| TODO |
| . check error handling/cleanup paths |
| . add drm_plane / overlay support |
| . add video decode/encode support (via syslink3 + codec-engine) |
| . still some rough edges with flipping.. event back to userspace should |
| really come after VSYNC interrupt |
| . 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. |
| . Review DSS vs KMS mismatches. The omap_dss_device is sort of part encoder, |
| part connector. Which results in a bit of duct tape to fwd calls from |
| encoder to connector. Possibly this could be done a bit better. |
| . Add debugfs information for DMM/TILER |
