This patch provide a basic PMU, riscv_base_pmu, which supports two general hardware event, instructions and cycles. Furthermore, this PMU serves as a reference implementation to ease the portings in the future. riscv_base_pmu should be able to run on any RISC-V machine that conforms to the Priv-Spec. Note that the latest qemu model hasn't fully support a proper behavior of Priv-Spec 1.10 yet, but work around should be easy with very small fixes. Please check https://github.com/riscv/riscv-qemu/pull/115 for future updates.

README
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. See Documentation/00-INDEX for a list of what is contained in each file. 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.
