1074 6662 d 22 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1070 6663 d 0 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6663 d 9 h jermar /kernel/trunk/ Support for user space threads.  
1024 6664 d 15 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1019 6664 d 18 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
984 6665 d 19 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6665 d 20 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6666 d 0 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6666 d 14 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.		  
957 6666 d 14 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
955 6666 d 15 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6666 d 18 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
940 6667 d 15 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6667 d 16 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6674 d 21 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6677 d 10 h palkovsky /kernel/trunk/ Added lazy fpu context allocation.
- threads that don't use fpu, don't get allocated fpu context
- fpu context alignment on AMD64 nicely disappeared		  
894 6680 d 17 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6687 d 10 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
854 6688 d 16 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
832 6697 d 12 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6697 d 18 h jermar /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).		  
825 6698 d 17 h jermar /kernel/trunk/ 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.		  
823 6699 d 11 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.		  
814 6699 d 22 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
765 6705 d 13 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
763 6705 d 19 h jermar /kernel/trunk/ Modify frame.h to use shifting instead of multiplication and division.
Define FRAME_WIDTH for all architectures.		  
760 6705 d 22 h jermar /kernel/trunk/ 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 6707 d 10 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.		  
750 6709 d 14 h jermar /kernel/trunk/ ia32 SMP updates.
Update info about supported version of Bochs (bump the counter to 2.2.6).
Add Task Priority Register type and initialize this register to a known state.		  
727 6719 d 12 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.		  
703 6725 d 21 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().		  
693 6730 d 17 h decky /kernel/trunk/arch/ia32/ simplify and cleanup ia32 boot process, remove obsolete stuff  
674 6734 d 23 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
672 6736 d 12 h jermar /kernel/trunk/arch/ia32/ ia32 work.
Initialize LDR and DFR registers in Local APIC so that logical destination addresses work.		  
633 6754 d 12 h palkovsky /kernel/trunk/arch/ Fixes of compilation of atomic.  
631 6754 d 13 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
627 6754 d 17 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 6754 d 18 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.		  
622 6755 d 14 h palkovsky /kernel/trunk/ Better gcc CALLER implementation  
606 6757 d 19 h palkovsky /kernel/trunk/ Small kconsole readline changes.
Some mips tweaks to allow for real keyboard support in indy.
