| 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. |
