unfortunately cherry-picking the SeaBIOS 1.10 binary update commit from
qemu master (6e99f5741ff1) on top of v2.7.0 does not solve the issue

Ladi Prosek (2):

As the userspace vitio driver became popular, more and more request

Why not?

Hi Alex,
I have a merged branch with these changes but it needs more work. I
will post the next version soon(for some definition of soon :)
You can find the in-progress branch here:

Thanks,

When only offset is specified but no size and the offset is greater than
the real size of the containing device an overflow occurs when parsing
the options. This overflow is harmless because we do check for this
exact situation little bit later, but it leads to an error message with
weird values. I
We make sure that the size is aligned to sector length to prevent any
round ups. Otherwise we could end up reading/writing data outside the
area specified by user. This is only needed when user supplies the size
option to avoid any surprises. It is not necessary when only offset is
set.

The patch set contains two patches related to the use of 'offset' option:
- The first patch is purely cosmetic. Although it touches overflow
check it only affects what error message is produced.
- Second patch lessens the restriction on the size alignment when only
'offset' is specified.
Implement real atomic tas:
When (Rn) = 0, 1 -> T
Otherwise, 0 -> T
In both cases, 1 -> MSB of (Rn)
using atomic_fetch_or_i32() and setcondi_i32().
