* passthrough: allow pt_bind_irq for msi updateKeir Fraser2009-04-151-5/+16
| | | | | | | | | | | | | Extend pt_bind_irq to handle the update of msi guest vector and flag. Unbind and rebind using separate hypercalls may not be viable sometime. For example, the guest may update MSI address/data on fly without disabling it first (e.g. change delivery/destination), implement these updates in such a way may result in interrupt loss.

* xend: serialise domain restart threadsKeir Fraser2009-04-151-1/+5
| | | | | | | | I observed from xend.log that several domain restart threads run simultaneously. This patch make it singleton. Without this, several coredump of a domain might be created. Signed-off-by: Kouya Shimura <kouya@jp.fujitsu.com>
* xend: fix avoidance to restart domain on crashKeir Fraser2009-04-151-15/+7
| | | | | | | | | | | | | | | | If a qemu-dm dies immediately (probably by wrong setting), xend repeats to restart a domain so many times.=20 That causes system overload. There is already a logic to avoid too early restarting, however, it might not work. Since xenstore entry 'xend/previous_restart_time' is volatile. XendDomainInfo.destroy() which removes the entry from xenstore is called in some places. Also, this patch prevents too early restarting even at the first domain creation.

* minios: fix a memory corruption in blkfrontKeir Fraser2009-04-141-5/+7
| | | | | | | | | The corruption happens every time we pass a sector aligned buffer (instead of a page aligned buffer) to blkfront_aio. To trigger the COW we have to write at least a byte to each page of the buffer, but we must be careful not to overwrite useful content.

* Fix cpufreq HW-ALL coordination handleKeir Fraser2009-04-145-59/+124
| | | | | | | | | | | | Currently cpufreq HW-ALL coordination is handled same way as SW-ALL. However, SW-ALL will bring more IPIs which is bad for cpuidle. This patch implement HW-ALL coordination handled in different way from SW-ALL, for the sake of performance and reduce IPIs. We also suspend/resume HW-ALL dbs timer for idle.

* tools: dom0 iptables rule ordering changeKeir Fraser2009-04-141-6/+9
| | | | | | | | | | | | | | | | | | | This patch makes two small changes to dom0 iptables rules that permit (and revoke) domU network access. First: Currently, a rule intended to allow domU network access is appended to the end of the FORWARD chain, where it can be preempted by other =20 rules. This patch causes the rule to be inserted at the top, where it's more likely to have the intended effect. Second: In some cases (e.g. Fedora 9's default iptables configuration), the first rule alone is insufficient to permit two-way packet flow. This patch adds a second rule to the FORWARD chain that permits replies to domU network requests to reach the domU vif. Signed-off-by: Chris Bookholt <hap10@tycho.ncsc.mil>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Do not share synchronization variables between the trap handler and the softirq handler, as this will cause problems. Abstract the synchronization bits into functions. Make the synchronization code aware of a panic, so that spinning with interrupts disabled is avoided. To avoid problems with MCEs happening while we're doing recovery actions in the softirq handler, implement a deferred list of telemetry structures, using the mctelem interfaces. Thist list will get updated atomically, so any additional MCEs will not cause error telemetry to be missed or not handled.

| * tools: Always use sane upstream (`native') python pathsKeir Fraser2009-04-0818-94/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, by default we would install our python modules into /usr/lib/python/xen, for example /usr/lib/python/xen/__init__.py. Upstream python's standard install location (a) includes the Python version number and (b) puts things in site-packages by default. Our best conjecture for the reason for this was an attempt to make the installs portable between different python versions. However, that doesn't work because compiled python modules (.pyc), and C python extensions corresponding to one version of python, are not compatible across different versions of python. This is why upstream include the version number. site-packages is the standard location for locally-installed packages and is automatically included on the python search path. In this change, we abandon our own unusual python path setup: * Invoke setup.py in an entirely standard manner. We pass PREFIX and DESTDIR using the appropriate options provided by setup.py for those purposes (adding them to setup.py calls which were previously lacking them). * Since the installation locations are now on the standard python path, we no longer need to add anything to the path in any of our python utilities. Therefore remove all that code from every python script. (Many of these scripts unconditionally added /usr/lib/python and /usr/lib64/python which is wrong even in the old world.) * There is no longer any special `Xen python path'. xen-python-path is no longer needed. It is no longer called by anything in our tree. However since out-of-tree callers may still invoke it, we retain it. It now prints a fixed string referring to a directory which does not to exist; callers (who use it to augment their python path) will thus add a nonexistent directory to their python path which is harmless. * Remove various workarounds including use of setup.py --home (which is intended for something completely different). * Remove tests for the XEN_PYTHON_NATIVE_INSTALL build-time environment variable. The new behaviour is the behaviour which we should have had if this variable had been set. That is, it is now as if this variable was always set but also bugs in the resulting install have been fixed. This should be a proper fix for the bug addressed by c/s 19515.
