From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Pierre Morel Subject: [PATCH v3 0/1] s390: vfio_ap: link the vfio_ap devices to the vfio_ap bus subsystem Date: Thu, 21 Feb 2019 15:14:53 +0100 Message-Id: <1550758494-28227-1-git-send-email-pmorel@linux.ibm.com> Sender: linux-kernel-owner@vger.kernel.org List-Archive: List-Post: To: borntraeger@de.ibm.com Cc: cohuck@redhat.com, linux-kernel@vger.kernel.org, linux-s390@vger.kernel.org, frankja@linux.ibm.com, akrowiak@linux.ibm.com, pasic@linux.ibm.com, david@redhat.com, schwidefsky@de.ibm.com, heiko.carstens@de.ibm.com, freude@linux.ibm.com List-ID: The goal of this patch is to standardize the device-driver interface for the VFIO_AP ap_matrix_device to satisfy user-land tools working on hot-plug (UDEV/LIBVIRT). Christian Borntraeger reported libvirt looping when a matrix device was available before the libvirt start. Marc Hartmayer debugged this and circumvented this in libvirt: https://www.redhat.com/archives/libvir-list/2019-February/msg00837.html Pierre Morel (1): s390: vfio_ap: link the vfio_ap devices to the vfio_ap bus subsystem drivers/s390/crypto/vfio_ap_drv.c | 44 ++++++++++++++++++++++++++++------- drivers/s390/crypto/vfio_ap_ops.c | 4 ++-- drivers/s390/crypto/vfio_ap_private.h | 1 + 3 files changed, 38 insertions(+), 11 deletions(-) -- 2.7.4
