Hello!
I recently installed TI's Linux Graphics SDK on my Beaglebone and while I seem to be able to successfully run the demos which come with the SDK (for example, when I run OGLESSkybox I see the hot air balloon flying over the ocean on the LCD) I am worried about some errors and warnings which are being output when I run them (the SDK was built in debug mode so a lot is being put out on the console by the running demo):
PVR:(Error): PVRSRVMetricsTimeNow: using (potentially) low resolution timer [95, /pvr_metrics.c]
....
PVRShell: EGL 1.4 initialized
PVR:(Error): OSIsProcessPrivileged: not implemented, default returns false [574, /osfunc_um.c]
PVR:(Error): PrepareTextureUpload: Can't do sub tile twiddling to unaligned surface/stride! [1606, /sgxtransfer_queue.c]
PVR:(Warning): SGXQueueTransfer: all paths failed in TQ, returning error (this is not a bug) [9605, /sgxtransfer_queue.c]
PVR:(Warning): HWTQTextureUpload: Failed to load texture image (error=19). Falling back to SW [533, /texdata.c]
PVR:(Error): SGXQueueTransfer: all paths failed [9609, /sgxtransfer_queue.c]
PVR:(Warning): HWTQTextureUpload: Failed to load texture image (error=3). Falling back to SW [533, /texdata.c]
The whole debug output when running the OGLESSkybox demo is in the attached archive in SkyBox-demo_Output.txt. Output of the 335x-demo script is in 335x-demo_script_output.txt and the output of the gfc_check script is in gfx_check_script_output.txt.
Additional information: rc.pvr script with the "start" parameter is being called after power up to load the drivers.
Can anyone shed some light on what the errors and warnings mean? Are they critical? I am especially worried about the last warning which reports that some functionality is falling back to SW. This makes me think the hardware is not being utilized to its fullest extent and may cause execution delays.
Thanks for your help.
