* Switch the default build to make the -xen kernel, not the -xen0 and -xenU3.0.2-rcemellor@leeni.uk.xensource.com2006-03-241-1/+1
| | | | | | | | | | | | kernels. Distros will be using -xen exclusively, so this change means that developers and users of unstable will be (by default) using the same configuration as the distros. This can be overridden by setting KERNELS="linux-2.6-xen0 linux-2.6-xenU" on the command line. Signed-off-by: Ewan Mellor <ewan@xensource.com>
* Fix bug 515 by adding a global lock around the hotplug scripts in the ↵harry@localhost.localdomain2006-03-241-0/+6
| | | | | | | | | | | | | | | non-udev hotplug case only. There are two possible root causes for 515, both of which are only problems in the non-udev hotplug case because udev uses udevsend which already implements the required serialisation. 1) Script concurrency. 2) Kernel reordering hotplug events. This changeset fixes (1) but not (2). Since (1) is the problem that seems to be happening this is probably OK. A fix for (2) for the hotplug case might be to add extra serialisation using state changes in the store but this would impact all the drivers and the code and extra complexity would be redundant once everyone had moved to udev. This doesn't seem worthwhile unless we actually start to see (2) happening.
* 1) Introduce new exception type XendInvalidDomain that maps to the high levelanthony@rhesis.austin.ibm.com2006-03-243-28/+12
| | | | | | | | | | | | | | | XEND_INVALID_DOMAIN faultType. 2) Fix exception logic in XMLRPCServer 3) Fix TCP server 4) Remove catching of ProtocolError in main.py. ProtocolErrors only occur when there is an exception in the exception handling code which shouldn't ever happen. I've reproduced the error cases described by Ewan with xend_domain_setTargetMemory and once I fixed the exception logic, I get a normal faultType of 1 as would be expected.

| * Reduce spin-waiting in Xen serial driver:kaf24@firebug.cl.cam.ac.uk2006-03-234-27/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Split the serial port lock into receiver and transmitter locks. 2. In the ns16550 interrupt, only call the generic serial service routines if there is receive (or transmit) work to do. 3. In the generic transmit ISR, avoid long spin-waits by *trying* to take the transmitter lock and, if that fails, check again whether the transmitter is empty. This will allow us to bail bail quickly if there is a long-term lock holder stuffing lots of bytes. Also, gdbstub should be setting its serial handle in synchronous mode, just for sanity.

* Support late binding of PCI devices to the PCI backend driver inkaf24@firebug.cl.cam.ac.uk2006-03-237-145/+525
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dom0. This allows you to bind devices to the backend driver *after* dom0 has booted. You are no longer required to specify the devices to hide on the kernel command-line. Using the bind/unbind driver attributes (see /sys/bus/pci/drivers/pciback), you can specify which devices that the PCI backend will seize. There are three new driver attributes in that directory: slots - lists all of the PCI slots that the PCI backend will try to seize new_slot - write the name of a slot here (in 0000:00:00.0 format) to have the PCI Backend seize the device in this slot remove_slot - write the name of a slot here to have the PCI Backend no longer try to seize a device in this slot Note that writing to new_slot/remove_slot does not actually change whether the PCI Backend is actually bound to the device in that slot or not. Instead, it tells the PCI backend which slots it should be interested in. The sysfs attributes "bind" and "unbind" (which are common to all drivers, not just the PCI Backend) must be used to actually add or remove a device from the PCI backend driver. Note that the syntax for specifying a device to bind and unbind is very strict (do not append a newline). For Example: # Add a new slot to the PCI Backend's list echo -n 0000:01:04.d > /sys/bus/pci/drivers/pciback/new_slot # Now that the backend is watching for the slot, bind to it echo -n 0000:01:04.d > /sys/bus/pci/drivers/pciback/bind # Unbind a PCI network card from its network driver echo -n 0000:05:02.0 > /sys/bus/pci/drivers/3c905/unbind # And now bind it to the PCI Backend echo -n 0000:05:02.0 > /sys/bus/pci/drivers/pciback/new_slot echo -n 0000:05:02.0 > /sys/bus/pci/drivers/pciback/bind Unfortunately, Linux makes it possible to remove (unbind) a PCI device from the PCI backend while that device is attached to a driver domain. It is also possible to unload the PCI Backend module while a PCI Frontend is attached. DON'T DO EITHER OF THESE ACTIONS. This patch will output warnings if you do try and do these. Be aware that while access to the configuration space of the device has been revoked, the driver domain can still access the I/O resources of the device as they have not been revoked (although I *hope* to explore adding support for this soon). Before unloading the module or unbinding a device, shutdown your driver domain. These patches also convert a few function and variable declarations to static (no sense in polluting the global namespace with local function names) and rename a few structures in drivers/xen/pciback/pci_stub.c.
