sgxAllocateDeviceMem: PVR2D_Ext_AllocExpMem failed

Lollipop

Other Parts Discussed in Thread: OMAP3530, 4430

Hi,

I'm using TI Graphics SDK 4_06_00_02. I could run some of the included demos. When I ran a browser, I got the following errors. What is this error? How do I resolve it? Thanks.

(EE) sgxAllocateDeviceMem: PVR2D_Ext_AllocExpMem failed

I'm running the X version provided in the SDK on omap3.

Hi,

You can check if fine tuning the PixmapPoolSizeMB Xorg driver parameter (by adding the below option in xorg.conf under Device section) helps here or not. For eg see below-

Option "PixmapPoolSizeMB" "200"

You need to restart the drivers after adding above option in xorg.conf device section (ie do a /etc/init.d/rc.pvr stop followed by /etc/init.d/rc.pvr start).

Thanks,

Prathap.

No. It still does not work. Where are these driver options documented, please? Thanks.

Can you please post the output log, with the debug version of the driver installed ? That should print out more information on where the memory allocation is failing. As you know, Pixmaps are used by a number of X apps, including X itself, for caching, composition so more information will help.

Please see attached file. Thank you.

This is a Xorg log. This is helpful, but what we really need is - the terminal log when debug drivers are installed.

Would you please give me more instructions on how to collect the log you need? The print out on the terminal did not contain any more information than in the Xorg log. Thanks.

Additional log. Thanks.

As the message indicates - there definitely seems to be a shortage of allocated buffers for your system. We have not tried with browsers as part of our validation - which browser is being used ?

Can you confirm the value of "XPROC_WORKAROUND_NUM_SHAREABLES" that is being set, by doing a printk of the value in the loop in the file services4\srvkm\common\buffer_manager.c, in BM_XProcWorkaroundFindNewBufferAndSetShareIndex function ?

Hi,

Can you try increasing XPROC_WORKAROUND_NUM_SHAREABLES in services4\srvkm\common\buffer_manager.c (line 1736).

By default it is 200, can you increase it to 4095. For OMAP4430, it has been configured to 4095 as below.

Thanks,

Hi,

In addition to above, you may also use the below patch for increasing SGX heap size if required -

Thanks,

Hi, Prathap.

I increased XPROC_WORKAROUND_NUM_SHAREABLES from 200 to 4095, and the memory problem disappeared. Thanks.
