Embodiment Construction
[0016] In order to make the purpose, content, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.
[0017] figure 1 Shown is the software and hardware connection diagram of the domestic server platform to simulate the keyboard soft shutdown button to control the soft shutdown, such as figure 1 As shown in the figure, a connection is established between the chassis management (BMC) inside the domestic server platform and the domestic server host (CPU) through USB; the application software in the chassis management (BMC) transmits data to the chassis management (BMC) kernel through the proc interface. The remote management computer establishes a connection with the domestic server platform chassis management (BMC) through the network.
[0018] like figure 1 As shown, a method for simulating a soft-shutdown button on a keyboard to...

The invention relates to a method for simulating a keyboard soft shutdown button to realize remote soft shutdown, which includes: modifying the chassis management kernel code, exporting the proc interface of the iUSB virtual keyboard device in the chassis management kernel; receiving the soft shutdown sent by the remote management computer command; analyze the received soft shutdown command, simulate it into a shutdown key code, and form a data format supported by the chassis management kernel, and transmit it to the chassis management kernel through the proc interface; the chassis management kernel obtains the device of the chassis management iUSB virtual keyboard device information; the chassis management kernel converts the soft shutdown command data into data in the USB Report format supported by the domestic server host according to the device information obtained in the steps; the chassis management kernel sends the converted data in the USB Report format to the domestic server host through USB; After the domestic server host receives the data in USB Report format, the domestic operating system executes the soft shutdown command operation.
Description
technical field [0001] The invention relates to a computer on-off control technology, in particular to a method for simulating a keyboard soft-off key to realize remote soft-off. Background technique [0002] In domestic server platforms, the chassis management method is usually used to realize server remote management functions including remote power control and KVM overIP. In terms of server remote power control, since the domestic platform does not support ACPI, the existing methods are to directly control the CPLD to cut off through the chassis management. The method of the server motherboard power supply meets the requirements of remote shutdown. This method belongs to the hard shutdown method of forced power off, and it is easy to cause the domestic operating system to crash due to errors in the system data saving during the power control process of the server. Therefore, it is necessary in the server platform. An operation method of remote soft shutdown is realized, w...
