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: NAlexander Graf <agraf@suse.de>

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: NAlexander 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: NAlexander Graf <agraf@suse.de>

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: NAlexander Graf <agraf@suse.de>

We want to write most of our code in C, so add a small assembly stub that jumps straight into C code for us to continue booting. Signed-off-by: NAlexander Graf <agraf@suse.de>

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: NAlexander Graf <agraf@suse.de>

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: NAlexander Graf <agraf@suse.de>

We can have different load addresses for different blobs we boot with. Make the reset IP dynamic, so that we can handle things more flexibly. Signed-off-by: NAlexander Graf <agraf@suse.de>

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: NLiu Yuan <tailai.ly@taobao.com> Reviewed-by: NMORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: NStefan 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.

Commit a9ccedc3 frees the QemuOpts for the driver-specific options immediately, even though it still needs the filename string that is contained there. This doesn't work.

We don't want to commit to the API yet before everything is worked out. Disable it for the 1.5 release. This commit is meant to be reverted after the 1.5 release.

The 'TRIM' command from VM that is to release underlying data storage for better thin-provision is already supported by the Sheepdog. This patch adds the TRIM support at QEMU part. For older Sheepdog that doesn't support it, we return 0(success) to upper layer.

libssh2 >= 1.2.8 is required to enable this block device (because that version introduced the libssh2_session_handshake call). Change the test to use pkg-config exclusively. If the user requests --enable-libssh2 and the minimum version is not available, then the following error is displayed: $ ./configure --enable-libssh2 ERROR: libssh2 >= 1.2.8 required for --enable-libssh2 If --enable-libssh2 is not specified, then the feature is silently disabled if sufficiently new libssh2 is not available.

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. This fixes compilation with the CIL source code analyzer, which uses GCC as a preprocessor but does not support __uint128_t.

While reviewing some patches I found this problem where tcp_chr_accept does not clear listen_tag when returning FALSE, leading to a double g_source_remove of the underlying source. Not really a problem unless the id gets re-used in between, but still something we should fix. While at it I've also reviewed all the other code in qemu-char.c for similar problems and found that pty_chr_timer has the same problem.
