Hi all,
Very minor cleanups from Neil's review, and a minimal rebase because nouveau
changed something. Otherwise unchanged.
Still would like an ack from Ville/Mario before merging.
Thanks, Daniel
Daniel Vetter (5):
drm/vblank: Switch drm_driver->get_vblank_timestamp to return a bool
drm/vblank: Switch to bool in_vblank_irq in get_vblank_timestamp
drm/vblank: Add FIXME comments about moving the vblank ts hooks
drm/vblank: drop the mode argument from
drm_calc_vbltimestamp_from_scanoutpos
drm/vblank: Lock down vblank->hwmode more

There's really no reason for anything more:
- Calling this while the crtc vblank stuff isn't set up is a driver
bug. Those places alrready DRM_ERROR.
- Calling this when the crtc is off is either a driver bug (calling
drm_crtc_handle_vblank at the wrong time) or a core bug (for
anything else). Again, we DRM_ERROR.
- EINVAL is checked at higher levels already, and if we'd use struct
drm_crtc * instead of (dev, pipe) it would be real obvious that
those are again core bugs.
The only valid failure mode is crap hardware that couldn't sample a
useful timestamp, to ask the core to just grab a not-so-accurate
timestamp. Bool is perfectly fine for that.
v2: Also fix up the one caller, I lost that in the shuffling (Jani).
v3: Fixup commit message (Neil).

It's overkill to have a flag parameter which is essentially used just
as a boolean. This takes care of core + adjusting drivers.
Adjusting the scanout position callback is a bit harder, since radeon
also supplies it's own driver-private flags in there.

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).

In the previous patch we've implemented hwmode tracking a la i915 for
the vblank timestamp calculations. But that was just the basic
semantics, i915 has some nice sanity checks to make sure we keep
getting this right. Move them over too.

Shouldn't we do this in drm_crtc_vblank_reset() as well?
Hmm. Except we call that after drm_calc_timestamping_constants(). I
guess we should be able to move the reset() into
intel_modeset_readout_hw_state(). And possibly move the vblank_on()
call as well?

Yeah, it'd be nice to clean this stuff up some more, but there's also the
problem that legacy and new drivers callc drm_calc_timestamping_constants
at opposite ends of the modeset sequence. Doing more here is a bunch more
work, maybe for the next patche series ...
I don't think we need to call it in _reset, at least at boot-up it should
be 0 already. And for s/r we already shut down the pipe on suspend, so
it's gone through this here.
With the _ONCE nit address (and the build breakage I've introduced in this
version fixed), ack from you on the entire series?
Thanks, Daniel

Hmm. Indeed that seems like it should cover it.

It's overkill to have a flag parameter which is essentially used just
as a boolean. This takes care of core + adjusting drivers.
Adjusting the scanout position callback is a bit harder, since radeon
also supplies it's own driver-private flags in there.
v2: Fixup misplaced hunks (Neil).
v3: kbuild says v1 was better ...
