    Question: Why would one still use the CPUFreq govenors on a SNB+ Core i7 machine while Intel provides their P-State govenor that supposedly run much more efficient on their CPUs? What is the...

    Michael, could you please compare the power consumption on your Haswell system between 3.15 and 3.16 drm-next especially when idle? On my Haswell Laptop when idle the cpu frequency frequently jumps...

    cpu frequency in 3.16 is way up if idle, backlight keys on my T440p don't work anymore and system won't enter lower package states even if display is completely off. idle drain is now 19 watts from...

    Hopefully they'll finally do something about the package state issue on Haswell and the resulting high power consumption when idle.

    Nice to see there is still some efford to make the CPU more power efficient. But what about the Package state issues? My Haswell i7 w/o discrete gpu still won't enter PC7 when idle resulting in...

    Got a Lenovo t440p Laptop with a Haswell i7-4600M and the System comsumes twice as much power (16 Watts using Intel P-State driver) during idle state than my old T420 with a I7-2620M both without...

    confirmed, i915_enable_rc6=1 reduces power drain about 30%.
    unfortunately i915_enable_rc6=1 causes the gpu to hang pretty often and to lock up the system entirely as soon as multiple OpenGL or...

    very nice :). I'm keen to see some mobile i5/i7 benchmarks - especially how the IGP performs on the mobile chips. But from what I see it looks my next mandatory purchase will be a SNB laptop :)

    well this is some good news. I'm keen to see know how the mobile SB GPU does. Btw. what about vaapi video decoding? does this actually work? what about some initial benchmarks on that?

    you're probably right however the situation is different with an 4250 IGP :( strange thing is that the blob performance on this IGP is way worse than r600g. :confused:

    finally some real progress on optimizatzions. absolutely amazing work! any ETA for r600g? with r600 classic mesa still seems a lot faster than r600g though.

    patent issues?

    this is weird. I thought OpenGL 3 is widely protected by various patents yet many GL3 functions are being implemented in mesa. So what's the story here? I'm not much of a legal guy so can someone...
