820ccf8c - drm/amd/display: Respect user's CONFIG_FRAME_WARN more for dml files

Fri, 31 Jan 2025 22:31:19 +0000

drm/amd/display: Respect user's CONFIG_FRAME_WARN more for dml filesCurrently, there are several files in drm/amd/display that aim to have ahigher -Wframe-larger-than value to avoid instances of that warning witha lower value from the user's configuration. However, with the way thatit is currently implemented, it does not respect the user's request viaCONFIG_FRAME_WARN for a higher stack frame limit, which can cause painwhen new instances of the warning appear and break the build due toCONFIG_WERROR.Adjust the logic to switch from a hard coded -Wframe-larger-than valueto only using the value as a minimum clamp and deferring to therequested value from CONFIG_FRAME_WARN if it is higher.Suggested-by: Harry Wentland Reported-by: Greg Kroah-Hartman Closes: https://lore.kernel.org/2025013003-audience-opposing-7f95@gregkh/Signed-off-by: Nathan Chancellor Signed-off-by: Alex Deucher List of files: /linux-6.15/drivers/gpu/drm/amd/display/dc/dml/Makefile
