docs: move sparc documentation under Documentation/arch/

2023-03-30T19:00:34Z

Architecture-specific documentation is being moved into Documentation/arch/ as a way of cleaning up the top-level documentation directory and making the docs hierarchy more closely match the source hierarchy. Move Documentation/sparc into arch/ and fix all in-tree references. Cc: "David S. Miller" Signed-off-by: Jonathan Corbet

docs: add arch doc directories to the index

Now that several arch documents were converted to ReST, add their indexes to Documentation/index.rst and remove the :orphan: from them. Signed-off-by: Mauro Carvalho Chehab

docs: sparc: convert to ReST

2019-05-09T00:13:35Z

Rename the sparc documentation files to ReST, add an index for them and adjust in order to produce a nice html output via the Sphinx build system. There is an except from a document under oradax dir. It doesn't seem to make much sense to convert this one to ReST, so let's add it as an included document. At its new index.rst, let's add a :orphan: while this is not linked to the main index.rst file, in order to avoid build warnings. Signed-off-by: Mauro Carvalho Chehab Signed-off-by: David S. Miller

sparc64: Add support for ADI (Application Data Integrity)

2018-03-18T14:38:48Z

ADI is a new feature supported on SPARC M7 and newer processors to allow hardware to catch rogue accesses to memory. ADI is supported for data fetches only and not instruction fetches. An app can enable ADI on its data pages, set version tags on them and use versioned addresses to access the data pages. Upper bits of the address contain the version tag. On M7 processors, upper four bits (bits 63-60) contain the version tag. If a rogue app attempts to access ADI enabled data pages, its access is blocked and processor generates an exception. Please see Documentation/sparc/adi.txt for further details. This patch extends mprotect to enable ADI (TSTATE.mcde), enable/disable MCD (Memory Corruption Detection) on selected memory ranges, enable TTE.mcd in PTEs, return ADI parameters to userspace and save/restore ADI version tags on page swap out/in or migration. ADI is not enabled by default for any task. A task must explicitly enable ADI on a memory range and set version tag for ADI to be effective for the task.

sparc64: Oracle DAX driver

2018-01-22T16:17:16Z

DAX is a coprocessor which resides on the SPARC M7 (DAX1) and M8 (DAX2) processor chips, and has direct access to the CPU's L3 caches as well as physical memory. It can perform several operations on data streams with various input and output formats. This driver provides a transport mechanism and has limited knowledge of the various opcodes and data formats. A user space library provides high level services and translates these into low level commands which are then passed into the driver and subsequently the hypervisor and the coprocessor. The library is the recommended way for applications to use the coprocessor, and the driver interface is not intended for general use.
