[RFC,v2,00/13] drm/msm/dpu: support virtual wide planes

Message

Dmitry Baryshkov March 21, 2023, 1:18 a.m. UTC

As promised in the basic wide planes support ([1]) here comes a series
supporting 2*max_linewidth for all the planes.

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.

Note#2: to simplify the dpu_plane_virtual_assign_resources(), which
already becomes big enough, I stripped support for sharing the SSPP
across two planes (doubling amount of planes available to some of
compositors/applications). I plan to get back to this topic once this
series lands.

Dependencies: msm-next + msm-fixes, [1], [2]

[1] https://patchwork.freedesktop.org/series/99909/

[2] https://patchwork.freedesktop.org/series/113423/

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/atomic-helper: split not-scaling part of
    drm_atomic_helper_check_plane_state
  drm/msm/dpu: take plane rotation into account for wide planes

  drm/msm/dpu: remove unused fields from dpu_encoder_virt
  drm/msm/dpu: get rid of struct dpu_rm_requirements
  drm/msm/dpu: switch RM to use crtc_id rather than enc_id for
    allocation
  drm/msm/dpu: move resource allocation to CRTC
  drm/msm/dpu: fill CRTC resources in dpu_crtc.c
  drm/msm/dpu: move pstate->pipe initialization to
    dpu_plane_atomic_check
  drm/msm/dpu: add list of supported formats to the DPU caps
