virtio/s390: size of SET_IND payload

2016-03-02T16:08:59+00:00

SET_IND takes as a payload the _address_ of the indicators, meaning that we have one of the rare cases where kmalloc(sizeof(&...)) is actually correct. Let's clarify that with a comment. The count for the ccw, however, was only correct because the indicators are 64 bit. Let's use the correct value.

virtio/s390: use dev_to_virtio

2016-03-02T16:08:58+00:00

Use dev_to_virtio() instead of open-coding it. Signed-off-by: Geliang Tang Message-Id: <912bf59bd3a48f2d4d4994681e898dc084fe29d3.1451484163.git.geliangtang@163.com> Signed-off-by: Cornelia Huck Signed-off-by: Michael S. Tsirkin

virtio: make find_vqs() checkpatch.pl-friendly

2016-01-12T18:47:06+00:00

checkpatch.pl wants arrays of strings declared as follows: static const char * const names[] = { "vq-1", "vq-2", "vq-3" }; Currently the find_vqs() function takes a const char *names[] argument so passing checkpatch.pl's const char * const names[] results in a compiler error due to losing the second const. This patch adjusts the find_vqs() prototype and updates all virtio transports. This makes it possible for virtio_balloon.c, virtio_input.c, virtgpu_kms.c, and virtio_rpmsg_bus.c to use the checkpatch.pl-friendly type. Signed-off-by: Stefan Hajnoczi Signed-off-by: Michael S.

virtio/s390: handle error values in irb

2015-12-17T08:37:33+00:00

The common I/O layer may pass an error value as the irb in the device's interrupt handler (for classic channel I/O). This won't happen in current virtio-ccw implementations, but it's better to be safe than sorry. Let's just return the error conveyed by the irb and clear any possible pending I/O indications.

s390/diag: add a statistic for diagnose calls

Introduce /sys/debug/kernel/diag_stat with a statistic how many diagnose calls have been done by each CPU in the system. Signed-off-by: Martin Schwidefsky

virtio/s390: handle failures of READ_VQ_CONF ccw

2015-09-16T09:48:08+00:00

In virtio_ccw_read_vq_conf() the return value of ccw_io_helper() was not checked. If the configuration could not be read properly, we'd wrongly assume a queue size of 0. Let's propagate any I/O error to virtio_ccw_setup_vq() so it may properly fail. Signed-off-by: Pierre Morel Signed-off-by: Cornelia Huck Signed-off-by: Michael S. Tsirkin
