b701be7c86 Use atomic operations to manipulate the SSIR, and fix a problem introduced 
with the spllowersoftclock() changes where more interrupts than necessary
were blocked while software interrupts were being processed.

ede200e1ab Add a driver for the Tadpole SPARCbook microcontroller. It doesn't 
do much yet (except for power down support).  As sson as I figure
out to get its interrupts enabled, it will be much more functional.
(e.g., print console messages on low power warnings, be able to turn
off the TFT, etc.).

84e306ed83 Tadpoles don't use the standard sun4m power down hardware. So add 
support for doing it the Tadpole way.

1b0bd3757f add entries for the tadpole microcontroller (tctrl) and the 
tadpole pcmcia controller (tpcic).  Drivers for the former will
show up today, and the latter later this week or next weekend.

26297cb6e9 PR/8178:Julian Coleman: sparc kernel will not build with cgtwo/cgsix but 
without sbus. Remove call to cgsix-sbus-attach (impossible code). Make
routines static (they were declared static, but not defined static and
some compilers can complain).

54f2532106 Change the way that bit's are cleared in the InterruptPending register of 
the 68901. Do this now by _assigning_ ~<bit_to_clear> instead of the
previously used 'andb ~<bit_to_clear>'. The latter caused a rwm-cycle that
caused a race condition to happen when an interrupt arrived between the
Read and Modify-Write.
Anyway, this solved my hanging keyboard problem.

2ff657adb8 Fix the raise/lower semantics of splsoftclock()/spllowersoftclock(). 1999-08-05 18:28:01 +00:00
thorpej
eb20bbc780 Change the semantics of splsoftclock() to be like other spl*() functions, 
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their
XXX spl*() functions are fixed.
