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
6
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
10
11 https://lore.kernel.org/linux-arm-kernel/20211011165707.138157-1-marcan@marcan.st/
12 19:02 < jannau> I think based on this branch https://github.com/AsahiLinux/linux/tree/cpufreq/v1
13
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!
18
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
23 Upstream BUG: https://bugs.webkit.org/show_bug.cgi?id=236564
24 16:21 < tpw_rules> https://bugs.chromium.org/p/chromium/issues/detail?id=1301788
25
26 22:39 < jannau> `dtc -I fs -O dts -o - /proc/device-tree` will output the device-tree as seen by linux
27
28 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.
29 19:11 < axboe> I just do: `echo "write through" > /sys/block/nvme0n1/queue/write_cache"` for now...
30 19:11 < axboe> Glanzmann: ^^
31 19:12 < axboe> Glanzmann: and yes, that's what it means
32 19:12 < Glanzmann> axboe: Thanks.
33 19:12 < axboe> Glanzmann: it'll bump your test case from 56 iops to 14k or something like that :)
34 19:12 < axboe> alternatively, some sort of time based hack might make sense
35 19:13 < axboe> "only issue flush if X seconds has passed since last issue"
36 19:13 < axboe> kinda nasty, but safer
37
38 15:50 < mps> axboe: Glanzmann: `libinput Disable While Typing Enabled (268): 1` is set in my case and it works fine
39 15:51 < mps> though I built latest beta of libinput and rebuilt xf86-input-libinput with it
40 15:52 < mps> i.e. libinput-1.19.901
41 15:52 < axboe> mps: promising
42 15:53 < mps> but still didn't got it to detect thumb
43 16:07 < mps> Glanzmann: `libinput quirks list /dev/input/event1` will show you features of input device
44 16:09 < mps> and `libinput quirks list /dev/input/event1` will show quirks from libinput database
45
46 From mps:
47 #!/bin/sh
48 echo 2 > /sys/module/hid_apple/parameters/fnmode
49 echo 1 > /sys/module/hid_apple/parameters/swap_fn_leftctrl
50 echo 1 > /sys/module/hid_apple/parameters/swap_opt_cmd
51
52 19:19 < Glanzmann> sven: Do you know why axboe set the admin queue to 2 instead of 8?
53 19:19 < sven> yes
54 19:19 < sven> almost all commands go through the io queue, no need to waste that space for the admin queue
55
56 # j`ey on deleting efi and Linux partitions from the gui in macos
57 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
58 10:53 < j`ey> Glanzmann: for your notes: < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
59 21:07 < tpw_rules> you can delete a non-apfs partition with: diskutil eraseVolume free n disk0sX
60
61 08:54 < mixi> Glanzmann: the command you're looking for should be "dtc -I dtb -O dts /sys/firmware/fdt"
62 08:57 < jannau> Glanzmann: dtc -I fs -O dts -o - /proc/device-tree
63
64 # j`ey on hack to hookup lid close/open
65 23:19 < j`ey> apple_smc_event_received in drivers/platform/apple/smc_core.c is a good place to start looking
66
67 # kettenis on the same issue using existing infrastructure
68 23:20 < kettenis> so the lid is hooked up to gP01
69 23:24 < kettenis> looks like you could try hooking that up using gpio-keys-polled
70 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?
71 23:29 < kettenis> look at arch/arm/boot/dts/imx6q-novena.dts
72
73 # How to subscribe to smc events
74 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);
75 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
76
77 # More background
78 23:54 < kettenis> if the interrupts are hooked up correctly for thise SMC gpios, gpio-keys instead of gpio-keys-polled should work
79 23:54 < j`ey> no irq_chip in the current driver
80
81 17:34 <marcan> the image as built will have a real grub config with static UUIDs
82 17:35 <marcan> well, a systemd early unit but yes

136 cloud-initramfs-growroot
137 16:00 < Glanzmann> So applying a new uuid to the rootfs needs to be done in the initrd.

139
140 07:54 < VinDuv> So I’ve been looking at how macOS installation from USB works on M1 Macs and I think it might be interesting for the Asashi installer. The way it works is that there’s a hidden plist file on the USB drive that references a macOS
141 application on the drive; if this file is present, the USB drive will show up in the power-button-held boot menu, and when selected, it will run the application. It doesn’t seem to care about file signature
142 07:54 < VinDuv> (it works even if the app is just a shell script) and it looks like it’s in 1TR mode.
143 07:56 < VinDuv> So the installation workflow from 1TR could be “plug in a USB stick, hold the power button, select Install Asahi” instead of having to manually open the terminal and run curl | sh. The installer doesn’t even need to be graphical since
144 it’s possible for the launched shell script to start the recovery environment’s Terminal and giving it an arbitrary command to run.
145 07:59 < VinDuv> This is also not limited to external USB drives; it also works if the files are in an APFS volume in internal storage, which I guess might be useful to have a Asahi Recovery boot option in the boot menu or something.

