lukem 4bb41ae2f2 Rework how KERNOBJDIR functions; now it's always determined with
cd ${KERNSRCDIR}/${KERNARCHDIR}/compile && ${PRINTOBJDIR}
This is far simpler than the previous system, and more robust with
objdirs built via BSDOBJDIR.

The previous method of finding KERNOBJDIR when using BSDOBJDIR by
referencing _SRC_TOP_OBJ_ from another directory was extremely
fragile due to the depth first tree walk by <bsd.subdir.mk>, and
the caching of _SRC_TOP_OBJ_ (with MAKEOVERRIDES) which would be
empty on the *first* pass to create fresh objdirs.

This change requires adding sys/arch/*/compile/Makefile to create
the objdir in that directory, and descending into arch/*/compile
from arch/*/Makefile.  Remove the now-unnecessary .keep_me files
whilst here.

Per lengthy discussion with Andrew Brown.

chris a7be705a3c Take the newly added kern.ldscript for handling ELF->a.out from jason, and
apply to the cats kernel build. Seems to work happily for me.

chris 61578bc307 Checkin new interrupt handling code for the footbridge.
This is based upon Jason's work on xscale.

Most of the interrupt handling code is now written in C using an asm stub to
call into the C code.

spl* now only updates a software mask, and does not update the hardware,
this should be much faster.

The new code works well on cats, it's untested on netwinder, but should work.

The code implements generic soft interrupts.

More work is still required to bring the isa interrupt handling code upto
scratch currently all isa interrupts are handled at IPL_BIO on the footbridge.
This may cause isa interrupts to be handled later than they should be.
I plan to fix this in the near future.

jdolecek c82ab2eb79 now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

chris 02debbc8ab Add comment explaining what DDB_KEYCODE does. It should probably be renamed
to DDB_BREAK_CHAR to match the com driver at some point, although even that
isn't used everywhere.

chris aa7f00f3de netwinder and cats can share irqhandler.h, so move (and rename) into the

chris 603917a2c7 Merge isa_machdep.c from netwinder and cats into footbridge/isa (where it
joins other machdep files)
Saves maintaining multiple copies of the same thing, the only differences
were:
IRQ line used on the footbridge (made that a define in include/isa_machdep.h)
name of a dma_ranges variable contained arch name, so just made it generic.

chris cae76053ba Thought I'd checked this in a while back, cats does not need byte_swap.h.
That was me misunderstanding the build system.  (the Makefile change slipped
in as version 1.15)

chris d0879e89ef cats and netwinder can share a common footbridge_intr.h file, so install and
share a common file.

chris 4c5586750b Enable the use of a seperate statclock.
Currently statclock runs at 64hz, maybe it should be faster or slower, I did
try it being the same as hz, but that just made it look like we spent 10% of
time handling interrupts, rather than the 3% that this gives.

Also fix the IPL_LEVELS for netwinder.

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.

thorpej 77a6866508 Enable caching on kernel and user page tables. This saves having
to do uncached memory access during VM operations (which can be
quite expensive on some CPUs).

We currently write-back PTEs as soon as they're modified; there is
some room for optimization (to write them back in larger chunks).
For PTEs in the APTE space (i.e. PTEs for pmaps that describe another
process's address space), PTEs must also be evicted from the cache
complete (PTEs in PTE space will be evicted durint a context switch).

thorpej 5fddbbe3d5 Do cached memory access to L1 tables, making sure to write-back the

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.

thorpej dce4476374 Overhaul how DMA ranges work in the ARM bus_dma implementation.
A new "arm32_dma_range" structure now describes a DMA window, with
a system address base, bus address base, and length.  In addition to
providing info about which memory regions are legal for DMA, the new
structure provides address translation support, as well.

As before, if a tag does not list any ranges, then all addresses are
considered valid, and no DMA address translation is performed.

This allows us to remove a large chunk of code which was duplicated and
tweaked slightly (to do the address translation) from the stock ARM
bus_dma in the XScale IOP and ARM Integrator ports.

Test compiled on all ARM platforms, test booted on Intel IQ80321 and Shark.

thorpej 79af00bddb Move the calls to uvm_page_physload() out of pmap_bootstrap() and
into platform-specific initialization code, giving platform-specific
code control over which free list a given chunk of memory gets put
onto.

Changes are essentially mechanical.  Test compiled for all ARM
platforms, test booted on Intel IQ80321 and Shark.

Discussed some time ago on port-arm.

abs eb73becae2 Ensure all INSTALL config files consistantly include PIPE_SOCKETPAIR,
MALLOC_NOINLINE, and VNODE_OP_NOINLINE. The exceptions are when they
include another config files that already defines the options, or if
they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

chris 5f8eb07bb7 Back out last change, following jason's advice, it's lsof that's actually
broken not the headers.

chris 6052d38107 Allow userland to see machine/vmparam.h. This allows ntop to compile, as it uses the struct uvm from uvm.h, which need the VM_NFREELIST definition.
Of course this does mean that ntop could potentially be platform specific, ie different versions for cats, acorn32 etc as struct uvm maybe a different size, but running on the same cpu architecture.
