Replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
---------------------------------------------------------------

Once EDID is parsed, the monitor HDMI support information is available through
drm_display_info.is_hdmi. Many drivers still call drm_detect_hdmi_monitor() to
retrieve the same information, which is less efficient.

Audit each individual driver calling drm_detect_hdmi_monitor() and switch to
drm_display_info.is_hdmi if applicable.
=====

I did it in two steps:
- check that drm_display_info has a correct value.
- in that case, replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

Almost all occurrences of drm_detect_hdmi_monitor() could be changed. Some
small inconsistencies have been solved.

[PATCH 01/15] gpu/drm: make drm_add_edid_modes() consistent when updating connector->display_info

[Claudio Suarez]

According to the documentation, drm_add_edid_modes
"... Also fills out the &drm_display_info structure and ELD in @connector
with any information which can be derived from the edid."

drm_add_edid_modes accepts a struct edid *edid parameter which may have a
value or may be null. When it is not null, connector->display_info and
connector->eld are updated according to the edid. When edid=NULL, only
connector->eld is reset. Reset connector->display_info to be consistent
and accurate.

[PATCH 02/15] drm/amdgpu: use drm_* functions instead of duplicated code in amdgpu driver

[Claudio Suarez]

a) Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. The amdgpu driver still calls
drm_detect_hdmi_monitor() to retrieve the same information, which
is less efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

b) drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always.  Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated. This allows a)
to work properly.

c) Use drm_edid_get_monitor_name() instead of duplicating the code that
parses the EDID in dm_helpers_parse_edid_caps()

Also, remove the unused "struct dc_context *ctx" parameter in
dm_helpers_parse_edid_caps()

[Intel-gfx] [PATCH 02/15] drm/amdgpu: use drm_* functions instead of duplicated code in amdgpu driver

[Claudio Suarez]

a) Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. The amdgpu driver still calls
drm_detect_hdmi_monitor() to retrieve the same information, which
is less efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

b) drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always.  Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated. This allows a)
to work properly.

c) Use drm_edid_get_monitor_name() instead of duplicating the code that
parses the EDID in dm_helpers_parse_edid_caps()

Also, remove the unused "struct dc_context *ctx" parameter in
dm_helpers_parse_edid_caps()

[Nouveau] [PATCH 02/15] drm/amdgpu: use drm_* functions instead of duplicated code in amdgpu driver

[Claudio Suarez]

a) Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. The amdgpu driver still calls
drm_detect_hdmi_monitor() to retrieve the same information, which
is less efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

b) drm_display_info is updated by drm_get_edid() or
drm_connector_update_edid_property(). In the amdgpu driver it is almost
always updated when the edid is read in amdgpu_connector_get_edid(),
but not always.  Change amdgpu_connector_get_edid() and
amdgpu_connector_free_edid() to keep drm_display_info updated. This allows a)
to work properly.

c) Use drm_edid_get_monitor_name() instead of duplicating the code that
parses the EDID in dm_helpers_parse_edid_caps()

Also, remove the unused "struct dc_context *ctx" parameter in
dm_helpers_parse_edid_caps()

[PATCH 03/15] drm/vc4: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Use this value instead of calling
drm_detect_hdmi_monitor() to avoid a second parse.

This is a TODO task in Documentation/gpu/todo.rst

[PATCH 04/15] drm/radeon: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information is less
efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

Also, correct an inacurracy or bug in
radeon_connector_get_edid()/radeon_connector_free_edid(). Two variables
have EDID data:
- struct radeon_connector.edid
- struct drm_connector.edid_blob_ptr
The second is updated by calling drm_connector_update_edid_property() or
drm_get_edid() - which internally calls drm_connector_update_edid_property().
drm_display_info.is_hdmi is updated when this function is called.
radeon_connector_get_edid() calls drm_get_edid() to update
drm_connector.edid_blob_ptr/drm_display_info only in some cases. Change it
to be always up to date, so drm_display_info is always correct.
As counterpart, reset these values in radeon_connector_free_edid().

This second change is necessary for the previous one to work properly.

- struct drm_connector.edid_blob_ptr
The second is updated by calling drm_connector_update_edid_property() or
drm_get_edid() - which internally calls drm_connector_update_edid_property().
drm_display_info.is_hdmi is updated when this function is called.
radeon_connector_get_edid() calls drm_get_edid() to update
drm_connector.edid_blob_ptr/drm_display_info only in some cases. Change it
to be always up to date, so drm_display_info is always correct.
As counterpart, reset these values in radeon_connector_free_edid().

