[RFC PATCH v0.1 00/25] ACPI/arm64: add support for virtual cpuhotplug

by James Morse

Hello! v0.1? Yeah, this is v0 from gitlab, rebased onto v6.0-rc3. This series has only been lightly tested.... --- Hello! This series adds what looks like cpuhotplug support to arm64 for use in virtual machines. It does this by moving the cpu_register() calls for architectures that support ACPI out of the arch code by using GENERIC_CPU_DEVICES, then into the ACPI processor driver. The kubernetes folk really want to be able to add CPUs to an existing VM, in exactly the same way they do on x86. The use-case is pre-booting guests with one CPU, then adding the number that were actually needed when the workload is provisioned. Wait? Doesn't arm64 support cpuhotplug already!? In the arm world, cpuhotplug gets used to mean removing the power from a CPU. The CPU is offline, and remains present. For x86, and ACPI, cpuhotplug has the additional step of physically removing the CPU, so that it isn't present anymore. Arm64 doesn't support this, and can't support it: CPUs are really a slice of the SoC, and there is not enough information in the existing ACPI tables to describe which bits of the slice also got removed. Without a reference machine adding this support to the spec is a wild goose chase. Critically: everything described in the firmware tables must remain present. For a virtual machine this is easy as all the other bits of 'virtual SoC' are emulated, so they can (and do) remain present when a vCPU is 'removed'. On a system that supports cpuhotplug the MADT has to describe every possible CPU at boot. Under KVM, the vGIC needs to know about every possible vCPU before the guest is started. With these constraints, virtual-cpuhotplug is really just a hypervisor/firmware policy about which CPUs can be brought online. This series adds support for virtual-cpuhotplug as exactly that: firmware policy. This may even work on a physical machine too; for a guest the part of firmware is played by the VMM. (typically Qemu). PSCI support is modified to return 'DENIED' if the CPU can't be brought online/enabled yet. The CPU object's _STA method's enabled bit is used to indicate firmware's current disposition. If the CPU has its enabled bit clear, it will not be registered with sysfs, and attempts to bring it online will fail. The notifications that _STA has changed its value then work in the same way, and firmware can cause the CPU to be registered some time later, allowing it to be brought online. This creates something that looks like cpuhotplug to user-space, as the sysfs files appear and disappear, and the udev notifications look the same. One notable difference is the CPU present mask, which is exposed via sysfs. Because the CPUs remain present throughout, they can still be seen in that mask. This value does get used by webbrowsers to estimate the number of CPUs as the CPU online mask is constantly changed on mobile phones. Linux is tolerant of PSCI returning errors, as its always been allowed to do that. To avoid confusing OS that can't tolerate this, we'd need an additional bit in the MADT GICC flags. This series copies ACPI_MADT_ONLINE_CAPABLE, which appears to be for this purpose, but calls it ACPI_MADT_GICC_CPU_CAPABLE as it has a different bit position in the GICC. I assume all x86 firmware vendors set the ENABLED bit in the CPU object's _STA method. This code is unconditionally enabled for all ACPI architectures. If there are problems with firmware tables on some devices, the CPUs will already be online by the time the acpi_processor_make_enabled() is called. A mismatch here causes a firmware-bug message and kernel taint. This should only affect people with broken firmware who also boot with maxcpus=1, and bring CPUs online later. I had a go at switching the remaining architectures over to GENERIC_CPU_DEVICES, so that the Kconfig symbol can be removed, but I got stuck with powerpc and s390. Thanks, James Morse (22): ACPI: Move ACPI_HOTPLUG_CPU to be enabled per architecture drivers: base: Use present CPUs in GENERIC_CPU_DEVICES drivers: base: Allow parts of GENERIC_CPU_DEVICES to be overridden drivers: base: Move node_dev_init() before cpu_dev_init() arm64: setup: Switch over to GENERIC_CPU_DEVICES using arch_register_cpu() ia64/topology: Switch over to GENERIC_CPU_DEVICES x86/topology: Switch over to GENERIC_CPU_DEVICES LoongArch: Switch over to GENERIC_CPU_DEVICES ACPI: processor: Register all CPUs from acpi_processor_get_info() ACPI: Rename ACPI_HOTPLUG_CPU to include 'present' ACPI: Rename acpi_processor_hotadd_init and remove pre-processor guards ACPI: Check _STA present bit before making CPUs not present ACPI: Warn when the present bit changes but the feature is not enabled drivers: base: Implement weak arch_unregister_cpu() LoongArch: Use the __weak version of arch_unregister_cpu() arm64: acpi: Move get_cpu_for_acpi_id() to a header ACPICA: Add new MADT GICC flags fields [code first?] arm64, irqchip/gic-v3, ACPI: Move MADT GICC enabled check into a helper irqchip/gic-v3: Don't return errors from gic_acpi_match_gicc() irqchip/gic-v3: Add support for ACPI's disabled but 'online capable' CPUs ACPI: add support to register CPUs based on the _STA enabled bit arm64: document virtual CPU hotplug's expectations Jean-Philippe Brucker (3): arm64: psci: Ignore DENIED CPUs KVM: arm64: Pass hypercalls to userspace KVM: arm64: Pass PSCI calls to userspace Documentation/arm64/cpu-hotplug.rst | 79 ++++++++++++++++++ Documentation/arm64/index.rst | 1 + Documentation/virt/kvm/api.rst | 31 ++++++- Documentation/virt/kvm/arm/hypercalls.rst | 1 + arch/arm64/Kconfig | 1 + arch/arm64/include/asm/acpi.h | 11 +++ arch/arm64/include/asm/cpu.h | 1 - arch/arm64/include/asm/kvm_host.h | 2 + arch/arm64/kernel/acpi_numa.c | 11 --- arch/arm64/kernel/psci.c | 2 +- arch/arm64/kernel/setup.c | 13 +-- arch/arm64/kernel/smp.c | 5 +- arch/arm64/kvm/arm.c | 15 +++- arch/arm64/kvm/hypercalls.c | 28 ++++++- arch/arm64/kvm/psci.c | 13 +++ arch/ia64/Kconfig | 2 + arch/ia64/include/asm/acpi.h | 2 +- arch/ia64/include/asm/cpu.h | 11 --- arch/ia64/kernel/acpi.c | 6 +- arch/ia64/kernel/setup.c | 2 +- arch/ia64/kernel/topology.c | 35 ++------ arch/loongarch/Kconfig | 2 + arch/loongarch/kernel/topology.c | 31 +------ arch/x86/Kconfig | 2 + arch/x86/include/asm/cpu.h | 6 -- arch/x86/kernel/acpi/boot.c | 4 +- arch/x86/kernel/topology.c | 19 +---- drivers/acpi/Kconfig | 5 +- drivers/acpi/acpi_processor.c | 99 ++++++++++++++++------- drivers/acpi/processor_core.c | 2 +- drivers/base/cpu.c | 21 +++-- drivers/base/init.c | 2 +- drivers/firmware/psci/psci.c | 2 + drivers/irqchip/irq-gic-v3.c | 38 +++++---- include/acpi/actbl2.h | 1 + include/kvm/arm_hypercalls.h | 1 + include/kvm/arm_psci.h | 4 + include/linux/acpi.h | 10 ++- include/linux/cpu.h | 6 ++ include/uapi/linux/kvm.h | 2 + 40 files changed, 339 insertions(+), 190 deletions(-) create mode 100644 Documentation/arm64/cpu-hotplug.rst -- 2.30.2

