Description
Technical field
The present invention relates to computer realm, more particularly to a kind of method for testing PCIe card warm connection function.
Background technology
PCI-Express (peripheral component interconnect express) is a kind of high speed serialization
Computer expansion bus standard, its original entitled " 3GIO " are to be proposed by Intel in 2001, it is intended to substitute old
PCI, PCI-X and AGP bus standard.PCIE belongs to the point-to-point binary channels high bandwidth transmission of high speed serialization, the equipment connected point
With bandwidth chahnel is exclusively enjoyed, bus bandwidth is not shared, mainly supports active power management, error reporting, end-to-end reliability passes
It is defeated, the functions such as hot plug and service quality (QOS).PCIE transfers to ability after PCI-SIG (PCI particular interests tissue) certification issue
It is renamed as " PCI-Express ", referred to as " PCI-E ".Its main advantage is exactly message transmission rate height, highest at present
16X2.0 versions can reach 10GB/s, and also sizable development potentiality.
In server architecture system, PCIE is the external apparatus interface of standard, and net can be expanded by PCIE interfaces
Card, video card, storage card multiple standards PCIE device.PCI Express support the characteristic of hot plug and heat exchange, that is to say, that
You can replace the version card of PCI Express slots and various hardware devices in the case where that need not close system and power supply.
And hot plug measuring technology mainly relies on the progress of hot plug testing scheme, supports the module of hot plug, to test
For plug repeatedly be test pain spot, how to carry out fast and effectively testing scheme, to the shortening Time To Market of product,
Ensure that product quality plays a crucial role.
The content of the invention
The present invention is achieved through the following technical solutions, and a kind of test method of PCIe card warm connection function utilizes master
BMC module in plate gives system transmitting order to lower levels, hot plug testing process is simulated by software, to test warm connection function.
Preferably, buffer status in each Plug Action PLX chips is also collected in this method.
The present invention also provides a kind of test methods of PCIe card warm connection function, include the following steps, 1) basis first
BDF where the corresponding PCIE switch chips in PCIe card slot position checks the state of corresponding groove position hot plug related register；2)
Cmd interfaces, which are provided, according to bmc realizes that single step works in hot plug flow.
Further, step 2) further comprises being inserted into flow and extracts flow.
Further, the insertion flow in step 2) includes the control release of insertion button, BMC.
Further, the extraction flow in step 2) includes deleting the control release of button, deletion MRL and prsnt, BMC.
The present invention provides a kind of computer-readable medium, is stored thereon with computer program, which is executed by processor
To realize the method.
The present invention also provides a kind of computer equipment, on a memory and can locate including memory, processor and storage
The computer program run on reason device, the processor perform described program to realize the method.
The present invention is to test hot plug flow by software simulation, reduce object compared with the advantageous effect of the prior art
The injury that reason plug is brought to connector.Hot plug register related register can be collected by the testing scheme, utilize foot
This progress hot plug test can be completed to test at any time, and physics plug is not required, improves testing efficiency.
Description of the drawings
What Fig. 1 one embodiment of the invention provided provides related command schematic diagram by bmc
The flow diagram for the test PCIe card warm connection function that Fig. 2 one embodiment of the invention provides
Specific embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings.Following embodiment is only used for clearer
Ground illustrates technical scheme, and is not intended to limit the protection scope of the present invention and limits the scope of the invention.
In the embodiment of the present invention, as shown in Figure 1, providing the order of related command PCIE Hot-Plug control interfaces such as by bmc
Under：
1. it is powered on to PCIE slots, the order of lower electricity；2nd, set, remove the order of MRL；3rd, the insertion of software simulation heat and heat
The order of extraction；4th, software can be pressed operation with analog buttons；5th, software can set and remove the signal in place of IO cards.
As shown in Fig. 2, flow is as follows in one embodiment of the invention：
1) BDF first according to where the corresponding PCIE switch chips in PCIe card slot position, can check corresponding groove position heat
Plug the state of related register.Mainly it is embodied as code below：
It is posted for example, test script reads 1 slot position slot status register command completed bit20
Storage value (test result 0, the state update of expression are completed)
2) cmd interfaces are provided according to bmc and realizes that single step works in hot plug flow.
Flow is inserted into be completed by two orders：
1.Insertion Button：
./ipmitool-H 127.0.0.1-U admin-P admin raw 0x30 0x34 0x00 0xf4
2.Release BMC control：
./ipmitool-H 127.0.0.1-U admin-P admin raw 0x30 0x34 0x00 0x00
Flow is extracted to be completed by three orders
Remove：
1.Remove Button：
./ipmitool-H 127.0.0.1-U admin-P admin raw 0x30 0x34 0x00 0xf8
wait for Data link down.
2.Remove MRL&&prsnt：
./ipmitool-H 127.0.0.1-U admin-P admin raw 0x30 0x34 0x00 0xc8
