2024-05-16plugins: conditional callbacksPierrick Bouvier2-0/+84
Extend plugins API to support callback called with a given criteria (evaluated inline). Added functions: - qemu_plugin_register_vcpu_tb_exec_cond_cb - qemu_plugin_register_vcpu_insn_exec_cond_cb They expect as parameter a condition, a qemu_plugin_u64_t (op1) and an immediate (op2). Callback is called if op1 |cond| op2 is true.

Move it to lockable.h, with only a small adjustment to coroutine.h (which has a tricky co-dependency with lockable.h due to defining CoMutex *and* using QemuLockable as a part of the CoQueue API).

2024-05-03bitmap: Use g_try_new0/g_new0/g_renewPaolo Bonzini1-11/+8
Avoids an explicit use of sizeof(). The GLib allocation macros ensure that the multiplication by the size of the element uses the right type and does not overflow. While at it, change bitmap_new() to use g_new0 directly. Its current impl of calling bitmap_try_new() followed by a plain abort() has worse diagnostics than g_new0, which uses g_error to report the actual allocation size that failed.

2024-03-18mirror: Don't call job_pause_point() under graph lockKevin Wolf1-1/+1
Calling job_pause_point() while holding the graph reader lock potentially results in a deadlock: bdrv_graph_wrlock() first drains everything, including the mirror job, which pauses it. The job is only unpaused at the end of the drain section, which is when the graph writer lock has been successfully taken. However, if the job happens to be paused at a pause point where it still holds the reader lock, the writer lock can't be taken as long as the job is still paused. Mark job_pause_point() as GRAPH_UNLOCKED and fix mirror accordingly.

2024-03-06plugins: remove non per_vcpu inline operation from APIPierrick Bouvier1-53/+5
Now we have a thread-safe equivalent of inline operation, and that all plugins were changed to use it, there is no point to keep the old API. In more, it will help when we implement more functionality (conditional callbacks), as we can assume that we operate on a scoreboard. API version bump was already done as part of this series.

2024-03-06plugins: add inline operation per vcpuPierrick Bouvier2-1/+51
Extends API with three new functions: qemu_plugin_register_vcpu_{tb, insn, mem}_exec_inline_per_vcpu(). Those functions takes a qemu_plugin_u64 as input. This allows to have a thread-safe and type-safe version of inline operations.

2024-03-06plugins: define qemu_plugin_u64Pierrick Bouvier1-0/+52
Additionally to the scoreboard, we define a qemu_plugin_u64, which is a simple struct holding a pointer to a scoreboard, and a given offset. This allows to have a scoreboard containing structs, without having to bring offset to operate on a specific field. Since most of the plugins are simply collecting a sum of per-cpu values, qemu_plugin_u64 directly support this operation as well. All inline operations defined later will use a qemu_plugin_u64 as input. New functions: - qemu_plugin_u64_add - qemu_plugin_u64_get - qemu_plugin_u64_set - qemu_plugin_u64_sum New macros: - qemu_plugin_scoreboard_u64 - qemu_plugin_scoreboard_u64_in_struct Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Pierrick Bouvier <pierrick.bouvier@linaro.org> Message-Id: <20240304130036.124418-3-pierrick.bouvier@linaro.org> Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Message-Id: <20240305121005.3528075-16-alex.bennee@linaro.org>
2024-03-06plugins: scoreboard APIPierrick Bouvier2-0/+37
We introduce a cpu local storage, automatically managed (and extended) by QEMU itself. Plugin allocate a scoreboard, and don't have to deal with how many cpus are launched. This API will be used by new inline functions but callbacks can benefit from this as well. This way, they can operate without a global lock for simple operations. At any point during execution, any scoreboard will be dimensioned with at least qemu_plugin_num_vcpus entries.
