[PATCH v2 3/8] drm: vkms: Replace hardcoded value of `vkms_composer.map` to DRM_FORMAT_MAX_PLANES
by Igor Torrente 25 Oct '21

25 Oct '21

The `map` vector at `vkms_composer` uses a hardcoded value to define its size. If someday the maximum number of planes increases, this hardcoded value can be a problem. This value is being replaced with the DRM_FORMAT_MAX_PLANES macro.

[PATCH v2 2/8] drm: vkms: Alloc the compose frame using vzalloc
by Igor Torrente 25 Oct '21

25 Oct '21

Currently, the memory to the composition frame is being allocated using the kzmalloc. This comes with the limitation of maximum size of one page size(which in the x86_64 is 4Kb and 4MB for default and hugepage respectively). Somes test of igt (e.g. kms_plane@pixel-format) uses more than 4MB when testing some pixel formats like ARGB16161616. This problem is addessed by allocating the memory using kvzalloc that circunvents this limitation.

[PATCH v2 00/11] drm/msm: Add Display Stream Compression Support
by Vinod Koul 25 Oct '21

25 Oct '21

Display Stream Compression (DSC) compresses the display stream in host which is later decoded by panel. This series enables this for Qualcomm msm driver. This was tested on Google Pixel3 phone which use LGE SW43408 panel. The changes include DSC data and hardware block enabling for DPU1 then support in encoder. We also add support in DSI and introduce required topology changes. In order for panel to set the DSC parameters we add dsc in drm_panel and set it from the msm driver. Complete changes which enable this for Pixel3 along with panel driver (not part of this series) and DT changes can be found at: git.linaro.org/people/vinod.koul/kernel.git pixel/dsc_v2 Comments welcome! Changes since v1: - Fix various issues spotted by kbuildbot - Rebase to v5.15-rc3 - Remove unused fields and duplicate defines - Enable DSC blocks only when DSC is enabled - remove sdm845 feature mask, use 0 - Check for DSC in hw_ctl Changes since RFC: - Drop the DT binding patch as we derive the configuration from panel - Drop the drm api patch as we no longer need it (use pps drm api) - Fix comments raised by Dimitry - Add dsc parameters calculation from downstream Vinod Koul (11): drm/msm/dsi: add support for dsc data drm/msm/disp/dpu1: Add support for DSC drm/msm/disp/dpu1: Add support for DSC in pingpong block drm/msm/disp/dpu1: Add DSC support in RM drm/msm/disp/dpu1: Add DSC for SDM845 to hw_catalog drm/msm/disp/dpu1: Don't use DSC with mode_3d drm/msm/disp/dpu1: Add DSC support in hw_ctl drm/msm/disp/dpu1: Add support for DSC in encoder drm/msm/disp/dpu1: Add support for DSC in topology drm/msm/dsi: Add support for DSC configuration drm/msm/dsi: Pass DSC params to drm_panel drivers/gpu/drm/msm/Makefile | 1 + drivers/gpu/drm/msm/disp/dpu1/dpu_encoder.c | 155 +++++++++- .../gpu/drm/msm/disp/dpu1/dpu_encoder_phys.h | 11 + .../drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c | 2 + .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 20 ++ .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 13 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.c | 17 +- drivers/gpu/drm/msm/disp/dpu1/dpu_hw_ctl.h | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.c | 210 ++++++++++++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.h | 77 +++++ drivers/gpu/drm/msm/disp/dpu1/dpu_hw_mdss.h | 13 + .../gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.c | 32 +++ .../gpu/drm/msm/disp/dpu1/dpu_hw_pingpong.h | 14 + drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 1 + drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c | 61 ++++ drivers/gpu/drm/msm/disp/dpu1/dpu_rm.h | 1 + drivers/gpu/drm/msm/dsi/dsi.xml.h | 10 + drivers/gpu/drm/msm/dsi/dsi_host.c | 269 +++++++++++++++++- drivers/gpu/drm/msm/msm_drv.h | 18 ++ include/drm/drm_panel.h | 7 + 20 files changed, 928 insertions(+), 6 deletions(-) create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.c create mode 100644 drivers/gpu/drm/msm/disp/dpu1/dpu_hw_dsc.h -- 2.31.1

[PATCH v3 0/5] CMDQ refinement of Mediatek DRM driver
by jason-jh.lin 25 Oct '21

25 Oct '21

These refinements include using standard mailbox callback interface, timeout detection, and a fixed cmdq_handle. Change in v3: 1. Revert "drm/mediatek: clear pending flag when cmdq packet is done" and add it after the CMDQ refinement pathes. 2. Change the remove of struct cmdq_client to remove the pointer of struct cmdq_client. 3. Fix pkt buf alloc once but free many times. Changes in v2: 1. Define mtk_drm_cmdq_pkt_create() and mtk_drm_cmdq_pkt_destroy() when CONFIG_MTK_CMDQ is reachable.

[PATCH v6 1/3] pwm: Introduce single-PWM of_xlate function
by Bjorn Andersson 25 Oct '21

25 Oct '21

The existing pxa driver and the upcoming addition of PWM support in the TI sn565dsi86 DSI/eDP bridge driver both has a single PWM channel and thereby a need for a of_xlate function with the period as its single argument. Introduce a common helper function in the core that can be used as of_xlate by such drivers and migrate the pxa driver to use this.

[PATCH -next] drm: Small optimization to intel_dp_mst_atomic_master_trans_check
by He Ying 25 Oct '21

25 Oct '21

If we want to return from for_each_intel_connector_iter(), one way is calling drm_connector_list_iter_end() before returning to avoid memleak. The other way is just breaking from the bracket and then returning after the outside drm_connector_list_iter_end(). Obviously, the second way makes code smaller and more clear. Apply it to the function intel_dp_mst_atomic_master_trans_check().

Regression with mainline kernel on rpi4
by Sudip Mukherjee 25 Oct '21

25 Oct '21

Hi All, Our last night's test on rpi4 had a nasty trace. The test was with 7c636d4d20f8 ("Merge tag 'dt-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc"). Previous test was on 9e9fb7655ed5 ("Merge tag 'net-next-5.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next") and it did not have this trace.