This second change is necessary for the previous one to work properly.

[Nouveau] [PATCH 04/15] drm/radeon: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information is less
efficient. Change to drm_display_info.is_hdmi

This is a TODO task in Documentation/gpu/todo.rst

Also, correct an inacurracy or bug in
radeon_connector_get_edid()/radeon_connector_free_edid(). Two variables
have EDID data:
- struct radeon_connector.edid
- struct drm_connector.edid_blob_ptr
The second is updated by calling drm_connector_update_edid_property() or
drm_get_edid() - which internally calls drm_connector_update_edid_property().
drm_display_info.is_hdmi is updated when this function is called.
radeon_connector_get_edid() calls drm_get_edid() to update
drm_connector.edid_blob_ptr/drm_display_info only in some cases. Change it
to be always up to date, so drm_display_info is always correct.
As counterpart, reset these values in radeon_connector_free_edid().

This second change is necessary for the previous one to work properly.

[Nouveau] [PATCH 05/15] drm/tegra: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi

[PATCH 10/15] drm/sti: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi

[Nouveau] [PATCH 13/15] drm/bridge: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi where possible

[Intel-gfx] [PATCH 15/15] drm/i915: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Claudio Suarez]

Once EDID is parsed, the monitor HDMI support information is available
through drm_display_info.is_hdmi. Retriving the same information with
drm_detect_hdmi_monitor() is less efficient. Change to
drm_display_info.is_hdmi where possible.

This is a TODO task in Documentation/gpu/todo.rst

Looks easier if you pull both of those out from these branches and
just call them unconditionally at the start.

Hmm. Have we parse the EDID by this point actually? I don't think that
was the case in the past but maybe it changed at some point.

Not sure it's actually helpful for i915. We end up having to root around
in the display_info in a lot of places anyway. So a helper for single
boolean seems a bit out of place perhaps.

Thanks for this work.

The fact that you listed three separate changes in this commit
is a clear indication that this patch should be three separate
patches instead. Separating the functional bits from the straight
refactor will help with bisection if this leads to a regression.

All changes look reasonable to me, though. With this patch split
into three patches in the sequence (b), (c), then (a) this is

Thanks for this work.

The fact that you listed three separate changes in this commit
is a clear indication that this patch should be three separate
patches instead. Separating the functional bits from the straight
refactor will help with bisection if this leads to a regression.

All changes look reasonable to me, though. With this patch split
into three patches in the sequence (b), (c), then (a) this is

Thanks for this work.

The fact that you listed three separate changes in this commit
is a clear indication that this patch should be three separate
patches instead. Separating the functional bits from the straight
refactor will help with bisection if this leads to a regression.

All changes look reasonable to me, though. With this patch split
into three patches in the sequence (b), (c), then (a) this is

*shrug*

Maybe it's just my frustration at the lack of interfaces and poking
around in the depths of nested structs and pointer chasing that's coming
through. You just need to change so many things if you want to later
refactor where "is hdmi" comes from and is stored.

Anyway, if a helper is being added like in this series, I think it
should be one helper in drm, not redundant copies in multiple
drivers. Or we should not have the helper(s) at all. One or the other,
not the worst of both worlds.

Yes, I think so. The complete code is:

----
        edid = drm_get_edid(connector, i2c);

        if (!edid && !intel_gmbus_is_forced_bit(i2c)) {
                drm_dbg_kms(&dev_priv->drm,
                            "HDMI GMBUS EDID read failed, retry using GPIO bit-banging\n");
                intel_gmbus_force_bit(i2c, true);
                edid = drm_get_edid(connector, i2c);
                intel_gmbus_force_bit(i2c, false);
        }

        intel_hdmi_dp_dual_mode_detect(connector, edid != NULL);

        intel_display_power_put(dev_priv, POWER_DOMAIN_GMBUS, wakeref);

        to_intel_connector(connector)->detect_edid = edid;
        if (edid && edid->input & DRM_EDID_INPUT_DIGITAL) {
                intel_hdmi->has_audio = drm_detect_monitor_audio(edid);
                intel_hdmi->has_hdmi_sink = intel_connector_is_hdmi_monitor(connector);
----
The edid value comes from drm_get_edid(), first or second.
drm_get_edid() internally calls drm_connector_update_edid_property()
drm_connector_update_edid_property() calls drm_add_display_info() and parses the edid.
So, the edid is parsed.
I checked this and I read the docs many times because at the first time I felt something
was wrong. But that is the sequence of calls.

