Linux kernel source tree

Some registers such as LOONGARCH_CSR_ESTAT and LOONGARCH_CSR_GINTC are partly cleared with function _kvm_setcsr(). This comes from the hardware specification, some bits are read only in VM mode, and however they can be written in host mode. So they are partly cleared in VM mode, and can be fully cleared in host mode. These read only bits show pending interrupt or exception status. When VM reset, the read-only bits should be cleared, otherwise vCPU will receive unknown interrupts in boot stage. Here registers LOONGARCH_CSR_ESTAT/LOONGARCH_CSR_GINTC are fully cleared in ioctl KVM_REG_LOONGARCH_VCPU_RESET vCPU reset path.

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.
