Currently, the sbi_pmu_test continues if the exception type is illegal instruction because access to hpmcounter will generate that. However illegal instruction exception may occur due to the other reasons which should result in test assertion. Use the stval to decode the exact type of instructions and which csrs are being accessed if it is csr access instructions. Assert in all cases except if it is a csr access instructions that access valid PMU related registers. Take this opportunity to remove the CSR_CYCLEH reference as the test is compiled for RV64 only.

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.
