* Add stubdomain support. See stubdom/README for usage details.Keir Fraser2008-02-1257-103/+2324
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in arch_limits.h so as to permit getting them from there without pulling all the internal Mini-OS defines. - Setup a xen-elf cross-compilation environment in stubdom/cross-root - Add a POSIX layer on top of Mini-OS by linking against the newlib C library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c - Cross-compile zlib and libpci too. - Add an xs.h-compatible layer on top of Mini-OS' xenbus. - Cross-compile libxc with an additional xc_minios.c and a few things disabled. - Cross-compile ioemu with an additional block-vbd, but without sound, tpm and other details. A few hacks are needed: - Align ide and scsi buffers at least on sector size to permit direct transmission to the block backend. While we are at it, just page-align it to possibly save a segment. Also, limit the scsi buffer size because of limitations of the block paravirtualization protocol. - Allocate big tables dynamically rather that letting them go to bss: when Mini-OS gets installed in memory, bss is not lazily allocated, and doing so during Mini-OS is unnecessarily trick while we can simply use malloc. - Had to change the Mini-OS compilation somehow, so as to export Mini-OS compilation flags to the Makefiles of libxc and ioemu.

* [Mini-OS] Fix domain blocking raceKeir Fraser2007-11-241-3/+20
| | | | | | | | | | A callback which wakes a thread may happen between the moment schedule() gives hand to the idle thread and the latter blocks the domain. Idle hence needs to atomically check that no thread is running and block, else awoken threads may have to wait up to 10 seconds. Signed-off-by: Samuel Thibault <samuel.thibault@citrix.com>
