811 6685 d 19 h jermar /kernel/trunk/ Fix number of steps in softint division.
Make ia64 port compile with softint.		  
810 6686 d 0 h cejka /kernel/trunk/genarch/ Added softint for emulation 32 and 64 bit division.
Not tested yet.		  
809 6686 d 0 h palkovsky /kernel/trunk/arch/amd64/src/smp/ Simics GS patch even in SMP.  
808 6686 d 6 h palkovsky /kernel/trunk/arch/amd64/ Doc updates.  
807 6686 d 6 h palkovsky /kernel/trunk/arch/amd64/src/boot/ I'm unsure if simics is broken or the only one according to spec,
but SYSCALL now works even with simics.		  
806 6686 d 13 h palkovsky /kernel/trunk/arch/amd64/ Added (finally!) userspace to AMD64.
It does not work on Simics *$U&%&$&*#. Broken simics!!!
There should be probably LEA instead of MOV/ADD, but LEA does not
work in neither qemu nor bochs. Any other simulator to test? :-/		  
805 6686 d 13 h palkovsky /uspace/trunk/ Added AMD64 userspace.  
804 6686 d 14 h cejka /uspace/trunk/softfloat/ 32 bit float division added.
Some small bugs fixed.
Code cleanup.		  
803 6686 d 15 h palkovsky /kernel/trunk/arch/amd64/ Basic amd syscall support.  
802 6686 d 17 h palkovsky /kernel/trunk/arch/amd64/ Userspace now starts executing correctly.  
801 6686 d 17 h palkovsky /boot/trunk/arch/amd64/ Copy init to amd boot loader.  
800 6686 d 18 h palkovsky /kernel/trunk/arch/amd64/include/ Split AMD interrupt.h from ia32 version.  
799 6686 d 18 h palkovsky /kernel/trunk/ Preliminary work on AMD userspace.  
798 6686 d 18 h decky /kernel/trunk/arch/amd64/src/boot/ fix init_addr virtual address  
797 6686 d 21 h palkovsky /kernel/trunk/arch/mips32/ Fixed uspace address constants.  
796 6686 d 22 h palkovsky /kernel/trunk/ Gxemul support for mips userspace. MIPS now _must_ be started
always with userspace, there is (almost) no way how to pass parameters
to kernel.		  
795 6686 d 23 h palkovsky /uspace/trunk/ Modifiaction to make mips userspace work.  
794 6686 d 23 h palkovsky /kernel/trunk/ Added MIPS userspace. Currently can't make it work in gxemul.  
793 6687 d 0 h jermar /kernel/trunk/ Use hash_table_get_instance instead of list_get_instance.
Rename page_operations to page_mapping_operations.
Rename page_pt_operations to pt_mapping_operations.
Rename page_ht_operations to ht_mapping_operations.		  
792 6687 d 1 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.		  
791 6687 d 13 h palkovsky /kernel/trunk/generic/ better utilization of memory in slab alloc
removed malloc-8 slab		  
790 6687 d 17 h jermar /kernel/trunk/ Generic chaining hash table.  
789 6687 d 17 h palkovsky /kernel/trunk/generic/ Early SLAB initialization, the cpu-cache is initialized later.
If you want to use slab_cache_create befor slab_cpu_enable, add
a flag SLAB_CACHE_MAGDEFERRED.		  
788 6687 d 21 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
787 6687 d 22 h palkovsky /kernel/trunk/generic/ Added constructor/destructor calls to SLAB.
Changed allocation of thread_t structure to use SLAB.		  
786 6687 d 23 h bondari /kernel/trunk/ frame_alloc() functions variations in order to avoid problems with frame_alloc_generic() changes.
IMPORTANT: Parameter order for frame_alloc() was changed		  
785 6688 d 0 h jermar /kernel/trunk/generic/src/ Comments clarification.  
784 6688 d 1 h palkovsky /kernel/trunk/generic/src/proc/ Cleanup of scheduler code  
783 6688 d 1 h palkovsky /kernel/trunk/generic/ Fixed some typos in slab allocator.
Scheduler now has better algorithm on load balancing.
Unfortunately it reveals deadlock in slab allocator :-/		  
782 6688 d 3 h palkovsky /kernel/trunk/generic/src/mm/ Small locking performance tweak.  
781 6688 d 14 h palkovsky /kernel/trunk/generic/ Still better locking - does not hold global spinlock when
destroying cache.		  
780 6688 d 18 h palkovsky /kernel/trunk/ Small fix in slab allocator for large-sized slabs.  
779 6688 d 18 h jermar /kernel/trunk/generic/ Simplify load balancing activation.
This in fact removes the livelock that prevented cpu_sleep() to be called in SMP systems.		  
778 6688 d 20 h palkovsky /kernel/trunk/ Fixed boot process not to call malloc when slab not initialized.
Added simics workaround.		  
777 6688 d 21 h palkovsky /kernel/trunk/generic/ added thread list to kconsole.  
776 6689 d 0 h palkovsky /kernel/trunk/generic/ Added more granular locking to slab allocator and thus fix
hopefully last race condition.		  
775 6689 d 1 h palkovsky /kernel/trunk/generic/ Added scheduler queues output. The scheduler is buggy - on SMP
the cpus never get tu cpu_sleep, in slab2 test on 4 cpus everything
is on the first cpu.
The slab allocator passes tests in this configuration, but in slightly
different(more efficient) locking order it panics. TODO: Find out why
does it panic.		  
774 6689 d 3 h palkovsky /uspace/trunk/ Allow ia32 native compiler for uspace.  
773 6689 d 13 h palkovsky /kernel/trunk/ Added slab stress test.
Fixed race condition in slab allocator.
Moved initialization of slab to the point where we know correct config.cpu_count
Correctly passes tests on amd64, ia32 in both bochs & qemu.		  
772 6689 d 14 h palkovsky /kernel/trunk/ Fixed non-initialized cpu-cache.
