2bc5adb20e Instead of checking vm_physmem[<physseg>].pgs to determine if 
uvm_page_init() has completed, add a boolean uvm.page_init_done,
and test against that.  Use this same boolean (rather than
pmap_initialized) in pmap_growkernel() to determine if we are
being called via uvm_page_init() to grow the kernel address space.

This fixes a problem on some i386 configurations where pmap_init()
itself was needing to have the kernel page table grown, and since
pmap_initialized was not yet set to TRUE, pmap_growkernel() was
choosing the wrong code path.

Fix tested by Havard Eidnes.

230876cf26 Merge parts of chs-ubc2 into the trunk: 
* Remove the casts to vaddr_t from the round_page() and trunc_page() macros to
  make them type-generic, which is necessary i.e. to operate on file offsets
  without truncating them.
* In due course, cast pointer arguments to these macros to an appropriate
  integral type (paddr_t, vaddr_t).

Originally done by Chuck Silvers, updated by myself.

4ad898818b Fallout from callout. 2000-03-24 01:04:11 +00:00
thorpej
b667a5a357 New callout mechanism with two major improvements over the old 
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

908f6bc4cd Infrastructure for lazy istream sync in the pmap module:

d5e85e61cf Fixes PR#8836. Some changes made by somebody else were a tad incomplete so 
configuring w/o SIO broke compilation. I forget why, but there was at one
point (and may still be) a dependency between SIO and EISA. This change
just makes things compile sensibly again. It may make no sense to build
a kernel w/o sio in this case. I can't test this conveniently because I
haven't got a 4100 with a video card in it at the moment.

0aa48d5c55 New delay(), more carefully coded: 
- Use explicit assembly; don't want the compiler optimizing things too
  much here.
- Subtract 2 for each iteration of the loop, rather than 3.  The loop
  consists of only 2 instructions (even the C version compiled to a
  loop of 2 instructions).

The latter change has squashed a fairly annoying timing bug in the
mii_bitbang module as used by the `ex' driver on my AlphaStation 500.

XXX delay() should maybe be rewritten again, to use the rpcc instruction.

89ae0bf93c Inline several things from pal.s: 
- alpha_rpcc(), alpha_mb(), alpha_wmb() -- these are instructions, and
  we win by inlining them: rpcc is generally used for profiling, and
  the memory barriers really should execute as quickly as possible with
  minimal side-effects (like additional loads/stores required to call the
  functions!)
- alpha_pal_imb(), alpha_pal_rdps(), alpha_pal_swpipl(), alpha_pal_tbi(),
  alpha_pal_whami() -- these are PALcode ops.  We must specify some register
  clobbers for these.

We have a very decent size savings as a result.  My test system:
text    data    bss     dec     hex     filename
2671724 235848  377016  3284588 321e6c  /netbsd.bak
2617708 235736  377016  3230460 314afc  /netbsd

Most of this comes from fewer register saves/restores around spl*() calls
(now that alpha_pal_rdps() and alpha_pal_swpipl() are inlined).

Note that alpha_pal_rdps() and alpha_pal_swpipl() remain in pal.s to
maintain binary compatibility with LKMs that may use spl*() functions.

94552ad5d6 - Use alpha_atomic_{add,sub}_q() to update the pmap statistics. We now no 
longer need to lock the kernel pmap in pmap_kenter_pa() and pmap_kremove().
- Since locking the kernel pmap in interrupt context is no longer required,
  don't go to splimp() when locking the kernel pmap.
- Implement a new pmap_remove() function, not yet enabled by default.  It
  is structured like pmap_protect, and should be *much* faster.  This was
  actually written quite some time ago, but never committed because it
  didn't work properly.  Given the recent bugfix to pmap_protect(), "duh,
  of course it didn't work properly before...".  It seems to work fine now
  (have done several builds and run the UVM regression tests using the new
  code), but it is currently run-time optional so that some performance
  measurements can be easily run against the old and new code.

fd6f19b057 Correct the clock speed setting: the GPI2 bit is only for the Alpha baseboard 
TCDS;  the TC option card has it's own clock.

Also don't use the TCDSF_FASTSCSI flag to clear fast mode - just rely on the
PROM environment.

add81fb25a New -s option. Arranges for the 64-bit alpha checksum to contain within it 
an embedded 16-bit sparc checksum and 16-bit sparc magic number.

9ff31ad0f5 New option: -s 
.
Makes the 64-bit alpha checksum magically contain an embedded 16-bit
Sun (NetBSD/sparc) compatible magic number and checksum. This is the
last piece in the "boot one disk from alpha, sun, and i386" problem.
.
And for those who told me this had been done before, :-P.  It turns out,
it was only done in the collective sense by multi-disk distributions.
