1292 6623 d 5 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6623 d 7 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6623 d 8 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1287 6623 d 10 h vana /kernel/trunk/ ia32 VESA FB support  
1256 6629 d 5 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
 
1251 6630 d 6 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.
 
1212 6636 d 2 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6641 d 4 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
 
1201 6641 d 5 h jermar /kernel/trunk/arch/ Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit.
 
1187 6645 d 3 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 6645 d 4 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1184 6645 d 6 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.
 
1112 6666 d 10 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1104 6667 d 3 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 6669 d 0 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.
 
1077 6672 d 7 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1074 6672 d 8 h palkovsky /kernel/trunk/ Ported AMD64 debugger to ia32 and enabled AS watchpoint to ia32 as well.  
1070 6672 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1066 6672 d 19 h jermar /kernel/trunk/ Support for user space threads.  
1024 6674 d 1 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1019 6674 d 4 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
984 6675 d 5 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6675 d 6 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6675 d 10 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
958 6676 d 0 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 6676 d 0 h decky /kernel/trunk/arch/ run ppc32 kernel above 2 GB  
955 6676 d 1 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
952 6676 d 4 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
940 6677 d 1 h jermar /kernel/trunk/ Get rid of unneeded macros.
Their functionality has been replaced by the ELF loader.
 
938 6677 d 2 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.
 
910 6684 d 7 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
906 6686 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
 
894 6690 d 3 h jermar /kernel/trunk/ Move i8042 driver to genarch as it might be used by more architectures.  
860 6696 d 20 h decky /kernel/trunk/ indentation changes
ppc32 fpu context save/restore
ppc32 CPU version
ppc32 memcpy
 
854 6698 d 2 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
832 6706 d 22 h jermar /kernel/trunk/ Change pt_mapping_remove() to deallocate frames for empty PTL1, PTL2 and PTL3.  
831 6707 d 4 h jermar /kernel/trunk/ Make use of one unused bit in PTE formats of amd64, ia32 and mips32 to store 1 in valid mappings.
This helps to distinguish valid entries from not present entries with 0 content (i.e. not present
entries with PFN 0 and other bits cleared).
 
825 6708 d 3 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
823 6708 d 21 h jermar /kernel/trunk/ Reimplement ASID stealing logic.
This time, hopefully, with correct synchronization.
 
814 6709 d 8 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
