lukem c5eb4ab601 fix -Wsign-compare issues 2009-01-18 11:56:51 +00:00
pooka d21961207f Include sys/param.h in the kernel to make the vax properly pick up 
memset.  Otherwise vax/macros.h doesn't get included and the usual
lossage ensues.
(I bet you saw that one coming)
 2009-01-14 21:33:22 +00:00
pooka 654753c2e1 include sys/param.h for _HARDKERNEL instead of homegrown def. 2009-01-12 02:53:29 +00:00
pooka 132ffc213b Include userland version of atomic cas routines in librump. 
(the kernel version disables interrupts and therefore can't be used)
 2009-01-10 23:36:22 +00:00
mjf a15a784800 The .if conditional crosses a line boundary, so add a backslash. 
This fixes the kernel build for hppa.
 2009-01-06 13:23:31 +00:00
pooka 1ce853369b Temporarily define MCOUNT as a dummy for _RUMPKERNEL to allow build 
to proceed - the MD macros use processor instructions unavailable
to userspace and should/could be provided as interfaces.
 2009-01-05 18:06:57 +00:00
pooka 69885c98a3 Do not use lockpatches with _RUMPKERNEL (non-PIC ... and pointless). 2009-01-04 18:46:16 +00:00
pooka 58302d6770 Opt for libc versions in case of _KERNEL && !_RUMPKERNEL. 
(kernel version uses sti/cli and is not PIC)
 2009-01-04 18:21:38 +00:00
pooka e77a29de65 allow inclusion of atomic ops in librump 2009-01-04 17:54:29 +00:00
pooka b6e6025d0d Get rid of locks with static initializers using once and atomic ops. 
This makes proplib simplelock-free.

ad 30fd42e845 PR kern/40213 my i386 machine can't boot because of tsc 
- Patch in atomic_cas_64() twice. The first patch is early and makes it
  the MP-atomic version available if we have cmpxchg8b. The second patch
  strips the lock prefix if ncpu==1.

- Fix the i486 atomic_cas_64() to not unconditionally enable interrupts.

christos 2d2593ab23 We don't need this for _STANDALONE, and it needs snprintf to work. 2008-12-17 16:02:27 +00:00
christos cec60a5890 share with kernel; replaces bitmask_snprintf which was very broken: 
- subtracted one from len without checking if len was 0
- checked for a minimum buffer size
- arguments order was inconsistent with other printf like functions
- no way to tell if it overflowed

haad e51aea320a Fix two race conditions in proplib library. In prop_dictionary and prop_number 
there was small window in which was entry left in rb tree with reference
count 0 which lead to rb tree coruption when another thread picked this up
before it was released.
Add 2 new members to the prop_object_t which are used for locking/unlocking
rb tree guard mutex.

Ok by joerg@, core@, thorpej@

from Bernd Ernesti on source-changes@.  This fixes a build breakage
with i386/amd64 bootblocks.

ad c6555ead19 Our qsort() is inappropriate for kernel use because it makes recursive 
calls. Replace it with a kheapsort() function in kernel. Pointed out

haad 185aec71fe Add prop_array_add_int* and prop_array_add_uint* functions. These functions 
can be used to append specified type to the end of prop_array_t.

oster 5577c7fceb Fix build breakage by adding appropriate #includes. 
Patch from joerg@
 2008-08-20 19:58:33 +00:00
joerg 245e086321 Unify the implementation of strto{l,ul,ll,ull,imax,umax,q,uq} into one 
version for signed and one version for unsigned data types.

Add a check for supported bases and set errno (userland) or panic
(kernel, libsa) otherwise.

Make strto{ll,ull,imax,umax} normal symbols and just keep the underscore
versions as strong alias.

Obtained from DragonFly, based on the wide char version from Citrus.

christos ecd6bc7086 typo in comment and white-space fixes mostly from Stathis Kamperis 2008-08-11 05:54:21 +00:00
thorpej 4ce0dc3a15 Fix an issue introduced with the prop_stack change: It's not a good idea to 
return a 3-value enum from a function declared to return bool.  This broke
the recurse case for prop_object_equals().  Instead, declare the object type
equals routine to return a _prop_object_equals_rv_t.

Give the same treatment to the object type free routines: declare them to
return a _prop_object_free_rv_t, and consistently check those return values
againt the enum type.

Tidy up some whitespace while we're here.

dholland 154fe9b1d9 Don't convert cpuid_t through int while testing it for being in range. 
(Might truncate it, for one thing. Also, if the shift result is < 0 the
demons have already flown out of our nose.)

Fixes some -Wsign-compare warnings.

he d6e5879de3 Be consistent in how cpuset_nentries is computed in the kernel and 
in user-land.  This fixes the user-land part.  Now "cpuctl identify 0"
gives a result instead of getting EINVAL from the set-affinity syscall.

rmind 54ccd4a6fa kcpuset_isset: remove if-check. It is not reasonable for kernel, 
saves few cycles, and it is better for CPU cache.
