04920fc0fa loader: store FW CFG ROM files in RAM
ROM files that are put in FW CFG are copied to guest ram, by BIOS, but
they are not backed by RAM so they don't get migrated.

Each time we change two bytes in such a ROM this breaks cross-version
migration: since we can migrate after BIOS has read the first byte but
before it has read the second one, getting an inconsistent state.

Future-proof this by creating, for each such ROM,
an MR serving as the backing store.
This MR is never mapped into guest memory, but it's registered
as RAM so it's migrated with the guest.

Naturally, this only helps for -M 1.7 and up, older machine types
will still have the cross-version migration bug.
Luckily the race window for the problem to trigger is very small,
which is also likely why we didn't notice the cross-version
migration bug in testing yet.

4a44d85e28 Convert stderr message calling error_get_pretty() to error_report()
Convert stderr messages calling error_get_pretty()
to error_report().

Timestamp is prepended by -msg timstamp option with it.

Per Markus's comment below, A conversion from fprintf() to
error_report() is always an improvement, regardless of
error_get_pretty().

http://marc.info/?l=qemu-devel&m=137513283408601&w=2

But, it is not reasonable to convert them at one time
because fprintf() is used everwhere in qemu.

So, it should be done step by step with avoiding regression.

This patch is based on Hu Tao's:
http://lists.nongnu.org/archive/html/qemu-devel/2013-08/msg00124.html

No need to hard-code pvpanic as part of the machine.
It can be added with "-device pvpanic" from command line (The next patch).
Anyway, for backport compatibility it is still part of 1.5
machine.

-pflash implies "new-style" ROM setup), there is no need anymore for a compat

use old-style setup.

from host (yet). Several issues turned up
(e.g. around winXP boot crashes). So it's safest to disable that

as we have enough time to fix issues if any.

cd7b87ffe9 target-i386: Fix X86CPU error handling
Error **errp argument is not for emitting warnings, it means an error
has occurred and the caller should not make any assumptions about the
state of other return values (unless otherwise documented).

Therefore cpu_x86_create() must unref the new X86CPU itself, and
pc_new_cpu() must check for an Error rather than NULL return value.

While at it, clean up a superfluous NULL check.

29b358f93a pci: Add root bus parameter to pci_nic_init()
At present, pci_nic_init() and pci_nic_init_nofail() assume that they will
only create a NIC under the primary PCI root.  As we add support for
multiple PCI roots, that may no longer be the case.  This patch adds a root
bus parameter to pci_nic_init() (and updates callers accordingly) to allow
the machine init code using it to specify the right PCI root for NICs
created by old-style -net nic parameters.  NICs created new-style, with
-device can of course be put anywhere.

1ef7a2a2af pci: Abolish pci_find_root_bus()
pci_find_root_bus() takes a domain parameter.  Currently PCI root buses
with domain other than 0 can't be created, so this is more or less a long
winded way of retrieving the main PCI root bus.  Numbered domains don't
actually properly cover the (non x86) possibilities for multiple PCI root
buses, so this patch for now enforces the domain == 0 restriction in other
places to replace pci_find_root_bus() with an explicit
pci_find_primary_bus().

00f4d64ee7 kvmclock: clock should count only if vm is running
kvmclock should not count while vm is paused, because:

1) if the vm is paused for long periods, timekeeping
math can overflow while converting the (large) clocksource
delta to nanoseconds.

2) Users rely on CLOCK_MONOTONIC to count run time, that is,
time which OS has been in a runnable state (see CLOCK_BOOTTIME).

Change kvmclock driver so as to save clock value when vm transitions
from runnable to stopped state, and to restore clock value from stopped
to runnable transition.

cb925cf923 KVM: PIC: Only commit irq routing when necessary
The current logic updates KVM's view of our interrupt map every time we
change it. While this is nice and bullet proof, it slows things down
badly for me. QEMU spends about 3 seconds on every start telling KVM what
news it has on its routing maps.

