Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3. |
|

/kernel/trunk/ |
Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared). |

Remove WAKEUP_IPI stuff.
Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL. |

Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print. |

Added MIPS userspace. Currently can't make it work in gxemul. |
|

Add PAGE_WIDTH to aid divisions by PAGE_SIZE. |
|
763 |
6805 d 18 h |

/kernel/trunk/ |
Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures. |

mips32 is not supposed to allocate page table.
This is done by the generic code now.
Remove PTL0 pointer as it is not needed.
Remove GET_PTL0_ADDRESS from kernel.
Update sparc64 comments in barrier.h. |
|
756 |
6807 d 9 h |

/kernel/trunk/ |
Memory management work.
Remove the last (i.e. 'root') argument from page_mapping_insert() and page_mapping_find().
Page table address is now extracted from the first (i.e. 'as') argument.
Add a lot of infrastructure to make the above possible.
sparc64 is now broken, most likely because of insufficient identity mapping of physical memory. |

Convert ASID management of ia64 to ASID FIFO mechanism.
18-bit RIDs are supported. |
|

sparc64 work.
13 bits wide means the max value is 8191 and not 0x8191. |
|

/kernel/trunk/ |
Unlock address space prior TLB shootdown in get_asid() to unify
the locking order among mips32, sparc64 and ia64.
Add ASID_STEALING_ENABLED macro to disable the stealing part on ia64
in a clean way. |
|
727 |
6819 d 11 h |

/kernel/trunk/ |
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes. |
|
703 |
6825 d 20 h |

/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(). |

Compilation fixes. |

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

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. |
|

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

Better gcc CALLER implementation |

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. |

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

Different sizes of TLB on mips32.
R4000 has 48 entries, 4kc has only 16 entries. |

ptlb command (currently usable on mips32 only). |

Move all MIPS exceptions to generic dispatcher.
Align size in malloc() to __native size, some architectures
don't like it unaligned. |

Added exception printing.
It does not work correctly on SMP architectures :-/
Preemption error.... |
|

6860 d 9 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. |

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. |
