Subject: [PATCH] kms:sunxi: add engine->crtc_mode_set() hook
|
||||
|
||||
This exposes both shortcomings in universal planes, and the superfluous
|
||||
intermediate structure of _engine.
|
||||
|
||||
Our backends are half the conceptual old-skool style CRTC, and half the
|
||||
sequencer/composer. It does not need to have any layer enabled or any
|
||||
buffer attached to do something useful, it can just show a background
|
||||
colour. Our 4 main layers are fully independent and can be ordered
|
||||
(almost) at will. There is no primary layer.
|
||||
|
||||
Universal planes still asume that there is a primary layer. And also do
|
||||
limited checking on whether this actually true.
|
||||
|
||||
The sun4i driver has, for some reason, an _engine struct in between,
|
||||
that serves no purpose other than to provide separation where no
|
||||
separation is needed, and it is clear in several cases that this
|
||||
separation has holes in it. It also is a psychological barrier for
|
||||
exposing things as the hardware sees it.
|
||||
|
||||
So instead of quickly bolting up some code to set the crtc width and
|
||||
height in the backend, it was deferred to setting the primary plane.
|
||||
|
||||
So while KMS assumes that there is a primary plane, it never enforces
|
||||
the primary plane to be the same dimensions as the CRTC.
|
||||
|
||||
So one is able to set the faux primary plane to whatever dimensions one
|
||||
likes, which then has the backend set to those dimensions, which then
|
||||
trips up our whole setup...
|
||||
|
||||
A very avoidable problem, on multiple fronts.
|
||||
|
||||
Also, we set interlacing with _every_ plane format set. This while this
|
||||
conceptually belongs to the CRTC. The fact that the information comes
|
||||
from the modeline should've tipped people off that this was wrong.
|
||||
|
||||
Let's at least get rid of this engine struct in future, and have direct
|
||||
code dependencies between modules, so that at least this psychological
|
||||
barrier disappears.

Subject: [2/2] drm: sun4i: hdmi: Add support for sun4i HDMI encoder audio

|

Date: Fri, 10 Jan 2020 16:11:40 +0200
|
||||
|
||||
Add HDMI audio support for the sun4i-hdmi encoder, used on
|
||||
the older Allwinner chips - A10, A20, A31.
|
||||
|
||||
Most of the code is based on the BSP implementation. In it
|
||||
dditional formats are supported (S20_3LE and S24_LE), however
|
||||
there where some problems with them and only S16_LE is left.
