paging_start counting fix on ia64
922
6773 d 10 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
6773 d 15 h
jermar
/kernel/trunk/arch/ia64/
ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
919
6773 d 19 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
6775 d 21 h
jermar
/kernel/trunk/arch/ia64/src/
ia64 work.
Support switch from userspace register stack in heavyweight handler.
915
6775 d 22 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
6777 d 12 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
6777 d 16 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
6777 d 19 h
bondari
/kernel/trunk/
ELF framework for all archs. SPARC V9 not tested to compile.
909

907
6779 d 20 h
palkovsky
/kernel/trunk/generic/src/proc/
Correct sleeping on memory allocation during FPU lazy switch.
906
6780 d 8 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
