684 6783 d 7 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 6787 d 11 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
655 6802 d 4 h jermar /kernel/trunk/arch/ Compilation fixes.  
627 6807 d 5 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 6807 d 6 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 6812 d 7 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
581 6812 d 10 h palkovsky /kernel/trunk/ Small debug changes.  
577 6812 d 21 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.

Implement functions for reading IMMU and DMMU TLBs.
 
564 6814 d 23 h jermar /kernel/trunk/ Send in some improvements.  
537 6817 d 5 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

534 6818 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6818 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
521 6824 d 10 h vana /kernel/trunk/arch/ia64/ Coding style patch.  
520 6825 d 1 h vana /kernel/trunk/arch/ia64/ Lost files from last commit.  
519 6825 d 1 h vana /kernel/trunk/arch/ia64/ Keyboard support for ski (ia64 emulator)  
501 6830 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
478 6841 d 5 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 6841 d 8 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 6841 d 10 h jermar /SPARTAN/trunk/arch/ia64/ ia64 CPU identification.  
475 6842 d 8 h jermar /SPARTAN/trunk/ Define atomic_t type.  
472 6843 d 8 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 6843 d 21 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 6845 d 7 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix SP_DELTA alignment.
Cosmetics.
 
444 6845 d 7 h vana /SPARTAN/trunk/arch/ia64/ Context restore in HEAVYWEIGHT handlers  
443 6845 d 9 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 6847 d 1 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Begin implemention of heavyweight interrupt handler.
Finish implementation of interval timer.
Add some PAL macros.
 
433 6849 d 0 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 6849 d 2 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add some asm functions for manipulation with PSR, AR and CR registers.
 
431 6849 d 10 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
415 6864 d 9 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 6865 d 13 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 6865 d 23 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.
 
403 6873 d 2 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 6873 d 11 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.
 
391 6879 d 0 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.
 
389 6879 d 11 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
363 6894 d 1 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.  
361 6894 d 2 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
354 6895 d 8 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.
