So a solution would be to pad and align the data structure to be a multiple of 16MiB or you could declare the backing dataport to be a 64MiB sized buffer and then cast it to be whatever you want in the C source code. E.g.
component Foo { dataport Buf(67108864) bar; }
We're going to be putting out a patch to be fixing this issue instead. The patch will change it so that instead of rounding up to a multiple of 4K all the time, it will be rounded up to a larger page size if the buffer's size is a multiple of that larger page size. Sincerely, Damon
