s390: Remove KMSG_COMPONENT macro

2025-11-24T10:45:21Z

The KMSG_COMPONENT macro is a leftover of the s390 specific "kernel message catalog" which never made it upstream. Remove the macro in order to get rid of a pointless indirection. Replace all users with the string it defines. In almost all cases this leads to a simple replacement like this: - #define KMSG_COMPONENT "appldata" - #define pr_fmt(fmt) KMSG_COMPONENT ": " fmt + #define pr_fmt(fmt) "appldata: " fmt Except for some special cases this is just mechanical/scripted work.

s390/qeth: Make hw_trap sysfs attribute idempotent

2025-07-22T00:46:13Z

Update qeth driver to allow writing an existing value to the "hw_trap" sysfs attribute. Attempting such a write earlier resulted in -EINVAL. In other words, make the sysfs attribute idempotent. After: $ cat hw_trap disarm $ echo disarm > hw_trap $ Suggested-by: Alexandra Winter Signed-off-by: Aswin Karuvally Reviewed-by: Alexandra Winter Signed-off-by: Alexandra Winter Reviewed-by: Simon Horman Link: https://patch.msgid.link/20250718141711.1141049-1-wintera@linux.ibm.com Signed-off-by: Jakub Kicinski

s390/qeth: Convert sysfs sprintf to sysfs_emit

2023-02-11T03:49:53Z

Following the advice of the Documentation/filesystems/sysfs.rst. All sysfs related show()-functions should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.

s390/qeth: remove OSN support

2021-07-20T13:17:06Z

Commit fb64de1bc36c ("s390/qeth: phase out OSN support") spelled out why the OSN support in qeth is in a bad shape, and put any remaining interested parties on notice to speak up before it gets ripped out. It's 2021 now, so make true on that promise and remove all the OSN-specific parts from qeth. This also means that we no longer need to export various parts of the cmd & data path internals to the L2 driver. Signed-off-by: Julian Wiedmann Reviewed-by: Alexandra Winter Signed-off-by: David S.

s390/qeth: clean up load/remove code for disciplines

2021-01-29T04:35:57Z

We have two usage patterns: 1. get & ->setup() a new discipline, or 2. ->remove() & put the currently loaded one. Add corresponding helpers that hide the internals & error handling.

s390/qeth: use dev->groups for common sysfs attributes

2020-12-07T14:55:21Z

All qeth devices have a minimum set of sysfs attributes, and non-OSN devices share a group of additional attributes. Depending on whether the device is forced to use a specific discipline, the device_type then specifies further attributes. Shift the common attributes into dev->groups, so that the device_type only contains the discipline-specific attributes. This avoids exposing the common attributes to the disciplines, and nicely cleans up our sysfs code. While replacing the qeth_l*_*_device_attributes() helpers, switch from sysfs_*_groups() to the more generic device_*_groups(). Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

s390/qeth: use netdev_name()

2020-10-02T23:22:49Z

Replace our custom version of netdev_name(). Once we started to allocate the netdev at probe time with commit d3d1b205e89f ("s390/qeth: allocate netdevice early"), this stopped working as intended anyway. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

s390/qeth: allow configuration of TX queues for OSA devices

2020-10-02T23:22:49Z

For OSA devices that are _not_ configured in prio-queue mode, give users the option of selecting the number of active TX queues. This requires setting up the HW queues with a reasonable default QoS value in the QIB's PQUE parm area. As with the other device types, we bring up the device with a minimal number of TX queues for compatibility reasons. Signed-off-by: Julian Wiedmann Signed-off-by: David S. Miller

s390/qeth: replace deprecated simple_stroul()

2020-09-23T19:07:54Z

Convert the remaining occurences in sysfs code to kstrtouint(). While at it move some input parsing out of locked sections, replace an open-coded clamp() and remove some unnecessary run-time checks for ipatoe->mask_bits that are already enforced when creating the object.
