drm/i915: Add a kludge for DSL incrementing too late and ISR not working

On pre-PCH platforms ISR doesn't seem to be an actual ISR, at least as
far as display interrupts are concerned. Instead it sort of looks like
some ISR bits just directly reflect the corresponding bit from PIPESTAT.
The bit appears in the ISR only if the PIPESTAT interrupt is enabled. So
in that sense it sort of looks a bit like the south interrupt scheme on
PCH platforms. So it goes something a bit like this:
PIPESTAT.status & PIPESTAT.enable -> ISR -> IMR -> IIR -> IER -> actual
interrupt

In any case that means the intel_pipe_in_vblank_locked() doesn't actually
work for pre-PCH platforms. As a last resort, add a similar kludge as radeon
has that fixes things up if we got called from the vblank interrupt,
but the scanline counter value indicates that we're not quite there yet.
We know that the scanline counter increments at hsync but is otherwise
accurate, so we can limit the kludge to the line just prior to vblank
start, instead of the relative distance that radeon uses.

drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos()

i915 doesn't need this kludge for most platforms. Although we do
appear to need something similar on certain platforms, but we can
be more accurate when we apply the adjustment since we know exactly
why the scanline counter doesn't always quite match the vblank
status.

Also the current code doesn't handle interlaced modes correctly,

So let's just move the current code to radeon_get_crtc_scanoutpos()

drm/i915: Fix scanoutpos calculations for interlaced modes

The scanline counter counts lines in the current field, not the entire
frame. But the crtc_ timings are the values for the entire frame. Divide
the vertical timings by 2 to make them match the scanline counter.

The rounding was carefully chosen to make it do the right thing wrt. the
observed scanline counter and ISR vblank bit behaviour.

drm: Change {pixel,line,frame}dur_ns from s64 to int

Using s64 for the timestamping constants is wasteful. Signed 32bit
integers get us a range of over +-2 seconds. Presuming that no-one
wants to a vrefresh rate less than 0.5, we can switch to using int
for the timestamping constants. We save a few bytes in drm_crtc and
avoid a bunch of 64bit math.

10 years agodrm: Use crtc_clock in drm_calc_timestamping_constants()

drm_calc_timestamping_constants() computes the pixel/line/frame

clock is in mode->crtc_clock, so we need to use that instead of
mode->clock.

stereo modes.
