69abdbf60c Undo a misguided previous change to the pmap_update() API. 2001-04-22 23:19:26 +00:00
thorpej
5871b80f00 Use uvm_pageboot_alloc() for early memory allocation, rather than 
calling pmap_steal_memory() directly.  On these platforms, since
uvm_pageboot_alloc() is a wrapper around pmap_steal_memory(), there
is no functional change.  This is merely for API consistency.

cfb5c7ed9f Make pmap_virtual_space() a required pmap function, even on platforms 
which have pmap_steal_memory().  This is to reduce the API differences
between pmaps that implement pmap_steal_memory() and pmaps which do
not.

Note that pmap_steal_memory() needs to adjust *vstartp and/or
*vendp only if it used addresses within the range provided to UVM
via the pmap_virtual_space() call.  I.e. it is not necessary to do
so in any current pmap_steal_memory() implementation.

4738622712 Give pmap_update() an argument (a pmap_t) so that it knows which 
pmap it should be updating.

7f10ba88b1 #define away pmap_update() in <machine/pmap.h> so that no function 
call overhead is incurred as we start sprinkling pmap_update() calls
throughout the source tree (no pmaps currently defer operations, but
we are adding the infrastructure to allow them to do so).

virtual space.  the latter isn't initialized yet when the value is needed.

ac3bc537bd eliminate the KERN_* error codes in favor of the traditional E* codes. 
the mapping is:

KERN_SUCCESS			0
KERN_INVALID_ADDRESS		EFAULT
KERN_PROTECTION_FAILURE		EACCES
KERN_NO_SPACE			ENOMEM
KERN_INVALID_ARGUMENT		EINVAL
KERN_FAILURE			various, mostly turn into KASSERTs
KERN_RESOURCE_SHORTAGE		ENOMEM
KERN_NOT_RECEIVER		<unused>
KERN_NO_ACCESS			<unused>
KERN_PAGES_LOCKED		<unused>

fb20946774 keep V0 value (system call number) and restore it in exception frame, 
when error is ERESTART. otherwise, user process will re-issue syscall
with broken system call number and get SIGSYS signal and terminate.

patch made by Jason R Thorpe <thorpej@zembu.com>. tested by me.

8b24036797 Require the machine-dependant DDB commands to be in db_machine_command_table[] 
and link it directly to db_command_table[] so that it's not necessary
to do this at runtime. Make db_machine_command_table[] const on all ports.
g/c now unneded stuff, like db_machine_commands_install(), db_machine_init()

9f5a22b3ee New syscall entry implementation based on the Alpha version 
as hacked by mycroft.
- Use syscall_intern() to give a process a plain or fancy
  syscall based on ktrace flags.
- Avoid copying from the trapframe into a local array as much
  as possible.

Yields roughly 5% improvement on a 25MHz R3000 (DECstation 5000/200)
on a simple syscall benchmark.

There's still some work that can be done using __HAVE_MINIMAL_EMUL.

fd0ca62926 Put signal posting back in userret() for now; for it to work 
properly, we need to make astpending a per-process variable.

1eb36d23fd - Make ast() loop around astpending; it's possible for a new 
AST to be posted when delivering signals, or after a process
  is preempted.
- Move all signal posting to ast().  userret() is now a one-liner.

19adf5c987 Make userret() "static __inline". This lets it be inlined, even if you 
do not have the compiler inline normal functions to save space.  It helps
a bit on lmbench.
