As promised in the basic wide planes support ([1]) here comes a series supporting 2*max_linewidth for all the planes. Note: Unlike v1 and v2 this series finally includes support for additional planes - having more planes than the number of SSPP blocks. Note: this iteration features handling of rotation and reflection of the wide plane. However rot90 is still not tested: it is enabled on sc7280 and it only supports UBWC (tiled) framebuffers, it was quite low on my priority list. [1] https://patchwork.freedesktop.org/series/99909/ Changes since v3: - Dropped the drm_atomic_helper_check_plane_noscale (Ville) - Reworked the scaling factor according to global value and then check if SSPP has scaler_blk later on. - Split drm_rect_fp_to_int from the rotation-related fix (Abhinav) Changes since v2: - Dropped the encoder-related parts, leave all resource allocation as is (Abhinav) - Significantly reworked the SSPP allocation code - Added debugging code to dump RM state in dri/N/state Changes since v1: - Fixed build error due to me missing one of fixups, it was left uncommitted. - Implementated proper handling of wide plane rotation & reflection. Dmitry Baryshkov (13): drm/msm/dpu: take plane rotation into account for wide planes drm/msm/dpu: use drm_rect_fp_to_int() drm/msm/dpu: move pstate->pipe initialization to dpu_plane_atomic_check drm/msm/dpu: drop virt_formats from SSPP subblock configuration drm/msm/dpu: move scaling limitations out of the hw_catalog drm/msm/dpu: split dpu_plane_atomic_check() drm/msm/dpu: move rot90 checking to dpu_plane_atomic_check_pipe() drm/msm/dpu: add support for virtual planes drm/msm/dpu: allow using two SSPP blocks for a single plane drm/msm/dpu: allow sharing SSPP between planes drm/msm/dpu: create additional virtual planes drm/msm/dpu: allow sharing of blending stages drm/msm/dpu: include SSPP allocation state into the dumped state drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 59 +- .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.c | 20 - .../gpu/drm/msm/disp/dpu1/dpu_hw_catalog.h | 8 - drivers/gpu/drm/msm/disp/dpu1/dpu_hw_sspp.h | 2 + drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 22 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.h | 4 + drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 675 +++++++++++++++--- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.h | 29 +- drivers/gpu/drm/msm/disp/dpu1/dpu_rm.c | 84 +++ drivers/gpu/drm/msm/disp/dpu1/dpu_rm.h | 28 + 10 files changed, 779 insertions(+), 152 deletions(-) -- 2.39.2
