drm/nouveau/bar/gm20b: Avoid BAR1 teardown during init

Writing the 0x1704 (BUS_BAR1_BLOCK) register causes the GPU to probe the
memory region at the programmed address. The result is an address decode
error in the external memory controller because address 0, which is what
is written to the register, is not designated as accessible to devices.

Avoid triggering DMA from the GPU by removing teardown of the BAR1.

drm/nouveau: Fix ordering between TTM and GEM release

When the last reference to a TTM BO is dropped, ttm_bo_release() will
acquire the DMA reservation object's wound/wait mutex while trying to
clean up (ttm_bo_cleanup_refs_or_queue() via ttm_bo_release()). It is
therefore essential that drm_gem_object_release() be called after the
TTM BO has been uninitialized, otherwise drm_gem_object_release() has
already destroyed the wound/wait mutex (via dma_resv_fini()).

drm/nouveau/prime: Extend DMA reservation object lock

Prior to commit 019cbd4a4feb ("drm/nouveau: Initialize GEM object before
TTM object"), the reservation object was locked across all of the buffer
object creation.

After splitting nouveau_bo_new() into separate nouveau_bo_alloc() and
nouveau_bo_init() functions, the reservation object is passed to the
latter, so the lock needs to be held across that function as well.

drm/nouveau: Fix fallout from reservation object rework

Commit 019cbd4a4feb ("drm/nouveau: Initialize GEM object before TTM
object") introduced a subtle change in how the buffer allocation size is
handled. Prior to that change, the size would get aligned to at least a
page, whereas after that change a non-page-aligned size would get passed
through unmodified. This ultimately causes a BUG_ON() to trigger in
drm_gem_private_object_init() and crashes the system.

Fix this by restoring the code that align the allocation size.

drm/nouveau/kms/nv50-: Don't create MSTMs for eDP connectors

On the ThinkPad P71, we have one eDP connector exposed along with 5 DP
connectors, resulting in a total of 11 TMDS encoders. Since the GPU on
this system is also capable of MST, we create an additional 4 fake MST
encoders for each DP port. Unfortunately, we also do this for the eDP
port as well, resulting in:

  1 eDP port: +1 TMDS encoder
              +4 DPMST encoders
  5 DP ports: +2 TMDS encoders
              +4 DPMST encoders
      *5 ports
      == 35 encoders

Which breaks things, since DRM has a hard coded limit of 32 encoders.
So, fix this by not creating MSTMs for any eDP connectors. This brings
us down to 31 encoders, although we can do better.

This fixes driver probing for nouveau on the ThinkPad P71.

drm/i915: Use NOEVICT for first pass on attemping to pin a GGTT mmap

The intention is that we first try to pin the current vma into the
mappable aperture only if it is already in use or it fits in the free

drm/i915: to make vgpu ppgtt notificaiton as atomic operation

vgpu ppgtt notification was split into 2 steps, the first step is to

drm/msm/dpu: fix "frame done" timeouts

Previously, dpu_crtc_frame_event_work() would try to aquire all the
modeset locks in order to check whether it can release bandwidth.  (If
we only have cmd-mode display, bandwidth can be released at frame-done
time.)

The problem with this is that it is also responsible for signalling
frame_done_comp, which dpu_crtc_commit_kickoff() waits on if there is
already a frame pending.  This is called in the msm_atomic_commit_tail()
path.. which means that for non-nonblock commits, at least some of the
modeset locks are already held.

Re-work this scheme to use a reference count to track our need to have
clocks enabled.  It is incremented for each atomic commit, and
decremented in the corresponding frame-done.  Additionally, any crtc
used in video mode hold an extra reference while they are enabled.  The
net effect is that we can determine in frame-done whether it is safe to
drop bandwidth without needing to aquire any modeset locks.

drm/msm: Use struct_size() helper

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct msm_gem_submit {
...
        struct {
...
        } bos[0];
};

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.

So, replace the following form:

sizeof(*submit) + ((u64)nr_bos * sizeof(submit->bos[0]))

with:

struct_size(submit, bos, nr_bos)

This code was detected with the help of Coccinelle.

drm/msm/hdmi: Convert to use GPIO descriptors

Normally we would fetch the GPIOs from the device with the

immediately, but since the code seems eager to actively

just fetch the GPIOs as-is and keep the code explicitly
driving them.

The old code would try legacy bindings (GPIOs without any
"-gpios" suffix) but this has been moved to the gpiolib
as a quirk by the previous patch.

before panfrost_perfcnt_init() is called which touches the h/w. The
autosuspend delay keeps things from breaking. There's no need explicitly
power off the GPU only to wake back up with pm_runtime_get_sync(). Just
delaying pm_runtime_enable to the end of probe is sufficient.

Lets move all the runtime PM calls into the probe() function so they are
all in one place and are done after all initialization.
