[PATCH v4 0/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

[PATCH v4 0/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

[Janis Schoetterl-Glausch]

User space can use the MEM_OP ioctl to make storage key checked reads
and writes to the guest, however, it has no way of performing atomic,
key checked, accesses to the guest.
Extend the MEM_OP ioctl in order to allow for this, by adding a cmpxchg
mode. For now, support this mode for absolute accesses only.

This mode can be use, for example, to set the device-state-change
indicator and the adapter-local-summary indicator atomically.

Also contains some fixes/changes for the memop selftest independent of
the cmpxchg changes.

v3 -> v4
 * no functional change intended
 * rework documentation a bit
 * name extension cap cmpxchg bit
 * picked up R-b (thanks Thomas)
 * various changes (rename variable, comments, ...) see range-diff below

v2 -> v3
 * rebase onto the wip/cmpxchg_user_key branch in the s390 kernel repo
 * use __uint128_t instead of unsigned __int128
 * put moving of testlist into main into separate patch
 * pick up R-b's (thanks Nico)

v1 -> v2
 * get rid of xrk instruction for cmpxchg byte and short implementation
 * pass old parameter via pointer instead of in mem_op struct
 * indicate failure of cmpxchg due to wrong old value by special return
   code
 * picked up R-b's (thanks Thomas)

[PATCH v4 1/9] KVM: s390: Extend MEM_OP ioctl by storage key checked cmpxchg

[Janis Schoetterl-Glausch]

User space can use the MEM_OP ioctl to make storage key checked reads
and writes to the guest, however, it has no way of performing atomic,
key checked, accesses to the guest.
Extend the MEM_OP ioctl in order to allow for this, by adding a cmpxchg
mode. For now, support this mode for absolute accesses only.

This mode can be use, for example, to set the device-state-change
indicator and the adapter-local-summary indicator atomically.

[PATCH v4 2/9] Documentation: KVM: s390: Describe KVM_S390_MEMOP_F_CMPXCHG

[Janis Schoetterl-Glausch]

Describe the semantics of the new KVM_S390_MEMOP_F_CMPXCHG flag for
absolute vm write memops which allows user space to perform (storage key
checked) cmpxchg operations on guest memory.

+In this case, instead of doing an unconditional write, the access occurs
+only if the target location contains the value pointed to by "old_addr".
+This is performed as an atomic cmpxchg with the length specified by the "size"
+parameter. "size" must be a power of two up to and including 16.
+If the exchange did not take place because the target value doesn't match the
+old value, KVM_S390_MEMOP_R_NO_XCHG is returned.
+In this case the value "old_addr" points to is replaced by the target value.

[PATCH v4 5/9] KVM: s390: selftest: memop: Move testlist into main

[Janis Schoetterl-Glausch]

This allows checking if the necessary requirements for a test case are
met via an arbitrary expression. In particular, it is easy to check if
certain bits are set in the memop extension capability.

I'd maybe add a check for mop->op == KVM_S390_MEMOP_ABSOLUTE_WRITE here, 
since calling the _READ function with the F_CMPXCHG flag set does not make 
too much sense.

Anyway, patch looks good to me, so with or without that additional check:

Not sure what it is in this config that causes gcc to emit this symbol instead of a shift instruction, but casting old/new to 32 bit fixes
the error.
