John Polstra 317c91f4d4 Make ELF kernels build again. 1998-08-16 04:19:03 +00:00
Bruce Evans 18c5a6c435 Implemented dynamic registration of software interrupt handlers. Not 
used yet.

Use dummy SWI handlers to avoid some checks for null pointers.

Tor Egge 5931a9c24e For SMP, use prv_PPAGE1/prv_PMAP1 instead of PADDR1/PMAP1. 
get_ptbase and pmap_pte_quick no longer generates IPIs.
This should reduce the number of IPIs during heavy paging.

Poul-Henning Kamp 00af9731c9 Time changes mark 2: 
* Figure out UTC relative to boottime.  Four new functions provide
      time relative to boottime.

    * move "runtime" into struct proc.  This helps fix the calcru()
      problem in SMP.

    * kill mono_time.

    * add timespec{add|sub|cmp} macros to time.h.  (XXX: These may change!)

    * nanosleep, select & poll takes long sleeps one day at a time

Poul-Henning Kamp 71f461f86a Rename "i586_ctr" to "tsc" (both upper and lower case instances). 
Fix a couple of printfs too.

Warning: This changes the names of a couple of kernel options!

cam_imask when compiling under elf.

Peter Wemm 88d2e69daa Update to include recently added names that are shared between the C and 
asm parts of the kernel.  This is to re-enable ELF compile support.

Peter Wemm b3196e4b9f Preliminary support for per-cpu data pages. 
This eliminates a lot of #ifdef SMP type code.  Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like:    #define curproc (SMPcurproc[cpunumber()])

There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work.  There is still some
strictly temporary code present that isn't exactly pretty.

This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe.  The temporary code goes away when the
full idle cpu support is finished.

Steve Passe f7ef1c65a1 Removed global hwisrs, replacing it with vec (formerly static to icu.s). 1997-05-25 16:58:03 +00:00
John Polstra 9e86cdb740 Add new C global names also referenced from assembly language. 
These mostly came from the addition of SMP support.

John Polstra 9081eec1fb Make the necessary changes so that an ELF kernel can be built. I 
have successfully built, booted, and run a number of different ELF
kernel configurations, including GENERIC.  LINT also builds and
links cleanly, though I have not tried to boot it.

The impact on developers is virtually nil, except for two things.
All linker sets that might possibly be present in the kernel must be
listed in "sys/i386/i386/setdefs.h".  And all C symbols that are
also referenced from assembly language code must be listed in
"sys/i386/include/asnames.h".  It so happens that failure to do
these things will have no impact on the a.out kernel.  But it will
break the build of the ELF kernel.

The ELF bootloader works, but it is not ready to commit quite yet.
