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.

[Patch against drm-next. Consider this a trial balloon for our new Linux development model.] This is a big chunk of code. Separating it out makes it easier to change without churn on the main i915_drv.c file (and there will be churn as we fix bugs and add things like kernel mode setting). Also makes it easier to share this file with BSD. Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDave Airlie <airlied@redhat.com>

Previous attempts at interrupt mitigation had been foiled by i915_wait_irq's failure to update the sarea seqno value when the status page indicated that the seqno had already been passed. MSI support has been seen to cut CPU costs by up to 40% in some workloads by avoiding other expensive interrupt handlers for frequent graphics interrupts.

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>

Now that we're mapping registers in the DRM driver at load time, the driver actually checks the PCI ID, so we need to make sure the macros have all the right bits (and longer term use the DRM headers as the sole copy of the PCI & register definitions). This patch adds 945GME support to the DRM headers, fixing a regression reported in http://bugzilla.kernel.org/show_bug.cgi?id=10395.

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.
