1675 6730 d 1 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6732 d 21 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1411 6745 d 21 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1288 6765 d 2 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.		  
1221 6777 d 15 h decky /kernel/trunk/ printf-related and other code cleanup  
1210 6779 d 1 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1104 6808 d 21 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1080 6813 d 20 h jermar /kernel/trunk/arch/ia64/src/mm/ Fix double page_table_unlock() in ia64 tlb.c.  
1044 6815 d 1 h jermar /kernel/trunk/ Page table locking.  
993 6816 d 18 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.		  
958 6817 d 18 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
947 6818 d 4 h vana /kernel/trunk/ Better purge page selection.  
945 6818 d 17 h vana /kernel/trunk/arch/ia64/  
944 6818 d 17 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
935 6818 d 21 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
928 6819 d 1 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
919 6822 d 1 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.		  
902 6830 d 1 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
901 6830 d 3 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
900 6830 d 20 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Proper TLB fault handlers' headers and prototypes.
PFN 0 needs no longer be marked unavailable to frame allocator.
