Compiler/TDA2PXEVM: dce Engine_open failed after using vdrm

Hi Ramprasad,

   Thansk for your help. I add the two patches, and enable omap_drm in the kernel, but the error still existed. I pasted the change and kernel log below:

Hi yang,

Which application you are trying to use now to invoke Engine_open?

You don't need add this application is /etc/powervr.ini. 

From the dmesg logs, omapdrm is probed now. 

Can you check if you can see this sysfs

cat /sys/kernel/debug/dri/1/tiler_map 

Hi Ramprasad,

         Now the android media process invoke the Engine_open.  I did nothing about /etc/powervr.ini.

 and I can not see the sysfs:

jacinto6evm:/ # cat /sys/kernel/debug/dri/1/tiler_map
cat: /sys/kernel/debug/dri/1/tiler_map: No such file or directory

Hi yang,

ENgine_open is not able to get handle here.

Can you share this trace?

cat /sys/kernel/debug/remoteproc/remoteproc1/trace0

Want to check if remoteproc is loaded without any issue.

Also check this in dmesg

dmesg | grep remoteproc

RamPrasad

Hi Ramprasad,

the log is listed below:

Hi Ramprasad,

We use Android 8.1 & 6AO1.1. 

And for this error,  I found in dce   the origin code use /dev/dri/renderD128,  but this is vdrm device, so I change it to /dev/dri/renderD131 which is omapdrm device, and this error can be fixed.  But there is other issue, list below.  when I check the the whole code, I found /dev/dri/renderD128 many times, and no /dev/dri/renderD131.  Should I change all /dev/dri/renderD128 to /dev/dri/renderD131?
