* stubdom: turn off_t 64bit on x86Keir Fraser2008-08-083-3/+11
| | | | | | | | We can decide to make off_t 64bit instead of implementing the LFS tricks. Name corresponding functions foo64 to permit simple caml programs linking. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* minios: grant table map (gntdev) for miniosKeir Fraser2008-07-242-0/+38
| | | | | | | | I've implemented a grant map for mini-os to support the xc_gnttab_*() functions, the equivalent of gntdev in linux. This is useful for my work in putting xenstored in a stub domain. Signed-off-by: Diego Ongaro <diego.ongaro@citrix.com>
* mini-os: export allocate_ondemandKeir Fraser2008-07-181-0/+1
| | | | | | | allocate_ondemand can be used to allocate addresse space. Primarily used for mapping MFNs, it can also be used e.g. to map grant refs. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>

* stubdom: fixes to compile with qemu-xenKeir Fraser2008-07-1036-59/+62
| | | | | | | | | | 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 Fraser2008-07-049-26/+100
| | | | | | | | 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>

| * Add PV-GRUBKeir Fraser2008-06-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | This fetches GRUB1 sources, applies the {graphical, print function, save default, and ext3_256byte} patches from debian, and applies a patch to make it work on x86_64 and port it to Mini-OS. By using libxc, PV-GRUB can then "kexec" the loaded kernel from inside the domain itself, hence permitting to avoid the security-concerned pygrub.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.
