kristerw d320ba3418 Use "__asm __volatile" instead of "asm volatile" to pacify lint. 2002-12-29 14:40:35 +00:00
manu 4a06119a9d Pass the system call table to trace_enter() and ktrsys() so that it is
possible to use alternate system call tables. This is usefull for
displaying correctly the arguments in Mach binaries traces.

If NULL is given, then the regular systam call table for the process is used.

thorpej e8cc3884de Rename __LDPGSZ to AOUT_LDPGSZ, to accurately reflect what it is. 2002-12-10 17:14:02 +00:00
lukem 0635de35a3 Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more. 2002-11-26 23:30:07 +00:00
manu d584ed9598 Add a realcode argument to trace_enter and ktrsyscall. realcode is the
original system call number, which can be negative for a Mach trap.
We cannot just replace code by realcode, because ktrsyscall uses it as
an index in the system call table, thus crashing the kernel when the
value is negative.

chs 42a0d8fa15 use "static __inline" instead of "extern __inline" so that we can
build without optimization.

chs 40e5b8394f finish conversion to the common m68k cacheops:
add support for machine-specific flavors of the ops for off-chip caches.
many thanks to Izumi Tsutsui for his help with this.

jdolecek 405d32e2db g/c local offsetof(), it's defined in libkern.h 2002-10-26 13:24:55 +00:00
chs 1c2419d28a merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
 - use m68k/cacheops.*, remove duplicates from cpu.h.
 - centralize a few declarations in (all the copies of) cpu.h.
 - define M68K_VAC on platforms which have a VAC.
 - switch the sun platforms to the (now common) proc_trampoline().
 - do the phys_map thang on the sun platforms too, no reason not to.

gmcgarry dca80f08fd Add __HAVE_MD_RUNQUEUE flag for MD code to override MI run queue primitives. 2002-09-22 04:11:32 +00:00
briggs 0b956d0b8b Implement pmc(9) -- An interface to hardware performance monitoring
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.

scw bef00d4895 m68k syscall rototill:
- Switch all m68k-based ports over to __HAVE_SYSCALL_INTERN.
 - Add systrace glue.
 - Define struct mdproc in <m68k/proc.h> instead of <machine/proc.h>.
   (They were all defined exactly the same anyway, other than a couple
   of the MDP_* flags.)

scottr 3b09fcde6d Correct misplaced #endif that causes compile-time error if
neither M68040 nor M68060 are configured into the kernel.

thorpej 011d4d5f44 Add kernel support for having userland provide the signal trampoline:
* struct sigacts gets a new sigact_sigdesc structure, which has the
  sigaction and the trampoline/version.  Version 0 means "legacy kernel
  provided trampoline".  Other versions are coordinated with machine-
  dependent code in libc.
* sigaction1() grows two more arguments -- the trampoline pointer and
  the trampoline version.
* A new __sigaction_sigtramp() system call is provided to register a
  trampoline along with a signal handler.
* The handler is no longer passed to sensig() functions.  Instead,
  sendsig() looks up the handler by peeking in the sigacts for the
  process getting the signal (since it has to look in there for the
  trampoline anyway).
* Native sendsig() functions now select the appropriate trampoline and
  its arguments based on the trampoline version in the sigacts.

Changes to libc to use the new facility will be checked in later.  Kernel
version not bumped; we will ride the 1.6C bump made recently.

scottr c509ab3f19 Add (unimplemented) cases to handle the 68020 and 68030 to
bus_dmamap_sync().  This corrects a fatal bug on at least some 68030-
based Macs. Closes PR 17180.

thorpej 584c5c23d3 During signal delivery, arrange to have the signal handler invoked
directly, using the trampoline only for the return path.  Saves a
"jsr" in the trampoline.

Reviewed, tested and OK'd by Steve Woodford.

simonb 2d8577fb83 Clean up some rampant code duplication wrt ieee number handling:
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).

briggs c869df6afb The new toolchain wants to generate relocatable branches to globally-defined
symbols--even when the branches are local and would otherwise work with
bxx.b.  Compensate for this by shadowing the relevant labels with local
