The latter is +the default behaviour on which virtfs 9p expects only one device to be +shared with the same export, and if more than one device is shared and +accessed via the same 9p export then only a warning message is logged +(once) by qemu on host side. In order to avoid file ID collisions on guest +you should either create a separate virtfs export for each device to be +shared with guests (recommended way) or you might use "remap" instead which +allows you to share multiple devices with only one export instead, which is +achieved by remapping the original inode numbers from host to guest in a +way that would prevent such collisions. Remapping inodes in such use cases +is required because the original device IDs from host are never passed and +exposed on guest. Instead all files of an export shared with virtfs always +share the same device id on guest. So two files with identical inode +numbers but from actually different devices on host would otherwise cause a +file ID collision and hence potential misbehaviours on guest. "forbid" on +the other hand assumes like "warn" that only one device is shared by the +same export, however it will not only log a warning message but also +deny access to additional devices on guest. Note though that "forbid" does +currently not block all possible file access operations (e.g. readdir() +would still return entries from other devices). @end table ETEXI diff --git a/target/s390x/cc_helper.c b/target/s390x/cc_helper.c index cf68792733..44731e4a85 100644 --- a/target/s390x/cc_helper.c +++ b/target/s390x/cc_helper.c @@ -21,6 +21,7 @@ #include "qemu/osdep.h" #include "cpu.h" #include "internal.h" +#include "tcg_s390x.h" #include "exec/exec-all.h" #include "exec/helper-proto.h" #include "qemu/host-utils.h" @@ -588,8 +589,7 @@ void HELPER(sacf)(CPUS390XState *env, uint64_t a1) break; default: HELPER_LOG("unknown sacf mode: %" PRIx64 "\n", a1); - s390_program_interrupt(env, PGM_SPECIFICATION, 2, GETPC()); - break; + tcg_s390_program_interrupt(env, PGM_SPECIFICATION, GETPC()); } } #endif diff --git a/target/s390x/cpu.h b/target/s390x/cpu.h index 163dae13d7..17460ed7b3 100644 --- a/target/s390x/cpu.h +++ b/target/s390x/cpu.h @@ -1,6 +1,10 @@ /* * S/390 virtual CPU header * + * For details on the s390x architecture and used definitions (e.g., + * PSW, PER and DAT (Dynamic Address Translation)), please refer to + * the "z/Architecture Principles of Operations" - a.k.a.
