This patch adds firmware to the machine options. -bios <file> becomes a shortcut for -machine firmware=<file>. Advantage is that the firmware can be specified via config file as -machine is parsed using QemuOpts and it is also possible to use different defaults for different machine types (via QEMUMachine->default_machine_opts).

For "none" sync mode in "absolute-paths" mode, the current image should be used as the backing file for the newly created image. The current behavior is: a) If the image to be mirrored has a backing file, use that (which is wrong, since the operations recorded by "none" are applied to the image itself, not to its backing file). b) If the image to be mirrored lacks a backing file, the target doesn't have one either (which is not really wrong, but not really right, either; "none" records a set of operations executed on the image file, therefore having no backing file to apply these operations on seems rather pointless). For a, this is clearly a bugfix. For b, it is still a bugfix, although it might break existing API - but since that case crashed qemu just three weeks ago (before 14526864), we can safely assume there is no such API relying on that case yet.

The default granularity for the FIT timer on 440 is on every 0x1000th transition of TB from 0 to 1. Translated that means 48828 times a second. Since interrupts are quite expensive for 440 and we don't really care about the accuracy of the FIT to that significance, let's force FIT and WDT to at best millisecond granularity. This basically restores behavior as it was in QEMU 1.6, where timers could only deal with millisecond granularities at all. This patch greatly improves performance with the 440 target and restores roughly the same performance level that QEMU 1.6 had for me.

Today we fire FIT and WDT timer events every time the respective bit position in TB flips from 0 -> 1. However, there is no need to do this if the end result would be that we're changing a TSR bit that is set to 1 to 1 again. No guest visible change would have occured. So whenever we see that the TSR bit to our timer is already set, don't even bother to update the timer that would potentially fire it off. However, we do need to make sure that we update our timer that notifies us of the TB flip when the respective TSR bit gets unset. In that case we do care about the flip and need to notify the guest again. So add a callback into our timer handlers when TSR bits get unset. This improves performance for me when the guest is busy processing things.

It is currently possible to specify things like: -device e1000,netdev=foo,vlan=1 With this usage, whichever argument was specified last (vlan or netdev) overwrites what was previousely set and results in a non-working configuration. Even worse, when used with multiqueue devices, it causes a segmentation fault on exit in qemu_free_net_client.

MIPS Jazz chipset doesn't seem to raise data bus exceptions on invalid accesses. However, there is no easy way to prevent them. Creating a big memory region for the whole address space doesn't prevent memory core to directly call unassigned_mem_read/write which in turn call cpu->do_unassigned_access, which (for MIPS CPU) raise an data bus exception.

After commit b1bbfe72 (aio / timers: On timer modification, qemu_notify or aio_notify, 2013-08-21) FreeBSD guests report a huge slowdown. The problem shows up as soon as FreeBSD turns out its periodic (~1 ms) tick, but the timers are only the trigger for a pre-existing problem. Before the offending patch, setting a timer did a timer_settime system call. After, setting the timer exits the event loop (which uses poll) and reenters it with a new deadline. This does not cause any slowdown; the difference is between one system call (timer_settime and a signal delivery (SIGALRM) before the patch, and two system calls afterwards (write to a pipe or eventfd + calling poll again when re-entering the event loop). Unfortunately, the exit/enter causes the main loop to grab the iothread lock, which in turns kicks the VCPU thread out of execution. This causes TCG to execute the next VCPU in its round-robin scheduling of VCPUS. When the second VCPU is mostly unused, FreeBSD runs a "pause" instruction in its idle loop which only burns cycles without any progress. As soon as the timer tick expires, the first VCPU runs the interrupt handler but very soon it sets it again---and QEMU then goes back doing nothing in the second VCPU. The fix is to make the pause instruction do "cpu_loop_exit".

This causes two slight backwards-incompatibilities between "-M pc-1.5" and 1.5's "-M pc": (1) a fw_cfg file is removed with this patch. This is only a problem if migration stops the virtual machine exactly during fw_cfg enumeration. (2) after migration, a VM created without an explicit "-device pvpanic" will stop reporting panics to management. The first problem only occurs if migration is done at a very, very early point (and I'm not sure it can happen in practice for reasonable-size VMs, since it will likely take more time to send the RAM to destination, than it will take for BIOS to scan fw_cfg). The second problem only occurs if the guest panics _and_ has a guest driver _and_ management knows to look at the crash event, so it is mostly theoretical at this point in time. Thus keep the code simple, and pretend it was never broken. Reviewed-by: NEric Blake <eblake@redhat.com> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Our rules.mak adds '-rR' to MAKEFLAGS to indicate that we will be explicitly specifying everything and not relying on any default variables or rules. However we were accidentally relying on the default ARFLAGS ("rv"). This went unnoticed because of a bug in GNU Make 3.82 and earlier which meant that adding -rR to MAKEFLAGS only affected submakes, not the currently running instance. Explicitly set ARFLAGS in config-host.mak, in the same way we handle CFLAGS and LDFLAGS; this will allow us to work with Make 4.0. Thanks to Paul Smith for analyzing this bug for us.

Upstream OpenBIOS now implements SBus probing in order to determine the contents of a physical bus slot, which is required to allow OpenBIOS to identify the framebuffer without help from the fw_cfg interface. SBus probing works by detecting the presence of an FCode program (effectively tokenised Forth) at the base address of each slot, and if present executes it so that it creates its own device node in the OpenBIOS device tree. The FCode ROM is generated as part of the OpenBIOS build and should generally be updated at the same time.

Commit 787aaf57 (target-i386: forward CPUID cache leaves when -cpu host is used, 2013-09-02) brings bits 31..26 of CPUID leaf 04h out of sync with the APIC IDs that QEMU reserves for each package. This number must come from "-smp" options rather than from the host CPUID. It also turns out that this unsyncing makes Windows Server 2012R2 fail to boot.

MIPS Jazz chipset doesn't seem to raise data bus exceptions on invalid accesses. However, there is no easy way to prevent them. Creating a big memory region for the whole address space doesn't prevent memory core to directly call unassigned_mem_read/write which in turn call cpu->do_unassigned_access, which (for MIPS CPU) raise an data bus exception. This fixes a MIPS Jazz regression introduced in c658b94f.

After commit b1bbfe72 (aio / timers: On timer modification, qemu_notify or aio_notify, 2013-08-21) FreeBSD guests report a huge slowdown. The problem shows up as soon as FreeBSD turns out its periodic (~1 ms) tick, but the timers are only the trigger for a pre-existing problem. Before the offending patch, setting a timer did a timer_settime system call. After, setting the timer exits the event loop (which uses poll) and reenters it with a new deadline. This does not cause any slowdown; the difference is between one system call (timer_settime and a signal delivery (SIGALRM) before the patch, and two system calls afterwards (write to a pipe or eventfd + calling poll again when re-entering the event loop). Unfortunately, the exit/enter causes the main loop to grab the iothread lock, which in turns kicks the VCPU thread out of execution. This causes TCG to execute the next VCPU in its round-robin scheduling of VCPUS. When the second VCPU is mostly unused, FreeBSD runs a "pause" instruction in its idle loop which only burns cycles without any progress. As soon as the timer tick expires, the first VCPU runs the interrupt handler but very soon it sets it again---and QEMU then goes back doing nothing in the second VCPU. The fix is to make the pause instruction do "cpu_loop_exit".

The buffer content might be read out more than once, currently we just repeatedly read the first data block, buffer offset is missing.
