1968	6416 d 8 h	jermar	/tags/	Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories. The change now should reflect how those releases looked like after checkout.
1965	6416 d 9 h	jermar	/tags/0.2.0.1/	Tagging release 0.2.0.1
906	6655 d 6 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	6676 d 7 h	palkovsky	/kernel/trunk/	Unimportant changes regarding FPU context.
534	6743 d 11 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel again.
532	6743 d 11 h	jermar	/	Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.
501	6755 d 15 h	jermar	/	Rename HelenOS/SPARTAN to HelenOS/kernel.
332	6827 d 18 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	6829 d 6 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	6832 d 21 h	palkovsky	/SPARTAN/trunk/	Added architecture independent hooks for fpu lazy context switching. It is enabled by defining FPU_LAZY
296	6833 d 19 h	palkovsky	/SPARTAN/trunk/	More logical fpu_context_engaged setting. The sse1 test now correctly tests for thread migration settings.
282	6834 d 22 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.
