ARC: rename smp operation init_irq_cpu() to init_per_cpu()

2015-12-17T07:26:43+00:00

This will better reflect its description i.e. "any needed setup..."
and not just do an "IPI request".

ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_smp()

2015-10-28T10:43:41+00:00

MCIP now registers it's own per cpu setup routine (for IPI IRQ request)
using smp_ops.init_irq_cpu().

So no need for platforms to do that. This now completely decouples
platforms from MCIP.

ARCv2: smp: [plat-*]: No need to explicitly call mcip_init_early_smp()

2015-10-28T10:43:40+00:00

MCIP now registers it's own probe callback with smp_ops.init_early_smp()
which is called by ARC common code, so no need for platforms to do that.

This decouples the platforms and MCIP and helps confine MCIP details
to it's own file.

ARC: smp: Move default boot kick/wait code out of MCIP into common code

2015-10-17T12:18:27+00:00

For non halt-on-reset case, all cores start of simultaneously in @stext.
Master core0 proceeds with kernel boot, while other spin-wait on
@wake_flag being set by master once it is ready. So NO hardware assist
is needed for master to "kick" the others.

This patch moves this soft implementation out of mcip.c (as there is no
hardware assist) into common smp.c

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

arc/irq: Prepare idu_cascade_isr for irq argument removal

2015-07-31T20:20:05+00:00

The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.

arc:irqchip: prepare for drivers/irqchip/irqchip.h removal

2015-07-09T12:06:32+00:00

The IRQCHIP_DECLARE macro migrated to 'include/linux/irqchip.h'.

See commit 91e20b5040c67c51aad88cf87db4305c5bd7f79d
("irqchip: Move IRQCHIP_DECLARE macro to include/linux/irqchip.h").

This patch removes the inclusions of private header 'drivers/irqchip/irqchip.h'
and if necessary replaces them with inclusions of 'include/linux/irqchip.h'.

ARCv2: intc: IDU: support irq affinity

2015-07-06T05:39:02+00:00

With this nsim standlone / OSCI have working irq affinity - AXS103 still
needs some work as IDU is not visible in intc hierarchy yet !