Instead, let's just synchronize the whole irq routing map as a whole when
we're done constructing it. For things that change during runtime, we can
still update the routing table on demand.

26a8ec0761 multiboot: Calculate upper_mem in the ROM
The upper_mem field of the Multiboot information struct doesn't really
contain the RAM size - 1 MB like we used to calculate it, but only the
memory from 1 MB up to the first (upper) memory hole.

In order to correctly retrieve this information, the multiboot ROM now
looks at the mmap it creates anyway and tries to find the size of
contiguous usable memory from 1 MB.

Drop the multiboot.c definition of lower_mem and upper_mem because both
are queried at runtime now.

39ae497239 Move hardcoded initialization of xen-platform device.
Creation of the xen-platform device is currently hardcoded into machine
type pc's initialization code, guarded by a test for the whether the xen
accelerator is enabled. This patch moves the creation of xen-platform into
the initialization code of the xenfv machine type. This maintains backwards
compatibility for that machine type but allows more flexibility if another
machine type is used with Xen HVM domains.

e1123015a5 pc: Make -no-fd-bootchk stick across boot order changes
Option -no-fd-bootchk asks the BIOS to attempt booting from a floppy
even when the boot sector signature isn't there, by setting a bit in
RTC CMOS.  It was added back in 2006 (commit 52ca8d6a).

Two years later, commit 0ecdffbb added monitor command boot_set.
Implemented by new function pc_boot_set().  It unconditionally clears
the floppy signature bit in CMOS.

Commit e0f084bf added -boot option once to automatically change the
boot order on first reset.  Reuses pc_boot_set(), thus also clears the
floppy signature bit.  Commit d9346e81 took care to preserve this
behavior.

Thus, -no-fd-bootchk applies to any number of boots.  Except it
applies just to the first boot with -boot once, and never after
boot_set.  Weird.  Make it stick instead: set the bit according to
-no-fd-bootchk in pc_boot_set().

The CPUID model values on Conroe, Penryn, and Nehalem are too

This causes at least one known problems: Windows XP disables sysenter
when (family == 6 && model <= 2), but Skype tries to use the sysenter
instruction anyway because it is reported as available on CPUID, making
it crash.

This patch sets appropriate model values that correspond to real Conroe,

Author: Igor Mammedov <imammedo@redhat.com>
Date:   Mon Apr 29 18:54:13 2013 +0200

    target-i386: Attach ICC bus to CPU on its creation

    X86CPU should have parent bus so it could provide bus for child APIC.

The commit makes it mandatory to pass a valid ICC bus to cpu_x86_create,
but cpu_x86_init just passes NULL to it.
xen_machine_pv uses cpu_x86_init, therefore it has been broken.

This patch fixes the problem by removing the dummy CPU creation
altogether from xen_init_pv, relying on the fact that QEMU can now cope
with a machine without an emulated CPU.

to be read/write memory rather than read-only memory.

KVM currently cannot support the BIOS as a ROM region, but qemu
in non-KVM mode can. Based on this, isapc machine currently only
works with KVM.

To work-around this isapc issue, this change avoids marking the
BIOS as readonly for isapc.

This change also will allow KVM to start supporting ROM mode
via KVM_CAP_READONLY_MEM.

This reverts commit 9953f8822c.
While Markus's analysis is entirely correct, there are 1.6 patches
that fix the bug for real and without requiring machine type hacks.
Let's think of the children who will have to read this code, and
avoid a complicated mess of semantics that differ between <1.5,
1.5, and >1.5.

0514ef2fbb target-i386: Replace cpuid_*features fields with a feature word array
This replaces the feature-bit fields on both X86CPU and x86_def_t
structs with an array.

With this, we will be able to simplify code that simply does the same
operation on all feature words (e.g. kvm_check_features_against_host(),
filter_features_for_kvm(), add_flagname_to_bitmaps(), CPU feature-bit
property lookup/registration, and the proposed "feature-words" property)

The following field replacements were made on X86CPU and x86_def_t:

  (cpuid_)features         -> features[FEAT_1_EDX]
  (cpuid_)ext_features     -> features[FEAT_1_ECX]
  (cpuid_)ext2_features    -> features[FEAT_8000_0001_EDX]

9953f8822c pc: Kill the "use flash device for BIOS unless KVM" misfeature
Use of a flash memory device for the BIOS was added in series "[PATCH
v10 0/8] PC system flash support", commit 4732dca..1b89faf, v1.1.

