Hello CRIU mailing list,
This set of patches (version 3) adds the s390x (64 bit mainframe) backend
support to the CRIU checkpoint/restore tool.
The patches apply to the "criu-dev" branch on top of commit 843761066071cf
("criu/pie/parasite-vdso: Handle also systems without VVAR").
The patches are also available in the "ibm_criu-dev-v3" branch under:
* https://github.com/michael-holzheu/criu/tree/ibm_criu-dev-v3
Travis run for this branch:
* https://travis-ci.org/michael-holzheu/criu/builds/248889146
Patch set history
-----------------
v2->v3:
* Squash patches for issues found in v2 review:
- s390: Consolidate -msoft-float into Makefile.compel
- Fix ARCH check for -msoft-float in Makefiles
- Fix big endian byte order checks
* Remove patch (because already upstream):
- criu/pie/parasite-vdso: Handle also systems without VVAR
* Add Dimitry's Reviewed-by tags (thanks for that)
v1->v2:
* Split first monster patch into more parts as suggested by Mike Rapoport
* Fix toplevel Makefile patch damage
Patch set description
---------------------
The s390x platform is is a 64 bit big endian CISC architecture.
This patch set does not include:
* Support for 31 bit compat tasks
* Support for processes that use s390 runtime instrumentation
Some parts of the patch have been contributed by:
* Alice Frosi <alice@xxxxxxxxxxxxxxxxxx>
On s390 all tests of the zdtm testsuite succeed on Ubuntu 16.04 with kernel
4.8.0-34-generic execpt for the following:
- zdtm/static/del_standalone_un
- zdtm/static/deleted_unix_sock
- zdtm/static/mnt_ext_dev
- zdtm/static/overmount_dev
- zdtm/static/overmount_fifo
- zdtm/static/overmount_file
- zdtm/static/overmount_sock
- zdtm/static/pthread02
- zdtm/static/ptrace_sig
- zdtm/static/tempfs_overmounted
- zdtm/static/unlink_fstat01+
- zdtm/static/unlink_largefile
- zdtm/static/unlink_regular00
- zdtm/static/vfork00
- zdtm/transition/thread-bomb
We have not analyzed the failures yet because for us those tests also failed on
Ubuntu for x86_64.
Best Regards,
Michael
