[ detailed description ] embodiments
Fig. 1 is a block diagram of a server 100 according to an embodiment of the invention. The server 100 includes a nonvolatile storage unit 110, a control unit 120, a Baseboard Management Controller (BMC) 130, and a control chipset 140. The nonvolatile memory unit 110 may be a nonvolatile memory such as an Electrically Erasable Programmable Read Only Memory (EEPROM), a flash memory, etc. The control unit 120 may be an arithmetic unit such as a Complex Programmable Logic Device (CPLD), a microcontroller, or the like. The control chipset 140 may be a control chip such as a Platform Controller Hub (PCH) or a south bridge chip for connecting the i/o devices. The control unit 120 and the control chip set are coupled to the nonvolatile storage unit 110. Herein, the control unit 120 and the control chipset are coupled to the non-volatile storage unit 110 via a System Management Bus (SMB), but the embodiment of the present invention is not limited thereto. The control unit 120 includes a number of pins 121. The bmc 130 includes one or more pins 131, and the control chipset 140 includes one or more pins 141, wherein the pins 131, 141 are coupled to the pins 121 of the control unit 120 in a one-to-one manner.
Although the pin 131 of the bmc 130 is coupled to the pin 121 of the control unit 120 and the pin 141 of the control chipset 140 is coupled to the pin 121 of the control unit 120, in some embodiments, only the pin 131 of the bmc 130 may be coupled to the pin 121 of the control unit 120 to perform initialization setting for the bmc 130; or only the pin 141 of the control chipset 140 is coupled to the pin 121 of the control unit 120 for performing initialization setting with respect to the control chipset 140.
Fig. 2 is a flowchart of a boot initialization method for the server 100 according to an embodiment of the invention. The individual steps of the method are described in detail below.
In step S210, a storage initialization is set in the nonvolatile storage unit 110. In other words, the nonvolatile storage unit 10 can be used for storing initialization settings.
In step S220, the control unit 120 obtains the stored initialization setting from the non-volatile storage unit 110. The initialization setting specifies the voltage level that each pin 121 should output. The voltage levels may correspond to logic variables, such as: a high voltage level (e.g., 3 volts) corresponds to a logic true, and a low voltage level (e.g., 0 volts) corresponds to a logic false. The voltage level may also correspond to a nominal voltage value, i.e., a certain pin 121 maintains an output of a specific voltage level (e.g., 3.3 volts, 5 volts), which may be the aforementioned high voltage level, low voltage level, or a voltage value therebetween.
In step S230, the control unit 120 outputs a corresponding voltage level at each pin 121 according to the read initialization setting according to actual requirements. For example, if the bmc 130 is to be initialized, the control unit 120 outputs a required voltage level at the pin 121 coupled to the pin 131 of the bmc 130; if the control chipset 140 is to be initialized, the control unit 120 outputs a required voltage level at the pin 121 coupled to the pin 141 of the control chipset 140. For example, the pins 141 required for initializing the chip set 140 may be, for example, the "No rebot" pin, the "Top-Block switch over" pin, and the "Boot BIOS Strap" pin, which are available from Intel corporation as the C216 chip.
In step S240, the bmc 130 or/and the control chipset 140 receives the voltage levels outputted by the pins 121 of the control unit 120, and performs an initialization operation according to the voltage levels. Therefore, at least one of the bmc 130 and the control chipset 140, that is, the bmc 130 or/and the control chipset 140 may receive the voltage levels (i.e., the parameter settings required for initialization) output by the pins 121 before the initialization itself, and may perform the initialization operation according to the voltage levels.
In this embodiment, in step S210, the initialization setting written in the non-volatile storage unit 110 may be an original parameter setting, or an updated parameter setting of an old initialization setting already stored in the non-volatile storage unit 110.
In this embodiment, the server 100 may execute the write initialization setting, i.e. the initialization setting is written into the nonvolatile storage unit 110 through the control chipset 140.
Fig. 3 is a block diagram of a server 100 according to another embodiment of the invention. The difference between the embodiment shown in fig. 1 is that the server 100 of the present embodiment further includes a communication interface 150 coupled to the non-volatile storage unit 110. Accordingly, the non-volatile storage unit 110 can receive the initialization setting transmitted by the updating apparatus 300 through the communication interface 150 and store the received initialization setting. The communication interface 150 may support the system management bus, but the embodiment of the invention is not limited thereto. The update device 300 may be an electronic device such as a mobile phone, a personal computer, a notebook computer, a tablet computer, and the like.
Fig. 4 is a block diagram of a server 100 according to another embodiment of the present invention. The difference between the embodiment shown in fig. 1 is that the server 100 of the present embodiment further includes a network interface 160 connected to the bmc 130. The bmc 130 receives the initialization setting transmitted by the update apparatus 300 via the network interface 160. Therefore, the bmc 130 may issue an instruction to the control chipset 140 to perform control, so as to write the received initialization setting into the non-volatile storage unit 110 through the control chipset 140. Specifically, when the initialization setting is to be transmitted, the bmc 130 first sends an interrupt signal to the control chipset 140, so that the control chipset 140 suspends the current execution and obtains the initialization setting from the bmc 130. The control chipset 140 then writes the initialization setting into the non-volatile storage unit 110. Here, the communication between the bmc 130 and the control chipset 140 conforms to a Low Pin Count (LPC) bus protocol. In this embodiment, the communication between the bmc 130 and the control chipset 140 may also be a system Management bus (bmc) or an Intelligent Platform Management Interface (IPMI).
In the present embodiment, the control unit 120, the bmc 130 and the control chipset 140 further include other pins besides the pins 121, 131 and 141, which are not required for initializing the bmc 130 or/and the control chipset 140, and are not specifically shown and described herein. In other words, the pins 121, 131, and 141 are only pins required for performing initialization operations on the bmc 130 or/and the control chipset 140, and the control unit 120, the bmc 130, and the control chipset 140 further include pins for performing other controls (e.g., power-on control of other chips). Furthermore, the control chipset 140 can also read other settings from the non-volatile storage unit 110 and program the states of other pins according to the settings to achieve control for other purposes.
Fig. 5 is a block diagram of a server 100 according to yet another embodiment of the invention. The difference between the foregoing embodiments is that the server 100 of the present embodiment has both the communication interface 150 and the network interface 160, so that the updating apparatus 300 can select to transmit the initialization setting through the communication interface 150 or through the network interface 160.
In summary, according to the server 100 and the power-on initialization method thereof provided by the embodiment of the invention, the control unit 120 can provide the parameter settings required for initializing the bmc 130 and the control chipset 140 through a software manner, so as to save the hardware cost of the conventional hardware mode, shorten the setting time, and avoid human misoperation.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and shall cover the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
