When changing a partition table entry on POWER9, we do a particular form of the tlbie instruction which flushes all TLBs and caches of the partition table for a given logical partition ID (LPID). This instruction has a field in the instruction word, labelled R (radix), which should be 1 if the partition was previously a radix partition and 0 if it was a HPT partition. This implements that logic. Signed-off-by: Paul Mackerras <paulus@ozlabs.org> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
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.
