2020-09-16monitor: simplify functions for getting a dup'd fdset entryDaniel P. Berrangé1-6/+2
Currently code has to call monitor_fdset_get_fd, then dup the return fd, and then add the duplicate FD back into the fdset. This dance is overly verbose for the caller and introduces extra failure modes which can be avoided by folding all the logic into monitor_fdset_dup_fd_add and removing monitor_fdset_get_fd entirely.

2020-09-07stubs: Move qemu_fd_register stub to util/main-loop.cThomas Huth2-7/+0

2020-09-07stubs: Move qemu_timer_notify_cb() and remove qemu_notify_event() stubThomas Huth4-12/+9
When cross-compiling with MinGW, there are sometimes some weird linker errors like: ibqemuutil.a(util_main-loop.c.obj): In function `qemu_notify_event': /builds/huth/qemu/build/../util/main-loop.c:139: multiple definition of `qemu_notify_event' libqemuutil.a(stubs_notify-event.c.obj):/builds/huth/qemu/stubs/notify-event.c:5: first defined here collect2: error: ld returned 1 exit status /builds/huth/qemu/rules.mak:88: recipe for target 'tests/test-timed-average.exe' failed It seems like it works better when the qemu_timer_notify_cb() stub (which calls qemu_notify_event()) is in a separate file - then we can also even remove the qemu_notify_event() stub now. This patch is based on ideas from the patch "stubs: Remove qemu_notify_event()" by Philippe Mathieu-Daudé and the patch "cpu-timers, icount: new modules" from Claudio Fontana.

2020-08-21libqemuutil, qapi, trace: convert to mesonPaolo Bonzini2-56/+50
This shows how to do some "computations" in meson.build using its array and dictionary data structures, and also a basic usage of the sourceset module for conditional compilation. Notice the new "if have_system" part of util/meson.build, which fixes a bug in the old build system was buggy: util/dbus.c was built even for non-softmmu builds, but the dependency on -lgio was lost when the linking was done through libqemuutil.a. Because all of its users required gio otherwise, the bug was hidden. Meson instead propagates libqemuutil's dependencies down to its users, and shows the problem.

2020-07-24Revert "tpm: Clean up error reporting in tpm_init_tpmdev()"Markus Armbruster1-1/+2
This reverts commit d10e05f15d5c3dd5e5cc59c5dfff460d89d48580. We report some -tpmdev failures, but then continue as if all was fine. Reproducer: $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -chardev null,id=tpm0 -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0 qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: tpm chardev 'chrtpm' not found. qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: Could not cleanly shutdown the TPM: No such file or directory QEMU 5.0.90 monitor - type 'help' for more information (qemu) qemu-system-x86_64: -device tpm-tis,tpmdev=tpm0: Property 'tpm-tis.tpmdev' can't find value 'tpm0' $ echo $? 1 This is a regression caused by commit d10e05f15d "tpm: Clean up error reporting in tpm_init_tpmdev()". It's incomplete: be->create(opts) continues to use error_report(), and we don't set an error when it fails. I figure converting the create() methods to Error would make some sense, but I'm not sure it's worth the effort right now. Revert the broken commit instead, and add a comment to tpm_init_tpmdev(). Straightforward conflict in tpm.c resolved.

Follow linux-aio.o and stub out the block/io_uring.o APIs that will be missing when a binary is linked with obj-util-y but without block-util-y (e.g. vhost-user-gpu). For example, the stubs are necessary so that a binary using util/async.o from obj-util-y for qemu_bh_new() links successfully. In this case block/io_uring.o from block-util-y isn't needed and we can avoid dragging in the block layer by linking the stubs instead. The stub functions never get called.

2020-01-09semihosting: add qemu_semihosting_console_inc for SYS_READCKeith Packard1-0/+4
Provides a blocking call to read a character from the console using semihosting.chardev, if specified. This takes some careful command line options to use stdio successfully as the serial ports, monitor and semihost all want to use stdio. Here's a sample set of command line options which share stdio between semihost, monitor and serial ports: qemu \ -chardev stdio,mux=on,id=stdio0 \ -serial chardev:stdio0 \ -semihosting-config enable=on,chardev=stdio0 \ -mon chardev=stdio0,mode=readline This creates a chardev hooked to stdio and then connects all of the subsystems to it.

2019-10-14replay: add BH oneshot event for block layerPavel Dovgalyuk2-0/+10
Replay is capable of recording normal BH events, but sometimes there are single use callbacks scheduled with aio_bh_schedule_oneshot function. This patch enables recording and replaying such callbacks. Block layer uses these events for calling the completion function. Replaying these calls makes the execution deterministic.

2019-08-16sysemu: Split sysemu/runstate.h off sysemu/sysemu.hMarkus Armbruster3-3/+3
sysemu/sysemu.h is a rather unfocused dumping ground for stuff related to the system-emulator. Evidence: * It's included widely: in my "build everything" tree, changing sysemu/sysemu.h still triggers a recompile of some 1100 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h, down from 5400 due to the previous two commits). * It pulls in more than a dozen additional headers. Split stuff related to run state management into its own header sysemu/runstate.h. Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h also drops from 1100 to 850, and qapi/qapi-types-run-state.h from 4400 to 4200. Touching new sysemu/runstate.h recompiles some 500 objects. Since I'm touching MAINTAINERS to add sysemu/runstate.h anyway, also add qemu/main-loop.h.

2019-08-16Clean up inclusion of sysemu/sysemu.hMarkus Armbruster2-1/+1
In my "build everything" tree, changing sysemu/sysemu.h triggers a recompile of some 5400 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). Almost a third of its inclusions are actually superfluous. Delete them. Downgrade two more to qapi/qapi-types-run-state.h, and move one from char/serial.h to char/serial.c. hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and stubs/semihost.c define variables declared in sysemu/sysemu.h without including it. The compiler is cool with that, but include it anyway. This doesn't reduce actual use much, as it's still included into widely included headers. The next commit will tackle that.

We commonly want to print to the current monitor if we have one, else to stdout/stderr. For stderr, have error_printf(). For stdout, all we have is monitor_vfprintf(), which is rather unwieldy. We often print to stderr just because error_printf() is easier. New qemu_printf() and qemu_vprintf() do exactly what's needed. The next commits will put them to use.

2019-04-18monitor error: Make printf()-like functions return a valueMarkus Armbruster1-5/+8
printf() & friends return the number of characters written on success, negative value on error. monitor_printf(), monitor_vfprintf(), monitor_vprintf(), error_printf(), error_printf_unless_qmp(), error_vprintf(), and error_vprintf_unless_qmp() return void. Some of them carry a TODO comment asking for int instead. Improve them to return int like printf() does. This makes our use of monitor_printf() as fprintf_function slightly less dirty: the function cast no longer adds a return value that isn't there. It still changes a parameter's pointer type. That will be addressed in a future commit. monitor_vfprintf() always returns zero. Improve it to return the proper value.

2019-03-06exec: Change RAMBlockIterFunc definitionYury Kotov1-0/+15
Currently, qemu_ram_foreach_* calls RAMBlockIterFunc with many block-specific arguments. But often iter func needs RAMBlock*. This refactoring is needed for fast access to RAMBlock flags from qemu_ram_foreach_block's callback. The only way to achieve this now is to call qemu_ram_block_from_host (which also enumerates blocks). So, this patch reduces complexity of qemu_ram_foreach_block() -> cb() -> qemu_ram_block_from_host() from O(n^2) to O(n). Fix RAMBlockIterFunc definition and add some functions to read RAMBlock* fields witch were passed.
