thorpej c0691fd89d Back out previous; it breaks binary compatibility between platforms
in the same MACHINE_ARCH.

gehenna 77a6b82b27 Merge the gehenna-devsw branch into the trunk.
This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

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.

wiz f7a47b635a Remove #ifdef RC7500 defines. 2002-05-02 17:25:31 +00:00
wiz b430d917cf Complete renaming of opms to opms (was mostly pms internally).
Mechanical change, tested by cross-compiling GENERIC from i386.

Approved by christos.

thorpej 110e2a57ff * Change all uses of KERNEL_SPACE_START to KERNEL_BASE.
* Delete now unused KERNEL_SPACE_START.

thorpej 0ba36d6f6f * Rename PROCESS_PAGE_TBLS_BASE -> PTE_BASE
* Rename ALT_PAGE_TBLS_BASE -> APTE_BASE
* Garbage-collect PAGE_TABLE_SPACE_START

chris 1181e367e0 Implement pmap_growkernel for arm32 based ports.
Note that this has been compiled on some systems, cats, IQ80310, IPAQ, netwinder and shark (note that shark's build is currently broken due to other reasons), but only actually run on cats.
Shark doesn't make use of the functionality as I believe there has to be a correlation between OFW and the kernel tables so that calls into OFW work.

simonb 4324f37586 Use "#define<tab>". 2002-02-28 03:17:23 +00:00
christos 6b030ee036 - define other DEV_ constants that the local port uses.
- delete cdev_decl(mm) since <sys/conf.h> does it.

thorpej cd98cbf7fb * For platforms which are already ELF, remove the definition of
MACHINE_ARCH since <arm/param.h> already sets it correctly to "arm".
* For platforms which are not yet ELF, defined MACHINE_ARCH to "arm32"
  if __ELF__ is not defined by the C preprocessor.
* In <arm/param.h>, clarify the rules about when MACHINE and
  MACHINE_ARCH are defined, and to what.  Also, for ELF platforms,
  int the non-_KERNEL case, force both MACHINE and MACHINE_ARCH to "arm",
  rather than allowing platform-specifc code to define either.

kleink 618dddf12f Fix RCS Id. 2002-02-10 09:29:19 +00:00
thorpej 8067595564 Kill arch/arm32. The last platform supported there, Shark, is now
in arch/shark.

(NOTE: arch/dnard, a premature move to split out the Shark support
code, is going to be deleted.  It has bit-rotted.)
