Working on a feasibility study for booting Linux on Apple's M5 via an XNU shim — not affiliated with Asahi Linux, exploratory research. Repo with all docs and tools: https://github.com/sasobhabha/asahi_m5
Recent changes:
– m1n1 M5 build — T8142 target, early-UART base fixed (uart0 @ 0x3A5200000, ADT ranges quirk decoded)
– SPTM stub region fully mapped — 173 stub rows + 1 inline call, three stub forms decoded (genter rows, compact GUEST rows, SK/TXM domain stubs)
– Two unpublished endpoints named from the SPTM blob's internal name table: 34 = TAG_PAPT_MULTIPAGE, 35 = UNTAG_PAPT_MULTIPAGE (new in macOS 27)
– Table 9 verdict: inactive DART generation — 13 endpoints, zero callers
Looking for testers with an M5. The README has a full workflow: build the m1n1 fork, create the stub volume, flash via 1TR, watch for UART output. Happy to help anyone who wants to try — success or crash, both are useful data.
