[PATCH] powerpc: remove useless call to touch_softlockup_watchdog

2006-02-07T10:32:44+00:00

It turns out that we can't stop the watchdog from
triggering here.  If we touch the timer (which just uses the current jiffie
value) before we enable interrupts, it does nothing because jiffies
are not mass-updated until after we enable interrupts.  If we touch the
timer after we enable interrupts, its too late because the softlockup
watchdog will already have triggered.  The touch_softlockup_watchdog
call removed below does nothing.

[PATCH] powerpc: prod all processors after ibm,suspend-me

2006-02-07T10:32:43+00:00

We need to prod everyone here since this is the only CPU that is
guaranteed to be running after the ibm,suspend-me RTAS call returns.

[PATCH] powerpc: return correct rtas status from ibm,suspend-me

2006-02-07T10:32:43+00:00

Correctly return the status from the RTAS call.  rtas_call expects
to return the status as a return value.

[PATCH] powerpc: Fix !SMP build of rtas.c

2006-02-07T10:28:38+00:00

arch/powerpc/kernel/rtas.c is getting hvcall.h via spinlock.h, but when we're
building for UP we don't include spinlock.h.

[PATCH] powerpc: special-case ibm,suspend-me RTAS call

2006-01-14T01:04:25+00:00

Handle the ibm,suspend-me RTAS call specially.  It needs
to be wrapped in a set of synchronization hypervisor calls
(H_Join).  When the H_Join calls are made on all CPUs, the
intent is that only one will return with H_Continue, meaning
that he is the "last man standing".  That CPU then issues the
ibm,suspend-me call.  What is interesting, of course, is that
the CPU running when the rtas syscall is made, may NOT be the
CPU that ultimately executes the ibm,suspend-me rtas call.

[PATCH] powerpc: Make early debugging configurable via Kconfig

2006-01-11T03:48:26+00:00

This patch adds Kconfig entries to control the early debugging options,
currently in setup_64.c.

Doing this via Kconfig rather than #defines means you can have one source tree,
which is buildable for multiple platforms - and you can enable the correct
early debug option for each platform via .config.

I made udbg_early_init() a static inline because otherwise GCC is to daft to
optimise it away when debugging is off.

Now that we have udbg_init_rtas() we can make call_rtas_display_status* static.

[PATCH] powerpc: merge code values for identifying platforms

2005-11-10T02:37:51+00:00

This patch merges platform codes.  systemcfg->platform is no longer used,
systemcfg use in general is deprecated as much as possible (and renamed
_systemcfg before it gets completely moved elsewhere in a future patch),
_machine is now used on ppc64 along as ppc32.  Platform codes aren't gone
yet but we are getting a step closer. A bunch of asm code in head[_64].S
is also turned into C code.
