Have qxl_get_check_slot_offset() return false if the requested
buffer size does not fit within the slot memory region.
Similarly qxl_phys2virt() now returns NULL in such case, and
qxl_dirty_one_surface() aborts.
This avoids buffer overrun in the host pointer
From: Philippe Mathieu-Daudé
Only 3 command types are logged: no need to call qxl_phys2virt()
for the other types. Using different cases will help to pass
different structure sizes to qxl_phys2virt() in a pair of commits.

Migration code has a lot to do with host pages. Teaching PSS core about

this prepares for the future changes that can leverage the new PSS helpers

Hi Philippe,
Hi Gowri,
The zcu102 has a zynqmp soc object (hw/arm/xlnx-zcu102.c:125):
static void xlnx_zcu102_init(MachineState *machine)
{
...
object_initialize_child(OBJECT(machine), "soc", >soc, TYPE_XLNX_ZYNQMP);
So the TTCs should work in the ZCU102.

When accsssing /proc/self/exe from a userspace program, linux-user tries
to resolve the name via realpath(), which may fail if the process
changed the working directory in the meantime.
An example:

- the program runs chdir("/tmp")

I don't understand this part of HAXM enough, but per your explanation,
your change looks correct.

Don't take the bitmap mutex when sending pages, or when being throttled by
migration_rate_limit() (which is a bit tricky to call it here in ram code,
but seems still helpful).

From: Peter Xu
Since we use PageSearchStatus to represent a channel, it makes perfect
sense to keep last_sent_block (aka, leverage RAM_SAVE_FLAG_CONTINUE) to be
per-channel rather than global because each channel can be sending
different pages on ramblocks.
Hence move it from RAMState into
From: Peter Xu
Now with rs->pss we can already cache channels in pss->pss_channels. That
pss_channel contains more infromation than rs->f because it's per-channel.
So rs->f could be replaced by rss->pss[RAM_CHANNEL_PRECOPY].pss_channel,
while rs->f itself is a bit vague now.
Note that vanilla
It was only used for RAM, and in that case, it means that this amount
