1780 6749 d 0 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1776 6749 d 3 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1735 6765 d 7 h decky /kernel/trunk/ make kernel prints case consistent  
1702 6770 d 3 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1595 6777 d 10 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1411 6790 d 1 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 6809 d 6 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.
 
1196 6828 d 4 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1044 6859 d 5 h jermar /kernel/trunk/ Page table locking.  
983 6861 d 2 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
958 6861 d 22 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.
 
831 6893 d 2 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
 
830 6893 d 4 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().
 
765 6900 d 20 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6901 d 1 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
756 6902 d 18 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 6903 d 17 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.
 
730 6913 d 0 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6914 d 19 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
704 6921 d 1 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.
