2019-04-25misc: genwqe: Fix misuse of %xFuqian Huang
The pointer should be printed with %p or %px rather than cast to long long type and printed with %016llx. Change %x to %p to print the pointer. Signed-off-by: Fuqian Huang <huangfq.daxian@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-12-06misc: remove GENWQE_DEBUGFS_RO()Yangtao Li
We already have the DEFINE_SHOW_ATTRIBUTE.There is no need to define such a macro,so remove GENWQE_DEBUGFS_RO.Also use DEFINE_SHOW_ATTRIBUTE to simplify some code. Signed-off-by: Yangtao Li <tiny.windzz@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2018-07-03misc: genwqe: remove several redundant variablesColin Ian King
The variables val16, type, pci_dev and type are set but are never used hence they are redundant and can be removed. Cleans up clang warnings: warning: variable 'type' set but not used [-Wunused-but-set-variable] warning: variable 'val16' set but not used [-Wunused-but-set-variable] warning: variable 'pci_dev' set but not used [-Wunused-but-set-variable] warning: variable 'type' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-12-19genwqe: Make defines uppercaseGuilherme G. Piccoli
This is a clean-up patch, no functional changes intended. It makes all defines uppercase, following a "tradition" that helps to make code clearer. Signed-off-by: Guilherme G. Piccoli <gpiccoli@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2014-09-23GenWQE: Support blocking when DDCB queue is busyFrank Haverkamp
When the GenWQE hardware queue was busy, the driver returned simply -EBUSY. This caused polling by applications which increased the load on the already busy system. This change implements the possiblity to sleep on a waitqueue instead when the DDCB queue is busy. The requestor is woken up when there is free space on the queue again. The old way to get -EBUSY is still available if the device is openend with O_NONBLOCKING. The default is now blocking behavior.

2014-09-23GenWQE: Remove sysfs entry for driver versionFrank Haverkamp
A special sysfs entry to display the driver version is not needed. We left the driver version and adjusted it to the naming a lot of other drivers use. The information can be retrieved by using modinfo genwqe_card. modinfo genwqe_card will provide the same information.

2014-07-09GenWQE: Add support for EEH error recoveryKleber Sacilotto de Souza
This patch implements the callbacks and functions necessary to have EEH recovery support. It adds a config option to enable or disable explicit calls to trigger platform specific mechanisms on error recovery paths. This option is enabled by default only on PPC64 systems and can be overritten via debugfs. If this option is enabled, on the error recovery path the driver will call pci_channel_offline() to check for error condition and issue non-raw MMIO reads to trigger early EEH detection in case of hardware failures. This is necessary since the driver MMIO helper funtions use raw accessors.

2014-02-07drivers/misc: delete non-required instances of include <linux/init.h>Paul Gortmaker
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.
