* OvmfPkg: replace strict XenHypercallLib construction with explicit queryLaszlo Ersek2015-03-031-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | XenHypercallLib has two clients at the moment: XenBusDxe and XenConsoleSerialPortLib. Currently, when XenBusDxe starts on a non-Xen X86 platform (ie. as part of OVMF not running on Xen), the X86XenHypercallLib instance built into it fails to initialize, which triggers an ASSERT() in auto-generated code. Instead, let's call XenHypercallIsAvailable() in the driver's entry point, and exit cleanly when the driver is started on a non-Xen platform. Modify the constructor of XenConsoleSerialPortLib similarly; we shouldn't proceed if Xen is not available. In practice this check should never fail, because XenConsoleSerialPortLib is only used on ARM, and ArmXenHypercallLib is always available; but nonetheless we should be pedantic.

This involves: - removing the dependency on XENBUS_DEVICE* pointers in the XenHypercall() prototypes - moving the discovered hyperpage address to a global variable - moving XenGetSharedInfoPage() to its only user XenBusDxe.c (the shared info page is not strictly part of the Xen hypercall interface, and is not used by other expected users of XenHypercallLib such as the Xen console version of SerialPortLib - reimplement XenHypercall2() in C and move the indexing of the hyperpage there; the existing asm implementations are renamed to __XenHypercall2() and invoked from the new C implementation.

This patch replaces the type of Len in WRITE_REQUEST and the type of the argument Len of XenStoreWriteStore and XenStoreReadStore. This patch should avoid to have type cast were it does not make sense to have them.

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.

It will look for advertised ParaVirtualized devices and initialize them by producing XenBus 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.
