1780 6503 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1769 6505 d 22 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.		  
1702 6524 d 6 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
958 6616 d 0 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.		  
852 6639 d 5 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
849 6639 d 23 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
831 6647 d 4 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).		  
600 6708 d 5 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.		  
599 6708 d 6 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
594 6709 d 1 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
534 6715 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6715 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6727 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
403 6770 d 0 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6772 d 21 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).		  
396 6774 d 7 h jermar /SPARTAN/trunk/ Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)		  
394 6774 d 23 h jermar /SPARTAN/trunk/arch/mips32/ MIPS32 memory management work.
Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14).
Introduce two new bits in pte_t (i.e. 'a' and 'w').
Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)		  
391 6775 d 22 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.		  
389 6776 d 9 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().		  
341 6798 d 6 h jermar /SPARTAN/trunk/ Rename mips port to mips32.
