qemu tracks guest time based on vector [base_rtc, last_update], in which
last_update stands for a monotonic tick which is actually uptime of the
host.
according to rtc implementation codes of recent releases and upstream,
after
migration, the time base vector [base_rtc, last_update] isn't updated to
coordinate with the destionation host, ie. qemu doesnt update last_update
to
uptime of the destination host.
what problem have we got because of this bug? after migration, guest time
may
jump back to several days ago, that will make some critical business
applications,
such as lotus notes, malfunction.
this patch is trying to fix the problem. first, when vmsave in progress,
we
rtc_update_time to refresh time stamp in cmos array, then during
vmrestore,
we rtc_set_time to update qemu base_rtc and last_update variable according
to time
stamp in cmos array.

ATA8-APT defines the state transitions for both a host controller and
for the hardware device during the lifecycle of a DMA transfer, in
section 9.7 "DMA command protocol."
One of the interesting tidbits here is that when a device transitions
from DDMA0 ("Prepare state") to DDMA1 ("Data_Transfer State"), it can
choose to set either BSY or DRQ to signal this transition, but not both.
as ide_sector_dma_start is the last point in our preparation process
before we begin the real data transfer process (for either AHCI or BMDMA),
this is the correct transition point for DDMA0 to DDMA1.
I have chosen !BSY && DRQ for QEMU to make the transition from DDMA0 the
most obvious.

It turned out that re-entrant ioq_submit() and completion processing
between three requests caused this error. The following check is not
sufficient to prevent recursively entering coroutines:
if (laiocb->co != qemu_coroutine_self()) {
qemu_coroutine_enter(laiocb->co);

Use the new qemu_coroutine_entered() function instead of comparing
against qemu_coroutine_self(). This is correct because:
1. If a coroutine is not entered then it must have yielded to wait for
I/O completion. It is therefore safe to enter.
2. If a coroutine is entered then it must be in
ioq_submit()/qemu_laio_process_completions() because otherwise it
would be yielded while waiting for I/O completion. Therefore it will
check laio->ret and return from ioq_submit() instead of yielding,
i.e. it's guaranteed not to hang.

Change ps2_put_keycode to get an untranslated scancode, which is translated if needed.
As qemu_input_key_value_to_scancode() gives translated scancodes, untranslate them
in ps2_keyboard_event first before giving them to ps2_put_keycode.
Results are not changed, except for some keys in translated set 3.

This switches over spice (in opengl mode) to render DisplaySurface
updates into a opengl texture, using the helper functions in
ui/console-gl.c. With this patch applied spice (with gl=on) will
stop using qxl rendering ops, it will use dma-buf passing all the
time, i.e. for bios/bootloader (before virtio-gpu driver is loaded)
too.
This should improve performance even using spice (with gl=on) with
non-accelerated stdvga because we stop squeezing all display updates
through a unix/tcp socket and basically using a shared memory transport
instead.

virtio-gpu does a set-scanout at each frame (it might be a driver
regression). qemu_console_resize() recreate a surface even if the size
didn't change, and this shows up in profiling reports because the
surface is cleared. With this patch, I get a +15-20% glmark2
improvement.

"vq->desc[i].addr" is a 64bit value,
so write it with writeq(), not writew().
struct vring_desc {
__virtio64 addr;
__virtio32 len;
__virtio16 flags;
__virtio16 next;
};

if iothread->ctx is set to NULL, aio_context_unref triggers the assertion:
g_source_unref: assertion 'source != NULL' failed.
The patch fixes it.

As epoll whether enabled or not is a global setting, we can just
check it only once rather than checking it with every node iteration.
Through this we can avoid a lot of checks when epoll is not enabled.

In the CRIS v17 CPU an ADDC (add with carry) instruction has been added
compared to the v10 instruction set.
Assembler syntax:
ADDC [Rs],Rd
ADDC [Rs+],Rd
Size: Dword
Description:
The source data is added together with the carry flag to the
destination register. The size of the operation is dword.
Operation:
Rd += s + C-flag;
Flags affected:
S R P U I X N Z V C
- - - - - 0 * * * *
Instruction format: ADDC [Rs],Rd
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|Destination(Rd)| 1 0 0 1 1 0 1 0 | Source(Rs) |
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
