Function for destroying address space for which there is no other reference in the kernel.

Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.

/kernel/trunk/
Update page fault handlers to distinguish between different access modes that had caused the page fault.
1411
6652 d 22 h
jermar
/kernel/trunk/
Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.

Amd64 framebuffer

6672 d 3 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.

Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
1251

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

Added uspace call to enable/disable interrupts.
1203
6689 d 23 h
jermar
/kernel/trunk/arch/
Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
1201
6689 d 23 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.

6693 d 22 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
6693 d 23 h
jermar
/kernel/trunk/arch/
Replace assembly from pm.c with new inline functions defined in asm.h.
1184
6694 d 1 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.
