[Intel-gfx] [PATCH v6 00/12] drm/edid, drm/i915: further drm_edid work, finally switch i915 over

[Jani Nikula]

The drm_edid handling still needed some plumbing in drm_edid.c before we
could convert i915 over to use it. Specifically
drm_edid_connector_update() needed to be split to two, with separate
drm_edid_connector_add_modes(). This is better explained in patch 7
commit message.

With that in patches 1-8 along with some refactorings, we can finally
switch i915 over to use drm_edid. And with that, i915 starts supporting
the HF-EEODB extension.

I've dropped Ville's earlier R-b from some of the patches because
they've changed so much over the rebases and changes.


BR,
Jani.

[Intel-gfx] [PATCH v6 01/12] drm/edid: store quirks in display info

[Jani Nikula]

Although the quirks are internal to EDID parsing, it'll be helpful to
store them in display info to avoid having to pass them around.

This will also help separate adding probed modes (which needs the
quirks) from updating display info.

[Jani Nikula]

Now that quirks are stored in display info, we can just look them up
using the connector instead of having to pass them around.

[Intel-gfx] [PATCH v6 06/12] 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.

I don't think that's quite true. The 4:2:0 stuff still updates
various display_info things from the mode parsing functions.

So what's going to happen with the 4:2:0 stuff? Are we just clobbering
it if/when someone calls the update_display_info() stuff w/o calling 
add_modes()?

Don't do that then?

*sigh*

I don't know.

It's pretty much the same thing as only calling update_display_info(),
before adding modes, and looking at the relevant info fields *before*
the add modes call. That's probably already happening.

I really wanted to put this all together into one call so nobody could
do that silly stuff. But then for various reasons drivers want to not
only read the EDID but also parse it in ->detect, and ->detect gets
called a lot.

We can't keep adding modes to probed modes in ->detect all the time
without pruning them. I thought about trying to avoid adding duplicated
modes in probed modes list, but it looks like another rabbit hole with
no end in sight. Don't really want to go that route.

If we want to make this fool proof, one way to fix this would be to do
all the info changes in step 1, even the ones that are currently added
via add modes. Iterate through everything, but only do the info
changes. And in step 2 only add the modes to probed modes list.

In any case, the current state of affairs is bonkers already. There's
supposed to be 1) reading the EDID, 2) updating the info, and 3) adding
the modes. But both drm_get_edid() *and* drm_add_edid_modes() do the
display info and property update part too. We've just been adding calls
here and there to patch things up. Nobody cares. Just add more calls
updating stuff, and hope it'll be fine. That's gotta stop.

[Intel-gfx] [PATCH v6 07/12] 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 v6 08/12] drm/edid: remove redundant _drm_connector_update_edid_property()

[Jani Nikula]

Realize that drm_edid_connector_update() and
_drm_connector_update_edid_property() are now the same thing. Drop the
latter.

[Intel-gfx] [PATCH v6 09/12] 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)

[Intel-gfx] [PATCH v6 10/12] 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().

v2: Rebase

[Intel-gfx] [PATCH v6 12/12] 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.
