Embodiment Construction
[0045] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments It is only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0046] In the PCIe bus, MSI and MSIX interrupts are heavily used. When the PCIe device has an event and needs to be serviced by the host software, the PCIe device sends an interrupt message to the host using the MSI or MSIX mechanism. This message is based on standard PCIe memory Write TLP packets, which are routed ...

The application discloses an interrupt message processing method, device, electronic equipment, and computer-readable storage medium, and relates to the field of computer technology. The method is applied to an interrupt message receiver, the interrupt message receiver is connected to a target bus, and the target bus is connected to a host computer and a host computer. The target device is connected, and the method includes: if the interrupt processing request sent by the host is obtained from the target bus, then determine the interrupt address space; if the interrupt message sent by the target device is obtained from the target bus, then respond to the interrupt message; wherein, the interrupt message The write destination address of the device is in the interrupt address space; by determining the interrupt address space, the target device is allowed to use the interrupt address space to send an interrupt message to the interrupt message receiver, and complete the transfer of the interrupt message from the host to the interrupt message receiver, and the interrupt message receiver To process the interrupt message, the processing speed of the interrupt message can be improved and the delay can be reduced.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a method for processing an interrupt message, an apparatus for processing an interrupt message, an electronic device, and a computer-readable storage medium. Background technique [0002] In PCIe (Peripheral component interconnect express) bus, MSI (MessageSignalled Interrupts) and MSIX (MSI extension) interrupts are widely used. When the PCIe device has an event and needs to be serviced by the host software, the PCIe device sends an interrupt message to the host using the MSI or MSIX mechanism. Correspondingly, there is a specific memory space on the PCIe space on the host side. When a memory write request falls into this space, the corresponding interrupt will be activated. The computing resources that the host can use to process interrupt messages are limited, and the processing speed has an upper limit, so the problem of slow and prolonged interrupt message ...
