We need to get the silicon revision id before we parse
the firmware in order to load the correct gpu info firmware
for raven2 variants.

pm_runtime_get_sync() increments the runtime PM usage counter even
the call returns an error code. Thus a pairing decrement is needed

When calling OpenCL clEnqueueSVMMigrateMem() on a region of memory that
is backed by pte_none() or zero pages, migrate_vma_setup() will fill the
source PFN array with an entry indicating the source page is zero.
Use this to optimize migration to device private memory by allocating
GPU memory and zero filling it instead of failing to migrate the page.

In nouveau_dmem_init(), a number of struct nouveau_dmem_chunk are allocated
and put on the dmem->chunk_empty list. Then in nouveau_dmem_pages_alloc(),
a nouveau_dmem_chunk is removed from the list and GPU memory is allocated.
However, the nouveau_dmem_chunk is never removed from the chunk_empty
list nor placed on the chunk_free or chunk_full lists. This results
in only one chunk ever being actually used (2MB) and quickly leads to
migration to device private memory failures.
Fix this by having just one list of free device private pages and if no
pages are free, allocate a chunk of device private pages and GPU memory.

Currently, the nv50_mstc_mode_valid() function is happy to take any and
all modes, even the ones we can't actually support sometimes like
interlaced modes.
Luckily, the only difference between the mode validation that needs to
be performed for MST vs. SST is that eventually we'll need to check the
minimum PBN against the MSTB's full PBN capabilities (remember-we don't
care about the current bw state here). Otherwise, all of the other code
can be shared.
So, we move all of the common mode validation in
nouveau_connector_mode_valid() into a separate helper,
nv50_dp_mode_valid(), and use that from both nv50_mstc_mode_valid() and
nouveau_connector_mode_valid(). Note that we allow for returning the
calculated clock that nv50_dp_mode_valid() came up with, since we'll
eventually want to use that for PBN calculation in
nv50_mstc_mode_valid().

This just limits the BPC for MST connectors to a maximum of 8 from
nv50_mstc_get_modes(), instead of doing so during
nv50_msto_atomic_check(). This doesn't introduce any functional changes
yet (other then userspace now lying about the max bpc, but we can't
support that yet anyway so meh). But, we'll need this in a moment so
that we can share mode validation between SST and MST which will fix
some real world issues.

We advertise being able to set interlaced modes, so let's actually make
sure to do that. Otherwise, we'll end up hanging the display engine due
to trying to set a mode with timings adjusted for interlacing without
telling the hardware it's actually an interlaced mode.

Right now, we make the mistake of allowing interlacing on all
connectors. Nvidia hardware does not always support interlacing with DP
though, so we need to make sure that we don't allow interlaced modes to
be set in such situations as otherwise we'll end up accidentally hanging
the display HW.
This fixes some hangs with Turing, which would be caused by attempting
to set an interlaced mode on hardware that doesn't support it. This
patch likely fixes other hardware hanging in the same way as well.
Note that we say we probe PIOR caps, but they don't actually have any
interlacing caps. So, the get_caps() function for PIORs just sets
interlacing support to true.
Changes since v1:
* Actually probe caps correctly this time, both on EVO and NVDisplay.
Changes since v2:
* Fix probing for < GF119
* Use vfunc table, in prep for adding more caps in the future.

We'll need the core channel initialized and ready by the time that we
start creating modesetting objects, so that we can call the
NV507D_GET_CAPABILITIES method to make the hardware expose it's
modesetting capabilities for later probing.
So, when loading the driver prepare the core channel from within
nouveau_display_create(). Everywhere else, we initialize the core
channel during resume.

Since the commit 742db30c4ee6 ("drm/nouveau: Add HD-audio component
notifier support"), the nouveau driver notifies and pokes the HD-audio
HPD and ELD via audio component, but this seems broken. The culprit
is the naive assumption that crtc->index corresponds to the HDA pin.
Actually this rather corresponds to the MST dev_id (alias "pipe" in
the audio component framework) while the actual port number is given
from the output ior id number.
This patch corrects the assignment of port and dev_id arguments in the
audio component ops to recover from the HDMI/DP audio regression.

When memory is migrated to the GPU, it is likely to be accessed by GPU
code soon afterwards. Instead of waiting for a GPU fault, map the
migrated memory into the GPU page tables with the same access permissions
as the source CPU page table entries. This preserves copy on write
semantics.

The vma field of struct nouveau_framebuffer is a special field for the

drm_framebuffer.
