930 6638 d 2 h decky /kernel/trunk/contrib/conf/ preliminary Simics 3.0 configuration for Simics  
929 6638 d 2 h palkovsky /kernel/trunk/ Restrict itanium test to itanium.  
928 6638 d 3 h vana /kernel/trunk/ Itanium tlb_invalidate_all  
927 6638 d 4 h decky /kernel/trunk/contrib/conf/ Simics 3.0 IA32/AMD64 component configuration  
925 6638 d 6 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
924 6638 d 7 h palkovsky /kernel/trunk/arch/mips32/ Macro redefinition for mips fpu.  
923 6638 d 15 h vana /kernel/trunk/arch/ia64/src/ paging_start counting fix on ia64  
922 6640 d 18 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 6640 d 22 h jermar /kernel/trunk/arch/ia64/ ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.		  
919 6641 d 3 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 6643 d 5 h jermar /kernel/trunk/arch/ia64/src/ ia64 work.
Support switch from userspace register stack in heavyweight handler.		  
915 6643 d 6 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 6644 d 20 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 6645 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 6645 d 3 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
909 6645 d 5 h bondari /kernel/trunk/generic/include/ elf32 complete headers  
907 6647 d 4 h palkovsky /kernel/trunk/generic/src/proc/ Correct sleeping on memory allocation during FPU lazy switch.  
906 6647 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		  
905 6647 d 18 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 6647 d 21 h jermar /kernel/trunk/arch/ia64/src/mm/ ia64 fix in page.c
== (comparison) was used istead of = (assignment).
