True, I renamed that file, since I got the message that it couldn't find
module omap. First I renamed it to omap_drv.so, which gave me the same
error, then I tried pvr_drm.so which is the attatched logfile. Both of
them are the omap_pvr_drv.so file.
Should there be a omap_drv.so file in the same directory as the
omap_pvr_drv.so file? In that case there isn't, the omap_pvr_drv.so file
is the only one in that directory when extracting that tarball. Actually
there is no file at all named omap_drv.so:
$ find . -name "omap_drv.so"
return nothing, while just omap gives
$ find . -name "omap*"
./usr/lib/debug/usr/lib/xorg/modules/drivers/omap_pvr_drv.so
./usr/lib/xorg/modules/drivers/omap_pvr_drv.so
which is the same as "*drv*" gives.

There is an omap_drv.so which should be the xorg driver to load.. it
will attempt to load (if present) omap_pvr_drv.so as a submodule for
EXA accel. I'm not entirely sure why it is named pvr_drv.so in your
filesystem, but from list of symbols it seems to match what I would
expect to be omap_pvr_drv.so

Hi.
I am not 100% sure this is the correct place to ask, but since I know at
least Ricardo Salveti are working on these drivers for omap4, and I
haven't heard anything from the ppa's mailing list, I try to ask here.
If this was completely wrong I'm sorry, but would still appreciate a
hint as to where to ask and who to contact.
We are compiling what is now HEAD in the tilt-3.3 branch from the TI
landing team. To compile the module needed for the powervr drivers, we
had to get the pvr-omap4-dkms-1.7.15 and pvr-omap4-1.7.15 from
http://ppa.launchpad.net/tiomap-dev/omap-trunk/ubuntu/pool/main/p/
We downloaded the tar.gz from those, extracted them and compiled them.
Problem starts when we boot the board and try to run startx. The xorg
config which comes with the later package is loaded, but when trying to
start X I get the error:
(EE) Failed to load /usr/lib/xorg/modules/drivers/pvr_drv.so:
/usr/lib/xorg/modules/drivers/pvr_drv.so: undefined symbol: OMAPFinishAccess
None of the libraries in pvr-omap4 contains this symbol, so I'm
wondering if I'm doing something wrong, or if there is something wrong
with the binary?
When comparing to the library from rsalveti, from
people/rsalveti/pvr-omap4.git, I see that the dynsym table contains 232
entries, but there are only 64 entries in the same table in the other
library. Is this correct, or should there be more entries in the 1.7.15
library?
Both the Xorg log and the readelf output from both libraries are
attached, if you have questions/need more info, please do not hesitate
to ask.
Thank you in advance for the help, and thank you for the great work you
put in for making embedded Linux better.
Best regards
Martin Ertsaas
