2012-12-06Create qemu-types.h for struct typedefsEduardo Habkost1-51/+1
Instead of keeping all those struct typedefs in qemu-common.h, move it to a header that can be safely included by other headers, containing only the struct typedefs and not pulling in other dependencies. Also, move some of the qdev-core.h typedefs to the new file, too, so other headers don't need to include qdev-core.h only because of DeviceState and other typedefs. This will help us remove qemu-common.h dependencies from some headers later. Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>

2012-11-15qemu-common.h: Comment about usage rulesEduardo Habkost1-1/+10
Every time we make a tiny change on a header file, we often find circular header dependency problems. To avoid this nightmare, we need to stop including qemu-common.h from other headers, and we should gradually move the declarations from the catch-all qemu-common.h header to their specific headers. This simply adds a comment documenting the rules about qemu-common.h, hoping that people will see it before including qemu-common.h from other header files, and before adding more declarations to qemu-common.h.

setsockopt needs a type cast for MinGW. That type cast is missing in a recent commit which results in a compiler warning.

2012-08-09iscsi: Pick default initiator-name based on the name of the VMRonnie Sahlberg1-0/+1
This patch updates the iscsi layer to automatically pick a 'unique' initiator-name based on the name of the vm in case the user has not set an explicit iqn-name to use. Create a new function qemu_get_vm_name() that returns the name of the VM, if specified. This way we can thus create default names to use as the initiator name based on the guest session. If the VM is not named via the '-name' command line argument, the iscsi initiator-name used wiull simply be iqn.2008-11.org.linux-kvm If a name for the VM was specified with the '-name' option, iscsi will use a default initiatorname of iqn.2008-11.org.linux-kvm:<name> These names are just the default iscsi initiator name that qemu will generate/use only when the user has not set an explicit initiator name via the commandlines or config files.

2012-08-02Support 'help' as a synonym for '?' in command line optionsPeter Maydell1-0/+18
For command line options which permit '?' meaning 'please list the permitted values', add support for 'help' as a synonym, by abstracting the check out into a helper function. This change means that in some cases where we were being lazy in our string parsing, "?junk" will now be rejected as an invalid option rather than being (undocumentedly) treated the same way as "?". Update the documentation to use 'help' rather than '?', since '?' is a shell metacharacter and thus prone to fail confusingly if there is a single character filename in the current working directory and the '?' has not been escaped. It's therefore better to steer users towards 'help', though '?' is retained for backwards compatibility. We do not, however, update the output of the system emulator's -help (or any documentation autogenerated from the qemu-options.hx which is the source of the -help text) because libvirt parses our -help output and will break. At a later date when QEMU provides a better interface so libvirt can avoid having to do this, we can update the -help text too.

2012-06-11cleanup qemu_co_sendv(), qemu_co_recvv() and friendsMichael Tokarev1-20/+17
The same as for non-coroutine versions in previous patches: rename arguments to be more obvious, change type of arguments from int to size_t where appropriate, and use common code for send and receive paths (with one extra argument) since these are exactly the same. Use common iov_send_recv() directly. qemu_co_sendv(), qemu_co_recvv(), and qemu_co_recv() are now trivial #define's merely adding one extra arg. qemu_co_sendv() and qemu_co_recvv() callers are converted to different argument order and extra `iov_cnt' argument. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2012-06-11rename qemu_sendv to iov_send, change proto and move declarations to iov.hMichael Tokarev1-3/+0
Rename arguments and use size_t for sizes instead of int, from int qemu_sendv(int sockfd, struct iovec *iov, int len, int iov_offset) to ssize_t iov_send(int sockfd, struct iovec *iov, size_t offset, size_t bytes) The main motivation was to make it clear that length and offset are in _bytes_, not in iov elements: it was very confusing before, because all standard functions which deals with iovecs expects number of iovs, not bytes, even the fact that struct iovec has iov_len and iov_ prefix does not help. With "bytes" and "offset", especially since they're now size_t, it is much more explicit. Also change the return type to be ssize_t instead of int. This also changes it to match other iov-related functons, but not _quite_: there's still no argument indicating where iovec ends, ie, no iov_cnt parameter as used in iov_size() and friends. If will be added in subsequent patch/rewrite. All callers of qemu_sendv() and qemu_recvv() and related, like qemu_co_sendv() and qemu_co_recvv(), were checked to verify that it is safe to use unsigned datatype instead of int. Note that the order of arguments is changed to: offset and bytes (len and iov_offset) are swapped with each other. This is to make them consistent with very similar functions from qemu_iovec family, where offset always follows qiov, to mean the place in it to start from.

