[PATCH v3 00/12] Add riscv kvm accel support
by Yifei Jiang 09 Jan '22

09 Jan '22

This series adds both riscv32 and riscv64 kvm support, and implements migration based on riscv. Because of RISC-V KVM has been merged into the Linux master, so this series are changed from RFC to patch. Several steps to use this: 1. Build emulation $ ./configure --target-list=riscv64-softmmu $ make -j$(nproc) 2. Build kernel 3. Build QEMU VM Cross built in riscv toolchain. $ PKG_CONFIG_LIBDIR=<toolchain pkgconfig path> $ export PKG_CONFIG_SYSROOT_DIR=<toolchain sysroot path> $ ./configure --target-list=riscv64-softmmu --enable-kvm \ --cross-prefix=riscv64-linux-gnu- --disable-libiscsi --disable-glusterfs \ --disable-libusb --disable-usb-redir --audio-drv-list= --disable-opengl \ --disable-libxml2 $ make -j$(nproc) 4. Start emulation $ ./qemu-system-riscv64 -M virt -m 4096M -cpu rv64,x-h=true -nographic \ -name guest=riscv-hyp,debug-threads=on \ -smp 4 \ -bios ./fw_jump.bin \ -kernel ./Image \ -drive file=./hyp.img,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 \ -append "root=/dev/vda rw console=ttyS0 earlycon=sbi" 5. Start kvm-acceled QEMU VM in emulation $ ./qemu-system-riscv64 -M virt,accel=kvm -m 1024M -cpu host -nographic \ -name guest=riscv-guset \ -smp 2 \ -bios none \ -kernel ./Image \ -drive file=./guest.img,format=raw,id=hd0 \ -device virtio-blk-device,drive=hd0 \ -append "root=/dev/vda rw console=ttyS0 earlycon=sbi" Changes since patch v2 - Create a macro for get and put timer csr. - Remove M-mode PLIC contexts when kvm is enabled. - Add get timer frequency. - Move cpu_host_load to vmstate_kvmtimer. Changes since patch v1 - Rebase on recent commit a216e7cf119c91ffdf5931834a1a030ebea40d70 - Sync-up headers with Linux-5.16-rc4. - Fixbug in kvm_arch_init_vcpu. - Create a macro for get and put regs csr. - Start kernel directly when kvm_enabled. - Use riscv_cpu_set_irq to inject KVM interrupts. - Use the Semihosting Console API for RISC-V kvm handle sbi. - Update vmstate_riscv_cpu version id. Placing kvm_timer into a subsection. Changes since RFC v6 - Rebase on recent commit 8627edfb3f1fca24a96a0954148885c3241c10f8 - Sync-up headers with Linux-5.16-rc1 Changes since RFC v5 - Rebase on QEMU v6.1.0-rc1 and kvm-riscv linux v19. - Move kvm interrupt setting to riscv_cpu_update_mip(). - Replace __u64 with uint64_t. Changes since RFC v4 - Rebase on QEMU v6.0.0-rc2 and kvm-riscv linux v17. - Remove time scaling support as software solution is incomplete. Because it will cause unacceptable performance degradation. and We will post a better solution. - Revise according to Alistair's review comments. - Remove compile time XLEN checks in kvm_riscv_reg_id - Surround TYPE_RISCV_CPU_HOST definition by CONFIG_KVM and share it between RV32 and RV64. - Add kvm-stub.c for reduce unnecessary compilation checks. - Add riscv_setup_direct_kernel() to direct boot kernel for KVM. Changes since RFC v3 - Rebase on QEMU v5.2.0-rc2 and kvm-riscv linux v15. - Add time scaling support(New patches 13, 14 and 15). - Fix the bug that guest vm can't reboot. Changes since RFC v2 - Fix checkpatch error at target/riscv/sbi_ecall_interface.h. - Add riscv migration support. Changes since RFC v1 - Add separate SBI ecall interface header. - Add riscv32 kvm accel support.

[PATCH] do not report generic OPERATION_FAILED error when calling virConnectOpenAuth()
by Ani Sinha 07 Jan '22

07 Jan '22

virConnectOpenAuth() calls virConnectOpenInternal(). This later function generates fine grained errors arising from various failure conditions that are more accurate than a "catch all" broader VIR_ERR_OPERATION_FAILED error that the callers of this function generates. Remove the broader error so that more specific errors can be caught and processed.

[PATCH] src: Don't check for retval of g_strsplit()
by Michal Privoznik 07 Jan '22

07 Jan '22

The g_strsplit() function can return NULL if and only if either the input string is NULL or delimiter is NULL or an empty string. In neither of places we call it any of the conditions is true and thus we don't need to check for the return value.

[libvirt PATCH v4 00/19] qemu: Introduce hvf domain type for Hypervisor.framework
by Andrea Bolognani 07 Jan '22

07 Jan '22

In order to hopefully address [libvirt#147] at long last, I've picked up Roman's patches from 2018 and attempted to forward-port them. More specifically, I've used the [roolebo/hvf-domain] branch as a starting point, since it seems to contain a few improvements over [v2] and was just easier to pick up. The code is mostly his own, so I've retained the existing authorship information, but I've dropped Reviewed-by tags for commits that have been modified in non-trivial ways. I've applied very minimal style tweaks along the way, but overall I've tried to modify the existing patches as little as possible. I've added a few changes of my own, which I've marked as "fixup!" when I felt that they should be squashed into the previous patch rather than existing as separate commits. The new test cases, such as they are, pass, and no regressions to KVM support appear to have been introduced in the process. I don't currently have access to a machine running macOS, so I can't verify that it's actually possible to start a hardware-accelerated VM. Changes from [v3]: * reintroduced the patch that was missing in the initial version of the forward-port; * converted the documentation to reStructuredText and trimmed it significantly; * reworked virQEMUCapsAccelStr() based on Dan's suggestions; * reworked macOS support in the test suite based on Dan's suggestions; * fixed a few minor issues found while doing the above. Changes from [v2]: * rebased on top of master; * added a couple of simple test cases.
