block: drain from main loop thread in bdrv_co_yield_to_drain() For simplicity, always run BlockDevOps .drained_begin/end/poll() callbacks in the main loop thread. This makes it easier to implement the callbacks and avoids extra locks. Move the function pointer declarations from the I/O Code section to the Global State section for BlockDevOps, BdrvChildClass, and BlockDriver. Narrow IO_OR_GS_CODE() to GLOBAL_STATE_CODE() where appropriate. The test-bdrv-drain test case calls bdrv_drain() from an IOThread. This is now only allowed from coroutine context, so update the test case to run in a coroutine.

util/defer-call: move defer_call() to util/ The networking subsystem may wish to use defer_call(), so move the code to util/ where it can be reused. As a reminder of what defer_call() does: This API defers a function call within a defer_call_begin()/defer_call_end() section, allowing multiple calls to batch up. This is a performance optimization that is used in the block layer to submit several I/O requests at once instead of individually: defer_call_begin(); <-- start of section ... defer_call(my_func, my_obj); <-- deferred my_func(my_obj) call defer_call(my_func, my_obj); <-- another defer_call(my_func, my_obj); <-- another ... defer_call_end(); <-- end of section, my_func(my_obj) is called once Suggested-by: Ilya Maximets <i.maximets@ovn.org> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Message-ID: <20230913200045.1024233-3-stefanha@redhat.com> Reviewed-by: Michael S.

cpu-throttle: new module, extracted from cpus.c move the vcpu throttling functionality into its own module. This functionality is not specific to any accelerator, and it is used currently by migration to slow down guests to try to have migrations converge, and by the cocoa MacOS UI to throttle speed. cpu-throttle contains the controls to adjust and inspect throttle settings, start (set) and stop vcpu throttling, and the throttling function itself that is run periodically on vcpus to make them take a nap. Execution of the throttling function on all vcpus is triggered by a timer, registered at module initialization. No functionality change.

hw/dma: Let dma_buf_read() / dma_buf_write() propagate MemTxResult Since commit 292e13142d2, dma_buf_rw() returns a MemTxResult type. Do not discard it, return it to the caller. Pass the previously returned value (the QEMUSGList residual size, which was rarely used) as an optional argument. With this new API, SCSIRequest::residual might now be accessed via a pointer. Since the size_t type does not have the same size on 32 and 64-bit host architectures, convert it to a uint64_t, which is big enough to hold the residual size, and the type is constant on both 32/64-bit hosts. Update the few dma_buf_read() / dma_buf_write() callers to the new API.

dump: Allow directly outputting raw kdump format The flattened format (currently output by QEMU) is used by makedumpfile only when it is outputting a vmcore to a file which is not seekable. The flattened format functions essentially as a set of instructions of the form "seek to the given offset, then write the given bytes out". The flattened format can be reconstructed using makedumpfile -R, or makedumpfile-R.pl, but it is a slow process because it requires copying the entire vmcore. The flattened format can also be directly read by crash, but still, it requires a lengthy reassembly phase. To sum up, the flattened format is not an ideal one: it should only be used on files which are actually not seekable. This is the exact strategy which makedumpfile uses, as seen in the implementation of "write_buffer()" in makedumpfile [1]. However, QEMU has always used the flattened format. For compatibility it is best not to change the default output format without warning. So, add a flag to DumpState which changes the output to use the normal (i.e. raw) format. This flag will be added to the QMP and HMP commands in the next change.

hw/xen: select kernel mode for per-vCPU event channel upcall vector A guest which has configured the per-vCPU upcall vector may set the HVM_PARAM_CALLBACK_IRQ param to fairly much anything other than zero. For example, Linux v6.0+ after commit b1c3497e604 ("x86/xen: Add support for HVMOP_set_evtchn_upcall_vector") will just do this after setting the vector: /* Trick toolstack to think we are enlightened. */ if (!cpu) rc = xen_set_callback_via(1); That's explicitly setting the delivery to GSI#1, but it's supposed to be overridden by the per-vCPU vector setting. This mostly works in Qemu *except* for the logic to enable the in-kernel handling of event channels, which falsely determines that the kernel cannot accelerate GSI delivery in this case. Add a kvm_xen_has_vcpu_callback_vector() to report whether vCPU#0 has the vector set, and use that in xen_evtchn_set_callback_param() to enable the kernel acceleration features even when the param *appears* to be set to target a GSI. Preserve the Xen behaviour that when HVM_PARAM_CALLBACK_IRQ is set to *zero* the event channel delivery is disabled completely. (Which is what that bizarre guest behaviour is working round in the first place.)

rtc: Use time_t for passing and returning time offsets The functions qemu_get_timedate() and qemu_timedate_diff() take and return a time offset as an integer. Coverity points out that means that when an RTC device implementation holds an offset as a time_t, as the m48t59 does, the time_t will get truncated. (CID 1507157, 1517772). The functions work with time_t internally, so make them use that type in their APIs. Note that this won't help any Y2038 issues where either the device model itself is keeping the offset in a 32-bit integer, or where the hardware under emulation has Y2038 or other rollover problems. If we missed any cases of the former then hopefully Coverity will warn us about them since after this patch we'd be truncating a time_t in assignments from qemu_timedate_diff().)

sandbox: disable -sandbox if CONFIG_SECCOMP undefined If CONFIG_SECCOMP is undefined, the option 'elevatedprivileges' remains compiled. This would make libvirt set the corresponding capability and then trigger failure during guest startup. This patch moves the code regarding seccomp command line options to qemu-seccomp.c file and wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP. Because parse_sandbox() is moved into qemu-seccomp.c file, change seccomp_start() to static function.

include: Make headers more self-contained Back in 2016, we discussed[1] rules for headers, and these were generally liked: 1. Have a carefully curated header that's included everywhere first. We got that already thanks to Peter: osdep.h. 2. Headers should normally include everything they need beyond osdep.h. If exceptions are needed for some reason, they must be documented in the header. If all that's needed from a header is typedefs, put those into qemu/typedefs.h instead of including the header. 3. Cyclic inclusion is forbidden. This patch gets include/ closer to obeying 2. It's actually extracted from my "[RFC] Baby steps towards saner headers" series[2], which demonstrates a possible path towards checking 2 automatically. It passes the RFC test there.
