[Qemu-devel] [PATCH 0/5] OpenRISC SMP Support


From: Stafford Horne
Subject: [Qemu-devel] [PATCH 0/5] OpenRISC SMP Support
Date: Wed, 23 Aug 2017 14:57:08 +0900

Hello,

This series adds SMP support for OpenRISC.  The platform is based on the
work that Stefan Kristiansson did around 2012 implemented in Verilog and
run on FPGAs.  I have been working to upstream this work, these are my QEMU
patches I have been used to help with testing.

I have documented the platform in the OpenRISC 1.2 specification proposal
available here:
  
https://github.com/stffrdhrn/doc/raw/arch-1.2-proposal/openrisc-arch-1.2-rev0.pdf

My latest kernel patches are available here:
  https://github.com/stffrdhrn/linux.git openrisc-4.13-smp-qspinlock

Stafford Horne (5):
  openrisc/ompic: Add OpenRISC Multicore PIC (OMPIC)
  target/openrisc: Make coreid and numcores configurable in state
  openrisc/cputimer: Perparation for Multicore
  openrisc: Initial SMP support
  openrisc: Only kick cpu on timeout, not on update
