Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
938
6771 d 8 h
jermar
/kernel/trunk/
Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.

Two frame stack (standard stack + RSE) on Itanium
934

paging_start counting fix on ia64
921
6774 d 9 h
jermar
/kernel/trunk/arch/ia64/
ia64 work.
Userspace is now working.
There is an unrelated show stopper, however.
919
6774 d 14 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
6776 d 16 h
jermar
/kernel/trunk/arch/ia64/src/
ia64 work.
Support switch from userspace register stack in heavyweight handler.
915
6776 d 16 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

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
6778 d 10 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

bondari
/kernel/trunk/
ELF framework for all archs. SPARC V9 not tested to compile.
906
6781 d 2 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
6781 d 7 h
jermar
/kernel/trunk/arch/ia64/src/mm/
ia64 fix in page.c
== (comparison) was used istead of = (assignment).
903
6781 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
6782 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
6782 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
6783 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
6783 d 10 h
jermar
/kernel/trunk/arch/
ia64 work.
Add dummy TLB fault handlers.
Improve code reuse in arch/mm/tlb.c.
898

Minor changes.
897
6784 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.
895
6784 d 6 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
6784 d 9 h
jermar
/kernel/trunk/
Move i8042 driver to genarch as it might be used by more architectures.
893
6784 d 14 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.
