786 6740 d 22 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed
 
762 6744 d 0 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
758 6744 d 15 h jermar /kernel/trunk/arch/ sparc64 bugfix.
When disabling IMMU and DMMU the kernel has to perform synchronization operation
(e.g flush %r or membar #Sync instruction). There is no guarantee that the address
contained in %r is in DTLB and therefore the flush instruction can fault. Normally
this would be recognized and fixed by the OpenFirmware Fast Data MMU fault handler.
However, this handler lives in virtually mapped memory and an attempt to execute
there while the MMUs are disabled would result in a nested trap leading to error state.
Replacing flush %r instruction with membar #Sync, wich is sufficient in this case,
fixes this problem.
 
757 6744 d 18 h jermar /kernel/trunk/ Blacklist addresses between 0xa0000 and 0xfffff on ia64 for frame allocator.
This area contains VGA text frame buffer and should be avoided.
falloc2 test now passes on ia64.
 
756 6745 d 14 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
 
753 6746 d 22 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
 
751 6747 d 0 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6748 d 22 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6749 d 22 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6750 d 16 h jermar /kernel/trunk/ ia64 work.
Add nice wrappers for thash and ttag instructions.
Add nice wrappers for accessing reion registers and PTA.
Fix set_vhpt_environment().
Allocate and initialize page_ht (a.k.a. VHPT).

Add missing header to sparc64.
Remove excessive header from debug.h.
 
746 6751 d 0 h jermar /kernel/trunk/ Page hash table modifications.  
742 6752 d 17 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.
 
740 6753 d 0 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6754 d 21 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
728 6757 d 16 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
726 6757 d 16 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6761 d 20 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6761 d 20 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
684 6768 d 23 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 3 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
659 6786 d 3 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
586 6797 d 22 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
584 6797 d 23 h jermar /kernel/trunk/arch/ia64/src/ski/ Fix IA-64 ski_getchar().
Output operand vs. input operand.
Now the characters are read correctly.
 
583 6797 d 23 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
577 6798 d 13 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
534 6803 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6803 d 19 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 6803 d 19 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.

503 6815 d 22 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).
 
501 6815 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
478 6826 d 21 h jermar /SPARTAN/trunk/ Re-aply mistakenly reverted changes.  
477 6827 d 0 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.
