557 6757 d 19 h jermar /kernel/trunk/ Add comments describing locking rules for some locks.
Cleanup.
 
552 6758 d 10 h palkovsky /kernel/trunk/ Named spinlocks  
548 6758 d 13 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6760 d 13 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6760 d 13 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 6760 d 13 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6772 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6780 d 13 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 6784 d 18 h jermar /SPARTAN/trunk/ Define atomic_t type.  
458 6786 d 20 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
452 6787 d 12 h decky /SPARTAN/trunk/ major build system revision (unfinished)
this patchset most definitively breaks a lot of things, be patient
 
430 6793 d 10 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
414 6807 d 23 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 6808 d 9 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 6814 d 12 h jermar /SPARTAN/trunk/src/ Fix doxygen comments.  
391 6821 d 10 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 6827 d 19 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 6840 d 11 h jermar /SPARTAN/trunk/src/ Remove _qsort() as its concept is fundamentally broken.

Move lib/the.c to proc/the.c.
 
309 6849 d 22 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
258 6852 d 23 h palkovsky /SPARTAN/trunk/src/proc/ Fixed retyping, so that it compiles with gcc 4.0.2  
248 6853 d 14 h jermar /SPARTAN/trunk/ Make atomic_dec() and atomic_inc() take (volatile int *) argument, not (volatile count_t *).  
241 6854 d 13 h palkovsky /SPARTAN/trunk/ Cleanups so that it compiles on ia-32 & amd-64 cleanly  
227 6854 d 18 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.
 
214 6855 d 10 h vana /SPARTAN/trunk/src/  
213 6855 d 10 h jermar /SPARTAN/trunk/ Add some comments.  
212 6855 d 10 h vana /SPARTAN/trunk/ Basic exception support added for ia64 arch ......  
210 6855 d 11 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
198 6856 d 11 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
195 6856 d 13 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
 
192 6856 d 15 h jermar /SPARTAN/trunk/ Dump implementation of THREAD, TASK and CPU.
Implement preemption-safe versions of THREAD, TASK and CPU using THE.
Get rid of CPU_ID_ARCH on all architectures.

Get rid of cpu_private_data and cpu_private_data_t.
 
184 6856 d 23 h jermar /SPARTAN/trunk/ Add lib/the.c.

Make IA-32's before_thread_runs() use SP_DELTA macro.
 
170 6865 d 10 h jermar /SPARTAN/trunk/ Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread.

Remove two unnecessary cpu_priority_high() calls.
 
167 6867 d 19 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.
 
125 6902 d 10 h jermar /SPARTAN/trunk/ Huge indentation fix.  
118 6931 d 14 h jermar /SPARTAN/trunk/ Replace confusing comment in scheduler.c.

Add warning/explanatory comment to arch.h saying that CPU, THREAD and TASK macros are preemption-unsafe.
 
115 6938 d 9 h jermar /SPARTAN/trunk/ Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file.
Gain both better speed and size.
 
114 6938 d 19 h jermar /SPARTAN/trunk/src/proc/ Fix wrong locking order in scheduler.  
113 6941 d 8 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.
 
111 6941 d 12 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,

Fixed atomic_inc, atomic_dec in mips architecture.
 
109 6944 d 13 h jermar /SPARTAN/trunk/ Discard 'copy' parameter of map_page_to_frame().

Otherwise 'root' is used as page directory address.

Add missing word to new doxygen-style comments in scheduler.c.
