Convert direct mode.vrefresh accesses to use drm_mode_vrefresh()
|
||||
----------------------------------------------------------------
|
||||
|
||||
drm_display_mode.vrefresh isn't guaranteed to be populated. As such, using it
|
||||
is risky and has been known to cause div-by-zero bugs. Fortunately, drm core
|
||||
has helper which will use mode.vrefresh if it's !0 and will calculate it from
|
||||
the timings when it's 0.
|
||||
|
||||
Use simple search/replace, or (more fun) cocci to replace instances of direct
|
||||
vrefresh access with a call to the helper. Check out

https://lists.freedesktop.org/archives/dri-devel/2019-January/205186.html for

inspiration.
|

Once all instances of vrefresh have been converted, remove vrefresh from

drm_display_mode to avoid future use.

Consolidate custom driver modeset properties
|
||||
--------------------------------------------
|
||||
|
||||
Before atomic modeset took place, many drivers where creating their own
|
||||
properties. Among other things, atomic brought the requirement that custom,
|
||||
driver specific properties should not be used.
|
||||
|
||||
For this task, we aim to introduce core helpers or reuse the existing ones
|
||||
if available:
|
||||
|
||||
A quick, unconfirmed, examples list.
|
||||
|
||||
Introduce core helpers:
|
||||
- audio (amdgpu, intel, gma500, radeon)
|
||||
- brightness, contrast, etc (armada, nouveau) - overlay only (?)
|
||||
- broadcast rgb (gma500, intel)
|
||||
- colorkey (armada, nouveau, rcar) - overlay only (?)
|
||||
- dither (amdgpu, nouveau, radeon) - varies across drivers
|
||||
- underscan family (amdgpu, radeon, nouveau)
|
||||
|
||||
Already in core:
|
||||
- colorspace (sti)
|
||||
- tv format names, enhancements (gma500, intel)
|
||||
- tv overscan, margins, etc. (gma500, intel)
|
||||
- zorder (omapdrm) - same as zpos (?)
