a090257d09 Add volatile keyword to apic memory access, cleanup, add timeout to arch_smp_send_ici.
But this still doesn't help with bug #1018...

1cbf8f4b3c initial support for a commpage, which is a chunk of memory in high kernel space with user readonly permissions.
The first use is to let the kernel decide what the preferred syscall mechanism is at boot time and copy the
appropriate user space code there. Can be used for routines the kernel can decide best how to use (memcpy, some
timing routines, etc).

badc7b674e 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.

dfb5375d18 clean up TSS initialization.
Now two complete tss structures exist within the per-cpu structure. Instead
of having to create a seperate area per each one, initialize them in place.
Also, the old mechanism to getting all of the cpus to get initialized was 
subtly broken, but still managed to work. Now, just force all the cpus to
initialize at boot, which makes the actual swapping of esp0 somewhat simpler.

dcdc4f4b43 pulled over some stuff from newos:
at boot, per cpu, detect the cpu, pull down all the relevant cpuid bits and
save them into the per-cpu structure. Changed most of the code scattered here
and there that reads the cpuid to use a new api, x86_check_feature, which looks
at the saved bits.
Also changed the system_info stuff to read from these bits.
While i was at it, refreshed all the bits to be current.

some Pentium 200 MMX pretend to support MTRRs.

fa4858af26 Didn't notice that x86_enter_userspace() also copied the thread entry's arguments to
the userland stack in an unsafe way - moved that stuff to arch_thread_enter_userspace(), too.

8fc075ac5c * There was no reason to copy the "userland calls exit_thread()" stub with interrupts
turned off - accessing userland memory. Now, arch_thread_enter_userspace() does that
  job, and as a result, may also fail.
* dump_thread() now directly prints the info of the current thread when used without
  argument (rather than iterating the thread list to look for the current thread).
* If arch_thread_init_tls() fails upon thread creation, the function will now return
  an error.

d51ce54011 * Added the opportunity to add temporary debug interrupt handlers for
arch dependent code (they will be removed as soon as someone else
  asks for these interrupt lines).
* Added an interrupt driven keyboard handler to the kernel that uses
  this technique. As a result, you can now press F12 to enter the kernel
  debugger before the input_server has been started, and Control-Alt-Delete
  should reboot the system (actually I did not test the latter yet).

f4b0f67cf6 Added [arch_]int_post_device_manager() which is invoked after
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.

7afc16f059 * Fixed a bug regarding storing/restoring FPSCR in the interrupt
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.

ba61df6d0b Beginnings of APM support: we now connect to the APM BIOS in 32 bit protected mode.
We don't do anything with it yet, though, so the BIOS will probably ignore us since
we are supposed to poll for events.

6c678c57c7 * The exception vector offset is now also part of the iframe.
* Cloned iframe stack management from x86.
* Reimplemented arch_thread_{get,set}_current_thread(). The
  thread structure is stored in SPRG2. It is set to NULL in
  arch_cpu_preboot_init(), now. A non-null current thread
  causes all kinds of undesired behavior in early boot code.
* We establish the address space mappings we know from the
  Open Firmware as areas. At least those in kernel address
  space. The ones in userland address space are tougher.
  Fortunately on my Mac mini there aren't any save the
  boot_loader stack, which is not needed any longer anyway.
* Added stack trace support to the kernel debugger. Mostly
  cloned and adjusted the x86 code. Some bits are still
  missing, like stack traces for other threads.

7176dd57e5 Reworked the exception handling code. The former one ran into the
void after turning off BAT for the segment containing itself.
The monster macro for the exception vector code was not really
elegant besides being too long for the 32 byte performance
monitor exception slot. Furthermore wasting three of the SPRG*
registers as cheap scratch memory wasn't that nice either.

We now have a three-step approach: The exception vectors
themselves contain only five instructions which branch to common
code at the beginning of the same physical page. That one sets
up BAT for itself, turns address translation back on and jumps
into the kernel. There we turn off BAT again, dump an iframe,
and enter the actual exception handler (/dispatcher). Upon return
the registers are restored from the iframe and we get back to the
place where the exception occurred.

262e0a636b We use the same strategy for computing the system time as on x86 now.
The time base conversion factor is the 32 bit value
  2^32 * 1000000 / time base frequency,
so the system time can be computed by
  system time = time base * conversion factor / 2^32.
The expression in system_time() looks more complicated now, but is
actually much faster (factor 2.5 on my Mac mini). I'm positively
surprised, how good the assembly looks, that GCC 4 generates. There's
not that much potential for optimization by hand-coding the function.

e55e1a0e66 Implemented the PPC specific RTC support. We search for an "rtc"
device in the Open Firmware implementation of boot loader and
pass its path to the kernel, where it's opened and used for
getting/setting the real time. The expensive atomic_*64() on PPC
32-bit make things a bit more complicated. Moreover, missing
64 bit multiplication and division instructions won't really
allow system_time() to be anywhere near as fast as on x86. :-/

09bb4e9ac5 The real_time_data structure contains an architecture specific
substructure now (that's the only member actually). The system time
offset is therefore accessed via architecture specific accessor
functions.
Note, that this commit breaks the PPC build. Since I want to rename at
least one file I've already changed, I can't avoid that.

7afa713acb Reorganized the boot platform dependencies in the kernel a bit.
Basically the architecture specific code is now responsible to
init and make use of the platform specific code, now. The reason
being that we have only one kernel per platform and thus cannot
decide at compile time, which platform to use (if any).
The PPC implementation features an abstract base class PPCPlatform
(implemented for all supported platforms) through which platform
support is provided.

