sparc/irq: Use helper irq_data_get_irq_handler_data()

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

Use helper function irq_data_get_irq_handler_data() to hide irq_desc
implementation details. This allows to move irq_data->handler_data to
irq_data_common, once all usage sites are converted.

sparc32: remove remaining users of btfixup

2012-05-14T21:05:08+00:00

Use sparc_config to hold the last two function pointers.  There was no
point generating dedicated _ops structures only for these.

sparc32: move smp ipi to method ops

2012-05-14T21:05:07+00:00

I ended up renaming set_cpu_int to send_ipi to
be consistent all way around.
send_ipi was moved to the *_smp.c files so
we could call the relevant method direct,
without any _ops indirection.

sparc32: Move cache and TLB flushes over to method ops.

2012-05-14T03:49:31+00:00

This eliminated most of the remaining users of btfixup.

There are some complications because of the special cases we
have for sun4d, leon, and some flavors of viking.

It was found that there are no cases where a flush_page_for_dma
method was not hooked up to something, so the "noflush" iommu
methods were removed.

Add some documentation to the viking_sun4d_smp_ops to describe exactly
the hardware bug which causes us to need special TLB flushing on
sun4d.

sparc32: generic clockevent support

2012-04-15T17:28:50+00:00

The kernel uses l14 timers as clockevents. l10 timer is used
as clocksource if platform master_l10_counter isn't constantly
zero. The clocksource is continuous, so it's possible to use
high resolution timers. l10 timer is also used as clockevent
on UP configurations.

This realization is for sun4m, sun4d, sun4c, microsparc-IIep
and LEON platforms. The appropriate LEON changes was made by
Konrad Eisele.

In case of sun4m's oneshot mode, profile irq is zeroed in
smp4m_percpu_timer_interrupt(). It is maybe
needless (double, triple etc overflow does nothing).

sun4d is able to have oneshot mode too, but I haven't
any way to test it. So code of its percpu timer handler
is made as much equal to the current code as possible.

The patch is tested on sun4m box in SMP mode by me,
and tested by Konrad on leon in up mode (leon smp
is broken atm - due to other reasons).

sparc32: rename sparc_irq_config to sparc_config

2012-04-15T17:28:49+00:00

This struct holds platform specific config and is thus not
limited to irq stuff.
Do not let the name confuse us to think this is irq only.
