684 6739 d 2 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.
 
674 6743 d 6 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
568 6770 d 1 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
534 6773 d 22 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6773 d 22 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6786 d 2 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6793 d 19 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6793 d 22 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
460 6800 d 5 h decky /SPARTAN/trunk/ some fancy stuff  
458 6800 d 5 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6800 d 6 h decky /SPARTAN/trunk/ new build system almost finished  
455 6800 d 18 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
430 6806 d 19 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
422 6813 d 8 h jermar /SPARTAN/trunk/ Move ACPI code to genarch.
Enable it for ia32, amd64 and ia64.
For now, ia64 support is commented out.
 
419 6814 d 21 h bondari /SPARTAN/trunk/arch/ Memory inline functions for AMD64.
memcmp and memcpy are redefined according to norma
 
376 6844 d 1 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
326 6859 d 17 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
309 6863 d 8 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
301 6864 d 5 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
293 6864 d 18 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
289 6864 d 22 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
277 6865 d 20 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
268 6866 d 1 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
265 6866 d 4 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
257 6866 d 8 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.
 
251 6866 d 17 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.
 
242 6867 d 4 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
230 6868 d 2 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
224 6868 d 8 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.

Amd64 prints banner.
 
216 6868 d 18 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
206 6869 d 7 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.

197 6869 d 21 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6869 d 22 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
 
178 6871 d 4 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
