Building SGX 4.08.00.02 with X11 suport for kernel 3.7

Fernando Rocha

Hello everyone,

I'm using https://github.com/RobertCNelson/stable-kernel, branch v3.7.x to try to build sgx modules for a beagleboard-xm rev C.
I made the changes indicated by http://processors.wiki.ti.com/index.php/SGXDbg#Unable_to_build_graphics_SDK_with_SUPPORT_XORG.3D1_for_3.3_.26_above_kernels,
and the modules build ok, with only one warning:

WARNING: "pci_bus_read_config_dword" [/home/fernando/kernel-3.7/stable-kernel/ignore/ti-sdk-pvr/Graphics_SDK/GFX_Linux_KM/services4/3rdparty/linux_drm/drm.ko] undefined!

And when i try to init the sgx system, i get this when it tries to insert the drm.ko module:

[ 2549.671997] drm: Unknown symbol pci_bus_read_config_dword (err 0)

I tried to remove some defines regarding PCI on drm.ko makefile, but it brought a lot of errors.

Is there someone that successfully built and used the SGX with x11 support on newer kernels?

Thank you very much.

Best regards,

Fernando

Hi Fernando,

What happens if you the Master branch?

Could you give more details about your settings?

Hi,
Please define a dummy function in GFX_Linux_KM/services4/3rdparty/linux_drm/pvr_drm_stubs.c of the graphics SDK release package & build.

I will update the sgxdbg page with this info.

Also please note that 04.09.00.01 is the latest graphics SDK release.

Thanks,
Prathap.

Hi Prathap and Tsvetolin,

I tried your proposed solution to build sgx 4.08.00.02 with kernel 3.7 and it build ok, without the warning i was getting before.

Also, i tried to build the 4.09.00.01 with kernel 3.9, and got a simmillar warning, complaining about pcie_capability_read_dword not being defined.

I did the same as Prathap told and it built with no problem.

I couldn't try it yet, but as soon as i manage to do it, i get back to you.

Thank you very much for your help.
