165 | strncpy(args->v0.name, device->name, sizeof(args->v0.name));
The reason of this warning is strncpy() does not guarantee that the
destination buffer will be NUL terminated. If the length of source string
is bigger than number we set by third input parameter, only a part of
characters is copied to the destination, and no NUL-terminated string is
automatically added. There are some potential risks.
So use snprintf() to replace strncpy().

When it comes to gamma or degamma luts, nouveau will actually skip the
calculation of certain LUTs depending on the head and plane states. For
instance, when the head is disabled we don't perform any error checking on
the gamma LUT, and likewise if no planes are present and enabled in our
atomic state we will skip error checking the degamma LUT. This is a bit of
a problem though, since the per-head gamma and degamma props in DRM can be
changed even while a head is disabled - a situation which can be triggered
by the igt testcase mentioned down below.
Originally I thought this was a bit silly and was tempted to just fix the
igt test to only set gamma/degamma with the head enabled. After a bit of
thinking though I realized we should fix this in nouveau. This is because
if a program decides to set an invalid LUT for a head before enabling the
head, such a property change would succeed while also making it impossible
to turn the head back on until the LUT is removed or corrected - something
that could be painful for a user to figure out.
So, fix this checking both degamma and gamma LUTs unconditionally during
atomic checks. We start by calling nv50_head_atomic_check_lut() regardless
of whether the head is active or not in nv50_head_atomic_check(). Then we
move the ilut error checking into nv50_head_atomic_check_lut() and add a
per-head hook for it, primarily because as a per-CRTC property DRM we want
the LUT to be error checked by the head any time it's included in an atomic
state. Of course though, actual programming of the degamma lut to hardware
is still handled in each plane's atomic check and commit.

Found this while trying to make some changes to the kms_cursor_crc test.
curs507a_acquire checks that the width and height of the cursor framebuffer
are equal (asyw->image.{w,h}). This isn't entirely correct though, as the
height of the cursor can be larger than the size of the cursor, as long as
the width is the same as the cursor size and there's no framebuffer offset.
Note that I'm not entirely sure why this wasn't previously breaking
kms_cursor_crc tests - they all set up cursors with the height being one
pixel larger than the actual size of the cursor. But this seems to fix
things, and the code before was definitely incorrect - so it's not really
worth looking into further imho.
Changes since v1:
* Don't use crtc_w everywhere for determining cursor layout, just use fb
size again
* Change check so that we only check that the w/h of the cursor plane is
the same, the width of the scanout surface is the same as the framebuffer
width, and that there's no offset being used for the cursor surface.

There have been reports of the WFI timing out on some boards, and a

and I believe the WFI might be needed with our FW prior to GM200.
However, we probably should not be touching PMU during init on GPUs
where we depend on NVIDIA FW, outside of limited circumstances, so
this should be a somewhat safer change that achieves the desired
result.

Something that didn't get noticed until I started running cursor tests:
we're accidentally disabling an option for CRC calculation that's enabled
by default: WidePipeCrc, which controls whether we use the full width of
the data in the display pipe in order calculate CRCs. Having this disabled
apparently causes frames with the cursor plane enabled to generate
different CRCs than frames without the cursor plane enabled, even if the
frames are pixel-equivalent.
So, let's make sure to enable this and fix a bunch of cursor related tests
in IGT.

Originally it was assumed based on Nvidia's open-gpu-docs and testing that
NVDisplay required that at least one wndw which belongs to a given head to
be used as the controlling channel
(NVC37D_HEAD_SET_CRC_CONTROL_CONTROLLING_CHANNEL) in order for CRC capture
to function. While this is the case on Volta, Turing actually adds the
ability to instead use the core channel as the controlling channel. For
Turing this is quite useful, as it means that we can always default to the
core channel as the controlling channel and we don't need to be concerned
about ensuring we have at least one wndw channel owned by a head with CRC
output enabled. While Volta lacks this ability, Volta conveniently also
lacks flexible wndw mapping - meaning that we can always rely on each head
having four wndw channels mapped to it regardless of the atomic state.
So, simply use the hard-coded wndw mappings we're guaranteed to have on
Volta as the controlling channel, and use the core channel as the
controlling channel for Turing+. As a result this also renders the plane
ownership logic in nv50_crc_atomic_check() unnessecary, which gives us one
less thing to implement when we get support for flexible wndw mapping. We
also can entirely drop the wndw parameter from our set_src callbacks, and
the atomic state.

