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 default-configs/or1k-softmmu.mak | 1 + hw/intc/Makefile.objs | 1 + hw/intc/ompic.c | 179 +++++++++++++++++++++++++++++++++++++++ hw/openrisc/cputimer.c | 64 ++++++++++---- hw/openrisc/openrisc_sim.c | 87 ++++++++++++++----- target/openrisc/cpu.c | 1 - target/openrisc/cpu.h | 7 +- target/openrisc/machine.c | 8 +- target/openrisc/sys_helper.c | 8 +- 9 files changed, 308 insertions(+), 48 deletions(-) create mode 100644 hw/intc/ompic.c -- 2.13.5
