Hyper-V direct tlb flush targets KVM on Hyper-V guest.
Enable direct TLB flush for its guests meaning that TLB
flush hypercalls are handled by Level 0 hypervisor (Hyper-V)
bypassing KVM in Level 1. Due to the different ABI for hypercall
parameters between Hyper-V and KVM, KVM

In current logic, if compress_threads_save_setup() returns -1 the whole

Two patches related to compress:
1. simplify the check since compress QEMUFile is not writable
2. handle compress setup failure gracefully
Wei Yang (2):
migration/compress: compress QEMUFile is not writable
migration/compress: disable compress if failed to setup

We open a file with empty_ops for compress QEMUFile, which means this is
not writable.

riscv_cpu_tlb_fill() uses the `size` parameter to check PMP violation
using pmp_hart_has_privs().
However, if the size is unknown (=0), the ending address will be
`addr - 1` as it is `addr + size - 1` in `pmp_hart_has_privs()`.
This always causes a false PMP violation on the starting address of

multifd_send_fill_packet() prepares meta data for following pages to
transfer. It would be more proper to fill pages->allocated instead of
static max value, especially we want to support flexible packet size.

When we found an available channel in multifd_send_pages(), its

It is not necessary to do this twice.

RCU_READ_LOCK_GUARD() takes the rcu_read_lock and then uses glib's
g_auto infrastructure (and thus whatever the compiler's hooks are) to
release it on all exits of the block.
WITH_RCU_READ_LOCK_GUARD() is similar but is used as a wrapper for the
lock, i.e.:

During migration, a tmp page is allocated so that we could place a whole
host page during postcopy.
Currently the page is allocated during load stage, this is a little bit
late. And more important, if we failed to allocate it, the error is not
checked properly. Even it is NULL,

In normal precopy we can't do reconnection recovery - but we also
don't need to, since you can just rerun migration.
At the moment if the 'return-path' capability is on, we use

Hi,
I want to add some I2C based temperature sensors to the -M Q35 machine. I
want to update the ACPI tables to add this device information. How can I go
about doing this?
Thanks,
Gautam.
