+19:13 < j`ey> but there's also CONFIG_OF_DMA_DEFAULT_COHERENT, which makes of_dma_is_coherent always return true
+
+21:02 < jannau> mps: you need https://lore.kernel.org/u-boot/20220208210215.8612-1-j@jannau.net/ for extlinux
+
+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
+
+https://lore.kernel.org/linux-arm-kernel/20211011165707.138157-1-marcan@marcan.st/
+19:02 < jannau> I think based on this branch https://github.com/AsahiLinux/linux/tree/cpufreq/v1
+
+23:41 < kov> Glanzmann, hmm interesting, I'll try upgrading libinput firs then, see if that fixes it
+23:42 < kov> it's weird because I remember the trackpad working a while ago
+23:45 -!- mtjzh (~mtjzh@2a02:8388:1742:9b80:658f:93d3:ec68:d60e) has joined #asahi
+23:46 < kov> yep, just upgrading to testing's libinput makes it work heh thanks Glanzmann!
+
+Chromium 16KB patch: https://tg.st/u/Set-kernal-page-size-to-16K-on-loongson-MIPS-archtec.patch
+10:10 < jannau> see the commit message for 64k on ppc64 https://chromium.googlesource.com/chromium/src.git/+/445c099c6486b8e5ff8dafaefcd812a7ea4bdfff%5E%21/
+15:26 < tpw_rules> Glanzmann: https://pastebin.com/NzJEQJDW - https://tg.st/u/NzJEQJDW
+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
+Upstream BUG: https://bugs.webkit.org/show_bug.cgi?id=236564
+
+22:39 < jannau> `dtc -I fs -O dts -o - /proc/device-tree` will output the device-tree as seen by linux
+
+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.
+19:11 < axboe> I just do: `echo "write through" > /sys/block/nvme0n1/queue/write_cache"` for now...
+19:11 < axboe> Glanzmann: ^^
+19:12 < axboe> Glanzmann: and yes, that's what it means
+19:12 < Glanzmann> axboe: Thanks.
+19:12 < axboe> Glanzmann: it'll bump your test case from 56 iops to 14k or something like that :)
+19:12 < axboe> alternatively, some sort of time based hack might make sense
+19:13 < axboe> "only issue flush if X seconds has passed since last issue"
+19:13 < axboe> kinda nasty, but safer
+
+15:50 < mps> axboe: Glanzmann: `libinput Disable While Typing Enabled (268): 1` is set in my case and it works fine
+15:51 < mps> though I built latest beta of libinput and rebuilt xf86-input-libinput with it
+15:52 < mps> i.e. libinput-1.19.901
+15:52 < axboe> mps: promising
+15:53 < mps> but still didn't got it to detect thumb
+16:07 < mps> Glanzmann: `libinput quirks list /dev/input/event1` will show you features of input device
+16:09 < mps> and `libinput quirks list /dev/input/event1` will show quirks from libinput database
+
+From mps:
+#!/bin/sh
+echo 2 > /sys/module/hid_apple/parameters/fnmode
+echo 1 > /sys/module/hid_apple/parameters/swap_fn_leftctrl
+echo 1 > /sys/module/hid_apple/parameters/swap_opt_cmd
+
+19:19 < Glanzmann> sven: Do you know why axboe set the admin queue to 2 instead of 8?
+19:19 < sven> yes
+19:19 < sven> almost all commands go through the io queue, no need to waste that space for the admin queue
+
+# j`ey on deleting efi and Linux partitions from the gui in macos
+20:46 < j`ey> Glanzmann: I didnt figure it out at the diskutil cli, but I managed to do it from the GUI, I think you have to erase/reformat as APFS before you can delete the volumes
+10:53 < j`ey> Glanzmann: for your notes: < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
+21:07 < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
+
+08:54 < mixi> Glanzmann: the command you're looking for should be "dtc -I dtb -O dts /sys/firmware/fdt"
+08:57 < jannau> Glanzmann: dtc -I fs -O dts -o - /proc/device-tree
+
+# j`ey on hack to hookup lid close/open
+23:19 < j`ey> apple_smc_event_received in drivers/platform/apple/smc_core.c is a good place to start looking
+
+# kettenis on the same issue using existing infrastructure
+23:20 < kettenis> so the lid is hooked up to gP01
+23:24 < kettenis> looks like you could try hooking that up using gpio-keys-polled
+23:27 < Glanzmann> kettenis: So gpio-keys-polled would poll gP01 and send a key event and than I could use my window manager to do something when that key event is received?
+23:29 < kettenis> look at arch/arm/boot/dts/imx6q-novena.dts
+
+# How to subscribe to smc events
+23:45 < j`ey> Glanzmann: if youre still interested in looking: drivers/power/supply/macsmc_power.c apple_smc_register_notifier(power->smc, &power->nb);
+23:46 < j`ey> so this driver gets called, when an SMC notification happens. looks like all registered handlers would be called and its up to the callback to figure out if it needs to do something
+
+# More background
+23:54 < kettenis> if the interrupts are hooked up correctly for thise SMC gpios, gpio-keys instead of gpio-keys-polled should work
+23:54 < j`ey> no irq_chip in the current driver
