Daniel Barlow 46991e2761 aarch64 ram starts at 0x40000000 2023-11-05 15:33:10 +00:00
Daniel Barlow a135cb1217 introduce lim, the liminix library 
so far we have lim.parseInt, which parses an integer from a string
with optional base-selecting-prefix (e.g. 0755, 0x12ab)
 2023-11-05 15:13:06 +00:00
Daniel Barlow 863045b86b added hardware.ram.startAddress config 
it's not 0 on arm32, so this will be useful for qemu

Daniel Barlow e6ef4f78bb "ubimage" module contains ubifs image + instructions 
Presently either you run this from U-Boot or you figure out for
yourself how to kexecboot into a recovery system :-)
 2023-10-21 23:20:53 +01:00
Daniel Barlow f3225c2bd5 delete dup outputs.systemConfiguration 
perhaps this should go into initramfs.nix not jffs2.nix

Daniel Barlow f62ad0e1d7 use "tftpboot" instead of "tftp" in u-boot commands 
openwrt's u-boot installation doesn't accept the short form
 2023-10-09 19:47:57 +01:00
Daniel Barlow c18f07f02f aarch64: make tftpboot work 
- patch dtb to add reserved-memory stanza for the phram device to use
  (aarch64 does not accept memmap= command line option)

- patch phram driver to use memremap() instead of ioremap() as
  ioremap can't be used for system ram on arm devices

Daniel Barlow ab147abd9b less padding in firmware.bin 
we only need to align to erase block size, which may be
less than the 128k previously hard-coded

Daniel Barlow c59a228955 this is the dhcp6c service we want 2023-09-26 16:43:03 +01:00
Daniel Barlow 94e51db649 tests: use run.sh instead of calling run-liminix-vm directly 
this makes it easier to run tests on aarch64 where
qemu wants an Image file instead of a vmlinux
 2023-09-24 00:24:48 +01:00
Daniel Barlow be22fbbb0a bootable aarch64 liminux with qemu 
I may have broken the run-liminix-vm command a bit for MIPS due to
necessary changes in how we pass the command line.  If CI isn't green
for this commit and youre trying the worked examples, I suggest
reverting to the commit before this one.

Daniel Barlow f1dfb1f976 BRIDGE_VLAN_FILTERING depends on bridge _and_ vlan 
I'm half-pleased with this. It demonstrates how we can have complex
conditional kernel config, but the way we detect if vlan exists is
tacky.

Daniel Barlow 31f0213b6f convert network link/address to module-based-service 
... and make bridge use it.

We also had to convert bridge back into a pair of services.
Downstreams want to depend on the bridge it self being configured
even if not necessarily all the members are up. e.g. don't want
to break ssh on lan if there's a misconfigured wlan device
 2023-08-28 22:02:28 +01:00
Daniel Barlow 540a1dfd76 remove interface.device 
build-time uses can mostly be replaced with interface.name

for runtime uses, switch to $(output ${interface} name)

Daniel Barlow b81604870b extract kernel config options from base module 
we then "import" them straight back into base.nix - it's not
as though you can opt out of having a kernel. But this means
they'll appear separately in the documentation

 2023-08-05 12:07:35 +01:00
Daniel Barlow fbb2c04132 move module-based-service parameter types into service 
This is in preparation for writing something that extracts them
into documentation.

user configurations now call config.system.service.foo.build { ...params }
instead of config.system.service.foo

the parameter type definitions themselves now move into the
config stanza of the module referencing the service

new helper function  liminix.callService

The only service moved so far is dnsmasq

Daniel Barlow 69e6eb5a89 accept attr args to pppoe service, and typecheck them 
We use (abuse, arguably) the nixos module system for typechecking.  Un
the plus side, it gives us documentation of the options and their
expected types. On the downside, the error message doesn't tell us
the file in which the error was encountered.

(This is subject to change, if I can find a better way)
 2023-07-14 16:53:36 +01:00
Daniel Barlow 9441f48819 new ppp module, used by rotuer 
The objective here is that services which depend on global config
(e.g. kernel config or busybox options or static paths in the
filesystem) now live under config.system.service, and are added
to that collection by the module that defines the necessary state.

This is a first step: the services will be configured by a typechecked
attr set instead of the arbitrary arguments that
pkgs.liminix.networking.pppoe accepts
 2023-07-13 19:44:14 +01:00
Daniel Barlow 2e50368bd2 rename config.outputs to config.system.outputs 
New rules: everything under "config" that isn't actually configuration
(e.g. build products) will in future live in config.system. This is
the first step.

Daniel Barlow 447f068569 partly support getting IPv6 addresses 
- gets interface id from ppp
- runs odhcpc to get RA and prefix delegation
- doesn't do anything useful with the data yet
