[Qemu-devel] [PATCH 00/12] implement features required in MIPS64 Release 6

[Leon Alrae]

This patch series implement set of features whose presence became mandatory in
MIPS64R6:
- KScratch registers,
- Read-Inhibit and Execute-Inhibit page protection bits,
- TLB Invalidate (TLBINV and TLBINVF instructions),
- BadInstr and BadInstrP.
The last patch in the series enables them in MIPS64R6 CPU config therefore
this series should be applied on the top of pending patches introducing
MIPS64R6 Instruction Set.

Commits briefly describe each feature. For more details please refer to the
Volume III (The MIPS64 and microMIPS64 Privileged Resource Architecture) and
Volume II (The MIPS64 Instruction Set) of MIPS documents available at:
http://www.imgtec.com/mips/architectures/mips64.asp

This patchset focuses on features which existed before Release 6. It does not
contain new MIPS64R6 features like forbidden slot, SBRI, reserved fields.
This will come as a separate patchset soon.

Any comments / suggestions are more than welcome!

Thanks,
Leon
