drm/gem: Don't call drm_mmap from drm_gem_mmap

2014-09-24T01:42:58+00:00

The only user I could dig out was i915 back when ums+gem was still a thing. But we've just very much killed that, and even when someone screams about that we should resurrect that with a special hack (wrapping drm_gem_mmap) in i915, not in the core code. So good riddance to another entry point of the legacy buffer mapping code. Signed-off-by: Daniel Vetter Reviewed-by: David Herrmann Acked-by: Alex Deucher Signed-off-by: Dave Airlie

drm/gem: Fix kerneldoc typo

The drm_gem_private_object_init function is called drm_gem_object_init in its kerneldoc. Fix it. Signed-off-by: Laurent Pinchart Signed-off-by: Daniel Vetter

drm: Move piles of functions from drmP.h to drm_internal.h

2014-09-12T09:16:29+00:00

This way drivers can't grow crazy ideas any more, and it also helps a bit in reviewing EXPORT_SYMBOLS. v2: Even more stuff. Unfortunately we can't move drm_vm_open_locked because exynos does some horrible stuff with it. Signed-off-by: Daniel Vetter

drm/gem: remove misleading gfp parameter to get_pages()

2014-07-07T22:29:53+00:00

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.

drm/gem: replace misleading comment

Here's my drm documentation update and driver api polish pull request. Alex reviewed the entire pile, I've applied a little bit of spelling polish in a few places since then and otherwise the Usual Suspects (David, Rob, ...) don't seem up to have another look at it (I've poked them on irc). So I think it's as good as it gets ;-) Note that I've dropped the final imx breaker patch since that's blocked on imx getting sane.

There is no need to initialize this variable, so drop it. Otherwise, the compiler won't warn if we use it unintialized. Reviewed-by: Daniel Vetter Signed-off-by: David Herrmann
