2015-07-07	virtio/s390: rename drivers/s390/kvm -> drivers/s390/virtio	Cornelia Huck	1	-1/+1
	This more accurately reflects what these drivers actually do. Suggested-by: Paolo Bonzini <pbonzini@redhat.com> Acked-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2009-03-26	[S390] split/move machine check handler code	Heiko Carstens	1	-1/+0
	Split machine check handler code and move it to cio and kernel code where it belongs to. No functional change. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-03-26	[S390] move sysinfo.c from drivers/s390 to arch/s390/kernel	Heiko Carstens	1	-3/+1
	All in sysinfo.c is core kernel code and not driver code. So move it to arch/s390/kernel. Also includes some small cleanups. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-01-06	s390: remove s390_root_dev_*()	Mark McLoughlin	1	-1/+1
	Replace s390_root_dev_register() with root_device_register() etc. [Includes fix from Cornelia Huck] Signed-off-by: Mark McLoughlin <markmc@redhat.com> Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-04-27	s390: KVM guest: virtio device support, and kvm hypercalls	Christian Borntraeger	1	-1/+1
	This patch implements kvm guest kernel support for paravirtualized devices and contains two parts: o a basic virtio stub using virtio_ring and external interrupts and hypercalls o full hypercall implementation in kvm_para.h Currently we dont have PCI on s390. Making virtio_pci usable for s390 seems more complicated that providing an own stub. This virtio stub is similar to the lguest one, the memory for the descriptors and the device detection is made via additional mapped memory on top of the guest storage. We use an external interrupt with extint code 0x2603 for host->guest notification. The hypercall definition uses the diag instruction for issuing a hypercall. The parameters are written in R2-R7, the hypercall number is written in R1. This is similar to the system call ABI (svc) which can use R1 for the number and R2-R6 for the parameters.

2007-02-05	[S390] Calibrate delay and bogomips.	Martin Schwidefsky	1	-0/+2
	Preset the bogomips number to the cpu capacity value reported by store system information in SYSIB 1.2.2. This value is constant for a particular machine model and can be used to determine relative performance differences between machines. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2006-01-06	[PATCH] s390: move s390_root_dev_* out of the cio layer	Carsten Otte	1	-1/+1
	Extract the s390_root_dev_* functions from the common I/O layer as they are also used by non-ccw device drivers.

2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+9
	Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
