AM335X omapdrm_pvr.ko

Igor Bondarchuk

Hi,

Previously I'm sorry for my English.

I have some trouble.

I'm use ti-processor-sdk-linux-am335x-evm-02.00.00.00 at BB white.

In prebuild filesystem tisdk-rootfs-image-am335x-evm I found sgx driver based on omapdrm_pvr.ko and run via pvrsrvinit. It work fine.

Your prebuild modules omapdrm_pvr.ko size is 239.7kB.

pvrsrvinit is located in /usr/bin.

In board-support/extra-drivers/omapdrm-pvr-1.9.2253347 placed sourses only omapdrm-pvr.ko. No found source of pvrsrvinit.

After build omapdrm-pvr-1.9.2253347, omapdrm_pvr.ko have size 3.9MB.

Module build with the ti-linux-kernel/ti-linux-4.1.y Linux kernel from SDK.

After install module to arago-base-tisdk-image-am335x-evm they won't work.

-----------------------------------------------------------------------------------------------------------

If use Graphics-SDK-05.01.01.02. and istall modules follow instructions install 8.x SGX release user libraries and kernel modules, I see error

/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=4).

#modprobe omaplfb
[ 1716.280620] omaplfb: Unknown symbol register_vsync_cb (err 0)
[ 1716.287136] omaplfb: Unknown symbol unregister_vsync_cb (err 0)

I try follow this way, "https://github.com/RobertCNelson/bb-kernel/commit/181731e134d23a0fd8275db32fc085f7502d0437"

--------------------------------------------------------------------------------------------------------------------

How fix this:

/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=4)
omaplfb: Unknown symbol register_vsync_cb (err 0)
omaplfb: Unknown symbol unregister_vsync_cb (err 0)

Why kernel from processor-sdk won't work with Graphic SDK 5?

Where to find pvrsrvinit and libraries to it if you use the "omapdrm" module

Where can I find the instructions to launch the graphic component for the latest ti-processor-sdk-linux-am335x-evm-02.00.00.00

Hello Igor,

You've gotten the same errors as in this thread e2e.ti.com/.../483575, please check it.

Best regards,
Kemal

Thanks for the quick response.

depmod -a not fix problem with Graphics_SDK_5_01_01_02.

still have:
/usr/local/bin/pvrsrvctl: SrvInit failed (already initialized?) (err=4).
#modprobe omaplfb
omaplfb: Unknown symbol register_vsync_cb (err 0)
omaplfb: Unknown symbol unregister_vsync_cb (err 0)

With omapdrm_pvr.ko still have problem:
pvrsrvinit and lib's not found in SDK.

processors.wiki.ti.com/.../Processor_Linux_SDK_Graphics_and_Display

Say's that lib's are part of SDK. but it is not clear where to find them.

In the second reference question was not able to run the demo application. You could say the question is not answered.

Help me please.

Best Regards,
Igor

Seems the pvrsrvctl was already initialized and the register_vsync_cb, unregister_vsync_cb has not exported by tilcdc_crtc. Could you create one txt file and paste the output of these commands ps, lsmod, lsof and attach the log?
