911 6722 d 0 h jermar /kernel/trunk/arch/ia64/ ia64 work.

Change heavyweight interrupt handler to use bank 0 registers instead of AR.KR0 and AR.KR1.
This prevents userspace from the possibility to see what addresses are being used by kernel.

Store kernel stack address in bank 0 r23 instead of AR.KR7. Again, userspace will not be
able to read the address of its kernel stack.

Increase FRAME_SIZE to 64K as this is the first supported page size in which will fit
thread's combined register and memory stack. (RSE can write out as many as 16K.)		  
910 6722 d 3 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6724 d 16 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		  
904 6724 d 21 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).		  
903 6724 d 23 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Add code needed for running multiple address spaces and location of kernel stack
after switch from userspace.		  
902 6726 d 4 h jermar /kernel/trunk/ ia64 work.
More capable TLB miss handlers.
The ia64 kernel now passes mm/mapping1 test.

Fix generic hash table to properly initialize lists.

Change page_ht() to properly initialize inserted PTE's.
Change format of generic page hash table PTE's.		  
901 6726 d 6 h jermar /kernel/trunk/arch/ ia64 work.
Provide PA2KA(identity) mapping for kernel data references via Alternate Data TLB Fault handler.
Add before_thread_runs_arch() that maps kstack, if necessary.
Add easy to use dtlb_mapping_insert() for comfortable insertion of kernel data mappings.		  
900 6726 d 23 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Proper TLB fault handlers' headers and prototypes.
PFN 0 needs no longer be marked unavailable to frame allocator.		  
899 6727 d 0 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.		  
898 6727 d 3 h jermar /kernel/trunk/ Minor changes.  
897 6727 d 17 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.		  
895 6727 d 20 h jermar /kernel/trunk/ sparc64 work.
Very raw and fragile preliminary standalone keyboard support - polling mode only.
Because of a workaround in Simics, the scan codes are the same as on ia32.		  
894 6727 d 23 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6728 d 4 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.

ia32 + ia64 cosmetic changes.		  
892 6729 d 0 h vana /kernel/trunk/ Itanium active keyboard  
889 6729 d 3 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
884 6729 d 4 h decky /kernel/trunk/arch/ppc32/ move ppc boot loader to /boot tree  
883 6729 d 5 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Switch console to framebuffer (needs proper detection and initialization).
No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.		  
881 6729 d 5 h decky /kernel/trunk/arch/ppc32/boot/ PPC32 boot loader preparation  
879 6729 d 21 h vana /kernel/trunk/arch/ia64/ Itanium kernel page extended to maximum (256M) repaired RR manipulation functions, paging setuping function and added some comments.  
878 6730 d 3 h vana /kernel/trunk/ Active keyboard read for ia32  
877 6730 d 21 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6731 d 5 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
872 6732 d 16 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
871 6732 d 17 h vana /kernel/trunk/arch/ia64/include/ C version of Itanium FADDR()  
870 6732 d 17 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6732 d 17 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
868 6733 d 2 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6733 d 2 h jermar /kernel/trunk/ Move OFW functionality of ppc32 memory_init to genarch so that the code can also be used by sparc64.
sparc64 is now close to broken as it lacks functionality to provide identity mapping for the whole phyisical memory.		  
864 6733 d 17 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6733 d 17 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add initial TLB miss handlers.		  
861 6734 d 3 h jermar /kernel/trunk/arch/sparc64/include/ Add atomic_add() operation for sparc64.  
860 6734 d 17 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy		  
854 6735 d 22 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
853 6737 d 1 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 6737 d 2 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 6737 d 19 h palkovsky /kernel/trunk/arch/mips32/src/ removed debugging printf.  
850 6737 d 19 h palkovsky /kernel/trunk/ Small bugs fixed after running all tests on mips.  
849 6737 d 19 h palkovsky /kernel/trunk/arch/mips32/include/mm/ Fixed mips-big endian TLB problems.  
847 6737 d 22 h jermar /kernel/trunk/arch/sparc64/ Improve comments in start.S.
