[PATCH v2 09/15] hw/riscv/riscv-iommu: add s-stage and g-stage support |
|
Date: |
Thu, 7 Mar 2024 13:03:12 -0300 |
From: Tomasz Jeznach <tjeznach@rivosinc.com>
Add support for s-stage (sv32, sv39, sv48, sv57 caps) and g-stage
(sv32x4, sv39x4, sv48x4, sv57x4 caps). Most of the work is done in the
riscv_iommu_spa_fetch() function that now has to consider how many
translation stages we need to walk the page table.
