To go from the VSC accelerator buffer to an xrt:bo use the following code:
xrt::bo vpp::sc::get_xrt_bo(void* buf);Tip: Be aware though that the lifetime of
such a buffer will be fully controlled by the VSC runtime layer. The lifetime of a VSC
buffer starts from the time it gets allocated in an iteration of the
send_while loop, using vpp_acc::alloc_buf, until the end of the corresponding receive_all iteration.For example:
Acc::send_while([=]()->bool {
auto* Abuf = Acc::alloc_buf(Abp, size);
xrt::bo Abo = vpp::sc::get_xrt_bo(Abuf);
auto run = xo_kernel(Abo, ...);
run.wait();
...
