sparc64 work.
Relocate kernel to 4M.
830
6691 d 2 h
jermar
/kernel/trunk/
Make ASID FIFO for mips32 be allocated statically.
Make ASID FIFO for sparc64 and ia64 be allocated dynamically.
Fix ia64 to call asid_fifo_init().
All three architectures now call asid_fifo_init() from as_arch_init().
823

Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
821
6692 d 18 h
jermar
/kernel/trunk/arch/sparc64/src/mm/
Do not add CONFIG_STACK_SIZE to kernel.size.
820
6692 d 18 h
jermar
/kernel/trunk/
Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
815

/kernel/trunk/
Fix sparc64 and ia64 to work with the changed frame allocator.
Fix ppc32 to at least compile.
813
6693 d 16 h
jermar
/kernel/trunk/
Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.
Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.

/kernel/trunk/
Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.
792
6695 d 2 h
jermar
/kernel/trunk/
Page hash table architectures now use generic hash table to manage
mappings.
756
6700 d 16 h
jermar
/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.
730
6710 d 23 h
jermar
/kernel/trunk/
Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.
727
6712 d 18 h
jermar
/kernel/trunk/
New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
684
6724 d 1 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.
646
6744 d 17 h
jermar
/kernel/trunk/
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.
630
6747 d 20 h
jermar
/kernel/trunk/arch/sparc64/
sparc64 work.
Register window clean, spill and fill handlers.
627

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.
619
6749 d 14 h
jermar
/kernel/trunk/arch/sparc64/
sparc64 work.
Functions for disabling/enabling MMU.
TLB initialization.
Identity mapping of first 4M for kernel.
Switch to kernel copy of trap table.
617
6749 d 17 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).
613
6750 d 16 h
jermar
/kernel/trunk/arch/sparc64/
sparc64 work.
More ITLB and DTLB controlling functions.

Missing tlb.c from last commit.

Buddy allocator cleanup and fixes II.
- Rewrite IS_BUDDY_LEFT_BLOCK so that it does not need floating point on some architectures (e.g. IA-64).
- Get rid of IS_BUDDY_RIGHT_BLOCK.
- Make sparc64 use zone_create_in_region.

sparc64 work.
Add context_save(), context_set() and context_restore().
Remove putchar() definition from ofw.c.
Add sparc64 putchar().
Add ppc32 putchar() (i.e. the original ofw.c putchar()).
Make arg.h use the builtin va_* constructs.
