Facing an issue with PVR.

Carol Suman Pinto

Hi,

I'm trying to use ducati codecs and SGX based video sinks on a non-debian based distribution. I followed the steps mentioned in the post.

http://e2e.ti.com/support/omap/f/849/p/249986/875729.aspx#875729

I'm facing issue with PVR modules.

Log when  X is started:

Can you please help me with what I'm missing?

Thanks in advance,

    Hi Carol.

    I too setup the graphics stack on a non-debian target.  It was a bit of a chore, especially getting the various packages to cross-compile properly.

    From the "could not get plugin ioctl base" error, it looks like drmCommandWriteRead() is failing.  I'd add debugging to that routine.  I don't recall if it is the default or not, but drmMsg() can send debugging to Xorg.0.log

    drmCommandWriteRead() is in libdrm.  Since you are in a non-debian environment, I'm guessing that you are compiling libdrm from source rather than using TI's binary package.  You need to be building libdrm (and a number of other packages) with the TI patches that are in the GLP release.  The stock libdrm will not work.

    Also, make sure your kernel is compiled with CONFIG_DRM and CONFIG_DRM_OMAP turned on.

    Regards,

        Steve

    Hi Steve,

    Thank you for your quick reply.

    Actually the module " omapdrm_pvr.ko "  wasn't  loaded. 

    I did "modprobe omapdrm_pvr.ko" and I was able to run pvrsrvinit and start X without any error.

    =========================================================================

    I have downloaded libdrm and other packages from the site https://launchpad.net/~tiomap-dev/+archive/release. I have included those packages in the buildroot  to make the compilation simpler.

    I'm still facing the "could not get plugin ioctl base" issue, but only when I'm trying to use the ducati plugins.

    libdce.c:460:   init    error: could not get plugin ioctl base: -22
    ERROR: Pipeline doesn't want to pause.

    Is libdrm the root cause ?

    Thanks in advance,

    Carol

    Hi Carol.

    I used the packages in the GLP release, but they are just a snapshot of the ones on launchpad.  If you are not cross-compiling you won't run into the issues that I did, such as Mesa wanting to use the same compiler for building both host tools and target libraries (ie, both x86 and ARM binaries).  Perhaps buildroot simplifies this compared to ptxdist which I used.

    "could not get plugin ioctl base" means that the routine I mentioned earlier -- drmCommandWriteRead() -- is failing.  And yes, that is in libdrm.  It would not surprise me to find out that it is something external to libdrm, such as a DRM kernel ioctl, that is failing, but libdrm is the start.

    Since it is libdce.c that is failing, have you got CONFIG_DRM_OMAP_DCE on in your kernel config?  Is the Ducati firmware loaded during boot?

    Regards,

        Steve

    Hi Steve,

    You are right, ducati firmware wasn't loaded. The link to ti-firmware-ipu-dce.xem3 created using  alternatives system ( used in the script 'ti-firmware-ipu-dce.postinst') was not right. Thanks a lot for pointing that out.

    I'm not facing the 'could not get plugin ioctl base' issue now.
