Embodiment 1
[0024] figure 1 It is a schematic flowchart of the realization of the display hot-swap processing method provided by Embodiment 1 of the present invention, and the execution body of the method is the display hot-swap processing system / equipment. see figure 1 As shown, the display hot-swapping processing method provided in this embodiment includes the following steps:
[0025] Step S101, if a hot-plug event broadcast by the kernel is received, obtain device information of the current hot-plug device.
[0026] Preferably, in this embodiment, before step S101, it also includes:
[0027] Pre-configuring the display hot-swap rule file, the display hot-swap rule file includes at least one set of matching keys and assignment keys;
[0028] Wherein, the matching key includes the device name, the subsystem to which it belongs, event behavior and graphics driver information; the assignment key includes the specified hot-plug display processing program.
[0029] The event behavior in...
Embodiment 2
[0041] figure 2 It is a schematic flowchart of the realization of the display hot-swapping processing method provided by Embodiment 2 of the present invention, and the execution body of the method is the display hot-swapping system / equipment. see figure 2 As shown, the display hot-swapping processing method provided in this embodiment includes:
[0042] Step S201, if a hot-plug event broadcast by the kernel is received, obtain device information of the current hot-plug device.
[0043] Step S202, traverse the pre-configured display hot-swap rule file according to the device information, and query whether there is a hot-swap display processing program that matches the device information in the display hot-swap rule file; If the hot-plug display processing program matching the above-mentioned device information is used, the process goes to step S203.
[0044] It should be noted that, since the implementation manner of steps S201 to S202 in this embodiment is completely the sa...
Embodiment 3
[0057] image 3 It is a schematic flowchart of the realization of the display hot-swap processing method provided by the third embodiment of the present invention, and the execution body of the method is the display hot-swap system / equipment. see image 3 As shown, the display hot-swapping method provided in this embodiment may include the following steps:
[0058] Step S301, if a hot-plug event broadcast by the kernel is received, obtain device information of the current hot-plug device.
[0059] Step S302, traverse the pre-configured display hot-swap rule file according to the device information, and query whether there is a hot-swap display processing program that matches the device information in the display hot-swap rule file; If the hot-plug display processing program matching the above-mentioned device information is used, the process goes to step S303.
[0060] Step S303, read the EDID of the display, and judge whether the EDID of the display is empty; if the EDID o...
