788 6843 d 5 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6843 d 6 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.
 
785 6843 d 9 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6843 d 9 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6843 d 10 h palkovsky /kernel/trunk/generic/ Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/
 
779 6844 d 2 h jermar /kernel/trunk/generic/ Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems.
 
775 6844 d 10 h palkovsky /kernel/trunk/generic/ Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.
 
703 6866 d 10 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
675 6875 d 10 h jermar /kernel/trunk/generic/src/ Clean up.  
650 6891 d 1 h jermar /kernel/trunk/ sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7.
 
631 6895 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
625 6895 d 7 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
557 6903 d 10 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
534 6906 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6906 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6918 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6926 d 4 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
475 6930 d 10 h jermar /SPARTAN/trunk/ Define atomic_t type.  
458 6932 d 11 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6933 d 3 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
