The drm subsystem also uses the video= kernel parameter, and in the
documentation refers to the fbdev documentation for that parameter.
However, that documentation also says that instead of giving the mode using
its resolution we can also give a name. However, DRM doesn't han
In some cases, in order to accomodate with displays with poor EDIDs, we
need to ignore that the monitor alledgedly supports audio output and
disable the audio output.

Rewrite the command line parser in order to get away from the state machine
parsing the video mode lines.
Hopefully, this will allow to extend it more easily to support named modes
and / or properties set directly on the command line.

Hi,
The proprietary stack for the RaspberryPi allows for a number of video
parameters widely used by their users, but yet don't have any equivalents
in the mainline kernel.
Those options are detailed here:

While not all
The current code assumes as soon as the device is an HDMI one that it
supports an audio sink. However, strictly speaking, this is exposed as a
separate part of EDID.
This can be checked through the drm_detect_monitor_audio function, so let's
use it and make sure that we can use the HDMI monitor as

Hello,
This series is a first attempt to fix the slow down in performance introduced by
"[PATCH v2] drm: Block fb changes for async plane updates" where async update
falls back to a sync update, causing igt failures of type:

In the case of async update, modifications are done in place, i.e. in the
current plane state, so the new_state is prepared and the new_state is

normal sync update).
To cleanup the old_fb properly, it needs to be placed in the ne

Not a bug at all. I'd call it "usability problem")
User can't enable TTM (which is required for virtualbox) unless she enables
some redundant driver.

These patches add panel driver for ili9341-based panels in parallel RGB mode.
The driver was developed for DispleyTech DT024CTFT LCD panel [1] which features
ILI9341 chip [2].
The driver was tested on the Allwinner A13 (sun5i) platform.
The driver supports 240x320 pixel resolution with 18-bit RGB
