[Intel-gfx] [PATCH v8 1/8] drm/edid: split HDMI VSDB info and mode parsing

[Jani Nikula]

Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.

The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").

The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.

v2:
- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)

[Intel-gfx] [PATCH v8 2/8] drm/edid: refactor _drm_edid_connector_update() and rename

[Jani Nikula]

By moving update_display_info() out of _drm_edid_connector_update() we
make the function purely about adding modes. Rename accordingly.

[Intel-gfx] [PATCH v8 3/8] drm/edid: add separate drm_edid_connector_add_modes()

[Jani Nikula]

The original goal with drm_edid_connector_update() was to have a single
call for updating the connector and adding probed modes, in this order,
but that turned out to be problematic. Drivers that need to update the
connector in the .detect() callback would end up updating the probed
modes as well. Turns out the callback may be called so many times that
the probed mode list fills up without bounds, and this is amplified by
add_alternate_cea_modes() duplicating the CEA modes on every call,
actually running out of memory on some machines.

Kudos to Imre Deak <imre.deak@intel.com> for explaining this to me.

Go back to having separate drm_edid_connector_update() and
drm_edid_connector_add_modes() calls. The former may be called from
.detect(), .force(), or .get_modes(), but the latter only from
.get_modes().

Unlike drm_add_edid_modes(), have drm_edid_connector_add_modes() update
the probed modes from the EDID property instead of the passed in
EDID. This is mainly to enforce two things:

1) drm_edid_connector_update() must be called before
   drm_edid_connector_add_modes().

   Display info and quirks are needed for parsing the modes, and we
   don't want to call update_display_info() again to ensure the info is
   available, like drm_add_edid_modes() does.

2) The same EDID is used for both updating the connector and adding the
   probed modes.

Fortunately, the change is easy, because no driver has actually adopted
drm_edid_connector_update(). Not even i915, and that's mainly because of
the problem described above.

[Intel-gfx] [PATCH v8 5/8] drm/i915/edid: convert DP, HDMI and LVDS to drm_edid

[Jani Nikula]

Convert all the connectors that use cached connector edid and
detect_edid to drm_edid.

Since drm_get_edid() calls drm_connector_update_edid_property() while
drm_edid_read*() do not, we need to call drm_edid_connector_update()
separately, in part due to the EDID caching behaviour in HDMI and
DP. Especially DP depends on the details parsed from EDID. (The big
behavioural change conflating EDID reading with parsing and property
update was done in commit 5186421cbfe2 ("drm: Introduce epoch counter to
drm_connector"))

v6: Rebase on drm_edid_connector_add_modes()

v5: Fix potential uninitialized var use (kernel test robot <lkp@intel.com>)

v4: Call drm_edid_connector_update() after reading HDMI/DP EDID

v3: Don't leak vga switcheroo EDID in LVDS init (Ville)

v2: Don't leak opregion fallback EDID (Ville)

Maybe far fetched, but if the user does connector force disable via
debugfs, drm_helper_probe_single_connector_modes() will clear the EDID
property and display info. And after that, nobody's going to do the
connector update again unless we do it here.

Jani.

Right, DP/HDMI take care of that in .force(), we have no
.force() for LVDS atm. And I take the encoder types not handled
in this patch will keep using some older get_edid() thingy that
will do the update for them also from .get_modes()? Hmm, apart
from the encoders using intel_panel_get_modes() which I suppose
must already be busted...

I guess we should think about unifying the behaviour for all
the encoder types, including using detect_edid for everything...

Anyways, that's something for the future. For the time being

[Intel-gfx] [PATCH v8 6/8] drm/i915/bios: convert intel_bios_init_panel() to drm_edid

[Jani Nikula]

Try to use struct drm_edid where possible, even if having to fall back
to looking into struct edid down low via drm_edid_raw().

[Intel-gfx] [PATCH v8 8/8] drm/i915/panel: move panel fixed EDID to struct intel_panel

[Jani Nikula]

It's a bit confusing to have two cached EDIDs in struct intel_connector
with slightly different purposes. Make the distinction a bit clearer by
moving the EDID cached for eDP and LVDS panels at connector init time to
struct intel_panel, and name it fixed_edid. That's what it is, a fixed
EDID for the panels.
