So it can be safety accessed from multiple threads.
This variable type needs to be changed to unsigned long since
32-bit host platforms lack the necessary addition atomics on 64-bit
variables.
Using 32-bit counters on 32-bit host platforms should not be a problem
in practice since they can't realistically address more memory anyway.
Is it useful to have VFIO on 32-bit host platforms ?
If not, VFIO PCI should depend on (AARCH64 || PPC64 || X86_64) and we
could drop this patch. Let's address that independently.
Not sure how much use VFIO gets on 32-bit host platforms,
however totally disabling it on these would be a major functional regression -
at least if taken at its face value.
32-bit host platform support is being deprecated in QEMU 10.0 and should
be removed in QEMU 10.2.
Especially considering that making it work on 32-bit platform requires
just this tiny variable type change here.
yes. It raised my attention because x86 32-bit was the only host platform
I was not sure about and Alex confirmed it worked. We should simply wait
for removal.
Thanks,
