2009-12-18drm: convert drm_ioctl to unlocked_ioctlArnd Bergmann
drm_ioctl is called with the Big Kernel Lock held, which shows up very high in statistics on vfs_ioctl. Moving the lock into the drm_ioctl function itself makes sure we blame the right subsystem and it gets us one step closer to eliminating the locked version of fops->ioctl. Since drm_ioctl does not require the lock itself, we only need to hold it while calling the specific handler. The 32 bit conversion handlers do not interact with any other code, so they don't need the BKL here either and can just call drm_ioctl. As a bonus, this cleans up all the other users of drm_ioctl which now no longer have to find the inode or call lock_kernel. [airlied: squashed the non-driver bits of the second patch in here, this provides the flag for drivers to use to select unlocked ioctls - but doesn't modify any drivers].

2009-12-16drm/ttm: Fix potential ttm_mem_evict_first races.Thomas Hellstrom
1) The function was previously called with a potentially empty LRU list which would have lead to an OOPS or servere corruption. 2) In rare cases, after reservation has succeeded, another process may already have evicted it or even pinned it.

2009-12-15drm/vmwgfx: Add DRM driver for VMware Virtual GPUJakob Bornecrantz
This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA. The driver is under staging the same as Nouveau and Radeon KMS. Hopefully the 2D ioctls are bug free and don't need changing, so that part of the API should be stable. But there there is a pretty big chance that the 3D API will change in the future.

2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA. This driver is a KMS-based driver and requires a compatible nouveau userspace libdrm and nouveau X.org driver. This driver requires firmware files not available in this kernel tree, interested parties can find them via the nouveau project git archive. This driver is reverse engineered, and is in no way supported by nVidia. Support for nearly the complete range of nvidia hw from nv04->g80 (nv50) is available, and the kms driver should support driving nearly all output types (displayport is under development still) along with supporting suspend/resume. This work is all from the upstream nouveau project found at nouveau.freedesktop.org.

2009-12-11drm/ttm: Convert ttm_buffer_object_init to use ttm_placementJerome Glisse
Convert ttm_buffer_object_init to use struct ttm_placement and rename to ttm_bo_init for consistency with function naming. This allow to give more complex placement at buffer creation. For instance you ask to allocate bo into vram first but if there is not enough vram you can give system as a second possible placement. It also allow to create buffer in a specific range. Also rename ttm_buffer_object_validate to ttm_bo_validate. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>

2009-12-10Merge remote branch 'korg/drm-radeon-next' of into drm-linusDave Airlie
This merges some TTM overhauls to allow us to do better object placement for certain radeon GPUs that need scanout+cursor within range of each other, along with an API change to not return ERESTART to userspace, but to use ERESTARTSYS properly internally and have it convert to EINTR and catch that correctly. Also lots of radeon fixes across the board.

2009-12-10drm/radeon: Remove tests for -ERESTART from the TTM code.Thomas Hellstrom
Also sets affected TTM calls up to not wait interruptible, since that would cause an in-kernel spin until the TTM call succeeds, since the Radeon code does not return to user-space when a signal is received. Modifies interruptible fence waits to return -ERESTARTSYS rather than -EBUSY when interrupted by a signal, since that's the (yet undocumented) semantics required by the TTM sync object hooks.

2009-12-10drm/ttm: Rework validation & memory space allocation (V3)Jerome Glisse
This change allow driver to pass sorted memory placement, from most prefered placement to least prefered placement. In order to avoid long function prototype a structure is used to gather memory placement informations such as range restriction (if you need a buffer to be in given range). Range restriction is determined by fpfn & lpfn which are the first page and last page number btw which allocation can happen. If those fields are set to 0 ttm will assume buffer can be put anywhere in the address space (thus it avoids putting a burden on the driver to always properly set those fields). This patch also factor few functions like evicting first entry of lru list or getting a memory space. This avoid code duplication. V2: Change API to use placement flags and array instead of packing placement order into a quadword. V3: Make sure we set the appropriate mem.placement flag when validating or allocation memory space. [Pending Thomas Hellstrom further review but okay from preliminary review so far]. Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
