- more chv code, now almost complete (tons of different people)
- refactoring and improvements for drm_irq.c merged through drm-intel-next
- g4x/ilk reset improvements (Ville)
- removal of encoder->mode_set
- moved audio state tracking into pipe_config
- shuffled fb pinning out of the platform crtc modeset callbacks into core code

This should be called by application level drivers before and
after mode setting, since on many devices the vertical blank
counter is reset at that time. Internally, the DRM snapshots
the last vblank count when the ioctl is called with the
_DRM_PRE_MODESET command, so that the counter won't go backwards
(which is dealt with when _DRM_POST_MODESET is used).
This was only used for user-mode-settind drivers around
modesetting changes to allow the kernel to update the vblank
interrupt after mode setting, since on many devices the vertical
blank counter is reset to 0 at some point during modeset. Modern
drivers should not call this any more since with kernel mode
setting it is a no-op.

* Save all Gunit registers that may be lost after a D3 and a subsequent

* registers in the following way:
* - Driver: saved/restored by the driver
* - Punit : saved/restored by the Punit firmware
* - No, w/o marking: no need to save/restore, since the register is R/O or
* used internally by the HW in a way that doesn't depend
* keeping the content across a suspend/resume.
* - Debug : used for debugging
*
* We save/restore all registers marked with 'Driver', with the following
* exceptions:
* - Registers out of use, including also registers marked with 'Debug'.
* These have no effect on the driver's operation, so we don't save/restore
* them to reduce the overhead.
* - Registers that are fully setup by an initialization function called from
* the resume path. For example many clock gating and RPS/RC6 registers.
* - Registers that provide the right functionality with their reset defaults.
*
* TODO: Except for registers that based on the above 3 criteria can be safely
* ignored, we save/restore all others, practically treating the HW context as
* a black-box for the driver. Further investigation is needed to reduce the
* saved/restored registers even further, by following the same 3 criteria.

/**
* Creates a new mm object that wraps some normal memory from the process
* context - user memory.
*
* We impose several restrictions upon the memory being mapped
* into the GPU.
* 1. It must be page aligned (both start/end addresses, i.e ptr and size).
* 2. It cannot overlap any other userptr object in the same address space.
* 3. It must be normal system memory, not a pointer into another map of IO
* space (e.g. it must not be a GTT mmapping of another object).
* 4. We only allow a bo as large as we could in theory map into the GTT,
* that is we limit the size to the total size of the GTT.
* 5. The bo is marked as being snoopable. The backing pages are left
* accessible directly by the CPU, but reads and writes by the GPU may
* incur the cost of a snoop (unless you have an LLC architecture).
*
* Synchronisation between multiple users and the GPU is left to userspace
* through the normal set-domain-ioctl. The kernel will enforce that the
* GPU relinquishes the VMA before it is returned back to the system
* i.e. upon free(), munmap() or process termination. However, the userspace
* malloc() library may not immediately relinquish the VMA after free() and
* instead reuse it whilst the GPU is still reading and writing to the VMA.
* Caveat emptor.
*
* Also note, that the object created here is not currently a "first class"
* object, in that several ioctls are banned. These are the CPU access
* ioctls: mmap(), pwrite and pread. In practice, you are expected to use
* direct access via your pointer rather than use those ioctls.
*
* If you think this is a good interface to use to pass GPU memory between
* drivers, please use dma-buf instead. In fact, wherever possible use
* dma-buf instead.
