-TODO
|
|
|
-. add video decode/encode support (via syslink3 + codec-engine)
|
|
|
- . NOTE: with dmabuf this probably could be split into different driver
|
|
|
- so perhaps this TODO doesn't belong here
|
|
|
-. where should we do eviction (detatch_pages())? We aren't necessarily
|
|
|
- accessing the pages via a GART, so maybe we need some other threshold
|
|
|
- to put a cap on the # of pages that can be pin'd. (It is mostly only
|
|
|
- of interest in case you have a swap partition/file.. which a lot of
|
|
|
- these devices do not.. but it doesn't hurt for the driver to do the
|
|
|
- right thing anyways.)
|
|
|
- . Use mm_shrinker to trigger unpinning pages. Need to figure out how
|
|
|
- to handle next issue first (I think?)
|
|
|
- . Note TTM already has some mm_shrinker stuff.. maybe an argument to
|
|
|
- move to TTM? Or maybe something that could be factored out in common?
|
|
|
-. GEM/shmem backed pages can have existing mappings (kernel linear map,
|
|
|
- etc..), which isn't really ideal.
|
|
|
-. Revisit GEM sync object infrastructure.. TTM has some framework for this
|
|
|
- already. Possibly this could be refactored out and made more common?
|
|
|
- There should be some way to do this with less wheel-reinvention.
|
|
|
-. Solve PM sequencing on resume. DMM/TILER must be reloaded before any
|
|
|
- access is made from any component in the system. Which means on suspend
|
|
|
- CRTC's should be disabled, and on resume the LUT should be reprogrammed
|
|
|
- before CRTC's are re-enabled, to prevent DSS from trying to DMA from a
|
|
|
- buffer mapped in DMM/TILER before LUT is reloaded.
