the attached patch implements the ETHERNET native feature as it is
implemented in ARAnyM, which should make it possible to use network
functions when runnning mint (it uses the same nfeth.xif, no changes are
To test this, i've also made an hardisk image with some rudimentry tools
that boots straight into Mint:
The archive also includes the config file. This may need some changes
regarding the ip addresses i'm using:
- 192.168.1.1 for the router
- 192.168.1.2 for the host
- 192.168.1.7 for the Hatari instance.
Unfortunately similar changes will be needed also in some files on the
and in the script i use to bring up the bridge (attached below)
Some other notes:
- the harddisk image contains a freshly compiled mint kernel, with
changes that are already pushed to the repo, but (due to bintray
closing) are not yet downloadable as snapshots.
- In aranym, 2 small helper tools are used for certain configurations
(aratapif and bpf_helper), which are not part of the patch. However that
are independent programs, and i don't expect much problems to integrate
them, but i'm just not very used to cmake to do that cleanly.
- ARAnyM uses AutoVector Interrupt #3 for the reception thread, and
calls TriggerInt3() for this purpose. In Hatari, i translated that to a
call to M68000_Exception(), i hope this is the right thing to do (but
seems to work, as seen in
- no attempt is currently made to save/restore the state from snapshots,
since i have no idea how to do that since open file descriptos are involved
- There seems to be a leak on the thread, which is not killed when
resetting the emulator (this is also present in aranym). Looks like
there is no SDL_KillThread() function in SDL2 anymore?
- I have only tested it on linux so far, but verified that the sources
for win32/macos compile at least
- i also tried to avoid some of the c++isms (like
declaration-after-statement), but it is possible that i missed some
(activating the warning did not work, because that spits out also lots
of warnings from header files).
- the ethernet_darwin.c is an older implementation, which imho isn't
used anymore (ARAnyM also unconditionally defines ENABLE_BPF for macOS,
which causes the newer implementation to be used).
thanks for your work ; Unfortunately, I don't use Mint myself, so I
can't comment whether it works OK or not, but I'm sure other users will
have a look
Just a small note regarding files : I see several ethernet*.c files with
your patch, maybe we could create an "ethernet_drivers" (or whatever
name) directory and group them all in one place ? I think it makes the
source tree easier to browse when specific parts consisting of several
files (like cpu emulation) are grouped in a single place.
