Talk:Drivers justification

List hardware here which is underutilised/undocumented


PowerVR

 3d rendering (hopefully onto 5mbit on omap2420 SARAM buffer

IVA

 Conversion from RGB to YUV, decoding video frames, scaling and blitting bitmaps

5mbit SRAM

 Possible use as an RGB framebuffer for powervr/flat x11 surface.
 Would require the IVA to convert and push this RGB data onto SDRAM "standard" surface for the Epson LCD to display on screen quickly.


<jott> lcuk: have you actually tried to investigate accessing the sram? <lcuk> where is it... ? <lcuk> this is what documentation is all about <jott> lcuk: drivers/video/omap/dispc.c atleast reads "#define OMAP2_SRAM_START 0x40200000"
