906 6782 d 22 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 6783 d 3 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).		  
903 6783 d 4 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 9 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 11 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 6785 d 4 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 5 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.		  
898 6785 d 9 h jermar /kernel/trunk/ Minor changes.  
897 6785 d 22 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 6786 d 2 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 5 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6786 d 10 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 6787 d 5 h vana /kernel/trunk/ Itanium active keyboard  
889 6787 d 9 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
884 6787 d 10 h decky /kernel/trunk/arch/ppc32/ move ppc boot loader to /boot tree  
883 6787 d 10 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 6787 d 10 h decky /kernel/trunk/arch/ppc32/boot/ PPC32 boot loader preparation  
879 6788 d 3 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 6788 d 8 h vana /kernel/trunk/ Active keyboard read for ia32  
877 6789 d 2 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.		  
873 6789 d 10 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.		  
872 6790 d 22 h vana /kernel/trunk/ Init stack base fix
Removing commented code		  
871 6790 d 22 h vana /kernel/trunk/arch/ia64/include/ C version of Itanium FADDR()  
870 6790 d 22 h vana /kernel/trunk/arch/ia64/ Removed forgoten debug function and reverted my mistake  
869 6790 d 23 h vana /kernel/trunk/ Uaaaaaaa ;-) Itanium Paging !!!!!! ;-)  
868 6791 d 7 h jermar /kernel/trunk/arch/sparc64/src/mm/ Add missing file.  
867 6791 d 7 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 6791 d 23 h jermar /kernel/trunk/arch/sparc64/include/trap/ Add forgotten file.  
863 6791 d 23 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.

ppc32 memcpy		  
854 6794 d 4 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.
