832 6850 d 20 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6851 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).
 
825 6852 d 1 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.
 
808 6854 d 9 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
765 6858 d 21 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
760 6859 d 6 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 6918 d 23 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6918 d 23 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6931 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
391 6979 d 20 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.
 
349 6998 d 21 h jermar /SPARTAN/trunk/ Optimize sorting functions so that malloc() and free() is called only for e_size > EBUFSIZE.
Smaller buffers are allocated directly on the stack.

Some copyright holder fixes on some files written by Ondrej Palkovsky.
 
289 7009 d 23 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
251 7011 d 18 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.
 
226 7013 d 4 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
 
194 7015 d 1 h palkovsky /SPARTAN/trunk/arch/amd64/ Code cleanup.  
188 7015 d 3 h palkovsky /SPARTAN/trunk/arch/amd64/ AMD64 now can switch into long mode.
Basic page tables working.
 
172 7021 d 6 h palkovsky /SPARTAN/trunk/arch/amd64/ Do not allow red area on stack in kernel mode.
Small updates for AMD64 memory layout.
 
169 7024 d 20 h jermar /SPARTAN/trunk/arch/ For each architecture, add an extra type cast of x to __address to both KA2PA() and PA2KA().  
164 7027 d 23 h palkovsky /SPARTAN/trunk/ Basics for amd64 architecture. It does compile, but it does not work yet.
