* OvmfPkg/XenBusDxe: Add Event Channel into XenBus protocol.Anthony PERARD2014-10-293-0/+110
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds three event channel related functions: - EventChannelAllocate: Allocate an event channel port that can be bind from a specified domain. - EventChannelNotify: Send an event to the remote end of a channel. - EventChannelClose: Close a local event channel port. Change in V3: - eventchannel, update protocol to return error code. - expand patch description - Add comments in the XenBus Protocol header. Change in V2: - coding style - adding comment to functions - Rename Xenbus to XenBus.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a bus-like on top of XenStore. It will look for advertised ParaVirtualized devices and initialize them by producing XenBus protocol. Change in V4: - Replace the license by the commonly used file header text. - Clean XenBus.h header (remove copyright that does not belong to the file anymore; and rewrite the brief description of the file) - Fix description on the function Change in V3: - Insert to ChildList later, once populated. - Remove XENBUS_XENSTORE_NODE macro. - add comment to XenBusAddDevice and XenBusEnumerateBus about concurrency calls. - Add a description to the introduced member to the protocol. Change in V2: - comment, file header - Fix comment style - Error handling in the main init function - coding style - Fix error path in add device.

* OvmfPkg/XenBusDxe: Add XenStore client implementationAnthony PERARD2014-10-294-0/+1685
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | XenStore is a key/value database, which is running on another virtual machine. It can be accessed through shared memory. This is a client implementation. Change in V3: - moving xs_wire.h from patch #1 to this patch - fix return value of XenStoreListDirectory - Use a timeout to print a debug message if the other side of the xenstore ring does not notify through the event channel. This is done with the new XenStoreWaitForEvent function. - Have XenStoreReadReply check status of XenStoreProcessMessage and return an error if needed. - Have XenStoreTalkv return the status of XenStoreReadReply. - Have a loop to check for the quiescent of the response ring in the XenStoreInitComms function. (with a timeout of 5 seconds) - use the recently introduced XenStore 'closing' feature. Change in V2: - Change comment style, from freebsd to ovmf - Fix type of EventChannel - Fix debug print, no more cast - Implement XenStoreDeinit. - Clean up comments - Fix few codding style issue - Add FAIL xenstore status value.
