599 6772 d 11 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6772 d 12 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6773 d 6 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6773 d 7 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
593 6773 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6773 d 8 h palkovsky /kernel/trunk/ Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned.
 
588 6773 d 9 h palkovsky /kernel/trunk/ Added support for backspace
- printing '\b' should move the cursor one char to the left
- backspace key should return '\b' to application
 
577 6774 d 1 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
575 6774 d 2 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 6774 d 7 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6774 d 7 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6775 d 3 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
567 6776 d 1 h palkovsky /kernel/trunk/ Added simple support for arc keyboards on mips.  
548 6777 d 6 h jermar /kernel/trunk/ Cleanup and fixes.  
546 6777 d 7 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
536 6779 d 5 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6779 d 6 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6779 d 6 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6779 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
511 6791 d 2 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
510 6791 d 2 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 6791 d 4 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
503 6791 d 10 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 6791 d 11 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6792 d 4 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.
 
484 6799 d 4 h palkovsky /SPARTAN/trunk/arch/mips32/src/ Fixed typo in context save.  
483 6799 d 6 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.
 
472 6804 d 12 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.
 
458 6805 d 14 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
414 6826 d 16 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 6827 d 2 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 6834 d 6 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6837 d 3 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 6837 d 16 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6838 d 13 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 6839 d 4 h jermar /SPARTAN/trunk/arch/mips32/src/mm/ Small fix.
MIPS32 pte_t.c is not bool.
 
394 6839 d 4 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 6840 d 4 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 6840 d 15 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().
 
368 6853 d 12 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
