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>

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.

2007-07-17drm: convert drm context code to use Linux idrDave Airlie
This converts the drm context allocator to an idr, using the new idr interface features from Kristian. Fixes from Kristian Hoegsberg <krh@redhat.com> Signed-off-by: Dave Airlie <airlied@linux.ie>
2007-07-11drm: detypedeffing continues...Dave Airlie

2007-07-11drm: remove drm_file_t, drm_device_t and drm_head_t typedefsDave Airlie
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>
2007-07-11drm: cleanup use of Linux list handling macrosDave Airlie
This makes the drms use of the list handling macros a lot cleaner and more along the lines of how they should be used and uses them in some more places. Signed-off-by: Dave Airlie <airlied@linux.ie>

2006-01-02drm: proper fix for drm_contextDave Airlie
Bad patch in last version Signed-off-by: Dave Airlie <airlied@linux.ie>

2005-09-30drm: fix all sparse warning on 32-bit x86Dave Airlie
Finally cleaned up the sparse warnings for the drm. 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>
2005-09-05drm: small cleanupsDave Airlie
This patch contains the following small cleanups: - make two needlessly global functions static - drm_sysfs.c: every file should #include the header with the prototypes of the global functions it is offering Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Dave Airlie <airlied@linux.ie>
2005-08-05drm: updated DRM map patch for 32/64 bit systemsDave Airlie
I basically combined Paul's patches with additions that I had made for PCI scatter gather. I also tried more carefully to avoid problems with the same token assigned multiple times while trying to use the base address in the token if possible to gain as much backward compatibility as possible for broken DRI clients.

2005-08-05drm: copy the right data back to userspace for getreserved contexts ioctlDave Airlie
This fixes the information copied back to userspace by the get reserved contexts ioctl. From: Egbert Eich <eich@suse.de> 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>
2005-06-23drm: 32/64-bit DRM ioctl compatibility patchDave Airlie
The patch is against a 2.6.11 kernel tree. I am running this with a 32-bit X server (compiled up from X.org CVS as of a couple of weeks ago) and 32-bit DRI libraries and clients. All the userland stuff is identical to what I am using under a 32-bit kernel on my G4 powerbook (which is a 32-bit machine of course). I haven't tried compiling up a 64-bit X server or clients yet. In the compatibility routines I have assumed that the kernel can safely access user addresses after set_fs(KERNEL_DS). That is, where an ioctl argument structure contains pointers to other structures, and those other structures are already compatible between the 32-bit and 64-bit ABIs (i.e. they only contain things like chars, shorts or ints), I just check the address with access_ok() and then pass it through to the 64-bit ioctl code. I believe this approach may not work on sparc64, but it does work on ppc64 and x86_64 at least. One tricky area which may need to be revisited is the question of how to handle the handles which we pass back to userspace to identify mappings. These handles are generated in the ADDMAP ioctl and then passed in as the offset value to mmap. However, offset values for mmap seem to be generated in other ways as well, particularly for AGP mappings. The approach I have ended up with is to generate a fake 32-bit handle only for _DRM_SHM mappings. The handles for other mappings (AGP, REG, FB) are physical addresses which are already limited to 32 bits, and generating fake handles for them created all sorts of problems in the mmap/nopage code. This patch has been updated to use the new compatibility ioctls. From: Paul Mackerras <paulus@samba.org> Signed-off-by: Dave Airlie <airlied@linux.ie>

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!
