354 6905 d 4 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.
 
353 6905 d 9 h bondari /SPARTAN/trunk/arch/ia32/ Outb, outw, outl are now inline functions  
352 6905 d 21 h bondari /SPARTAN/trunk/arch/ia32/ outb inline function  
349 6907 d 22 h jermar /SPARTAN/trunk/ Optimize sorting functions so that malloc() and free() is called only for e_size > EBUFSIZE.
Smaller buffers are allocated directly on the stack.

Some copyright holder fixes on some files written by Ondrej Palkovsky.
 
348 6909 d 21 h jermar /SPARTAN/trunk/arch/ Optimize some assembler functions.  
347 6909 d 23 h jermar /SPARTAN/trunk/ Documentation updates for amd64, mips32 and ia32.

Replace %L with %P printf() formatter in MPS and ACPI detection functions to print addresses in maximal width.

Tweak memmap.S and IA-32 and AMd64 boot.S.
Cancel unneeded instructions.
Replace cmpl $0, %ebx with testl %ebx, %ebx.
Move memmap.S data to K_DATA_START section.
 
345 6910 d 22 h palkovsky /SPARTAN/trunk/arch/mips32/include/  
344 6910 d 22 h palkovsky /SPARTAN/trunk/ Added more code to arc.
Fixed bad name in byteorder.h
 
343 6911 d 5 h jermar /SPARTAN/trunk/ Finish renaming of mips and ppc ports.  
342 6911 d 5 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.  
341 6911 d 5 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
339 6912 d 3 h palkovsky /SPARTAN/trunk/arch/mips/ Make the objcopy files compatibile with gnu-sgi-irix linker.  
338 6912 d 3 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
337 6912 d 5 h jermar /SPARTAN/trunk/arch/ia32/ Uncomment LONG(0xdeadbeaf) in IA-32 linker script so that the kernel is linked correctly.  
334 6912 d 5 h jermar /SPARTAN/trunk/arch/ Cleanup.
Cancel __fake in pm.c and replace it with LONG(0xdeadbeaf) in linker script. Still need some to find out why it must be there.
Remove comment saying, that mips is little-endian.
 
332 6912 d 6 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.
 
331 6912 d 6 h bondari /SPARTAN/trunk/ Generic quicksort and bubble sort implementation.
ACPI MADT parser now uses qsort() for index sorting
 
330 6913 d 1 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad address loading in simulators.
FPU cooprocessor unusable now checks, if it is FPU that is unusable.
 
329 6913 d 1 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
328 6913 d 7 h jermar /SPARTAN/trunk/ IA-32 can be now cross-compiled by ./build.ia32 cross.
Unify IA-32 Makefile.inc and Makefile.inc.cross.

Update doc/requirements.

Small changes elsewere.
 
327 6913 d 17 h palkovsky /SPARTAN/trunk/ Doc updates, small fixes.  
326 6913 d 18 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.
 
325 6914 d 2 h palkovsky /SPARTAN/trunk/arch/mips/include/ Forgotten file...  
324 6914 d 5 h palkovsky /SPARTAN/trunk/ MIPS architecture now works without any problems in
- msim: compile as OUTPUT_FORMAT(binary)
- gxemul: compile as OUTPUT_FORMAT(ecoff-littlemips), or create
configuration file for binary format (will be done later)
- simics: compile as OUTPUT_FORMAT(elf32-little), might work with binary
format, didn't try yet.
 
323 6914 d 7 h jermar /SPARTAN/trunk/ Add comments for new floating point modifiers to print.c.
Remove left-over comments from AMD64 and IA-32 page.c.
Coding style clean up.
 
322 6914 d 20 h jermar /SPARTAN/trunk/arch/ia64/ Reduce IA-64 context_t according to IA-64 ABI.

Make IA-64 port compile again.
 
321 6914 d 21 h palkovsky /SPARTAN/trunk/arch/mips/boot/ Fixed bad instructions in loader.  
320 6914 d 22 h palkovsky /SPARTAN/trunk/arch/mips/src/ Bad stack settings. Why did not msim complain??  
319 6916 d 8 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
318 6916 d 9 h jermar /SPARTAN/trunk/ Make AMD64 gencontext.c consistent with MIPS gencontext.c  
317 6916 d 9 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
316 6916 d 10 h jermar /SPARTAN/trunk/arch/ia32/src/ Optimize assembler code according to the knoweledge of IA-32 ABI.  
315 6916 d 11 h jermar /SPARTAN/trunk/arch/ia32/ Make IA-32 userspace stack be aligned on doubleword boundary.
In userspace(), mark "eax" as clobbered register.
 
314 6916 d 19 h palkovsky /SPARTAN/trunk/ Small cleanups  
313 6916 d 19 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
312 6916 d 20 h jermar /SPARTAN/trunk/arch/ia32/ According to IA-32 ABI, %edx and %ecx don't have to be saved accross function calls.
Remove these registers from context_t and adjust context_save() and context_restore() to make use of this fact.
 
311 6916 d 21 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Minor after fixes to madt parsing  
310 6916 d 21 h bondari /SPARTAN/trunk/arch/ia32/src/acpi/ Fixed possible non-consequentive local apic madt entries
Request for peer review - was not possible to test.
 
309 6917 d 9 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
308 6917 d 9 h jermar /SPARTAN/trunk/arch/mips/src/ Just formatting changes.
