I might be imagining it resynchronizing

Random thought: maybe the t6k broken mesa side on macOS was due to too-small preemption buffers?
<lina>
It makes sense that those would have to be larger for more cores
<lina>
And that would cause breakage only when preemption happens, so "flakiness"

were the premption buffers allocated from userspace?

Well... I have it lining up, but I had to do weird, unexplainable changes to a few of the padding sizes
karolherbst has quit [Ping timeout: 480 seconds]
<phire>
like, I made them smaller. Why would the (allegedly) newer hardware device have almost the same initdata layout but with slightly less padding in a few places?

On macOS, yes (on Linux I do it in the kernel right now)
<lina>
phire: Maybe the firmware versions actually diverge? Like G13X got forked off of G13G before G14G support got added or started to be added?
<lina>
I wonder if it would match better at another version...

better?
<bluetail>
Yea. Now I can see you again in all your beauty :). By the way, do you plan on collecting funds, getting support in some way? Your work is so amazing!
karolherbst has quit [Ping timeout: 480 seconds]
<phire>
Oh right... It would be a mistake to assume we are getting the same AGX firmware version on all chips
<phire>
Is there an easy way I can check agx firmware version from macos without m1n1?
<_jannau_>
phire: ioreg?
<phire>
Hopefully
<phire>
AGXTraceCodeVersion?
<phire>
There is also IOSourceVersion
<phire>
IOSourceVersion is 190.22; AGXTraceCodeVersion is 3.24.4 (on macos 12.6)
<lina>
phire: Wait, you're on 12.6? The supported version is 12.3 right now...
karolherbst has joined #asahi-gpu
<phire>
my non-dev macos install is on 12.6, I also have installs of 12.1 and 12.2 that I can reboot into
<phire>
oh... which macos versions does the m1n1 agx driver implement? I thought it was 12.1 and 13.0 beta 4
<_jannau_>
12.3 as the stub version used by the asahi-installer
<_jannau_>
apple has unfortunately stopped providing a 12.3 installer via softwaretupdate
<phire>
do we need to be archiving those?
<_jannau_>
or we need to extend the asahi-installer to install macos
<phire>
that sounds cursed
<bluetail>
use the asahi-installer to install >just the version that works with asahi-linux<
<bluetail>
yea... I dont think marcan would want that
<ChaosPrincess>
can't you download it as a pkg from apple's cdn and install it that way
<marcan>
I thought softwareupdate always let you grab older versions (if explicitly specified)?
<bluetail>
Hi marcan. I love you. We all love you. You are the best. Uhm. You still mute your mic when entering a password as sudo? I decided to just mute my mic always, until i use it. Also, off-topic. :D
<phire>
*checking*
<marcan>
... that was kind of random
<phire>
Scanning for 12.3 installer
<phire>
Install failed with error: Update not found
<bluetail>
... I'm bored, waiting for a colleague instead of using something more productive. I'm sorry
<marcan>
ugh.
<marcan>
I did not know Apple would drop old macOS versions.
<sven>
huh. that’s quite annoying
<phire>
annoying
<marcan>
I have a copy of InstallAssistant.pkg for 12.3 but I really don't want to become our personal CDN for Asahi firmware support versions :/
<sven>
I hope they just removed the link in some plist and kept the pkg link alive
<phire>
Guess they need to save space on their CDN
<marcan>
yet they keep the IPSWs..
<phire>
so... we just need them to appear on archive.org
<sven>
that’s why I hoped they kept the pkg as well :/
<marcan>
and they keep random Big Sur builds so I guess they just drop older point releases?
<phire>
anyway, I thought the driver in m1n1 was 12.1, lina?
<lina>
No, it's 12.3
<phire>
ok, that would explain the extra padding then
<marcan>
looks like the "m2 special" 12.4 is still available, better grab that... that will cover both firmwares we currently ship.
<lina>
You've been testing on 12.1 or 12.6?
<phire>
All I've done is pulled up the initdata dump I did back on 12.1 and I've been parsing it with m1n1
<lina>
Oh...
<phire>
as O
<phire>
as I'm at xdc and don't have a second computer to run m1n1 from
<lina>
I don't remember how much initdata changed from 12.1 to 12.3, but I think it wasn't zero
<phire>
there was no change between 12.1 and 12.2
<phire>
oh... I just had an evil thought. I can probally run m1n1's proxy client on a phone

alyssa: have you observed any restrictions on number of PPP updates? or does `MAX_PPP_UPDATES` in the gallium driver simply refer to the maximum allocated space for them in the command encoder.
