similar to: [PATCH] [Mini-OS] add xenbus token support and separate watch event queues

This patch cleans up some 80-odd warnings I was seeing when compiling the xenpci driver, all completely trivial. It also replaces the use of asm for calling cpuid with the __cpuid compiler intrinsic, and modifies calling code accordingly. I''m pretty sure my mailer going to mangle the inline patch (below) so I''m attaching the pristine version. (will try to fix for next time) --

Recent xen uses xenbus to suspend PV-on-HVM guest domain. The related code in the xen-unstable tree will fall into infinite loop when guest domain failed on suspending one or more devices. The patch attached changes the logic, and raises an XendError after 1 minute waiting. The patch also makes use of "control/shutdown" entry in xenstore, allows guest kernel report the failure of the

This patch series contains a set of patches making minios rather easier to use, from an application development point of view. Overview of patches: 1 Command line argument parsing support, from Xen. 2 Weak console handler function. 3 Build system tweaks for application directories. 4 Trailing whitespace cleanup. (because it is very messy) Patch 4 is likely to be more controversial than

Hi Keir: [LINUX] netfront: Cleanup and fix TSO/GSO/CHECKSUM conditionals This patch tries to minimise the amount of code that is conditionally compiled. This is desirable (and the Linux way) as it helps to prevent people breaking code unwittingly since conditionals may hide compile problems. It also adds a missing conditional around the TSO ethtool operations. This also helps the building of

Add a thread watching the xenbus shutdown control path and notifies a wait queue. Add HYPERVISOR_shutdown convenient inline for minios shutdown. Add proper shutdown to the minios test application.

This patch adds a new feature called feature-split-event-channels for netfront, enabling it to handle TX and RX events separately. If netback does not support this feature, it falls back to use single event channel.

Unfortunately we managed to not catch in our automatic testing this oversight during the porting of the corresponding pv-ops patch (info->irq now getting set later, which doesn''t matter for pv-ops as that has the event channel at hand).

Frontends are expected to write their protocol ABI to xenstore. Since the protocol ABI defaults to the backend's native ABI, things work fine without that as long as the frontend's native ABI is identical to the backend's native ABI. This is not the case for xen-blkfront running 32-on-64, because its ABI differs between 32 and 64 bit, and thus needs this fix. Based on

Hello, This patch allows userspace tools on a domU to setup a watch on the xenstore. It does this by intercepting XS_WATCH requests written to /proc/xen/xenbus and then re-submitting the request to the in-kernel xenstore interface, in linux-2.6-xen-sparse/drivers/xen/xenbus/xenbus_xs.c. When a callback occurs, an in-kernel function is invoked, which then reconstructs a response in the format

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths

Netback and netfront only use one event channel to do tx / rx notification. This may cause unnecessary wake-up of process routines. This patch adds a new feature called feautre-split-event-channel to netback, enabling it to handle Tx and Rx event separately. Netback will use tx_irq to notify guest for tx completion, rx_irq for rx notification. If frontend doesn''t support this feature,
