[PATCH 00/13] disentangling cyclic API from schedule()

[PATCH 00/13] disentangling cyclic API from schedule()

[Rasmus Villemoes]

These patches are part of a longer-term plan to properly deal with the
HW_WATCHDOG vs WATCHDOG dichotomy, and getting rid of the legacy
HW_WATCHDOG concept completely. As part of that, clean up which
headers include other headers.

While schedule(), the artist formerly known as WATCHDOG_RESET(), is
obviously called all over the tree, very few TUs make use of the
cyclic API (cyclic_register etc.). And there's really no reason at all
for global_data.h to include cyclic.h - except that some places
implicitly rely on getting their declaration of schedule() through
that include.

So this introduces a separate mostly trivial header that just serves
to declare schedule(). Then we can get rid of things that include
cyclic.h just to get that declaration.

A next, mostly mechanical step, could be to change almost all includes
of watchdog.h (which most TUs that used to have a WATCHDOG_RESET()
invocation has) to u-boot/schedule.h, because again, most of those TUs
are not really concerned with implementing init_func_watchdog_init or
need to call it. But that is for later.

CI seems happy: https://github.com/u-boot/u-boot/pull/673

[PATCH 01/13] doc: cyclic: remove reference to WATCHDOG_RESET

[Rasmus Villemoes]

WATCHDOG_RESET is no more. Replace the reference by schedule().

While here, rearrange the sentence a bit so that "cyclic_run()"
becomes the object and "the main function responsible for calling all
registered cyclic functions" a parenthetical rather than the other way
around, which at least to me makes it more readable.

[PATCH 02/13] cyclic: introduce u-boot/schedule.h

[Rasmus Villemoes]

I noticed an "unnecessary" include of <cyclic.h> in
global_data.h, in the sense that nothing in cyclic.h is needed in
order to define 'struct global_data'.

Well, it's not unnecessary, as it implicitly ensures that everybody
gets a declaration of schedule(), and schedule() is (obviously) called
all over the tree. Almost none of those places directly include
<cyclic.h>, but for historical reasons, many do include
<watchdog.h> (most schedule() instances are replacements of
WATCHDOG_RESET()).

However, very few TUs actually need the declarations of the
cyclic_register() and struct cyclic_info, and they also don't really
need anything from the watchdog.h header.

So introduce a new header which just contains a declaration of
schedule(), which can then be included from all the places that do
call schedule(). I removed the direct reference to cyclic_run(),
because we shouldn't have two public functions for doing roughly the
same without being very explicit about when one should call one or the
other.

Testing of later patches that explicitly include <schedule.h> when
schedule() is used revealed a problem with host tool build on win32,
which apparently picked up a host <schedule.h>. To avoid that problem,
put the new header in include/u-boot/ and hence make the include
statements say <u-boot/schedule.h>.

[PATCH 04/13] m68k: asm/ptrace.h: include linux/types.h

[Rasmus Villemoes]

Modifying a generic header like watchdog.h, removing not directly used
#includes, can apparently break the build of m68k, because the
asm/ptrace.h header relies on whoever includes it to already have
included something that defines the type ulong.

Make the asm/ptrace.h header self-contained by including the proper
header.

[PATCH 05/13] fs/cramfs: use schedule instead of cyclic_run as callback

[Rasmus Villemoes]

Prior to commit 29caf9305b6f ("cyclic: Use schedule() instead of
WATCHDOG_RESET()") we had

/* Currently only needed for fs/cramfs/uncompress.c */
static inline void watchdog_reset_func(void)
{
       WATCHDOG_RESET();
}

and .outcb was set to that watchdog_reset_func().  Said commit changed
that .outcb to cyclic_run instead of schedule, which would otherwise
match all the other WATCHDOG_RESET replacements done. As the
HW_WATCHDOG case is not handled by cyclic_run, this seems to be an
oversight.

[PATCH 08/13] watchdog.h: change include of cyclic.h to u-boot/schedule.h

[Rasmus Villemoes]

Nobody relies on getting the cyclic API declared by including the
watchdog.h header, but for historical reasons, many TUs include
watchdog.h to get a declaration of schedule(). Now that we have a
dedicated header for just that, include that header instead of
cyclic.h.

Eventually, all TUs that call schedule() should themselves include
u-boot/schedule.h, but this is a step towards getting rid of
unnecessary include statements in cyclic.h and global_data.h.

I think the last paragraph in the commit message should answer that:

>> Testing of later patches that explicitly include <schedule.h> when
>> schedule() is used revealed a problem with host tool build on win32,
>> which apparently picked up a host <schedule.h>. To avoid that problem,

So I tried that at first, and it worked fine for all my local builds,
but the CI told me it couldn't. I can try to find the old github PR
where I got the CI to tell me this (it's months ago I started doing
this), but I don't know if the azure logs still exist.
