[PATCH v2 0/3] hw/riscv/riscv-iommu.c: additional PTE checks

Posted by Daniel Henrique Barboza 3 weeks, 3 days ago

Hi,

I'm sending a v2 because I just ended up fixed another iommu bug that
happened to be in the same code, and it has a test dependency with patch
2.  Sending it standalone will cause conflicts so I'm adding it in the
batch.

Patches 1 and 2 didn't change.  R-bs from Chao and Nutty were added in
both.

Patches based on alistair/riscv-to-apply.next.


Changes from v1:
- patch 3 (new):
  - add another PTE_U fault that we're missing (gitlab 3555)
- v1 link: https://lore.kernel.org/qemu-devel/20260629121334.567587-1-daniel.barboza@oss.qualcomm.com/

Daniel Henrique Barboza (3):
  hw/riscv/riscv-iommu.c: check for reserved PTE bits
  hw/riscv/riscv-iommu.c: fault when !PTE_U and no priv access
  hw/riscv/riscv-iommu.c: fault for non-user PTE in G_STAGE
