13:47 <hexdump0815> digetx: these are the changes i had to do to the ucm files on nyan to make pulseaudio happy with it again: https://pastebin.com/raw/Ag6MdE3d

13:48 <hexdump0815> essentially some mixer settings seem to have been gone and the the name changed from i think something like GoogleNyanBig or so to tegra

13:49 <hexdump0815> i think such breaking changes on nyan should not be that much or a problem as the userbase seems to be quite small - but you mentioned that it might maybe not be intended this way

13:50 <hexdump0815> building you current grate kernel right now to test if your latest display setup changes are working well - will let you know when i have tested it

17:15 <hexdump0815> digetx: test passed :) ... the display init is running well with the latest grate kernel on the 2g and 4g nyan - so your reworked changes seem to work well too

17:16 <hexdump0815> while getting the grate kernel working well here with my setup i noticed a few things:

17:23 <hexdump0815> 1. CONFIG_TEGRA20_APB_DMA=y was required to get SPI_TEGRA20_SLINK=y and CONFIG_SPI_TEGRA114=y which are required for the keyboard to work (my kernel config is defconfig based and thus this missing one was blocking the spi options in my case)

17:25 <hexdump0815> 2. there are a few patches, which still seem to be needed for the nyan

17:25 <hexdump0815> 2.1. https://github.com/hexdump0815/linux-mainline-and-mali-generic-stable-kernel/blob/master/misc.cbt/patches/xusb-usb-role-switch.patch - without this the usb ports are not working

17:27 <hexdump0815> 2.2. https://github.com/hexdump0815/linux-mainline-and-mali-generic-stable-kernel/blob/master/misc.cbt/patches/cec-and-dfll-clock.patch - without this one cpu freq scaling was not working reliable, not sure about cec part (don't have a tv to test)

17:28 <hexdump0815> 2.3. https://github.com/hexdump0815/linux-mainline-and-mali-generic-stable-kernel/blob/master/misc.cbt/patches/nyan-thermal-workaround.patch - i got this one from you to keep the temperature in control, without it the nyan would overheat and do an emergency shutdown at some point under constant load

17:29 <hexdump0815> do you see any chance to get those upstreamed somehow as well?

18:01 <hexdump0815> 2.4. i checked the extra kernel config options i'm using for the nyan and checked which of them are not yet in tegra_defconfig - maybe they should be added/considered - https://pastebin.com/raw/ZbmsLTny

18:02 <hexdump0815> i found them over time by research and trial and error to get all hardware on the nyan working as good as possible - maybe you have an idea which of them can go into tegra_defconfig for sure

18:47 <digetx> hexdump0815: it should be possible to get those patches scheduled for 5.17, I'll take care of them

18:48 <digetx> I'll check how to restore the audio controls, thank you

19:03 <hexdump0815> digetx: cool - thanks a lot

21:21 <jenneron[m]> digetx: hi, can you correct tabs here (in v4?) and probably remove sdmmc1 pinmux as it is not used?

21:21 <jenneron[m]> https://github.com/grate-driver/linux/blob/master/arch/arm/boot/dts/tegra114-asus-tf701t.dts#L811-L812

21:22 <jenneron[m]> or should i send a PR

21:23 <digetx> will be better to have a PR

21:25 <jenneron[m]> what about sound and brightness control? as i mentioned before it doesn't work yet

21:26 <jenneron[m]> sound appears in alsamixer, but not tested due to missing ucms and backlight can just enable/disable, not adjust brightness

21:42 <digetx> there is no real problem with patching DT later on until ucms will be upstreamed, brightness can be fixed later on, shouldn't be a problem
