there are no pages available immediately to use as a PT page, don't
just roll over and die. Only do that if we're the kernel pmap (shouldn't
happen very ofter [ever?!], and I'm not certain we're guaranteed valid
thread context when operating on the kernel pmap). For user pmaps, wait
for the pagedaemon to wake us up when more free pages are available.
out-dated comments, and other unneeded stuff. This helps prepare
for cleaning up the rest of the code, and adding new functionality.
No functional changes to the kernel code in this commit.
Thanks to Scott for pointing this out to me (I got his mail and figured out
this change before seeing the discussion on tech-kern) and to Charles for
the initial explanation.
while a larger message buffer size might be a good idea (even as the
default), the existing definition here was way too large and was, in
fact, accidental!
- break anon related functions out of uvm_amap.c and put them in their own
file (uvm_anon.c). includes break up uvm_anon_init into an amap and an
an anon init function
- ensure that only functions within the amap module access amap structure
fields (add macros to amap api as needed)
- Don't use tcp_respond(), instead create the tcp/ip header from scratch,
and send it ourself.
- Reuse the mbuf that carried the SYN, or allocate one if that is not
available.
- Cache the route we look up to do the Path MTU Discovery check, and
transfer the reference to that route to the inpcb when the connection
completes.
* Macro'ize a small, but often repeated code fragment.
1. the mask is passed by value, not by reference
2. compare the rest of the mask bits not the valid ones
3. return 0, not the current fd's flags.
Now appletviewer works on an inet display. It will not work
with :0 because /tmp/.X11-pipe/X0 is a named pipe, not a
socket like our /tmp/.X11-unix/X0. Maybe I'll kludge svr4_sys_open
to return an fd to a unix socket when someone attempts to call
open on a unix socket.
- no longer conditionalized
- when traced, charge time to real parent, not debugger
- make it clear for future rototillers that p_estcpu should be moved
to the "copy" region of struct proc.
(Nonaka Kimihiro): grave accent and @ were the wrong way
-assign keysyms to the special japanese conversion keys (even if this
doesn't help wscons - but things must have names)
