[Libre-soc-dev] power-gem5

[Luke Kenneth Casson Leighton]

if anyone is interested, boris shingarov and others are currently
reviewing and walking through the patches to add POWER ISA 64-bit
capability, developed over a year ago, to gem5.

https://gem5-review.googlesource.com/c/public/gem5/+/40887

this was the original work:
https://github.com/power-gem5/gem5/tree/gem5-experimental

it includes work needed to boot a linux initrd + buildroot, but as an
experiment by students that branch removed some capabilities, to save
time.

Sandipan is currently going *gently* through that work, making sure
that it's added incrementally.  userspace only (ELF binaries) is the
first step, adding in 64-bit and making sure that 32-bit, BE and LE
are still functional.

note that no current contributor is planning to add VSX / VMX: it's
too much.  additionally, the power-gem5 decoder is already severely
overloaded.
