(mounting still only works from the Terminal).
* Shuffled functions in node_monitor.cpp around to clearly differentiate between
private, private kernel, and public kernel functions.

before another one in the list.
* The video modes in the boot loader are now sorted (by resolution, larger
resolution comes first). Doubled entries are automatically removed; this
fixes bug #192.

action has been set for the signal. If so, it doesn't try to install a
debugger, but simply lets the caller deliver the signal.
Fixes bug #237 (VLC entering the debugger when checking for processor
extensions).

modified to panic when an invalid block is requested (to find fs errors)

* Fixed broken "full sem" mechanism.
* Fixed recycling of previously mapped IO space chunks. Should avoid the
panic() call earlier introduced by Marcus.
(tracked down by axeld and bonefish over the course of three days
(in between skiing) and finally nailed on the bus back home)

the device manager is initialized. For x86 it does nothing, but
for PPC it searches for a supported interrupt controller and
remembers it for later use.
arch_int_{enable,disable}_io_interrupt() are implemented as
well as handling of external exceptions (aka as I/O interrupts).
We'll see later how well that works.

returns the root device node. Now its actually possible to
traverse the device node tree without a node to start with.
* Fixed execution order problem in dm_get_next_child_node(). The
supplied node was put first (which could cause its immediate
deletion), but was still accessed thereafter.

time of the idle thread as a measure, we now compute the CPU activity on
each thread switch - the time the CPU worked is the total of user and kernel
time a thread spent during its quantum.
Unlike before, this mechanism works correctly on SMP machines. I hope this
works as expected :)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16193 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added syscalls _kern_set_cpu_enabled() and _kern_cpu_enabled().
* scheduler.c::sRunQueue::tail was not maintained at all; changed sRunQueue to
be a simple thread pointer instead of a struct thread_queue.
* Turns out we're monitoring CPU activity incorrectly when we've got more
than one CPU.
* Renamed the global CPU array from "cpu" to gCPU.

synchronization as done in init_mtrrs() failed because of that (let the system
hang).
Unfortunately, MTRR still doesn't work on my dual PIII with SMP enabled; that
was just one reason it didn't work.

The test application lets run a thread at the highest priority that calls
yield all the time - the system stays responsible when it runs, so it seems
to work fine :)
Changed the malloc implementation to use _kern_thread_yield() instead of
snoozing.
We should think about making this call public, too.

enqueueing a thread to the run queue.
This mechanism is now used for the thread priority boost on semaphore
release. Also, those threads are no longer made real time threads, they
now get a temporary priority of B_FIRST_REAL_TIME_PRIORITY - 1.

It now works fine on my P4 system as well :-)
But since the BIOS area is not identity mapped, it might work on fewer systems
than it does in BeOS R5.

on at least one of my systems, it only works on 3 of them...).
* Added APM safemode setting.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16152 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Added a thread priority column to the thread list.
* Added "realtime" command that lists all real-time threads.

* cached_block::parent_data can be NULL in a sub transaction in case the
block wasn't part of the parent transaction (but not in low memory
situations). cache_abort_sub_transaction() and cache_detach_sub_transaction()
didn't account for this, though, ie. the block data could end up
corrupted.
* Renamed cached_block::original in original_data.
* Renamed cached_block::data in current_data.
* Added some comments.

cache_abort_sub_transaction now doesn't crash if parent_cache is NULL (happens in low memory situations)
Axel, please review and fix if needed

the boot loader into the kernel (renamed to of_get_next_device()).

* BEntry::Remove() now uses _kern_remove_dir() for directories.
* Added fd parameter to _kern_remove_dir().
* Fixed LibBeAdapter's _kern_unlink() to only work on files, and
added _kern_remove_dir() for directories.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16078 a95241bf-73f2-0310-859d-f6bbb57e9c96
* exchanged sBlueScreenEnabled and sBlueScreenOutput (so that they better
match the sSerialDebugEnabled and sSyslogDebugEnabled variables).

can now safely unmount volumes that are still in use by some applications.
Minor fixes to the FD disconnection implementation:
* put_fd() checked the condition for being able to disconnect a descriptor
incorrectly (causing the FD to never be disconnected).
* remove_fd() would hand out disconnected descriptors (but should have
returned NULL for them).

code. The stack pointer was not adjusted, hence we were
overwriting the previous register value. But it looks like I
missed to check in the arch_cpu.h with the iframe structure
including the floating point registers anyway.
* Backported the ELF PPC relocation code from the boot loader to
the kernel.
* Fixed the PPC version of arch_thread_switch_kstack_and_call().
Apparently the signature had changed, but the assembly
implementation was not adjusted accordingly.
* sc prints more registers now (LR, CR, CTR, XER,...).
* Fixed several occurences of not-working fault handlers.
Apparently the compiler realized, that the "error" label was
never jumped to (by the code it knew), and optimized the
respective code away. Now we use a trick to make it think the
error label might actually be jumped to. I wonder whether the
x86 version has the same problem when being compiled with GCC4.
* Adopted the x86 page fault handling interrupt code.
