* contrib/: fix some comment spelling errorszhaolichang2020-09-171-1/+1
| | | | | | | | | | | I found that there are many spelling errors in the comments of qemu, so I used the spellcheck tool to check the spelling errors and finally found some spelling errors in the contrib folder.

* qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini2019-01-111-3/+1Star
| | | | | | | | | | | | Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

* ivshmem: use little-endian int64_t for the protocolMarc-André Lureau2015-10-263-19/+21
| | | | | | | | | | | | | The current ivshmem protocol uses 'long' for integers. But the sizeof(long) depends on the host and the endianess is not defined, which may cause portability troubles. Instead, switch to using little-endian int64_t. This breaks the protocol, except on x64 little-endian host where this change should be compatible.

* ivshmem: add check on protocol version in QEMUDavid Marchand2015-10-242-3/+11
| | | | | | | | | | | | | Send a protocol version as the first message from server, clients must close communication if they don't support this protocol version. Older QEMUs should be fine with this change in the protocol since they overrides their own vm_id on reception of an id associated to no eventfd.

* contrib: add ivshmem client and serverDavid Marchand2015-10-244-0/+885
When using ivshmem devices, notifications between guests can be sent as interrupts using a ivshmem-server (typical use described in documentation). The client is provided as a debug tool.
