Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
According to an embodiment of the present application, there is provided an embodiment of a control method for an expansion card, it should be noted that the steps shown in the flowchart of the drawings may be executed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that here.
Fig. 1 is a flowchart of a method for controlling an expansion card according to an embodiment of the present application, and as shown in fig. 1, the method includes the following steps:
step S102, controlling the power-off of an expansion card interface under the condition that the expansion card is not inserted into the expansion card interface of the equipment;
it should be noted that the expansion card interface is a PCIE interface, and the expansion card is hereinafter collectively referred to as a PCIE network card.
Step S104, after a first instruction for inserting the expansion card into the expansion card interface is obtained, controlling the expansion card to be inserted into the expansion card interface;
and step S106, loading the driving software for driving the expansion card under the condition that the expansion card inserted into the expansion card interface is normally powered on.
Through the steps, the purpose that the PCIE interfaces of the related equipment support the hot plug function of the PCIE interfaces is achieved, so that the technical effects that the labor maintenance cost when the PCIE interfaces plug the expansion card is reduced, and the maintenance convenience of the PCIE interfaces is enhanced are achieved.
According to an alternative embodiment of the present application, the step S102 of controlling the expansion card interface to power off is executed, which includes the following steps: transferring the control right of the expansion card interface to the expansion card from the central processing unit to the substrate management controller; the power of the card interface is expanded through the substrate management controller; and after the power of the expansion card interface is cut off, the control right of the expansion card interface to the expansion card is transferred to the central processing unit from the substrate management controller.
It should be noted that, when the device is powered on, each slot (i.e., the above expansion card interface) is powered on by default, software is used to scan whether a PCIE network card is inserted into each slot, if not, an instruction is sent out, the PCIE control right of the slot is transferred to a Baseboard Management Controller (BMC), the BMC sends an instruction to the BMC through the software, the BMC controls the slot to be powered off, so that the default of the slot into which the PCIE network card is not inserted is not powered off, and the PCIE control right is returned to a Central Processing Unit (CPU) after the power off.
Table 1 is detailed information of a main board PCIE expansion slot/line card signal provided in the embodiment of the present application, as shown in table 1 below:
table 1 mainboard PCIE expansion slot/line card signal
The power supply enabling, resetting, on-site detection and GPIO keys of the line cards are all extended by PCA9555(I2C changes 16 paths of GPIO), the PCA9555 is in a default state after being powered on, and each IO is in an internal 100K pull-up input state. PCA9555 uses the P3V3_ SLOT power domain (i.e., PCA9555 is inaccessible if the CPU is off).
Table 2 is a truth table for line card power enable control, as shown in table 2:
| PRSNT_N | PCA9555_PWR_EN | P12_EN/P3V3_EN | P3V3SB_EN |
| 0 (in place) | 0(BMC control switch) | 0 | 0 |
| 0 (in place) | 1(BMC control switch) | Rear 1 | First 1 |
| 1 (out) | 0(BMC control switch) | 0 | 0 |
| 1 (out) | 1(BMC control switch) | 0 | 0 |
| 0 plug-in card power-on | 1(BMC uninitialized) | Back 1 (without time delay) | First 1 (without time delay) |
| 1- > 0 (Hot insertion) | 1(BMC uninitialized) | Back 1 (with time delay) | First 1 (with time delay) |
The key to the processing is that if the line card is powered on in the plugged state, there should be no delay on the line card. If the line card is hot-plugged, the line card should have a delay protection.
If there is a delay in booting in the plugged-in state, it may be too long for the BIOS to correctly identify the device.
If the thermal insertion delay is too short, the gold finger is likely to generate a large thermal effect when the contact is poor.
Before BMC starting is completed, line card power supply can be controlled through PRSNT _ N, and the PRSNT _ N has higher priority.
The general design idea is that when the PRSNT _ N signal bit is 0 and the PCA9555_ PWR _ EN signal controlled by the BMC is 1, each power supply of the line card needs to be controlled to be powered on, and P3V3SB needs to be powered on first. In other states, the line cards are powered down. The delay circuit is active when PRSNT _ N is from 1- > 0, but no delay is needed when PRSNT _ N is kept at 0 all the time. The POWER SWITCH can select the chip with soft start and overcurrent protection, and in general, the line CARD P12V _ CARD uses the POWER SWITCH of 2-3A, the P3V3_ CARD uses the POWER SWITCH of 2-3A, and the P3V3SB _ CARD uses the POWER SWITCH of 1A. The BYPASS _ EN/GATE _ SLOT signal needs to be isolated by using a tri-state buffer, which supplies P3V3BY _ SLOT, so that the BYPASS signal can still be maintained for a practical period when the host is powered down. After the line CARD is removed, the signals are in a high-impedance state, and when the line CARD is inserted, the P3V 3-12V _ CARD _ EN signal controls enabling. The BYPASS signal requires a current limiting resistor if a buffer design is not used.
