2018-11-14tests/tcg/multiarch: fix 32bit linux-test on 64bit hostLaurent Vivier1-2/+2
Fix: TEST linux-test on i386 .../tests/tcg/multiarch/linux-test.c:201: readdir readdir() calls getdents64() to have the list of the entries in a directory, and getdents64() can return 64bit d_off values (with ext4, for instance) that will not fit in the 32bit d_off field of the readdir() dirent structure. To avoid that, use readdir64() to use a 64bit d_off field too. Signed-off-by: Laurent Vivier <laurent@vivier.eu> Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

2018-08-28target/s390x: fix PACK reading 1 byte less and writing 1 byte morePavel Zbitskiy2-0/+22
PACK fails on the test from the Principles of Operation: F1F2F3F4 becomes 0000234C instead of 0001234C due to an off-by-one error. Furthermore, it overwrites one extra byte to the left of F1. If len_dest is 0, then we only want to flip the 1st byte and never loop over the rest. Therefore, the loop condition should be > and not >=. If len_src is 1, then we should flip the 1st byte and pack the 2nd. Since len_src is already decremented before the loop, the first condition should be >=, and not >. Likewise for len_src == 2 and the second condition.

Suppose psw.mask=0x0000000080000000, cc=2, r1=0 and we do "ipm 1". This command must touch only bits 32-39, so the expected output is r1=0x20000000.

2018-08-28target/s390x: fix CSST decoding and runtime alignment checkPavel Zbitskiy2-0/+44
CSST is defined as: C(0xc802, CSST, SSF, CASS, la1, a2, 0, 0, csst, 0) It means that the first parameter is handled by in1_la1(). in1_la1() fills addr1 field, and not in1. Furthermore, when extract32() is used for the alignment check, the third parameter should specify the number of trailing bits that must be 0. For FC these numbers are: FC=0 (word, 4 bytes): 2 FC=1 (double word, 8 bytes): 3 FC=2 (quad word, 16 bytes): 4 For SC these numbers correspond to the size: SC=0: 0 SC=1: 1 SC=2: 2 SC=3: 3 SC=4: 4 Signed-off-by: Pavel Zbitskiy <pavel.zbitskiy@gmail.com> Message-Id: <20180821025104.19604-4-pavel.zbitskiy@gmail.com> Reviewed-by: David Hildenbrand <david@redhat.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>

2018-06-20tests: add top-level make dependency for docker buildsAlex Bennée1-0/+31
One problem with satisfying your docker dependencies in a sub-make it you might end up trying to satisfy the dependency multiple times. This is especially a problem with debian-sid based cross compilers and CI setups. We solve this by doing a docker build pass at the top level before any sub-makes are called. We still need to satisfy dependencies in the Makefile.target call so people can run tests from individual target directories. We introduce a new Makefile.probe which gets called for each PROBE_TARGET and allows us to build up the list. It does require multiply including config-target.mak which shouldn't cause any issues as it shouldn't define anything that clashes with config-host.mak. However we undefine a few key variables each time around. Signed-off-by: Alex Bennée <alex.bennee@linaro.org>

2018-06-20tests/tcg/Makefile: update to be called from Makefile.targetAlex Bennée1-107/+76
This make is now invoked from each individual target make with the appropriate CC and EXTRA_CFLAGS set for each guest. It then includes additional Makefile.targets from: - tests/tcg/multiarch (always) - tests/tcg/$(TARGET_BASE_ARCH) (if available) - tests/tcg/$(TARGET_NAME) The order is important as the later Makefile's may want to suppress TESTS from its base arch profile. Each included Makefile.target is responsible for adding TESTS as well as defining any special build instructions for individual tests.
