2015-03-03OvmfPkg: replace strict XenHypercallLib construction with explicit queryLaszlo Ersek
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.

2015-02-28Ovmf/Xen: port XenBusDxe to other architecturesArd Biesheuvel
This patch updates XenBusDxe to use the 16-bit compare and exchange function that was introduced for this purpose to the BaseSynchronizationLib. It also provides a new generic implementation of TestAndClearBit () using the same 16-bit compare and exchange, making this module fully architecture agnostic.

2015-02-28Ovmf/Xen: move XenBusDxe to abstract XENIO_PROTOCOLArd Biesheuvel
While Xen on Intel uses a virtual PCI device to communicate the base address of the grant table, the ARM implementation uses a DT node, which is fundamentally incompatible with the way XenBusDxe is implemented, i.e., as a UEFI Driver Model implementation for a PCI device.

This moves all of the Xen hypercall code that was private to XenBusDxe to a new library class XenHypercallLib. This will allow us to reimplement it for ARM, and to export the Xen hypercall functionality to other parts of the code, such as a Xen console SerialPortLib driver.

2015-02-28Ovmf/Xen: refactor XenBusDxe hypercall implementationArd Biesheuvel
This refactors the Xen hypercall implementation that is part of the XenBusDxe driver, in preparation of splitting it off entirely into a XenHypercallLib library. 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.

2015-02-28Ovmf/Xen: fix pointer to int cast in XenBusDxeArd Biesheuvel
On ARM, xen_pfn_t is 64 bits but the size of a pointer is only 32 bits, so casting between them needs to go via (UINTN). Also move the xen_pfn_t cast outside the shift so that we can avoid shifting 64-bit quantities on 32-bit architectures, which may require runtime library support.
