2014-07-08drm/gem: remove misleading gfp parameter to get_pages()David Herrmann6-17/+28
drm_gem_get_pages() currently allows passing a 'gfp' parameter that is passed to shmem combined with mapping_gfp_mask(). Given that the default mapping_gfp_mask() is GFP_HIGHUSER, it is _very_ unlikely that anyone will ever make use of that parameter. In fact, all drivers currently pass redundant flags or 0. This patch removes the 'gfp' parameter. The only reason to keep it is to remove flags like __GFP_WAIT. But in its current form, it can only be used to add flags. So to remove __GFP_WAIT, you'd have to drop it from the mapping_gfp_mask, which again is stupid as this mask is used by shmem-core for other allocations, too. If any driver ever requires that parameter, we can introduce a new helper that takes the raw 'gfp' parameter. The caller'd be responsible to combine it with mapping_gfp_mask() in a suitable way. The current drm_gem_get_pages() helper would then simply use mapping_gfp_mask() and call the new helper. This is what shmem_read_mapping_pages{_gfp,} does right now. Moreover, the gfp-zone flag-usage is not obvious: If you pass a modified zone, shmem core will WARN() or even BUG(). In other words, the following must be true for 'gfp' passed to shmem_read_mapping_pages_gfp(): gfp_zone(mapping_gfp_mask(mapping)) == gfp_zone(gfp) Add a comment to drm_gem_read_pages() explaining that constraint.

2014-07-08drm/omap: use __GFP_DMA32 for shmem-backed gemDavid Herrmann1-9/+8
OMAP requires bo-pages to be in the DMA32 zone. Explicitly request this by setting __GFP_DMA32 as mapping-gfp-mask during shmem initialization. This drops HIGHMEM from the gfp-mask and uses DMA32 instead. shmem-core takes care to relocate pages during swap-in in case they have been loaded into the wrong zone. It is _not_ possible to pass __GFP_DMA32 to shmem_read_mapping_page_gfp() as the page might have already been swapped-in at that time. The zone-mask must be set during initialization and be kept constant for now. Remove the now superfluous TODO in omap_gem.c.

2014-06-18drm/i915: use shmem helpers if possibleDavid Herrmann1-7/+1
Instead of shuffling gfp-masks all the time, use the shmem_read_mapping_page() helper. Note that __GFP_IO and __GFP_WAIT are set in mapping_gfp_mask() for i915, so the behavior is still the same.

This was a half-finished hack before, just enough to handle the shared aux/i2c pad thing on G94 and up. We got lucky with locking etc up until now, as this was (generally) all protected by the DRM mode_config lock. It's about to become a lot more likely to hit the races.
