1787 6578 d 17 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1289 6645 d 21 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1191 6667 d 2 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1185 6667 d 20 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1171 6669 d 2 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1106 6689 d 13 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1072 6694 d 23 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1004 6697 d 10 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
938 6699 d 17 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
894 6712 d 18 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
803 6733 d 11 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
778 6735 d 16 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.
 
756 6739 d 11 h jermar /kernel/trunk/ Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory.
 
694 6762 d 17 h decky /kernel/trunk/arch/amd64/ break AMD64, will be fixed soon  
684 6762 d 20 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 6766 d 23 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
568 6793 d 19 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
534 6797 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6797 d 16 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6809 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
486 6817 d 12 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
483 6817 d 15 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 6823 d 22 h decky /SPARTAN/trunk/ some fancy stuff  
458 6823 d 23 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6823 d 23 h decky /SPARTAN/trunk/ new build system almost finished  
455 6824 d 11 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
430 6830 d 13 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
422 6837 d 2 h jermar /SPARTAN/trunk/ Move ACPI code to genarch.
Enable it for ia32, amd64 and ia64.
For now, ia64 support is commented out.
 
419 6838 d 15 h bondari /SPARTAN/trunk/arch/ Memory inline functions for AMD64.
memcmp and memcpy are redefined according to norma
 
376 6867 d 18 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
326 6883 d 10 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 6887 d 1 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
301 6887 d 22 h palkovsky /SPARTAN/trunk/arch/ Backported amd64 build process back to ia32.  
293 6888 d 11 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 6888 d 15 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
277 6889 d 14 h palkovsky /SPARTAN/trunk/arch/ Reverted APIC mapping back to identity mapping.
Added AMD64 SMP support. Works now!
 
268 6889 d 18 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
265 6889 d 22 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
257 6890 d 1 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 6890 d 11 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.
