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 Restructured Text 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.

There are two generations of tlb operation instruction for C-SKY.
First generation is use mcr register and it need software do more
things, second generation is use specific instructions, eg:
tlbi.va, tlbi.vas, tlbi.alls
We implemented the following functions:
- flush_tlb_range (a range of entries)
- flush_tlb_page (one entry)
Above functions use asid from vma->mm to invalid tlb entries and
we could use tlbi.vas instruction for newest generation csky cpu.
- flush_tlb_kernel_range
- flush_tlb_one
Above functions don't care asid and it invalid the tlb entries only
with vpn and we could use tlbi.vaas instruction for newest generat-
ion csky cpu.
