Include tests that check for rejection in erroneous cases, like unbalanced IRQ-disabled counts, within and across subprogs, invalid IRQ flag state or input to kfuncs, behavior upon overwriting IRQ saved state on stack, interaction with sleepable kfuncs/helpers, global functions, and out of order restore. Include some success scenarios as well to demonstrate usage. #128/1 irq/irq_save_bad_arg:OK #128/2 irq/irq_restore_bad_arg:OK #128/3 irq/irq_restore_missing_2:OK #128/4 irq/irq_restore_missing_3:OK #128/5 irq/irq_restore_missing_3_minus_2:OK #128/6 irq/irq_restore_missing_1_subprog:OK #128/7 irq/irq_restore_missing_2_subprog:OK #128/8 irq/irq_restore_missing_3_subprog:OK #128/9 irq/irq_restore_missing_3_minus_2_subprog:OK #128/10 irq/irq_balance:OK #128/11 irq/irq_balance_n:OK #128/12 irq/irq_balance_subprog:OK #128/13 irq/irq_global_subprog:OK #128/14 irq/irq_restore_ooo:OK #128/15 irq/irq_restore_ooo_3:OK #128/16 irq/irq_restore_3_subprog:OK #128/17 irq/irq_restore_4_subprog:OK #128/18 irq/irq_restore_ooo_3_subprog:OK #128/19 irq/irq_restore_invalid:OK #128/20 irq/irq_save_invalid:OK #128/21 irq/irq_restore_iter:OK #128/22 irq/irq_save_iter:OK #128/23 irq/irq_flag_overwrite:OK #128/24 irq/irq_flag_overwrite_partial:OK #128/25 irq/irq_ooo_refs_array:OK #128/26 irq/irq_sleepable_helper:OK #128/27 irq/irq_sleepable_kfunc:OK #128 irq:OK Summary: 1/27 PASSED, 0 SKIPPED, 0 FAILED Acked-by: Eduard Zingerman <eddyz87@gmail.com> Signed-off-by: Kumar Kartikeya Dwivedi <memxor@gmail.com> Link: https://lore.kernel.org/r/20241204030400.208005-8-memxor@gmail.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>
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.
