Problems solved by technology

At present, some functions of GPIO settings can be tested, but most of the functions may not have corresponding functional test cases. When verifying the configuration, it is generally read through tools, and manually check the GPIO configuration one by one.
However, there are many GPIOs in the PCH. Manual inspection is time-consuming and error-prone, and can only be inspected by developers. The test cannot fully cover the functional test, and it is prone to functional abnormalities caused by GPIO configuration errors.

Embodiment 1

[0042] Such as figure 1 As shown, the present embodiment provides a GPIO configuration detection method, comprising the following steps:

[0043] S1, initialize each GPIO and hardware;

[0044] S2, read the pin logic of each GPIO in turn;

[0045] S3, comparing the read pin logic with the standard logic in the pre-stored logic detection table, and judging whether the two are consistent;

[0046] S4, outputting the comparison result, if the two are consistent, the GPIO configuration is normal, otherwise the GPIO configuration is abnormal.

[0047] This method first pre-stores the logic detection table, which stores the pin standard logic of each GPIO. After reading the pin logic of each GPIO, the configuration of the GPIO is automatically detected by matching and comparing with the standard logic in the table. No need for manual inspection, improve detection efficiency.

Abstract

The invention discloses a GPIO (General Purpose Input / Output) configuration detection method and device and a server. Firstly, each GPIO and hardware are initialized; after initialization, pin logics of all GPIOs are read in sequence; the read pin logic is compared with standard logic in a pre-stored logic detection table, and whether the read pin logic and the standard logic are consistent or not is judged; and a comparison result is output, if the read pin logic and the standard logic are consistent consistent, determining that the GPIO configuration is normal, otherwise, determining that the GPIO configuration is abnormal. According to the method and device, a logic detection table is pre-stored, pin standard logic of GPIO is stored in the table, a machine is started to automatically collect pin information of GPIO, the collected information is matched with the pre-stored standard logic, automatic detection is carried out, and a detection result is obtained and output. According to the method, and device, the correctness of the GPIO configuration in the current PCH can be obtained, the testability of the GPIO function is enhanced, the test integrity is perfected, and the detection efficiency is effectively improved.

Description

technical field [0001] The invention relates to the field of GPIO configuration detection, in particular to a GPIO configuration detection method, device and server. Background technique [0002] With the upgrade of server PCH chips, more and more GPIOs of PCH are added. The setting of GPIO is determined by the hardware. In the startup phase, a single GPIO is configured according to the hardware design, and the Native function or GPIO function is selected. Taking the GPIO function as an example, the GPIO function is configured as input and output signals, and the number of configured input and output signals depends on the hardware configuration. When configured as an output signal, it can be configured as a high level or a low level, and the path bit of the GPIO allows input of an SMI (system control interrupt), SCI (system management interrupt) or NMI (non-maskable interrupt) interrupt, each bit Can be used as the path of SMI or SCI, some registers of GPIO can be changed...
