* Domain core-dumping fixesKeir Fraser2009-03-122-1/+11
| | | | | | | | | | | | | | 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>

* hvm: passthrough MSI-X mask bit accelerationKeir Fraser2009-03-022-2/+5
| | | | | | | | | | Add a new parameter to DOMCTL_bind_pt_irq to allow Xen to know the guest physical address of MSI-X table. Also add a new MMIO intercept handler to intercept that gpa in order to handle MSI-X vector mask bit operation in the hypervisor. This reduces the load of device model considerably if the guest does mask and unmask frequently Signed-off-by: Qing He <qing.he@intel.com>

* bump libxenctrl and libxenguest versionsKeir Fraser2009-01-231-1/+1
| | | | | | | | | | | | | In c/s 19009 an incompatible change was made to the ABI of libelf-*, which are included in libxenctrl and libxenguest. To avoid client programs (such as python/lowlevel/xc/xc.so) picking up a wrong version and perhaps crashing, the soname should be changed. I have chosen the version number 3.4 as xen-unstable is currently the pre-3.4 branch. I assume we don't care about API/ABI stability within an unstable branch.

* libxc: Support cross-bitness guest when core-dumpingKeir Fraser2009-01-155-35/+135
| | | | | | | | | | | 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.

* Use -MMD -MF in tools/* rather than -Wp,-M...Keir Fraser2009-01-121-3/+0
| | | | | | | | | | | | | | | | | | | | | | If you use -MMD -MF then the correct .o filename is written to the .*.d file as the compiler driver arranges everything. This was done in 19010:275abe1c5d24 for the hypervisor. In this patch we do the same elsewhere in the xen-unstable tree, particularly tools/. Specifically: * Change tools/Rules.mk to add -MMD -MF ... to CFLAGS and set DEPS. * Remove -Wp,-MD... from every other Makefile * Remove setting of DEPS from every other Makefile * Ensure that every Makefile says -include $(DEPS) * Ensure that every Makefile's clean target removes $(DEPS) Some Makefiles were already halfway there, but often for a different variable name eg PROG_DEP. The variable name is now standardised in Rules.mk as DEPS. I have done a test build with this change, on Debian etch. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Implement libxc interface to PoD functionality: * Add xc_hvm_build_target_mem(), which takes both memsize and target. Memsize is the total memory, allocated in PoD pages and reported in the e820; target is the size of the cache. If these are the same, the normal funcitonality is called. (So you can use the same function to build always, and it will decide whether to use PoD or not.) * Add xc_domain_memory_[gs]et_pod_target(), which sets and/or returns information about the PoD cache and p2m entries.

|/ | | | | | | | | | | | ia64 linux 2.6.18 only use ar.itc for local ticks so that ar.itc didn't need paravirtualization and it can be work arounded when save/restore. However recent ia64 linux uses ar.itc for sched_clock() and CONFIG_VIRT_CPU_ACCOUNTING and other issues. So ar.itc needs paravirtualization.

* Use virtual 8086 mode for VMX guests with CR0.PE == 0Keir Fraser2008-12-092-5/+33
| | | | | | | | | | | | | When a VMX guest tries to enter real mode, put it in virtual 8086 mode instead, if that's possible. Handle all errors and corner cases by falling back to the real-mode emulator. This is similar to the old VMXASSIST system except it uses Xen's x86_emulate emulator instead of having a partial emulator in the guest firmware. It more than doubles the speed of real-mode operation on VMX. Signed-off-by: Tim Deegan <Tim.Deegan@citrix.com>
