Commit Message

Vinod Polimera March 3, 2022, 11:42 a.m. UTC
- Some DPU versions support inline rot90. It is supported only for
limited amount of UBWC formats.
- There are two versions of inline rotators, v1 (present on sm8250 and
sm7250) and v2 (sc7280). These versions differ in the list of supported
formats and in the scaler possibilities.

Changes in RFC:
- Rebase changes to the latest code base.
- Append rotation config variables with v2 and
remove unused variables.(Dmitry)
- Move pixel_ext setup separately from scaler3 config.(Dmitry)
- Add 270 degree rotation to supported rotation list.(Dmitry)

Changes in V2:
- Remove unused macros and fix indentation.
- Add check if 90 rotation is supported and add supported rotations to rot_cfg.

Just use u32 when in the kernel. It's shorter and is the same.

pipe_hw_caps->sblk is used multiple times. Make it into a local
variable? Also make this whole chunk into a function to reduce
indentation?

unsigned int i, num_formats;

or

Indent the above two lines one more time so that they don't align
exactly with DPU_DEBUG_PLANE.

Same alignment request. Also, put it on the same line as DPU_DEBUG_PLANE
so we can find it with a grep for that macro.

This would be smaller if

	rotation = pstate->rotation

replaced drm_rotation_simplify(). Please do that to minimize code
reviewer.

No. Please pass pre-scale config directly here, rather than reverting
the rotation.
You can safely pass drm_rect_height/_width of &pipe_cfg->src_rect to
this function.

I think we can move rot_supported to SSPP capabilities. Then you can
use drm_rotation simplify() unconditionally. And move the check
whether INLINE_ROTATION is support to the code below

Please move this code block to a separate function.
IOW
if (rotation & DRM_MODE_ROTATE_90) {
   ret = dpu_plane_check_inline_rotation(....);
   if (ret)
     return ret;

So... If inline rotation is not supported, pstate->rotation is rather
than simplified rotation. Is this expected? Probably not.

Slight hint: if you change this to:
unsigned int rotation =pstate->rotation;
you won't have to change the consequent lines.