Flash vs. ROM is a guest-visible difference.  Thus, flash use had to
be suppressed for machine types pc-1.0 and older.  This was
accomplished by adding a dummy device "pc-sysfw" with property
"rom_only":

* Non-zero rom_only means "use ROM".  Default for pc-1.0 and older.
* Zero rom_only means "maybe use flash".  Default for newer machines.

Not only is the dummy device ugly, it was also retroactively added to
the older machine types!  Fortunately, it's not guest-visible (thus no
immediate guest ABI breakage), and has no vmstate (thus no immediate
migration breakage).  Breakage occurs only if the user unwisely
enables flash by setting rom_only to zero.  Patch review FAIL #1.

Why "maybe use flash"?  Flash didn't (and still doesn't) work with
KVM.  Therefore, rom_only=0 really means "use flash, except when KVM
is enabled, use ROM".  This is a Bad Idea, because it makes enabling/
disabling KVM guest-visible.  Patch review FAIL #2.

Aside: it also precludes migrating between KVM on and off, but that's
not possible for other reasons anyway.

Fix as follows:

1. Change the meaning of rom_only=0 to mean "use flash, no ifs, buts,
or maybes" for pc-i440fx-1.5 and pc-q35-1.5.  Don't change anything
for older machines (to remain bug-compatible).

2. Change the default value from 0 to 1 for these machines.
Necessary, because 0 doesn't work with KVM.  Once it does, we can flip
the default back to 0.

3. Don't revert the retroactive addition of device "pc-sysfw" to older
machine types.  Seems not worth the trouble.

4. Add a TODO comment asking for device "pc-sysfw" to be dropped once
flash works with KVM.

Net effect is that you get a BIOS ROM again even when KVM is disabled,
just like for machines predating the introduction of flash.

To get flash instead, use "--global pc-sysfw.rom_only=0".

d8ed887bdc exec: Pass CPUState to cpu_reset_interrupt()
Move it to qom/cpu.c to avoid build failures depending on include order
of cpu-qom.h and exec/cpu-all.h.

Change opaques of various ..._irq_handler() functions to the
appropriate CPU type to facilitate using cpu_reset_interrupt().

Fix Coding Style issues while at it (missing braces, indentation).

259186a7d2 cpu: Move halted and interrupt_request fields to CPUState
Both fields are used in VMState, thus need to be moved together.
Explicitly zero them on reset since they were located before
breakpoints.

Pass PowerPCCPU to kvmppc_handle_halt().

ee0cc5415e hw: Add test device for unittests execution
Add a test device which supports the kvmctl ioports,
so one can run the KVM unittest suite.

Intended Usage:

qemu-system-x86_64 -nographic \
    -device pc-testdev \
    -device isa-debug-exit,iobase=0xf4,iosize=0x04 \
    -kernel /path/to/kvm/unittests/msr.flat

Where msr.flat is one of the KVM unittests, present on a
separate repo,

git://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git

bb355b1859 add isa-debug-exit device.
When present it makes qemu exit on any write.
Mapped to port 0x501 by default.

Without this patch Anthony doesn't allow me to
remove the bochs bios debug ports because his
test suite uses this.

df2d8b3ed4 q35: Introduce q35 pc based chipset emulator
pc q35 based chipset emulator to support pci express natively. Based on
Anthony Liguori's suggestion, the machine name is 'q35-next', with an alias
of 'q35'. At this point, there are no compatibility guarantees. When the
chipset stabilizes more, we will begin to version the machine names.

Major features which still need to be added:

-Migration support (mostly around ahci)
-ACPI hotplug support (pcie hotplug support is working)
-Passthrough support
