Are the kernel changes planned for 6.14 ?
FYI, QEMU 10.0 hard freeze is scheduled for 2025-03-18 which is
approximately when 6.14-rc7 will be released.
Thanks,

has been received and stores it in a queue. These objects will later
be used to store event information for an AP configuration change
when the CHSC instruction is intercepted.

he handler in turn notifies the guest that its AP configuration
has changed. This allows the guest to immediately respond to AP
configuration changes rather than relying on polling or some other
inefficient mechanism for detecting config changes.
