[PATCH 3/4] drm/i915: Remove platform comments from workarounds
Lucas De Marchi
lucas.demarchi at intel.com
Thu Dec 22 08:25:56 UTC 2022
The comments are redundant to the checks being done to apply the
workarounds and very often get outdated as workarounds need to be
extended to new platforms or steppings. Remove them altogether with
the following matches (platforms extracted from intel_workarounds.c):
find drivers/gpu/drm/i915/ -name '*.c' | xargs sed -i -E \
's/(Wa.*):(bdw|chv|bxt|glk|skl|kbl|cfl|cfl|whl|cml|aml|chv|cl|bw|ctg|elk|ilk|snb|dg|pvc|g4x|ilk|gen|glk|kbl|cml|glk|kbl|cml|hsw|icl|ehl|ivb|hsw|ivb|vlv|kbl|pvc|rkl|dg|adl|skl|skl|bxt|blk|cfl|cnl|glk|snb|tgl|vlv|xehpsdv).*/\1/'
find drivers/gpu/drm/i915/ -name '*.c' | xargs sed -i -E \
's/(Wa.*):(bdw|chv|bxt|glk|skl|kbl|cfl|cfl|whl|cml|aml|chv|cl|bw|ctg|elk|ilk|snb|dg|pvc|g4x|ilk|gen|glk|kbl|cml|glk|kbl|cml|hsw|icl|ehl|ivb|hsw|ivb|vlv|kbl|pvc|rkl|dg|adl|skl|skl|bxt|blk|cfl|cnl|glk|snb|tgl|vlv|xehpsdv).*\*\//\1
There were a few false positives that included the workaround
description. Those were manually patched.
