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) |

This type is meant to abstract any input character device such as keyboard, serial port etc.

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. |

Make the buddy system more general.
Store implementation defined pointer in buddy_system_t.

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. |

Move src/ and include/ to generic. |
|

6925 d 22 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. |
|

Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.

Add ALIGN() macro.
Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review. |

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.) |

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. |

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(). |

Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.
Small changes elsewhere. |

Implement splitting and concatenation for headless doubly-linked circular lists.
This is going to be needed during implementation of buddy system operations for zones.
Add doxygen-style comments to all functions in list.h. |
|

/SPARTAN/trunk/ |
Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations.
Reorganize #include's in scheduler.c.
Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions. |

Revert previous change in frame_t as it broke IA-64.
(Most likely some alignment problem.)
Rename heap_init(), malloc() and free(), respectively, to early_heap_init(), early_malloc() and early_free(), respectively.
Define new macros malloc() and free(). They are to be replaced by real functions some day. |
