09:06 jnettlet[m]> Ke: I don't think there is anything there that is USB specific. Some PCIe fixes, and then SFP / networking
12:54 jnettlet[m]> any QT5 users here? I am wondering what a good performance test for the GPU is.
17:29 jnettlet[m]> for those interested. I know I was talking topi about it a bit ago. Currently our full HB2 carriers suspend to ram power draw is 38mA at 12V so about 468mW
17:47 jnettlet[m]> but for those interested in real world etnaviv vs galcore performance. Using the Qt5_CinematicExperience as a benchmark, the etnaviv driver struggles with 30fps at 720p, the binary driver is able to do a solid 60fps...this is in the main screen with everything enabled. So still quite a bit of ground to make up.
17:52 Ke> I don't think many people want to use the open source drivers for gaming
17:52 Ke> but who knows
17:52 Ke> I would be more interested to know, whether you can render 4K video
17:53 Ke> or 1080p video
17:57 jnettlet[m]> On the MX6 it can do 1080p not 4k
17:58 Ke> it's possibly not just about the encoder but also about rescale ability
17:58 jnettlet[m]> I haven't tested the MX8m yet. It can do 4K video fine. The GPU is much faster.... Still same bugs I have had to adapt and patch.
17:59 Ke> do you mean that actually rendering 4K to a 4K display was possible due to strict limitations of the spec or just too slow
17:59 Ke> s/possible/impossible/
18:00 jnettlet[m]> The MX6 doesn't have a clock fast enough to display 4k even 4k30
18:00 Ke> display encoder?
18:00 Ke> or gpu
18:02 jnettlet[m]> Yes... Basically everything. In theory the GPU can handle 4k sized textures... But the memory controller would be a huge bottleneck. The VPU decoder can't handle 4k video. Even with the new clock changes that allow it to run at 396Mhz
