[SRU Justfication]
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]
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]
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. |
