2000-07-07Fix some spl handling.Artur Grabowski
Return 1 from zshard more often to reduce (not fix) the stray interrupt problem.
2000-07-07Convert spl* on sparc to be raising-only.Artur Grabowski
2000-07-06Change splsoftclock() call to spllowersoftclock() to conform with otherHakan Olsson
code and keep old behaviour. (art@ ok)
2000-07-06Add spllowersoftclock(), same as splsoftclock(). (art@ ok)Hakan Olsson
2000-07-06Use isp_handle_index functions. Reorder when things getmjacob
done (and return CMD_EAGAIN on request queue overflow so we can retry).
2000-07-05Fix spl-handling in cnstart.Artur Grabowski
2000-07-05Change splsoftclock to spltty. spltty is probably too paranoid, but it'sArtur Grabowski
less wrong than using splsoftclock which is defined to be a lowering spl (this doesn't matter on the sparc yet, because spls on sparc are wrong, but it will matter soon).

2000-06-07Fix comments to reflect reality.Artur Grabowski
2000-06-05Changes to exit handling.Artur Grabowski
cpu_exit no longer frees the vmspace and u-area. This is now handled by a separate kernel thread "reaper". This is to avoid sleeping locks in the critical path of cpu_exit where we're not allowed to sleep. From NetBSD
2000-06-02rework interrupt handling completely, and be more careful with the CD180Jason Wright
during channel configuration changes.

2000-05-01When cache is mandatory, don't pmap_enter uncached in vmapbuf.Artur Grabowski
This unbreaks physio on SM71 and SM81. Thanks to mho@ for borrowing me a cpu I could test on.
2000-03-23New API for timeouts. Replaces the old timeout()/untimeout() API andArtur Grabowski
makes it the callers responsibility to allocate resources for the timeouts. This is a KISS implementation and does _not_ solve the problems of slow handling of a large number of pending timeouts (this will be solved in future work) (although hardclock is now guarateed to take constant time for handling of timeouts). Old timeout() and untimeout() are implemented as wrappers around the new API and kept for compatibility. They will be removed as soon as all subsystems are converted to use the new API.

2000-03-17move more sun4m stuff behind an #ifdefTheo de Raadt
2000-03-16Bring in some new UVM code from NetBSD (not current).Artur Grabowski
- Introduce a new type of map that are interrupt safe and never allow faults in them. mb_map and kmem_map are made intrsafe. - Add "access protection" to uvm_vslock (to be passed down to uvm_fault and later to pmap_enter). - madvise(2) now works. - various cleanups.

2000-02-22Use an _BSD_FOO_T_ type declaration for off_t in machine/ansi.h to allowTodd C. Miller
off_t to be visible in stdio.h even in strict ansi mode. This is needed for ftello()/fseeko() and it allows us to remove the horrible fpos_t hack.
2000-02-21move fpproc into the cpuinfo structure.Artur Grabowski
2000-02-21The last pieces of hypersparc support.Artur Grabowski
- Split get_faultstatus into get_syncflt and get_asyncflt. - Get the syncflt status before setting up the trap frame and put the results in cpuinfo.syncfltdump (related to the next change). - unlock the sfsr/sfva after reading from ASI_SRMMUFP (it gets locked if the translation fails). - + other interface changes and cleanups. (most work from NetBSD).

2000-02-21When mapping something into iommu space hypersparc requires us to align itArtur Grabowski
so that cache_alias_bits match in the kernel mapping and the iommu mapping. (see code for better explaination).