According to another alternative embodiment of the present application, the step S104 of controlling the expansion card to be inserted into the expansion card interface is executed, and includes: and controlling the expansion card to establish connection with the expansion card interface.
In this step, the expansion card is inserted into the expansion card interface, which is to essentially establish a connection relationship between the expansion card and the expansion card interface.
In some optional embodiments of the present application, before the step S106 is executed to load the driver software for driving the expansion card, the control right of the expansion card interface to the expansion card needs to be transferred from the central processing unit to the baseboard management controller; and controlling the expansion card to reset and power on through the baseboard management controller.
Optionally, after loading the driver software for driving the expansion card, the control right of the expansion card interface to the expansion card is transferred from the baseboard management controller to the central processor.
After receiving an instruction of inserting the expansion card into the slot position, sending the PCIE control right of the slot position to the BMC, sending an instruction to the BMC to control the GPIO to power on and reset the PCIE card, scanning the PCIE card by a system, loading a drive by the system, confirming that the PCIE network card is normally powered on, confirming that a network interface indicator lamp is normal, and confirming that the PCIE network card is normally inserted. At this point, the PCIE control right is handed back to the CPU.
In other alternative embodiments of the present application, the step S102 of obtaining a first instruction for inserting an expansion card into an expansion card interface is executed, including one of the following manners: acquiring a first instruction issued through a software interface; and acquiring a first instruction issued by clicking a hardware button on the equipment.
In the embodiment provided by the application, there are two types of PCIE network cards, one is a PCIE network card without a BTN button, and the other is a PCIE network card with a BTN button.
The difference between the two expansion cards inserted into the relevant equipment through the PCIE interface is that when the PCIE network card without the BTN button is inserted, an instruction for inserting the PCIE network card is issued through a software interface; when the PCIE network card with the BTN button is inserted, the command for inserting the PCIE network card is issued by clicking the BTN button, specifically, the BTN button is pressed, GPIO is controlled through the BTN, OS scans the change of the GPIO controlled by the BTN, the PCIE control right of the slot position is sent to BMC, and the command is issued to inform the BMC to enable the PCIE card to be powered on and reset. And the other steps of inserting the PCIE network card are consistent.
In an alternative embodiment, a button (BTN button) is connected to the PCA9555, and the software can trigger the operation of pulling out the line card according to the pulling down of the button for a long enough time (e.g., 3 seconds). The software can trigger this key status query using the INT signal of PCA 9555. If the line card does not have an indicator light to reflect the power supply of the line card is in the power-off state, a power indicator light needs to be additionally designed, and a user can judge whether the line card can be safely plugged according to the indicator light.
Fig. 2 is a flowchart of another control method of an expansion card according to an embodiment of the present application, and as shown in fig. 2, the method includes the following steps:
step S202, after a second instruction for pulling out the expansion card from the expansion card interface of the equipment is obtained, the driving software for driving the expansion card is unloaded;
in this step, the driving software for driving the PCIE network card is unloaded when an instruction to pull out the PCIE network card is received.
Step S204, controlling the expansion card to be powered off;
and step S206, after determining that the expansion card is powered off, controlling the expansion card to be pulled out from the expansion card interface.
According to an alternative embodiment of the present application, the step S204 is executed to control the expansion card to power off, which includes the following steps: transferring the control right of the expansion card interface to the expansion card from the central processing unit to the substrate management controller; and powering off the expansion card through the baseboard management controller.
In this step, the PCIE control right of the slot where the PCIE network card is pulled out is given to the BMC, and an instruction is issued to the BMC to control the GPIO so that the PCIE network card is powered off.
According to an alternative embodiment of the present application, executing step S206 to control the expansion card to be pulled out from the expansion card interface includes: and controlling the expansion card to be disconnected with the expansion card interface.
In the above, the expansion card is inserted into the expansion card interface, and the connection relationship between the expansion card and the expansion card interface is essentially established. Accordingly, the expansion card is pulled out of the expansion card interface, and the connection relationship between the expansion card and the expansion card interface is substantially broken.
In some optional embodiments of the present application, after the step S206 is executed to control the expansion card to be pulled out from the expansion card interface, the control right of the expansion card interface to the expansion card needs to be transferred from the baseboard management controller to the central processing unit.
In this step, the network interface indicator light of the PCIE network card is turned off, it is determined that the PCIE card is not charged, the network card is pulled out, and the control right of the PCIE network card by the PCIE interface is handed back to the CPU.
