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.

The driver would like to map IO space directly for copying data in when appropriate, to avoid CPU cache flushing for streaming writes. kmap_atomic_pfn lets us avoid IPIs associated with ioremap for this process.

GEM needs to create shmem files to back buffer objects. Though currently creation of files for objects could have been driven from userland, the modesetting work will require allocation of buffer objects before userland is running, for boot-time message display.

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.

Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

[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: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave 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.

Fix the SIS DRM memory allocator if the SIS FB built as a module. The SIS DRM code initialises the mm allocation hooks, but _only_ if the SIS FB is not built as a module because it depends on CONFIG_FB_SIS, and that's unset if the SIS FB is not built in. It must check CONFIG_FB_SIS_MODULE as well.
