Subject: [Qemu-devel] [PATCH v1 0/9] tcg: probe_write() refactorings and watchpoints
Date: Fri, 23 Aug 2019 12:07:32 +0200 [thread overview]
Message-ID: <20190823100741.9621-1-david@redhat.com> (raw)
Fix and refactore some things around probe_write() in s390x code. Introduce
probe_write() for CONFIG_USER_ONLY. Finally, prepare the watchpoint logic
for being called from probe_write() and add the call.
This is the first step of some changes necessary to handle fault-safe
access accross multiple pages on s390x. The next step is making
probe_write() return an address, similar to tlb_vaddr_to_host(), and
introduing probe_read().