Linaro OP-TEE Contributions (LOC) monthly meeting

by Jens Wiklander

Hi, We don't have any topics for the meeting today, so let's cancel it. The time slot we've allocated for this meeting is either bad or worse for me so I'd like to try and find a new time slot. Please use the doodle link [1] below to record your preferences. The doodle poll is public so feel free to email me directly instead in case you're more comfortable with that. This is my first time creating a doodle poll, so apologies if I've made a mess of it. As noted in the poll we're looking for a day and time in the fourth week of the month. We're using the CET time zone as many of us are in the time zone. If you can't find any time that works for you please send me a mail with more suitable times and I'll try to work out something. Let's give this a week or so to possibly settle on a new time slot. [1] https://doodle.com/meeting/participate/id/dJqR4Eyb Thanks, Jens

ARM64 virt CPU HP - plan

by Lorenzo Pieralisi

Hi all, in the meeting held today we decided to go ahead as follows in relation to ARM64 virt CPU hotplug patches and QEmu changes: - James requires QEmu changes to test his branch[1] - Huawei (Salil) agreed to upgrade the QEmu patches to the latest ACPI specs (and James' code [1]) - QEmu updates will be given with a branch/link in reply to this email thread so that James can complete [1] testing against them - Any testing, bug report, communication will take place through this mailing list before public posting on a kernel ML, so please keep an eye on this thread if you'd like to collaborate/help - It would be good to get some feedback from containers/kubernetes developers on the full software stack - after all we are making these changes to enable the ecosystem Please chime in if I forgot something or reach out, all comments are welcome.
