* Transcendent memory ("tmem") for Xen.Keir Fraser2009-05-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tmem, when called from a tmem-capable (paravirtualized) guest, makes use of otherwise unutilized ("fallow") memory to create and manage pools of pages that can be accessed from the guest either as "ephemeral" pages or as "persistent" pages. In either case, the pages are not directly addressible by the guest, only copied to and fro via the tmem interface. Ephemeral pages are a nice place for a guest to put recently evicted clean pages that it might need again; these pages can be reclaimed synchronously by Xen for other guests or other uses. Persistent pages are a nice place for a guest to put "swap" pages to avoid sending them to disk. These pages retain data as long as the guest lives, but count against the guest memory allocation. Tmem pages may optionally be compressed and, in certain cases, can be shared between guests. Tmem also handles concurrency nicely and provides limited QoS settings to combat malicious DoS attempts. Save/restore and live migration support is not yet provided. Tmem is primarily targeted for an x86 64-bit hypervisor. On a 32-bit x86 hypervisor, it has limited functionality and testing due to limitations of the xen heap. Nearly all of tmem is architecture-independent; three routines remain to be ported to ia64 and it should work on that architecture too. It is also structured to be portable to non-Xen environments. Tmem defaults off (for now) and must be enabled with a "tmem" xen boot option (and does nothing unless a tmem-capable guest is running). The "tmem_compress" boot option enables compression which takes about 10x more CPU but approximately doubles the number of pages that can be stored. Tmem can be controlled via several "xm" commands and many interesting tmem statistics can be obtained. A README and internal specification will follow, but lots of useful prose about tmem, as well as Linux patches, can be found at http://oss.oracle.com/projects/tmem .

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.

* Have `make install' write the Python version number in the #!Keir Fraser2008-06-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | The Xen tools contain a number of Python extensions written in C. The C API to Python, used by these extensions, is not stable from one version of Python to the next. Our build system uses whatever version of Python is the default on the build system at that time to build these extensions. However, the actual scripts such as `xm' use #!/usr/bin/env python which uses whichever version of Python is the default on the deployment system at the time of invocation. If for any reason these two versions of Python are not the same (eg, because the system is built on one computer and executed on another, or because the system's gains a more recent Python installation alongside the original which changes the previous default), warnings and failures occur. In this patch I arrange for Python scripts to be installed via a special wrapper around `install', which determines the build-time Python version and path and then writes that into the #! line at the point of `make install' (or `make dist'). (It can also be overridden by setting PYTHON_PATH.) Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* tools: disable lomount and miniterm by defaultKeir Fraser2008-01-171-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lomount is a tool which reads and parses a partition table in a disk image block device and then uses mount -o ...offset=... to mount it. This is not an ideal approach. For example, if the intended filesystem has corrupted metadata the kernel's filesystem driver may start to write outside of the intended region. This might even be exploitable in some perverse circumstances. Nowadays people wanting to do this should use kpartx, which uses devmapper to create appropriate range mappings. So lomount should be disabled. miniterm may well be useful but it is a clone-and-hack of an upstream project and is currently built but not installed by default, partly because it doesn't make sense to install on the dom0 which it might be trying to debug. It is probably useful to retain these two programs in the source tree but IMO they should no longer be built by default. The attached patch does these things: * CONFIG_LOMOUNT and CONFIG_MINITERM in Config.mk can enable and disable these programs * They are disabled by default * If CONFIG_MINITERM=y it is still built but not installed. make -C tools/misc/miniterm install will install it.
