1702	6529 d 6 h	cejka	/kernel/trunk/	Kernel doxygen comments updated.
906	6631 d 20 h	palkovsky	/kernel/trunk/	Added lazy fpu context allocation. - threads that don't use fpu, don't get allocated fpu context - fpu context alignment on AMD64 nicely disappeared
827	6652 d 21 h	palkovsky	/kernel/trunk/	Unimportant changes regarding FPU context.
534	6720 d 1 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6720 d 1 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6732 d 5 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
332	6804 d 8 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.
326	6805 d 20 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	6809 d 11 h	palkovsky	/SPARTAN/trunk/	Added architecture independent hooks for fpu lazy context switching. It is enabled by defining FPU_LAZY
296	6810 d 9 h	palkovsky	/SPARTAN/trunk/	More logical fpu_context_engaged setting. The sse1 test now correctly tests for thread migration settings.
282	6811 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.
