ross cf1ca54803 Minor Tsunami-related changes. 1999-06-29 07:22:25 +00:00
ross 10f1f2d81f Prototype dot_conv(), new routine in machdep.c that formats an alpha
long like this: e081.8000.8000.0004

I'll do what I can to make new ones soon.  8-)

thorpej 5dec34efed The kernel pmap can be accessed (and locked!) while in an interrupt
context, so we must block interrupts which may cause memory allocation
before asserting the kernel pmap's lock.  Put this all in PMAP_LOCK()
and PMAP_UNLOCK() macros to make it easier.

thorpej c1eb28c237 Make the list of all pmaps LRU-ordered, and update a comment regarding
locking.

thorpej 2102d5a17e Save ourselves some work in some pv list traversal functions; keep a pointer
to the PTE that maps the page in the pv_entry so that we don't have to
compute it from the pmap/va.
1999-05-23 17:49:07 +00:00
thorpej 66324de865 Use the pool allocator for pv_entry structures. Set a (patchable/config'able)
low water mark on the pool, so we have some chance of crawling along in
extreme memory shortages.

christos c596c324e3 Define __builtin_*() for lint 1999-05-03 16:30:31 +00:00
ross c5a82dd848 * New MI man page for fp{set,get}{round,sticky,mask}(3).
* Implement fpgetsticky() for alpha.
* Direct fpsetsticky() and fp{get,set}mask() into alpha kernel via sysarch(2).
* Define new sysarch(2) stub for above and install and distribute sysarch.h
for alpha.  (The fpcr IS user mode r/w, but for reasons beyond the scope
of a commit message kernel calls are needed.) And much kernel Magick is
required before these do anything, but this way programs compiled under
1.4 will DTRT on future snapshots and releases.

to the instruction _after_ the `call_pal bpt' instruction.

thorpej e468d4c8d9 Fix a bug in TBI optimization uncovered by the "access_type" changes. Thanks
to Bernd Ernesti for providing crash dumps to Charles Hannum who tracked
it down.

cgd 7a2f0695dd clean up slightly, do a little #define trick to make checksumming
the boot block a little easier/more 'clean', and provide a macro to
checksum the boot block.

cgd 5d472dba93 define 'struct boot_block' which is the alpha (SRM) boot block 1999-04-02 07:32:33 +00:00
thorpej 567cda0537 Don't bother allocating mb_map on these systems. Mbuf clusters are
allocated from a pool, and the MIPS and Alpha use KSEG to map pool
pages.  So, mb_map wasn't actually being used.  Saves around 4MB of
kernel virtual address space in a typical configuration.

Garbage-collect the related VM_MBUF_SIZE constant.
1999-03-26 00:15:04 +00:00
drochner 76fa1751fe Add a macro to check for sufficient pointer alignment in bus.h context,
"BUS_SPACE_ALIGNED_POINTER()".
Equal to the param.h "ALIGNED_POINTER()" normally, but obeys additional
requirements of the bus_space_xxx_n() macros. (BUS_SPACE_DEBUG)

mjacob 7c785b8a35 Well, sizeof needs to be printed with a %lu- I guess not many people build
debug kernels!

thorpej 4cdbd84b63 First-cut at multiprocessor TLB shootdown. This simple implementation can
probably be improved somewhat, but an attempt to be efficient has been
made.

Note: TLB shootdowns are NOT YET ENABLED.
1999-02-24 19:22:16 +00:00
thorpej 911465b54c Restructure the IPI code a little, allowing multiple IPIs to be sent at
once.  Add a way to broadcast an IPI to all processors (except the sender,
obviously).  Add an IPI for TLB shootdown.
1999-02-24 19:17:09 +00:00
thorpej 76e4555f2c Now that we have the kthread mechanism, massively clean up the way
additional processors are spun up on multiprocessor Alpha systems.
Now, each processor gets its own idle thread (the primary processor
uses proc0).  This idle thread is used in switch_exit(), rather than
explicitly referencing proc0.

Also, make `curproc', `fpcurproc', and `curpcb' per-cpu values.  This
required some data structure rearrangement; cpu info is now statically
allocated in the BSS, rather than via malloc(), and cpu_softc is gone.
(Modeled somewhat after NetBSD/sparc's multiprocessor info structures.)

bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

ross 8470625657 New module to hold the alpha-specific prototypes that don't need to be
exported to the MI kernel. Almost everything here was formerly in cpu.h.
Optionally, this module could in the future be used to #include anything
that is always needed by arch/alpha modules.
1998-11-19 01:57:56 +00:00
ross 19a4c3110c Rip out 70 lines of (all of) the port-alpha-specific decls and prototypes.
They should not be visible to the MI kernel and the MI kernel shouldn't
depend on this junk.  Most of it moves to new module <machine/alpha.h>.

Leave badaddr() here, though, because it's used so widely.

ross e2e3ee52ae Nuke the giant ugly-as-sin per-platform INTRNAMES masterpiece.
I just cannot add one more platform without getting sick.
Instead, we do just one table for all platforms. More-or-less,
it was only the A12 that even named it's individual interrupts anyway.

Also, prototype set_iointr() here. It's a slightly odd place, but 10*
better than the old place it was, and this file is included by exactly
the perfect set of .c files for set_iointr() visibility.

thorpej 49c62c4336 Changes to support fork_kthread():
- cpu_set_kpc() now takes void *arg third argument, passed to the
  entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
  When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.
