multiple instance of texture streams

O'Mellin

Team,

To create double instance of texture streaming (Open GL ES) double instance I had to modify two drivers in the omap -SDK 4.05.00-03:

1 - 'bufferclass_ti.ko' by increasing the # define DEVICE_COUNT January to February in 'GFX_Linux_KM \ services4 \ 3rdparty \ bufferclass_ti \ bc_cat.c'

2 - 'pvrsrvkm.ko' by increasing the # define SYS_DEVICE_COUNT March to April in 'GFX_Linux_KM \ services4 \ system \ omap3630 \ sysinfo.h'

For now I have found no side effects, everything seems to work well with texture two streams simultaneously.

But it would be reassuring to know the reasons for this voluntary limitation of the SDK.

Some feedback from the GFX SDK Team:
"The multiple device path is untested. What the customer has done is right, based on previous work.
An alternative that we have tested is - to use a single bc device, but use multiple buffers as separate channels and update the buffers. Both are equivalent."
