Currently when a PCI instruction returns a non-zero condition code it can be very hard to tell from the s390dbf logs what kind of instruction was executed. In case of PCI memory I/O (MIO) instructions it is even impossible to tell if we attempted a load, store or block store or how large the access was because only the address is logged. Improve this by adding an indicator byte for the instruction type to the error record and also store the length of the access for MIO instructions where this can not be deduced from the request. We use the following indicator values: - 'l': PCI load - 's': PCI store - 'b': PCI store block - 'L': PCI load (MIO) - 'S': PCI store (MIO) - 'B': PCI store block (MIO) - 'M': MPCIFC - 'R': RPCIT Reviewed-by: Matthew Rosato <mjrosato@linux.ibm.com> Reviewed-by: Pierre Morel <pmorel@linux.ibm.com> Signed-off-by: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by: Heiko Carstens <hca@linux.ibm.com>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
