Igor Mammedov 73c520b088 memory: reintroduce BQL-free fine-grained PIO/MMIO ... This patch brings back Jan's idea [1] of BQL-free IO access This will let us make access to ACPI PM/HPET timers cheaper, and prevent BQL contention in case of workload that heavily uses the timers with a lot of vCPUs. 1) 196ea13104 (memory: Add global-locking property to memory regions) ... de7ea885c5 (kvm: Switch to unlocked MMIO) Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Peter Xu <peterx@redhat.com> Link: https://lore.kernel.org/r/20250814160600.2327672-2-imammedo@redhat.com Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		1 week ago
