04:13 <wens> the rockchip SPI driver caps the transfer rate at 50 MHz. Is this a hardware limit (as in the controller can only go so fast without logic issues) or a clock limit (which looks like can be worked on)?

04:13 <wens> btw, it also gives out one warning per transfer if the rate is above 50 MHz, which is a bit annoying

07:22 <hanetzer> https://bpaste.net/show/aaf65dae8d85 progress is being made guys :)

09:01 <sphalerite> does rk3399 support armv7 instructions, or is it armv8-only?

09:01 <phh> it supports armv7

09:16 <sphalerite> cool, thanks!

09:23 <maz> sphalerite: being pedantic, it supports AArch32 ARMv8, which is isn't strictly ARMv7.

09:24 <maz> sphalerite: ARMv8 is not 64bit only.

09:24 <sphalerite> right

09:24 <sphalerite> what are the differences?

09:26 <maz> sphalerite: a number of deprecated instructions, additional features in privileged ELs. each revision of the 8 architecture adds more.

09:26 <maz> v8*

11:07 <topi`> anyone running a mainline kernel on Rockpro64? I have the 4.4.132 precompiled kernel built by ayufan, but it seems to deadlock sometimes

11:07 <topi`> especially if running Firefox or Chromium on any javascript-heavy site

11:07 <topi`> I think I should give the mainline kernel a try

12:48 <sphalerite> I'm having the eMMC hang issue on my rk3288 c201 chromebook. Is there a known fix?
