Adreno 840 GPU supports UBWC v6. Add support for this. Signed-off-by: Akhil P Oommen <[email protected]> --- << Trimmed the cover letter since b4 folds it into the single patch >>
This series adds the A8xx HWL along with Adreno 840 GPU support to the drm-msm driver. A8x is the next generation in the Adreno family, featuring a significant hardware design change. A major update to the design is the introduction of 'Slice' architecture. Slices are sort of mini-GPUs within the GPU which are more independent in processing Graphics and compute workloads. Also, in addition to the BV and BR pipe we saw in A7x, CP has more concurrency with additional pipes. The single pending patch in this series in now ready to pick up into the msm-next. --- Changes in v5: - Dropped merged patches - Rebased on top of msm-next tip - Link to v4: https://lore.kernel.org/r/[email protected] --- drivers/gpu/drm/msm/adreno/a8xx_gpu.c | 4 ++++ 1 file changed, 4 insertions(+) diff --git a/drivers/gpu/drm/msm/adreno/a8xx_gpu.c b/drivers/gpu/drm/msm/adreno/a8xx_gpu.c index 30de078e9dfd..5a320f5bde41 100644 --- a/drivers/gpu/drm/msm/adreno/a8xx_gpu.c +++ b/drivers/gpu/drm/msm/adreno/a8xx_gpu.c @@ -276,6 +276,10 @@ static void a8xx_set_ubwc_config(struct msm_gpu *gpu) u8 uavflagprd_inv = 2; switch (ubwc_version) { + case UBWC_6_0: + yuvnotcomptofc = true; + mode = 5; + break; case UBWC_5_0: amsbc = true; rgb565_predicator = true; --- base-commit: f185076da44c774241a16a82a7773ece3c1c607b change-id: 20250929-kaana-gpu-support-11d21c8fa1dc Best regards, -- Akhil P Oommen <[email protected]>
