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,

Hi,
The LOC meeting this month is in the middle of the holidays. Let's
cancel it since we don't have any urgent topics.

Dear members,
The next Linaro Connect will be held in London, United Kingdom, from
Wednesday 26 till Friday 28 April 2023 at the Park Plaza Riverbank.
[58]https://www.linaro.org/connect
Linaro Member Companies will be eligible for one or more free passes
depending on your membership tier and will also get a discounted rate
for general tickets. You will soon receive communication from our
Events team with your Connect conference registration code via the
usual channels.
As discussed during our face-to-face partner meeting last month, we are
pleased to confirm that we will hold the next Linaro Partner Meeting
the same week as Connect. LPM will start on Monday April 24th at 1pm
and will end on Tuesday evening. It will be open to all Core,
Club, Group and Project members.
Connect will then follow on Wednesday through Friday.
I am sending a calendar invite for LPM as a placeholder for your
convenience, more details will follow in January.
All attendees can start booking a room at the Park Plaza Riverbank
using the Linaro group code [LINC23]. Please contact
[59]connect(a)linaro.org if you have any issue with this code. In the
booking page make sure you select the "Promotional Code" (and enter
LINC23) in the "selected rate" field.
