rmind ae7946d0ba - Mention SCHED_M2 in the recent changes; 
- Scheduler works will be in 5.0 release;
- Mention NUMA in the roadmap;

P.S. Everyone: please sync the ROADMAP with the
reality and the works you do.

rmind a21233e46b Import of SCHED_M2 - the implementation of new scheduler, which is based 
on the original approach of SVR4 with some inspirations about balancing
and migration from Solaris.  It implements per-CPU runqueues, provides a
real-time (RT) and time-sharing (TS) queues, ready to support a POSIX
real-time extensions, and also prepared for the support of CPU affinity.

The following lines in the kernel config enables the SCHED_M2:

no options SCHED_4BSD
options SCHED_M2

The scheduler seems to be stable.  Further work will come soon.

martin e9705aba47 Clear the remainder of the status line after updating it - this allows 
messages to be of arbitrary length w/o leaving garbage from previous
ones.

rmind f07012313b mq_receive1: Handle the possible dereference, when cv_timedwait_sig() awakes 
normally (without the error) and MQ_UNLINK is set.
From CID: 4565.

rmind 25e540085b Add cancellation stubs in libpthread for POSIX messages queues and 
asynchronous I/O.

OK by <ad>.

ad 2823fb7428 Defer wakeup() to a soft interrupt, since lptintr() can be called above 
IPL_SCHED.

xtraeme 2e75cc0f7b - Do not allow a 'critical-{max,min}' property in battery 
sensors (those that contain the 'want-percentage' object on its
  dictionary), the 'critical-capacity' prop must be used instead.

- When setting a 'critical-{max,min}' property check if the value is
  higher than the 'max-value' or lower than the 'min-value' on its
  dictionary, raise an error if it's true.

sjg 3a5409e4eb Fix an off-by-one error in handing mal-formed modifiers. 
The issue seems to have been present for some time, only showed up
when running unit-tests on SunOS.
Make sure we get an error message, but otherwise behave as before.

rmind 662df2e4ad - Style, consistency; 
- Replace most panic() checks with KASSERT();
- msgrcv1: Improve readability;
- Remove #ifdef ENOMSG;

No function changes of the interface are intented.
 2007-10-09 03:27:37 +00:00
xtraeme eed1cc9bc8 Fix a typo that prevented a 'critical-capacity' property to 
be added.

mrg 862626dd09 two new hacks: 
- include <stdbool.h> so bool is available _KERNEL for sys/condvar.h
- include <sys/mutex.h> before defining _KERNEL so it won't try to
  include <machine/intr.h> which isn't available to userland.

fixes builds on sparc64.

kernel builds.  Thanks to xtraeme for pointing this out.

sjg e73405e272 Use .MAKE.MAKEFILES to track all the makefiles that have been read 
so they can be used in dependency rules.

skrll c6deb42c81 Provide PTHREAD__ASM_RASOPS for alpha. 
The gcc generated lock try RAS is broken as the store needs to be the last
instruction.
 2007-10-08 16:04:43 +00:00
ad 342d5fc94f Add stubs that provide new soft interrupt API from the vmlocking branch. 
For now these just pass through to the current softintr code.

(The naming is different to allow softint/softintr to co-exist for a while.
I'm hoping that should make it easier to transition.)
