* Fix emacs local variable block to use correct C style variable.David Vrabel2013-02-211-1/+1
| | | | | | | The emacs variable to set the C style from a local variable block is c-file-style, not c-set-style. Signed-off-by: David Vrabel <david.vrabel@citrix.com
* mini-os: use BSD sys/queue.h instead of Linux list.hIan Campbell2012-01-311-23/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latter is GPL which makes the whole of mini-os GPL rather than BSD as intended. In tree users are all GPL or GPL-compatible but we should fix this so that mini-os is BSD. Do so by using the same BSD sys/queue.h as we use in libxl. Tested with the builtin mini-os test app and qemu stubdomain, both of which appear to still function as expected. Move tools/libxl/external and the associated sed script to tools/include/xen-external to allow more sensible access from mini-os. Also add s/NULL/0/ in the sed script due to NULL not always being defined in stubdom code when mini-os/wait.h is included. As well as the obvious ABI changes there are a few API updates associated with the change: - struct rw_semaphore.wait_list is unused - remove_waiter needs to take the wait_queue_head The latter requires a qemu update, so there is also a QEMU_TAG update in this changeset. I sprinkled some extra-emacs local variables around the files I edited which didn't have them. I think this should be backported to the stable branches since external users of mini-os may have been mislead into thinking they could safely link mini-os against GPL-incompatible code.

* minios: do not expose #define current to applicationsKeir Fraser2008-10-271-5/+5
| | | | | | | | | | | | | | | | | Currently the minios headers do this: #define current get_current() Obviously when porting general code to this environment, this can cause problems ! The attached patch arranges for this only to be done if #define __MINIOS__ is declared, which is set up by the makefile in extras/mini-os. Suppressing the namespace pollution is necessary to get recent upstream qemu's to compile, since they (quite properly) use `current' as an ordinary identifier.

* prefix mini-os lists with minios_, drop QEMU_ prefix from QEMU_LIST_*Keir Fraser2008-08-081-9/+9

* stubdom: fixes to compile with qemu-xenKeir Fraser2008-07-101-3/+3
| | | | | | | | | | This adds fixes to the stub domain build into compiling Ian Jackson's qemu-xen. The most notable change is that mini-os headers now #include each other through a mini-os/ prefix, so that we can turn all -I into -isystem and still be sure that we include Mini-OS headers (and not qemu's console.h or blktaplib's list.h for instance...).

* stubdom: use host's gccKeir Fraser2008-07-041-22/+1
| | | | | | | | This makes stubdom use the host's gcc instead of downloading/compiling binutils+gcc. That requires a bunch of changes and even uncovered a few bugs, but saves a lot of time. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
