Conor Dooley <conor@kernel.org> says: Since one depends on the other, albeit trivially, here's a v4 of the Zbb toolchain dep removal alongside the rewording of Kconfig options I'd sent out before the merge window. I think I like this implementation better than v1, but I couldn't think of a good name for a "public" version of __ALTERNATIVE(), so I used it here directly. Unfortunately "ALTERNATIVE_2_CFG" already exists and I couldn't think of a good way to name an alternative macro that allows for several config options that didn't make the distinction sufficiently clear.. Yell if you have better suggestions than I did. I am a wee bit "worried" that this makes the Kconfig option confusing as it isn't immediately obvious if someone is or is not going to get the toolchain based optimisations. Cheers, Conor. * patches from https://lore.kernel.org/r/20241024-aspire-rectify-9982da6943e5@spud: RISC-V: separate Zbb optimisations requiring and not requiring toolchain support RISC-V: clarify what some RISCV_ISA* config options do Link: https://lore.kernel.org/r/20241024-aspire-rectify-9982da6943e5@spud Signed-off-by: Alexandre Ghiti <alexghiti@rivosinc.com>
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.
