Hi all, I forgot to write that some tests about addressing will fail if the following QEMU patch is not installed: Subject: [PATCH v1 0/1] s390x: css: report errors from ccw_dstream_read/write Date: Tue, 6 Apr 2021 09:44:12 +0200 Message-Id: <1617695053-7328-1-git-send-email-pmorel@linux.ibm.com> Regards, Pierre On 4/6/21 9:40 AM, Pierre Morel wrote: > The goal of this series is to test some of the I/O instructions, > SSCH, CSCH and HSCH for errors like invalid parameters, addressing, > timing etc. > We can not test the sending of an instruction before the last instruction > has been proceeded by QEMU due to the QEMU serialization but we can > check the behavior of an instruction if it is started before the status > of the last instruction is read. > > To do this we first separate the waiting for the interruption and the > checking of the IRB and enable the subchannel without an I/O ISC to > avoid interruptions at this subchannel and second, we add an argument > to the routine in charge to check the IRB representing the expected > SCSW control field of the IRB. > > We also need several other enhancements to the testing environment: > > - definitions for the SCSW control bits > - a new function to disable a subchannel > - a macro to simplify skiping tests when no device is present > (I know the warning about return in macro, can we accept it?) > > In the new tests we assume that all the test preparation is working and > use asserts for all function for which we do not expect a failure. > > regards, > Pierre > > PS: Sorry, I needed to modify patches 4 and 5 for which I already had RB or AB. > I removed them even I hope you will agree with my modifications. > > > Pierre Morel (16): > s390x: lib: css: disabling a subchannel > s390x: lib: css: SCSW bit definitions > s390x: css: simplify skipping tests on no device > s390x: lib: css: separate wait for IRQ and check I/O completion > s390x: lib: css: add SCSW ctrl expectations to check I/O completion > s390x: lib: css: checking I/O errors > s390x: css: testing ssch errors > s390x: css: ssch check for cpa zero > s390x: css: ssch with mis aligned ORB > s390x: css: ssch checking addressing errors > s390x: css: No support for MIDAW > s390x: css: Check ORB reserved bits > s390x: css: checking for CSS extensions > s390x: css: issuing SSCH when the channel is status pending > s390x: css: testing halt subchannel > s390x: css: testing clear subchannel > > lib/s390x/css.h | 42 ++++- > lib/s390x/css_lib.c | 138 ++++++++++++-- > s390x/css.c | 425 +++++++++++++++++++++++++++++++++++++++++--- > s390x/unittests.cfg | 8 +- > 4 files changed, 565 insertions(+), 48 deletions(-) >
The goal of this series is to test some of the I/O instructions, SSCH, CSCH and HSCH for errors like invalid parameters, addressing, timing etc. We can not test the sending of an instruction before the last instruction has been proceeded by QEMU due to the QEMU serialization but we can check the behavior of an instruction if it is started before the status of the last instruction is read. To do this we first separate the waiting for the interruption and the checking of the IRB and enable the subchannel without an I/O ISC to avoid interruptions at this subchannel and second, we add an argument to the routine in charge to check the IRB representing the expected SCSW control field of the IRB. We also need several other enhancements to the testing environment: - definitions for the SCSW control bits - a new function to disable a subchannel - a macro to simplify skiping tests when no device is present (I know the warning about return in macro, can we accept it?) In the new tests we assume that all the test preparation is working and use asserts for all function for which we do not expect a failure. regards, Pierre PS: Sorry, I needed to modify patches 4 and 5 for which I already had RB or AB. I removed them even I hope you will agree with my modifications.
