691 6769 d 0 h jermar /kernel/trunk/arch/ Cleanup.  
684 6769 d 1 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
674 6773 d 5 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6787 d 22 h jermar /kernel/trunk/arch/ Compilation fixes.  
627 6792 d 23 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.
 
625 6793 d 0 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.
 
583 6798 d 1 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.

Implement functions for reading IMMU and DMMU TLBs.
 
564 6800 d 17 h jermar /kernel/trunk/ Send in some improvements.  
537 6802 d 23 h jermar /kernel/trunk/ Buddy system cleanup and fixes.
- missing use of KA2PA in frame_init
- truncating black list addresses to frame boundaries
- removal of left-over obsolete structures
- fixing some comments
 
534 6803 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6803 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
521 6810 d 4 h vana /kernel/trunk/arch/ia64/ Coding style patch.  
520 6810 d 19 h vana /kernel/trunk/arch/ia64/ Lost files from last commit.  
519 6810 d 19 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6816 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
478 6826 d 23 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 6827 d 2 h vana /SPARTAN/trunk/ Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable.  
476 6827 d 4 h jermar /SPARTAN/trunk/arch/ia64/ ia64 CPU identification.  
475 6828 d 2 h jermar /SPARTAN/trunk/ Define atomic_t type.  
472 6829 d 2 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
470 6829 d 15 h jermar /SPARTAN/trunk/ ia64 work.
Big cleanup of IA-64 interrupt processing.
Merge of interrupt.c and interrupt_handler.c.
Rewrite of ivt.S and interrupt.c.
Higher level interrupt handlers are now passed a vector number and a pointer to stack structure.

ia32 work.
ia32 has ordered writes. Until it deploys weaker memory ordering model, write_barrier() can be empty statement.
 
445 6831 d 1 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix SP_DELTA alignment.
Cosmetics.
 
444 6831 d 1 h vana /SPARTAN/trunk/arch/ia64/ Context restore in HEAVYWEIGHT handlers  
443 6831 d 2 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.
 
435 6832 d 19 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
 
433 6834 d 18 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix definition of __u32.
Add more register manipulation functions.
Add unions describing bit-structured registers.
Distinguish between timer, unhandled and spurious external interrupts.
Initialize interval timer to generate first timer interrupt.
 
432 6834 d 20 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.
 
431 6835 d 4 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
415 6850 d 3 h jermar /SPARTAN/trunk/arch/ia64/include/ Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow.  
414 6851 d 7 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 6851 d 17 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).
