+12:41 < chadmed> https://gist.github.com/chadmed/2c772c8fdac8280cb17846388203a213 <- some notes on the speaker system in the j314s, and an asound.conf that makes them sound... okay-ish for now
+
+## BEGIN NOTES ##
+
+# HOUSEKEEPING
+# All testing conducted with channels set to 40% in alsamixer,
+# with no amp gain.
+
+# Do NOT try to play sound with the speakers set to 100% in alsamixer,
+# you will fry the cones!
+
+# DRIVER MAPPINGS/ALSA QUIRKS
+# The speaker array as set up by the ASoC driver maps like
+# this on a J314s:
+# 0: Left Woofer 1
+# 1: Right Woofer 1
+# 2: Left Tweeter
+# 3: Right Tweeter
+# 4: Left (Sub)Woofer 2
+# 5: Right (Sub)Woofer 2
+
+# ALSA sets up the speaker array on the J314s as a 4.0 surround system,
+# with the RL and RR channels duplicated across the woofers like this:
+# 2: Front Left
+# 3: Front Right
+# 0: Rear Left
+# 1: Rear Right
+# 4: Rear Left
+# 5: Rear Right
+
+# Obviously this is not correct, but for us it does not matter, since
+# we can just tell ALSA to route FL and FR to all drivers, presenting
+# it to the rest of userspace as a stereo device. Surround sources
+# are downmixed appropriately.
+
+# SOUND CHECK
+# Testing reveals that drivers 4 and 5 are likely
+# only there to help with bass and sub bass. They
+# are extremely bad at reproducing frequencies above
+# ~500Hz, and even with the help of the tweeters sound
+# rough/deep fried in the mids. Drivers 0 and 1 are obviously
+# intended to be the main woofers in the array.
+
+# If we weren't intending to mimic whatever macOS does, my ear-only
+# testing would have me setting up a xover network like this:
+
+# Freq Range (Hz) | Drivers
+# 0-300 | 0 1 4 5
+# 300-6500 | 0 1
+# 6500-20000 | 2 3
+
+# Figures based on typical {LP,BP,HP}F rolloff characteristics.
+
+# Using all 4 woofers below 300Hz moves more air than just using the
+# (sub)woofers alone. 3-way loudspeakers work like this conventionally.
+
+# The ttable in the j314s-array pcm device tries to compensate for the lack of
+# EQ right now by greatly reducing the volume of 4 and 5, and slightly reducing
+# the volume of 0 and 1 relative to 2 and 3. I have found this gives an acceptably
+# clear sound without being too bright or losing too much out of the mids. Bass is
+# nonexistent, though I suspect this is just because we have not applied appropriate
+# correction to overcome the machine's housing yet. I will not be applying EQ or filtering
+# in ALSA using plugins even in the interim because
+# a) it's deprecated
+# b) it introduces overhead and chews up CPU time
+
+# FIRs can be applied to a 6 channel slave PCM which would then feed the routing table
+# PCM configured below with all coefficients set to 1
+
+## END NOTES ##
+
+# Create a six channel slave for the audio array
+pcm_slave.outputs {
+ pcm "hw:0,0"
+ channels 6
+}
+
+
+# We need to map L and R to the correct drivers. We can use
+# the coefficients in ttable to roughly tune the sound profile.

