3 daysqapi: Move include/qapi/qmp/ to include/qobject/Daniel P. Berrangé1-1/+1
The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. Most of the headers there correspond to source files in qobject/. This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there. This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h: scripts/get_maintainer.pl now reports "QAPI" instead of "No maintainers found". Signed-off-by: Daniel P.

2024-12-26system/dirtylimit: Don't use migration_is_active()Avihai Horon1-2/+1
vcpu_dirty_rate_stat_collect() uses migration_is_active() to detect whether migration is running or not, in order to get the correct dirty rate period value. However, recently there has been an effort to simplify the migration status API and reduce it to a single migration_is_running() function. To accommodate this, and since the same functionality can be achieved with migration_is_running(), use it instead of migration_is_active().

Headers in include/sysemu/ are not only related to system *emulation*, they are also used by virtualization. Rename as system/ which is clearer. Files renamed manually then mechanical change using sed tool.

2024-03-11migration: export fewer optionsSteve Sistare1-1/+0
A small number of migration options are accessed by migration clients, but to see them clients must include all of options.h, which is mostly for migration core code. migrate_mode() in particular will be needed by multiple clients. Refactor the option declarations so clients can see the necessary few via misc.h, which already exports a portion of the client API.

2024-01-08system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()Stefan Hajnoczi1-2/+2
The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.
