Abstract
A PCIe device error handling system includes a BIOS subsystem coupled to a PCIe device and a BMC device. The BIOS subsystem identifies an error in the PCIe device and, in response, begins an SMM that suspends the performance of at least one workload in an operating system, and generates and transmits a PCIe device error information collection instruction associated with the PCIe device to the BMC device. Subsequent to transmitting the PCIe device error information collection instruction, the BIOS subsystem ends the SMM such that the performance of at least one workload is resumed in the operating system. In response to receiving the PCIe device error information collection instruction from the BIOS subsystem, the BMC device retrieves PCIe device error information from the PCIe device while the operating system performs the at least one workload, and stores the PCIe device error information.
