MIPS: /proc/cpuinfo: always print the supported ISA

2014-01-24T21:39:46+00:00

Currently the supported ISA is only printed on the latest architectures.
Print it also on legacy platforms.

Add support for including VPE and TC ids in /proc/cpuinfo output as
appropriate when MT/SMTC is enabled.

MIPS: Get rid of MIPS I flag and test macros.

2013-07-01T13:10:56+00:00

MIPS I is the ancestor of all MIPS ISA and architecture variants.  Anything
ever build in the MIPS empire is either MIPS I or at least contains MIPS I.
If it's running Linux, that is.

So there is little point in having cpu_has_mips_1 because it will always
evaluate as true - though usually only at runtime.  Thus there is no
point in having the MIPS_CPU_ISA_I ISA flag, so get rid of it.

Little complication: traps.c was using a test for a pure MIPS I ISA as
a test for an R3000-style cp0.  To deal with that, use a check for
cpu_has_3kex or cpu_has_4kex instead.

cpu_has_3kex is a new macro.  At the moment its default implementation is
!cpu_has_4kex but this may eventually change if Linux is ever going to
support the oddball MIPS processors R6000 and R8000 so users of either
of these macros should not make any assumptions.

MIPS: microMIPS: Add configuration option for microMIPS kernel.

2013-05-09T15:55:19+00:00

This adds the option to build the Linux kernel using only the
microMIPS ISA. The resulting kernel binary is, at a minimum,
20% smaller than using the MIPS32R2 ISA.

MIPS: move mips_{set,get}_machine_name() to a more generic place

2013-05-07T23:19:07+00:00

Previously this functionality was only available to users of the mips_machine
api. Moving the code to prom.c allows us to also add a OF wrapper.

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