The bridge functions are copied as-is, except:

- the mode_set has been moved to atomic_enable()
- debug prints are converted to dev_debg()
For now the bridge attach flags is 0, DRM_BRIDGE_ATTACH_NO_CONNECTOR

Since this bridge is tied to the connector, it acts like a passthrough,
so concerning the output & input bus formats, either pass the bus formats from the
previous bridge or return fallback data like done in the bridge function:
drm_atomic_bridge_chain_select_bus_fmts() & select_bus_fmt_recursive.
This permits avoiding skipping the negociation if the remaining bridge chain has
all the bits in place.
Without this bus fmt negociation breaks on drm/meson HDMI pipeline when attaching
dw-hdmi with DRM_BRIDGE_ATTACH_NO_CONNECTOR, because the last bridge of the
display-connector doesn't implement buf fmt callbacks and MEDIA_BUS_FMT_FIXED
is used leading to select an unsupported default bus format from dw-hdmi.

The current ELD handling takes the internal connector ELD buffer and
shares it to the I2S and AHB sub-driver.
But with DRM_BRIDGE_ATTACH_NO_CONNECTOR, the connector is created
elsewhere (or not), and an eventual connector is known only
if the bridge chain up to a connector is enabled.
The current dw-hdmi code gets the current connector from
atomic_enable() so use the already stored connector pointer and
replace the buffer pointer with a callback returning the current
connector ELD buffer.
Since a connector is not always available, either pass an empty
ELD to the alsa HDMI driver or don't call snd_pcm_hw_constraint_eld()
in AHB driver.

the mess just backmerge here.

The bspec's performance guide suggests programming specific values into
a few registers for optimal performance. Although these aren't
workarounds, it's easiest to handle them inside the GT workaround
functions (which will also ensure that the values set here are properly
melded with other bits in the same registers that _are_ set by
workarounds).

There are some additional workarounds specific to the compute engines
that we're holding back for now. Those will be added later, after
general compute engine support lands.

MIGRATE_PFN_LOCKED is used to indicate to migrate_vma_prepare() that a
source page was already locked during migrate_vma_collect(). If it
wasn't then the a second attempt is made to lock the page. However if
the first attempt failed it's unlikely a second attempt will succeed,
and the retry adds complexity. So clean this up by removing the retry
and MIGRATE_PFN_LOCKED flag.
Destination pages are also meant to have the MIGRATE_PFN_LOCKED flag
set, but nothing actually checks that.

Conventionally, panel is listed under the root of the device tree.
When userland asks for display mode, ps8640 bridge is responsible
for returning EDID when ps8640_bridge_get_edid() is called.
Now enable a new option of listing panel under "aux-bus" of ps8640
bridge node in the device tree. In this case, panel driver can retrieve
EDID by triggering AUX transactions, without ps8640_bridge_get_edid()
calls at all.
To prevent the "old" and "new" options from interfering with each
other's logic flow, disable DRM_BRIDGE_OP_EDID when the new option
is taken.

Fit ps8640 driver into runtime power management framework:
First, break _poweron() to 3 parts: (1) turn on power and wait for
ps8640's internal MCU to finish init (2) check panel HPD (which is
proxied by GPIO9) (3) the other configs. As runtime_resume() can be
called before panel is powered, we only add (1) to _resume() and leave
(2)(3) to _pre_enable(). We also add (2) to _aux_transfer() as we want
to ensure panel HPD is asserted before we start AUX CH transactions.
Second, the original driver has a mysterious delay of 50 ms between (2)
and (3). Since Parade's support can't explain what the delay is for,
and we don't see removing the delay break any boards at hand, remove
the delay to fit into this driver change.
In addition, rename "powered" to "pre_enabled" and don't check for it
in the pm_runtime calls. The pm_runtime calls are already refcounted
so there's no reason to check there. The other user of "powered",
_get_edid(), only cares if pre_enable() has already been called.
Lastly, change some existing DRM_...() logging to dev_...() along the
way, since DRM_...() seem to be deprecated in [1].

gv100_hdmi_ctrl() writes vendor_infoframe.subpack0_high to 0x6f0110, and
then overwrites it with 0. Just drop the overwrite with 0, that's clearly
a mistake.

Add constants for the maximum size of the shadow-plane surface
size. Useful for shadow planes with virtual screen sizes. The
current sizes are 4096 scanlines with 4096 pixels each. This
seems reasonable for current hardware, but can be increased as
necessary.
In simpledrm, set the maximum framebuffer size from the constants
for shadow planes. Implements support for virtual screen sizes and
