[PATCH 2/5] drm/i915/psr: Move writing early transport pipe src

Jouni Högander jouni.hogander at intel.com
Tue Mar 19 12:33:24 UTC 2024


Currently PIPE_SRCSZ_ERLY_TPT is written in
intel_display.c:intel_set_pipe_src_size. This doesn't work as
intel_set_pipe_src_size is called only on modeset.

Bspec: 68927

Fixes: 3291bbb93e16 ("drm/i915/psr: Configure PIPE_SRCSZ_ERLY_TPT for psr2 early transport")
