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

22:39 < jannau> `dtc -I fs -O dts -o - /proc/device-tree` will output the device-tree as seen by linux
21:56 < povik> that mode of playing in parallel through the speakers and jack has a defect
21:57 < povik> there's noise mixed-in then, at a period
21:57 < povik> don't know how that happens yet
+When disabling the speakers, run rm -rf ~/.config/pulse/ and reboot otherwise the jack will be in the future off or 100% (which is too loud).

If you see this in Xorg.0.log, it means that simpledrm has not initialized.

+Howto convert from the old bootchain to the m1n1 chainloaded bootchain:
+
+(air) [~] parted /dev/nvme0n1 print
+Model: APPLE SSD AP0512Q (nvme)
+Disk /dev/nvme0n1: 500GB
+Sector size (logical/physical): 4096B/4096B
+Partition Table: gpt
+Disk Flags:
+
+Number Start End Size File system Name Flags
+ 1 24.6kB 524MB 524MB iBootSystemContainer
+ 2 524MB 400GB 399GB Container
+ 3 400GB 402GB 2501MB
+ 4 402GB 403GB 513MB fat32 boot, esp
+ 5 403GB 495GB 91.8GB ext4 primary
+ 6 495GB 500GB 5369MB RecoveryOSContainer
+
+I deleted partition 4 and 3, run the asahi installer again.
+
+Than I booted debian from the live stick and mounted the root filesystem and the efi file system:
+
+mount /dev/nvme0n1p5 /mnt
+mount /dev/nvme0n1p4 /mnt/boot/efi
+
+Than I bindmounted the rest of it:
+
+mount -t sysfs none /mnt/sys
+mount -t efivarfs none /mnt/sys/firmware/efi/efivars
+mount -t proc none /mnt/proc
+mount -o bind /dev /mnt/dev
+mount -o bind /dev/pts /mnt/dev/pts
+
+Than I changerooted into it:
+
+cd /mnt
+chroot . bin/bash
+
+blkid
+# Than I updated /etc/fstab with the new id of the efi partition
+
+curl -sLo /boot/efi/m1n1/boot.bin tg.st/u/u-boot.bin
+
+grub-install --removable /boot/efi
+
+exit, umounted everything and rebooted.

+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
