534 6758 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6758 d 11 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6770 d 9 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
501 6770 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6778 d 11 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.
 
477 6781 d 17 h vana /SPARTAN/trunk/ Atomic inc & dec functions synchronized on all ia32,ia64 and mips platforms. Now there are 3 versions which returns no value, new value and old value och changed variable.  
475 6782 d 17 h jermar /SPARTAN/trunk/ Define atomic_t type.  
457 6784 d 19 h decky /SPARTAN/trunk/ new build system almost finished  
426 6793 d 17 h jermar /SPARTAN/trunk/ sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.
 
425 6794 d 15 h cejka /SPARTAN/trunk/arch/mips32/include/ Fixed problem with va_arg macro for mips32. This solves problem with printing 64bit values on it.  
414 6805 d 21 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.
 
413 6806 d 7 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
403 6813 d 10 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6816 d 7 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).
 
396 6817 d 18 h jermar /SPARTAN/trunk/ Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)
 
394 6818 d 9 h jermar /SPARTAN/trunk/arch/mips32/ MIPS32 memory management work.
Fix some bugs introduced yesterday (PTL3 index is indeed calculated by >> 14).
Introduce two new bits in pte_t (i.e. 'a' and 'w').
Implement TLB Invalid Exception and TLB Modified Exception. (Needs review and testing)
 
391 6819 d 9 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
389 6819 d 19 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().
 
363 6834 d 9 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.  
361 6834 d 10 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
345 6841 d 10 h palkovsky /SPARTAN/trunk/arch/mips32/include/  
344 6841 d 10 h palkovsky /SPARTAN/trunk/ Added more code to arc.
Fixed bad name in byteorder.h
 
341 6841 d 17 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
338 6842 d 16 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
334 6842 d 17 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 6842 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.
 
330 6843 d 13 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 6843 d 13 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6844 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.
 
325 6844 d 14 h palkovsky /SPARTAN/trunk/arch/mips/include/ Forgotten file...  
319 6846 d 20 h jermar /SPARTAN/trunk/arch/mips/ Copyright notices changes.  
317 6846 d 21 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
313 6847 d 8 h palkovsky /SPARTAN/trunk/arch/ MIPS bug fixes.
Added usermode to MIPS, unfortunately impossible to test until
MM is ready.
 
307 6847 d 21 h palkovsky /SPARTAN/trunk/ Fixed things broken by last commit.  
306 6847 d 22 h palkovsky /SPARTAN/trunk/ Fixed mips boot process.
On interrupt saving registers, save $lo, $hi.
Add interrupt naming to asm files (mips).
Save only necessary registers on context switch (see mips ABI).
Fixed copyright info.
 
292 6849 d 7 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().
 
266 6850 d 16 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.

Added cpuid support.
 
240 6852 d 12 h palkovsky /SPARTAN/trunk/arch/mips/ Fixed bad register assignment in atomic.h.
Added -msoft-float so that it does not call coprocessor and it works withou doubles.
Removed undefined symbol from tlb.c. Unfortunately
mips linker does not report missing symbols.
