Subject: enabling aspm on ati radeon
Date: Wed, 15 May 2013 22:25:37 -0400	[thread overview]
Message-ID: <519443A1.8050905@ubuntu.com> (raw)

I thought that booting with the pcie_aspm=force option should make
sure this was enabled, but passing this to a 3.8.0 kernel, lspci still
shows:

LnkCap:	Port #0, Speed 5GT/s, Width x16, ASPM L0s L1, Latency L0
<64ns, L1 <1us ClockPM- Surprise- LLActRep- BwNot-
LnkCtl:	ASPM Disabled; RCB 64 bytes Disabled- Retrain- CommClk+
ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-

What could be disabling ASPM?  dmesg confirms: [    0.000000] PCIe
ASPM is forcibly enabled
