It's admittedly a bit of a niche optimization, but is there any call that crosses bus_space_read_region_* (or bus_space_read_multi_* or various other calls) with copyout, or copyin with bus_space_write_region_* (or etc)? That is, I'd like to copy more or less directly between userland memory and bus-space mapped space, rather than having an additional copy into a kernel-space buffer in between.
I didn't see any way to do this when looking at the 8.0 bus-space manpages. I'm wondering if I missed something, or it's available via some other mechanism, or it's not currently supported, or what. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
