The kernel module now links and compiles, there are still a lot of empty TODOs left, there are empty stubs for hypertrace, assembly files and kdserial etc. these can be introduced one by one. My first step will be loading the kernel module from the userspace cli. Big step forward! :)

# The actual object list + flags live in the root Kbuild ($(ROOT)/Kbuild).
|
|
# We invoke the running kernel's build system with M= pointing at the repo
|
|
# root, so every source (hyperhv/, hyperkd/, include/, script-eval/, ...) is
|
|
# inside the module tree — no copying or symlinking of sources is needed.
|
|
#

# make # build HyperDbg.ko (lands at $(ROOT)/HyperDbg.ko)
|
|
# make clean # remove kbuild artifacts scattered under $(ROOT)

# Port workflow (compile ONE file at a time while stubbing out the WDK):

# make one FILE=include/platform/kernel/code/PlatformDpc.c

#
|
|
# 'one' compiles a SINGLE translation unit to its .o and stops — it does NOT
|
|
# link the module, so you see only that file's own compile/WDK errors instead
|
|
# of a wall of undefined-symbol link errors from the not-yet-ported files. The
|
|
# file does NOT need to be listed in $(ROOT)/Kbuild for this to work (kbuild's
|
|
# single-object target still applies the Kbuild ccflags-y include paths). Once
|
|
# a file compiles clean, move its line into the ACTIVE block of $(ROOT)/Kbuild
|
|
# and run a full `make` to fold it into HyperDbg.ko. FILE may be given as the
|
|
# .c source or the .o object; either is accepted, relative to the repo root.
