967 6821 d 0 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
832 6852 d 12 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6852 d 18 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).		  
825 6853 d 17 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.		  
765 6860 d 13 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
760 6860 d 22 h jermar /kernel/trunk/ mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.

Remove GET_PTL0_ADDRESS from kernel.

Update sparc64 comments in barrier.h.		  
534 6920 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6920 d 15 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6932 d 19 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
403 6975 d 14 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
394 6980 d 13 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 6981 d 12 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.		  
341 7003 d 21 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
319 7009 d 0 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
306 7010 d 2 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.		  
177 7017 d 22 h jermar /SPARTAN/trunk/ Add some comments to IA-32 src/boot/boot.S and src/smp.S.

Make the boot stack start on page boundary.
This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
Non IA-32 macros are dummy.

Reduction of many #include paths.		  
169 7026 d 12 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
135 7057 d 20 h jermar /SPARTAN/trunk/ Fix setters of page table attributes for both IA-32 and MIPS.  
125 7062 d 12 h jermar /SPARTAN/trunk/ Huge indentation fix.  
121 7063 d 12 h jermar /SPARTAN/trunk/ Begin MIPS implementation of 4-level page table interface.

Add email address to each item in doc/AUTHORS.

Correct type names in comments in mm/vm.c.
Introduce ptl0 pointer in vm_t.
