* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-141-540/+0
| | | | | | | | | | | | | | 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>
* drm: only trust core drm ioctls - driver ioctls are a mess.Dave Airlie2008-06-201-4/+3
| | | | | | So driver ioctls need a full auditing before we can make this change. Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: use drms ioctl cmd not what we get passed from userspace.Johannes Weiner2008-06-131-0/+2
| | | | | | | | | | | This enforces us to use the drm ioctl types so read/write works correctly and not believe what userspace tells us. It does this hopefully without breaking the drm api. Fixes bug from thread: BUG: unable to handle kernel NULL pointer dereference (drm_getunique) Signed-off-by: Dave Airlie <airlied@redhat.com>
* drm: reorganise minor number handling using backported modesetting code.Dave Airlie2008-04-261-32/+28

* drm: add _DRM_DRIVER flag, and re-order unload.Dave Airlie2008-02-071-6/+7
| | | | | | | | Allow drivers to addmaps that won't be removed by lastclose or unload. The unload needs to be re-ordered to avoid removing the hashs before the driver has removed the final maps. Signed-off-by: Dave Airlie <airlied@linux.ie>
* drm: move drm_mem_init to proper place in startup sequenceDave Airlie2008-02-071-2/+2
| | | | | | For TTM this needs to be called later. Signed-off-by: Dave Airlie <airlied@linux.ie>
* drm: update DRM sysfs supportJesse Barnes2008-02-071-5/+5
| | | | | | | | | Make DRM devices use real Linux devices instead of class devices, which are going away. While we're at it, clean up some of the interfaces to take struct drm_device * or struct device * and use the global drm_class where needed instead of passing it around.

* Use helpers to obtain task pid in printksPavel Emelyanov2007-10-191-1/+1
| | | | | | | | | | | | | | | | 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.

* drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE.Eric Anholt2007-10-151-75/+92
| | | | | | | | | 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>
* drm: Replace filp in ioctl arguments with drm_file *file_priv.Eric Anholt2007-10-151-14/+13
| | | | | | | | | | 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.

* [PATCH] mark struct file_operations const 3Arjan van de Ven2007-02-121-1/+1
| | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* drm: Add support for tracking drawable information to core=?utf-8?q?Michel_D=C3=A4nzer?=2006-12-071-0/+2
| | | | | | | | | | | | | | Actually make the existing ioctls for adding and removing drawables do something useful, and add another ioctl for the X server to update drawable information. The only kind of drawable information tracked so far is cliprects. Only reallocate cliprect memory if the number of cliprects changes.

* drm: rename driver hooks more understandablyDave Airlie2005-11-101-13/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Rename the driver hooks in the DRM to something a little more understandable: preinit -> load postinit -> (removed) presetup -> firstopen postsetup -> (removed) open_helper -> open prerelease -> preclose free_filp_priv -> postclose pretakedown -> lastclose postcleanup -> unload release -> reclaim_buffers_locked version -> (removed) postinit and version were replaced with generic code in the Linux DRM (drivers now set their version numbers and description in the driver structure, like on BSD). postsetup wasn't used at all. Fixes the savage hooks for initializing and tearing down mappings at the right times. Testing involved at least starting X, running glxgears, killing glxgears, exiting X, and repeating.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-171-0/+531
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!
