d350d97d19 pci: add default pci subsystem id for all devices (Gerd Hoffman)
This sets a default PCI subsystem ID for all emulated PCI devices.  PCI
specs require this, so do it.

In many cases it is enougth to know the PCI ID to handle a device
correctly.  Sometimes a device driver must identify the exact piece of
hardware (via PCI Subsystem ID) though.

What does this patch to qemu devices:

Right now the emulated PCI devices have no PCI subsystem ID, only the
PCI ID.  The discussed patch sets a default PCI subsystem ID for all
emulated devices.  Which will make the qemu devices look pretty much
like in the laptop case: all PCI subsystem IDs will point to qemu by
default.

If a driver emulates a very specific piece of hardware where it has to
emulate more than just the PCI chip, it can overwrite the PCI subsystem
ID without problems.  The es1370 driver does that for example.

85df0de4cf Allow to register a callback with fw_cfg_add_callback()
fw_cfg_add_callback() checks if key has FW_CFG_WRITE_CHANNEL bit set
after masking the key with FW_CFG_ENTRY_MASK.

But as FW_CFG_ENTRY_MASK is ~(FW_CFG_WRITE_CHANNEL | FW_CFG_ARCH_LOCAL),
the bit is never set and function exits.

This patch corrects this by checking the bit before masking the value.

dd8edf0122 Add 64-bit Block Move support (Direct & Table Indirect) (Ryan Harper)
This patch adds support for 64-bit Block Move instructions.  There are multiple
modes for 64-bit Block moves, direct, indirect, and table indirect.  This patch
implements Direct and Table indirect moves which are needed by 64-bit windows
and SYM_CONF_DMA_ADDRESSING_MODE=2 for the Linux sym53c8xx_2 driver respectively.

Two helper functions are included to check which mode the guest is using.  For
 64-bit direct moves, we fetch a 3rd DWORD and store the value in the DBMS
register.  For Table Indirect moves, we look into the table for which register
contains the upper 32-bits of the 64-bit address.  This selector value indicates
which register to pull the value from and into dnad64 register.

Finally, lsi_do_dma is updated to use the approriate register to build a 64-bit
DMA address if required.

With this patch, Windows XP x64, 2003 SP2 x64, can now install to scsi devices.
Linux SYM_CONF_DMA_ADDRESSING_MODE=2 need a quirk fixup in Patch 4 to function
properly.

4efbe58fb5 MIPS Magnum: fix memory-mapped i8042
Current implementation of memory-mapped i8042 controller is atm
implemented with an interface shift (it_shift) parameter, like most all
memory-mapped devices in Qemu.
However, this isn't suitable for MIPS Magnum, where i8042 controller is at
0x80005000 up to 0x80005fff.

Thomas Bogendoerfer (from #mipslinux) tested the behaviour of a real
machine, and found that odd addresses are for status/command register, and
even addresses for data register.

Attached patch implements this behaviour by replacing the it_shift
parameter by a mask one.
Incidentally, keyboard now works on OpenBSD 2.3, which accesses i8042
controller at 0x80005060 and 0x80005061.

f65ed4c152 KVM: Coalesced MMIO support
MMIO exits are more expensive in KVM or Xen than in QEMU because they 
involve, at least, privilege transitions.  However, MMIO write 
operations can be effectively batched if those writes do not have side 
effects.

Good examples of this include VGA pixel operations when in a planar 
mode.  As it turns out, we can get a nice boost in other areas too.  
Laurent mentioned a 9.7% performance boost in iperf with the coalesced 
MMIO changes for the e1000 when he originally posted this work for KVM.

d1f193b0ed SH4: SCI improvement
This patch simply implement one register of SH4's SCI := Serial Communication Interface.

R2D evaluation board uses SCI for SPI connection.  So, Linux kernel for R2D with
default configuration causes a QEMU assertion failure when it initializes SPI driver.
This patch avoids it and reduces the kernel config modification work for QEMU.

Completing SCI implementation task is left.  Other board support is desirable to confirm
this task, which uses SCI for a serial terminal.

5c16736a37 SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).
Main purpose of this is to delete
       *physical = address & 0x1fffffff;
at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.

Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.

Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

This patch adds pci support to sh/r2d board.
This is the first user of PCIC support I formerly sent.

PCIC actually is inside of chip with CPU core on SH7751.
But, this code is written as if SH7750 and PCIC are on board.
I care little about physical device boundary, but fitting with qemu's
design.

This patch also adds some BSC (Bus State Controller) registers,
because PCI device driver software have to accesses them.

02b373ad5d LSI53C895A: Handle empty SCRIPTS opcode (Justin Chevrier)
Basically after each DMA transfer the Openserver driver would issue an
empty (0) SCRIPTS opcode. As the opcode is essentially a NOP it has no
second DWORD and therefore the DSP should only be incremented by 4 bytes
instead of the 8 bytes we currently do.

Here's a snippet of the log:

lsi_scsi: Data ready tag=0x100d9 len=16384
...
lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a09000
lsi_scsi: DMA addr=0x07a09000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e58 opcode 00000000 arg 01000400
lsi_scsi: Wrong phase got 1 expected 0

Note the 2nd DWORD after the empty opcode; the next opcode in the DMA
transfer sequence. As can be expected the address after that has the next
DMA address to use.

After the attached patch the DMA transfer is able to complete successfully:

lsi_scsi: SCRIPTS dsp=068c5e50 opcode 01000400 arg 07a0d000
lsi_scsi: DMA addr=0x07a0d000 len=1024
lsi_scsi: SCRIPTS dsp=068c5e5c opcode 01000400 arg 07a0d400
lsi_scsi: DMA addr=0x07a0d400 len=1024
...

Tested againsted Openserver 5.0.5 and Debian ARM.

bf9298b90e Make struct iovec universally available
Vectored IO APIs will require some sort of vector argument.  It makes sense to
use struct iovec and just define it globally for Windows.

b2b183c270 do boundary check based on absolute value (Glauber Costa)
For backward operations, dstpitch and srcpitch can
be negative. This leads BLTUNSAFE macro into an
overflow, and as a result, it avoids performing
operations that are perfectly valid.

The visible effect that led to that patch was the gnome-panel
bar in Fedora10. Before this patch, you could see garbage
clobbering a big portion of the bar.

After this patch, this garbage is gone.

0cd2df75a2 Fix RTC initial date computation
qemu_get_clock() returns a structure containing the time the user wants
to be set (either UTC time, a local time, or a given date). Use mktimegm()
instead of mktime() to convert it into POSIX time without taking the host
timezone into account.

bd3220870f Add virtio-balloon support
This adds a VirtIO based balloon driver.  It uses madvise() to actually balloon
the memory when possible.

Until 2.6.27, KVM forced memory pinning so we must disable ballooning unless the
kernel actually supports it when using KVM.  It's always safe when using TCG.

f46f15bca7 Remove TARGET_PAGE_SIZE from virtio interface (Hollis Blanchard)
TARGET_PAGE_SIZE should only be used internal to qemu, not in guest/host
interfaces. The virtio frontend code in Linux uses two constants (PFN shift
and vring alignment) for the interface, so update qemu to match.

I've tested this with PowerPC KVM and confirmed that it fixes virtio problems
when using non-TARGET_PAGE_SIZE pages in the guest.

6e02c38dad Add virtio-blk support
Virtio-blk is a paravirtual block device based on VirtIO.  It can be used by
specifying the if=virtio parameter to the -drive parameter.

When using -enable-kvm, it can achieve very good performance compared to IDE or
SCSI.
