911 6780 d 1 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 6780 d 4 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6780 d 6 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
908 6782 d 3 h jermar /uspace/trunk/ Start ia64 uspace.  
907 6782 d 5 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6782 d 17 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		  
905 6782 d 19 h jermar /kernel/trunk/ Upgrade toolchain build scripts to install binutils 2.16.1 and gcc 4.1.0.
The only exception is ia64, where the kernel does not build with gcc 4.1.0.		  
904 6782 d 22 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).		  
903 6782 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 6784 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 6784 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 6784 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 6785 d 0 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.		  
898 6785 d 4 h jermar /kernel/trunk/ Minor changes.  
897 6785 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.		  
896 6785 d 17 h jermar /kernel/trunk/genarch/src/fb/ Improve framebuffer speed by using optimised memcpy().  
895 6785 d 21 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 6786 d 0 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6786 d 5 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.

No native keyboard support, so far.
Memory management trap handler fixes.
Do not use OpenFirmware trap table anymore.
