MIPS: Probe for and report hardware virtualization support.

2013-02-19T08:36:36+00:00

The presence of the MIPS Virtualization Application-Specific Extension
is indicated by CP0_Config3[23].  Probe for this and report it in
/proc/cpuinfo.

MIPS: Add printing of ISA version in cpuinfo.

2013-02-15T22:07:38+00:00

Display the MIPS ISA version release in the /proc/cpuinfo file.

[ralf@linux-mips.org: Add support for MIPS I ... IV legacy architecture
revisions.  Also differenciate between MIPS32 and MIPS64 versions instead
of lumping them together as just r1 and r2.

Note to application programmers: this indicates the CPU's ISA level
It does not imply the current execution environment does support it.  For
example an O32 application seeing "mips64r2" would still be restricted by
by the execution environment to 32-bit - but the kernel could run mips64r2
code.  The same for a 32-bit kernel running on a 64-bit processor.  This
field doesn't include ASEs or optional architecture modules nor other
detailed flags such as the availability of an FPU.]

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

MIPS: Add detection of DSP ASE Revision 2.

2012-10-11T09:05:03+00:00

[ralf@linux-mips.org: This patch really only detects the ASE and passes its
existence on to userland via /proc/cpuinfo.  The DSP ASE Rev 2. adds new
resources but no resources that would need management by the kernel.]

MIPS: perf: Add cpu feature bit for PCI (performance counter interrupt)

2012-10-11T09:04:34+00:00

The PCI (Program Counter Interrupt) bit in the "cause" register
is mandatory for MIPS32R2 cores, but has also been added to some R1
cores (BMIPS5000). This change adds a cpu feature bit to make it
easier to check for and use this feature.

MIPS: Replace 'kernel_uses_smartmips_rixi' with 'cpu_has_rixi'.

2012-09-13T22:00:34+00:00

Remove usage of the 'kernel_uses_smartmips_rixi' macro from all files
and use new 'cpu_has_rixi' instead.

MIPS: Add base architecture support for RI and XI.

2012-09-13T21:55:53+00:00

Originally both Read Inhibit (RI) and Execute Inhibit (XI) were
supported by the TLB only for a SmartMIPS core. The MIPSr3(TM)
Architecture now defines an optional feature to implement these
TLB bits separately. Support for one or both features can be
checked by looking at the Config3.RXI bit.
