10:16 <robinp_> what are the m1n1 proxy device names for macOS ?

10:24 <VinDuv> cu.usbmodem_01 and 03 IIRC

11:19 <robinp_> VinDuv: ah cu.usbmodemP_01 & 03 - but had no change to find them without your help :)

11:19 <robinp_> *chance

12:20 <robinp_> is it me, or is checking for files in zsh using [ ! -e foo ] broken in macOS 12.3 ?

12:21 <dottedmag> robinp_: looks fine here. any specifics, or a reproducer?

12:24 <robinp_> dottedmag: I was trying it with the m1n1 proxy latch script, and I just tried with a quick test script. It seems it works if I use a variable and do say [ ! -e "$file" ], but naming the file directly doesn't work.

12:46 <robinp_> `if` seems to work, but not `while` - this is what I am doing https://paste.debian.net/1237474/

12:47 <VinDuv> hmm I think you need to put the do before the echo

12:48 <robinp_> ah

12:53 <VinDuv> Yeah it looks like the do delimitates the end of the condition expression, so in your case the condition of the while loop is “[ ! -e foo ]; echo "File not found";” which is equivalent to “echo "File not found";” which is always true

12:53 <VinDuv> (TIL :) )

14:08 <jannau> I still don't see anything in the ADT which helps to deal with the magically present pgmr on the second die. we could infer the offset from ranges but it's a little annoying

14:09 <jannau> I don't see anything in the pgmr ADT node to indicate whether devices are present on either die

14:09 <sven> maybe it's hardcoded in the kext :/

14:13 <j`ey> jannau: why cant we just put it in our DTS?

14:23 <jannau> it's not a problem for now just annoying. it looks like it's the easiest way to hardcode it in m1n1 as well until a 4 die SoC arrives

14:23 <jannau> for pgmr we probably have to assume that always-on is correct and everything else can be disabled if there is no device using it

20:15 <jannau> lol, I can crash dcp in way which doesn't keeps the display scanout working. In that state I can turn the monitor off and on without breaking the display

20:22 <jannau> sigh, HV + macos guest works on the m1 ultra if I don't initialize the display / map the framebuffer

20:27 <jannau> but it is so slow that it panics on shutdown with "Halt/Restart Timed Out @IOPlatformExpert.cpp:883"

21:02 <jannau> panic with initialized display is the AMCC UNEXP_RT_HIT_DIR with an address inside dart-disp0's first page table for dev 0

21:08 <jannau> indication that BIT(1) of dart-t6000 is indeed uncached: iboot/macos set it for dcp/disp0 but not for dart-usb

21:51 <jannau> marcan: refreshed t6002-bringup branch pushed. not fully happy with the multi-die pmgr handling, macos guest handling still needs work

21:52 <jannau> https://github.com/jannau/m1n1/tree/t6002-bringup

22:35 <j`ey> no idea why hv would be slower on the ultra..
