the code always returns ret regardless, so if(ret) check is unnecessary. v2: fixed up the spelling. Signed-off-by: Greg Dietsche <Gregory.Dietsche@cuw.edu> Reviewed-by: Nicolas Kaiser <nikai@nikai.net> Signed-off-by: Dave Airlie <airlied@redhat.com>
2011-02-07drm: rework PCI/platform driver interface.Dave Airlie
This abstracts the pci/platform interface out a step further, we can go further but this is far enough for now to allow USB to be plugged in. The drivers now just call the init code directly for their device type. Signed-off-by: Dave Airlie <airlied@redhat.com>

2010-09-16drm: use noop_llseekArnd Bergmann
The drm device drivers currently allow seeking on the character device but never care about the actual file position. When we change the default llseek operation to be no_llseek, calling llseek on a drm device would return an error condition, which is an API change. Explicitly setting noop_llseek lets us keep the current API. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: David Airlie <airlied@linux.ie> Cc: dri-devel@lists.freedesktop.org

2010-08-17drm: block userspace under allocating buffer and having drivers overwrite it ↵Dave Airlie
(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>

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].

2009-03-13drm: Use resource_size_t for drm_get_resource_{start, len}Benjamin Herrenschmidt
The DRM uses its own wrappers to obtain resources from PCI devices, which currently convert the resource_size_t into an unsigned long. This is broken on 32-bit platforms with >32-bit physical address space. This fixes them, along with a few occurences of unsigned long used to store such a resource in drivers.

2008-07-14drm: reorganise drm tree to be more future proof.Dave Airlie
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>
