[PATCH 1/4] drm/msm: Use drm_mode_vrefresh instead of mode->vrefresh

[PATCH 1/4] drm/msm: Use drm_mode_vrefresh instead of mode->vrefresh

[Sean Paul]

From: Sean Paul <seanpaul@chromium.org>

Use the drm_mode_vrefresh helper where we need refresh rate in case
vrefresh is empty.

[PATCH 3/4] drm/msm: dpu: Untangle frame_done timeout units

[Sean Paul]

From: Sean Paul <seanpaul@chromium.org>

There exists a bunch of confusion as to what the actual units of
frame_done is:

- The definition states it's in # of frames
- CRTC treats it like it's ms
- frame_done_timeout comment thinks it's Hz, but it stores ms
- frame_done timer is setup such that it _should_ be in frames, but the
  timeout is super long

So this patch tries to interpret what the driver really wants. I've
de-centralized the #define since the consumers are expecting different
units.

For crtc, we just use 60ms since that's what it was doing before.
Perhaps we could get fancy and scale with vrefresh, but that's for
another time.

For encoder, fix the comments and rename frame_done_timeout so it's
obvious what the units are. In practice, frame_done_timeout is really
just checked against 0 || !0, which I guess is why the units being wrong
didn't matter. I've also dropped the timeout from the previous 60 frames
to 5. That seems like more than enough time to give up on a frame, and
my guess is that no one intended for the timeout to _actually_ be 60
frames.

Nice cleanup!  Units make it much easier to read.

[PATCH 2/4] drm/msm: dpu: Simplify frame_done watchdog timeout calculation

[Sean Paul]

From: Sean Paul <seanpaul@chromium.org>

Instead of setting the timeout and then immediately reading it back
(along with the hand-rolled msecs_to_jiffies calculation), just
calculate it once and set it in both places at the same time.

For future cleanup: Is drm_enc->crtc a valid usage here?

[PATCH 4/4] drm/msm: dpu: Don't queue the frame_done watchdog for cursor

[Sean Paul]

From: Sean Paul <seanpaul@chromium.org>

In the case of an async/cursor update, we don't wait for the frame_done
event, which means handle_frame_done is never called, and the frame_done
watchdog isn't canceled. Currently, this results in a frame_done timeout
every time the cursor moves without a synchronous frame following it up
before the timeout expires. Since we don't wait for frame_done, and
don't handle it, we shouldn't modify the watchdog.

I think adding a todo to remove these fields and switch everone over to
the helpers would be useful. Recomputing is not going to hurt us I think
in modeset code (the one case where we do care is vblank constants, and
those are somewhere else), and would avoid all these bugs ...

Yeah, and to boot if vrefresh is populated, the function just returns it, so
it's quite safe (unless someone is relying on vrefresh == 0 as valid data, which
would be nice to weed out anyways).

I'll spin up a TODO patch, good suggestion.
