Daniel Barlow 4638092d3d build initramfs into kernel 
this doesn't matter for qemu, but there's no other way of
getting a hardware device to find it if the bootloader
won't co-operate
 2023-04-10 22:57:50 +01:00
Daniel Barlow 633a4f8003 move BLK_DEV_INITRD to base.nix 2023-04-10 22:57:50 +01:00
Daniel Barlow 42725f56f9 make jffs2 module provide o.rootfs, conditionally 
it's enabled if config.rootfsType == "jffs2"
 2023-04-10 20:01:58 +01:00
Daniel Barlow 63a89f7d0d add config.boot.initramfs.enable 2023-04-10 19:07:27 +01:00
Daniel Barlow 07eb3d66da remove unused combined-image output 2023-04-10 18:15:48 +01:00
Daniel Barlow 0687ae7f5c rename flashable->flashimage, o.squashfs to rootfs 
"rootfs" describes what it is for, "squashfs" merely says
how it's implemented

(also, rootfs-as-jffs2 will soon be added)
 2023-04-10 18:13:27 +01:00
Daniel Barlow f5156425a2 correct jffs2 endian, remove unused bindings 2023-04-07 09:39:47 +01:00
Daniel Barlow 54a1ab3529 support jffs2, with initramfs 
the jffs2 filesystem contains only /nix/store and a script which is
run in early init (initramfs) and is responsible for recreating
"traditional" directories (/bin /etc/**/* /var &c) based on the
configuration.

this is tested only in qemu so far and could use some cleanup
 2023-04-04 23:35:49 +01:00
Daniel Barlow 25d9da967c remove support for sockets in pseudofiles 
(1) we can't make them on a real filesystem except by running
something that calls socket()
(2) whyever would we want to?
 2023-04-04 23:23:22 +01:00
Daniel Barlow f5a7b78679 rename kexec-tools-static 
it doesn't build natively on x86-64 and I don't suppose we need it to
anyway
 2023-03-24 20:51:46 +00:00
Daniel Barlow c831859513 add flashcp to allow flashing from a running system 2023-03-24 17:32:46 +00:00
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"
 2023-03-23 22:24:44 +00:00
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
 2023-03-19 20:25:43 +00:00
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 225fc6fe51 configurable busybox 
allows modules to add to the busybox applets and change config
 2023-03-10 18:40:45 +00:00
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
 2023-03-10 00:48:47 +00:00

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
 2023-03-04 12:10:06 +00:00
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
 2023-02-25 20:33:18 +00:00
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
 2023-02-22 18:41:41 +00:00

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.

... 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)
