Re: [Intel-gfx] [PATCH 02/14] drm: handle HDP and polled connectors separately

Instead of reusing the polling code for hdp handling, split them up. This has a few consequences:

• Don't touch HDP capable connectors in the poll loop.
• Only touch HDP capable connectors in drm_helper_hpd_irq_event.
• Run the HDP handling directly instead of going through a work item - all callers already call drm_helper_hpd_irq_event from process context without holding the mode_config mutex.

"HPD".

• /* if this is HPD or polled don't check it -
  

•    TV out for instance */
  

• if (!connector->polled)
  

• /* Ignore HDP capable connectors and connectors where we don't
  

•  * want any hotplug detection at all for polling. */
  

• if (!connector->polled || connector->polled == DRM_CONNECTOR_POLL_HPD)
  

Here too. Also in the subject.
