* [PATCH 3/3] drm/i915: Fix frame start delay programming
@ 2019-10-24 12:21 ` Ville Syrjala
0 siblings, 0 replies; 22+ messages in thread
From: Ville Syrjala @ 2019-10-24 12:21 UTC (permalink / raw)
To: intel-gfx
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Currently we're blindly poking at the frame start delay bits
in PIPECONF when trying to sanitize the hardware state. Those
bits decided to move elsewhere on HSW, so on many platforms
we're not doing anything at all here. Also we're forgetting
about the PCH transcoder entirely.
Add all the bit definitions for the various homes these bits
have had throughout the years, and reset them all to zero.
However I'm not entirely sure this is a safe thing to do. If
not I guess we'd want full readout+statecheck for this stuff.
For now let's stick to the current logic and hope for the
best.

* [Intel-gfx] [PATCH 3/3] drm/i915: Fix frame start delay programming
@ 2019-10-24 12:21 ` Ville Syrjala
0 siblings, 0 replies; 22+ messages in thread
From: Ville Syrjala @ 2019-10-24 12:21 UTC (permalink / raw)
To: intel-gfx
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
Currently we're blindly poking at the frame start delay bits
in PIPECONF when trying to sanitize the hardware state. Those
bits decided to move elsewhere on HSW, so on many platforms
we're not doing anything at all here. Also we're forgetting
about the PCH transcoder entirely.
Add all the bit definitions for the various homes these bits
have had throughout the years, and reset them all to zero.
However I'm not entirely sure this is a safe thing to do. If
not I guess we'd want full readout+statecheck for this stuff.
For now let's stick to the current logic and hope for the
best.

Is there any reason not to let it be set at 0.
Overall, I looked at the register and bit definitions for various platforms and this looks
a very reasonable change rectifying the frame start delay programming.
However I am not sure if for all platforms 0 will be the preferred value. If the default values
of these bits are 0 in hardware register (or the BIOS set them at 0 itself), this should
work seamlessly. Only caveat will be if the defaults are not 0 on all platforms, we may have
issues.
Good way to figure this out I guess is our CI results. So if the CI passes, this is

Is there any reason not to let it be set at 0.
Overall, I looked at the register and bit definitions for various platforms and this looks
a very reasonable change rectifying the frame start delay programming.
However I am not sure if for all platforms 0 will be the preferred value. If the default values
of these bits are 0 in hardware register (or the BIOS set them at 0 itself), this should
work seamlessly. Only caveat will be if the defaults are not 0 on all platforms, we may have
issues.
Good way to figure this out I guess is our CI results. So if the CI passes, this is

Default is 0, but supposedly some VBIOSen have left other values
in there for whatever reason. Or else we probably wouldn't have this
code to sanitize things.
I *may* want to try bumping this to 3 across the board to give
gamma programming more breathing room during the vblank, but I'm
not sure that's entirely safe to do. Hence I started with just
cleaning up the current mess.
IIRC there was also some obnoxious workaround on LVDS+IBX (or maybe
it was CPT) that would require some extra handling if we were to
program this to some non-zero value.

Default is 0, but supposedly some VBIOSen have left other values
in there for whatever reason. Or else we probably wouldn't have this
code to sanitize things.
I *may* want to try bumping this to 3 across the board to give
gamma programming more breathing room during the vblank, but I'm
not sure that's entirely safe to do. Hence I started with just
cleaning up the current mess.
IIRC there was also some obnoxious workaround on LVDS+IBX (or maybe
it was CPT) that would require some extra handling if we were to
program this to some non-zero value.
