bunnie	c0484ca607	chore: fix formatting	2024-03-23 12:02:54 +08:00
bunnie	8b7912fb34	add some targeted debug; handle advisories before swapper registered ... for now, we just count how mayn pages we missed an advisory on, those all effectively are "wired". If we're fast enough on registering, it turns out we actually miss nothing.	2024-03-23 11:59:31 +08:00
bunnie	233bb63878	add debug-swap targeted debug config	2024-03-23 11:59:31 +08:00
bunnie	10c4ab80c8	make the swapper register immediately ... this means we miss fewer advisories at boot	2024-03-23 11:59:31 +08:00
bunnie	ed5dd7e538	fix argument order bug ... just a dumb typo	2024-03-23 11:59:31 +08:00
bunnie	ced6dd9e63	fix bug in create-image invocation ... its arguments require the 0x decorator to define hex, whereas arguments to xtask don't. A little confusing, but only if you actually ever call create-image -- which nobody does, to a first order.	2024-03-23 11:59:31 +08:00
bunnie	fdbdea5ab0	add swap tag to image creation	2024-03-23 11:59:31 +08:00
bunnie	38f0002294	partial progress on create-image ... create-image can now genereate inis sections still needs to kick out a `swap` argument for the bootloader so it knows where swap should go.	2024-03-23 11:59:31 +08:00
bunnie	66779dd479	add swap specifiers to xtask	2024-03-23 11:59:31 +08:00
bunnie	ff241b117b	fix ordering of processes so that the swapper is PID 2	2024-03-23 11:59:31 +08:00
bunnie	71b3244198	add "swap" to the arguments for syntax checking ... doesn't hurt, makes it easier to debug things	2024-03-23 11:59:31 +08:00
bunnie	9ddf537115	setup argument unpacking in the swapper	2024-03-23 11:59:31 +08:00
bunnie	803ce1a847	move allocadvice to new home	2024-03-23 11:59:31 +08:00
bunnie	b62a639031	move AllocAdvice record to externally visible xous-rs definitions ... this structure moves between swapper and userland.	2024-03-23 11:59:31 +08:00
bunnie	a2e6a75b2d	add test code to lock and top level workspace	2024-03-23 11:59:31 +08:00

bunnie	21338321cd	add a skeleton for swapper test code	2024-03-23 11:59:31 +08:00
bunnie	c2084af2ad	make sure the swapper feature is turned on	2024-03-23 11:59:31 +08:00
bunnie	af856124a0	pass kernel dependency to xous-rs	2024-03-23 11:59:31 +08:00

bunnie	b2cd829adb	upgrade api to use the new irq enum discipline ... I think this commit message got swapped with the previous one, the hazards of autocomplete.	2024-03-23 11:59:31 +08:00
bunnie	167cd04f06	remove arg page list, replace with set of 8 usize ... this makes calls more efficient and avoids the double-shared page	2024-03-23 11:59:31 +08:00
bunnie	d6cfb13e4f	upgrade irq path to handle the new API	2024-03-23 11:59:31 +08:00

bunnie	500a641848	specify the irq return address for irqs	2024-03-23 11:59:31 +08:00

bunnie	65599a46d5	add state and handler to the setup ... shared state is going to be much more complicated, for now, just a placeholder	2024-03-23 11:59:31 +08:00
bunnie	fac6a43b19	add arguments for handler and state to registration	2024-03-23 11:59:31 +08:00

bunnie	47a16b6ce4	add RETURN_FROM_ISR magic address ... this is picked to not conflict with other addresses used by the ARM implementation. I think it should be OK?	2024-03-23 11:59:31 +08:00
bunnie	26047bf956	add the routine to evict a page	2024-03-23 11:59:31 +08:00

bunnie	5c3edef519	define initial data structures & registration ... note that the SMT is a trait that has an implementation dependent structure, because we can't always assume that swap is memory-mapped.	2024-03-23 11:59:31 +08:00
bunnie	496d13b157	create swapper syscall entries; implement RegisterSwapper	2024-03-23 11:59:31 +08:00