187 19:14 <VinDuv> marcan: I have done a bit more testing with the .IAPhysicalMedia file and it looks like ProductBuildVersion can be any value including blank. ProductVersion seems to be checked against the minimal macOS version supported by the Mac; on my mini the icon shows up in the boot menu only if it’s >= 11.3.
188 19:15 <VinDuv> Maybe it should be set to a higher value for forward compatibility with future Macs that will require 13.0? I’ve tested setting it to 99 and it works.
189
190 21:46 < povik> with pulse, you can get the jack by getting into pacmd
191 21:46 < povik> and running: load-module module-alsa-sink device=hw:0,1
192 21:56 < povik> that mode of playing in parallel through the speakers and jack has a defect
193 21:57 < povik> there's noise mixed-in then, at a period
194 21:57 < povik> don't know how that happens yet
195 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).
196
197
198 If you see this in Xorg.0.log, it means that simpledrm has not initialized.

207 An initialized simpledrm looks like that:

239 I deleted partition 4 and 3, run the asahi installer again.
240
241 Than I booted debian from the live stick and mounted the root filesystem and the efi file system:
242
243 mount /dev/nvme0n1p5 /mnt
244 mount /dev/nvme0n1p4 /mnt/boot/efi
245
246 Than I bindmounted the rest of it:
247
248 mount -t sysfs none /mnt/sys
249 mount -t efivarfs none /mnt/sys/firmware/efi/efivars
250 mount -t proc none /mnt/proc
251 mount -o bind /dev /mnt/dev
252 mount -o bind /dev/pts /mnt/dev/pts
253
254 Than I changerooted into it:
255
256 cd /mnt
257 chroot . bin/bash
258
259 blkid
260 # Than I updated /etc/fstab with the new id of the efi partition
261
262 curl -sLo /boot/efi/m1n1/boot.bin tg.st/u/u-boot.bin
263
264 grub-install --removable /boot/efi
265
266 exit, umounted everything and rebooted.

268 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
269
270 ## BEGIN NOTES ##
271
272 # HOUSEKEEPING
273 # All testing conducted with channels set to 40% in alsamixer,
274 # with no amp gain.
275
276 # Do NOT try to play sound with the speakers set to 100% in alsamixer,
277 # you will fry the cones!
278
279 # DRIVER MAPPINGS/ALSA QUIRKS
280 # The speaker array as set up by the ASoC driver maps like
281 # this on a J314s:
282 # 0: Left Woofer 1
283 # 1: Right Woofer 1
284 # 2: Left Tweeter
285 # 3: Right Tweeter
286 # 4: Left (Sub)Woofer 2
287 # 5: Right (Sub)Woofer 2
288
289 # ALSA sets up the speaker array on the J314s as a 4.0 surround system,
290 # with the RL and RR channels duplicated across the woofers like this:
291 # 2: Front Left
292 # 3: Front Right
293 # 0: Rear Left
294 # 1: Rear Right
295 # 4: Rear Left
296 # 5: Rear Right
297
298 # Obviously this is not correct, but for us it does not matter, since
299 # we can just tell ALSA to route FL and FR to all drivers, presenting
300 # it to the rest of userspace as a stereo device. Surround sources
301 # are downmixed appropriately.
302
303 # SOUND CHECK
304 # Testing reveals that drivers 4 and 5 are likely
305 # only there to help with bass and sub bass. They
306 # are extremely bad at reproducing frequencies above
307 # ~500Hz, and even with the help of the tweeters sound
308 # rough/deep fried in the mids. Drivers 0 and 1 are obviously
309 # intended to be the main woofers in the array.
310
311 # If we weren't intending to mimic whatever macOS does, my ear-only
312 # testing would have me setting up a xover network like this:
313
314 # Freq Range (Hz) | Drivers
315 # 0-300 | 0 1 4 5
316 # 300-6500 | 0 1
317 # 6500-20000 | 2 3
318
319 # Figures based on typical {LP,BP,HP}F rolloff characteristics.
320
321 # Using all 4 woofers below 300Hz moves more air than just using the
322 # (sub)woofers alone. 3-way loudspeakers work like this conventionally.
323
324 # The ttable in the j314s-array pcm device tries to compensate for the lack of
325 # EQ right now by greatly reducing the volume of 4 and 5, and slightly reducing
326 # the volume of 0 and 1 relative to 2 and 3. I have found this gives an acceptably
327 # clear sound without being too bright or losing too much out of the mids. Bass is
328 # nonexistent, though I suspect this is just because we have not applied appropriate
329 # correction to overcome the machine's housing yet. I will not be applying EQ or filtering
330 # in ALSA using plugins even in the interim because
331 # a) it's deprecated
332 # b) it introduces overhead and chews up CPU time
333
334 # FIRs can be applied to a 6 channel slave PCM which would then feed the routing table
335 # PCM configured below with all coefficients set to 1

382 17:02 < kov> Glanzmann, that is already on the 2.34.6 stable release
383 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
384 already in
385 17:04 < kov> it's this one https://gitlab.gnome.org/GNOME/gnome-shell/-/commit/be8a1dcbfc7edf19ef13a63ddf034dba814ee000

387 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

409 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?
410 20:30 < jannau> chainload tell's the 1st stage m1n1 from where to load the second stage
411 20:31 < jannau> chosen.asahi,efi-system-partition is added to the dt mostly to allow u-boot to boot from the correct ESP
412 20:32 < Glanzmann> I see. Thank you for the elaboration.
413 20:32 < jannau> chosen.asahi,efi-system-partition is passed from the 1st stage forward to the second stage
414 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.

416 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

418 23:23 <@jannau> Glanzmann: on the mini vram can fit 5.5 million pixels, would be good for 3440x1600 or 3840x1433 at 32bpp
