Hi there,
I order to develop a qemu module, I aim to use the PCI CAS (compare and
swap) function
to guarantee an atomic access somewhere in the guest memory (in a
multi-core emulation case).
Nevertheless, I did not find any routine in qemu implementing this function.
Could anyone on this lis
Hi Max,
thank you for your answer. Actually, I hadn't confused.
I already thought to your proposal but I found that it was a really ugly
solution (essentially because of the uint32_t to uint64_t silent
conversion).
Isn't there any other (current or future) development that may fix it ?
Hi there,
I've read a few days ago that it was possible to emulate PCI device
with 64-bit BARs and have a real 64-bit memory access.
Thus, I've created a virtual device named toto accessible through a
64-bit BAR
