   1 09:10 < j`ey> Glanzmann: `git rev-list 6f59bc24287..smc/work` that might work, not sure how it deals with merges. git rebase is the better way. but if you do that youre on your own!
   2 09:19 < _jannau_> Glanzmann: git rebase --onto 5.17-rc3 6f59bc24287
   3 09:23 < j`ey> if you add -p it can also preserve the merges
   4
   5 19:13 < j`ey> but there's also CONFIG_OF_DMA_DEFAULT_COHERENT, which makes of_dma_is_coherent always return true

   7 21:02 < jannau> mps: you need https://lore.kernel.org/u-boot/20220208210215.8612-1-j@jannau.net/ for extlinux
   8
   9 ARCH: 23:29 < ah-[m]> yep, exactly. I had to grub-mkconfig -o /boot/grub/grub.cfg, and move my Image.gz to /boot, otherwise it was just what was on the wiki page

  12 19:02 < jannau> I think based on this branch https://github.com/AsahiLinux/linux/tree/cpufreq/v1

  14 23:41 < kov> Glanzmann, hmm interesting, I'll try upgrading libinput firs then, see if that fixes it
  15 23:42 < kov> it's weird because I remember the trackpad working a while ago
  16 23:45 -!- mtjzh (~mtjzh@2a02:8388:1742:9b80:658f:93d3:ec68:d60e) has joined #asahi
  17 23:46 < kov> yep, just upgrading to testing's libinput makes it work heh thanks Glanzmann!

  19 Chromium 16KB patch: https://tg.st/u/Set-kernal-page-size-to-16K-on-loongson-MIPS-archtec.patch
  20 10:10 < jannau> see the commit message for 64k on ppc64 https://chromium.googlesource.com/chromium/src.git/+/445c099c6486b8e5ff8dafaefcd812a7ea4bdfff%5E%21/
  21 15:26 < tpw_rules> Glanzmann: https://pastebin.com/NzJEQJDW - https://tg.st/u/NzJEQJDW
  22 15:26 < tpw_rules> last i checked the built chromium only worked with the flags --in-process-gpu --no-sandbox --no-zygote but that may have been a kernel config problem

  25 22:39 < jannau> `dtc -I fs -O dts -o - /proc/device-tree` will output the device-tree as seen by linux
  26
  27 19:11 < Glanzmann> axboe: Could you explain how to mark a device as write-through? Does that mean if I issue a sync in Linux that no flush will happen. Because this would be helpful for the m1 notebook owners to improve performance.
  28 19:11 < axboe> I just do: `echo "write through" > /sys/block/nvme0n1/queue/write_cache"` for now...
  29 19:11 < axboe> Glanzmann: ^^
  30 19:12 < axboe> Glanzmann: and yes, that's what it means
  31 19:12 < Glanzmann> axboe: Thanks.
  32 19:12 < axboe> Glanzmann: it'll bump your test case from 56 iops to 14k or something like that :)
  33 19:12 < axboe> alternatively, some sort of time based hack might make sense
  34 19:13 < axboe> "only issue flush if X seconds has passed since last issue"
  35 19:13 < axboe> kinda nasty, but safer
  36
  37 15:50 < mps> axboe: Glanzmann: `libinput Disable While Typing Enabled (268):    1` is set in my case and it works fine
  38 15:51 < mps> though I built latest beta of libinput and rebuilt xf86-input-libinput with it
  39 15:52 < mps> i.e. libinput-1.19.901
  40 15:52 < axboe> mps: promising
  41 15:53 < mps> but still didn't got it to detect thumb
