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.
In order to facilitate understanding of the solution of the present application, an ARM server applied to the hot reboot method of the PCI device is described, where the ARM server includes an ARM motherboard, and a structure of the ARM motherboard is shown in fig. 1, where the ARM motherboard includes an ARM processor and PCI slots with multiple bandwidths, including a PCI slot with a bandwidth of x16, a PCI slot with a bandwidth of x8, and a PCI slot with a bandwidth of x4, the ARM processor includes multiple GPIO signal interfaces, only 4 GPIO signal interfaces are shown in FIG. 1, the PCI slot with the bandwidth of x16 comprises 16 Reset signal interfaces, the 16 Reset signal interfaces are divided into 4 groups, each group comprises 4 Reset signal interfaces, the 4 GPIO signal interfaces are respectively correspondingly connected with the 4 groups of Reset signal interfaces, as shown in fig. 1, a PCI slot with a bandwidth of x16 may be split into two groups of PCI slots with a bandwidth of x8, four groups of PCI slots with a bandwidth of x4, or 1 group of PCI slots with a bandwidth of x8 and two groups of PCI slots with a bandwidth of x 4.
Referring to fig. 2, fig. 2 is a flowchart illustrating steps of a hot reboot method for a PCI device according to the present application, where the hot reboot method for the PCI device includes:
s101: acquiring GPIO state values of the PCI slots of each bandwidth, which are used for executing hot restart operation;
specifically, when the PCI slots with different bandwidths execute the warm reboot operation, the required GPIO state values are different, and in order to implement the subsequent warm reboot of the PCI devices in each PCI slot, the GPIO state values required for the PCI slots with each bandwidth to execute the warm reboot operation are first acquired.
It can be understood that the GPIO state value corresponding to the PCI slot of each bandwidth is adaptively adjusted according to the ARM server to which the PCI slot of x16 bandwidth belongs and the split state thereof, so that before executing this step, the method further includes the operation of obtaining the ARM server and the split state to which the PCI slot of x16 bandwidth belongs, and then determines, according to the split state of the PCI slot of x16 bandwidth and the ARM processor to which the PCI slot belongs, that the PCI slot of each bandwidth is used to execute the GPIO state value of the warm restart operation in the current split state.
Specifically, the GPIO state values of the PCI slots of each bandwidth used for the hot reboot operation may be set in advance according to actual engineering requirements, and as an optional embodiment, a GPIO state value table required by the PCI slots of x16 bandwidth in different split states and the PCI slots of each bandwidth corresponding to the PCI slots of x16 bandwidth may be created in advance, so that in the subsequent actual application, a target GPIO state value table may be determined according to the ARM server to which the PCI slots of x16 bandwidth currently belong and the split state, and the GPIO state value corresponding to the PCI slot of each bandwidth in the current split state may be determined according to the target GPIO state value table.
S102: determining the output state value of each GPIO signal interface according to the GPIO state value;
s103: and controlling each GPIO signal interface to output GPIO signals according to the corresponding output state value, and delaying preset time so as to warm restart the PCI equipment connected with each PCI slot with the bandwidth.
Specifically, the output state value of each GPIO signal interface may be determined according to the GPIO state value, and the output state value corresponding to each GPIO signal interface is controlled to output a GPIO signal to the Reset signal interface of the PCI slot with the corresponding bandwidth, so that the PCI device in the PCI slot with the triggered bandwidth performs a warm restart operation. It can be understood that, in this embodiment, each GPIO signal interface is controlled to output a GPIO signal according to the corresponding output state value and delay a preset time, so as to ensure that the PCI device can normally complete the warm restart operation, and the preset time may be determined according to the time required for a complete warm restart of the PCI device, and may be set to 100ms, for example.
For example, assuming that the GPIO state value required for the PCI slot of x16 bandwidth to perform a hot reboot operation is 0111, the output state values of GPIO1, GPIO2, GPIO3, and GPIO4 in fig. 1 are set to 0, 1, and 1, respectively.
