Hi,
My company is working on a AM3517 board. We are using Technexion's
TAM3517 board for development right now.
I was working on TI's SDK a few weeks ago but some more urgent things
came up. I would definitely like to help if we can get it working in
Buildroot. I can also help in testing.
I don't know much about the history about TI's GFX SDK. I don't know
about the soft float issue either. I was trying to run it with mfpu=neon
parameter in the toolchain.
There are some other things I'm not certain.
I was working with 4_09_00_01 version and I think it works on AM35xx right?
Also I thought TI only supported kernels up to 2.6.37 for AM3517. I
can't remember where I get that idea, but I know Technexion doesn't
provide any later kernels for their AM3517 boards.
I don't know how buildroot works exactly but I started reading the
documentation. I hope I can help. We are hoping to use EGL and Qt5, it
will be easier to configure them and put the necessary files into the
rootfs if Buildroot handles everything.
Sorry if I wrote technically incorrect stuff, I begin working on

This is WIP of adding the TI Graphics SDK to Buildroot
Current Status:
Kernel Drivers load without errror.
pvrsrvctl starts with no errors.
Some demos run, others do not.
gstreamer videotestsrc ! eglglessink does not work.
TODO:
Install startup files for sgx core.
Create .pc files to simplify additional packaging.
Hard Float Binaries
Testing, lots of testing.
Additional Info:
I've been using the 3.9.6-x3 tag of the kernel at
https://github.com/RobertCNelson/stable-kernel by use of the
LINUX_OVERRIDE_SRCDIR option.
You must use a soft-float toolchain (ie Code Sourcery) as the binaries
provided by the Graphics SDK are soft-float. (hard float is on the TODO
list)
To load the driver manually use the following:
modprobe omaplfb
modprobe bufferclass-ti
pvrsrvctl --start --no-module

It's not really _the_ graphics SDK, since it only supports a subset of
TI platforms (no OMAP1, OMAP2 or Davinci, and I'm not sure about OMAP5
either).

We don't usually create pc files if the package doesn't provide them.
It's not really needed, because packages that use the library will anyway
not use pkg-config to get the package info.

Doesn't the package contain soft-float binary libraries? Then
hard-float won't be possible, right?

Please keep a changelog of the history of your patch in the commit
message, so we can keep track of which review comments you've already
taken into account.
In this particular case, I notice that Thomas repeats a lot of review
comments that I've made a week ago, so writing "review comments from
Arnout not taken into account" would have helped :-) Or maybe you missed
those?
Regards,
Arnout

well, historically, in the Pandaboard days (OMAP4/OMAP5), a different
graphics SDK was being used. While it was based on the same delivery
from the GPU vendor (IMG), the entire GFX stack was heavily
improved/modified to work with the omapdrm driver and dmabuf. I don't
think what you call 'the TI graphics SDK' was ever used on Pandaboard.
That said, i am no longer involved with that, and things might have
changed or might change, so you need to understand from TI what is
their commitment (if any) to support OMAP4 in this GFX SDK moving
forward, especially given that the PandaBoard community seems to be
(slowly but surely) disappearing... I expect things might get better
for OMAP5, but the problem here might be the lack of board to test ;-)

The SDK did support OMAP4 in 4_04_00_02. OMAP1/2 devices are too outdated to consider in the package.
Focus of this package is on the frame buffer based devices. Omapdrm/dmabuf and additional changes will be merged eventually.

well, historically, in the Pandaboard days (OMAP4/OMAP5), a different graphics SDK was being used. While it was based on the same delivery from the GPU vendor (IMG), the entire GFX stack was heavily improved/modified to work with the omapdrm driver and dmabuf. I don't think what you call 'the TI graphics SDK' was ever used on Pandaboard.
That said, i am no longer involved with that, and things might have changed or might change, so you need to understand from TI what is their commitment (if any) to support OMAP4 in this GFX SDK moving forward, especially given that the PandaBoard community seems to be (slowly but surely) disappearing... I expect things might get better for OMAP5, but the problem here might be the lack of board to test ;-) _______________________________________________

Hi,
My company is working on a AM3517 board. We are using Technexion's
TAM3517 board for development right now.
I was working on TI's SDK a few weeks ago but some more urgent things
came up. I would definitely like to help if we can get it working in
Buildroot. I can also help in testing.
I don't know much about the history about TI's GFX SDK. I don't know
about the soft float issue either. I was trying to run it with mfpu=neon
parameter in the toolchain.
There are some other things I'm not certain.
I was working with 4_09_00_01 version and I think it works on AM35xx right?
Also I thought TI only supported kernels up to 2.6.37 for AM3517. I
can't remember where I get that idea, but I know Technexion doesn't
provide any later kernels for their AM3517 boards.
I don't know how buildroot works exactly but I started reading the
documentation. I hope I can help. We are hoping to use EGL and Qt5.
Sorry if I wrote technically incorrect stuff, I worked on SGX SDK for a
short while last month and I realize I have forgotten most of what I did
now : )
