drm: amd: remove dead code and pointless local lut storage

2017-08-04T09:35:15+00:00

The redundant fb helpers .load_lut, .gamma_set and .gamma_get are
no longer used. Remove the dead code and hook up the crtc .gamma_set
to use the crtc gamma_store directly instead of duplicating that
info locally.

drm/vblank: drop the mode argument from drm_calc_vbltimestamp_from_scanoutpos

2017-05-10T08:21:31+00:00

If we restrict this helper to only kms drivers (which is the case) we
can look up the correct mode easily ourselves. But it's a bit tricky:

- All legacy drivers look at crtc->hwmode. But that is updated already
  at the beginning of the modeset helper, which means when we disable
  a pipe. Hence the final timestamps might be a bit off. But since
  this is an existing bug I'm not going to change it, but just try to
  be bug-for-bug compatible with the current code. This only applies
  to radeon&amdgpu.

- i915 tries to get it perfect by updating crtc->hwmode when the pipe
  is off (i.e. vblank->enabled = false).

- All other atomic drivers look at crtc->state->adjusted_mode. Those
  that look at state->requested_mode simply don't adjust their mode,
  so it's the same. That has two problems: Accessing crtc->state from
  interrupt handling code is unsafe, and it's updated before we shut
  down the pipe. For nonblocking modesets it's even worse.

For atomic drivers try to implement what i915 does. To do that we add
a new hwmode field to the vblank structure, and update it from
drm_calc_timestamping_constants(). For atomic drivers that's called
from the right spot by the helper library already, so all fine. But
for safety let's enforce that.

For legacy driver this function is only called at the end (oh the
fun), which is broken, so again let's not bother and just stay
bug-for-bug compatible.

The  benefit is that we can use drm_calc_vbltimestamp_from_scanoutpos
directly to implement ->get_vblank_timestamp in every driver, deleting
a lot of code.

v2: Completely new approach, trying to mimick the i915 solution.

v3: Fixup kerneldoc.

v4: Drop the WARN_ON to check that the vblank is off, atomic helpers
currently unconditionally call this. Recomputing the same stuff should
be harmless.

v5: Fix typos and move misplaced hunks to the right patches (Neil).

v6: Undo hunk movement (kbuild).

Revert "drm/amdgpu: Refactor flip into prepare submit and submit. (v3)"

2017-05-01T15:21:42+00:00

This reverts commit cb341a319f7e66f879d69af929c3dadfc1a8f31e.

The purpose of the refactor was for amdgpu_crtc_prepare/submit_flip to
be used by the DC code, but that's no longer the case.

drm/amdgpu: Refactor flip into prepare submit and submit. (v3)

2017-01-27T16:13:31+00:00

Make pflip atomic friendly. Split the fuinction into
whatever can fail part and the actual flip submit part.
Call the pre-submit function before atomic states
are swapped so in case of error we can fail the
IOCTL.

v2:
Update due to  target_vblank code change.
Fix identetation.
Change return type for amdgpu_crtc_submit_flip to void
v3: agd: fix formatting
