Subject: [Intel-gfx] [PATCH 00/11] drm/i915/tc: Add a workaround for an IOM/TCSS firmware hang issue
Date: Wed, 26 Apr 2023 19:52:54 +0300	[thread overview]
Message-ID: <20230426165305.2049341-1-imre.deak@intel.com> (raw)

If a TypeC/DP-alt output is not disabled in time some IOM/TCSS firmware
component will time-out and block at least the PCI power management
operations for other PCI GFX devices. This patchset adds a workaround
that performs an in-kernel modeset (either disabling or switching to
TBT-alt mode) on such connectors to work around this issue.

Imre Deak (11):
  drm/i915: Fix PIPEDMC disabling for a bigjoiner configuration
  drm/i915: Make the CRTC wrt. CSC state consistent during
    sanitize-disabling
  drm/i915: Update connector atomic state before crtc sanitize-disabling
  drm/i915: Factor out set_encoder_for_connector()
  drm/i915: Add support for disabling any CRTCs during HW
    readout/sanitization
  drm/i915/dp: Add link training debug and error printing helpers
  drm/i915/dp: Convert link training error to debug message on
    disconnected sink
  drm/i915/dp: Prevent link training fallback on disconnected port
  drm/i915/dp: Factor out intel_dp_get_active_pipes()
  drm/i915: Factor out call_with_modeset_ctx()
  drm/i915/tc: Reset TypeC PHYs left enabled in DP-alt mode after the
    sink disconnects
