924 6642 d 8 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6642 d 16 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
922 6644 d 19 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 6644 d 23 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
920 6645 d 0 h jermar /uspace/trunk/libc/arch/ia64/ Rewrite syscall wrapper in assembly.  
919 6645 d 4 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.		  
918 6645 d 4 h jermar /boot/trunk/ ia64 work.
Changes to make userspace work (boot part).		  
917 6645 d 4 h jermar /uspace/trunk/libc/arch/ia64/ ia64 work.
Changes to make userspace work (uspace part).		  
916 6647 d 6 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6647 d 7 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.		  
914 6647 d 8 h decky /boot/trunk/arch/ppc32/loader/ flush caches  
913 6647 d 9 h decky /boot/trunk/arch/ppc32/loader/ ppc bootstrap almost working  
912 6648 d 21 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 6649 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 6649 d 4 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6649 d 6 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
908 6651 d 3 h jermar /uspace/trunk/ Start ia64 uspace.  
907 6651 d 5 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6651 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 6651 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.
