1187 6620 d 6 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
 
1186 6620 d 7 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1185 6620 d 9 h jermar /kernel/trunk/ Add task_create_arch() for all architectures.  
1184 6620 d 9 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.
 
1172 6621 d 13 h palkovsky /kernel/trunk/arch/amd64/src/proc/ Comment update.  
1171 6621 d 14 h jermar /kernel/trunk/ Initialize ARCH_THREAD_DATA on all architectures.
On ia32 and amd64 this fixes bug caused by uninitialized TLS pointer.
 
1121 6641 d 2 h jermar /kernel/trunk/ Small textual changes.  
1119 6641 d 2 h palkovsky /kernel/trunk/arch/ Fixed bad rflags masking in amd64.
Added TLS get address instruction emulation for mips.
 
1112 6641 d 13 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1104 6642 d 6 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.
 
1102 6643 d 1 h palkovsky /kernel/trunk/arch/ Keep $K1 register for use as a thread local storage pointer on MIPS.  
1100 6644 d 3 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.
 
1094 6644 d 12 h palkovsky /kernel/trunk/ Allowed saving less registers.  
1078 6647 d 5 h jermar /kernel/trunk/ Improved uspace threads.
ia64 needs fixing.
 
1077 6647 d 10 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1074 6647 d 11 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1072 6647 d 12 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1066 6647 d 22 h jermar /kernel/trunk/ Support for user space threads.  
1064 6647 d 23 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6647 d 23 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1060 6648 d 2 h palkovsky /kernel/trunk/ Added task_print.
Fixed ipc to support connect_me_to.
 
1052 6648 d 7 h decky /kernel/trunk/arch/amd64/src/boot/ fix wrong structure members size assumption  
1051 6648 d 7 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6648 d 7 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1039 6648 d 11 h decky /kernel/trunk/arch/ update for the use of more init tasks  
1037 6648 d 12 h decky /kernel/trunk/ support for more init tasks
(might break some archs yet)
 
1021 6649 d 5 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.
 
1004 6649 d 22 h decky /kernel/trunk/ ppc32: basic exception and interrupt handling  
959 6651 d 2 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6651 d 3 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.
 
955 6651 d 4 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
938 6652 d 5 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
906 6661 d 23 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 6664 d 23 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 6665 d 6 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.

822 6684 d 0 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
820 6684 d 1 h jermar /kernel/trunk/ Convert size_t, count_t and index_t to 64-bits on 64-bit architectures.
Change some pfn_t usages to count_t, size_t and index_t.
 
814 6684 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
