724 6702 d 5 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
717 6704 d 7 h decky /kernel/trunk/ remove obsolete in-kernel userspace code
remove CONFIG_USERSPACE switch, uspace support is configured at run-time
 
704 6706 d 10 h jermar /kernel/trunk/ Make various mips32 tlb manipulation functions preserve EntryHi register.

Cleanup and more precise comments for previous commit.
 
703 6706 d 13 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
689 6711 d 9 h bondari /kernel/trunk/ Frame alloc test #1  
687 6711 d 10 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
684 6711 d 11 h jermar /kernel/trunk/ Memory management work.
Move generic 4-level page table interface to genarch
and enable architectures to use different virtual memory
mechanisms (e.g. page hash tables).
Start page hash table support.
Switch ia64 and sparc64 to page hash tables.
Other architectures keep on using 4-level page table interface.
 
674 6715 d 14 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
673 6716 d 4 h jermar /kernel/trunk/ Add 'version' and 'cpus' kconsole commands.
Remove leading p from names of p* commands.
 
655 6730 d 8 h jermar /kernel/trunk/arch/ Compilation fixes.  
635 6734 d 2 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.
 
631 6735 d 4 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
627 6735 d 9 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.
 
625 6735 d 10 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
623 6735 d 16 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.
 
622 6736 d 5 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
618 6737 d 3 h jermar /kernel/trunk/arch/mips32/src/mm/ Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries.  
615 6737 d 15 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
614 6738 d 0 h palkovsky /kernel/trunk/ Added support for mips breakpoints.
We have a kind of kernel debugger :-)
Breakpoints on JMP/Branch instructions are not supported and
they are reported after the breakpoint is fired and exited as
a BranchDelay exception. If we found a way, how to detect these
instructions, we would be able to support them as 'one-time' breakpoints.
 
612 6738 d 6 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 6738 d 8 h palkovsky /kernel/trunk/arch/mips32/ Cleanup of unnecessary things.  
609 6738 d 9 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6738 d 9 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 6738 d 10 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
 
605 6738 d 14 h palkovsky /kernel/trunk/arch/mips32/src/drivers/ Allow for different ARC frame size and kernel frame size.  
604 6738 d 15 h palkovsky /kernel/trunk/ Make it boot on SGI indy again.  
600 6739 d 11 h jermar /kernel/trunk/arch/mips32/ Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries.
 
599 6739 d 11 h jermar /kernel/trunk/arch/mips32/ Fixes for mips32 invalidation functions.  
598 6739 d 12 h jermar /kernel/trunk/arch/mips32/src/mm/ TLB invalidation functions for mips32. Not deployed yet. Not tested.  
595 6740 d 6 h palkovsky /kernel/trunk/ Fixed bug in vm.c that turned off preemption. Found in versions 390:391.  
594 6740 d 7 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
593 6740 d 8 h palkovsky /kernel/trunk/arch/mips32/src/ Fixed typo.  
590 6740 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 6740 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
 
581 6740 d 14 h palkovsky /kernel/trunk/ Small debug changes.  
578 6741 d 0 h palkovsky /kernel/trunk/ Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error....
 
577 6741 d 1 h palkovsky /kernel/trunk/ Some small fixes, basic changes to ia64 & ppc32 without testing.  
575 6741 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 6741 d 7 h palkovsky /kernel/trunk/ Merged msim & gxemul native keyboards.  
573 6741 d 8 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.
