Pandaboard ES ... SGX540 graphics driver options?

[jeffstory]

For some reason, my handmade xorg.conf had no effect. Something wrong in it perhaps.

I tried Xorg -configure to attempt to create a new one to edit, but no luck. man xorg.conf still refers to it so apparently it's not depreciated yet. Also, I use an xorg.conf in my AMD/nvidia desktop with Arch and it works, so I'm at a loss at the moment....

However, creating an /etc/X11/xorg.conf.d/10-monitor.conf did the trick of getting the "omap" driver to load. Still no luck getting omap to run.

$this->bbcode_second_pass_code('', 'Section "Monitor"

EndSection

Section "Screen"

Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1440x900"
EndSubSection
EndSection')


Possibly the problem is now related to the boot options in boot.scr are directing video output to the DVI (p1) in ArchARM, whereas Linaro and Ubuntu are setup to use HDMI (p2). What are your thoughts on this before I dig in to try redirect video to the HDMI(p2)

Actually, I would probably start by using the xorg.conf and cmdline settings that were on the ubuntu one.

More info and a quote from https://github.com/robclark/xf86-video-omap

$this->bbcode_second_pass_quote('', 'f')86-video-omap
Open-source X.org graphics driver for TI OMAP graphics

Currently relies on a closed-source submodule for EXA acceleration on
the following chipsets:
+ OMAP3430
+ OMAP3630
+ OMAP4430
+ OMAP4460
+ OMAP5430
+ OMAP5432


NOTE: this driver is work in progress.. you probably don't want to try
and use it yet. The API/ABI between driver and kernel, and driver and
acceleration submodules is not stable yet. This driver requires the
omapdrm kernel driver w/ GEM support.

EXA vs UXA? This is an open question..

This project: http://mer-project.blogspot.com/ sounds very interesting.

What is libhybris? Libhybris is a solution that allows non-Android systems such as glibc-based systems (like most non-Android systems are) to utilize shared objects (libraries) built for Android. In practice this means that you can leverage things like OpenGL ES 2.0 and other hardware interfacing provided within Android hardware adaptations.


On the PowerVR SGX, there was an API provided called WSEGL, for making plugins that were windowing systems (X11, Framebuffer, QWS, Wayland..) that allowed me to do just that.



If I understand this correctly, libhybris would be a viable solution for the lack of ARM GPU drivers for the Linux desktop. Just leverage the Android drivers!

This discovery gives me something to look forward to, running Arch + a proper GPU driver on my pandaboard !! This also gives me a reason to actually care about Wayland......
