    摘要: An embodiment of the present invention is a technique to process an input/output (I/O) transaction. An emulated device driver in a guest partition interacts with a virtual machine (VM) manager in processing an input/output (I/O) transaction on behalf of an application via an operating system (OS). The I/O transaction is between the application and a device. A device emulator in a service partition communicatively coupled to the emulated device driver interacts with the VM manager in processing the I/O transaction on behalf of a device specific driver via the OS. The device specific driver interfaces to the device.

    摘要: Provided are a method, system and program for effecting a processor operating mode change to execute device code. A processor receives a call while the processor is operating in a first mode, wherein the call is made to effect execution of device code to control a device. The processor determines whether the call is intended to change a processor operating mode from the first mode to a second mode. The state of the processor is selectively changed to a second mode in which the processor executes second mode instructions loaded in a protected section of memory inaccessible to an operating system in response to determining that the call is intended to change the processor operating mode. The second mode instructions execute the device code to control the device.

    摘要: Technologies for system management interrupt (“SMI”) handling include a number of processor cores configured to enter a system management mode (“SMM”) in response to detecting an SMI. The first processor core to enter SMM and acquire a master thread lock sets an in-progress flag and executes a master SMI handler without waiting for other processor cores to enter SMM. Other processor cores execute a subordinate SMI handler. The master SMI handler may direct the subordinate SMI handlers to handle core-specific SMIs. The multi-core processor may set an SMI service pending flag in response to detecting the SMI, which is cleared by the processor core that acquires the master thread lock. A processor core entering SMM may immediately resume normal execution upon determining the in-progress flag is not set and the service pending flag is not set, to detect and mitigate spurious SMIs. Other embodiments are described and claimed.

    摘要: An alternative boot methodology that begins with legacy-free firmware allows the peaceful coexistence of legacy-free and legacy option ROMs in a system. Legacy-free firmware provides a legacy-free boot path from system power up to operating system loading. This legacy-free boot path is independent of any legacy firmware. A legacy-free boot manager boots from an ordered list of OS loaders. If a legacy boot option is available, legacy-free drivers that have already been loaded may be stopped, and a legacy boot using legacy firmware may be initiated, without having to reboot the system.

    摘要: Systems and methods provide for emulating a host architecture in guest firmware. One aspect of the systems and methods comprises determining whether an emulated instruction would cause a transition into a legacy mode. A current execution context is converted into a legacy mode context, and the firmware emulator proceeds to a group of legacy mode instructions in a native mode for the processor. The firmware emulator detects an end instruction and converts the legacy context back to the guest firmware context.

    摘要: Methods, systems and computer program products are disclosed for enhanced system boot processing that is faster to launch an operating system, as certain devices such as user input hardware devices may not be initialized unless it is determined that a user-interruption to the boot process is likely. That is, although an interface for the devices is exposed, no initialization occurs unless a call to the interface occurs. Other embodiments are described and claimed.
