[Intel-gfx] [PATCH v2 0/5] drm/i915: extract vblank/scanline code to a separate file

[Jani Nikula]

Basically just https://patchwork.freedesktop.org/series/111854/ with the
two controversial patches dropped for now.

BR,
Jani.

Jani Nikula (5):
  drm/i915/irq: split out vblank/scanline code to intel_vblank.[ch]
  drm/i915/display: move more scanline functions to intel_vblank.[ch]
  drm/i915/display: use common function for checking scanline is moving
  drm/i915/vblank: use intel_de_read()
  drm/i915/vblank: add and use intel_de_read64_2x32() to read vblank
    counter

[Intel-gfx] [PATCH v2 1/5] drm/i915/irq: split out vblank/scanline code to intel_vblank.[ch]

[Jani Nikula]

The vblank/scanline code is fairly isolated in i915_irq.c. Split it out
to new intel_vblank.[ch].

[Intel-gfx] [PATCH v2 3/5] drm/i915/display: use common function for checking scanline is moving

[Jani Nikula]

cpt_verify_modeset() is roughly the same as
intel_wait_for_pipe_scanline_moving(). Assume it's close enough.

[Intel-gfx] [PATCH v2 5/5] drm/i915/vblank: add and use intel_de_read64_2x32() to read vblank counter

[Jani Nikula]

Add intel_de_read64_2x32() wrapper for the uncore version of the same,
and use it to read the high and low frame registers. Avoid duplicating
code for existing helpers.

The slight functional difference is checking that the entire high
register remains the same across two reads, instead of just the part
we're interested in. This should be of no consequence. (Unless those
bits function as a PRNG.)
