so pipehandler as part of dwc3 glue makes everything worse, it'll stay inside atcphy
<sven>
i've also apparently managed to break gadget mode somehow again :/
<sven>
either when converting to the glue driver or when cleaning that one up

can anyone run trace_atc.py while connecting the target to something that makes it switch to device mode? my setup seems to first negotiate host and then do the switch to device mode and i'd like to see something that directly goes to device mode
<chaos_princess>
whats your approach?
<chaos_princess>
also, does it have to be a t8013, or a t6000 is also fine?
<sven>
anything is fine
<sven>
i have a somewhat weird setup here. c-to-c cable to another (x86) computer running linux and that seems to first negotiate host and then switch to device. I think my a-to-c cable that I used before broke because it doesn't negotiate anything anymore
<sven>
even under macos
<sven>
before that the approach was macbook air -> c-to-a adapter -> a-to-c cable -> mac mini
<chaos_princess>
yea, i should have an a-to-c somewhere and a x86 pc
<sven>
atcphy is the same for t8103 and t6000 and all the other supported SoCs. i think apple hides any differences inside the tunables anyway
<sven>
the only reason they have a different ADT compatible is that they hardcode the fuse offsets inside the kext iirc
<chaos_princess>
ok, i might be doing sth wrong, do i need a specific port? And does the cable need to be usb-3 compatible?
<sven>
no, both ports short work :/
<sven>
usb 2 only is fine as well
<sven>
3 would be better because i want to see the pipehandler setup as well, but 2 should be fine
<chaos_princess>
"both" - so, i have 3, and one didn't work :P. captured, give me a sec
<jannau>
j`ey: the problem doesn't apply to dcp as dcp limits fb flips, i.e. we have vblank hw, it's just inconvenient to use. if we used the timer we have deal with syncing it to dcp's swaps
<sven>
timed out waiting for ACIOPHY_TOP_PHY_STAT_LN0_UNK0 that’s also not great
<sven>
I don’t see that here
yuka has quit [Remote host closed the connection]
<jannau>
I don't think I see that with the asahi tree
yuka has joined #asahi-dev
<sven>
can you try moving the phy_set_mode calls to after dwc3_host_init?
<sven>
that makes no sense to me but it’s a difference between Asahi tree and that branch
<jannau>
on shutdown uas errors drom the usb ssd

I hate this thing :(

still "timed out waiting for ACIOPHY_TOP_PHY_STAT_LN0_UNK0" but the delay between "hub 3-0:1.0: 1 port detected" and "new SuperSpeed Plus Gen 2x1 USB device" os now only 4.75s
<sven>
hrm, something else is broken then
<jannau>
this was 5d4191594cf6
<jannau>
same behavior with 90e2c56eccad though

m1 max behaves in the same way as m2
<sven>
hmmm… maybe because I‘m using a usb3/dp connected to my usb 3 hdd here
<sven>
I’m traveling for $work for the rest of the week but I’ll compare macOS vs. my branch on the weekend to see what’s going on
<jannau>
yes, no delay or timeout on ACIOPHY_TOP_PHY_STAT_LN0_UNK0 when using an usb3/dp switch
<sven>
ok, weird but at least that explains the difference
<jannau>
approved the m1n1 PR as the weirdness is unlikely to be found there
<jannau>
didn't you want to use usb3/dp mode by for usb3 only anyway as that's what macos does?
<sven>
ohh… yup
<sven>
and I never understood _why_. maybe we do now
<jannau>
the timeout on ACIOPHY_TOP_PHY_STAT_LN0_UNK0 doesn't change to ACIOPHY_TOP_PHY_STAT_LN1_UNK0 based on the plug orientation
<sven>
can reproduce it here as well when directly connecting the device without the usb3/dp inbetween
