It is more typical to provide the ';' by the caller of a macro than to embed it in the macro itself; this is because syntax highlight engines can get confused if a macro is called without a semicolon before the closing '}'.

For a couple of macros in pcnet.c, we have to provide a new scope to avoid compiler warnings about declarations in the middle of a switch statement that aren't in a sub-scope. But use of 'do { ... } while (0);' merely to provide that new scope is arcane overkill, compared to just using '{ ... }'.

Except for round-robin TCG, every other accelerator is using more or less the same code around qemu_wait_io_event_common. The exception is HAX, which also has to eat the dummy APC that is queued by qemu_cpu_kick_thread. We can add the SleepEx call to qemu_wait_io_event under "if (!tcg_enabled())", since that is the condition that is used in qemu_cpu_kick_thread, and unify the function for KVM, HAX, HVF and multi-threaded TCG. Single-threaded TCG code can also be simplified since it is only used in the round-robin, sleep-if-all-CPUs-idle case. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

This patch adds saving and restoring of the icount warp timers in the vmstate. It is needed because there timers affect the virtual clock value. Therefore determinism of the execution in icount record/replay mode depends on determinism of the timers.

x86_update_hflags reference env->efer which is updated in hax_get_msrs, so it has to be called after hax_get_msrs. This fix the bug that sometimes dump_state show 32 bits regs even in 64 bits mode.

scsi_write_same_complete() can retry the write if the request was unaligned. Make sure to release the AioContext when that code path is taken! This patch fixes a hang when QEMU terminates after an unaligned WRITE SAME request has been processed with dataplane. The hang occurs because iothread_stop_all() cannot acquire the AioContext lock that was leaked by the IOThread in scsi_write_same_complete(). Fixes: b9e413dd ("block: explicitly acquire aiocontext in aio callbacks that need it").

When --enable-debug is turned on, configure doesn't set -O level, and uses default compiler -O0 level, which is slow. Instead, use -Og if supported by the compiler (optimize debugging experience), or -O1 (keeps code somewhat debuggable and works around compiler bugs). Unfortunately, gcc has many false-positive maybe-uninitialized errors with Og and O1 (f27 gcc 7.2.1 20170915): /home/elmarco/src/qemu/hw/ipmi/isa_ipmi_kcs.c: In function ‘ipmi_kcs_ioport_read’: /home/elmarco/src/qemu/hw/ipmi/isa_ipmi_kcs.c:279:12: error: ‘ret’ may be used uninitialized in this function [-Werror=maybe-uninitialized] return ret; ^~~ cc1: all warnings being treated as errors make: *** [/home/elmarco/src/qemu/rules.mak:66: hw/ipmi/isa_ipmi_kcs.o] Error 1 make: *** Waiting for unfinished jobs.... /home/elmarco/src/qemu/hw/ide/ahci.c: In function ‘ahci_populate_sglist’: /home/elmarco/src/qemu/hw/ide/ahci.c:903:58: error: ‘tbl_entry_size’ may be used uninitialized in this function [-Werror=maybe-uninitialized] if ((off_idx == -1) || (off_pos < 0) || (off_pos > tbl_entry_size)) { ~~~~~~~~~^~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors make: *** [/home/elmarco/src/qemu/rules.mak:66: hw/ide/ahci.o] Error 1 /home/elmarco/src/qemu/hw/display/qxl.c: In function ‘qxl_add_memslot’: /home/elmarco/src/qemu/hw/display/qxl.c:1397:52: error: ‘pci_start’ may be used uninitialized in this function [-Werror=maybe-uninitialized] memslot.virt_end = virt_start + (guest_end - pci_start); ~~~~~~~~~~~~~^~~~~~~~~~~~ /home/elmarco/src/qemu/hw/display/qxl.c:1389:9: error: ‘pci_region’ may be used uninitialized in this function [-Werror=maybe-uninitialized] qxl_set_guest_bug(d, "%s: pci_region = %d", __func__, pci_region); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors There seems to be a long list of related bugs in upstream GCC, some of them are being fixed very recently: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=24639 For now, let's workaround it by using Wno-maybe-uninitialized (gcc-only).

When linking qemu-ga under some configuration (when gthread-2.0.pc doesn't have -pthread, as happening atm with meson build), you may have this linking issue: /usr/bin/ld: libqemuutil.a(qemu-thread-posix.o): undefined reference to symbol 'pthread_setname_np@@GLIBC_2.12' /usr/lib64/libpthread.so.0: error adding symbols: DSO missing from command line Make sure qemu-ga links with the pthread library, by adding correct flags to libs_qga. This is really a QEMU bug, because it's QEMU code that's using pthread functions, and so we must explicitly link against pthreads. The bug was just masked by the fact that often some pkg-config or another for one of our dependencies will add -pthread to the link line anyway.

It's a replacement of g_timeout_add[_seconds]() for chardevs. Chardevs now can have dedicated gcontext, we should always bind chardev tasks onto those gcontext rather than the default main context. Since there are quite a few of g_timeout_add[_seconds]() callers, a new function qemu_chr_timeout_add_ms() is introduced. One thing to mention is that, terminal3270 is still always running on main gcontext. However let's convert that as well since it's still part of chardev codes and in case one day we'll miss that when we move it out of main gcontext too. Also, convert all the timers from GSource tags into GSource pointers. Gsource tag IDs and g_source_remove()s can only work with default gcontext, while now these GSources can logically be attached to other contexts. So let's use explicit g_source_destroy() plus another g_source_unref() to remove a timer. Note: when in the timer handler, we don't need the g_source_destroy() any more since that'll be done automatically if the timer handler returns false (and that's what all the current handlers do). Yet another note: in pty_chr_rearm_timer() we take special care for ms=1000. This patch merged the two cases into one.

The idle task will be attached to main gcontext even if the chardev backend is running in another gcontext. Fix the only caller by extending the g_idle_add() logic into the more powerful g_source_attach(). It's basically g_idle_add_full() implementation, but with the chardev's gcontext passed in.

In commit 6bbb6c06 ("chardev: use per-dev context for io_add_watch_poll", 2017-09-22) all the chardev watches are converted to use per-chardev gcontext to support chardev to be run outside default main thread. However that's still missing one call from the frontend code. Touch that up.

Certain PMU-related MSRs are not supported for CPUs with PMU architecture below version 2. KVM rejects any access to them (see intel_is_valid_msr_idx routine in KVM), and QEMU fails on the following assertion: kvm_put_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed. QEMU also could fail if KVM exposes less fixed counters then 3. It could happen if host system run inside another hypervisor, which is tweaking PMU-related CPUID. To prevent possible fail, number of fixed counters now is obtained in the same way as number of GP counters.

Add the property to the device model, then parse it by calling blkconf_apply_backend_options(). In addition to blk_set_perm(), the called function also handles error options and wce. For error options we've already checked that the default values are used, for wce we don't have the option either so it is always the default (true). In other words there is no change of behavior in these regards.
