[Bug 1398544] Re: Please enable CONFIG_PCIEASPM_DEBUG


Hello, how did you decide? Will you enable CONFIG_PCIEASPM_DEBUG?

You received this bug notification because you are a member of Kernel
Packages, which is subscribed to linux in Ubuntu.


Status in linux package in Ubuntu:
  In Progress

Bug description:
  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.
