g2d_clear and blit fails with GPU_alloc'd memory

What are the correct settings to use when installing galcore (insmod galcore) for the vivante 5.0.11 binaries. I currently have the GPU marginally running with the following settings. However I get a device fault from another device driver, which uses DMA, whenever I execute the g2d_clear command on the g2d_surface.

I load the module from with in the embedded application with the following settings for our i.MX6 solo:

" insmod /lib/modules/3.0.35/kernel/drivers/mxc/gpu-viv/galcore.ko" \
        " registerMemBase=0x00000000 registerMemSize=0x00004000 irqLine=-1" \
        " irqLine2D=42 registerMemBase2D=0x02200000 registerMemSize2D=0x00004000" \
        " irqLineVG=43 registerMemBase2D=0x02204000 registerMemSize2D=0x00004000" \
        " signal=48 baseAddress=0x80000000 fastClear=-1 " \
        " contiguousSize=0x006f50000 contiguousBase=0x9E000000 " );

If I use IPU allocated memory for the surfaces, the g2d_blit function works correctly, but slowly. It does not work when I allocate memory from the g2d driver.

Thank you

Hi Mark

On Uboot, try gpumem = 128M. However you should try upgrade your bsp.
