Context again. It turns out, according to SCD 2.4, that registers that didn't have to be saved were saved (%o1 - %o5) and
registers that had to be saved were not saved (%i0 - %i5, %l0 - %l7). |

/kernel/trunk/generic/src/ |
Fix page_insert_mapping().
Some architectures (e.g. ia32) need to have the lower-numbered PTL's flagged as PAGE_WRITE in order to prevent overriding protection bits of leaf TTE's. |

/kernel/trunk/ |
remove arch/$ARCH/boot where not needed, change global Makefile accordingly
remove early_mapping() (breaks ppc32 for now)
change early heap initialization (required for init to work) |

/kernel/trunk/ |
sparc64 work.
Implement interrupt_disable(), interrupt_enable(), interrupt_restore() and interrupt_read() functions.
Fix context save/restore to save/restore register %i7. |

Fix cpu_init(): frame_alloc() can return 0 as the valid address of block of frames. Do not signal error.
sparc64 work.
Reorganize kernel vs. userspace memory layout.
Add panic_printf().
Turn dummy() into nop rather than into infinite loop. |

CPU identification. |

Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed. |

Better way of trap table organization.
Kernel trap handlers now "stay" on addresses on wich they were linked. |
|

Fixes of compilation of atomic. |

Add trap_install_handler().
Use trap_install_handler() to install register window clean, spill and fill handlers. |

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. |

Less checking in kernel config,
allow DEADLOCK_DEBUG only for SMP. |

We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning. |
|
| 624 |

/kernel/trunk/generic/ |
Add LIST_INITIALIZE() macro to declare and initialize statically allocated lists. |
|
| 623 |
6739 d 7 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. |

Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table. |

/kernel/trunk/arch/mips32/src/mm/ |
Unify mips32 and sparc64 tlb_invalidate_all() semantics: do not invalidate locked/wired TLB entries. |
|
| 617 |
6740 d 19 h |
jermar |
/kernel/trunk/arch/sparc64/ |
sparc64 work.
Support for TLB Demap operations.
Add tlb_invalidate(), tlb_invalidate_asid() and tlb_invalidate_page() (latter two are broken as they ignore asid). |
|

Cleanups to make it compile with -Wall. Did not catch everything yet. |

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. |

/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. |

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. |

Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy. |
