Added syscall that lets kernel regain access to keyboard.

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.

Update page fault handlers to distinguish between different access modes that had caused the page fault.
1411
6635 d 11 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.

Do not report possible deadlock on fb_lock.
This issue was causing troubles in connection
with slow framebuffer in simulated environment
when false positives triggered an infinite
recursion of attempts to report deadlock on
fb_lock using printf() and fb_putchar().

/kernel/trunk/arch/ia32/src/drivers/
Fix number of frames allocated for VESA frame buffer in the singular
case when the frame buffer size is below FRAME_SIZE.

Change coding style in vesa.c and do some minor changes.

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

VESA detection failure fix.
(Some headers)

Amd64 framebuffer
1288
6654 d 16 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.

ia32 VESA FB support

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.
1261

/kernel/trunk/arch/
Fixes in amd64 and ia32 ddi_iospace_enable_arch().
1258
6660 d 6 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
6660 d 13 h

Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
1255
6660 d 16 h
jermar
/kernel/trunk/arch/
I/O Permission bitmap fixes. The trailing all-one sequence must be 8 bits long.
Update TSS limit in a proper way.
1251
6661 d 13 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.

This patch enables 32 base of GDT on APs at boot. It should now be able to use GDTs allocated up of 16MB so I hope this patches AP crash bug ocurred in some memory configurations.

SYS_AS_AREA_SHARE_PERFORM syscalls.

Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().

Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.

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.

Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
