Embodiment 1

[0073] figure 1 It is a flow chart of the interrupt processing method provided by Embodiment 1 of the present invention, such as figure 1 As shown, it specifically includes the following steps:

[0074] Step 101, the BMC receives the interrupt trigger signal sent by the logic device, and the interrupt trigger signal is sent by the logic device when it detects that the server fails;

[0075] Step 102, BMC reads the interrupt information corresponding to the fault from the interrupt register of the logic device;

[0076] Step 103, the BMC performs interrupt processing according to the interrupt information, and clears the interrupt information corresponding to the processed interrupt in the interrupt register after the interrupt processing is completed.

[0077] Specifically, after a server fails, the logic device can collect the failure information of the server and store it in the interrupt register of the logic device in the form of an interrupt, and send an interrupt trigg...

Embodiment 2

[0089] figure 2 The flow chart of the interrupt processing method provided by Embodiment 2 of the present invention, such as figure 2 As shown, it specifically includes the following steps:

[0090] Step 201, the logic device detects that the server fails;

[0091] Step 202, the logic device sends an interrupt trigger signal to the BMC;

[0092] Step 203, the logic device sends the interrupt information corresponding to the fault read by the BMC from the interrupt register of the logic device to the BMC;

[0093] Step 204: After the BMC completes the interrupt processing, the logic device clears the interrupt information corresponding to the processed interrupt in the interrupt register.

[0094] Specifically, when the logic device detects that the server fails, the logic device will send an interrupt trigger signal to the BMC through the GPIO to trigger the BMC to process the interrupt. After the BMC is triggered, the logic device will send the BMC slave logic to the BMC...

Embodiment 3

[0105] This embodiment is a specific description of the interrupt processing method in combination with Embodiment 1 and Embodiment 2. image 3 The flow chart of the interrupt processing method provided by Embodiment 3 of the present invention, such as image 3 As shown, in combination with Embodiment 1 and Embodiment 2, the specific implementation scheme of the present invention includes the following steps:

[0106] Step 301, start the BMC, and set the interrupt pull-up register to 1;

[0107] Set the interrupt pull-up register to 1, indicating that the BMC is ready to receive and process interrupt trigger signals from logic devices;

[0108] Step 302, query interruption, if an interruption occurs, execute step 303, if there is no maintenance query;

[0109] Step 303, the logic device sends an interrupt trigger signal to the BMC;

[0110] When an interrupt is generated, the logic device will pull down or pull up the GPIO signal line to trigger the BMC. For the trigger si...

Abstract

The invention discloses an interrupt processing method, device and system. The interrupt processing method includes: a baseboard management controller (BMC) receives an interrupt triggering signal transmitted by a logic device when the logic device detects a fault of a server; the BMC reads interrupt information corresponding to the fault from an interrupt register of the logic device; the BMC performs interrupt processing according to the interrupt information and clears the interrupt information in the interrupt register. By changing sequence of related interrupt processing, interrupt processing is executed prior to interrupt clearing, interrupt loss can be avoided.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an interrupt processing method, device and system. Background technique [0002] With the increasing popularity of high-end fault-tolerant computers, users have put forward higher and higher requirements for the reliability of computer operation. When a server fails or an alarm occurs, the server will notify the Baseboard Management Controller (BMC for short) in the form of an interruption, and the BMC will handle the interruption after receiving a response, so that the normal operation of the server will not be affected. [0003] In the existing interrupt processing technology, the logic device detects the running status of the server. When an interrupt is generated, the logic device triggers the BMC through the General Purpose Input Output (GPIO for short), and the BMC receives the interrupt, and then reads the status of the logic device. The interrupt re...
