Daniel Barlow 045f10e79b build kexec statically 2023-03-24 17:12:19 +00:00
Daniel Barlow a5cfa37ed3 unify kernel command line handling
We now use MIPS_CMDLINE_DTB_EXTEND for all boot varieties
(tftpboot, flash boot, kexec) with the addition of
MIPS_BOOTLOADER_CMDLINE_REQUIRE_COOKIE - local patch -
so that the bootloader args are ignored unless they
contain the string "liminix"

Daniel Barlow 8250d592ba don't hardcode root device, too confusing when adding phram 2023-03-19 20:27:05 +00:00
Daniel Barlow 4b19568f1b add kexecboot
This allows booting a new image from a running OS, creating a
phram mtd for the root squashfs

* enable CONFIG_KEXEC
* add modules/kexecboot
* patch kexec-tools to add --map-file option for the squashfs
* patch kernel kexec code to call new kernel with DTB

Daniel Barlow b85492c744 when flashing, only need to erase the space we're writing 2023-03-18 14:50:09 +00:00
Daniel Barlow 3c6ec354ce move root's home directory to /home/root
/ is a bad choice of home directory

/home/root instead of /root is to make it easier to write
ssh keys to the right place
2023-03-18 14:46:50 +00:00
Daniel Barlow e78d5212e6 move tftp config to base module
we need it for flashing from u-boot even when tftp booting
is not enabled
2023-03-18 14:45:51 +00:00
Daniel Barlow ce05f4e44c extract phram.mtd ramdisk support from tftpboot module
also rename tftproot output to tftpboot for consistency

Daniel Barlow 3efa9e0af2 restore missing applets 2023-03-10 23:14:13 +00:00
Daniel Barlow f2d1789ad7 add openssh authorized_keys 2023-03-10 23:13:32 +00:00
Daniel Barlow 225fc6fe51 configurable busybox
allows modules to add to the busybox applets and change config

Daniel Barlow 43f1fb230b remove unrecoginsed earlyprintk param from kernel commandline 2023-03-10 00:50:28 +00:00
Daniel Barlow d83bcc643e add wifi firmware, move things around in ram
* at the base address we were using, the filesystem was getting
corrupted presumably because the kernel unpacked into it

* leave a little more space between compressed kernel and
squashfs. this is probably ineffective but also harmless

Daniel Barlow e8d5e4c788 move regulatory.db to wlan module 2023-03-07 21:32:21 +00:00
Daniel Barlow 08bed15cf8 ssh service
- dropbear
- generate host keys on first use
- mount /dev/pts

It's not ideal having the host key disappear when the device is
reboot, but without persistent storage the alternative is generating
it at build time. Deferring this problem to another time

Daniel Barlow a3cdc32142 define structured options for config.users 2023-03-04 00:24:48 +00:00
Daniel Barlow e0ea576674 rename "device" config tree as "hardware"
we are also using "device" for "network device" (as in eth0,
wlan0 etc) so this makes it a bit less confusing perhaps
2023-03-03 22:52:33 +00:00
Daniel Barlow 263882cbe4 move dts config option from boot to device 2023-03-03 22:43:44 +00:00
Daniel Barlow bbd699d7b1 add module for device-specific config
in principle this module declares the config that's defined in
devices/foo/default.nix
2023-03-03 20:04:39 +00:00
Daniel Barlow 0cd1bd99e1 declare device.flash options in base.nix
because they're specified in devices/*/default.nix

Daniel Barlow 690cedf00d better type for config.groups
instead of an attrset of anything, specify the expected
structure of each value

Daniel Barlow 751920c8fc qemu: switch to building wireless as kernel modules
This is a hefty change

* add support for kernel backports project
* build wireless stack/drivers as modules from a backported kernel
* create a service to load/unload the modules

Daniel Barlow 817c3793d4 move dts config from kernel to boot
The kernel does not need to know about the DTS. I am prepared
to be very slightly injured on this hill.

Daniel Barlow 0a06319d0c make loadAddress and entryPoint device configuration
... already having second thoughts about loadAddress
2023-02-10 18:20:01 +00:00
Daniel Barlow 8cead61740 convert devices from overlay to module
this makes it possible for devices to stash things in
`config` (e.g. pathname to DTS) that can later be overwritten
(even by the end user)

Daniel Barlow 026932a745 add unix-domain socket support
this is a curious config option to default to "n", I think
