784 6699 d 23 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6699 d 23 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 6700 d 16 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.
 
777 6700 d 19 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
775 6700 d 23 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.
 
762 6702 d 23 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
703 6723 d 0 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().
 
689 6727 d 21 h bondari /kernel/trunk/ Frame alloc test #1  
678 6731 d 16 h decky /kernel/trunk/ move syscall infrastructure to a separate subdir  
675 6732 d 0 h jermar /kernel/trunk/generic/src/ Clean up.  
662 6743 d 15 h decky /kernel/trunk/ initial syscall table support  
650 6747 d 15 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 6751 d 16 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
625 6751 d 21 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.
 
624 6751 d 22 h jermar /kernel/trunk/generic/ Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists.  
623 6752 d 3 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.
 
557 6760 d 0 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
552 6760 d 15 h palkovsky /kernel/trunk/ Named spinlocks  
548 6760 d 18 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6762 d 18 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6762 d 18 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6762 d 18 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6774 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6782 d 18 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 6786 d 23 h jermar /SPARTAN/trunk/ Define atomic_t type.  
458 6789 d 1 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6789 d 17 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
430 6795 d 15 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6810 d 4 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
 
413 6810 d 14 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
404 6816 d 17 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
391 6823 d 15 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
378 6830 d 0 h jermar /SPARTAN/trunk/ Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations.

Reorganize #include's in scheduler.c.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.
 
350 6842 d 16 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.
 
309 6852 d 3 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
258 6855 d 3 h palkovsky /SPARTAN/trunk/src/proc/ Fixed retyping, so that it compiles with gcc 4.0.2  
248 6855 d 19 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
241 6856 d 18 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
227 6856 d 23 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.