Yes. But in this case the edid comes from intel_dp_get_edid().
In intel_dp_get_edid(), there is a if. One of the branches calls drm_get_edid(),
so no problem here. But the other branch gets the edid from drm_edid_duplicate().
I haven't seen any guarantee that display_info is updated in this case.

I didn't change this file for that reason.

Yes, I think so. The complete code is:

----
        edid = drm_get_edid(connector, i2c);

        if (!edid && !intel_gmbus_is_forced_bit(i2c)) {
                drm_dbg_kms(&dev_priv->drm,
                            "HDMI GMBUS EDID read failed, retry using GPIO bit-banging\n");
                intel_gmbus_force_bit(i2c, true);
                edid = drm_get_edid(connector, i2c);
                intel_gmbus_force_bit(i2c, false);
        }

        intel_hdmi_dp_dual_mode_detect(connector, edid != NULL);

        intel_display_power_put(dev_priv, POWER_DOMAIN_GMBUS, wakeref);

        to_intel_connector(connector)->detect_edid = edid;
        if (edid && edid->input & DRM_EDID_INPUT_DIGITAL) {
                intel_hdmi->has_audio = drm_detect_monitor_audio(edid);
                intel_hdmi->has_hdmi_sink = intel_connector_is_hdmi_monitor(connector);
----
The edid value comes from drm_get_edid(), first or second.
drm_get_edid() internally calls drm_connector_update_edid_property()
drm_connector_update_edid_property() calls drm_add_display_info() and parses the edid.

Thank you all for your comments :)
The big work here was to figure out which drm_detect_hdmi_monitor() can be
replaced. Changing a helper isn't a problem.
I'll send a new patch in a few hours.

After looking at the full code, I am not sure. This is the code:
==================
int drm_add_edid_modes(struct drm_connector *connector, struct edid *edid)
{
        int num_modes = 0;
        u32 quirks;

        if (edid == NULL) {
                clear_eld(connector);
                drm_reset_display_info(connector); <--- added by me
                return 0;
        }
        if (!drm_edid_is_valid(edid)) {
                clear_eld(connector);
                drm_reset_display_info(connector); <--- added by me
                drm_warn(connector->dev, "%s: EDID invalid.\n",
                         connector->name);
                return 0;
        }

        drm_edid_to_eld(connector, edid);

        quirks = drm_add_display_info(connector, edid);
	etc...
=================

If we move those out of these branches and edid != NULL, we are executing an
unnecessary clear_eld(connector) and an unnecessary drm_reset_display_info(connector)
because the fields will be set in the next drm_edid_to_eld(connector, edid) and
drm_add_display_info(connector, edid)

Do we want this ?

        u32 quirks;

        if (edid == NULL) {
                clear_eld(connector);
                drm_reset_display_info(connector); <--- added by me
                return 0;
        }
        if (!drm_edid_is_valid(edid)) {
                clear_eld(connector);
                drm_reset_display_info(connector); <--- added by me
                drm_warn(connector->dev, "%s: EDID invalid.\n",
                         connector->name);
                return 0;
        }

        drm_edid_to_eld(connector, edid);

        quirks = drm_add_display_info(connector, edid);
	etc...
=================

If we move those out of these branches and edid != NULL, we are executing an
unnecessary clear_eld(connector) and an unnecessary drm_reset_display_info(connector)
because the fields will be set in the next drm_edid_to_eld(connector, edid) and
drm_add_display_info(connector, edid)

Do we want this ?

Seems fine by me. And maybe we could nuke the second
drm_reset_display_info() from deeper inside drm_add_display_info()?
Not sure if drm_add_display_info() still has to be able to operate
standalone or not.

Hmm. Another option is to just move all these NULL/invalid edid
checks into drm_edid_to_eld() and drm_add_display_info().

I was thinking about this. We can use a boolean variable:
===============
        bool edid_is_invalid;

	edid_is_invalid = !drm_edid_is_valid(edid);

        if (edid == NULL || edid_is_invalid) {
                clear_eld(connector);
                drm_reset_display_info(connector);
                if (edid_is_invalid)
                         drm_warn(connector->dev, "%s: EDID invalid.\n",
                                  connector->name);
                return 0;
        }

        drm_edid_to_eld(connector, edid);
...
===============
Internally, drm_edid_is_valid() handles NULL pointers properly.
It is a quite elegant solution with a small change in the original
design, and it improves this part in the way you pointed out.
