830 6816 d 21 h jermar /kernel/trunk/ Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().
 
823 6818 d 11 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
819 6818 d 14 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6818 d 17 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
816 6818 d 21 h jermar /kernel/trunk/ Fix mapping1 test.

Cleanup.
 
815 6818 d 22 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
813 6819 d 11 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.
 
793 6820 d 20 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.
 
792 6820 d 20 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
786 6821 d 19 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 6824 d 21 h palkovsky /kernel/trunk/ Currently not-working SLAB allocator.
- slightly changed interface to frame_alloc, allow zone preference
 
758 6825 d 12 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 6825 d 14 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 6826 d 11 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 6827 d 18 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.
 
751 6827 d 20 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
749 6829 d 18 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6830 d 18 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6831 d 12 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 6831 d 21 h jermar /kernel/trunk/ Page hash table modifications.  
742 6833 d 14 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.
 
740 6833 d 20 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6835 d 17 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
728 6838 d 12 h vana /kernel/trunk/arch/ia64/src/mm/ Serialize writes to RR because of assembler RAW warning.  
726 6838 d 13 h jermar /kernel/trunk/arch/ia64/src/mm/ Temporarily disable set_VHPT_environment() to stop ia64 kernel from faulting.  
716 6842 d 16 h vana /kernel/trunk/arch/ia64/src/mm/ ttag and thash envelope functions  
715 6842 d 17 h vana /kernel/trunk/arch/ia64/ VHPT setup to be able to use ttag and thash instructions  
684 6849 d 20 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 6853 d 23 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
659 6867 d 0 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
586 6878 d 19 h jermar /kernel/trunk/ Fix ppc32 and sparc64 to compile again.
Fix sparc64 to function again.
 
584 6878 d 19 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 6878 d 20 h jermar /kernel/trunk/arch/ia64/ Fix IA-64 so that it compiles again.
Characters are not recognised correctly.
 
577 6879 d 9 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
534 6884 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6884 d 15 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 6884 d 15 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
523 6890 d 19 h jermar /kernel/trunk/ Clean up.  
522 6890 d 22 h vana /kernel/trunk/arch/ia64/src/ski/ Comment update  
521 6890 d 22 h vana /kernel/trunk/arch/ia64/ Coding style patch.
