For those PMU system registers defined in sys_reg_descs[], use macro PMU_SYS_REG() / PMU_PMEVCNTR_EL0 / PMU_PMEVTYPER_EL0 to define them, and later two macros call macro PMU_SYS_REG() actually. Currently the input parameter of PMU_SYS_REG() is another macro which is calculation formula of the value of system registers, so for example, if we want to "SYS_PMINTENSET_EL1" as the name of sys register, actually the name we get is as following: (((3) << 19) | ((0) << 16) | ((9) << 12) | ((14) << 8) | ((1) << 5)) The name of system register is used in some tracepoints such as trace_kvm_sys_access(), if not set correctly, we need to analyze the inaccurate name to get the exact name (which also is inconsistent with other system registers), and also the inaccurate name occupies more space. To fix the issue, use the name as a input parameter of PMU_SYS_REG like MTE_REG or EL2_REG.

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.
