According to an embodiment of the present invention, a method and apparatus for multi-processor systems inter-processor interrupt it is described. 实施方案包括将处理器间中断请求写入第一存储位置;监视第一存储位置;在第一存储位置中检测处理器间中断请求;调
The first restriction on processor access is one of the following two types: (i) disabling the interrupts on a given processor; and/or (ii) sending inter-processor interrupts with synchronous waiting from one processor to another (including itself).Srivatsa S. Bhat...
In addition to the 16 IPC channels, PSoC 6 also provides 16 IPC interrupts. Each IPC interrupt can be used as event triggers from one core to another. This mechanism can be used in conjunction with an IPC channel to set up a messaging scheme with a notification event and acknowledgement....
I am using imx6 sabrelite board in which #Linux OS running on core0 and #RTOS on core2. My task is to establish inter-processor communication between two operating systems. My idea is to create shared memory section and allow read-write access using Software Generated Interrupts(SG...
Pass-through of the local APIC means that the VMM need not trap and emulate the functioning of the local APIC (e.g., via virtualization of the local APIC) for the VM to send inter-processor interrupts (IPIs) to core(s) on which the VM is executing. In order to provide such pass-...

A data processing system includes, in one embodiment, at least a first processor and a second processor and an interrupt controller, and the system provides a deferred inter-processor interrupt (IPI) that can be used to wake up the second processor from a low power sleep state. The deferred...

In one aspect, a hardware device for delivering inter-processor interrupts is provided. The hardware device includes a memory having a memory space that corresponds to a virtual memory space of a first guest process and a controller coupled to the memory. The controller may be configured to ...
Embodiments of apparatuses, methods, and systems for virtualization of interprocessor interrupts are disclosed. In an embodiment, an apparatus includes a plurality of processor cores; an interrupt controller register; and logic to, in response to a write from a virtual machine to the interrupt ...
