Patch add "mem_access" event to sysfs. This as-is not a raw event supported by Power8 pmu. Instead, it is formed based on raw event encoding specificed in isa207-common.h. Primary PMU event used here is PM_MRK_INST_CMPL. This event tracks only the completed marked instructions. Random sampling mode (MMCRA[SM]) with Random Instruction Sampling (RIS) is enabled to mark type of instructions. With Random sampling in RLS mode with PM_MRK_INST_CMPL event, the LDST /DATA_SRC fields in SIER identifies the memory hierarchy level (eg: L1, L2 etc) statisfied a data-cache miss for a marked instruction.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
