Adds code to set up fence registers at execbuf time on pre-965 chips as necessary. Also fixes up a few bugs in the pre-965 tile register support (get_order != ffs). The number of fences available to the kernel defaults to the hw limit minus 3 (for legacy X front/back/depth), but a new parameter allows userspace to override that as needed.

This is an initial patch to do support for objects which needs physical contiguous main ram, cursors and overlay registers on older chipsets. These objects are bound on cursor bin, like pinning, and we copy the data to/from the backing store object into the real one on attach/detach. notes: possible over the top in attach/detach operations. no overlay support yet.

This commit adds i915 driver support for the DRM mode setting APIs. Currently, VGA, LVDS, SDVO DVI & VGA, TV and DVO LVDS outputs are supported. HDMI, DisplayPort and additional SDVO output support will follow. Support for the mode setting code is controlled by the new 'modeset' module option. A new config option, CONFIG_DRM_I915_KMS controls the default behavior, and whether a PCI ID list is built into the module for use by user level module utilities. Note that if mode setting is enabled, user level drivers that access display registers directly or that don't use the kernel graphics memory manager will likely corrupt kernel graphics memory, disrupt output configuration (possibly leading to hangs and/or blank displays), and prevent panic/oops messages from appearing. So use caution when enabling this code; be sure your user level code supports the new interfaces. A new SysRq key, 'g', provides emergency support for switching back to the kernel's framebuffer console; which is useful for testing.

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: NDave Airlie <airlied@redhat.com>

On PAE systems, GEM allocates pages using shmem, and passes these pages to be bound into AGP, however the AGP interfaces + the x86 set_memory interfaces all take unsigned long not dma_addr_t. The initial fix for this was a mess, so we need to do this correctly for 2.6.29. Signed-off-by: NDave Airlie <airlied@redhat.com>

The pipestat fields affect reporting of all vblank-related interrupts, so we have to reset them during the irq_handler, and while enabling vblank interrupts. Otherwise, if a pipe status field had been set to non-zero before enabling reporting, we would never see an interrupt again. This patch adds i915_enable_pipestat and i915_disable_pipestat to abstract out the steps needed to change the reported interrupts.

When userland detected that this ioctl was supported (by version number check), it used it in a racy way -- dispatch delayed swap, wait for vblank, continue rendering. As there was no mechanism for it to wait for the swap to finish, sometimes it would render before the swap and garbage would be displayed on the screen. By removing the ioctl and returning -EINVAL, userland returns to its previous, correct rendering path of waiting for a vblank then dispatching a swap. The only path that could have used this ioctl correctly was page flipping, which relied on only one client running and emitting wait-for-vblank-before-rendering in the command stream. That path also falls back correctly, at the performance cost of not being able to queue up rendering before the flip occurs.

Impact: optimize/clean-up the IO mapping implementation of the i915 DRM driver Switch the i915 device aperture mapping to the io-mapping interface, taking advantage of the cleaner API to extend it across all of the mapping uses, including both pwrite and relocation updates. This dramatically improves performance on 64-bit kernels which were using the same slow path as 32-bit non-HIGHMEM kernels prior to this patch.

To synchronize clip lists with the X server, the DRM lock must be held while looking at drawable clip lists. To synchronize with other ring access, the ring mutex must be held while inserting commands into the ring. Failure to do the first resulted in easy visual corruption when moving windows, and the second could have corrupted the ring with DRI2. Grabbing the DRM lock involves using the DRM tasklet mechanism, grabbing the ring mutex means potentially sleeping. Deal with both of these by always running the tasklet from a work handler. Also, protect from clip list changes since the vblank request was queued by making sure the window has at least one rectangle while looking inside, preventing oopses .

In the conversion for GEM, we had stopped using the hardware lock to protect ring usage, since it was all internal to the DRM now. However, some paths weren't converted to using struct_mutex to prevent multiple threads from concurrently working on the ring, in particular between the vblank swap handler and ioctls.

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.

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.

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: NDave Airlie <airlied@redhat.com>
