Provides a sysfs interface to view the AP matrix configured for the mediated matrix device. The relevant sysfs structures are: /sys/devices/vfio_ap/matrix/ ...... [mdev_supported_types] ......... [vfio_ap-passthrough] ............ [devices] ...............[$uuid] .................. matrix To view the matrix configured for the mediated matrix device, print the matrix file: cat matrix Below are examples of the output from the above command: Example 1: Adapters and domains assigned Assignments: Adapters 5 and 6 Domains 4 and 71 (0x47) Output 05.0004 05.0047 06.0004 06.0047 Examples 2: Only adapters assigned Assignments: Adapters 5 and 6 Output: 05. 06. Examples 3: Only domains assigned Assignments: Domains 4 and 71 (0x47) Output: .0004 .0047 Signed-off-by: Tony Krowiak <akrowiak@linux.ibm.com> Reviewed-by: Halil Pasic <pasic@linux.ibm.com> Reviewed-by: Cornelia Huck <cohuck@redhat.com> Tested-by: Michael Mueller <mimu@linux.ibm.com> Tested-by: Farhan Ali <alifm@linux.ibm.com> Tested-by: Pierre Morel <pmorel@linux.ibm.com> Message-Id: <20180925231641.4954-10-akrowiak@linux.vnet.ibm.com> Signed-off-by: Christian Borntraeger <borntraeger@de.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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
