* Fix emacs local variable block to use correct C style variable.David Vrabel2013-02-211-1/+1
| | | | | | | The emacs variable to set the C style from a local variable block is c-file-style, not c-set-style. Signed-off-by: David Vrabel <david.vrabel@citrix.com
* tools: drop ia64 supportIan Campbell2012-09-121-16/+4
| | | | | | | | | | | | | | | | | Removed support from libxc and mini-os. This also took me under xen/include/public via various symlinks. Dropped tools/debugger/xenitp entirely, it was described upon commit as: "Xenitp is a low-level debugger for ia64" and doesn't appear to be linked into the build anywhere. 99 files changed, 14 insertions(+), 32361 deletions(-) Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Keir Fraser <keir@xen.org> Committed-by: Ian Campbell <ian.campbell@citrix.com>
* mini-os: remove per-fd evtchn limitAlex Zeffertt2012-02-091-66/+74
| | | | | | | | | | | | | This changes the minios evtchn implementation to use a list instead of an array which ahis allows it to grow as necessary to support any number of ports, only limited by Xen (NR_EVS is 1024, should be enough for now).

* libxc: add xc_gnttab_map_grant_ref_notifyDaniel De Graaf2011-10-061-39/+15
| | | | | | | | | | | | | | | Normally, when a userspace process mapping a grant crashes, the domain providing the reference receives no indication that its peer has crashed, possibly leading to unexpected freezes or timeouts. This function provides a notification of the unmap by signalling an event channel and/or clearing a specific byte in the page. This also unifies the 3 very similar grant-mapping osdep interfaces into a single function instead of introducing yet another minor variation.

* libxc: convert gnttab interfaces to use an opaque handle typeIan Campbell2010-12-231-17/+17
| | | | | | | | | | | | | The xc_interface previously passed to xc_gnttab_* was only used for logging which can now be done via the xc_gnttab handle instead. This makes the interface consistent with the changes made to the main interface in 21483:779c0ef9682c. Also update QEMU_TAG to pull in the corresponding qemu change.

* minios: reverse layering of xc vs minios fd closeKeir Fraser2010-12-031-8/+24
| | | | | | | | | | | | Having minios close() call back into the libxc core close routines is backwards and unexpected. On every other OS the libxc core close routine calls close(). Export minios specific functions from the minios libxc code to implement fd closing for each type of xc file handle and simply call close() in the core close routine.

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-18/+18
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* minios: Fix lost eventsKeir Fraser2008-03-181-11/+3
| | | | | | | | | | | | | | | evtchn_bind_interdomain used to clear any already pending event before binding a handler, because else the handler may be called before it is ready. That however leads to missed events, which I had to workaround for the HVM case. This changes the semantics of bind_evtchn, and thus of all the event channel binding functions (bind_virq, evtchn_alloc_unbound, evtchn_bind_interdomain) into not unmasking the event itself, hence letting the caller initialize properly before unmasking the port (e.g. record the port number in an appropriate place).

- 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.
