* [minios] Add xenbus shutdown control supportSamuel Thibault2012-11-302-0/+16
| | | | | | | | | | | | Add a thread watching the xenbus shutdown control path and notifies a wait queue. Add HYPERVISOR_shutdown convenient inline for minios shutdown.

| | | | | | | | | This patch disables the mfn_is_ram check in mini-os. The current check is insufficient and fails on some systems with larger than 4gb memory.

* minios: allow to allocate machine contiguous pagesKeir Fraser2009-03-131-0/+3
| | | | | | | | This is a port of XenLinux xen_alloc_contig_memory() to mini-os. A sufficiently privileged mini-os guest can exchange a small number of its pages with machine contiguous pages. Signed-off-by: Rolf Neugebauer <rolf.neugebauer@netronome.com>
* minios: add ioremap/iounmapKeir Fraser2009-03-021-0/+5

* mini-os: adding some missing posix function declarationsKeir Fraser2008-09-171-0/+1
| | | | | | | Adding some missing posix function declarations, to get rid of some qemu-remote compile time warnings. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

* stubdom: fixes to compile with qemu-xenKeir Fraser2008-07-105-7/+7
| | | | | | | | | | 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 Fraser2008-07-041-1/+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>
* 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.

* Add stubdomain support. See stubdom/README for usage details.Keir Fraser2008-02-125-15/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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 x86 arch_switch_threadKeir Fraser2007-11-231-37/+2
| | | | | | | | | Fix x86 arch_switch_thread by making it pure assembly. There were missing general register clobbers for x86_64, and BP should theorically be clobbered too, but gcc does not believe that, so the only simple safe solution is to use pure assembly.
