 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> 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