2012-06-11change qemu_iovec_to_buf() to match other to,from_buf functionsMichael Tokarev1-1/+2

2012-06-11consolidate qemu_iovec_copy() and qemu_iovec_concat() and make them consistentMichael Tokarev1-3/+2
qemu_iovec_concat() is currently a wrapper for qemu_iovec_copy(), use the former (with extra "0" arg) in a few places where it is used. Change skip argument of qemu_iovec_copy() from uint64_t to size_t, since size of qiov itself is size_t, so there's no way to skip larger sizes. Rename it to soffset, to make it clear that the offset is applied to src. Also change the only usage of uint64_t in hw/9pfs/virtio-9p.c, in v9fs_init_qiov_from_pdu() - all callers of it actually uses size_t too, not uint64_t. One added restriction: as for all other iovec-related functions, soffset must point inside src. Order of argumens is already good: qemu_iovec_memset(QEMUIOVector *qiov, size_t offset, int c, size_t bytes) vs: qemu_iovec_concat(QEMUIOVector *dst, QEMUIOVector *src, size_t soffset, size_t sbytes) (note soffset is after _src_ not dst, since it applies to src; for memset it applies to qiov). Note that in many places where this function is used, the previous call is qemu_iovec_reset(), which means many callers actually want copy (replacing dst content), not concat. So we may want to add a wrapper like qemu_iovec_copy() with the same arguments but which calls qemu_iovec_reset() before _concat(). Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
2012-06-11allow qemu_iovec_from_buffer() to specify offset from which to start copyingMichael Tokarev1-1/+2
Similar to qemu_iovec_memset(QEMUIOVector *qiov, size_t offset, int c, size_t bytes); the new prototype is: qemu_iovec_from_buf(QEMUIOVector *qiov, size_t offset, const void *buf, size_t bytes); The processing starts at offset bytes within qiov. This way, we may copy a bounce buffer directly to a middle of qiov. This is exactly the same function as iov_from_buf() from iov.c, so use the existing implementation and rename it to qemu_iovec_from_buf() to be shorter and to match the utility function. As with utility implementation, we now assert that the offset is inside actual iovec. Nothing changed for current callers, because `offset' parameter is new. While at it, stop using "bounce-qiov" in block/qcow2.c and copy decrypted data directly from cluster_data instead of recreating a temp qiov for doing that.

2012-06-11consolidate qemu_iovec_memset{,_skip}() into single function and use ↵Michael Tokarev1-3/+2
existing iov_memset() This patch combines two functions into one, and replaces the implementation with already existing iov_memset() from iov.c. The new prototype of qemu_iovec_memset(): size_t qemu_iovec_memset(qiov, size_t offset, int fillc, size_t bytes) It is different from former qemu_iovec_memset_skip(), and I want to make other functions to be consistent with it too: first how much to skip, second what, and 3rd how many of it. It also returns actual number of bytes filled in, which may be less than the requested `bytes' if qiov is smaller than offset+bytes, in the same way iov_memset() does. While at it, use utility function iov_memset() from iov.h in posix-aio-compat.c, where qiov was used. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>

This adds support for SHPC interface, as defined by PCI Standard Hot-Plug Controller and Subsystem Specification, Rev 1.0 http://www.pcisig.com/specifications/conventional/pci_hot_plug/SHPC_10 Only SHPC intergrated with a PCI-to-PCI bridge is supported, SHPC integrated with a host bridge would need more work. All main SHPC features are supported: - MRL sensor - Attention button - Attention indicator - Power indicator Wake on hotplug and serr generation are stubbed out but unused as we don't have interfaces to generate these events ATM. One issue that isn't completely resolved is that qemu currently expects an "eject" interface, which SHPC does not provide: it merely removes the power to device and it's up to the user to remove the device from slot.

The qemu-img.c:is_not_zero() function checks if a buffer contains all zeroes. This function will come in handy for zero-detection in the block layer, so clean it up and move it to cutils.c. Note that the function now returns true if the buffer is all zeroes. This avoids the double-negatives (i.e. !is_not_zero()) that the old function can cause in callers.
