If a sink is removed in the middle of payload addition drm_dp_add_payload_part1() will fail as expected, either not finding the payload's MST port or failing the payload-add AUX transaction. Based on the above tune the error message down to a debug messge. Cc: Lyude Paul <lyude@redhat.com> Reviewed-by:

It's not necessary to carry separate suspended status information in intel_runtime_pm struct as this information is already in underlying device structure.

Remove the i915 specific i2c-N symlink from HDMI connectors. This was added to sort of mirror the DP connectors that alreayd had their aux ch based i2c adapter sitting beneath them in the sysfs hierarchy. But now that we have the standard "ddc" symlink approach provided by the core let's switch to that fully. I don't think anything beyond igt depends on this. Signed-off-by:

Remove the mostly redundant hdmi->ddc_bus. The only thing that needs it anymore is get_encoder_by_ddc_bus(), but that can be replaced with a slight detour through attached_connector+intel_gmbus_get_adapter(). Signed-off-by:

We already populate connector->ddc for HDMI ports, but so far we've not taken full advantage of it. Do that by eliminating a bunch of intel_gmbus_get_adapter() lookups. Signed-off-by:

Populate connector->ddc, and thus create the "ddc" symlink in sysfs for analog DP SST connectors. Let's also reorder intel_dp_aux_init() vs. drm_connector_init_with_ddc() a bit to make sure the i2c aux ch is at least somewhat populated before we pass it on, though drm_connector_init_with_ddc() does not actually do anything with it.

Populate connector->ddc, and thus create the "ddc" symlink in sysfs for analog VGA connectors. As a bonus we can replace a bunch of intel_gmbus_get_adapter() lookups with just the connector->ddc pointer. Sadly one extra lookup still remains due to the g4x DVI-I shenanigans. We could perhaps consider borrowing the ddc proxy idea from SDVO to deal with that in a perhaps nicer way, but can't really be bothered right now at least. Also not sure exposing such a dual ddc bus to userspace would be quite wise. Signed-off-by:

Rename the various names we've used for the DDC bus i2c adapter ("i2c", "adapter", etc.) to just "ddc". This differentiates it from the various other i2c busses we might have (DSI panel stuff, DVO control bus, etc.). v2: Don't add a bogus drm_get_edid() call (Jani) Reviewed-by: -
Ville Syrjälä authored
Currently drm_sysfs_connector_add() attempts to register the "ddc" symlink (based one connector->ddc) before the driver's .early_register() hook has been called. That is too early for i915 which only fully registers the aux ch and associated i2c bus from said hook (to prevent half initialized stuff getting exposed to userspace). This causes my attempt at using drm_connector_init_with_ddc() to fail, and the entire connector disappears from sysfs on account of sysfs_create_link() failing. To fix that split the sysfs symlink stuff into separate functions (drm_sysfs_connector_add_late() and drm_sysfs_connector_remove_early()) which are called on the opposite side of the .later_register() and .early_unregister() hooks.

Use the standard onion peeling approach and call drm_debugfs_connector_remove() and drm_sysfs_connector_remove() in the reverse order in drm_connector_unregister() than what we called their add counterpartse in drm_connector_register(). The error unwiding in drm_connector_register() is already doing this the correct way around. Signed-off-by:

pic_width when written into the PPS register is divided by the no. of vdsc instances first but the actual variable that we compare it to does not change i.e vdsc_cfg->pic_width hence when reading the register back for pic_width it needs to be multiplied by num_vdsc_instances rather than being divided.

We always check whether combo PHYs need to be re-initialized after disabling DC states, which leads to log spam. Switch things around so that we only log something when we actually have to re-initialized a PHY. The log spam was exacerbated by commit 41b4c7fe ("drm/i915: Disable DC states for all commits") since we now disable DC states far more often. Signed-off-by:

Apparently Acer Chromebook C740 (BDW-ULT) doesn't have the eDP HPD line properly connected, and thus fails the new HPD check during eDP probe. The result is that we lose the eDP output. I suspect all such machines would be Chromebooks or other Linux exclusive systems as the Windows driver likely wouldn't work either. I did check a few other BDW machines here and those do have eDP HPD connected, one of them even is a different Chromebook (Samus). To account for these funky machines let's skip the HPD check when it looks like the eDP port is the only one using that specific AUX channel. In case of multiple ports sharing the same AUX CH (eg. on Asrock B250M-HDV) we still do the check and thus should correctly ignore the eDP port in favor of the other DP port (usually a DP->VGA converter). v2: Don't oops during list iteration Cc: stable@vger.kernel.org Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/9264 Fixes: cfe5bdfb ("drm/i915: Check HPD live state during eDP probe") Signed-off-by:
