- UTSM panic_full returns in fallback mode (logs [PANIC:FALLBACK] + code + hit count); panic_halt keeps always-halt sites (CPU exception, VMM-E11 LA57, VMM-E15 DSK jump, UTSM-E42 test hook). Call sites given safe continuations. - Mode passed to DSK/FirstInit/login/desktop via DSK_BOOT_FLAG_PANIC_FALLBACK; DKM kernel_api.panic / kern.log.panic return to driver; ext4 fatal aborts the op via setjmp/longjmp and DSK falls back to FAT32 ESP. - build.ps1/Makefile: dev=strict, release=fallback, new realtest (release options + strict); default -Variant all; serialized iso packing under -j. - Fix '*/' inside comments (dkm.h, kernel_api.h, bus.c) that broke the build. - Includes pending work: dkm_bus service bus, mt7920/wlan drivers, desktop files/startmenu/prank, pe-tools, diskinfo, docs.

# Linux 6.6 LTS guest kernel (UTSM+Linux dual-kernel Linux compat layer)

# Uncomment after building Linux via CODE/linux/build.sh (requires WSL/Linux).
|
|
#
|
|
# Boot flow with these modules:
|
|
# 1. Limine loads utsm.elf + all .drv modules + bzImage + initrd
|
|
# 2. UTSM boots, init VMM/EPT, self-test
|
|
# 3. UTSM linux_loader_init() finds bzImage module, parses + maps guest
|
|
# 4. UTSM ipc_shm_init() allocates 1MB IPC shared memory (EPT-mapped)
|
|
# 5. UTSM linux_launch() → vmlaunch → Linux boots → init starts daemon
|
|
# 6. Daemon sends EXEC_READY, then ioctl(PARK) → HLT → VM-Exit → park
|
|
# 7. UTSM linux_compat_init() marks Linux compat layer ready
|
|
# 8. UTSM loads DSK (deshab.elf) → shell.elf → `linux <prog>` command
|
|
# invokes linux_compat_service->exec() → vmresume → daemon runs prog
|
|
#
|
|
# Linux 兼容层模块（需先通过 WSL 运行 CODE/linux/build.sh 构建产物）

# build.sh 成功后会自动取消下面 4 行注释；若未构建 Linux 内核请保持注释状态
