* libxc: introduce xc_domain_get_guest_width()Dario Faggioli2013-09-131-19/+1
| | | | | | | | | | | | | | As a wrapper to XEN_DOMCTL_get_address_size, and use it wherever the call was being issued directly via do_domctl(), saving quite some line of code. Actually, the function returns the guest width in bytes, rather than directly what XEN_DOMCTL_get_address_size provides (which is a number of bits), since that is what it is useful almost everywhere.

| | | | | | | | | | | | | | | | | 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>
* libxc: obtain correct length of p2m during core dumpingMarkus Gross2011-05-241-2/+1
| | | | | | | | | | | | | | | | | | | | | | while implementing core dumping functionality for the libxl driver of libvirt, I discovered an issue with mapping pages of a pv guest. After dumping the core of a pv guest the domain was not cleared up properly and some pages were not unmapped. This issue is similar to the one reported here: http://lists.xensource.com/archives/html/xen-devel/2011-05/msg01314.html In xc_domain_dumpcore_via_callback in the file xc_core.c the function xc_core_arch_map_p2m is called to map P2M_FL_ENTRIES pages to the variable p2m. But to unmap the pages later, the dinfo->p2m_size has to be set accordingly. This was not done, instead a variable named p2m_size was set. This way P2M_FL_ENTRIES was always zero and the pages were left mapped. [ This change should be considered for backport to relevant trees. ] Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com> Acked-by: Ian Jackson <ian.jackson@eu.citrix.com> Committed-by: Ian Jackson <ian.jackson@eu.citrix.com>

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-74/+79
| | | | | | | | | | | | | | | | | | | | 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>

* x86_64: allow more vCPU-s per guestKeir Fraser2009-06-181-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Since the shared info layout is fixed, guests are required to use VCPUOP_register_vcpu_info prior to booting any vCPU beyond the traditional limit of 32. MAX_VIRT_CPUS, being an implemetation detail of the hypervisor, is no longer being exposed in the public headers. The tools changes are clearly incomplete (and done only so things would build again), and the current state of the tools (using scalar variables all over the place to represent vCPU bitmaps) very likely doesn't permit booting DomU-s with more than the traditional number of vCPU-s. Testing of the extended functionality was done with Dom0 (96 vCPU-s, as well as 128 vCPU-s out of which the kernel elected - by way of a simple kernel side patch - to use only some, resulting in a sparse bitmap). ia64 changes only to make things build, and build-tested only (and the tools part only as far as the build would go without encountering unrelated problems in the blktap code).

* Domain core-dumping fixesKeir Fraser2009-03-121-0/+10
| | | | | | | | | | | | | | The code was attempting to use the domain's current number of pages (info.nr_pages) as a maximum index. We then walk the memory map and can easily over-write past the end of the nr_pages-sized array, if the domain has more pages mapped in than earlier (live dump). Restrict ourselves to the current number of pages. Also fix the dump core method in xend to actually implement the crash and live options. In particular this means that xend clients other than xm now get non-live dumps by default. Signed-off-by: John Levon <john.levon@sun.com>
* libxc: Support cross-bitness guest when core-dumpingKeir Fraser2009-01-151-13/+55
| | | | | | | | | | | This patch allows core-dumping to work on a cross-bit host/guest configuration, whereas previously that was not supported. It supports both PV and FV guests. The core file format generated by the host, needs to match that of the guest, so an alignment issue is addressed, along with the p2m frame list handling being done according to the guest size.

* [IA64] Don't share privregs with hvm domainAlex Williamson2007-10-221-1/+1
| | | | | | | | | | | | | | | | Don't share privregs with hvm domain and twist IA64 xen dump core format slightly. Xen shares privregs pages with IA64 HVM domain for xm dump-core to dump the pages. However sharing the page allows hvm guest domain peek/destroy the page contents that might cause xen crash. And the xen dump core file doesn't need privregs page because cpu context should be obtained from vcpu context in case of IA64 HVM domain. Although this patch modify xen dump core format, current crash utility (at least crash 4.0-4.7) doesn't look into .xen_ia64_mmapped_regs section and I don't know any other tools to understand xen dump core file. So this format modification doesn't cause incompatibility issue. Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp>
