684 6737 d 8 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 6741 d 12 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
568 6768 d 7 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
534 6772 d 4 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6772 d 4 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6784 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6792 d 1 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6792 d 4 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 6798 d 10 h decky /SPARTAN/trunk/ some fancy stuff  
458 6798 d 11 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6798 d 11 h decky /SPARTAN/trunk/ new build system almost finished  
455 6798 d 23 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
430 6805 d 1 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
422 6811 d 14 h jermar /SPARTAN/trunk/ Move ACPI code to genarch.
Enable it for ia32, amd64 and ia64.
For now, ia64 support is commented out.
 
419 6813 d 3 h bondari /SPARTAN/trunk/arch/ Memory inline functions for AMD64.
memcmp and memcpy are redefined according to norma
 
376 6842 d 6 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
326 6857 d 22 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 6861 d 13 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
301 6862 d 11 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
293 6863 d 0 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 6863 d 4 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
277 6864 d 2 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
268 6864 d 7 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
265 6864 d 10 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
257 6864 d 13 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 6864 d 23 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 6865 d 9 h palkovsky /SPARTAN/trunk/ Fixed stack settings in boot.S in real mode.
Added ia32 memmap support.
Added cpuid support.
 
230 6866 d 8 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 6866 d 14 h palkovsky /SPARTAN/trunk/arch/ Interrupts for amd64.

Amd64 prints banner.
 
216 6866 d 23 h palkovsky /SPARTAN/trunk/ hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture  
206 6867 d 12 h palkovsky /SPARTAN/trunk/ Better types for ia32 drivers, so that they can be reused in amd64.

197 6868 d 3 h palkovsky /SPARTAN/trunk/ Context-save/restore in AMD64  
195 6868 d 4 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 6869 d 9 h palkovsky /SPARTAN/trunk/arch/amd64/ Fixed linker script to include .eh_frame section.
