03:53 <amw> sven: I would like to try booting a asahi-linux + m1n1 with cdc-acm USB cable - can you suggest linux PR / m1n1 PR to start with?

03:54 <amw> sven: As I have no special serial / USB cable I would be happy to just get frame buffer only working

03:55 <amw> sven: I see a variety of branches in the github repositories + various pull requests - thought it would be nice for some guidance on which to start with.

03:55 <amw> At present I am thinking https://github.com/svenpeter42/linux for Linux

03:58 <amw> Perhaps https://github.com/AsahiLinux/m1n1/pull/39 for m1n1

07:35 <sven> amw: yeah, marcan needs to catch up reviewing :P

07:36 <sven> amw: for m1n1 i have this branch https://github.com/svenpeter42/m1n1/tree/usb-dwc3-serial-wip installed which should give you uartproxy over usb + a framebuffer console

07:37 <sven> amw: if you want usb in linux you're essentially on your own for now. you could start with https://github.com/svenpeter42/linux/tree/dart-iommu which will give you iommu support but you'll still need to configure the dwc3 driver and g_serial

07:38 <sven> keep in mind that this is all still WIP and hasn't really been reviewed or tested by anyone else so expect things to break

10:09 <amw> sven: Thanks - I had compiled up the usb-dwc3-serial one - just switching to the wip one (bleeding edge:-)

10:22 <sven> amw: the only difference to wip are those magic PHY init pokes ;)

10:22 <sven> it won't work at all without them

10:22 <sven> let me know if that branch works or if you run into any issues

10:22 <amw> sven: pretty magic then... ok

10:24 <amw> sven: I think I'll take a few attempts to get to that stage. I might need a better linux config, but kind of excited to see anything at all ...

10:24 <sven> oh, i'm already happy when the usb support in m1n1 works

10:24 <sven> no need for any linux config at that point

10:24 <sven> just install m1n1 with kmutil and hope for the best :-)

11:32 <M3zh[m]> sven: the usb-dwc3-serial-wip branch, does it work for mac mini? If yes then what kind of port is it using? I mean there are two usb controllers and two type ports: usb-c and usb-a ...

11:39 <sven> i'm developing on a mac mini and it's using the usb-c ports

11:39 <sven> it emulates a serial device on both usb-c ports

11:43 <M3zh[m]> cool. do I need any special crossover cable like of xhci dbc? or ordinary usb-c is fine?

11:44 <sven> regular should work

11:44 <M3zh[m]> sven: thx!

11:58 <amw> sven: Hmm Can't seem to bless my m1n1-payload.macho

11:59 <amw> Getting Invalid argument: bless2_install_custom_obj() failed: 103

12:00 <sven> are you in 1TR?

12:02 <amw> I believe so - When I tried before it said I had to be in recovery mode

12:02 <sven> strange

12:02 <amw> So I booted to the Terminal in the recovery options on the new partition.

12:03 <amw> Tried it with the plane m1n1.macho -> same result

12:04 <sven> i assume you've just followed https://github.com/AsahiLinux/docs/wiki/Developer-Quickstart ?

12:05 <amw> It seems to be trying as it asks am I sure, updating local machine policy ..., installing boot objects ... and then fails,

12:05 <amw> sven: Yep Developer-Quickstart

12:06 <sven> just to confirm: how did you boot the mac to get into 1TR?

12:10 <amw> Holding down the power key until options window, Then selecting the new boot partition, then selecting terminal (after logging in)

12:10 <sven> hrm, okay. that should work :/

12:12 <amw> Is there a way to tell if I have the right version of kmutil? I heard the early one doesn't work

12:13 <j`ey> amw: what version of macOS are you on?

12:13 <sven> i've just updated to the latest mac os before running kmutil

12:14 <amw> j`ey: 11.2 - I'm in the recovery terminal at the moment

12:14 <amw> I think it wanted to upgrade to 11.2.3 or something - but I held off.

12:21 <sven> maybe to try update and see if that fixes anything?

12:22 <amw> Yeah. I tried to look through the "Installer Log" but it's hung now after I hit the save button??

12:34 <amw> When I plugged in my USB Type-C to Type-A cable I get my Linux laptop trying to bind cdc_ncm cdc_wdm cdc_mbim

12:34 <amw> Any idea if they are useful ?

12:40 <sven> can you show the dmesg output?

12:40 <sven> but cdc sounds like a good start :)

12:42 <amw> sven: How would I do that over chat? It's multiple lines

12:42 <sven> http://pastie.org

12:43 <amw> sven: Like this http://pastie.org/p/76BWB0tbbhL2Q2dMKwZv8w ?

12:45 <sven> oh, you haven't installed m1n1 yet?

12:45 <amw> sven: Note: I haven't gotten kmutil to complete yet - just rebooting after update now

12:46 <amw> That dmesg was from recovery mode

12:46 <sven> heh, k. i thought you got some message about cdc_ncm,etc. while running m1n1 :)

12:47 <amw> I guess we have WiFi in recovery mode so those others are not any better.

12:49 <amw> It's rather slow booting after the upgrade... - I think actually I should be upgrading the Linux Volume not the normal MacOS one...

12:49 <amw> Looks like I'll be doing that another day...

13:03 <amw> Sigh still rebooting from the upgrade...

13:17 <amw> sven: Hmm it failed to boot my Linux partition, I fell back to recovery, then tried the kmutil and now fails with: Boot policy error: Error creating linked manifest: code BOOTPOLICY_ERROR_AP_BOOT_MODE

13:17 <amw> I think I will have to reinstall the Linux partition - tomorrow....

13:18 <sven> huh, weird

13:18 <sven> BOOTPOLICY_ERROR_AP_BOOT_MODE sounds like you're maybe not in 1TR?

13:18 <sven> but no idea

14:42 <sven> ugh, so usb host mode definitely needs two darts :/

14:43 <sven> but other than that it seems to be enough to initialize this TPS6598x variant and use a slight different phy bringup sequence

15:20 <kettenis2> is there a separate dart for device mode and host mode?

15:21 <sven> i think it's worse

15:21 <sven> there's one dart for the "global" part of dwc3 and device mode

15:21 <sven> and another one for the xhci part

15:22 <kettenis2> well, xhci is what is used for host mode

15:22 <kettenis2> and the "global" part doesn't do dma does it?

15:22 <sven> yes, but at least the linux driver tries to map some dma buffers before it gets to the xhci part

15:23 <sven> still trying to figure out if that's actually required though

15:24 <sven> i'm a little bit confused by that as well though.

15:25 <sven> all i know for sure is that if i just use the second dart for host map i get translation faults in the dart that i've been using for device mode so far

15:25 <sven> *host mode

17:28 <sven> oh for fuck's sake. after protonmail messed up yesterday now my new provider decided to send the mail as html *sigh*

21:30 <amw> Re-install MacOS into new Linux partition now can't bputil -> Failing with Error Domain=BYErrorDomain Code=401 "Failed to create local policy"

21:44 <amw> For anyone interested in helping getting bputil to work again (running latest 11.2.3 MacOS) I have the failure here http://pastie.org/p/0OJPgcw2cGwqgV2VcL6pzz

21:46 <amw> The only thing I find on google is to run csrutil disable e.g. https://apple.stackexchange.com/questions/408016/local-policy-error-when-disabling-sip-on-big-sur-m1

22:22 <marcan> well, that was a crazy lead-up to sunday alright. sorry for the downtime, back to working on asahi stuff this week :)
