* Merge remote branch 'anholt/drm-intel-next' into drm-linusDave Airlie2009-12-07
|\ | | | | | | | | | | | | | | | | | | | | This merges the upstream Intel tree and fixes up numerous conflicts due to patches merged into Linus tree later in -rc cycle. Conflicts: drivers/char/agp/intel-agp.c drivers/gpu/drm/drm_dp_i2c_helper.c drivers/gpu/drm/i915/i915_irq.c drivers/gpu/drm/i915/i915_suspend.c
| * drm: use page flip event to signal flip completionJesse Barnes2009-12-01
| | | | | | | | | | | | | | | | | | | | We don't actually know which frame number the flip will complete on, so userspace needs a specific flip notification to tell it when the last flip completed.

* | drm: Add dirty ioctl and propertyJakob Bornecrantz2009-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a ioctl and property to allow userspace to notify the kernel that a framebuffer has changed. Instead of snooping the command stream this allows finer grained tracking of which areas have changed. The primary user for this functionality is virtual hardware like the vmware svga device, but also Xen hardware likes to be notify. There is also real hardware like DisplayLink and DisplayPort that might take advantage of this ioctl.

* drm/kms: add page flipping ioctlKristian Høgsberg2009-11-17
| | | | | | | | | | | | | | | | This adds a page flipping ioctl to the KMS API. The ioctl takes an fb ID and a ctrc ID and flips the crtc to the given fb at the next vblank. The ioctl returns immediately but the flip doesn't happen until after any rendering that's currently queued up against the new framebuffer is done. After submitting a page flip, any execbuffer involving the old front buffer will block until the flip is completed. Optionally, a vblank event can be generated when the swap eventually happens.

* drm: Add async event synchronization for drmWaitVblankKristian Høgsberg2009-11-17
| | | | | | | | | | | | | | | | | This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm to return immediately and notify userspace when the specified vblank sequence happens by sending an event back on the drm fd. The event mechanism works with the other flags supported by the ioctls, specifically, the vblank sequence can be specified relatively or absolutely, and works for primary and seconday crtc. The signal field of the vblank request is used to provide user data, which will be sent back to user space in the vblank event.

* make drm headers use strict integer typesArnd Bergmann2009-03-26
| | | | | | | | | | | The drm headers are traditionally shared with BSD and could not use the strict linux integer types. This is over now, so we can use our own types now.

| | | | | | | | | | | Schedule a vblank signal, kill the process, and we'll go walking over freed memory. Given that no open-source userland exists using this, nor have I ever heard of a consumer, just let this code die.

* drm: drop DRM_IOCTL_MODE_REPLACEFB, add+remove works just as well.Kristian H�gsberg2008-12-29
| | | | | | | | | | | 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.

* DRM: add mode setting supportDave Airlie2008-12-29
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Add core support for mapping of GEM objects. Drivers should provide a vm_operations_struct if they want to support page faulting of objects.

* drm: move to kref per-master structures.Dave Airlie2008-12-29
| | | | | | | | | | | | | | | | 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>
* drm: Add GEM ("graphics execution manager") to i915 driver.Eric Anholt2008-10-17
| | | | | | | | | | | | | | | | 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.

* drm: Rework vblank-wait handling to allow interrupt reduction.Jesse Barnes2008-10-17
| | | | | | | | | | | | | | | 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.

* drm: reorganise drm tree to be more future proof.Dave Airlie2008-07-13
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>
