AI Technical Summary

Technical Problem

In servers, the increase in the number of PCIe devices and the increased demand for MMIO resources may lead to the exhaustion of MMIO resources, resulting in system startup or device initialization failures, or even system crashes. Existing technologies lack intelligent recovery and reallocation mechanisms.

Method used

By establishing a bus link during system startup to identify hardware devices, obtain configuration information, generate a resource reallocation table, and trigger a system restart, resource allocation is optimized based on preset hardware priorities and resource adjustment strategies to avoid downtime caused by insufficient resources.

Benefits of technology

It improves the system's processing capacity under resource shortage conditions, avoids downtime issues, enhances the rationality and efficiency of resource utilization, and strengthens the stability and flexibility of system startup.

Abstract

The invention relates to the technical field of computer system resource management, in particular to a resource allocation method and computer device.The method comprises the steps that in response to system starting, a bus link is established, and connected hardware devices are recognized through a bus; acquiring configuration information of the hardware equipment, wherein the configuration information at least comprises a resource request value; according to the resource request value, allocating corresponding system resources to the identified hardware equipment; when it is detected that the available resources of the system are insufficient, allocation is stopped, a resource reallocation table is generated according to a preset hardware priority and a resource adjustment strategy, the resource reallocation table is stored to a preset position, and system restart is triggered; and in response to system restart and the same hardware equipment, allocating system resources according to the resource reallocation table. Through the method, the resource allocation success rate and the system stability can be improved.
