Hi,

I'm looking for a way to access 64 or 128 bit of device space in a single access. For smaller accesses I use ioread32() and friends. But which way should I do it for the next bigger accesses? Casting the iospace to something like u64* looks very suspicious to me. Any better ideas?

Greetings,

Eike

There's no portable way to do this as far as I'm aware, for the likely reason that on many architectures it's impossible to do it in one access..
