925 6635 d 17 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
924 6635 d 19 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6636 d 2 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
922 6638 d 5 h jermar /kernel/trunk/genarch/src/mm/ Fix generic page hash table to align down page addresses.
This was the ia64 userspace show stopper.
 
921 6638 d 10 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
 
919 6638 d 15 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.
 
916 6640 d 16 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.
 
915 6640 d 17 h jermar /kernel/trunk/arch/ia64/ ia64 work.
- Another item had to be allocated on stack to remember new value written to ar.bspstore.
Fix heavyweight interruption handler to calculate RSC.loadrs from the new value of ar.bspstore
instead from the old one.
Uncomment instructions switching ar.bspstore.
- Configure kernel with 512M of memory.
 
912 6642 d 7 h jermar /kernel/trunk/ ia64 work.

ivt.S:
Detect userspace stack in heavyweight handler and switch to kernel stack.
Remember the old stack pointer.
As for register stack, kernel stack is assumed still.
Fix alignment issues that showed when STACK_ITEMS was odd.
Fix ld8 instruction that did subtraction of 8 instead of addition of 8.

scheduler.c:
Change before_thread_runs_arch() to calculate address of top of the stack
for the interrupt handler.
 
911 6642 d 11 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 6642 d 14 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6642 d 16 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
907 6644 d 15 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6645 d 3 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 6645 d 5 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 6645 d 8 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).
 
903 6645 d 9 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 6646 d 14 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 6646 d 16 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 6647 d 9 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 6647 d 10 h jermar /kernel/trunk/arch/ ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.
 
898 6647 d 14 h jermar /kernel/trunk/ Minor changes.  
897 6648 d 3 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 6648 d 3 h jermar /kernel/trunk/genarch/src/fb/ Improve framebuffer speed by using optimised memcpy().  
895 6648 d 7 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 6648 d 10 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6648 d 15 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 6649 d 10 h vana /kernel/trunk/ Itanium active keyboard  
891 6649 d 14 h palkovsky /kernel/trunk/genarch/src/fb/ Fixed getpixel_1byte to work with 3:2:3 color scheme.  
889 6649 d 14 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Forgotten fb.h for sparc64.  
886 6649 d 14 h jermar /kernel/trunk/genarch/src/fb/ Change putpixel1() to look better.  
884 6649 d 15 h decky /kernel/trunk/arch/ppc32/ move ppc boot loader to /boot tree  
883 6649 d 15 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.
 
882 6649 d 15 h jermar /kernel/trunk/generic/src/lib/ Improved version of generic memcpy().
Should improve frame buffer impression.
 
881 6649 d 16 h decky /kernel/trunk/arch/ppc32/boot/ PPC32 boot loader preparation  
880 6649 d 17 h jermar /kernel/trunk/generic/include/mm/ Fix conflict between asid_get() macro and function definitions.  
879 6650 d 8 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 6650 d 13 h vana /kernel/trunk/ Active keyboard read for ia32  
877 6651 d 7 h jermar /kernel/trunk/arch/sparc64/ Fixes in sparc64 preliminary TLB miss handler.
Compute and insert identity mapping for kernel on the fly.
 
873 6651 d 15 h jermar /kernel/trunk/arch/sparc64/ sparc64 work.
Add more MMU helper functions and make data TLB miss handler more verbose.
