[PATCH 1/2] drm/edid: abstract override/firmware EDID retrieval

[Jani Nikula]

Abstract the debugfs override and the firmware EDID retrieval
function. We'll be needing it in the follow-up. No functional changes.

[PATCH 2/2] drm: add fallback override/firmware EDID modes workaround

[Jani Nikula]

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.

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.

I think we should also highlight here that EDID caching between ->detect
and ->get_modes is a further complicating concern, which is why making
drm_do_get_edid magically dtrt between ->detect and ->get_modes doesn't
work either.

Aside from that nit I think this covers our lengthy discussion completely.

As discussed on irc, we need tested-by here from the reporters since
there's way too many losing and frustrangingly few winning moves here.

With all that, on the series:

I've tested these two patches on top of Linux v5.2-rc3 and the EDID
override works correctly on an Intel Ironlake GPU with a monitor that
lost its EDID a while ago.

I'll test that it also works with an nVidia GPU & noveau drivers later
today once that system is available.

While testing I noticed a couple of things:

While everything the GUI is the correct resolution, GNOME is unable to
identify the monitor vendor or model. This is a regression from the
previous edid override functionality. It looks like this is because the
edid file in /sys is not populated with the EDID override data.

I got a crash due to null pointer dereference at one point, I'll try to
track down when this happens.

Right, I've added a call to drm_connector_update_edid_property() in v2
to address this issue.

Can't think of why this would happen; the backtrace might offer clues.

Same results as with the Intel GPU:

[PATCH v2] drm: add fallback override/firmware EDID modes workaround

[Jani Nikula]

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)
