Michael S. Tsirkin 4a4fcdf6df MAINTAINERS: drop an out of date address
Gleb's address seems to be out of date.  Since it stayed like that for a
while now, I'm guessing he's no longer interested in getting mail.

Igor Mammedov 6e1f0a55a1 PCIE: fix regression with coldplugged multifunction device
PCIE is causing asserts each time a multifunction device is added
on command line (coldplug).

This is caused by
commit a66e657e18
    pci/pcie: convert PCIE hotplug to use hotplug-handler API
QEMU abort is caused by misplaced assertion, which should
be checked only when device is hotplugged.

Reference to regression report:
 http://www.mail-archive.com/qemu-devel@nongnu.org/msg216226.html

Fixes: a66e657e18

Igor Mammedov 8e46bbf362 memory_region_present: return false if address is not found in child MemoryRegion
Windows XP shows COM2 port as non functional in
"Device Manager" although no COM2 port backing device
is present in QEMU.

This regression is really due to
3bb28b7208b349e7a1b326e3c6ef9efac1d462bf?
    memory: Provide separate handling of unassigned io ports accesses

That is caused by the fact that QEMU reports to
OSPM that device is present by setting 5th bit in
PII4XPM.pci_conf[0x67] register when COM2 doesn't
exist.

It happens due to memory_region_present(io_as, 0x2f8)
returning false positive since 0x2f8 address eventually
translates into catchall io_as address space.

Fix memory_region_present(parent, addr) by returning
true only if addr maps into a MemoryRegion within
parent (excluding parent itself), to match its
doc comment.

While at it fix copy/paste error in
memory_region_present() doc comment.

Note: this is a temporary hack: we really need better handling for
unassigned regions, we should avoid fallback regions since they are bad
for performance (breaking radix tree assumption that the data structure
is sparsely populated); for memory we need to fix this to implement PCI
master abort properly, anyway.

Michael S. Tsirkin 8dcf525abc acpi-build: append description for non-hotplug
As reported in
http://article.gmane.org/gmane.comp.emulators.qemu/253987
Mac OSX actually requires describing all occupied slots
in ACPI - even if hotplug isn't enabled.

I didn't expect this so I dropped description of all
non hotpluggable slots from ACPI.
As a result: before
commit 99fd437dee (enable
hotplug for pci bridges), PCI cards show up in the "device tree" of OS X
(System Information). E.g., on MountainLion users have:

Hardware -> PCI Cards:

  Card          Type                 Driver Installed  Slot
 *ethernet      Ethernet Controller  Yes               PCI Slot 2
  pci8086,2934  USB UHC              Yes               PCI Slot 29

  ethernet:

    MSI:                  No

    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Slot                  PCI Slot 2
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

After commit 99fd437dee, users get:

Hardware -> PCI Cards:

  This computer doesn't contain any PCI cards. If you installed PCI
  cards, make sure they're properly installed.

Hardware -> Ethernet Cards

  ethernet:
    Type:                 Ethernet Controller
    Bus:                  PCI
    Vendor ID:            0x8086
    Device ID:            0x100e
    Subsystem Vendor ID:  0x1af4
    Subsystem ID:         0x1100
    Revision ID:          0x0003
    BSD name:             en0
    Kext name:            AppleIntel8254XEthernet.kext
    Location:             /System/Library/Extensions/...
    Version:              3.1.1b1

Ethernet still works, but it's not showing up on the PCI bus, and it
no longer thinks it's plugged in to slot #2, as it used to before the
change.

To fix, append description for all occupied non hotpluggable PCI slots.

One need to be careful when doing this: VGA devices
are now described in SSDT, so we need to drop description from DSDT.
And ISA devices are used in DSDT so drop them from SSDT.

              {'actions': [
                  { 'type': 'blockdev-snapshot-sync', 'data' :

Peter Maydell 4c288acbd6 configure: Always build with -fno-common
MacOSX doesn't pull .o files from .a archives if the symbol that it
requires is one which the .o file defines as a common symbol.
(Common symbols are those declared without "extern"; the linker
will merge together common symbols with the same name, so
redeclaring the same variable in two compilation units results in
them referring to the same symbol rather than a compilation error).

This MacOSX difference from traditional linker behaviour means that
"make check" produces link errors:

Undefined symbols for architecture x86_64:
  "_cur_mon", referenced from:
      _error_vprintf in libqemuutil.a(qemu-error.o)
      _error_printf in libqemuutil.a(qemu-error.o)
      _error_printf_unless_qmp in libqemuutil.a(qemu-error.o)
      _error_print_loc in libqemuutil.a(qemu-error.o)
      _error_report in libqemuutil.a(qemu-error.o)
ld: symbol(s) not found for architecture x86_64

in this case because "cur_mon" is a common symbol in
libqemustub.a(mon-set-error.o).

In QEMU we don't make any use at all of the common symbol
functionality, so we can avoid this problem entirely simply
by compiling with -fno-common. Enable this option for all
builds, not just MacOSX, so that if we ever inadvertently
introduce multiple definitions of some variable that will
be immediately spotted as a build error rather than only
breaking the MacOSX build.

Peter Maydell 9c83ffd859 configure: Make C++ test work with --enable-werror
gcc's C++ compiler complains about being passed some -W options
which make sense for C but not for C++. This means we mustn't try
a C++ compile with QEMU_CFLAGS, but only with a filtered version
that removes the offending options. This filtering was already being
done for uses of C++ in the build itself, but was omitted for the
"does C++ work?" configure test. This only showed up when doing
builds which explicitly enabled -Werror with --enable-werror,
because the "do the compilers work" tests were mistakenly placed
above the "default werror based on whether compiling from git" code.
Another error in this category is that clang warns if you ask it to
compile C++ code from a file named "foo.c". Further, because we
were running do_cc in a subshell in the condition part of an "if",
the error_exit inside do_compiler wouldn't terminate configure and
we would plunge on regardless. Fix this complex of errors:

1. Move the default-werror code up so that there are no invocations
of compile_object and friends between it and the point where we
set $werror explicitly based on the --enable-werror command line
option.

2. Provide a mechanism for filtering QEMU_CFLAGS to create
QEMU_CXXFLAGS, and use it for the test we run here.

3. Provide a do_cxx function to run a test with the C++ compiler
rather than doing cute tricks with subshells and do_cc.

4. Use a new temporary file TMPCXX for the C++ program fragment.

Kevin Wolf eb909c7f72 block: Fix error path segfault in bdrv_open()
Using an invalid option for a block device that is opened with
BDRV_O_PROTOCOL led to drv = NULL, and when trying to include the driver

    $ x86_64-softmmu/qemu-system-x86_64 -drive file=/tmp/test.qcow2,file.foo=bar
    Segmentation fault (core dumped)

With this patch applied, the expected error message is printed:

Max Reitz cd5d031e75 block: Keep "filename" option after parsing
Currently, bdrv_file_open() always removes the "filename" option from
the options QDict after bdrv_parse_filename() has been (successfully)
called. However, for drivers with bdrv_needs_filename, it makes more
sense for bdrv_parse_filename() to overwrite the "filename" option and
for bdrv_file_open() to fetch the filename from there.

Since there currently are no drivers that implement
bdrv_parse_filename() and have bdrv_needs_filename set, this does not
change current behavior.

Moving only the node_name one field could lead to some inconsitencies where a
node_name was defined on a bs which was not registered in the graph node list.

bdrv_swap between a named node bs and a non named node bs would lead to this.

bdrv_make_anon would then crash because it would try to remove the bs from the
graph node list while it is not in it.

then insert them back.
