      PPC: BookE: Make FIT/WDT timers at best millisecond grained · 84dc96e1
      由 Alexander Graf 提交于 
      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.

      PPC: Make BookE FIT/WDT timers more lazy · 455df3f3
      由 Alexander Graf 提交于 
      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.

      pc very last minute fixes for 1.7

This has a fix for a crasher bug with pci bridges,
boot failure fix for s390 on 32 bit hosts,
and fixes build for hosts with old glib.

There's also a fix for --iasl configure flag - it can be used
to work around broken iasl on some systems either
by using a non-standard iasl or by disabling it.

I've also reverted a e1000/rtl mac programming change
that seems slightly wrong and too risky for 1.8.

      qdev-properties-system.c: Allow vlan or netdev for -device, not both · 30c367ed
      由 Vlad Yasevich 提交于 
      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.

That patch treates the above command line options as invalid and
generates an error at start-up.

      mips jazz: do not raise data bus exception when accessing invalid addresses · b6a06e72
      由 Hervé Poussineau 提交于 
      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.

      target-i386: yield to another VCPU on PAUSE · b5fc314b
      由 Paolo Bonzini 提交于 
      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".
