757 6850 d 2 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 6850 d 23 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.		  
755 6851 d 22 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
754 6851 d 23 h jermar /kernel/trunk/generic/ Remove address space area mapping array.
The information is to be stored directly in page tables.
This is to better support 64-bit systems which can have
fairly large address space areas.		  
753 6852 d 6 h jermar /kernel/trunk/ Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported.		  
752 6852 d 7 h jermar /kernel/trunk/generic/include/ Replace % operator by explicit overflow test to make this ADT compile on ia64.  
751 6852 d 8 h jermar /kernel/trunk/arch/ia64/ Fix initialization of pta.base on ia64.  
750 6853 d 3 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.		  
749 6854 d 6 h jermar /kernel/trunk/arch/ia64/ ia64 virtual address translation subsystem update.  
748 6855 d 6 h jermar /kernel/trunk/arch/ia64/ First HT_HASH_ARCH implementation for ia64.  
747 6856 d 0 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 6856 d 9 h jermar /kernel/trunk/ Page hash table modifications.  
745 6857 d 1 h jermar /kernel/trunk/test/mm/ Fix and cleanup frame allocator tests.
falloc1:
- fix so that it compiles on ia64
- check that frames is not NULL
falloc2:
- threads cannot be passed argument in the way this test did
(otherwise some threads will use the same value for val)
- check that frames is not NULL
- free frames at the end of the test		  
744 6857 d 2 h jermar /kernel/trunk/arch/ia64/ Remove ia64 boot as it is not needed by the simulator.  
743 6858 d 1 h jermar /kernel/trunk/arch/ sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191.		  
742 6858 d 2 h jermar /kernel/trunk/arch/ sparc64 work.
Memory context (ASID) is, in fact, 13 bits (and not 12 bits) wide.		  
741 6858 d 2 h jermar /kernel/trunk/ Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.

Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way.		  
740 6858 d 8 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
736 6860 d 5 h jermar /kernel/trunk/arch/ia64/src/ Fix panic_printf on ia64 to call halt() instead of cpu_halt().  
735 6860 d 6 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator
