Although we can do a good job of reading out hardware state, the
graphics firmware may have programmed the watermarks in a creative way
that doesn't match how i915 would have chosen to program them. We
shouldn't trust the firmware's watermark programming, but should rather
re-calculate how we think WM's should be programmed and then shove those
values into the hardware.
We can do this pretty easily by creating a dummy top-level state,
running it through the check process to calculate all the values, and
then just programming the watermarks for each CRTC.
v2: Move watermark sanitization after our BIOS fb reconstruction; the
watermark calculations that we do here need to look at pstate->fb,
which isn't setup yet in intel_modeset_setup_hw_state(), even
though we have an enabled & visible plane.
v3:
- Don't move 'active = optimal' watermark assignment; we just undo
that change in the next patch anyway. (Ville)
- Move atomic helper locking fix to separate patch. (Maarten)
v4:
- Grab connection_mutex before calling atomic helper to duplicate
state. The connector loop inside the helper will throw a WARN
if we don't hold something to protect the connector list (and the
helper itself doesn't try to lock the list).
- Make failure to calculate watermarks for inherited state a WARN()
since it probably indicates a serious problem in either our state
readout code or our watermark code for this platform.

Our low-level watermark calculation functions don't get called when the
CRTC is disabled or the relevant plane is invisible, so they should
never see a zero htotal or zero bpp. However add some checks to ensure
this is true so that we don't wind up dividing by zero if we make a
mistake elsewhere in the driver (which the atomic watermark series has
revealed we might be).

When watermark calculation was moved up to the atomic check phase, the
code was updated to calculate based on in-flight atomic state rather
than already-committed state. However the hsw_compute_linetime_wm()
didn't get updated and continued to pull values out of the
currently-committed CRTC state. On platforms that call this function
(HSW/BDW only), this will cause problems when we go to enable the CRTC
since we'll pull the current mode (off) rather than the mode we're
calculating for and wind up with a divide by zero error.
This was an oversight in commit:

drm/i915: Calculate ILK-style watermarks during atomic check (v3)

Plane state objects contain two copies of src/dest coordinates: the
original (requested by userspace) coordinates in the base
drm_plane_state object, and a second, clipped copy (i.e., what we
actually want to program to the hardware) in intel_plane_state. We've
only been setting up the former set of values during boot time FB
reconstruction, but we should really be initializing both.
Note that the code here probably still needs some more work since we
make a lot of assumptions about how the BIOS programmed the hardware
that may not always be true, especially on gen9+; e.g.,
* Primary plane might not be positioned at 0,0
* Primary plane could have been rotated by the BIOS
* Primary plane might be scaled
* The BIOS fb might be a single "extended mode" FB that spans
multiple displays.
* ...etc...

Following a GPU reset, we may leave the context in a poorly defined
state, and reloading from that context will leave the GPU flummoxed. For
secondary contexts, this will lead to that context being banned - but
currently it is also causing the default context to become banned,
leading to turmoil in the shared state.
This is a regression from

GuC supports different scheduling policies for its four internal
queues. Currently these have been set to the same default values
as KMD_NORMAL queue.
Particularly POLICY_MAX_NUM_WI is set to 15 to match GuC internal
maximum submit queue numbers to avoid an out-of-space problem.
This value indicates max number of work items allowed to be queued
for one DPC process. A smaller value will let GuC schedule more
frequently while a larger number may increase chances to optimize
cmds (such as collapse cmds from same lrc) with risks that keeps
CS idle.

a chunk of memory created by driver to share with GuC. Its members
are usually addresses telling where GuC to access them, including

This is the first patch of a series to enable GuC ADS. For now, we

If the system has no available swap pages, we cannot make forward
progress in the shrinker by releasing active pages, only by releasing
purgeable pages which are immediately reaped. Take total_swap_pages into
account when counting up available objects to be shrunk and subsequently
shrinking them. By doing so, we avoid unbinding objects that cannot be
shrunk and so wasting CPU cycles flushing those objects from the GPU to
the system and then immediately back again (as they will more than
likely be reused shortly after).
Based on a patch by Akash Goel.
v2: frontswap registers extra swap pages available for the system, so it
is already include in the count of available swap pages.
v3: Use get_nr_swap_pages() to query the currently available amount of
swap space. This should also stop us from shrinking the GPU buffers if
we ever run out of swap space. Though at that point, we would expect the
oom-notifier to be running and failing miserably...
