799 6842 d 2 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
707 6864 d 9 h decky /kernel/trunk/ allow setting ARCH from Makefile argument  
666 6883 d 1 h jermar /kernel/trunk/ sparc64 work.
Fix clean_window trap handler so that it clears output registers instead of input registers!
Fix interrupt handlers to save global registers.
 
657 6889 d 0 h jermar /kernel/trunk/ sparc64 work.
Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7).
 
626 6895 d 7 h palkovsky /kernel/trunk/ Less checking in kernel config,
allow DEADLOCK_DEBUG only for SMP.
 
604 6898 d 12 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
573 6901 d 4 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
568 6902 d 7 h palkovsky /kernel/trunk/ Configuration tweaks, now supports both CNF and DNF in config.file.  
567 6902 d 22 h palkovsky /kernel/trunk/ Added simple support for arc keyboards on mips.  
566 6902 d 23 h palkovsky /kernel/trunk/ Fixed bug in Intel32/AMD64 boot, that could cause page fault on boot.
Fixes of configuration program.
 
561 6903 d 6 h decky /kernel/trunk/ better way of placing revision, timestamp and arch in banner  
560 6903 d 6 h palkovsky /kernel/trunk/ Added compile tag to build system.  
559 6903 d 8 h palkovsky /kernel/trunk/tools/ Added cancel button  
558 6903 d 8 h palkovsky /kernel/trunk/ Clean up of build system. Use:
make config
make
make clean
 
556 6903 d 22 h palkovsky /kernel/trunk/tools/ Last bugfix tonight.  
555 6903 d 22 h palkovsky /kernel/trunk/tools/ Correct menu even for non-'dialog' based systems.  
554 6903 d 22 h palkovsky /kernel/trunk/ Better configuration dialog  
552 6904 d 1 h palkovsky /kernel/trunk/ Named spinlocks  
550 6904 d 2 h palkovsky /kernel/trunk/ Completely reworked configuration system.  
549 6904 d 3 h palkovsky /kernel/trunk/ Doc cleanup.  
547 6904 d 3 h palkovsky /kernel/trunk/ Added conditions to config system.  
545 6904 d 5 h palkovsky /kernel/trunk/ Added kernel configuration support.  
534 6906 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6906 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
528 6909 d 2 h jermar /kernel/trunk/ sparc64 work.
The context_save/context_restore needed two other improvements.
First, storing of %fp because of window_fills.
Second, flushing all active windows before CONTEXT_LOAD to make CWP - 1 the overlap window.
 
527 6909 d 9 h jermar /kernel/trunk/ saprc64 work.
Perform leaf-procedure optimization for context_save and context_restore.
 
526 6909 d 9 h jermar /kernel/trunk/ sparc64 work.
No need to save/restore local registers.
 
501 6918 d 8 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
466 6932 d 7 h jermar /SPARTAN/trunk/ Rename build.ia32 to tools/build.
Point build.{amd64,ia32,ia64,mips32,ppc32,sparc64} to tools/build.
The same for clean.
 
426 6941 d 9 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.
 
414 6953 d 13 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 6953 d 23 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.
 
341 6989 d 9 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
332 6990 d 10 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.
 
318 6994 d 13 h jermar /SPARTAN/trunk/ Make AMD64 gencontext.c consistent with MIPS gencontext.c  
317 6994 d 13 h palkovsky /SPARTAN/trunk/ MIPS exception now saves all necesssary information only on stack.  
306 6995 d 14 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.
 
297 6996 d 11 h palkovsky /SPARTAN/trunk/ Symtab now contains variables  
293 6996 d 23 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
288 6997 d 5 h jermar /SPARTAN/trunk/ Create tools/ directory.
Move helper scripts and tools out of src/ and arch/.
