2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini1-4/+1
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>
2018-02-09Move include qemu/option.h from qemu-common.h to actual usersMarkus Armbruster1-1/+1
qemu-common.h includes qemu/option.h, but most places that include the former don't actually need the latter. Drop the include, and add it to the places that actually need it. While there, drop superfluous includes of both headers, and separate #include from file comment with a blank line. This cleanup makes the number of objects depending on qemu/option.h drop from 4545 (out of 4743) to 284 in my "build everything" tree.

2016-03-22include/qemu/osdep.h: Don't include qapi/error.hMarkus Armbruster1-0/+1
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little. More work is needed for that one. Signed-off-by: Markus Armbruster <armbru@redhat.com> [Fix compilation without the spice devel packages. - Paolo] Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2016-01-13error: Use error_report_err() instead of ad hoc printsMarkus Armbruster1-3/+1
Unlike ad hoc prints, error_report_err() uses the error whole instead of just its message obtained with error_get_pretty(). This avoids suppressing its hint (see commit 50b7b00). Example: $ bld/ivshmem-server -l 42@ Parameter 'shm_size' expects a size You may use k, M, G or T suffixes for kilobytes, megabytes, gigabytes and terabytes. The last line is new with this patch. While there, drop a "cannot parse shm size: " message prefix; it's redundant, because the error message proper is always of the form "Parameter 'shm_size' expects ...".

2015-10-26ivshmem: use little-endian int64_t for the protocolMarc-André Lureau2-7/+8
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.
