CONFIG_PCIEASPM_DEBUG (which is currently disabled for Ubuntu kernels) can be used to enable/disable ASPM settings per PCIE device. CONFIG_PCIEASPM (which is enabled for Ubuntu kernels) allows only to set global ASPM policy. BIOSes on more machines are buggy and lot of times do not configure ASPM for PCIE device property. CONFIG_PCIEASPM_DEBUG option allows users or testers to hotfix potential bugs in BIOS... That config option only add new sysfs files so it should not break anything else in kernel. |
