Wayne Lin d2b434730f drm/edid: Add aspect ratios to HDMI 4K modes
[Why]
HDMI 2.0 adds aspect ratio attribute to distinguish different
4k modes. According to Appendix E of HDMI 2.0 spec, source should
use VSIF to indicate video mode only when the mode is one defined
in HDMI 1.4b 4K modes. Otherwise, use AVI infoframes to convey VIC.

Current code doesn't take aspect ratio into consideration while
constructing avi infoframe. Should modify that.

[How]
Inherit Ville Syrjälä's work
"drm/edid: Prep for HDMI VIC aspect ratio" at
https://patchwork.kernel.org/patch/11174639/

Add picture_aspect_ratio attributes to edid_4k_modes[] and

consideration.

Ville Syrjälä 949561eb85 drm/edid: Fix HDMI VIC handling
Extract drm_mode_hdmi_vic() to correctly calculate the final HDMI
VIC for us. Currently this is being done a bit differently between
the AVI and HDMI infoframes. Let's get both to agree on this.

We need to allow the case where a mode is both 3D and has a HDMI
VIC. Currently we'll just refuse to generate the HDMI infoframe when
we really should be setting HDMI VIC to 0 and instead enabling 3D
stereo signalling.

If the sink doesn't even support the HDMI infoframe we should
not be picking the HDMI VIC in favor of the CEA VIC, because then
we'll end up not sending either VIC in the end.

Lee Shawn C bfef04adb3 drm/edid: Select DMT timing if EDID's display feature not support GTF
Refer to EDID 1.3 spec, display FEATURE (byte 18h) bit #0 said
"If this bit is set to 1, the display supports timings based on the
GTF standard using default GTF parameter values".

And EDID 1.4 spec shows "If bit 0 is set to 0, then the display
is noncontinuous frequency (multi-mode) and is only specified to accept
the video timing formats that are listed in BASE EDID and certain
EXTENSION Blocks.

When display feature did not support CVT or GFT2 and monitor's EDID version
greater than or equal to "1.2". DRM driver would select GTF as default
for standard timing calculation. It may generated some video timing
that can't display properly by external monitor.

For example. When driver retrieved "0xD1 0xFC" (FHD, 120Hz) and
"0xD1 0xE8" (FHD, 100Hz) from "Standard Timings". GTF formula
would generate video timing like below. It already over monitor's
spec to cause black screen issue.
"1920x1080" 120 368881 1920 2072 2288 2656 1080 1081 1084 1157 0x0 0x6

v2: Just confirm GTF flag and omit the revision check.

Daniel Vetter c7581a414d drm: Use EOPNOTSUPP, not ENOTSUPP
- it's what we recommend in our docs:

https://dri.freedesktop.org/docs/drm/gpu/drm-uapi.html#recommended-ioctl-return-values

- it's the overwhelmingly used error code for "operation not
  supported", at least in drm core (slightly less so in drivers):

$ git grep EOPNOTSUPP -- drivers/gpu/drm/*c | wc -l
83
$ git grep ENOTSUPP -- drivers/gpu/drm/*c | wc -l
5

- include/linux/errno.h makes it fairly clear that these are for nfsv3
  (plus they also have error codes above 512, which is the block with
  some special behaviour ...)

/* Defined for the NFSv3 protocol */

If the above isn't reflecting current practice, then I guess we should
at least update the docs.

Noralf commented:

Ben Hutchings made this comment[1] in a thread about use of ENOTSUPP in
drivers:

  glibc's strerror() returns these strings for ENOTSUPP and EOPNOTSUPP
  respectively:

  "Unknown error 524"
  "Operation not supported"

So at least for errors returned to userspace EOPNOTSUPP makes sense.

José asked:

> Hopefully this will not break any userspace

None of the functions in drm_edid.c affected by this reach userspace,
it's all driver internal.

Same for the mipi function, that error code should be handled by
drivers. Drivers are supposed to remap "the hw is on fire" to EIO when
reporting up to userspace, but I think if a driver sees this it would
be a driver bug.
v2: Augment commit message with comments from Noralf and José

Jani Nikula 48eaeb7664 drm: add fallback override/firmware EDID modes workaround
We've moved the override and firmware EDID (simply "override EDID" from
now on) handling to the low level drm_do_get_edid() function in order to
transparently use the override throughout the stack. The idea is that
you get the override EDID via the ->get_modes() hook.

