s390/sclp: Remove SCLP_OFB Kconfig option

2026-04-28T12:45:02+00:00

Remove the SCLP_OFB Kconfig option and enable the guarded code unconditionally. This guards only a few lines of code, so the impact is very low while at the same time this reduces the large number of Kconfig options.

s390/tape: Consolidate tape config options and modules

2026-02-05T12:02:48+00:00

The tape device driver only supports 3490E devices on Virtual Tape Server (VTS). There is no point in keeping separated options and modules for different device types and general hardware support. Consolidate the tape config option into a single option, which enables the complete tape support with one singular module called 'tape_s390'. The corresponding module entry points are adapted and consolidate in tape_init() and tape_exit() respectively in tape_core.c The current module author and descriptions of the individual tape modules are outdated and haven't been changed for quite some time. Change it to a more generic description that is in line with the corresponding supported s390 architecture for the single tape module. Signed-off-by: Jan Höppner Signed-off-by: Heiko Carstens

s390/tape: Rename tape_34xx.c to tape_3490.c

2026-02-04T07:31:30+00:00

The driver now exclusively supports 3490 tape devices, given support for 3480 tape devices has been removed. Update the device driver name, its source file name, and change any occurrences of "34xx/34XX" to "3490" in the source code and comments.

s390/tape: Remove 3480 tape device type

2026-02-04T07:31:30+00:00

The only supported device type by the Virtual Tape Server is 3490. The 3480 device type was an old physical tape model and doesn't exist anymore. Remove 3480 from the list and any mention of it. Signed-off-by: Jan Höppner Reviewed-by: Jens Remus Signed-off-by: Heiko Carstens

s390/tape: Remove support for 3590/3592 models

2026-02-04T07:31:29+00:00

Physical 3590/3592 tape models are not supported anymore for a very long time. The Virtual Tape Server (VTS) emulates and presents only 3490E models to the host. This is the only supported model and storage server. Remove the entire code base for 3590/3592 models as it can be considered dead code for quite some time already.

s390: Remove protvirt and kvm config guards for uv code

2024-07-23T14:02:33+00:00

Removing the CONFIG_PROTECTED_VIRTUALIZATION_GUEST ifdefs and config option as well as CONFIG_KVM ifdefs in uv files. Having this configurable has been more of a pain than a help. It's time to remove the ifdefs and the config option. Signed-off-by: Janosch Frank Acked-by: Christian Borntraeger Acked-by: Heiko Carstens Signed-off-by: Vasily Gorbik

s390/uvdevice: Add info IOCTL

2023-06-16T09:08:09+00:00

Add an IOCTL that allows userspace to find out which IOCTLs the uvdevice supports without trial and error. Explicitly expose the IOCTL nr for the request types.
