* xen/compat: support XEN_HAVE_FOO ifdefs in public interfaceIan Campbell2013-08-202-0/+6
| | | | | | | | | | | | | | | | This allows us expose or hide interface features on different architectures without requiring nasty arch-specific ifdeffery. Preserves any #ifdef with a XEN_HAVE_* symbol name, as well as any #else or The ifdef symbol becomes COMPAT_HAVE in the compat versions so that architectures can enable or disable interfaces for compat mode too. (This actually just fell out of the way the existing stuff works and it didn't seem worth jumping through hoops to make the name remain XEN_HAVE).

* scmversion: 'Improve' svn interaction.Andrew Cooper2013-08-021-10/+1
| | | | | | | | | | | Xen has never been in an svn tree, and the current code will unconditionally create a .svn directory when run from a tarball. Therefore, simply discard the svn support.

* Use {git, hg, svn} commit id if available for xen_changesetMarek Marczykowski2013-05-131-0/+101
| | | | | | | | | As Xen uses git as primary repository, get git commit id for xen_changeset info. Signed-off-by: Marek Marczykowski <marmarek@invisiblethingslab.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Keir Fraser <keir@xen.org>
* Do not re-define XEN_ROOT in hypervisor sub-Makefiles.Keir Fraser2011-03-172-2/+0
| | | | | | | We can globally export it from xen/Makefile instead, as all hypervisor builds have this Makefile at their root. Signed-off-by: Keir Fraser <keir@xen.org>
* x86-64: reduce symbol table sizeKeir Fraser2009-07-131-31/+12
| | | | | | | | | | | | | | With all of Xen's symbols sitting within a 2Gb range on x86-64, they can be referred to by the kallsyms-like offset table using 4- instead of 8-byte slots. The marker table can use 4-byte slots in all cases, just like the table entry counts can (though that's only a minor improvement). If ia64's PERCPU_ADDR got moved down to (KERNEL_START + 2Gb - PERCPU_PAGE_SIZE), it could also utilize the more compact form. Signed-off-by: Jan Beulich <jbeulich@novell.com>

* tmem: fix 32-on-64 supportKeir Fraser2009-06-171-2/+58
| | | | | | | | | This implicitly required coverting the tmem_op structure from anonymous to standard struct/union sub-fields, and extending the get-fields.sh helper script to deal with typedef-ed guest handles used as types of translated compound type fields.

* x86 mce: fix c/s 17968 for 32-on-64Keir Fraser2009-03-311-1/+1
| | | | | | | | | | | | | | | | 32-on-64 aspects were not properly considered. Add respective checking, and adjust structure layouts for the cases where the checking pointed out issues. Also, - fix a potential memory corruption issue (do_mca() could write beyond log_cpus' end if the guest specified less than the number of online CPUs - there is no reason to make the (not even properly prefixed) definitions in xen/public/arch-x86/xen-mca.h globally visible by including the file from xen/public/arch-x86/xen.h.

* x86: fix a few 32-on-64 compat mode issuesKeir Fraser2008-05-121-1/+0
| | | | | | | | | | | - handle VCPUOP_register_vcpu_info and VCPUOP_get_physid (and add respective layout checks) - add missing structure size check for struct vcpu_info - add missing layout check for vcpu_set_periodic_timer - handle VCPUOP_set_singleshot_timer via argument translation as the structure sizes differ (due to padding in 64-bits) Signed-off-by: Jan Beulich <jbeulich@novell.com>

Rename xen-2.4.16 to just "xen" to reflect that it hasn't got any relation to the Linux kernel version.
