Problems solved by technology

[0007] However, the protocol analyzer equipment is expensive, and now PCIe is updated very quickly, and the instrument also needs to be updated, which increases the cost of research and development investment.
Secondly, when using the protocol analyzer, it is necessary to purchase not only the instrument but also the fixture. The fixture is easy to be damaged when plugged and pulled out, and the price is expensive and maintenance is troublesome.
In addition, the use of protocol analyzers requires long-term training and entry, which puts forward new learning requirements and training requirements for R&D personnel
Moreover, the current test card supporting the protocol analyzer has only one interface, while the PCIe device has a variety of interface types, some high-speed interfaces do not match the test card, resulting in unusable
Or there is no physical interface between the two terminals, and the communication and negotiation are carried out directly through the transmission line, which makes it impossible to insert the card.

Embodiment Construction

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] The current existing technology is to use a protocol analyzer to analyze the entire dynamic equalization negotiation process of the PCIe device. In the mainstream protocol analyzers on the market, in addition to the instrument itself, it is also necessary to purchase a matching test card. This card is installed between the master device and the slave device at both ends of the PCIe signal to analyze the negotiation and equalizat...

Abstract

The invention discloses a PCIe device dynamic equilibrium stage monitoring method and device, equipment and a medium, and relates to the technical field of computers, and the PCIe device dynamic equilibrium stage monitoring method comprises the steps that data reading is carried out on a dynamic equilibrium state register pre-integrated in a PCIe device, and target register data corresponding to a current dynamic equilibrium stage of the PCIe device is read from the dynamic equilibrium state register; querying a preset mapping relation library by using the target register data so as to query a target stage indication mode corresponding to the target register data from the mapping relation library; and screening out a target indicator lamp from an indicator lamp group pre-integrated in the PCIe equipment, and controlling the target indicator lamp to display according to the target stage indication mode. According to the technical scheme, the situation that the dynamic equilibrium state of the current PCIe equipment can be known by means of a protocol analyzer is avoided, so that the equipment research and development investment cost, the maintenance cost and the user learning cost are greatly saved, and the complex equipment operation process is avoided.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a method, device, device and medium for monitoring a dynamic equalization phase of a PCIe device. Background technique [0002] PCIe (ie Peripheral Component Interconnect express, high-speed serial computer expansion bus standard) is the third generation I / O bus after ISA (ie Industry Standard Architecture, industry standard architecture) and PCI bus. Its main advantages are high data transmission rate, strong anti-interference ability, long transmission distance and low power consumption. [0003] Starting from PCIe 3.0, the PCI-SIG (Peripheral Component Interconnect Special Interest Group, Peripheral Component Interconnect Special Interest Group) proposed the concept of dynamic equalization (ie Dynamic Equalization), which is also used in PCIe 4.0, PCIe 5.0, and PCIe 6.0. Next, take PCIe 3.0 as an example to introduce the concept and process of equalization: ...
