2020-12-10vl: start VM via qmp_contPaolo Bonzini1-1/+2
Complement the previous patch by starting the VM with a QMP command. The plan is that the user will be able to do the same, invoking two commands "finish-machine-init" and "cont" instead of "x-exit-preconfig".

2020-12-10migration, vl: start migration via qmp_migrate_incomingPaolo Bonzini1-4/+7
Make qemu_start_incoming_migration local to migration/migration.c. By using the runstate instead of a separate flag, vl need not do anything to setup deferred incoming migration. qmp_migrate_incoming also does not need the deferred_incoming flag anymore, because "-incoming PROTOCOL" will clear the "once" flag before the main loop starts. Therefore, later invocations of the migrate-incoming command will fail with the existing "The incoming migration has already been started" error message.

2020-12-10vl: initialize displays before preconfig loopPaolo Bonzini1-21/+36
Displays should be available before the monitor starts, so that it is possible to use the graphical console to interact with the monitor itself. This patch is quite ugly, but all this is temporary. The double call to qemu_init_displays will go away as soon we can unify machine initialization between the preconfig and "normal" flows, and so will the preconfig_exit_requested variable (that is only preconfig_requested remains).

2020-12-10qemu-option: restrict qemu_opts_set to merge-lists QemuOptsPaolo Bonzini1-12/+7
qemu_opts_set is used to create default network backends and to parse sugar options -kernel, -initrd, -append, -bios and -dtb. These are very different uses: I would *expect* a function named qemu_opts_set to set an option in a merge-lists QemuOptsList, such as -kernel, and possibly to set an option in a non-merge-lists QemuOptsList with non-NULL id, similar to -set. However, it wouldn't *work* to use qemu_opts_set for the latter because qemu_opts_set uses fail_if_exists==1. So, for non-merge-lists QemuOptsList and non-NULL id, the semantics of qemu_opts_set (fail if the (QemuOptsList, id) pair already exists) are debatable. On the other hand, I would not expect qemu_opts_set to create a non-merge-lists QemuOpts with a single option; which it does, though. For this case of non-merge-lists QemuOptsList and NULL id, qemu_opts_set hardly adds value over qemu_opts_parse. It does skip some parsing and unescaping, but that's not needed when creating default network backends. So qemu_opts_set has warty behavior for non-merge-lists QemuOptsList if id is non-NULL, and it's mostly pointless if id is NULL. My solution to keeping the API as simple as possible is to limit qemu_opts_set to merge-lists QemuOptsList. For them, it's useful (we don't want comma-unescaping for -kernel) *and* has sane semantics. Network backend creation is switched to qemu_opts_parse. qemu_opts_set is now only used on merge-lists QemuOptsList... except in the testcase, which is changed to use a merge-list QemuOptsList. With this change we can also remove the id parameter. With the parameter always NULL, we know that qemu_opts_create cannot fail and can pass &error_abort to it.

2020-12-10vl: preconfig and loadvm are mutually exclusivePaolo Bonzini1-1/+6
Just like -incoming. Later we will add support for "-incoming defer -preconfig", because there are cases (Xen, block layer) that want to look at RUNSTATE_INMIGRATE. -loadvm will remain mutually exclusive with preconfig; the plan is to just do loadvm in the monitor, since the user is already going to interact with it for preconfiguration.

2020-10-13softmmu/vl: Be less verbose about missing KVM when running the qtestsThomas Huth1-7/+12
Some of the qtests use "-accel kvm -accel tcg" to run real guest code. This causes some error messages when kvm is not available. We do not really care about these messages since the fallback to tcg is expected here. So let's silence them to avoid that they spoil the output of the tests. Unfortunately, we can not use the qtest_enabled() wrapper in this case, since the qtest accelerator itself is not initialized. Thus we have to test for the qtest_chrdev variable instead.

refactoring of cpus.c continues with cpu timer state extraction. cpu-timers: responsible for the softmmu cpu timers state, including cpu clocks and ticks. icount: counts the TCG instructions executed. As such it is specific to the TCG accelerator. Therefore, it is built only under CONFIG_TCG. One complication is due to qtest, which uses an icount field to warp time as part of qtest (qtest_clock_warp). In order to solve this problem, provide a separate counter for qtest.

2020-08-21trace: switch position of headers to what Meson requiresPaolo Bonzini1-1/+1
Meson doesn't enjoy the same flexibility we have with Make in choosing the include path. In particular the tracing headers are using $(build_root)/$(<D). In order to keep the include directives unchanged, the simplest solution is to generate headers with patterns like "trace/trace-audio.h" and place forwarding headers in the source tree such that for example "audio/trace.h" includes "trace/trace-audio.h". This patch is too ugly to be applied to the Makefiles now. It's only a way to separate the changes to the tracing header files from the Meson rewrite of the tracing logic.

2020-07-24Revert "tpm: Clean up error reporting in tpm_init_tpmdev()"Markus Armbruster1-1/+3
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.
