2082 6496 d 8 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6501 d 1 h jermar /trunk/ (c) versus (C)  
1851 6650 d 8 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.		  
1850 6653 d 11 h jermar /trunk/kernel/arch/ia64/src/mm/ Indentation and formatting changes.  
1787 6691 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6698 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1735 6714 d 10 h decky /kernel/trunk/ make kernel prints case consistent  
1708 6716 d 10 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6719 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1675 6723 d 8 h jermar /kernel/trunk/arch/ia64/ On ia64, purge DTR entry before overwriting it with new contents.  
1621 6726 d 4 h vana /kernel/trunk/arch/ia64/ itanium faulting task kill  
1411 6739 d 4 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 6758 d 9 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 6770 d 22 h decky /kernel/trunk/ printf-related and other code cleanup  
1210 6772 d 8 h vana /kernel/trunk/ Incomplete VHPT walker support for Itanium  
1104 6802 d 4 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 6807 d 3 h jermar /kernel/trunk/arch/ia64/src/mm/ Fix double page_table_unlock() in ia64 tlb.c.  
1044 6808 d 8 h jermar /kernel/trunk/ Page table locking.  
993 6810 d 1 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 6811 d 1 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 6811 d 11 h vana /kernel/trunk/ Better purge page selection.  
945 6812 d 0 h vana /kernel/trunk/arch/ia64/  
944 6812 d 1 h vana /kernel/trunk/ Itanium tlb_invalidate_pages  
935 6812 d 4 h vana /kernel/trunk/ Two frame stack (standard stack + RSE) on Itanium  
928 6812 d 8 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
919 6815 d 9 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 6823 d 8 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 6823 d 10 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 6824 d 3 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.		  
899 6824 d 4 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.		  
819 6844 d 1 h vana /kernel/trunk/arch/ia64/ TR tlb filling functions  
818 6844 d 4 h vana /kernel/trunk/arch/ia64/ IA-64 TLB filling functions for dynamic tlb filling (TC tlb).  
756 6851 d 21 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.		  
740 6859 d 7 h jermar /kernel/trunk/ ia64 ASID management code (not tested).