+17:02 < kov> Glanzmann, https://bugs.webkit.org/show_bug.cgi?id=236564
+17:02 < kov> Glanzmann, that is already on the 2.34.6 stable release
+17:03 < kov> the gnome one was unrelated and is from a bunch of months ago, I have not seen any crashes in my testing with debian's gnome so I assume the fix is
+ already in
+17:04 < kov> it's this one https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/be8a1dcbfc7edf19ef13a63ddf034dba814ee000
+
+17:49 < j`ey> marcan: I learnt a new git command just now: git range-diff asahi/asahi-soc/prev..asahi asahi/asahi-soc/next..asahi/asahi good way to compare the
+ new/old branches even after a rebase
+17:49 < j`ey> (where 'asahi' is my local not-yet-updated branch)
+
+21:44 < kov> Glanzmann, trying to use the debian installer from your artefacts and getting a blank screen after the boot, any thoughts? (the consoles on tty2 etc come up)
+21:55 < kov> Glanzmann, hrm adding vga=normal fb=false to the kernel cmdline made it work
+
+07:19 < chadmed> Glanzmann: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2210
+07:47 < chadmed> pushed some changes to asahi-audio, should sound better than it did before now. FIRs are also installed to the directory i proposed in the feature request
+
+15:49 < j`ey> https://github.com/AsahiLinux/asahi-installer/blob/main/src/osinstall.py#L141
+15:49 < j`ey> cat m1n1.bin <(echo 'chainload=$ESP_UUID;$BOOT_OBJ_PATH') > blah.bin
+
+16:43 < povik> marcan: two fixes on top of 'asahi' that should make it into the release: https://github.com/povik/linux/commits/asahi-fixes
+
+# boot into 1tr
+diskutil list
+diskutil info <identifier of esp>
+curl -sLo tg.st/u/m1n1-rust.bin
+cat m1n1-rust.bin <(echo 'chainload=<ESP Partition UUID>;m1n1/boot.bin') <(echo 'chosen.asahi,efi-system-partition=<ESP Parition UUID>') > object.bin
+kmutil configure-boot -c object.bin --raw --entry-point 2048 --lowest-virtual-address 0 -v /Volumes/Linux
+
+20:29 < Glanzmann> One question though what is difference between chosen.asahi,efi-system-partition=EFI-PARTITION-PARTUUID and chainload=EFI-PARTITION-PARTUUID;m1n1/boot.bin?
+20:30 < jannau> chainload tell's the 1st stage m1n1 from where to load the second stage
+20:31 < jannau> chosen.asahi,efi-system-partition is added to the dt mostly to allow u-boot to boot from the correct ESP
+20:32 < Glanzmann> I see. Thank you for the elaboration.
+20:32 < jannau> chosen.asahi,efi-system-partition is passed from the 1st stage forward to the second stage
+20:33 < Glanzmann> I see, so the first stage informs the second stage about the uuid of the esp partition which is than passed using dt to u-boot which can than select the right esp to select the efi binary.
+
+17:25 < Jamie[m]1> I had a dumb idea and had to implement it: using http range requests and DEFLATE trickery to download Wifi firmware from Apple's CDN with only 18MB of transfer (out of a 13GB ipsw) http://github.com/JJJollyjim/firmware-abomination
+
+23:23 <@jannau> Glanzmann: on the mini vram can fit 5.5 million pixels, would be good for 3440x1600 or 3840x1433 at 32bpp

+16:08 <j`ey> looks like theres some results https://browser.geekbench.com/v5/cpu/13927518

+16:14 <bluetail[m]> jannau: same m1 16 gb, 3000 more in multicore. How? https://browser.geekbench.com/v5/cpu/13856349
+16:18 <bluetail[m]> jannau: does it matter? I mean, it looks like we do have geekbench on arm linux...
+16:19 <bluetail[m]> https://www.geekbench.com/blog/2021/03/geekbench-54/
+16:24 <psydroid[m]1> https://browser.geekbench.com/v5/cpu/12429267
+16:25 <jannau> the multicore test doesn't scale well, here are results from a m1 ultra: https://browser.geekbench.com/v5/cpu/13932507
+16:31 <jannau> Chainfire: it's geekbench issue. kernel compiles are on the m1 ultra twice as fast as on the m1 max

+15:58 < kov> Glanzmann, jannau out of curiosity I ran geekbench on my Fedora VM under MacOS (M1 Max - 8 vcpus) https://browser.geekbench.com/v5/cpu/13951703

+14:28 < j`ey> mps: what kinda 'swipes'?
+14:28 -!- bisko (~bisko@0002be12.user.oftc.net) has quit: Ping timeout: 480 seconds
+14:28 < mps> left and right, i.e, next and previous url in firefox
+14:28 < j`ey> ah cool
+14:29 < mps> this is enough for me (for now at least)
+14:30 -!- bisko (~bisko@0002be12.user.oftc.net) has joined #asahi
+14:30 < mps> there is also https://github.com/BlueDragonX/dispad which disables touchpad while typing
+14:32 < mps> but I have to find some time to learn better about all this touchpad options

+07:53 < VinDuv> Glanzmann: I’ll be a bit busy until next week but if you want to play with my patch, it’s here: https://github.com/AsahiLinux/m1n1/pull/183
+07:54 < VinDuv> If you apply both patches and boot with display=wait,3840x2160, it should boot in 4k and m1n1 will say “waiting for monitor disconnect” and then wait 10 seconds
+07:59 < VinDuv> btw I’m working on a Python script that detects, from macOS, if a monitor disconnects during wakeup (so it needs m1n1 to wait) as well as its native resolution. If it works well and is integrated into the installer, it could autoconfigure the display= option in m1n1 during installation.

+14:34 < mps> Glanzmann: I use 'export MOZ_USE_XINPUT2=1' in system wide /etc/profile
+14:35 < mps> and checked out (disabled) smooth scroll in firefox
