kernel/int: consolidate interrupt vector number to `int32`

This is no-op for 32 bit platforms because `int32` is defined as `long` there.

Change interrupt vector number from 64 bits to 32 bits for 64 bit platforms.

kernel: Rewrite B_DEBUG_SPINLOCK_CONTENTION.

* Replace count_low/count_high with bigtime_t fields plus an int32.
sizeof(spinlock) is now 32 bytes with the debug option enabled.

* Adjust and clean up all spinlock code to use the new fields.

* Fold DEBUG_SPINLOCK_LATENCIES into the new code. Remove the bootloader
option and other flags for it (these were not compiled in by default.)

The new code should be much easier to understand and also more powerful.
However, the information transmitted to userland isn't as useful now;
the KDL command output will have the interesting information.

(Things could be reworked to transmit more interesting information to
userland again if desired, but as this code clearly hadn't been compiled
for many years, as it referred to global spinlocks that have been gone
for a very long time.)

OS: Rename B_USER_CLONEABLE_AREA to B_CLONEABLE_AREA.

It now lives in OS.h. The idea is that this will now be
accessible to userland applications, so userland memory
is protected from access by other processes, just as
kernel memory is.

No functional change (the constants are still the same,
though I've changed some to use shifts to make clear
which bits are allocated are which are unused.)

map_physical_memory()'s physicalAddress parameter type from void* to

BeOS.
* Adjusted all code using the affected interfaces (Oh what fun!). Added a few

are used). Looks like quite a few drivers aren't 64 bit safe and others
will break with PAE.

* Introduce a (private) flag B_NO_HANDLED_INFO for install_io_interrupt_handler.
It causes the interrupt handler to be inserted at the very end of the list
instead of at the top. It is intended to be used as a workaround when a
interrupt handler cannot know if it actually handled the interrupt. This
should never be used by native drivers. Also if we know that the result is
not valid because of this flag we won't disable the vector in case we count
many unhandled interrupts as those numbers are then unreliable.
* Moved B_NO_LOCK_VECTOR to be a private flag as well.
* Made the interrupt handler list a simple manually maintaned singly linked list
instead of the doubly linked one used with insque and remque as it greatly
simplifies things for such an easy use case and is more compact.

* Change the signature of add_debugger_command()/remove_debugger_command() on

B_DEBUG_SPINLOCK_CONTENTION is defined to 1. It typedefs spinlock to a

Introduce a B_NO_LOCK_VECTOR flag to be used with install_io_interrupt_handler().
When specified it desigantes that the interrupt handler should not lock the
vector with a spinlock when executing the installed interrupt handlers. This
is necessary to allow the same interrupt vector to be handled in parallel on
different CPUs. And it is required for the CPU halt to work synchronously when
there is more than one AP CPU. Though the acquire_spinlock() should cause IPIs
to be processed, only this fixed the SMP_MSG_FLAG_SYNC problem for me.
Not locking is safe as long as it is guaranteed that no interrupt handler is
registered or removed while the interrupt handler is running. We can guarantee
this for the SMP interrupt handlers we install in arch_smp_init() as they are
never uninstalled. Probably this flag should be made private though.
Restored the SMP_MSG_FLAG_SYNC when entering the kernel debugger.

yet another fix for #1018, which has at this point blossomed into a reorg of how AP cpus are initialized.
the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
(though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
"status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
equivalent (and private) are_interrupts_enabled()

the previously added IO interrupt handling routines are no longer necessary, at least for now.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@21046 a95241bf-73f2-0310-859d-f6bbb57e9c96

added io_interrupt_handler methods for dynamic handling of IO interrupts, including enabling/disabling without allocation and in interrupt context.

yet another fix for #1018, which has at this point blossomed into a reorg of how AP cpus are initialized.
the new cpuid stuff was apparently exacerbating an existing problem where various bits of low level
cpu code (specifically get_current_cpu) weren't really initialized before being used. Changed the
order to set up a fake set of threads to point each cpu at really early in boot to make sure that at
all points in code it can get the current 'thread' and thus the current cpu.
A probably better solution would be to have dr3 point to the current cpu which would then point to the
current thread, but that has a race condition that would require an int disable, etc.

added the format expected by panic to throw warnings on compilation

- moved dumpBlock() into debug.c, renamed it to dump_block() and added it
to kernel-exports.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18268 a95241bf-73f2-0310-859d-f6bbb57e9c96

Applied some changes suggested by mmu_man, more to come, though:
- has_signals_pending() is not declared in Be headers, and it isn't declared in
our KernelExport.h anymore, too
- removed snooze_etc() from KernelExport.h, as it's already defined in OS.h
(and really exported by libroot.so).

{install|remove}_io_interrupt_handler() now correctly handle the B_NO_ENABLE_COUNTER flag.
Lots of cleanup:
- moved B_NO_ENABLE_COUNTER flag definition out of int.h to KernelExport.h, as it's
described in the BeBook (although it's probably not really used that often :))
- int.c no longer has any platform dependent code (+ 0x20 on interrupt numbers is gone);
it's now entirely handled in the arch/x86/ section.
- the io_vectors[] is now statically initialized, instead of allocated from the heap
- removed {install|remove}_interrupt_handler(); they weren't that useful, arch_smp_init()
is now calling install_io_interrupt_handler() correctly instead
- introduced a new arch_int.h header file that currently contains NUM_IO_VECTORS only
(though on x86, it also has ARCH_INTERRUPT_BASE == 0x20).
- changed the return type from {install|remove}_io_interrupt_handler() from "long" to
"status_t"
- rearranged and cleaned the PIC initialization code, made the PIC code more prominent
- changed comments that talk about a non existing 8239 (the PIC chip is actually 8259)
- moved arch/x86/interrupts.h to the source directory, as it's not used outside
- added BeOS compatible interrupts_enabled() function, that should replace our
equivalent (and private) are_interrupts_enabled()

Added B_USER_CLONEABLE_AREA protection flag. Here it does belong.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@11048 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved B_KERNEL_{READ|WRITE_AREA} from vm_types.h to KernelExport.h.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@10425 a95241bf-73f2-0310-859d-f6bbb57e9c96

Moved the user_memcpy()/strlcpy()/memset() calls to KernelExport.h.

spawn_kernel_thread() now matches the spawn_thread() prototype - there
is no reason for them to be different.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7909 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed the prototype of parse_expression() - it's parameter should be const.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7840 a95241bf-73f2-0310-859d-f6bbb57e9c96

daemon_hook typedef wasn't R5 compatible.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@7627 a95241bf-73f2-0310-859d-f6bbb57e9c96

Fixed a missing const.

Forgot to commit these... Should fix network stuff build issues.
Add again the load_driver_symbols() export into our KernelExport.h, as it's expected
by many kernel add-ons (drivers, modules)... the network ones, for a start.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2672 a95241bf-73f2-0310-859d-f6bbb57e9c96

Our new KernelExport.h header.
Typedefs for debugger and kernel daemon hooks, cleaned up.
Added a ToDo item about the "abuse" of the quent structure.


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@2581 a95241bf-73f2-0310-859d-f6bbb57e9c96

*LOTS* of small changes to make the kernel compatible with Be's KernelExport.h

modified to provider better R5 compatibility


git-svn-id: file:///srv/svn/repos/haiku/trunk/current@1615 a95241bf-73f2-0310-859d-f6bbb57e9c96

Source compatibility objective: time to add some BeOS specific public headers.
