Now that 4.2 and earlier are no longer supported "xc_interface *" is always the right type for the xc interface handle. With this we can also simplify the handling of the xenforeignmemory compatibility wrapper by making xenforeignmemory_handle == xc_interface, instead of an xc_interface* and remove various uses of & and *h.

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 libxenforeignmemory which provides access to privileged foreign mappings and which will provide an interface equivalent to xc_map_foreign_{pages,bulk}. The new xenforeignmemory_map() function behaves like xc_map_foreign_pages() when the err argument is NULL and like xc_map_foreign_bulk() when err is non-NULL, which maps into the shim here onto checking err == NULL and calling the appropriate old function. Note that xenforeignmemory_map() takes the number of pages before the arrays themselves, in order to support potentially future use of variable-length-arrays in the prototype (in the future, when Xen's baseline toolchain requirements are new enough to ensure VLAs are supported). In preparation for adding support for libxenforeignmemory add support to the <=4.0 and <=4.6 compat code in xen_common.h to allow us to switch to using the new API. These shims will disappear for versions of Xen which include libxenforeignmemory. Since libxenforeignmemory will have its own handle type but for <= 4.6 the functionality is provided by using a libxenctrl handle we introduce a new global xen_fmem alongside the existing xen_xc. In fact we make xen_fmem a pointer to the existing xen_xc, which then works correctly with both <=4.0 (xc handle is an int) and <=4.6 (xc handle is a pointer). In the latter case xen_fmem is actually a double indirect pointer, but it all falls out in the wash. Unlike libxenctrl libxenforeignmemory has an explicit unmap function, rather than just specifying that munmap should be used, so the unmap paths are updated to use xenforeignmemory_unmap, which is a shim for munmap on these versions of xen. The mappings in xen-hvm.c do not appear to be unmapped (which makes sense for a qemu-dm process) In fb_disconnect this results in a change from simply mmap over the existing mapping (with an implicit munmap) to expliclty unmapping with xenforeignmemory_unmap and then mapping the required anonymous memory in the same hole. I don't think this is a problem since any other thread which was racily touching this region would already be running the risk of hitting the mapping halfway through the call. If this is thought to be a problem then we could consider adding an extra API to the libxenforeignmemory interface to replace a foreign mapping with anonymous shared memory, but I'd prefer not to.

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.

Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

The current implementation of xen_backend only provides 32 bit integer functions to write to xenstore. This patch adds two functions that allow writing 64 bit integers (one generic function and another for the backend only). This patch also fixes the size of the char arrays used to represent these integers as strings (originally 32 bytes, however no more than 12 bytes are needed for 32 bit integers and no more than 21 bytes are needed for 64 bit integers).

Done with this script: cd hw for i in `find . -name '*.h' | sed 's/^..//'`; do echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,' done | sed -i -f - `find . -type f` This is so that paths remain valid as files are moved. Instead, files in hw/dataplane are referenced with the relative path. We know they are not going to move to include/, and they are the only include files that are in subdirectories _and_ move.

Since version 4.4.x, gcc supports additional format attributes. __attribute__ ((format (gnu_printf, 1, 2))) should be used instead of __attribute__ ((format (printf, 1, 2)) because QEMU always uses standard format strings (even with mingw32). The patch replaces format attribute printf / __printf__ by macro GCC_FMT_ATTR which uses gnu_printf if supported. It also removes an #ifdef __GNUC__ (not needed any longer).

Problem: Our file sys-queue.h is a copy of the BSD file, but there are some additions and it's not entirely compatible. Because of that, there have been conflicts with system headers on BSD systems. Some hacks have been introduced in the commits 15cc9235, f40d7537, 96555a96 and 3990d09a but the fixes were fragile. Solution: Avoid the conflict entirely by renaming the functions and the file.

This patch adds a network interface backend driver to qemu. It is a pure userspace implemention using the gntdev interface. It uses "qnet" as backend name in xenstore so it doesn't interfere with the netback backend (aka "vnif"). The network backend is hooked into the corrosponding qemu vlan, i.e. vif 0 is hooked into vlan 0. To make the packages actually arrive somewhere you additionally have to link the vlan to the outside world using the usual qemu command line options such as "-net tap,...".
