Allow more host memory channels for Blackhole #93

Open pjanevskiTT opened 1 month ago

pjanevskiTT commented 1 month ago

We should allow more than one host memory channel for Blackhole. Since we are considering moving to IOMMU (#49), this issue should be low prirority, unless tt-metal really needs it for Blackhole

For reference, we are forcing single host memory channel here https://github.com/tenstorrent/tt-umd/blob/main/device/tt_silicon_driver.cpp#L519

Metal uses multiple host memory channels to support fast-dispatch on multiple chips
