* stubdom: add stub functions to reduce qemu patchesKeir Fraser2008-07-091-0/+11
| | | | Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* stubdom: use host's gccKeir Fraser2008-07-043-2/+5
| | | | | | | | 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>

* minios: Fix width of shifted 1Keir Fraser2008-05-241-1/+1
| | | | | | Shifting 1 more that 32 bits requires 1 to be long-typed. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* pvfb/ioemu: transmit refresh interval advice from backend to frontendKeir Fraser2008-05-121-0/+20
| | | | | | which permits the frontend to avoid useless polls. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* stubdom: sparse application's BSS by linking it separately first, putKeir Fraser2008-04-161-0/+35
| | | | | | | markers at its beginning and end, and then link with mini-os. That permits to stick a bit more to upstream qemu. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* minios: Fix xfree() bug.Keir Fraser2008-04-021-7/+7
| | | | | | | | It has to check first if the memory to free is so big as to be freed directly by free_pages. mini-os domains crash without this patch if vfb is misconfigured. Signed-off-by: INAKOSHI Hiroya <inakoshi.hiroya@jp.fujitsu.com>

| | | | | Needed on ia64, speeds up on x86. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* Add stubdomain support. See stubdom/README for usage details.Keir Fraser2008-02-122-0/+1270
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | introduced to simplify the porting. 64 bit version of Mini-os now compiles, but does not work because of the pagetables and some bits of scheduler not being written. Signed-off-by: Grzegorz Milos <gm281@cam.ac.uk>
