3880 5577 d 6 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3274 5763 d 11 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.
 
2071 6334 d 6 h jermar /trunk/ (c) versus (C)  
1787 6524 d 8 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1615 6559 d 10 h jermar /kernel/trunk/arch/mips32/src/ mips32 version of alignment-safe memcpy.  
1293 6591 d 11 h palkovsky /kernel/trunk/ Implemented mips memcpy (copy from gcc builtin memcpy).  
1288 6591 d 15 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1096 6637 d 13 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall
 
924 6645 d 18 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
717 6701 d 8 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
534 6743 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6743 d 7 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6755 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
389 6804 d 15 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
341 6826 d 13 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
332 6827 d 14 h palkovsky /SPARTAN/trunk/ Updated symtab so that it works correctly with BE architectures.
Changed compiler for BE MIPS to be mips-sgi-irix5, because
mipsel -EB does not behave correctly.
Doc updates to amd64.
Added ARC BIOS support to MIPS architecture. Putchar works correctly,
kernel passed FPU & some rwlock tests.
 
329 6828 d 9 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6829 d 2 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.
 
319 6831 d 16 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
314 6832 d 3 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6832 d 3 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
205 6838 d 17 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().
 
124 6885 d 6 h decky /SPARTAN/trunk/arch/mips/ fix EXC_Mod define

enhance interrupt handling
 
105 6928 d 3 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.
 
59 6951 d 2 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().
 
50 6953 d 11 h jermar /SPARTAN/trunk/ Big indentation update.

Add Jakub Vana to AUTHORS.

Minor fixes.
 
1 7032 d 9 h jermar /SPARTAN/ Initial import
