* common: move workqueue handling from poller_call() to sched()Ahmad Fatoum2021-06-251-0/+5
| | | | | | | | | | | | | | | Workqueues are run out of poller_call, not because of a dependency, but because when they were added, poller_call was directly called from is_timeout. With the addition of bthreads, there is now a general resched() function that runs pollers and switches between bthreads. It makes sense to move workqueue handling there as well to keep scheduling matter contained in a single function. Do so.

| * common: add generic system partitions interfaceAhmad Fatoum2021-05-121-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both Fastboot and DFU have their own global variables that allow specifying the partitions that can be flashed via the environment. With the upcoming addition of the USB mass storage gadget, we will need some way to define the partitions there as well. Instead of adding yet another way download method-specific variable, add a generic global.system.partitions variable that can be specified on a per-board basis and can be used for all methods. Existing variables will still remain for backwards-compatibility, but when unset, it should fall back to this new parameter. This is done in the follow-up patches.

* / fs: add linux_rootarg 'root=mmcblkXpN' supportMarco Felsch2021-05-121-0/+21
|/ | | | | | | | | | | | | | | | | | | Since commit fa2d0aa96941 ("mmc: core: Allow setting slot index via device tree alias") the linux kernel supports stable mmc device names. Barebox has stable names since years so now we can connect both which allows us to pass 'root=mmcblkXpN' as argument for the cmdline. Note: it is crucial that the kernel device tree and the barebox device tree uses the same mmc aliases. This patch adds the support to store the above cmdline as linux_rootarg if enabled. The partuuid is now used as fallback since it is not as unique as the mmcblkXpN scheme. It is added as build option since the system integrator needs to check if the used kernel contains the above commit.

| * common: introduce bthreads, co-operative barebox threadsAhmad Fatoum2021-03-221-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the new setjmp/longjmp/initjmp support, we have all the architecture support in place to have suspendable green threads in barebox. These are expected to replace pollers and workqueues. For now we still have a differentiation between the main and secondary threads. The main thread is allowed I/O access unconditionally. If it's in a delay loop, a secondary thread running needs to be wary of not entering the same driver and doing hardware manipulation. We already have slices as mechanism to guard against this, but they aren't used as widely as needed. Preferably, in the end, threads will automatically yield until they can claim a resource (i.e. lock a mutex). Until we are there, take the same care when using bthreads as with pollers.

This is why we already have a setjmp/longjmp ARM - Do exception handling[1] - Port over scripting language VMs that use sjlj for context switching - Implement stackless coroutines in C. These coroutines would be stackless, because jumping to a setjmp down the call stack means that the code there will clobber the stack below it. On resuming the coroutine, it will run with a stack changed in the interim leading to undefined behavior. There are ways around that without resorting to custom Assembly: - Allocate a buffer on the scheduler's stack, so coroutine can grow into them -> Problem: exploits Undefined behavior - Yield first time on scheduler stack, then patch jmp_buf to point at another stack -> Problem: Code switching stacks should not itself use the stack - Construct a new jmp_buf with user-supplied return address and stack top: int initjmp(jmp_buf jmp, void __noreturn (*func)(void), void *stack_top); The latter could also be reused as a portable way of setting up a stack in early init code. We are going to implement green threads in later commits, so add a symbol that can be selected to indicate architecture support for setjmp, longjmp and the new initjmp.

* boot: introduce option to pass barebox-enabled watchdog to systemdAhmad Fatoum2020-11-301-0/+10
| | | | | | | | | | | | | | | | | Like Linux, barebox supports co-existence of multiple watchdog devices. On boot, barebox enables only the default watchdog, which is defined as the watchdog with highest non-zero priority. The kernel handles all watchdogs the same and defers to userspace, which watchdogs to service. It can be useful to have barebox tell the system, which watchdog it activated, so it can service the same. Having this feature behind a global variable adds 354 bytes to a LZO compressed THUMB2 barebox. Users can opt out by toggling the Kconfig option, which defaults to off.

The hush syntax doesn't allow for setting all kinds of environment variables though, e.g. 5c00a000.tamp@5c00a000:reboot-mode.of.param can't be set with hush, because of the special characters. It could still be read by using the ${variable} syntax though. Allow setting these variables by making the setenv command generally available.
