This series adds RISC-V support for KVMTOOL and it is based on the Linux-5.16-rc1. The KVM RISC-V patches have been merged in the Linux kernel since 5.16-rc1. The KVMTOOL RISC-V patches can be found in riscv_master branch at: https//github.com/kvm-riscv/kvmtool.git Changes since v10: - Updated PLIC CLAIM write emulation in PATCH5 to ignore writes when interrupt is disabled for the PLIC context. This behaviour is as-per definition of interrupt completion process in the RISC-V PLIC spec. Changes since v9: - Rebased on recent commit 39181fc6429f4e9e71473284940e35857b42772a - Sync-up headers with Linux-5.16-rc1 Changes since v8: - Rebased on recent commit 2e7380db438defbc5aa24652fe10b7bf99822355 - Sync-up headers with latest KVM RISC-V v20 series which is based on Linux-5.15-rc3 - Fixed PLIC context CLAIM register emulation in PATCH5 Changes since v7: - Rebased on recent commit 25c1dc6c4942ff0949c08780fcad6b324fec6bf7 - Sync-up headers with latest KVM RISC-V v19 series which is based on Linux-5.14-rc3 Changes since v6: - Rebased on recent commit 117d64953228afa90b52f6e1b4873770643ffdc9 - Sync-up headers with latest KVM RISC-V v17 series which is based on Linux-5.12-rc5 Changes since v5: - Sync-up headers with latest KVM RISC-V v16 series which is based on Linux-5.11-rc3 Changes since v4: - Rebased on recent commit 90b2d3adadf218dfc6bdfdfcefe269843360223c - Sync-up headers with latest KVM RISC-V v15 series which is based on Linux-5.10-rc3 Changes since v3: - Rebased on recent commit 351d931f496aeb2e97b8daa44c943d8b59351d07 - Improved kvm_cpu__show_registers() implementation Changes since v2: - Support compiling KVMTOOL for both RV32 and RV64 systems using a multilib toolchain - Fix kvm_cpu__arch_init() for RV32 system Changes since v1: - Use linux/sizes.h in kvm/kvm-arch.h - Added comment in kvm/kvm-arch.h about why PCI config space is 256M - Remove forward declaration of "struct kvm" from kvm/kvm-cpu-arch.h - Fixed placement of DTB and INITRD in guest RAM - Use __riscv_xlen instead of sizeof(unsigned long) in __kvm_reg_id() Anup Patel (8): update_headers: Sync-up ABI headers with Linux-5.16-rc1 riscv: Initial skeletal support riscv: Implement Guest/VM arch functions riscv: Implement Guest/VM VCPU arch functions riscv: Add PLIC device emulation riscv: Generate FDT at runtime for Guest/VM riscv: Handle SBI calls forwarded to user space riscv: Generate PCI host DT node INSTALL | 7 +- Makefile | 24 +- arm/aarch64/include/asm/kvm.h | 56 ++- include/linux/kvm.h | 441 ++++++++++++++++++++- powerpc/include/asm/kvm.h | 10 + riscv/fdt.c | 195 ++++++++++ riscv/include/asm/kvm.h | 128 +++++++ riscv/include/kvm/barrier.h | 14 + riscv/include/kvm/fdt-arch.h | 8 + riscv/include/kvm/kvm-arch.h | 89 +++++ riscv/include/kvm/kvm-config-arch.h | 15 + riscv/include/kvm/kvm-cpu-arch.h | 51 +++ riscv/include/kvm/sbi.h | 48 +++ riscv/ioport.c | 7 + riscv/irq.c | 13 + riscv/kvm-cpu.c | 490 ++++++++++++++++++++++++ riscv/kvm.c | 174 +++++++++ riscv/pci.c | 109 ++++++ riscv/plic.c | 571 ++++++++++++++++++++++++++++ util/update_headers.sh | 2 +- x86/include/asm/kvm.h | 64 +++- 21 files changed, 2497 insertions(+), 19 deletions(-) create mode 100644 riscv/fdt.c create mode 100644 riscv/include/asm/kvm.h create mode 100644 riscv/include/kvm/barrier.h create mode 100644 riscv/include/kvm/fdt-arch.h create mode 100644 riscv/include/kvm/kvm-arch.h create mode 100644 riscv/include/kvm/kvm-config-arch.h create mode 100644 riscv/include/kvm/kvm-cpu-arch.h create mode 100644 riscv/include/kvm/sbi.h create mode 100644 riscv/ioport.c create mode 100644 riscv/irq.c create mode 100644 riscv/kvm-cpu.c create mode 100644 riscv/kvm.c create mode 100644 riscv/pci.c create mode 100644 riscv/plic.c -- 2.25.1
