Hello, all
I am reviewing source of Qemu. I can see parameter called opaque from a lot
of function like this:
//@hw/timer/xilinx_timer.c
static uint64_t timer_read(void *opaque, hwaddr addr, unsigned int size)
{
...
}
, and its meaning confuse me. What does opaque stand for?
Thanks,
When bs-filename and bs-backing_file are relative pathname and not under the
same directory, path_combine() can not give the correct path for
bs-backing_file. So add get_localfile_absolute_path to get absolute path for
local file.
e.g:
$ pwd
/tmp
$ /opt/qemu-git-arm/bin/qemu-img create -f qcow2

Old BIOSes left some padding by mistake after the req_size/resp_size.
New QEMU does not like it, thinking it is a bidirectional command.
As a workaround, we can check if the ANY_LAYOUT bit is set; if not, we
always consider the first buffer as the virtio-scsi request/response,
because, back when

Hi Alvise,
I now got to test the series for my use case, in particular to enable the
ARM 64bit OSv guest (OSv's devices come from pci + virtio).
Could you respin the series, possibly including also Rob's patches,
addressing the issues which have been raised before?
Thanks!
