[PATCH 05/22] drm/amd/display: Move Mode Support Prefetch Checks To Its Own Function

Zaeem Mohamed zaeem.mohamed at amd.com
Tue Apr 15 14:58:51 UTC 2025


From: Austin Zheng <Austin.Zheng at amd.com>

[Why]
Large stack size observed in DCN4 mode support when compiling with clang.
Additional instrumentation added by compiler adds to stack size.
dml_core_mode_support ends up going over the stack size limit
due to the size of the function.

[How]
Move checks and calculations for prefetch to its own function.
