* Include hw/hw.h exactly where neededMarkus Armbruster2019-08-161-1/+0Star
| | | | | | | | | | | | | | | | In my "build everything" tree, changing hw/hw.h triggers a recompile of some 2600 out of 6600 objects (not counting tests and objects that don't depend on qemu/osdep.h). The previous commits have left only the declaration of hw_error() in hw/hw.h. This permits dropping most of its inclusions. Touching it now recompiles less than 200 objects.

* xen: Import other xen/io/*.hAnthony PERARD2019-06-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | A Xen public header have been imported into QEMU (by f65eadb639 "xen: import ring.h from xen"), but there are other header that depends on ring.h which come from the system when building QEMU. This patch resolves the issue of having headers from the system importing a different copie of ring.h. This patch is prompt by the build issue described in the previous patch: 'Revert xen/io/ring.h of "Clean up a few header guard symbols"' ring.h and the new imported headers are moved to "include/hw/xen/interface" as those describe interfaces with a guest. The imported headers are cleaned up a bit while importing them: some part of the file that QEMU doesn't use are removed (description of how to make hypercall in grant_table.h have been removed). Other cleanup: - xen-mapcache.c and xen-legacy-backend.c don't need grant_table.h. - xenfb.c doesn't need event_channel.h.

* xen: re-name XenDevice to XenLegacyDevice...Paul Durrant2019-01-141-7/+7
| | | | | | | | | | | | | | | | | ...and xen_backend.h to xen-legacy-backend.h Rather than attempting to convert the existing backend infrastructure to be QOM compliant (which would be hard to do in an incremental fashion), subsequent patches will introduce a completely new framework for Xen PV backends. Hence it is necessary to re-name parts of existing code to avoid name clashes. The re-named 'legacy' infrastructure will be removed once all backends have been ported to the new framework. This patch is purely cosmetic. No functional change.

* qapi: Change Netdev into a flat unionEric Blake2016-07-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a mostly-mechanical conversion that creates a new flat union 'Netdev' QAPI type that covers all the branches of the former 'NetClientOptions' simple union, where the branches are now listed in a new 'NetClientDriver' enum rather than generated from the simple union. The existence of a flat union has no change to the command line syntax accepted for new code, and will make it possible for a future patch to switch the QMP command to parse a boxed union for no change to valid QMP; but it does have some ripple effect on the C code when dealing with the new types. While making the conversion, note that the 'NetLegacy' type remains unchanged: it applies only to legacy command line options, and will not be ported to QMP, so it should remain a wrapper around a simple union; to avoid confusion, the type named 'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions' in its place. Then, in the C code, we convert from NetLegacy to Netdev as soon as possible, so that the bulk of the net stack only has to deal with one QAPI type, not two. Note that since the old legacy code always rejected 'hubport', we can just omit that branch from the new 'NetLegacyOptions' simple union.

* xen: Switch to libxengnttab interface for compat shims.Ian Campbell2016-01-261-9/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | In Xen 4.7 we are refactoring parts libxenctrl into a number of separate libraries which will provide backward and forward API and ABI compatiblity. One such library will be libxengnttab which provides access to grant tables. In preparation for this switch the compatibility layer in xen_common.h (which support building with older versions of Xen) to use what will be the new library API. This means that the gnttab shim will disappear for versions of Xen which include libxengnttab. To simplify things for the <= 4.0.0 support we wrap the int fd in a malloc(sizeof int) such that the handle is always a pointer. This leads to less typedef headaches and the need for XC_HANDLER_INITIAL_VALUE etc for these interfaces. Note that this patch does not add any support for actually using libxengnttab, it just adjusts the existing shims.
