When we try to recover a PCI function using echo 1 > /sys/bus/pci/devices/<id>/recover or manually with echo 1 > /sys/bus/pci/devices/<id>/remove echo 0 > /sys/bus/pci/slots/<slot>/power echo 1 > /sys/bus/pci/slots/<slot>/power clp_disable_fn() / clp_enable_fn() call clp_set_pci_fn() to first disable and then reenable the function. When the function is already in the requested state we may be left with an invalid function handle. To get a new valid handle we do a clp_list_pci() call. For this we need both the function ID and function handle in clp_set_pci_fn() so pass the zdev and get both. To simplify things also pull setting the refreshed function handle into clp_set_pci_fn() Signed-off-by: Niklas Schnelle <schnelle@linux.ibm.com> Reviewed-by: Peter Oberparleiter <oberpar@linux.ibm.com> Signed-off-by: Vasily Gorbik <gor@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.
