b5f53318b6 /rescue/*, and a new crunchgen to ensure /rescue/* is statically linked 2002-08-24 13:25:01 +00:00
lukem
9aa0322535 don't bother with "rm -f $$t" before ${INSTALL_LINK} or ${INSTALL_SYMLINK}, 
as they default to using install(1) -r.
the rm can cause problems in certain situations, such as moving a library or
shared linker that install(1) depends upon to another location and replacing
it with a (sym)link.

70b5675025 Assembly version of ffs(3). 
Confirmed to return the same value as that of the C version.

The results of a simple benchmark on SH-4 200MHz, is shown below.
I think this shows acceptable performance.

return value	C version	this version	speed

ffdedb6d80 In pmap_map_in_l1() and pmap_unmap_in_l1(), make sure that the VA 
that is passed in is already aligned to a 4M super-section.

d158b3a37a When we allocate a PTP, make sure the offset we specify is for 
the 4M super-section that the PTP will map, not some random 1M
chunk of it.  This gives the PTP hint code a much better chance
to working properly, and allows us to tidy up the code that
flushes a PTP from the cache in pmap_destroy().
 2002-08-24 02:50:53 +00:00

aafe6e006c Define macros describing the 4M super-sections that our pmap 
actually uses (since we allocate PT pages in 4K chunks, rather
than 1K chunks).

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).

9f3703ab9a - use _PATH_ALTSHELL (which defaults to _PATH_BSHELL) as the default ALTSHELL 
(as opposed to _PATH_BSHELL), to allow the ALTSHELL to be changed.

a71473b576 Add autoconfiguration glue for the Sun4d "cpu-unit". Each processor 
board has 2 CPU units (one for each processor), one of which also has
a "bootbus", to which the serial ports, etc. are attached.

We can now probe/attach CPUs on a SPARCserver 1000.

the cpu driver.

G/C a couple of other unused devices.

As a precaution, comment out the wscons entries until
the kernel supports it and note that their major numbers
will need to be re-synced.

9ba60b4297 Install the ECC error interrupt handler at the level specified by 
a "4xx-ecc-irq" property.
If the property isn't defined, assume the hardware has no ECC support.
This should, ideally, be a config file option.

a625cf764a Don't create satlink or ttyE device nodes. The former clashed with tty00,
