This patch reuses some code from SeaBIOS, which was originally under
LGPLv2 and then relicensed to GPLv3 or LGPLv3, in QEMU under GPLv2+. This
relicensing has been acked by all contributors that had contributed to the
code since the v2->v3 relicense. ACKs approving the v2+ relicensing are
listed below. The list might include ACKs from people not holding
copyright on any parts of the reused code, but it's better to err on the

smbios: Make multiple -smbios type= accumulate sanely
Currently, -smbios type=T,NAME=VAL,... adds one field (T,NAME) with
value VAL to fw_cfg for each unique NAME. If NAME occurs multiple
times, the last one's VAL is used (before the QemuOpts conversion, the
first one was used).
Multiple -smbios can add multiple fields with the same (T, NAME).
SeaBIOS reads all of them from fw_cfg, but uses only the first field
(T, NAME). The others are ignored.
"First one wins, subsequent ones get ignored silently" isn't nice. We
commonly let the last option win. Useful, because it lets you
-readconfig first, then selectively override with command line
options.
Clean up -smbios to work the common way. Accumulate the settings,
with later ones overwriting earlier ones. Put the result into fw_cfg
(no more useless duplicates).

For newer target architectures, glibc can be picky about the kernel

enhancing the existing support for faking the kernel version so
that each target can optionally specify a minimum version: if

with the minimum required version only if the real host kernel

target-arm: fix ARMv7M stack alignment on reset
When the initial SP is loaded from the vector table on ARMv7M systems the two
least significant bits are ignored as the stack is always aligned at a four byte
boundary (see ARM DDI 0403C, B1.4.1 and B1.5.5). So far QEMU did not ignore
these bits leading to a stack alignment inconsitent with real hardware for
binaries that rely on this behaviour. This patch fixes this issue by masking the

qemu-ga: Add Windows VSS provider and requester as DLL
Adds VSS provider and requester as a qga-vss.dll, which is loaded by
Windows VSS service as well as by qemu-ga.
"provider.cpp" implements a basic stub of a software VSS provider.
Currently, this module only relays a frozen event from VSS service to the
agent, and thaw event from the agent to VSS service, to block VSS process
to keep the system frozen while snapshots are taken at the host.
To register the provider to the guest system as COM+ application, the type
library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl),
VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also
adds pre-compiled .tlb file in the repository in order to enable
cross-compile qemu-ga.exe for Windows with VSS support.
"requester.cpp" provides the VSS requester to kick the VSS snapshot process.
Qemu-ga.exe works without the DLL, although fsfreeze features are disabled.
These functions are only supported in Windows 2003 or later. In older
systems, fsfreeze features are disabled.
In several versions of Windows which don't support attribute
VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error
VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error.
To solve this fundamentally, we need a framework to handle mount writable
snapshot on guests, which is required by VSS auto-recovery feature
(cleanup phase after a snapshot is taken).

mips_malta: support up to 2GiB RAM
A Malta board can support up to 2GiB of RAM. Since the unmapped kseg0/1
regions are only 512MiB large & the latter 256MiB of those are taken up
by the IO region, access to RAM beyond 256MiB must be done through a
mapped region. In the case of a Linux guest this means we need to use
highmem.
The mainline Linux kernel does not support highmem for Malta at this
time, however this can be tested using the linux-mti-3.8 kernel branch
available from:
git://git.linux-mips.org/pub/scm/linux-mti.git
You should be able to boot a Linux kernel built from the linux-mti-3.8
branch, with CONFIG_HIGHMEM enabled, using 2GiB RAM by passing "-m 2G"
to QEMU and appending the following kernel parameters:
mem=256m@0x0 mem=256m@0x90000000 mem=1536m@0x20000000
Note that the upper half of the physical address space of a Malta
mirrors the lower half (hence the 2GiB limit) except that the IO region
(0x10000000-0x1fffffff in the lower half) is not mirrored in the upper
half. That is, physical addresses 0x90000000-0x9fffffff access RAM
rather than the IO region, resulting in a physical address space
resembling the following:
0x00000000 -> 0x0fffffff RAM
0x10000000 -> 0x1fffffff I/O
0x20000000 -> 0x7fffffff RAM
0x80000000 -> 0x8fffffff RAM (mirror of 0x00000000 -> 0x0fffffff)
0x90000000 -> 0x9fffffff RAM
0xa0000000 -> 0xffffffff RAM (mirror of 0x20000000 -> 0x7fffffff)
The second mem parameter provided to the kernel above accesses the
second 256MiB of RAM through the upper half of the physical address
space, making use of the aliasing described above in order to avoid
the IO region and use the whole 2GiB RAM.
The memory setup may be seen as 'backwards' in this commit since the
'real' memory is mapped in the upper half of the physical address space
and the lower half contains the aliases. On real hardware it would be
typical to see the upper half of the physical address space as the alias
since the bus addresses generated match the lower half of the physical
address space. However since the memory accessible in the upper half of
the physical address space is uninterrupted by the IO region it is
easiest to map the RAM as a whole there, and functionally it makes no
difference to the target code.
Due to the requirements of accessing the second 256MiB of RAM through
a mapping to the upper half of the physical address space it is usual
for the bootloader to indicate a maximum of 256MiB memory to a kernel.
This allows kernels which do not support such access to boot on systems
with more than 256MiB of RAM. It is also the behaviour assumed by Linux.
QEMUs small generated bootloader is modified to provide this behaviour.
