2007-10-19Use helpers to obtain task pid in printksPavel Emelyanov
The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

2007-10-15drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt
The data is now in kernel space, copied in/out as appropriate according to t This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DR is lost. Signed-off-by: Dave Airlie <airlied@linux.ie>
2007-10-15drm: Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt
As a fallout, replace filp storage with file_priv storage for "unique identifier of a client" all over the DRM. There is a 1:1 mapping, so this should be a noop. This could be a minor performance improvement, as everyth on Linux dereferenced filp to get file_priv anyway, while only the mmap ioct went the other direction.

2007-10-15drm: Remove DRM_ERR OS macro.Eric Anholt
This was used to make all ioctl handlers return -errno on linux and errno on *BSD. Instead, just return -errno in shared code, and flip sign on return f shared code to *BSD code. Signed-off-by: Dave Airlie <airlied@linux.ie>

some drivers still todo. Signed-off-by: Dave Airlie <airlied@linux.ie>
2007-07-11drm: remove a bunch of typedefs on the userspace interfaceDave Airlie
This moves a bunch of typedefs into a !defined __KERNEL__ to keep userspace API compatiblity, it changes all internal usages to structs/enum/unions. Signed-off-by: Dave Airlie <airlied@linux.ie>
2007-03-23drm: fix driver deadlock with AIGLX and reclaim_buffers_lockedThomas Hellstrom
Bugzilla Bug #9457 Add refcounting of user waiters to the DRM hardware lock, so that we can use DRM_LOCK_CONT flag more conservatively. Also add a kernel waiter refcount that if nonzero transfers the lock for the kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager Signed-off-by: Dave Airlie <airlied@linux.ie>

2006-01-02drm: major update from CVS for radeon and coreDave Airlie
This patch pull in a lot of changes from CVS to the main core DRM, and updates the radeon driver to 1.21.0 that supports r300 texrect and radeon card type ioctl. Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-11-24drm: fix quiescent lockingDave Airlie
A fix for a locking bug which is triggered when a client tries to lock with flag DMA_QUIESCENT (typically the X server), but gets interrupted by a signal. The locking IOCTL should then return an error, but if DMA_QUIESCENT succeeds it returns 0, and the client falsely thinks it has the lock. In addition The client waits for DMA_QUISCENT and possibly DMA_READY without having the lock. From: Thomas Hellstrom Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-09-25drm: lindent the drm directory.Dave Airlie
I've been threatening this for a while, so no point hanging around. This lindents the DRM code which was always really bad in tabbing department. I've also fixed some misnamed files in comments and removed some trailing whitespace. Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-07-07drm: misc cleanupDave Airlie
This patch contains the following cleanups: - make needlessly global functions static - remove the following unused global functions: - drm_fops.c: drm_read - i915_dma.c: i915_do_cleanup_pageflip Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
