Currently, for emulated PIO transfers through the AHCI device,
any attempt made to request more than a single sector's worth
of data will result in the same sector being transferred over
and over.
For example, if we request 8 sectors via PIO READ SECTORS, the
AHCI device will give us the same sector eight times.
This patch adds offset tracking into the PIO pathways so that
we can fulfill these requests appropriately.

This patch fixes a regression caused by commit
659142ecf7.
The problem occurs when we wish to return early
from the ahci_start_transfer function, but are now
updating the transferred byte count in the AHCI
command header via ahci_commit_buf.
This will cause problems in the Windows 8 installer.
Don't update the byte count in the command header
for the transmission of ATAPI packets: These commands
will distort the final byte count of the actual data
payload.
The call to ahci_commit_buf remains in the "out"
portion of the call in order to clean up the sglist.
The byte count is maintained by forcing size to be 0.

The 'QemuConsole' is the input source for handler, we share some
input handlers to process the input events from different QemuConsole.
Normally we only have one set of keyboard, mouse, usbtablet, etc.
The devices have different mask, it's fine to just checking mask to
insure that the handler has the ability to process the event.
I saw we try to bind console to handler in usb/dev-hid.c, but display
always isn't available at that time.
If we have multiseat setup (as Gerd said), we only have 'problem' in
this case. Actually event from different devices have the same effect
for system, it's fine to always use the first available handler
without caring about the console.
For send-key command, we just pass a NULL for console parameter in
calling qemu_input_event_send_key(NULL, ..), but 'input-send-event'
needs to care more devices.
Conclusion:
Generally assigning the special console is meanless, and we can't
directly remove the QMP parameter for compatibility.
So we can make the parameter optional. The parameter might be useful
for some special condition: we have multiple devices without binding
console and they all have the ability(mask) to process events, and
we don't want to use the first one.

In my tests fadvise64() is called 50--51 times per VM run. That

This is a simple patch to change the type of old_env from jmp_buf
to sigjmp_buf. old_env is used by sigsetjmp and as such should be
a sigjmp_buf.
This fixes a stack_chk fail in a OSX 32bit build. Since at least on
OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an
overflow in sigsetjmp. Due to variable reordering this overwrites
the stack cookie.

When creating a timer handle, we give the timer id a special magic offset
of 0xcafe0000. However, we never mask that offset out of the timer id before
we start using it to dereference our timer array. So we always end up aborting
timer operations because the timer id is out of bounds.
This was not an issue before my patch e52a99f756 ("linux-user: Simplify
timerid checks on g_posix_timers range") because before we would blindly mask
anything above the first 16 bits.
This patch simplifies the code around timer id creation by introducing a proper
target_timer_id typedef that is s32, just like Linux has it. It also changes the
magic offset to a value that makes all timer ids be positive.

For Linux upstream kernel (e.g. 3.17-rc7), the related compatible string
'xlnx,xps-ethernetlite-2.00.a' is supported, but 'b' is not supported,
so change qemu dtb file to match kernel driver.

ip link set tap0 up
brctl addif virbr0 tap0
./configure

in microblaze qemu bash (guest machine):
ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0

Option 'disable spoolss' is available since Samba 2.0.4, commit
de5f42c9d9172592779fa2504d44544e3b6b1c0d).
Next, "socket address" was reported as deprecated, use a combination of
"interfaces" and "bind interfaces only" instead (available since October
1997, commit 79f4fb52c1ed56fd843f81b4eb0cdd2991d4d0f4).

Entry opcode needs to check if moving to new register frame would cause
register window overflow. Entry used in function prologue never
overflows because preceding windowed call* opcode writes return address
to the target register window frame, causing overflow exceptions at the
point of call. But when a sequence of entry opcodes is used for register
window spilling there may not be a call or other opcode that would cause
window check between entries and they would not raise overflow exception
themselves resulting in data corruption.
