749de7f2a4 Since _file is a short, check that the fd fits in it, otherwise bail with 
EMFILE. We treat _file as an unsigned short to double our range, with a
special case for -1 (closed). Make a note of what we should do about stdio
if we ever bump libc. We could change _file in the future compatibly to an
int by putting it in the extension space but for now we don't bother.

04973f7441 When reading a request from the kernel, only allocate as much memory 
as needed to read a request instead of the maximum message size.
Insanely enough, this makes "cheap backend I/O" file systems such
dtfs and sysctlfs perform 10-30% better (depending on the average
size of incoming requests).

7c2ddc1d53 Bump version for lazy contexts (probably not necessary, but it's

 2008-01-28 18:42:09 +00:00
pooka
d1d05d65b9 Implement lazy contexts for file systems using puffs_mainloop(). 
Previously each request was executed on its own callcontext and
switched to every time the request was being processed.  Now requests
borrow the mainloop context and switch only if/when they yield.
This takes two context switches away from a file system request
bringing down the typical amounts 2->0 (e.g. dtfs) and 4->2 (e.g.
psshfs).

The interfaces for manually executing requests changed a bit:
puffs_dispatch_create() and puffs_dispatch_exec() must now be used.
They are not tested, as nothing in-tree wants them and I doubt
anyone else is really interested in them either.

Also do some misc code cleanup related to execution contexts.  The
"work-in-progress checkpoint" committed over a year ago was starting
to look slightly weed-infested.

b5e9addd22 sched_setparam: fix the case when incorrect (according to the class)

Minor fixes for scheduling calls to conform the POSIX:
- If pid is equal to zero, use the calling process;
- In case of permission problem, return EPERM instead of EACESS;
- sched_setscheduler() should return previously used policy;
- pthread_* calls should return the error code or zero;

- Move cpuset_t defintion from pset.h to sched.h;
- Remove the #include of pset.h in pthread.h;

1717a7fe75 Add address translation support for 4MB pages, which we use to map the 
kernel text.

324e44d74f The address translation routine needs to use the plN_pi macros (for 
indexing into the PTP), not the plN_i ones (for indexing into the entire
linear page table); cf. the analogous code for amd64.  Fixes ~everything
to do with kernel core dumps on i386.

636e495315 Provide some transparent "support" for "distributed" file systems. 
If the env variable PUFFS_COMFD is set, the descriptor value
contained in it is used for communication instead of opening
/dev/puffs and doing mount(2).

This feature is obviously very undocumented and should not be used
without adult supervision.

989565f81d - Fix pthread_rwlock_trywrlock() which was broken. 
- Add new functions: pthread_mutex_held_np, mutex_owner_np, rwlock_held_np,
  rwlock_wrheld_np, rwlock_rdheld_np. These match the kernel's locking
  primitives and can be used when porting kernel code to userspace.

- Always create LWPs detached. Do join/exit sync mostly in userland. When
  looped on a dual core box this seems ~30% quicker than using lwp_wait().
  Reduce number of lock acquire/release ops during thread exit.
