* OvmfPkg/XenHypercallLib: Enable it in PEIMAnthony PERARD2019-08-213-9/+19
| | | | | | | | | | | | | | | Allow to use Xen hypercalls earlier, during the PEIM stage, but XenHypercallLibInit() must be called once the XenInfo HOB is created with the HyperPage setup. Change the return value of XenHypercallLibInit so failure can be detected when the call shouldn't fail, but still have the constructor always succeed.

* OvmfPkg/XenHypercallLib: enable virt extensions for ARMArd Biesheuvel2017-11-172-0/+5
| | | | | | | | | | | | | | | | | | | | XenHypercallLib uses the 'hvc' instruction, which is not implemented on all ARMv7 CPUs, and so we need to explicitly specify a CPU that has the virtualization extensions. This override used to be set at the platform level, but this was removed in commit 0d36a219c7bdbb27d775b50837823b2a9928147c ('ArmPlatformPkg/PL031RealTimeClockLib: drop ArmPlatformSysConfigLib reference), under the assumption that all users of the 'hvc' instruction had already been fixed. So fix this for GNU binutils by adding the 'virt' arch extension directive, and for RVCT by setting the --cpu command line option to a CPU that is virt capable.

| | | | | | | | | | | | | | GCC_ASM_EXPORT() not only exports a symbol as a function, it also emits a .type <xxx>, %function directive, which is used by the ARM linker to decide whether to emit interworking branches. So replace the explicit .global with GCC_ASM_EXPORT(), or the code will not be callable from Thumb-2 code.

* OvmfPkg: replace strict XenHypercallLib construction with explicit queryLaszlo Ersek2015-03-031-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* OvmfPkg: XenHypercallLib: add empty constructor for ARM & AARCH64Laszlo Ersek2015-03-032-1/+29
| | | | | | | | | | | | | | | | | | | | In the next patch we'll add a simple query function to the XenHypercallLib library class that is supposed to be called by initialization code in modules. Among those, in constructors of dependent libraries too. Library construction ordering is ensured only between libraries with constructors, plus we shouldn't allow a dependent library with a constructor to call into any XenHypercallLib instances (the simple query function) before XenHypercallLib is constructed itself. For this reason, introduce an (empty) constructor for ARM & AARCH64 too.

* Ovmf/Xen: move XenBusDxe hypercall code to separate libraryArd Biesheuvel2015-02-285-0/+243
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.
