. Also, on DCE 6.0 and 6.4, the PLL0 needs to be powered on at initialization as opposed to DCE 6.1 and 7.x which use a different clock source for DFS. The following functions were used as reference from the old radeon driver implementation of DCE 6.x: - radeon_atom_pick_pll - atombios_crtc_set_disp_eng_pll Reviewed-by: Rodrigo Siqueira <siqueira@igalia.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Timur Kristóf <timur.kristof@gmail.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> (cherry picked from commit 35222b5934ec8d762473592ece98659baf6bc48e) Cc: stable@vger.kernel.org
