 Posted: Wed Mar 27, 2013 4:34 pm Post subject: HowTo(?) build powervr sgx drivers ( igepv2, Beagle XM) |
 |
|
I've been attempting to install the above mentioned accelerated graphics drivers on gentoo using the directions on the TI website. Their prerequisites include using NFS for building which I didn't use. Before I ask specific questions, I'm wondering if someone has done this successfully with a gentoo setup ( most are using Ubuntu or yocto), and can perhaps provide some tips or tricks.
I'll post later what I've accomplished so far (I believe I'm most of the way there).[/url]

I'm going to try again and post detail here what I'm doing.
The drivers are coming from here:
http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html
I'm following the install guide from here:
http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide
Instead of setting up an NFS server, I'm mounting the filesystem of my SD on my PC (desktop):
| Code: |
mount /dev/sdi2 /mnt/igep-root/
|
| Code: | | host $ export ARCH=arm |
I edited the Rules.make file like so:
| Code: |

I execute the following:
| Code: | | make BUILD=release OMAPES=5.x SUPPORT_XORG=1 install |
According to the instructions, the above command should:
| Quote: | | ...install only the graphics kernel modules(pvrsrvkm.ko, drm.ko) to target file system as mentioned in Rules.make |
Things seem to run without error:
| Code: |
exporting necessary variables and installing...
########################################################
Please ensure that PSP Linux kernel is re-built atleast once,
Please refer online guide for further details.
########################################################
creating directories...
copying startup files...
copying user space graphics libraries to target file system...
copying install information to target file system...
|
The above happened pretty quickly, and I got suspicious that it wasn't actually doing what it was supposed to. Instead I tried:
| Code: | | make BUILD=release OMAPES=5.x SUPPORT_XORG=1 |
THEN
| Code: | | make BUILD=release OMAPES=5.x SUPPORT_XORG=1 install |
This resulted in the modules being built, then installed (hopefully) correctly.
The next step as I understand it is to run:
| Code: | | /etc/init.d/omap-demo |
Here's the log:
http://bpaste.net/show/87318/
So, I unmount the SD card, plug it into the igepv2 and run it. What results is what looks to be an install of the modules.
When I try to load the pvr module, dmesg shows errors related to unknown symbols:
| Code: |
[ 160.425109] pvrsrvkm: Unknown symbol drm_pvr_dev_remove (err 0)
[ 160.427337] pvrsrvkm: Unknown symbol drm_pvr_dev_add (err 0)
|
Here's the whole dmesg output:
http://bpaste.net/show/87316/
It appears the install, at least, was successful. Googling the above error returns the following link:
http://forum.isee.biz/viewtopic.php?f=83&t=7225
It appears the above problem was due to the modules and kernel with a mismatched date-stamp(?). All I know is that when I built kernel and modules (including SGX) without powering off the device, the modules seem to load successfully. I've got some other python problems to solve, but I believe I am close to running XBMC which is my goal.
