2024-02-28Revert "drm/msm/dp: use drm_bridge_hpd_notify() to report HPD status changes"Dmitry Baryshkov
This reverts commit e467e0bde881 ("drm/msm/dp: use drm_bridge_hpd_notify() to report HPD status changes"). The commit changed the way how the MSM DP driver communicates HPD-related events to the userspace. The mentioned commit made some of the HPD events being reported earlier. This way userspace starts poking around. It interacts in a bad way with the dp_bridge_detect and the driver's state machine, ending up either with the very long delays during hotplug detection or even inability of the DP driver to report the display as connected. A proper fix will involve redesigning of the HPD handling in the MSM DP driver. It is underway, but it will be intrusive and can not be thought about as a simple fix for the issue. Thus, revert the offending commit.

2024-02-15drm/msm: Wire up tlb opsRob Clark
The brute force iommu_flush_iotlb_all() was good enough for unmap, but in some cases a map operation could require removing a table pte entry to replace with a block entry. This also requires tlb invalidation. Missing this was resulting an obscure iova fault on what should be a valid buffer address. Thanks to Robin Murphy for helping me understand the cause of the fault.

2024-02-01Revert "drm/msm/gpu: Push gpu lock down past runpm"Rob Clark
This reverts commit abe2023b4cea192ab266b351fd38dc9dbd846df0. Changing the locking order means that scheduler/msm_job_run() can race with the recovery kthread worker, with the result that the GPU gets an extra runpm get when we are trying to power it off. Leaving the GPU in an unrecovered state. I'll need to come up with a different scheme for appeasing lockdep.

2024-02-01drm/msm/a6xx: set highest_bank_bit to 13 for a610Dmitry Baryshkov
During the testing of Gnome on Qualcomm Robotics platform screen corruption has been observed. Lowering GPU's highest_bank_bit from 14 to 13 seems to fix the screen corruption. Note, the MDSS and DPU drivers use HBB=1 (which maps to the highest_bank_bit = 14). So this change merely works around the UBWC swizzling issue on this platform until the real cause is found.

Make necessary changes in dpu_hw_ctl to support CDM programming. changes in v3: - drop unused cdm_active as reported by kbot - retained the R-b as its a trivial change changes in v2: - remove unused empty line - pass in cdm_num to update_pending_flush_cdm() Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/oe-kbuild-all/202312102047.S0I69pCs-lkp@intel.com/ Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/571829/ Link: https://lore.kernel.org/r/20231212205254.12422-11-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
2023-12-14drm/msm/dpu: add support to allocate CDM from RMAbhinav Kumar
