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

[Freedreno] [PATCH 00/15] replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
Copy&paste from the TODO document Documentation/gpu/todo.rst === 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.

[Freedreno] [PATCH 04/15] drm/radeon: 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. 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.

[Freedreno] [PATCH 02/15] drm/amdgpu: use drm_* functions instead of duplicated code in amdgpu driver
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() Signed-off-by: Claudio Suarez --- .../gpu/drm/amd/amdgpu/amdgpu_connectors.c| 23 +++ .../gpu/drm/amd/amdgpu/amdgpu_connectors.h| 2 + drivers/gpu/drm/amd/amdgpu/amdgpu_display.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_encoders.c | 4 +- .../gpu/drm/amd/amdgpu/atombios_encoders.c| 6 +-- .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 3 +- .../amd/display/amdgpu_dm/amdgpu_dm_helpers.c | 39 ++- drivers/gpu/drm/amd/display/dc/core/dc.c | 2 +- drivers/gpu/drm/amd/display/dc/dm_helpers.h | 2 +- 9 files changed, 39 insertions(+), 44 deletions(-) diff --git a/drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c b/drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c index b9c11c2b2885..7b41a1120b70 100644 --- a/drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c +++ b/drivers/gpu/drm/amd/amdgpu/amdgpu_connectors.c @@ -25,6 +25,7 @@ */ #include +#include #include #include #include @@ -108,7 +109,7 @@ int amdgpu_connector_get_monitor_bpc(struct drm_connector *connector) case DRM_MODE_CONNECTOR_DVII: case DRM_MODE_CONNECTOR_HDMIB: if (amdgpu_connector->use_digital) { - if (drm_detect_hdmi_monitor(amdgpu_connector_edid(connector))) { + if (amdgpu_connector_is_hdmi_monitor(connector)) { if (connector->display_info.bpc) bpc = connector->display_info.bpc; } @@ -116,7 +117,7 @@ int amdgpu_connector_get_monitor_bpc(struct drm_connector *connector) break; case DRM_MODE_CONNECTOR_DVID: case DRM_MODE_CONNECTOR_HDMIA: - if (drm_detect_hdmi_monitor(amdgpu_connector_edid(connector))) { + if (amdgpu_connector_is_hdmi_monitor(connector)) { if (connector->display_info.bpc) bpc = connector->display_info.bpc; } @@ -125,7 +126,7 @@ int amdgpu_connector_get_monitor_bpc(struct drm_connector *connector) dig_connector = amdgpu_connector->con_priv; if ((dig_connector->dp_sink_type == CONNECTOR_OBJECT_ID_DISPLAYPORT) || (dig_connector->dp_sink_type == CONNECTOR_OBJECT_ID_eDP) || - drm_detect_hdmi_monitor(amdgpu_connector_edid(connector))) { + (amdgpu_connector_is_hdmi_monitor(connector))) { if (connector->display_info.bpc) bpc = connector->display_info.bpc; } @@ -149,7 +150,7 @@ int amdgpu_connector_get_monitor_bpc(struct drm_connector *connector) break; } - if (drm_detect_hdmi_monitor(amdgpu_connector_edid(connector))) { + if (amdgpu_connector_is_hdmi_monitor(connector)) { /* * Pre DCE-8 hw can't handle > 12 bpc, and more than 12 bpc doesn't make * much sense without support for > 12 bpc framebuffers.

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. > > > > > conn

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.

[Freedreno] [PATCH v2 02/13] drm/vc4: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi

[Freedreno] [PATCH v2 01/13] gpu/drm: make drm_add_edid_modes() consistent when updating connector->display_info
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.

[Freedreno] [PATCH v2 00/13] replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
Changelog: v2: - no helper function - A separate patch is made for amdgpu - zte patch is removed because that driver no longer exists [Why] Copy&paste from Documentation/gpu/todo.rst === 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. = [How] 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.

[Freedreno] [PATCH v2 03/13] drm/radeon: 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. 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.

Re: [Freedreno] [PATCH v3 01/13] gpu/drm: make drm_add_edid_modes() consistent when updating connector->display_info
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. Since drm_edid_is_valid() considers NULL as an invalid EDID, simplify the code to avoid duplicating code in the case of NULL/error.

Re: [Freedreno] [PATCH v3 13/13] drm/i915: replace drm_detect_hdmi_monitor() with drm_display_info.is_hdmi
drm_get_edid() internally calls to drm_connector_update_edid_property() and then drm_add_display_info(), which parses the EDID. This happens in the function intel_hdmi_set_edid() and intel_sdvo_tmds_sink_detect() (via intel_sdvo_get_edid()).

Well, I studied it carefully and, yes, all call chains that can lead to drm_display_info.is_hdmi / drm_detect_hdmi_monitor() update display_info beforehand. In the case that this doesn't happen, the code is unchanged. Do you want I explain the changes in the code here again ? Or do you want to me change the commit message to be more clear ? In the first case, I can write here a detailed explanation. In the second case I can make a longer commit message. Or both? Best Regards, Claudio Suarez.

OK, so I had a bit of a dig around and seems that what we do now > .detect()->drm_get_edid()->drm_connector_update_edid_property()->drm_add_display_info() Yes. I said before that I felt something was wrong when I read the documentation and then the code. To be more explicit now, I expected that drm_connector_update_edid_property() will be done in the fill_modes/get_modes phase instead of when reading the edid. The documentation suggests that but the code reads the edid in the detect phase. Now, since drm_connector_update_edid_property() is called in the detect phase, it is not necessary to keep the edid data in the private connector struct. It is in struct drm_connector from the beginning. But this is topic for another patch. > Now the question is when did that start happening?

The flag drm_display_info.is_hdmi is set in the function drm_add_display_info(), which is called from drm_connector_update_edid_property(). Since commit 5186421cbfe2, drm_get_edid() calls drm_connector_update_edid_property() when reading the edid data from an i2c adapter.
