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)"

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. Reviewed-by: Christian König Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

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.

drm: Don't include in

2016-12-18T10:59:29+00:00

used to define most of the in-kernel KMS API. It has now been split into separate files for each object type, but still includes most other KMS headers to avoid breaking driver compilation. As a step towards fixing that problem, remove the inclusion of from and include it instead where appropriate. Also remove the forward declarations of the drm_encoder and drm_encoder_helper_funcs structures from as they're not needed in the header. now has to include and contain a forward declaration of struct drm_encoder in order to allow including it as the first header in a compilation unit.
