1094 6673 d 7 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6676 d 0 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6676 d 16 h jermar /kernel/trunk/ Support for user space threads.  
1044 6677 d 5 h jermar /kernel/trunk/ Page table locking.  
1037 6677 d 6 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
983 6679 d 3 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6679 d 21 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6679 d 22 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.		  
955 6679 d 22 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6681 d 0 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6681 d 9 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6690 d 18 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		  
897 6693 d 18 h jermar /kernel/trunk/ sparc64 work.
Fix KBD_VIRT_ADDRESS.
Call before_thread_runs() prior to the switch to the thread's stack. Add comment why this is crucial.
Add after_thread_ran() to the scheduler.
Add before_thread_runs_arch() and after_thread_ran_arch() for sparc64, mapping/demapping thread's kernel stack.
Add dummy after_thread_ran_arch() to all other architectures.
Add dtlb_insert_mapping() to promote code reuse.		  
853 6703 d 2 h palkovsky /kernel/trunk/arch/mips32/ Some arc bios tweaks. Wanted to print configuration data, but
the ARC seems to return strange values.
Newport graphics card does not seem to be easy to port, give up now.		  
852 6703 d 3 h palkovsky /kernel/trunk/ Fixes in memory allocator
- proper kernel blacklisting, when kernel not loaded on page boundary
- correct zone adding in zone list (how could this work??)		  
851 6703 d 20 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6703 d 20 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
838 6707 d 7 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6707 d 8 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6707 d 19 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6711 d 2 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).		  
830 6711 d 4 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().		  
827 6711 d 18 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
820 6712 d 19 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.		  
817 6713 d 4 h palkovsky /kernel/trunk/ Small cleanup.  
815 6713 d 5 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6713 d 5 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
812 6713 d 20 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
799 6714 d 21 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
797 6715 d 0 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6715 d 1 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.		  
794 6715 d 2 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6715 d 3 h jermar /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.		  
765 6718 d 21 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6719 d 2 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
760 6719 d 5 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 6720 d 18 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.		  
755 6721 d 17 h jermar /kernel/trunk/ Change page_mapping_find/insert interfaces to take as_t * as first argument
and not asid_t as second argument. This change was necessitated by the
removal of mapping array from as_area_t and the fact that an address
space doesn't have an ASID when it is created.		  
730 6731 d 0 h jermar /kernel/trunk/ Finalize ASID management for sparc64 and mips32 by making use of FIFO queue of ASIDs.  
727 6732 d 20 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
