Hi SI,
It is fixed 128MB for TILER 1D pages. What is the usecase requiring this to modify?
Are you seeing issue with the buffer allocations are not fitting within 128MB?

Hi SI,
Please refer PSDKLA-3753 in Post release update
processors.wiki.ti.com/.../Processor_SDK_Linux_Automotive_Post_Release_Fixes

This has fix for allocating Graphics buffers and omap-bo buffers in non-Tiler region.
Please make sure for ipumm, this can not be used, buffers need to be in TIler.
By default all GPU allocations will happen in CMA region.

Thanks
Ramprasad
