703 6690 d 8 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().		  
576 6724 d 20 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.		  
534 6730 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6730 d 1 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6742 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6756 d 8 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
413 6777 d 21 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 6790 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.		  
309 6819 d 11 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY		  
299 6820 d 8 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Better stack recognition in stack content dump.  
297 6820 d 9 h palkovsky /SPARTAN/trunk/ Symtab now contains variables  
296 6820 d 9 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.		  
286 6821 d 10 h palkovsky /SPARTAN/trunk/arch/amd64/src/ Codingstyle changes  
282 6821 d 12 h palkovsky /SPARTAN/trunk/ Fixed gdtr naming issues after ia32 changes.
Fixed stack alignment on new thread to by multiple of 16,
we are now ABI-correct and we do not #GP on va_arg to boot.
Fixed bad exception register names reporting.
Fixed bad _hardcoded_load_addr, which caused allocation of kernel text
frames.		  
268 6822 d 4 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.		  
226 6824 d 6 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.
