LoongArch VCPUs have their own separate HW timers. SW timer is to wake up blocked vcpu thread, rather than HW timer emulation. When blocking vcpu scheduled out, SW timer is used to wakeup blocked vcpu thread and injects timer interrupt. It does not care about whether guest timer is in period mode or oneshot mode, and SW timer needs not to be restarted since vcpu has been woken. This patch does not restart SW timer when it is expired. Signed-off-by: Bibo Mao <maobibo@loongson.cn> Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
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.
