684 6716 d 0 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.		  
625 6739 d 23 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.		  
552 6748 d 17 h palkovsky /kernel/trunk/ Named spinlocks  
548 6748 d 20 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6750 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6750 d 20 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)		  
532 6750 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6763 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6763 d 17 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.		  
430 6783 d 17 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
413 6798 d 16 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
391 6811 d 17 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.		  
257 6843 d 5 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.		  
236 6844 d 22 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.		  
227 6845 d 1 h jermar /SPARTAN/trunk/ Add couple of assertions CPU != NULL.

Change type of nrdy from int to count_t.

Rewrite halt() to avoid page fault when CPU == NULL.		  
205 6846 d 5 h jermar /SPARTAN/trunk/ Get rid of memcopy().
All we now have is memcpy() and _memcpy().
memcpy() is defined to be builtin.
Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().		  
198 6846 d 18 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
195 6846 d 20 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.
2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions
3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option		  
168 6856 d 17 h jermar /SPARTAN/trunk/ Add type cast to __address in vm_create().
This seems to fix the problem with userspace.
Looks like KA2PA() returned wrong address when applied on pte_t *.

Uncomment panic() in gp_fault().
Get rid of cli and sti in userspace code.		  
167 6858 d 2 h jermar /SPARTAN/trunk/ Switch over to per vm_t page tables. (breaks ia32 userspace)

Define dummy memcopy() for amd64 and ppc to satisfy compiler.

Get rid of problematic #include <arch/mm/page.h> in mm/page.h.

Indentation fixes and small changes here and there.
