* minios: Disable -DGNT_DEBUG and -DGNTMAP_DEBUGMatthew Fioravante2012-11-131-2/+2
| | | | | | | | | Disabling the above flags in default mini-os build. They generate a lot of spam. Signed-off-by: Matthew Fioravante <matthew.fioravante@jhuapl.edu> Acked-by: Samuel Thibault <samuel.thibault@ens-lyon.org> Committed-by: Ian Campbell <ian.campbell@citrix.com>
* mini-os: create app-specific configurationDaniel De Graaf2012-02-091-2/+2
| | | | | | | | | | | | | | Instead of using CONFIG_QEMU and CONFIG_GRUB to enable or disable minios code, create CONFIG_ items for features and use application-specific configuration files to enable or disable the features. The configuration flags are currently added to the compiler command line; as the number of flags grows this may need to move to a header.

* minios: grant table map (gntdev) for miniosKeir Fraser2008-07-241-0/+1
| | | | | | | | 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>
* stubdom: use host's gccKeir Fraser2008-07-041-3/+4
| | | | | | | | 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,stubdom: Add OBJ_DIR parameter to compile outside sources,Keir Fraser2008-06-171-3/+3
| | | | | | | which permits to easily compile mini-os in various flavors. Also clean some parts of stubdom build. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* minios: blkfront_aio_poll may reenterKeir Fraser2008-03-261-4/+4
| | | | | | | | | | if the callback calls blkfront_sync for instance. In such a case, we would see responses and hence release grants several times. We need to be more synchronous and stop when we detect that we have re-entered. This fixes HVM restore with stubdomains. Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* minios: more assertionsKeir Fraser2008-03-261-0/+4
| | | | | | | | - assert that we never allocate or free the same grant twice - assert that network packets do not exceed a page - assert that incoming network event IDs make sense Signed-off-by: Samuel Thibault <samuel.thibault@eu.citrix.com>
* Add stubdomain support. See stubdom/README for usage details.Keir Fraser2008-02-121-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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.
