Make Big QEMU Lock naming consistent
|
expand
|
The Big QEMU Lock ("BQL") has two other names: "iothread lock" and "QEMU global mutex". The term "iothread lock" is easily confused with the unrelated --object iothread (iothread.c). This series updates the code and documentation to consistently use "BQL". This makes the code easier to understand. Stefan Hajnoczi (6): system/cpus: rename qemu_mutex_lock_iothread() to qemu_bql_lock() qemu/main-loop: rename QEMU_IOTHREAD_LOCK_GUARD to QEMU_BQL_LOCK_GUARD qemu/main-loop: rename qemu_cond_wait_iothread() to qemu_cond_wait_bql() system/cpus: rename qemu_global_mutex to qemu_bql Replace "iothread lock" with "BQL" in comments Rename "QEMU global mutex" to "BQL" in comments and docs docs/devel/multi-thread-tcg.rst | 7 +- docs/devel/qapi-code-gen.rst | 2 +- docs/devel/replay.rst | 2 +- docs/devel/reset.rst | 2 +- docs/devel/multiple-iothreads.txt | 16 ++-- hw/display/qxl.h | 2 +- include/block/aio-wait.h | 2 +- include/block/blockjob.h | 6 +- include/exec/cpu-common.h | 2 +- include/exec/memory.h | 4 +- include/exec/ramblock.h | 2 +- include/io/task.h | 2 +- include/migration/register.h | 8 +- include/qemu/coroutine-core.h | 2 +- include/qemu/coroutine.h | 2 +- include/qemu/main-loop.h | 54 ++++++------ target/arm/internals.h | 4 +- accel/accel-blocker.c | 10 +-- accel/dummy-cpus.c | 8 +- accel/hvf/hvf-accel-ops.c | 4 +- accel/kvm/kvm-accel-ops.c | 4 +- accel/kvm/kvm-all.c | 22 ++--- accel/tcg/cpu-exec.c | 26 +++--- accel/tcg/cputlb.c | 20 ++--- accel/tcg/tcg-accel-ops-icount.c | 6 +- accel/tcg/tcg-accel-ops-mttcg.c | 12 +-- accel/tcg/tcg-accel-ops-rr.c | 18 ++-- accel/tcg/tcg-accel-ops.c | 2 +- accel/tcg/translate-all.c | 2 +- cpu-common.c | 4 +- dump/dump.c | 4 +- hw/block/dataplane/virtio-blk.c | 8 +- hw/block/virtio-blk.c | 2 +- hw/core/cpu-common.c | 6 +- hw/display/virtio-gpu.c | 2 +- hw/i386/intel_iommu.c | 6 +- hw/i386/kvm/xen_evtchn.c | 30 +++---- hw/i386/kvm/xen_gnttab.c | 2 +- hw/i386/kvm/xen_overlay.c | 2 +- hw/i386/kvm/xen_xenstore.c | 2 +- hw/intc/arm_gicv3_cpuif.c | 2 +- hw/intc/s390_flic.c | 18 ++-- hw/mips/mips_int.c | 2 +- hw/misc/edu.c | 4 +- hw/misc/imx6_src.c | 2 +- hw/misc/imx7_src.c | 2 +- hw/net/xen_nic.c | 8 +- hw/ppc/pegasos2.c | 2 +- hw/ppc/ppc.c | 6 +- hw/ppc/spapr.c | 2 +- hw/ppc/spapr_events.c | 2 +- hw/ppc/spapr_rng.c | 4 +- hw/ppc/spapr_softmmu.c | 4 +- hw/remote/mpqemu-link.c | 14 ++-- hw/remote/vfio-user-obj.c | 2 +- hw/s390x/s390-skeys.c | 2 +- hw/scsi/virtio-scsi-dataplane.c | 6 +- migration/block-dirty-bitmap.c | 14 ++-- migration/block.c | 40 ++++----- migration/colo.c | 62 +++++++------- migration/dirtyrate.c | 12 +-- migration/migration.c | 54 ++++++------ migration/ram.c | 16 ++-- net/tap.c | 2 +- replay/replay-internal.c | 2 +- semihosting/console.c | 8 +- stubs/iothread-lock.c | 6 +- system/cpu-throttle.c | 6 +- system/cpus.c | 52 ++++++------ system/dirtylimit.c | 4 +- system/memory.c | 2 +- system/physmem.c | 14 ++-- system/runstate.c | 2 +- system/watchpoint.c | 4 +- target/arm/arm-powerctl.c | 14 ++-- target/arm/helper.c | 6 +- target/arm/hvf/hvf.c | 8 +- target/arm/kvm.c | 4 +- target/arm/kvm64.c | 4 +- target/arm/ptw.c | 6 +- target/arm/tcg/helper-a64.c | 8 +- target/arm/tcg/m_helper.c | 6 +- target/arm/tcg/op_helper.c | 24 +++--- target/arm/tcg/psci.c | 2 +- target/hppa/int_helper.c | 8 +- target/i386/hvf/hvf.c | 6 +- target/i386/kvm/hyperv.c | 4 +- target/i386/kvm/kvm.c | 28 +++---- target/i386/kvm/xen-emu.c | 16 ++-- target/i386/nvmm/nvmm-accel-ops.c | 6 +- target/i386/nvmm/nvmm-all.c | 20 ++--- target/i386/tcg/sysemu/fpu_helper.c | 6 +- target/i386/tcg/sysemu/misc_helper.c | 4 +- target/i386/whpx/whpx-accel-ops.c | 6 +- target/i386/whpx/whpx-all.c | 24 +++--- target/loongarch/csr_helper.c | 4 +- target/mips/kvm.c | 4 +- target/mips/tcg/sysemu/cp0_helper.c | 4 +- target/openrisc/sys_helper.c | 16 ++-- target/ppc/excp_helper.c | 14 ++-- target/ppc/helper_regs.c | 2 +- target/ppc/kvm.c | 4 +- target/ppc/misc_helper.c | 8 +- target/ppc/timebase_helper.c | 8 +- target/riscv/cpu_helper.c | 4 +- target/s390x/kvm/kvm.c | 4 +- target/s390x/tcg/misc_helper.c | 118 +++++++++++++-------------- target/sparc/int32_helper.c | 2 +- target/sparc/int64_helper.c | 6 +- target/sparc/win_helper.c | 20 ++--- target/xtensa/exc_helper.c | 8 +- ui/spice-core.c | 6 +- util/async.c | 2 +- util/main-loop.c | 8 +- util/rcu.c | 16 ++-- audio/coreaudio.m | 8 +- memory_ldst.c.inc | 18 ++-- target/i386/hvf/README.md | 2 +- ui/cocoa.m | 56 ++++++------- 119 files changed, 627 insertions(+), 628 deletions(-)
