958	6714 d 1 h	jermar	/kernel/trunk/	Nicer ia32 interrupt handlers and structures holding interrupted context data. Unify the name holding interrupted context data on all architectures to be istate.
957	6714 d 1 h	decky	/kernel/trunk/arch/	run ppc32 kernel above 2 GB
955	6714 d 1 h	palkovsky	/kernel/trunk/	Added kernel IPC functionality.
952	6714 d 5 h	jermar	/kernel/trunk/	Support for loading segments containing .bss section.

947	6714 d 10 h	vana	/kernel/trunk/	Better purge page selection.
946	6714 d 22 h	jermar	/kernel/trunk/generic/	Fix frame deallocation. Zone state is to be upadated only when the frame refcount reaches zero.

944	6715 d 0 h	vana	/kernel/trunk/	Itanium tlb_invalidate_pages
941	6715 d 2 h	palkovsky	/kernel/trunk/	Fixed mips elf loading.
940	6715 d 2 h	jermar	/kernel/trunk/	Get rid of unneeded macros. Their functionality has been replaced by the ELF loader.
939	6715 d 2 h	palkovsky	/kernel/trunk/contrib/conf/	Fix msim configuration.
938	6715 d 2 h	jermar	/kernel/trunk/	Basic support for loading ELF object files. ia64, amd64, ia32 working. mips32 requires some attention.
935	6715 d 3 h	vana	/kernel/trunk/	Two frame stack (standard stack + RSE) on Itanium
934	6715 d 3 h	decky	/kernel/trunk/arch/ppc32/	remove all OpenFirmware bindings from ppc32 kernel code kernel now runs in real mode (ppc32)
932	6715 d 4 h	palkovsky	/kernel/trunk/generic/src/console/	Allow using direct address as parameter.
931	6715 d 4 h	palkovsky	/kernel/trunk/generic/src/console/	Allow direct address specification.
930	6715 d 6 h	decky	/kernel/trunk/contrib/conf/	preliminary Simics 3.0 configuration for Simics
929	6715 d 7 h	palkovsky	/kernel/trunk/	Restrict itanium test to itanium.
928	6715 d 7 h	vana	/kernel/trunk/	Itanium tlb_invalidate_all
927	6715 d 9 h	decky	/kernel/trunk/contrib/conf/	Simics 3.0 IA32/AMD64 component configuration
925	6715 d 11 h	palkovsky	/kernel/trunk/arch/ia32/src/mm/	Fix e820list on ia32.
924	6715 d 12 h	palkovsky	/kernel/trunk/arch/mips32/	Macro redefinition for mips fpu.
923	6715 d 20 h	vana	/kernel/trunk/arch/ia64/src/	paging_start counting fix on ia64
922	6717 d 22 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	6718 d 3 h	jermar	/kernel/trunk/arch/ia64/	ia64 work. Userspace is now working. There is an unrelated show stopper, however.
919	6718 d 8 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	6720 d 10 h	jermar	/kernel/trunk/arch/ia64/src/	ia64 work. Support switch from userspace register stack in heavyweight handler.
915	6720 d 11 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	6722 d 0 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	6722 d 4 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	6722 d 7 h	bondari	/kernel/trunk/	ELF framework for all archs. SPARC V9 not tested to compile.
909	6722 d 10 h	bondari	/kernel/trunk/generic/include/	elf32 complete headers
907	6724 d 9 h	palkovsky	/kernel/trunk/generic/src/proc/	Correct sleeping on memory allocation during FPU lazy switch.
906	6724 d 20 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	6724 d 22 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	6725 d 1 h	jermar	/kernel/trunk/arch/ia64/src/mm/	ia64 fix in page.c == (comparison) was used istead of = (assignment).
903	6725 d 3 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	6726 d 8 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	6726 d 10 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.
