This series adds multi-socket support for RISC-V virt machine and RISC-V spike machine. The multi-socket support will help us improve various RISC-V operating systems, firmwares, and bootloader to support RISC-V NUMA systems.
These patch can be found in riscv_multi_socket_v3 branch at: https://github.com/avpatel/qemu.git To try this patches, we will need: Linux multi-PLIC improvements support which can be found in plic_imp_v2 branch at: https://github.com/avpatel/linux.git Changes since v2: - Dropped PATCH1 as it is not required any more - Added "multi-socket" sub-option for Spike and Virt machine which can be used to enable/disable mult-socket support Changes since v1: - Fixed checkpatch errors and warnings - Added PATCH1 for knowning whether "sockets" sub-option was specified - Remove SPIKE_CPUS_PER_SOCKET_MIN and SPIKE_CPUS_PER_SOCKET_MAX in PATCH3 - Remove VIRT_CPUS_PER_SOCKET_MIN and VIRT_CPUS_PER_SOCKET_MAX in PATCH5 Anup Patel (4): hw/riscv: Allow creating multiple instances of CLINT hw/riscv: spike: Allow creating multiple sockets hw/riscv: Allow creating multiple instances of PLIC hw/riscv: virt: Allow creating multiple sockets hw/riscv/sifive_clint.c | 20 +- hw/riscv/sifive_e.c | 4 +- hw/riscv/sifive_plic.c | 24 +- hw/riscv/sifive_u.c | 4 +- hw/riscv/spike.c | 273 +++++++++++------ hw/riscv/virt.c | 523 ++++++++++++++++++-------------- include/hw/riscv/sifive_clint.h | 7 +- include/hw/riscv/sifive_plic.h | 12 +- include/hw/riscv/spike.h | 13 +- include/hw/riscv/virt.h | 11 +- 10 files changed, 548 insertions(+), 343 deletions(-) -- 2.25.1
