510 6836 d 4 h jermar /kernel/trunk/ Add chardev_t.
This type is meant to abstract any input character device such as keyboard, serial port etc.
Add stdin.
Add dummy kconsole.
 
509 6836 d 6 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
506 6836 d 9 h decky /kernel/trunk/ preparation for init task loading  
503 6836 d 11 h jermar /kernel/trunk/ Rename arch_late_init() to arch_pre_smp_init().
Add arch_post_smp_init().
Enable IRQ_KBD on ia-32 (doesn't work on Bochs SMP, works on Bochs UP).
 
501 6836 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6837 d 5 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
486 6844 d 5 h jermar /SPARTAN/trunk/ Revert to -O3 for all architectures as the mips32 bug got fixed.  
484 6844 d 5 h palkovsky /SPARTAN/trunk/arch/mips32/src/ Fixed typo in context save.  
483 6844 d 8 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 6847 d 13 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 6848 d 14 h jermar /SPARTAN/trunk/ Define atomic_t type.  
472 6849 d 13 h jermar /SPARTAN/trunk/ Changes in build system.
For .S targets, always do -D__ASM__.
Remove unnecessary #define __ASM__ from various *.S files.
At the end of build, generate disassembler dump for kernel.raw.

ia64 work.
Better General Exception handler.
 
461 6850 d 15 h decky /SPARTAN/trunk/ link kernel in ARCH's native format first, then use objcopy to create output format  
458 6850 d 15 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
457 6850 d 16 h decky /SPARTAN/trunk/ new build system almost finished  
455 6851 d 4 h decky /SPARTAN/trunk/ new build system upgrade
finished work for IA-32, IA-64, PPC-32, SPARC-64
 
431 6855 d 15 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Exclude external interrupt from universal_handler() scope.
 
430 6857 d 5 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
429 6857 d 10 h jermar /SPARTAN/trunk/arch/mips32/ For now, compile with -mhard-float.
Libraries required by -msoft-float are not part of gcc.
Moreover, ld doesn't warn about undefined symbols.
 
426 6859 d 14 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 6860 d 11 h cejka /SPARTAN/trunk/arch/mips32/include/ Fixed problem with va_arg macro for mips32. This solves problem with printing 64bit values on it.  
418 6867 d 7 h jermar /SPARTAN/trunk/ sparc64 infrastructure.  
414 6871 d 18 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 6872 d 4 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 6879 d 7 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6882 d 4 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).
 
397 6882 d 18 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6883 d 15 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.)
 
395 6884 d 6 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.
 
394 6884 d 6 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 6885 d 5 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 6885 d 16 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().
 
376 6894 d 11 h jermar /SPARTAN/trunk/ Move kernel build files one level up the directory tree.
Fix paths in your testing environment!
 
368 6898 d 14 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
364 6899 d 17 h palkovsky /SPARTAN/trunk/ Added support for msim with 4kc instructions.
Fixed support for upstream msim.

Small boot fix on Indy.
 
363 6900 d 6 h jermar /SPARTAN/trunk/arch/ Fix copyright notices.  
361 6900 d 7 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
345 6907 d 7 h palkovsky /SPARTAN/trunk/arch/mips32/include/  
344 6907 d 7 h palkovsky /SPARTAN/trunk/ Added more code to arc.
Fixed bad name in byteorder.h
 
342 6907 d 14 h jermar /SPARTAN/trunk/arch/ Rename ppc port to ppc32.
