Backmerge tag 'v5.17-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into drm-next
Daniel asked for this for some intel deps, so let's do it now.
Signed-off-by: Dave Airlie <airlied@redhat.com>
Currently we can get a warning on systems with eDP backlights like so:
nv_backlight: invalid backlight type
WARNING: CPU: 4 PID: 454 at drivers/video/backlight/backlight.c:420
backlight_device_register+0x226/0x250
This happens as a result of us not filling out props.type for the eDP
backlight, even though we do it for all other backlight types.
Since nothing in our driver uses anything but BACKLIGHT_RAW, let's take the
props\.type assignments out of the codepaths for individual backlight types
and just set it unconditionally to prevent this from happening again.

It seems that some laptops will report having both an eDP and LVDS
connector, even though only the LVDS connector is actually hooked up. This
can lead to issues with backlight registration if the eDP connector ends up
getting registered before the LVDS connector, as the backlight device will
then be registered to the eDP connector instead of the LVDS connector.
So, fix this by only registering the backlight on connectors that are
reported as being connected.

Bounds checking when parsing init scripts embedded in the BIOS reject
access to the last byte. This causes driver initialization to fail on
Apple eMac's with GeForce 2 MX GPUs, leaving the system with no working
console.
This is probably only seen on OpenFirmware machines like PowerPC Macs
because the BIOS image provided by OF is only the used parts of the ROM,
not a power-of-two blocks read from PCI directly so PCs always have
empty bytes at the end that are never accessed.

If only linear modifier is advertised, since there are many drivers that
only linear supported, the DRM core should handle this rather than
open-coding in every driver. However, there are legacy drivers such as
radeon that do not support modifiers but infer the actual layout of the
underlying buffer. Therefore, a new flag fb_modifiers_not_supported is
introduced for these legacy drivers, and allow_fb_modifiers is replaced
with this new flag.
v3:
- change the order as follows:
1. add fb_modifiers_not_supported flag
2. add default modifiers
3. remove allow_fb_modifiers flag
- add a conditional disable in amdgpu_dm_plane_init()

Move DisplayPort functions into a separate module to reduce the size
of the KMS helpers. Select DRM_DP_HELPER for all users of the code. To
avoid naming conflicts, rename drm_dp_helper.c to drm_dp.c
This change can help to reduce the size of the kernel binary. Some
numbers from a x86-64 test build:
Before:
drm_kms_helper.ko: 447480 bytes
After:
drm_dp_helper.ko: 216632 bytes
drm_kms_helper.ko: 239424 bytes
For early-boot graphics, generic DRM drivers, such as simpledrm,
require DRM KMS helpers to be built into the kernel. Generic helper
functions for DisplayPort take up a significant portion of DRM KMS
helper library. These functions are not used by generic drivers and
can be loaded as a module.
v3:
* fix include statement in DRM selftests
v2:

eDP 1.4 adds a table of link rates supported by the sink to DPCD, as
well as a LINK_RATE_SET register to select between the entries in it.
If present, we will use this data to generate our internal link rate
table rather than using the standard list based on MAX_LINK_RATE.
Some recent laptops report MAX_LINK_RATE=0, and require this support.

Merge v5.16-rc5 into drm-next
Thomas Zimmermann requested a fixes backmerge, specifically also for
96c5f82ef0a1 ("drm/vc4: fix error code in vc4_create_object()")
Just a bunch of adjacent changes conflicts, even the big pile of them
in vc4.

The "nomodeset" kernel cmdline parameter is handled by the vgacon driver
but the exported vgacon_text_force() symbol is only used by DRM drivers.
It makes much more sense for the parameter logic to be in the subsystem
of the drivers that are making use of it.
Let's move the vgacon_text_force() function and related logic to the DRM
subsystem. While doing that, rename it to drm_firmware_drivers_only() and
make it return true if "nomodeset" was used and false otherwise. This is
a better description of the condition that the drivers are testing for.

The nouveau driver outputs full range RGB, but the AVI InfoFrame just says
'Default' instead of 'Full'.
Call drm_hdmi_avi_infoframe_quant_range to fill in the quantization field
of the AVI InfoFrame correctly. Now displays that advertise RGB Selectable
Quantization Range in their EDID will understand that full range is
transmitted by the HDMI output. This is consistent to how the Nvidia's

Following warning is found when using W=1 to build kernel:
In function ‘nvkm_udevice_info’,
inlined from ‘nvkm_udevice_mthd’ at drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:195:10:
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:164:2: warning: ‘strncpy’ specified bound 16 equals destination size [-Wstringop-truncation]
164 | strncpy(args->v0.chip, device->chip->name, sizeof(args->v0.chip));
drivers/gpu/drm/nouveau/nvkm/engine/device/user.c:165:2: warning: ‘strncpy’ specified bound 64 equals destination size [-Wstringop-truncation]
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().

The struct is giant, and triggers an order-7 allocation (512K). There is
no reason for this to be kmalloc-type memory, so switch to vmalloc. This
should help loading nouveau on low-memory and/or long-running systems.

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.

Since this is used in the atomic check, we should use the right debug macro
for it.

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
patch was proposed to just remove it. This stuff is rather fragile,
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.