Unfortunately, there are scenarios where the DDC probe in drm_get_edid()
called via ->get_modes() fails, although the preceding ->detect()
succeeds.

In the case reported by Paul Wise, the ->detect() hook,
intel_crt_detect(), relies on hotplug detect, bypassing the DDC. In the
case reported by Ilpo Järvinen, there is no ->detect() hook, which is
interpreted as connected. The subsequent DDC probe reached via
->get_modes() fails, and we don't even look at the override EDID,
resulting in no modes being added.

Because drm_get_edid() is used via ->detect() all over the place, we
can't trivially remove the DDC probe, as it leads to override EDID
effectively meaning connector forcing. The goal is that connector
forcing and override EDID remain orthogonal.

Generally, the underlying problem here is the conflation of ->detect()
and ->get_modes() via drm_get_edid(). The former should just detect, and
the latter should just get the modes, typically via reading the EDID. As
long as drm_get_edid() is used in ->detect(), it needs to retain the DDC
probe. Or such users need to have a separate DDC probe step first.

The EDID caching between ->detect() and ->get_modes() done by some
drivers is a further complication that prevents us from making
drm_do_get_edid() adapt to the two cases.

Work around the regression by falling back to a separate attempt at
getting the override EDID at drm_helper_probe_single_connector_modes()
level. With a working DDC and override EDID, it'll never be called; the
override EDID will come via ->get_modes(). There will still be a failing
DDC probe attempt in the cases that require the fallback.

v2:
- Call drm_connector_update_edid_property (Paul)
- Update commit message about EDID caching (Daniel)

Ville Syrjälä 3bde449f0b drm/edid: Ignore "DFP 1.x" bit for EDID 1.2 and earlier
From VESA EDID implementation guide v1.0:
"For EDID version 1 revision 2 or earlier data structures when offset 14h
 bit 7 is set to one, the value of bits 6-0 are undefined, and therefore
 cannot be interpreted to mean anything."

And since EDID 1.4 redefines that bit let's consult it only for
EDID 1.3.

Ville Syrjälä 9d5549d8a8 drm/edid: Remove defunct EDID_QUIRK_FIRST_DETAILED_PREFERRED
Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything.
Its counterpart in f86EdidModes.c is properly hooked up but somehow
that functionality was lost when it was copied into the kernel.

The concensus seems to be that this quirk is a bit misguided
anyway so let's nuke the leftovers.

Kees Cook 6da2ec5605 treewide: kmalloc() -> kmalloc_array()
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This
patch replaces cases of:

        kmalloc(a * b, gfp)

with:
        kmalloc_array(a * b, gfp)

as well as handling cases of:

        kmalloc(a * b * c, gfp)

with:

        kmalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kmalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kmalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The tools/ directory was manually excluded, since it has its own
implementation of kmalloc().

The Coccinelle script used for this was:

Stanislav Lisovskiy 50525c332b drm: content-type property for HDMI connector
Added content_type property to drm_connector_state
in order to properly handle external HDMI TV content-type setting.

v2:
 * Moved helper function which attaches content type property
   to the drm core, as was suggested.
   Removed redundant connector state initialization.

v3:
 * Removed caps in drm_content_type_enum_list.
   After some discussion it turned out that HDMI Spec 1.4
   was wrongly assuming that IT Content(itc) bit doesn't affect
   Content type states, however itc bit needs to be manupulated
   as well. In order to not expose additional property for itc,
   for sake of simplicity it was decided to bind those together
   in same "content type" property.

v4:
 * Added it_content checking in intel_digital_connector_atomic_check.
   Fixed documentation for new content type enum.

v5:
 * Moved patch revision's description to commit messages.

v6:
 * Minor naming fix for the content type enumeration string.

v7:
 * Fix parameter name for documentation and parameter alignment
   in order not to get warning. Added Content Type description to
   new HDMI connector properties section.

v8:
 * Thrown away unneeded numbers from HDMI content-type property
   description. Switch to strings desription instead of plain
   definitions.

v9:
 * Moved away hdmi specific content-type enum from
   drm_connector_state. Content type property should probably not
   be bound to any specific connector interface in
   drm_connector_state.
   Same probably should be done to hdmi_picture_aspect_ration enum
   which is also contained in drm_connector_state. Added special
   helper function to get derive hdmi specific relevant infoframe
   fields.

v10:
 * Added usage description to HDMI properties kernel doc.

v11:
 * Created centralized function for filling HDMI AVI infoframe, based
   on correspondent DRM property value.
