a31a864273 acpi: add rules to compile ASL source
Detect presence of IASL compiler and use it
to process ASL source. If not there, use pre-compiled
files in-tree. Add script to update the in-tree files.

Note: distros are known to silently update iasl
so detect correct iasl flags for the installed version on each run as
opposed to at configure time.

74523b8501 i386: add ACPI table files from seabios
This adds ASL code as well as scripts for processing it,
imported from seabios git tree
commit 51684b7ced75fb76776e8ee84833fcfb6ecf12dd

Will be used for runtime acpi table generation.

Note:
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
side of caution and include them.

Affected SeaBIOS files (GPLv2+ license headers added)

Interrupt pin is selected and saved into PCI_INTERRUPT_PIN
register during device initialization. Devices should not call
directly qemu_set_irq and specify the INTx pin on each call.

Added pci_* wrappers to replace qemu_set_irq, qemu_irq_raise,
qemu_irq_lower and qemu_irq_pulse, setting the irq
based on PCI_INTERRUPT_PIN.

Added pci_allocate_irq wrapper to be used by devices that
still need PCIDevice infrastructure to assert irqs.

Renamed a static method which was named already pci_set_irq.

a1ff8ae066 memory: Change MemoryRegion priorities from unsigned to signed
When memory regions overlap, priority can be used to specify
which of them takes priority. By making the priority values signed
rather than unsigned, we make it more convenient to implement
a situation where one "background" region should appear only
where no other region exists: rather than having to explicitly
specify a high priority for all the other regions, we can let them take
the default (zero) priority and specify a negative priority for the
background region.

fc3b32958a 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).

Bonus cleanup: qemu_uuid_parse() no longer sets SMBIOS system uuid by
side effect.

ec2df8c10a smbios: Improve diagnostics for conflicting entries
We allow either tables or fields for the same type.  Makes sense,
because SeaBIOS uses fields only when no tables are present.

We do this by searching the SMBIOS blob for a previously added table
or field.  Error messages look like this:

    qemu-system-x86_64: -smbios type=1,serial=42: SMBIOS type 1 table already defined, cannot add field

User needs to know that "table" is defined by -smbios file=..., and
"field" by -smbios type=...

Instead of searching the blob, record additions of interest, and check
that.  Simpler, and makes better error messages possible:

    qemu-system-x86_64: -smbios file=smbios_type_1.bin: Can't mix file= and type= for same type
    qemu-system-x86_64: -smbios type=1,serial=42,serial=99: This is the conflicting setting

c58c7b959b qxl: fix local renderer
The local spice renderer assumes the primary surface is located at the
start of the "ram" bar.  This used to be a requirement in qxl hardware
revision 1.  In revision 2+ this is relaxed.  Nevertheless guest drivers
continued to use the traditional location, for historical and backward
compatibility reasons.  The qxl kms driver doesn't though as it depends
on qxl revision 4+ anyway.

Result is that local rendering is hosed for recent linux guests, you'll
get pixel garbage with non-spice ui (gtk, sdl, vnc) and when doing
screendumps.  Fix that by doing a proper mapping of the guest-specified
memory location.

94c2b6aff4 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.
