612 6811 d 20 h jermar /kernel/trunk/arch/mips32/src/mm/ Weaken the assumption, that PageMask register contains the right mask everytime.
As a result, TLB exceptions will explicitly write this register when filling TLB entry.
Adjust tlb_print() on mips32 to print PageMask as well.
 
610 6811 d 22 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6811 d 22 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6811 d 23 h palkovsky /kernel/trunk/ Fixed weird simics panic.
Run kconsole, if we panic. This currently works in gxemul,
simics. In mips we need to modify the simulator.
On ia32 we need a function, that would speak directly to the chip
and fetch the character using polling.
 
606 6812 d 0 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
605 6812 d 4 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Allow for different ARC frame size and kernel frame size.  
599 6813 d 1 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6813 d 1 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6813 d 19 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6813 d 20 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
593 6813 d 21 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6813 d 22 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 6813 d 23 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 6814 d 14 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
575 6814 d 15 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 6814 d 21 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6814 d 21 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
569 6815 d 17 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
567 6816 d 15 h palkovsky /kernel/trunk/ Added simple support for arc keyboards on mips.  
548 6817 d 20 h jermar /kernel/trunk/ Cleanup and fixes.  
546 6817 d 21 h palkovsky /kernel/trunk/arch/mips32/ Fixed mips gxemul architecture.  
536 6819 d 18 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6819 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6819 d 20 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 6819 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
511 6831 d 15 h jermar /kernel/trunk/ Enable dummy kconsole for ia32 and amd64 (UP mode works).  
510 6831 d 16 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 6831 d 18 h jermar /kernel/trunk/ Basic keyboard support for mips32 (msim).  
503 6831 d 23 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 6832 d 0 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6832 d 17 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 6839 d 17 h palkovsky /SPARTAN/trunk/arch/mips32/src/ Fixed typo in context save.  
483 6839 d 20 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 6845 d 1 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 6846 d 3 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
414 6867 d 6 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 6867 d 16 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 6874 d 19 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
399 6877 d 16 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 6878 d 6 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
