Problem loading pvrsrvkm.ko with Graphics SDK on 8148

Other Parts Discussed in Thread: TLC59108

I am trying to get Graphics SDK 's sgx driver work on my ubuntu ARM 12.04.

with linux-2.6.37-psp04.01.00.06.patch4.; ezsdk_dm814x-evm_5_03_01_15 ; graphics-sdk_4.04.00.02

the ubuntu arm 12.04 rootfs work fine without the ti81xxfb driver before this, I run a QT program with my lvds LCD.

Today ,I rebulid the kernel and the sgx driver, and run make install in graphics-sdk_4.04.00.02 dir to install the km and sdk to my rootfs

I use the 38xx-demo to install the sgx dirver module and sdk,and disable the origin x in the script , and reboot.

After reboot , the vpss ti81xxfb cmem syslink was loaded( vpssis load with vram=0:48m,1:1M,2:1M)

Then I try to run /etc/init.d/rc.pvr  ,it print out some error messages and hang there .

With lsmod ,the drm and pvrsrvkm module was loaded at this point.

What can I do to fix this problem?

below is the dmesg output:

    Hello,

    The EZSDK 5.03 is an old release you could move to the latest one 5.05.02. You could download it from here:

    software-dl.ti.com/.../index_FDS.html

    It contains :

    psp04.04.00.01

    graphics-sdk_4.04.00.02

    EZSDK 5.05.02 by default it will load these modules:

    bufferclass_ti          4950  0
    omaplfb                10794  0
    pvrsrvkm              155618  2 bufferclass_ti,omaplfb
    tlc59108                1545  0
    ti81xxhdmi             17685  0
    ti81xxfb               21979  2
    vpss                   74936  3 omaplfb,ti81xxhdmi,ti81xxfb
    syslink              1133911  0
    ipv6                  214095  14

    If you rebuild the pvrsrvkm.ko or some other module:

    1.The Linux kernel has to be built with "modules" support (make uImage modules)

    2.The kernel modules of the Graphics driver have to be built, after the linux kernel is built in the above manner. ie, the kernel modules need to match the kernel version that will actually run on the target.

    Best Regards,

    Margarita

    I go on fixing the problem today and found some other questions.
    As you list ,there's no drm.ko module loaded; drm module is build in to kernel by default.
    But the GRAPHICS SDK seem to build a drm.ko it self ,which have some symbol "drm_pvr_remove" ect
    pvrsrvdm.ko need this symbol.

    By the way, my board is a custom board, is tlc59108 is on the chip or just for evm board?

    Now I can get all the modules load correctly.  But, still the same error happen .(in ezsdk 5.03 and 5.05)

    I had try to load the pvr_drv.so to the xorg come with ubuntu arm 12, and found it's version is too old for the xorg.

    It seem pvr_drv.so and some other libarys is provided as bin form TI.

    A coording to the message provided by Robert C.Nelson,  it just can't work with ubuntu arm 12.

    It's that means I must give up using ubuntu or debian and try busy box without X, if I still warn 3d to work?
