Linux kernel source tree
9f4c6256d0
When building with tip of tree Clang, there are some new instances of
-Wframe-larger-than from the new display code (which become fatal with
CONFIG_WERROR=y):
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_shared.c:754:6: error: stack frame size (2488) exceeds limit (2048) in 'dml2_core_shared_mode_support' [-Werror,-Wframe-larger-than]
754 | bool dml2_core_shared_mode_support(struct dml2_core_calcs_mode_support_ex *in_out_params)
| ^
drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/dml21/src/dml2_core/dml2_core_shared.c:9834:6: error: stack frame size (2152) exceeds limit (2048) in 'dml2_core_shared_mode_programming' [-Werror,-Wframe-larger-than]
9834 | bool dml2_core_shared_mode_programming(struct dml2_core_calcs_mode_programming_ex *in_out_params)
| ^
2 errors generated.
These warnings do not occur when CONFIG_K{A,C,M}SAN are disabled, so add
$(frame_warn_flag) to dml2_core_shared.o's CFLAGS, which was added in

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
