1184 6653 d 7 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.		  
1171 6654 d 13 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.		  
1121 6674 d 0 h jermar /kernel/trunk/ Small textual changes.  
1119 6674 d 0 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.		  
1112 6674 d 11 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).		  
1106 6674 d 23 h jermar /kernel/trunk/arch/ Pass either -DCONFIG_PAGE_PT or -DCONFIG_PAGE_HT to the compiler.  
1104 6675 d 4 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.		  
1100 6677 d 1 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
1078 6680 d 3 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.		  
1077 6680 d 8 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1074 6680 d 10 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1070 6680 d 11 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6680 d 20 h jermar /kernel/trunk/ Support for user space threads.  
1059 6681 d 2 h jermar /kernel/trunk/ Clear user address space when creating new page tables.
Fix mapping of l_apic and io_apic on amd64.		  
1037 6681 d 10 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)		  
1024 6682 d 3 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.		  
1021 6682 d 4 h jermar /kernel/trunk/ Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time.		  
1019 6682 d 5 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
1016 6682 d 7 h jermar /kernel/trunk/arch/ia32/src/ Improved ia32 interrupt handlers.  
1008 6682 d 9 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.		  
984 6683 d 6 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6683 d 7 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6683 d 11 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6684 d 1 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.		  
958 6684 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 6684 d 2 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
955 6684 d 2 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6684 d 5 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
940 6685 d 3 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.		  
938 6685 d 3 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
925 6685 d 12 h palkovsky /kernel/trunk/arch/ia32/src/mm/ Fix e820list on ia32.  
910 6692 d 8 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6694 d 21 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		  
897 6697 d 22 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.		  
894 6698 d 4 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
893 6698 d 9 h jermar /kernel/trunk/arch/ sparc64 work.
Revive OFW console code and use it before the kernel switches to standalone console.
