This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1886165] Re: [WD19TB] external DP failed with DRM error message
** Description changed:
[SRU Justfication]
- [Impact]
+ TGL platform can't output external monitor on WD19TB docking.
+ There's no screen on the external monitor.
+ error in dmesg:
+
+ [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe B FIFO
underru
- [Fix]
+ [Fix]
+ According to Intel's suggestion,
+ we need this: https://patchwork.freedesktop.org/series/78909/
+ Also for dependency, the following patches are landed in drm-tip
+ and necessary for support TGL platform:
+
+ * commit f4ece33f51d8 ("drm/i915/tgl+: Fix TBT DPLL fractional divider for
38.4MHz ref clock")
+ * commit a6e96d6948c8 ("drm/i915/tgl+: Use the correct DP_TP_* register
instances in MST encoders")
+ * commit f822a79734e1 ("drm/i915/dc3co: Avoid full modeset when EXITLINE
needs to be changed")
+ * commit 1a7e82efaa8a ("drm/i915/tgl: Add HBR and HBR2+ voltage swing table")
+ * commit 80907edcc6ed ("UBUNTU: SAUCE: drm/i915/bios: add
intel_bios_hdmi_level_shift()")
+ * commit 6df896896c8d ("drm/i915/tgl: Implement WA_16011163337")
+ * commit cb730fe971f0 ("drm/i915/tgl: Update TC DP vswing table")
- [Test]
-
- [Regression Potential]
+ [Test]
+ The WD19TB can output HDMI/DP to external monitor.
+
+ [Regression Potential]
+ Medium, in order to support TGL platform, we also include two patches:
+ drm/i915/bios: add intel_bios_hdmi_level_shift()
+ drm/i915/dc3co: Avoid full modeset when EXITLINE needs to be changed
+ The two patches are not related to TGL, but for dependency.
