[PATCH 0/2] hw/riscv: Make s-mode IMSIC stride explicit

Posted by Joel Stanley 1 month ago

This adds s_imsic_stride to riscv_create_aia so machines can separate
the s-mode IMSIC layout from the guest count. They are related but the
layout isn't necessarily defined by the guest count. Doing this means
we can fix a bug that was in the Atlantis machine that I wrote.
