ARM: 7293/1: logical_cpu_map: decouple CPU mapping from SMP

2012-01-23T10:20:05+00:00

It turns out that the logical CPU mapping is useful even when !CONFIG_SMP
for manipulation of devices like interrupt and power controllers when
running a UP kernel on a CPU other than 0. This can happen when kexecing
a UP image from an SMP kernel.

In the future, multi-cluster systems running AMP configurations will
require something similar for mapping cluster IDs, so it makes sense to
decouple this logic in preparation for this support.

Merge branch 'fixes-for-arm-soc' of git://sources.calxeda.com/kernel/linux into fixes

2012-01-17T06:46:06+00:00

* 'fixes-for-arm-soc' of git://sources.calxeda.com/kernel/linux:
  ARM: make BSYM macro assembly only
  ARM: highbank: remove incorrect BSYM usage
  ARM: imx: remove incorrect BSYM usage
  ARM: exynos: remove incorrect BSYM usage
  ARM: ux500: add missing ENDPROC to headsmp.S
  ARM: msm: Add missing ENDPROC to headsmp.S
  ARM: versatile: Add missing ENDPROC to headsmp.S

ARM: versatile: Add missing ENDPROC to headsmp.S

2012-01-16T14:35:25+00:00

Once the ENDPROC is in place, BSYM() in not longer necessary
to get correct pointer to versatile_secondary_startup().

ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime

2011-12-18T23:00:26+00:00

sched_clock() is yet another blocker on the road to the single
image. This patch implements an idea by Russell King:

http://www.spinics.net/lists/linux-omap/msg49561.html

Instead of asking the platform to implement both sched_clock()
itself and the rollover callback, simply register a read()
function, and let the ARM code care about sched_clock() itself,
the conversion to ns and the rollover. sched_clock() uses
this read() function as an indirection to the platform code.
If the platform doesn't provide a read(), the code falls back
to the jiffy counter (just like the default sched_clock).

This allow some simplifications and possibly some footprint gain
when multiple platforms are compiled in. Among the drawbacks,
the removal of the *_fixed_sched_clock optimization which could
negatively impact some platforms (sa1100, tegra, versatile
and omap).

Tested on 11MPCore, OMAP4 and Tegra.

ARM: versatile: convert logical CPU numbers to physical numbers

2011-10-17T09:01:11+00:00

This patch uses the new cpu_logical_map() macro for converting logical
CPU numbers into physical numbers when dealing with the pen_release
variable in the SMP boot and CPU hotplug paths.

ARM: consolidate SMP cross call implementation

2011-05-23T15:53:17+00:00

Rather than having each platform class provide a mach/smp.h header for
smp_cross_call(), arrange for them to register the function with the
core ARM SMP code instead.

arm: Cleanup the irq namespace

2011-03-29T12:47:57+00:00

Convert to the new function names. Automated with coccinelle.

ARM: 6759/1: smp: Select local timers vs broadcast timer support runtime

2011-02-23T17:54:27+00:00

The current code support of dummy timers in absence of local
timer is compile time. This is an attempt to convert it to runtime
so that on few SOC version if the local timers aren't supported
kernel can switch to dummy timers. OMAP4430 ES1.0 does suffer from
this limitation.

This patch should not have any functional impact on affected
files.

ARM: integrator: add Integrator/CP sched_clock support

2011-02-19T11:11:46+00:00

Integrator/CP has the 24MHz counter which Versatile and later platforms
also have, which we use for sched_clock support.  Allow this counter to
be used when building a kernel targetting Integrator/CP alone.
Integrator/AP does not have this counter, so we must exclude support
for the Integrator family when this is enabled.
