Peter Maydell authoredRISC-V Patches for the 5.0 Soft Freeze, Part 5 This tag contains the last of the patches I'd like to target for the 5.0 soft freeze. At this point we're mostly collecting fixes, but there are a few new features. The changes include: * An OpenSBI update, including the various bits necessary to put CI together and an image for the 32-bit sifive_u board. * A fix that disallows TSR when outside of machine mode. * A fix for VS-mode interrupt forwarding. # gpg: Signature made Tue 17 Mar 2020 03:59:58 GMT # gpg: using RSA key 2B3C3747446843B24A943A7A2E1319F35FBB1889 # gpg: issuer "palmer@dabbelt.com" # gpg: Good signature from "Palmer Dabbelt <palmer@dabbelt.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmer@sifive.com>" [unknown] # gpg: aka "Palmer Dabbelt <palmerdabbelt@google.com>" [unknown] # gpg: WARNING: This key is not certified with a trusted signature! # gpg: There is no indication that the signature belongs to the owner. # Primary key fingerprint: 00CE 76D1 8349 60DF CE88 6DF8 EF4C A150 2CCB AB41 # Subkey fingerprint: 2B3C 3747 4468 43B2 4A94 3A7A 2E13 19F3 5FBB 1889 * remotes/palmer/tags/riscv-for-master-5.0-sf5: target/riscv: Fix VS mode interrupts forwarding. gitlab-ci.yml: Add jobs to build OpenSBI firmware binaries riscv: sifive_u: Update BIOS_FILENAME for 32-bit roms: opensbi: Add 32-bit firmware image for sifive_u machine roms: opensbi: Upgrade from v0.5 to v0.6 target/riscv: Correctly implement TSR trap Signed-off-by:

Currently riscv_cpu_local_irq_pending is used to find out pending interrupt and VS mode interrupts are being shifted to represent S mode interrupts in this function. So when the cause returned by this function is passed to riscv_cpu_do_interrupt to actually forward the interrupt, the VS mode forwarding check does not work as intended and interrupt is actually forwarded to hypervisor. This patch fixes this issue. Signed-off-by:

Add two GitLab jobs to build the OpenSBI firmware binaries. The first job builds a Docker image with the packages requisite to build OpenSBI, and stores this image in the GitLab registry. The second job pulls the image from the registry and builds the OpenSBI firmware binaries. The docker image is only rebuilt if the GitLab YAML or the Dockerfile is updated. The second job is only built when the roms/opensbi/ submodule is updated, when a git-ref starts with 'opensbi' or when the last commit contains 'OpenSBI'. The files generated are archived in the artifacts.zip file. With OpenSBI v0.6, it took 2 minutes 56 seconds to build the docker image, and 1 minute 24 seconds to generate the artifacts.zip with the firmware binaries (filesize: 111KiB).

Although the real world SiFive HiFive Unleashed board is a 64-bit hardware configuration, with QEMU it is possible to test 32-bit configuration with the same hardware features. This updates the roms Makefile to add the build rules for creating the 32-bit OpenSBI firmware image for sifive_u machine. A pre-built OpenSBI v0.6 image has been added as the default bios for 32-bit sifive_u machine. Signed-off-by:

The bochs-display mmio bar has some sub-regions with the actual hardware registers. What happens when the guest access something outside those regions depends on the archirecture. On x86 those reads succeed (and return 0xff I think). On risc-v qemu aborts. This patch adds handlers for the parent region, to make the wanted behavior explicit and to make things consistent across architectures. v2: - use existing unassigned_io_ops. - also cover stdvga.

Currently the internal float range of the mixing engine is [-.5f, .5f]. PulseAudio, SDL2 and libasound use a [-1.f, 1.f] range. This means with float samples the audio playback volume is 6dB too low and audio recording signals will be clipped in most cases. To avoid another scaling factor in the conv_natural_float_* and clip_natural_float_* functions with FLOAT_MIXENG defined this patch changes the mixing engine float range to [-1.f, 1.f].

This patch will reduce the downtime of VM for the initial process, Previously, we copied all these memory in preparing stage of COLO while we need to stop VM, which is a time-consuming process.

Currently, if the bytes_dirty_period is more than the 50% of bytes_xfer_period, we start or increase throttling. If we make this percentage higher, then we can tolerate higher dirty rate during migration, which means less impact on guest. The side effect of higher percentage is longer migration time. We can make this parameter configurable to switch between mig- ration time first or guest performance first. The default value is 50 and valid range is 1 to 100. Signed-off-by:

At the moment if the end-user does not specify the gic-version along with KVM acceleration, v2 is set by default. However most of the systems now have GICv3 and sometimes they do not support GICv2 compatibility. This patch keeps the default v2 selection in all cases except in the KVM accelerated mode when either - the host does not support GICv2 in-kernel emulation or - number of VCPUS exceeds 8. Those cases did not work anyway so we do not break any compatibility. Now we get v3 selected in such a case. Signed-off-by:

Restructure the finalize_gic_version with switch cases and clearly separate the following cases: - KVM mode / in-kernel irqchip - KVM mode / userspace irqchip - TCG mode In KVM mode / in-kernel irqchip , we explictly check whether the chosen version is supported by the host. If the end-user explicitly sets v2/v3 and this is not supported by the host, then the user gets an explicit error message. Note that for old kernels where the CREATE_DEVICE ioctl doesn't exist then we will now fail if the user specifically asked for gicv2, where previously we (probably) would have succeeded. In KVM mode / userspace irqchip we immediatly output an error in case the end-user explicitly selected v3. Also we warn the end-user about the unexpected usage of gic-version=host in that case as only userspace GICv2 is supported. Signed-off-by:

Convert kvm_arm_vgic_probe() so that it returns a bitmap of supported in-kernel emulation VGIC versions instead of the max version: at the moment values can be v2 and v3. This allows to expose the case where the host GICv3 also supports GICv2 emulation. This will be useful to choose the default version in KVM accelerated mode. Signed-off-by:

Let's move the code which freezes which gic-version to be applied in a dedicated function. We also now set by default the VIRT_GIC_VERSION_NO_SET. This eventually turns into the legacy v2 choice in the finalize() function. Signed-off-by:

Allwinner System-on-Chips usually contain a Real Time Clock (RTC) for non-volatile system date and time keeping. This commit adds a generic Allwinner RTC device that supports the RTC devices found in Allwinner SoC family sun4i (A10), sun7i (A20) and sun6i and newer (A31, H2+, H3, etc). The following RTC functionality and features are implemented: * Year-Month-Day read/write * Hour-Minute-Second read/write * General Purpose storage The following boards are extended with the RTC device: * Cubieboard (hw/arm/cubieboard.c) * Orange Pi PC (hw/arm/orangepi.c) Signed-off-by:

A real Allwinner H3 SoC contains a Boot ROM which is the first code that runs right after the SoC is powered on. The Boot ROM is responsible for loading user code (e.g. a bootloader) from any of the supported external devices and writing the downloaded code to internal SRAM. After loading the SoC begins executing the code written to SRAM. This commits adds emulation of the Boot ROM firmware setup functionality by loading user code from SD card in the A1 SRAM. While the A1 SRAM is 64KiB, we limit the size to 32KiB because the real H3 Boot ROM also rejects sizes larger than 32KiB. For reference, this behaviour is documented by the Linux Sunxi project wiki at: https://linux-sunxi.org/BROM#U-Boot_SPL_limitations Signed-off-by:
