1097 6774 d 7 h palkovsky /kernel/trunk/arch/mips32/src/ Still better syscall calling convention for mips.  
1096 6774 d 7 h palkovsky /kernel/trunk/ Cleanup of mips
- inline register reads
- better fpu disable/enable - global settings is automatically propagated to task
- fast syscall		  
1094 6774 d 10 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6777 d 3 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1066 6777 d 19 h jermar /kernel/trunk/ Support for user space threads.  
1044 6778 d 8 h jermar /kernel/trunk/ Page table locking.  
1037 6778 d 9 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
983 6780 d 5 h palkovsky /kernel/trunk/ Fixed shrinking of as area.  
959 6781 d 0 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6781 d 1 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 6781 d 1 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6782 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
924 6782 d 12 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
906 6791 d 20 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 6794 d 21 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 6804 d 5 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 6804 d 6 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 6804 d 23 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6804 d 23 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
838 6808 d 10 h palkovsky /kernel/trunk/ Added untested support for 2 & 4-byte (15-bit & 24-bit depth) framebuffer.  
837 6808 d 11 h palkovsky /kernel/trunk/ Moved framebuffer to genarch.  
836 6808 d 21 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
831 6812 d 5 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 6812 d 7 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 6812 d 21 h palkovsky /kernel/trunk/ Unimportant changes regarding FPU context.  
820 6813 d 22 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 6814 d 7 h palkovsky /kernel/trunk/ Small cleanup.  
815 6814 d 8 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.		  
814 6814 d 8 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
812 6814 d 23 h jermar /kernel/trunk/ Documentation and dot.bochsrc upgrade.  
799 6816 d 0 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
797 6816 d 3 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6816 d 4 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 6816 d 5 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6816 d 6 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 6820 d 0 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.  
764 6820 d 5 h palkovsky /kernel/trunk/ Tested basic non-cached slab allocation.  
760 6820 d 8 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 6821 d 21 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 6822 d 20 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.
