When building, the following warnings will appear. " pci_irq.c: In function ‘mlx5_ctrl_irq_request’: pci_irq.c:494:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] pci_irq.c: In function ‘mlx5_irq_request_vector’: pci_irq.c:561:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] eq.c: In function ‘comp_irq_request_sf’: eq.c:897:1: warning: the frame size of 1080 bytes is larger than 1024 bytes [-Wframe-larger-than=] irq_affinity.c: In function ‘irq_pool_request_irq’: irq_affinity.c:74:1: warning: the frame size of 1048 bytes is larger than 1024 bytes [-Wframe-larger-than=] " These warnings indicate that the stack frame size exceeds 1024 bytes in these functions. To resolve this, instead of allocating large memory buffers on the stack, it is better to use kvzalloc to allocate memory dynamically on the heap. This approach reduces stack usage and eliminates these frame size warnings.

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.
