2009-06-18drm: Remove memory debugging infrastructure.Eric Anholt
It hasn't been used in ages, and having the user tell your how much memory is being freed at free time is a recipe for disaster even if it was ever used. Signed-off-by: Eric Anholt <eric@anholt.net>
2009-06-15debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem.GeunSik Lim
Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/" directory name to mount debugfs filesystem for ftrace according to ./Documentation/tracers/ftrace.txt file. And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is existed in kernel source like ftrace, DRM, Wireless, Documentation, Network[sky2]files to mount debugfs filesystem. debugfs means debug filesystem for debugging easy to use by greg kroah hartman. "/sys/kernel/debug/" name is suitable as directory name of debugfs filesystem. - debugfs related reference: http://lwn.net/Articles/334546/ Fix inconsistency of directory name to mount debugfs filesystem. * From Steven Rostedt - find_debugfs() and tracing_files() in this patch.

2009-05-20drm: Copy back ioctl data to userspace regardless of return code.Michel Dänzer
Fixes a regression from commit 9d5b3ffc42f7820e8ee07705496955e4c2c38dd9 ('drm: fixup some of the ioctl function exit paths'): The vblank ioctl needs to update the userspace parameters when interrupted by a signal, which was prevented by the return code check. This could cause the X server to hang in drmWaitVBlank(). Signed-off-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>
2009-04-24drm: add control node checks missing from kms mergeJonas Bonn
This line that checks the DRM_CONTROL_ALLOW flag was missed from the KMS merge. Re-add the check on the IOCTL, as this is currently the only use of this flag. Signed-off-by: Jonas Bonn <jonas@southpole.se> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-03-29drm: Use a little stash on the stack to avoid kmalloc in most DRM ioctls.Eric Anholt
The kmalloc was taking up about 1.5% of the CPU on an ioctl-heavy workload (x11perf -aa10text on 965). Initial results look like they have a corresponding improvement in performance for aa10text, but more numbers might not hurt. Thanks to ajax for pointing out this performance regression I'd introduced back in 2007.

2009-03-13drm: Convert proc files to seq_file and introduce debugfsBen Gamari
The old mechanism to formatting proc files is extremely ugly. The seq_file API was designed specifically for cases like this and greatly simplifies the process. Also, most of the files in /proc really don't belong there. This patch introduces the infrastructure for putting these into debugfs and exposes all of the proc files in debugfs as well. This contains the i915 hooks rewrite as well, to make bisectability better.

2009-03-13drm: claim PCI device when running in modesetting mode.Kristian Høgsberg
Under kernel modesetting, we manage the device at all times, regardless of VT switching and X servers, so the only decent thing to do is to claim the PCI device. In that case, we call the suspend/resume hooks directly from the pci driver hooks instead of the current class device detour.

2009-03-13drm: Split drm_map and drm_local_mapBenjamin Herrenschmidt
Once upon a time, the DRM made the distinction between the drm_map data structure exchanged with user space and the drm_local_map used in the kernel. For some reasons, while the BSD port still has that "feature", the linux part abused drm_map for kernel internal usage as the local map only existed as a typedef of the struct drm_map. This patch fixes it by declaring struct drm_local_map separately (though its content is currently identical to the userspace variant), and changing the kernel code to only use that, except when it's a user<->kernel interface (ie. ioctl). This allows subsequent changes to the in-kernel format I've also replaced the use of drm_local_map_t with struct drm_local_map in a couple of places. Mostly by accident but they are the same (the former is a typedef of the later) and I have some remote plans and half finished patch to completely kill the drm_local_map_t typedef so I left those bits in.

2009-01-19drm: fix leak of device mappings since multi-master changes.Dave Airlie
Device maps now contain a link to the master that created them, so when cleaning up the master, remove any maps that are connected to it. Also delete any remaining maps at driver unload time. Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-01-07drm: fix ordering of driver unload vs agp unload.Dave Airlie

2008-12-29drm: drop DRM_IOCTL_MODE_REPLACEFB, add+remove works just as well.Kristian H�gsberg
The replace fb ioctl replaces the backing buffer object for a modesetting framebuffer object. This can be acheived by just creating a new framebuffer backed by the new buffer object, setting that for the crtcs in question and then removing the old framebuffer object.

2008-12-29drm: sanitise drm modesetting API + remove unused hotplugJakob Bornecrantz

2008-12-29DRM: add mode setting supportDave Airlie
Add mode setting support to the DRM layer. This is a fairly big chunk of work that allows DRM drivers to provide full output control and configuration capabilities to userspace. It was motivated by several factors: - the fb layer's APIs aren't suited for anything but simple configurations - coordination between the fb layer, DRM layer, and various userspace drivers is poor to non-existent (radeonfb excepted) - user level mode setting drivers makes displaying panic & oops messages more difficult - suspend/resume of graphics state is possible in many more configurations with kernel level support This commit just adds the core DRM part of the mode setting APIs. Driver specific commits using these new structure and APIs will follow.

2008-12-29drm: move to kref per-master structures.Dave Airlie
This is step one towards having multiple masters sharing a drm device in order to get fast-user-switching to work. It splits out the information associated with the drm master into a separate kref counted structure, and allocates this when a master opens the device node. It also allows the current master to abdicate (say while VT switched), and a new master to take over the hardware. It moves the Intel and radeon drivers to using the sarea from within the new master structures. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-12-29drm: cleanup exit path for module unloadDave Airlie

2008-11-25drm: move drm vblank initialization/cleanup to driver load/unloadKeith Packard

2008-11-11drm/i915: Filter pci devices based on PCI_CLASS_DISPLAY_VGADave Airlie
This fixes hangs on 855-class hardware by avoiding double attachment of the driver due to the stub second head device having the same pci id as the real device. Other DRM drivers probably want this treatment as well, but I'm applying it just to this one for safety. But we should clean up the drm_pciids.h mess now so that each driver has its own pci id list header in its own directory. Lets do that in the next release.

2008-10-18drm: Add GEM ("graphics execution manager") to i915 driver.Eric Anholt
GEM allows the creation of persistent buffer objects accessible by the graphics device through new ioctls for managing execution of commands on the device. The userland API is almost entirely driver-specific to ensure that any driver building on this model can easily map the interface to individual driver requirements. GEM is used by the 2d driver for managing its internal state allocations and will be used for pixmap storage to reduce memory consumption and enable zero-copy GLX_EXT_texture_from_pixmap, and in the 3d driver is used to enable GL_EXT_framebuffer_object and GL_ARB_pixel_buffer_object.

2008-10-18drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes
Previously, drivers supporting vblank interrupt waits would run the interrupt all the time, or all the time that any 3d client was running, preventing the CPU from sleeping for long when the system was otherwise idle. Now, interrupts are disabled any time that no client is waiting on a vblank event. The new method uses vblank counters on the chipsets when the interrupts are turned off, rather than counting interrupts, so that we can continue to present accurate vblank numbers.

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>
