[Qemu-devel] [PATCH v2 0/2] tcg: Introduce probe_access() and return a host pointer

Posted by David Hildenbrand 4 years, 7 months ago

Let's return a host pointer from probe_access() if possible and provide
probe_access(). s390x will soon make use of probe_access() and use the
provided host pointer.

v1 -> v2:
- Rebased to tcg-next
- "tcg: Make probe_write() return a pointer to the host page"
-- Rephrase documentation
- "tcg: Factor out probe_write() logic into probe_access()"
-- Don't check the MMU index
