2014-09-10drm: move drm-lock API to drm_legacy.hDavid Herrmann1-3/+3
Same as the other legacy APIs, most of this is internal, so prefix it with drm_legacy_* and move into drm_legacy.h. Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2014-06-10drm: Remove DRM_ARRAY_SIZE() for ARRAY_SIZE()Damien Lespiau1-1/+1
I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used in a few places. I suspect its usage has been spread by copy & paste rather than anything else. Let's just remove it for plain ARRAY_SIZE().

2013-12-18drm: Kill DRM_HZDaniel Vetter1-1/+1
We don't have any userspace interfaces that use HZ as a time unit, so having our own DRM define is useless. Remove this remnant from the shared drm core days. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>

2013-08-07drm/mm: add "best_match" flag to drm_mm_insert_node()David Herrmann1-2/+4
Add a "best_match" flag similar to the drm_mm_search_*() helpers so we can convert TTM to use them in follow up patches. We can also inline the non-generic helpers and move them into the header to allow compile-time optimizations. To make calls to drm_mm_{search,insert}_node() more readable, this converts the boolean argument to a flagset. There are pending patches that add additional flags for top-down allocators and more. v2: - use flag parameter instead of boolean "best_match" - convert *_search_free() helpers to also use flags argument Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>

2012-07-20drm/sis: fixup sis_mm ioctl structsDaniel Vetter1-3/+3
Userspace uses long in quite a few places more than the kernel. Which gives me neat proof that I'm the only guy on this side of the galaxy who ever tried to run glxgears on a 64bit machine with sis graphics on linux. Note that the longs in drm_sis_mem_t aren't aligned properly, so this won't even work with 32bit userspace on 64bit kernel as-is. Hence the patch can't break that, either. Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...

2011-12-22drm/sman: rip out owner trackingDaniel Vetter1-1/+1
In contrast to kms drivers, sis/via _always_ associated a buffer with a drm fd. So by the time we reach lastclose, all open drm fds are gone and with them their associated objects. So when sis/via call drm_sman_cleanup in their lastclose funcs, that will free 0 objects. The owner tracking now serves no purpose at all, hence rip it ou. We can't kill the corresponding fields in struct drm_memblock_item yet because we hijack these in the new driver private owner tracking. But now that drm_sman.c doesn't touch ->owner_list anymore, we need to kill the list_move hack and properly add the item to the file_priv list. Also leave the list_del(&obj->owner_list) in drm_sman_free for the moment, it will move to the drivers when sman disappears completely. v2: Remove the redundant INIT_LIST_HEAD as noted by Chris Wilson Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2011-12-22drm/sis: track obj->drm_fd relations in the driverDaniel Vetter1-8/+14
By attach a driver private struct to each open drm fd. Because we steal the owner_list from drm_sman until things settle, use list_move instead of list_add. This requires to export a drm_sman function temporarily before drm_sman will die for real completely. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2010-08-17drm: block userspace under allocating buffer and having drivers overwrite it ↵Dave Airlie1-6/+6
(v2) With the current screwed but its ABI, ioctls for the drm, Linus pointed out that we could allow userspace to specify the allocation size, but we pass it to the driver which then uses it blindly to store a struct. Now if userspace specifies the allocation size as smaller than the driver needs, the driver can possibly overwrite memory. This patch restructures the driver ioctls so we store the structure size we are expecting, and make sure we allocate at least that size. The copy from/to userspace are still restricted to the size the user specifies, this allows ioctl structs to grow on both sides of the equation. Up until now we didn't really use the DRM_IOCTL defines in the kernel, so this cleans them up and adds them for nouveau. v2: fix nouveau pushbuf arg (thanks to Ben for pointing it out) Reported-by: Linus Torvalds <torvalds@linuxfoundation.org> Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-10-18SiS DRM: fix the memory allocator if the SIS FB is built as a moduleDavid Howells1-4/+4
Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM code initialises the mm allocation hooks, but _only_ if the SIS FB is not built as a module because it depends on CONFIG_FB_SIS, and that's unset if the SIS FB is not built in. It must check CONFIG_FB_SIS_MODULE as well.

2008-07-14drm: reorganise drm tree to be more future proof.Dave Airlie1-0/+333
With the coming of kernel based modesetting and the memory manager stuff, the everything in one directory approach was getting very ugly and starting to be unmanageable. This restructures the drm along the lines of other kernel components. It creates a drivers/gpu/drm directory and moves the hw drivers into subdirectores. It moves the includes into an include/drm, and sets up the unifdef for the userspace headers we should be exporting. Signed-off-by: Dave Airlie <airlied@redhat.com>
