-Subject: drm/amd/display: Reduce number of arguments of dcn30's
- CalculatePrefetchSchedule()
-
-After an innocuous optimization change in clang-22,
-dml30_ModeSupportAndSystemConfigurationFull() is over the 2048 byte
-stack limit for display_mode_vba_30.c.
-
-  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (2096) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
-   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
-        |      ^
-
-With clang-21, this function was already close to the limit:
-
-  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (1912) exceeds limit (1586) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
-   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
-        |      ^
-
-CalculatePrefetchSchedule() has a large number of parameters, which must
-be passed on the stack. Most of the parameters between the two callsites
-are the same, so they can be accessed through the existing mode_lib
-pointer, instead of being passed as explicit arguments. Doing this
-reduces the stack size of dml30_ModeSupportAndSystemConfigurationFull()
-from 2096 bytes to 1912 bytes with clang-22.

-Subject: drm/amd/display: Reduce number of arguments of dcn30's
- CalculateWatermarksAndDRAMSpeedChangeSupport()
-
-CalculateWatermarksAndDRAMSpeedChangeSupport() has a large number of
-parameters, which must be passed on the stack. Most of the parameters
-between the two callsites are the same, so they can be accessed through
-the existing mode_lib pointer, instead of being passed as explicit
-arguments. Doing this reduces the stack size of
-dml30_ModeSupportAndSystemConfigurationFull() from 1912 bytes to 1840
-bytes building for x86_64 with clang-22, helping stay under the 2048
-byte limit for display_mode_vba_30.c.
-
-Additionally, now that there is a pointer to mode_lib->vba available,
-use 'v' consistently throughout the entire function.

+Subject: drm/amd/display: Reduce number of arguments of dcn30's
+ CalculateWatermarksAndDRAMSpeedChangeSupport()
+
+CalculateWatermarksAndDRAMSpeedChangeSupport() has a large number of
+parameters, which must be passed on the stack. Most of the parameters
+between the two callsites are the same, so they can be accessed through
+the existing mode_lib pointer, instead of being passed as explicit
+arguments. Doing this reduces the stack size of
+dml30_ModeSupportAndSystemConfigurationFull() from 1912 bytes to 1840
+bytes building for x86_64 with clang-22, helping stay under the 2048
+byte limit for display_mode_vba_30.c.
+
+Additionally, now that there is a pointer to mode_lib->vba available,
+use 'v' consistently throughout the entire function.

+Subject: drm/amd/display: Reduce number of arguments of dcn30's
+ CalculatePrefetchSchedule()
+
+After an innocuous optimization change in clang-22,
+dml30_ModeSupportAndSystemConfigurationFull() is over the 2048 byte
+stack limit for display_mode_vba_30.c.
+
+  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (2096) exceeds limit (2048) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
+   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
+        |      ^
+
+With clang-21, this function was already close to the limit:
+
+  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn30/display_mode_vba_30.c:3529:6: warning: stack frame size (1912) exceeds limit (1586) in 'dml30_ModeSupportAndSystemConfigurationFull' [-Wframe-larger-than]
+   3529 | void dml30_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
+        |      ^
+
+CalculatePrefetchSchedule() has a large number of parameters, which must
+be passed on the stack. Most of the parameters between the two callsites
+are the same, so they can be accessed through the existing mode_lib
+pointer, instead of being passed as explicit arguments. Doing this
+reduces the stack size of dml30_ModeSupportAndSystemConfigurationFull()
+from 2096 bytes to 1912 bytes with clang-22.
