(XII) Change Log
================
Here seems missed the changelog from RFCv5 -> RFCv6?
RFC V4 -> RFC V5:
-----------------
1. Dropped "[PATCH RFC V4 19/33] target/arm: Force ARM vCPU *present* status ACPI
*persistent*"
- Seperated the architecture agnostic ACPI changes required to support vCPU
Hotplug
Link:
https://lore.kernel.org/qemu-devel/[email protected]/#t
2. Dropped "[PATCH RFC V4 02/33] cpu-common: Add common CPU utility for possible
vCPUs"
- Dropped qemu{present,enabled}_cpu() APIs. Commented by Gavin (Redhat),
Miguel(Oracle), Igor(Redhat)
3. Added "Reviewed-by: Miguel Luis <[email protected]>" to [PATCH RFC V4
01/33]
3. Dropped the `CPUState::disabled` flag and introduced
`GICv3State::num_smp_cpus` flag
- All `GICv3CPUState' between [num_smp_cpus,num_cpus) are marked as
'inaccessible` during gicv3_common_realize()
- qemu_enabled_cpu() not required - removed!
- removed usage of `CPUState::disabled` from virt.c and hw/cpu64.c
4. Removed virt_cpu_properties() and introduced property `mp-affinity` get
accessor
5. Dropped "[PATCH RFC V4 12/33] arm/virt: Create GED device before *disabled* vCPU
Objects are destroyed"
[...]
It maybe known issue, but there are a bunch of failing qtests, listed as below.
