Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.

task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.

Update page fault handlers to distinguish between different access modes that had caused the page fault.
1411
6700 d 4 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.

zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas.

/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.

Added means to make a simple action upon interrupt.
1278

Changed interrupt_control to preemption_control.

When seting TSS limit, take the mandatory extra ending byte with all bits set into account.
Align this group of eight bits on byte boundary.

Fixes in amd64 and ia32 ddi_iospace_enable_arch().
1258
6724 d 23 h
palkovsky
/kernel/trunk/
Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.
1257

Initialize amd64 and ia32 task iomapver generation counter.
1256

Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
1255

I/O Permission bitmap fixes. The trailing all-one sequence must be 8 bits long.
Update TSS limit in a proper way.

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.

Same 24 - > 32 bit lgdt patch on amd64 arch. Now both ia32 and amd64 platforms are able to have AP GDTs in all lowest 4GB of physicall memory.

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.
