2013-04-26Utilize selective runtime reg sync for hot code pathsJason J. Herne1-3/+12
Make use of new kvm_s390_get_registers_partial() for kvm_handle_css_inst() and handle_hypercall() since they only need registers from the partial set and they are called quite frequently. Signed-off-by: Jason J. Herne <jjherne@us.ibm.com> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-04-26Allow selective runtime register synchronizationJason J. Herne2-0/+84
We want to avoid expensive register synchronization IOCTL's on the hot path so a new kvm_s390_get_registers_partial() is introduced as a compliment to kvm_arch_get_registers(). The new function is called on the hot path, and kvm_arch_get_registers() is called when we need the complete runtime register state. kvm_arch_put_registers() is updated to only sync the partial runtime set when we've only dirtied the partial runtime set. This is to avoid sending bad data back to KVM if we've only partially synced the runtime register set. Signed-off-by: Jason J.

This patch adds a makefile, so we can build our ccw firmware. Also add the resulting binaries to .gitignore, so that nobody is annoyed they might be in the tree. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-04-26S390: ccw firmware: Add bootmap interpreterAlexander Graf1-0/+235
On s390, there is an architected boot map format that we can read to boot a certain entry off the disk. Implement a simple reader for this that always boots the first (default) entry. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-04-26S390: ccw firmware: Add glue headerAlexander Graf1-0/+131
Like all great programs, we have to call between different functions in different object files. And all of them need a common ground of defines. Provide a file that provides these defines. Signed-off-by: Alexander Graf <agraf@suse.de>

In order to communicate with the user, we need an I/O mechanism that he can read. Implement SCLP ASCII support, which happens to be the default in the s390 ccw machine. This file is missing read support for now. It can only print messages. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-04-26S390: ccw firmware: Add main programAlexander Graf1-0/+56
This C file is the main driving piece of the s390 ccw firmware. It provides a search for a workable block device, sets it as the default to boot off of and boots from it. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-04-26S390: IPL: Use different firmware for different machinesAlexander Graf4-6/+11
We have a virtio-s390 and a virtio-ccw machine in QEMU. Both use vastly different ways to do I/O. Having the same firmware blob for both doesn't really make any sense. Instead, let's parametrize the firmware file name, so that we can have different blobs for different machines. Signed-off-by: Alexander Graf <agraf@suse.de>
2013-04-26S390: IPL: Support ELF firmwareAlexander Graf1-6/+10
Our firmware blob is always a raw file that we load at a fixed address today. Support loading an ELF blob instead that we can map high up in memory. This way we don't have to be so conscious about size constraints. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-04-26sheepdog: fix loadvm operationLiu Yuan1-1/+53
Currently the 'loadvm' opertaion works as following: 1. switch to the snapshot 2. mark current working VDI as a snapshot 3. rely on sd_create_branch to create a new working VDI based on the snapshot This works not the same as other format as QCOW2. For e.g, qemu > savevm # get a live snapshot snap1 qemu > savevm # snap2 qemu > loadvm 1 # This will steally create snap3 of the working VDI Which will result in following snapshot chain: base <-- snap1 <-- snap2 <-- snap3 ^ | working VDI snap3 was unnecessarily created and might be annoying users. This patch discard the unnecessary 'snap3' creation. and implement rollback(loadvm) operation to the specified snapshot by 1. switch to the snapshot 2. delete working VDI 3. rely on sd_create_branch to create a new working VDI based on the snapshot The snapshot chain for above example will be: base <-- snap1 <-- snap2 ^ | working VDI Cc: qemu-devel@nongnu.org Cc: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Cc: Kevin Wolf <kwolf@redhat.com> Cc: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Liu Yuan <tailai.ly@taobao.com> Reviewed-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

When a snapshot is taken from out side of qemu (e.g. qemu-img snapshot), write requests to the current vdi return SD_RES_READONLY. In this case, the sheepdog block driver needs to update the current inode to the latest one and resend the write requests.

Target s390x uses ad-hoc macro magic to guess if the compiler supports the GCC extension __uint128_t. This patch uses the the dedicated macro CONFIG_INT128 defined by configure instead.
