drm/ttm: export some functions useful to drivers using ttm
drm/radeon/kms/avivo: fix typo in new_pll module description
drm/radeon/kms: Convert radeon to new ttm_bo_init
drm/ttm: Convert ttm_buffer_object_init to use ttm_placement
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.
This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.
This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.

Convert ttm_buffer_object_init to use struct ttm_placement and
rename to ttm_bo_init for consistency with function naming. This
allow to give more complex placement at buffer creation. For
instance you ask to allocate bo into vram first but if there is
not enough vram you can give system as a second possible
placement. It also allow to create buffer in a specific range.
Also rename ttm_buffer_object_validate to ttm_bo_validate.

This merges some TTM overhauls to allow us to do better object placement
for certain radeon GPUs that need scanout+cursor within range of each other,
along with an API change to not return ERESTART to userspace, but to use
ERESTARTSYS properly internally and have it convert to EINTR and catch that
correctly. Also lots of radeon fixes across the board.
This add helper function to print information on eviction placements
and memory manager status when eviction fails to allocate memory
space.

On resume on my rv530 laptop surface cntl was left disabled, so

This checks if the surface regs are assigned to bos and reprograms
the surface registers on resume using the same path that clears

Also sets affected TTM calls up to not wait interruptible, since
that would cause an in-kernel spin until the TTM call succeeds, since
the Radeon code does not return to user-space when a signal is received.
Modifies interruptible fence waits to return -ERESTARTSYS rather than
-EBUSY when interrupted by a signal, since that's the (yet undocumented)
semantics required by the TTM sync object hooks.

This change allow driver to pass sorted memory placement,
from most prefered placement to least prefered placement.
In order to avoid long function prototype a structure is
used to gather memory placement informations such as range
restriction (if you need a buffer to be in given range).
Range restriction is determined by fpfn & lpfn which are
the first page and last page number btw which allocation
can happen. If those fields are set to 0 ttm will assume
buffer can be put anywhere in the address space (thus it
avoids putting a burden on the driver to always properly
set those fields).
This patch also factor few functions like evicting first
entry of lru list or getting a memory space. This avoid
code duplication.
V2: Change API to use placement flags and array instead
of packing placement order into a quadword.
V3: Make sure we set the appropriate mem.placement flag
when validating or allocation memory space.
[Pending Thomas Hellstrom further review but okay
from preliminary review so far].

Sometimes we will use a crtc for integerated LVDS, which is different with
that assigned by BIOS. If we want to get flicker-free transitions,
then we could read out the current state for it and set our current state
accordingly.
But it is true that if we aren't reading current state out, we do need
to turn everything off before modesetting. Otherwise the clocks can get very
angry and we get things worse than a flicker at boot.
In fact we also do the similar thing in UMS mode. We will disable all the
possible outputs/crtcs for the first modesetting.
So we disable all the possible outputs/crtcs before entering the KMS mode.
Before we configure connector/encoder/crtc, the function of
drm_helper_disable_unused_function can disable all the possible outputs/crtcs.