Specifically, before executing this step, the method further includes an operation of determining whether there is a PCI device in a PCI slot of each bandwidth in the current splitting state, and if there is no PCI device in a PCI slot of a certain bandwidth, the output state values of the GPIO signal interfaces corresponding to the PCI slot of the bandwidth are not set, so that the PCI slot is kept in the default state.
As an alternative embodiment, the process of controlling each GPIO signal interface to output GPIO signals according to their respective output state values includes:
and simultaneously or sequentially controlling each GPIO signal interface to output GPIO signals according to the corresponding output state values.
Specifically, the output state values of the GPIO signal interfaces of the present embodiment may be set simultaneously or sequentially, and the pull-down setting may ensure signal synchronization, thereby avoiding loss of the PCI device due to hot restart.
In this embodiment, it can be seen that, the GPIO signal interface of the ARM processor is physically connected to the Reset signal interface of the PCI slot with the bandwidth x16, the PCI slot with the bandwidth x16 can be split into PCI slots with other bandwidths, a GPIO state value required for the hot restart operation is executed by the PCI slot with each bandwidth, an output state value of each GPIO signal interface is set, each GPIO signal interface is controlled to output a GPIO signal corresponding to the output state value, and the preset time is delayed, so that the hot restart of PCI devices with different bandwidths can be achieved.
On the basis of the above-described embodiment:
as an optional embodiment, after delaying the preset time, the method for the PCI device to warm-restart further includes:
and controlling each GPIO signal interface to output the GPIO signal according to the high state value.
Specifically, considering that the PCI slot with the x16 bandwidth may be split into PCI slots with multiple bandwidths, and the GPIO state values required for the hot reboot operation performed by the PCI slots with different bandwidths are different, when the PCI slot with the x16 bandwidth is split into the PCI slots with multiple different bandwidths, such as when the PCI slot is split into x8x4x4, the steps S102 to S103 need to be executed multiple times, so as to control the hot reboot of the PCI devices in the PCI slot with the x8 bandwidth and the hot reboot of the PCI devices in the PCI slot with the x4 bandwidth, respectively.
For example, the output state values of the 4 GPIO signal interfaces may be set according to the GPIO state value required for the hot restart of the PCI slot with the bandwidth of x8, so that the 4 GPIO interfaces output corresponding GPIO signals and delay the preset time, thereby completing the hot restart of the PCI device with the bandwidth of x 8. In order to meet the subsequent hot restart function of the PCI slot with the bandwidth of x4, after the preset time is delayed, each GPIO signal interface is controlled to output GPIO signals according to high state values, then the output state values of 4 GPIO signal interfaces are set according to the GPIO state values required by the hot restart of the PCI slot with the bandwidth of x4, the 4 GPIO interfaces are enabled to output corresponding GPIO signals and delay the preset time, and the hot restart of the PCI equipment with the bandwidth of x4 is completed.
It can be understood that, because GPIO state values required for the hot reboot of the PCI slots with different bandwidths are different, when the PCI device with the x4 bandwidth is rebooted, the normal operation of the PCI device with the x8 bandwidth is not affected, and similarly, when the PCI device with the x8 bandwidth is rebooted, the PCI device with the x4 bandwidth is not affected.
To sum up, in this application, BIOS confirms that the PCI slot is from which processor and whether the conditions such as split condition exist confirms the GPIO state value table that this PCI slot used through confirming that different bandwidth PCI slots come from before PCI enumeration, BIOS code draws down and delays for 100ms through simultaneously 4 GPIO signals according to the state value table in order to realize the hot restart function of different bandwidth PCI slot equipment, the function that PCI equipment still can normally be used after the hot restart of ARM server has been guaranteed, effective assurance has been started to ARM server deployment in batches and application, accord with ARM server technology future development trend.
