sh64: Attempt to make reserved insn trap handler resemble C.

2012-06-14T05:46:36+00:00

This has been long overdue. No functional changes.

sh: Consolidate die definitions for trap handlers.

2012-06-14T05:18:51+00:00

This kills off the _64 versions and consolidates on the more robust _32
versions instead.

sh64: Kill off old exception debugging helpers.

2012-06-14T05:12:18+00:00

There's not much here that we can't get at through alternate means (aside
from the TLB contents, but that doesn't belong here anyways). Most of
this information is already provided by the sh32 routines, which we'll
consolidate on next.

sh64: Use generic unaligned access control/counters.

2012-06-14T05:05:24+00:00

This switches over from the special-casing that sh64 had and to the model
that's being employed for sh32.

sh64: Convert to unwinder API.

2012-05-24T06:03:46+00:00

This switches over to use the sh unwinder API which brings it all in line
with the general sh routines (which we shuffle around at the same time),
and lets us kill off more sh64-specific cruft.

sh64: Kill off unused trap_no/error_code from thread_struct.

2012-04-19T08:52:20+00:00

While the trap number and error code are passed around for debugging
purposes, this occurs wholly independently of the thread struct values.
These values were never part of the sigcontext ABI and are thus never
passed anywhere, so we can just kill them off across the board.

perf: Remove the nmi parameter from the swevent and overflow interface

2011-07-01T09:06:35+00:00

The nmi parameter indicated if we could do wakeups from the current
context, if not, we would set some state and self-IPI and let the
resulting interrupt do the wakeup.

For the various event classes:

  - hardware: nmi=0; PMI is in fact an NMI or we run irq_work_run from
    the PMI-tail (ARM etc.)
  - tracepoint: nmi=0; since tracepoint could be from NMI context.
  - software: nmi=[0,1]; some, like the schedule thing cannot
    perform wakeups, and hence need 0.

As one can see, there is very little nmi=1 usage, and the down-side of
not using it is that on some platforms some software events can have a
jiffy delay in wakeup (when arch_irq_work_raise isn't implemented).

The up-side however is that we can remove the nmi parameter and save a
bunch of conditionals in fast paths.

sh: wire up perf alignment and emulation faults.
