2023-07-03s390: include linux/io.h instead of asm/io.hHeiko Carstens
Include linux/io.h instead of asm/io.h everywhere. linux/io.h includes asm/io.h, so this shouldn't cause any problems. Instead this might help for some randconfig build errors which were reported due to some undefined io related functions. Also move the changed include so it stays grouped together with other includes from the same directory. For ctcm_mpc.c also remove not needed comments (actually questions).

2023-06-23s390/ctcm: Convert sprintf/snprintf to scnprintfThorsten Winkler
This LWN article explains the why scnprintf is preferred over snprintf in general https://lwn.net/Articles/69419/ Ie. snprintf() returns what *would* be the resulting length, while scnprintf() returns the actual length. Note that ctcm_print_statistics() writes the data into the kernel log and is therefore not suitable for sysfs_emit(). Observable behavior is not changed, as there may be dependencies.

2023-06-15s390/ism: Fix trying to free already-freed IRQ by repeated ism_dev_exit()Julian Ruess
This patch prevents the system from crashing when unloading the ISM module. How to reproduce: Attach an ISM device and execute 'rmmod ism'. Error-Log: - Trying to free already-free IRQ 0 - WARNING: CPU: 1 PID: 966 at kernel/irq/manage.c:1890 free_irq+0x140/0x540 After calling ism_dev_exit() for each ISM device in the exit routine, pci_unregister_driver() will execute ism_remove() for each ISM device. Because ism_remove() also calls ism_dev_exit(), free_irq(pci_irq_vector(pdev, 0), ism) is called twice for each ISM device. This results in a crash with the error 'Trying to free already-free IRQ'. In the exit routine, it is enough to call pci_unregister_driver() because it ensures that ism_dev_exit() is called once per ISM device.

2023-05-25s390/ism: Set DMA coherent maskNiklas Schnelle
A future change will convert the DMA API implementation from the architecture specific arch/s390/pci/pci_dma.c to using the common code drivers/iommu/dma-iommu.c which the utilizes the same IOMMU hardware through the s390-iommu driver. Unlike the s390 specific DMA API this requires devices to correctly set the coherent mask to be allowed to use IOVAs >2^32 in dma_alloc_coherent(). This was however not done for ISM devices. ISM requires such addresses since currently the DMA aperture for PCI devices starts at 2^32 and all calls to dma_alloc_coherent() would thus fail.

2023-01-25s390/ism: Introduce struct ism_dmbStefan Raspl
Conceptually, a DMB is a structure that belongs to ISM devices. However, SMC currently 'owns' this structure. So future exploiters of ISM devices would be forced to include SMC headers to work - which is just weird. Therefore, we switch ISM to struct ism_dmb, introduce a new public header with the definition (will be populated with further API calls later on), and, add a thin wrapper to please SMC. Since structs smcd_dmb and ism_dmb are identical, we can simply convert between the two for now.

2022-08-08s390/qeth: cache link_info for ethtoolAlexandra Winter
Since commit e6e771b3d897 ("s390/qeth: detach netdevice while card is offline") there was a timing window during recovery, that qeth_query_card_info could be sent to the card, even before it was ready for it, leading to a failing card recovery. There is evidence that this window was hit, as not all callers of get_link_ksettings() check for netif_device_present. Use cached values in qeth_get_link_ksettings(), instead of calling qeth_query_card_info() and falling back to default values in case it fails. Link info is already updated when the card goes online, e.g. after STARTLAN (physical link up). Set the link info to default values, when the card goes offline or at STOPLAN (physical link down). A follow-on patch will improve values reported for link down.
