Ooops. The script originally attached is broken, here comes a corrected
version...
BTW: My latest results with computer fully idle:
/sys/module/pcie_aspm/parameters/policy: powersave
cur: 6.17W, avg 10: 6.25W, tot. avg: 6.40W, stddev: 0.44W (n=261)
/sys/module/pcie_aspm/parameters/policy: performance
cur: 6.19W, avg 10: 6.25W, tot. avg: 6.41W, stddev: 0.52W (n=267)
So with my kernel and hardware, ASPM seems to have no effect.
Kind regards,
Thiemo
