05:52 <tony_> naobsd: hello, long time no see.

09:08 <rperier> hi, Did someone test RTC_HYM8563 recently ? the drivers hangs when it registers/enables clk xin32k (that's not caused by the driver itself, perhaps a clk bug)

09:32 <stdint> I need to buy a battery to verify

09:34 <rperier> problem is present in 4.7, 4.8, 4.9 and 4.10

09:55 <rperier> it's working in 4.5, so possible regression with 4.6

10:10 <eballetbo> hi, what's missing to enable Rockchip IOMMU on ARM64?

10:16 <phh> eballetbo: you mean in mainline right?

10:16 <eballetbo> yes, yes, in mainline

15:14 <mmind00> eballetbo: I think the two most recent patches in Dave Airlies tree

15:15 <mmind00> (concerning Rockchip drm of course)

15:15 <mmind00> eballetbo: I already managed to get graphical output on Gru (rk3399) once, two weeks ago

15:18 <eballetbo> mmind00: oh, cool, do you have a repo with those changes?

15:20 <mmind00> not really right now, but it's really only the topmost two of https://cgit.freedesktop.org/~airlied/linux/log/drivers/gpu/drm/rockchip?h=drm-next

15:23 <eballetbo> and use the same bindings as chromeos-4.4, right?

15:24 <mmind00> I think so ... I also only used the chromeos gru dts files

18:23 <phh> LongChair: fwiw, the rk3288 board I have here, which does 4k in android, has 1100MB/s RAM. I'll check decoding in linux soon (I need to fix hdmi...)

21:46 <phh> LongChair: decoding with gstreamer isn't smooth either. decoding with null video output of a 5m video, took 3m, so assuming the bottleneck is the RAM, it would need to be able to do that in 2.5 to be smooth. fwiw, i tested with screen at 60Hz, I'm not too sure whether that matters

21:47 <phh> (with rkximagesink, it's too slow)

21:56 <paulk-collins> no sw scaling involved?

21:56 <paulk-collins> that's more than often a bottleneck

21:57 <phh> no, with rkximagesink, the scaling is done with drm API using VOP IP

21:58 <paulk-collins> nice

21:59 <phh> though I think wzyy2 mentioned that VOP is too slow to do 4k => 1080p

21:59 <phh> only rga or vpu is fast enough for that
