[PATCH 0/3] Adding xf86-video-omap support for Pandaboard

[Nicolas Dechesne]

From: Nicolas Dechesne <n-dechesne@ti.com>

Hi there,

here is a refreshed series to add support for xf86-video-omap for
Pandaboard.

We've switched all our OMAP4 and OMAP5 support on this new X11 video
driver, which is hosted here:
http://cgit.freedesktop.org/xorg/driver/xf86-video-omap/

that drivers requires changes in libdrm which have all been merged
into upstream, we just need to enable the 'omap' support in libdrm
which is still experimental.

we try to restrict this to 'omap4|omap5' machines so that we don't
impact other TI devices.

this series is tested on PandaES, with:

BB_VERSION        = "1.16.0"
TARGET_ARCH       = "arm"
TARGET_OS         = "linux-gnueabi"
MACHINE           = "pandaboard"
DISTRO            = "poky"
DISTRO_VERSION    = "1.3+snapshot-20121018"
TUNE_FEATURES     = "armv7a vfp neon cortexa9"
TARGET_FPU        = "vfp-neon"
meta
meta-yocto        = "master:e6e2b9bd66100c078c029ca7e34829cf1dfb5490"
meta-ti           = "master:9d5f7904444febfaeaacce88f50c5ceb700552f1"

The pandaboard task list is:
DONE: refresh OMAP4 kernel
DONE: introduce new X11 video driver
TODO: introduce customized Gst/gst-ducati and libdce
TODO: add support for DRI2, SGX accelerated EXA, DRI2Video

Some of these patches could certainly make their way in oe-core at
some point.

This Xf86-video-omap driver has been tested with 1.11 Xserver, but
also locally with 1.12. With 1.12 xrandr rotation is working, as a few
rotation related bugs were fixed indeed in 1.12, that could be
backported in 1.11 if needed. xrandr mode setting has been tested with
1.11 and 1.12. Multi display support should work too.

[PATCH 2/3] xf86-video-omap: add new recipe for OMAP4/5 X11 video driver

[Nicolas Dechesne]

From: Nicolas Dechesne <n-dechesne@ti.com>

Since this component is still actively being developed, let's use
a _git.bb recipe. We can introduce 'x.y' version later.

Even though xf-video-omap can be combined with private/restricted
EXA sub-driver for SGX/PVR, it can also work without it. In which
case EXA aren't using SGX, but all standard driver features still
work, and it is a replacement for xf-video-fbdev.

[PATCH 3/3] pandaboard: use xf86-video-omap by default in XSERVER config

[Nicolas Dechesne]

From: Nicolas Dechesne <n-dechesne@ti.com>

Also we need to pull in module-exa as xf86-video-omap relies
on it, at run time.

And replaced the default xorg.conf for 'omap4' machine to take
new driver into account. Do not enable HWcursor (e.g. mouse
using DSS overlay) to keep things simple for now..
