575 6761 d 6 h palkovsky /kernel/trunk/ Added generic exc_register/exc_dispatch functions,
copied from ia32 architecture. Currently only mips32 uses them.

The chardev_t can now be both input & output device (was
needed for serial driver).

Broken other architectures - ia64, sparc, powerpc will not compile.

Mips32 supports input on all msim, gxemul, indy(tested emulation
in gxemul, loses characters), simics. Simics serial line
is done using polling, I was unable to make it produce
an interrupt when the key was pressed.
 
574 6761 d 12 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6761 d 12 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
567 6763 d 6 h palkovsky /kernel/trunk/ Added simple support for arc keyboards on mips.  
534 6766 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6766 d 11 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
509 6778 d 9 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
501 6778 d 15 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
483 6786 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 6789 d 16 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 6790 d 16 h jermar /SPARTAN/trunk/ Define atomic_t type.  
457 6792 d 18 h decky /SPARTAN/trunk/ new build system almost finished  
426 6801 d 16 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 6802 d 14 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 6813 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 6814 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 6821 d 10 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6824 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 6825 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 6826 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)
