Subject: [kvm-unit-tests PATCH v4 0/6] s390x: STFLE nested interpretation
Date: Wed, 16 Oct 2024 20:03:11 +0200 [thread overview]
Message-ID: <20241016180320.686132-1-nsg@linux.ibm.com> (raw)
v3 -> v4:
* pick up R-b's (thanks Claudio, Janosch, Nick)
* move diag intercept functions into sie-icpt.[hc]
expose some more functionality to avoid interpreting the diag text
with bit operations
* move snippet exit functions into snippet-exit.h,
guest part in s390x/snippet/lib
* add barrier before snippet exit
* simplify test (host and guest), add skip message
Add a test case that tests the interpretation of STFLE performed by a
nested guest using a snippet.
Also add some functionality to s390x lib, namely:
* exit (optionally with return code) from snippet
* add function for checking diag intercepts, replacing pv_icptdata_check_diag
v2 -> v3:
* pick up Ack (thanks Andrew)
* minor cosmetic change to rand generator
* add sie_is_pv function
* extend sie_is_diag_icpt to support pv, replace pv_icptdata_check_diag
v1 -> v2:
* implement SHA-256 based PRNG
* pick up R-b (thanks Claudio)
* change snippet exit API and implementation (thanks Claudio)
* add stfle-sie to unittests.cfg
Nina Schoetterl-Glausch (6):
s390x: lib: Remove double include
s390x: Add sie_is_pv
s390x: Add function for checking diagnose intercepts
s390x: Add library functions for exiting from snippet
s390x: Use library functions for snippet exit
s390x: Add test for STFLE interpretive execution (format-0)