* Implemented PPC specific system info stuff. Added a few PPC CPU
  types to <OS.h>.

  kernel address space (same issue as with the page table).

a1bcf2c880 * The OF memory management callback is now set in arch_mmu_init().
According to the spec we need to set it before taking over the MMU,
  but we can't call it before arch_mmu_init(), since we need the OF
  to allocate the page table. So we do it after we have allocated
  the new page table.
* Added PPC specific kernel_args: The virtual address ranges we want
  to keep in the kernel. We fill that in with the translations we
  find when initializing the MMU stuff. We remove the memory the
  boot loader occupies from those. Besides the stack for the boot
  loader only the OF stuff remains.
* arch_mmu_allocate() now starts to search at KERNEL_BASE for a free
  virtual address when no particular address is requested. This saves
  us further trouble in the kernel, since those allocations would
  need to be remapped otherwise.

10a83ac31f * Added tlbia() and tlbie() macros. Replaced ptesync() by ppc_sync();
the fact that I couldn't find ptesync in an otherwise more complete
  documentation I downloaded yesterday made me suspicious.
* arch_cpu_global_TLB_invalidate() uses tlbia now. The instruction is
  optional, but so is tlbie (how I understood it is that both exist,
  when the architecture implementation has a TLB). And the former loop
  looked just scary.
* Implemented arch_cpu_user_TLB_invalidate(). It does just the same as
  arch_cpu_global_TLB_invalidate().
* Some changes with respect to synchronization required on page table
  and segment register updates.
* Some more minor renaming. Pulled a new function
  remove_page_table_entry() out of unmap_tmap().
* In arch_vm_translation_map_init_post_area() we do now remap the page
  table into the kernel address space, if it was without before. The
  page table might actually be a good application for BAT, though.

51a3c450be The short story: we now have MTRR support on Intel and AMD CPUs (the latter
has not yet been tested, though - I'll do this after this commit):
* Removed the arch_memory_type stuff from vm_area; since there are only 8 memory
  ranges on x86, it's simply overkill. The MTRR code now remembers the area ID
  and finds the MTRR that way (it could also iterate over the existing MTRRs).
* Introduced some post_modules() init functions.
* If the other x86 CPUs out there don't differ a lot, MTRR functionality might
  be put back into the kernel.
* x86_write_msr() was broken, it wrote the 64 bit number with the 32 bit words
  switched - it took me some time (and lots of #GPs) to figure that one out.
* Removed the macro read_ebp() and introduced a function x86_read_ebp()
  (it's not really a time critical call).
* Followed the Intel docs on how to change MTRRs (symmetrically on all CPUs
  with caches turned off).
* Asking for memory types will automatically change the requested length to
  a power of two - note that BeOS seems to behave in the same, although that's
  not really very clean.

8fcd6b8e61 * renamed smp_boot.c to smp.cpp
* there is now a "Disable Hyper-Threading" safemode in the boot loader
* the SMP & HT menu items are now added in smp.cpp - and are only added
  if the system supports one of them.
* more cleanup to smp_apic.h
* removed cpuid() from the boot loader's support.S - instead, it will now
  use the one from the kernel.
* added a very weak HT detection: if the MP config only listed one CPU,
  and this CPU supports HT, we enable the other logic processor manually -
  as this currently doesn't work, it's disabled, though.

your system, I've also added a "Disable SMP" safemode option. The NO_SMP
define is still there, and will be removed once SMP works flawlessly.
Prints out infos about the interrupt entries in the MP config.

d08379a80b * Now we deal with all x86 exceptions, i.e. we no longer panic() when a
user application performs a division by zero or causes a general
  protection fault. For some exceptions (e.g. machine check) I wasn't
  quite sure whether they can be caused by user apps at all, so we panic()
  in those cases. Wouldn't harm, if someone more knowledgable would check
  this, though.
* Removed the unused fault handling stuff, respectively moved the little
  that was used into x86/arch_int.c.

f33c8020e2 Removed debug/console.c, we no longer need it. frame_buffer_console_init() is now
called by debug_init_post_vm().
Since the availability of a blue screen specific getchar() is static anyway, there
is no need for the sBlueScreenGetChar variable (only the message "only serial input
available" gets lost, but since that is platform specific anyway...).
Hello blue screen! We now have an on-screen KDL, to be enabled by the kernel
setting "bluescreen", just like on BeOS.
The blue screen does not yet support any cursor actions or backspace, though (need
to grab some stuff from our console driver).

9a63135f7c Cleanup of the debug stuff, prepared for blue screen debugging.
kernel_debugger() didn't do enough before; panic() did all the work - but
since the former is a public function as well, I moved all the functionality
to it. Also fixed a possible buffer overrun in panic().
Renamed dbg_* to debug_*.
"serial_debug_port" setting did not ignore negative values.

b20667b35b {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()

8e26b085e5 Fixed double fault handler. Personally I disclaim all responsiblity
for these changes. I was mostly just staring in amazement at the screen
while Axel and Thomas were discussing IA32 internals. A particularly
fascinating moment was when Thomas produced the cause of a bug we had
been trying to track down for hours off the top of his head (of course
iret behaves specially when the NT bit is set :-). His slowness must be
excused though, since he hadn't slept for more then 30 hours. ;-)

The code doesn't wholeheartedly deal with multi-processor machines yet.
Axel will certainly do some cleanup...

e5b0e0b5e3 Changed the set_segment_descriptor()'s usage of the limit/granularity
flag. Now, it will choose how to set the granularity by evaluating the
limit.
This call was actually already used this way in the kernel, so that
the TLS and TSS segments were much too large (harmless but incorrect).

9d06770cdc The iframe stack is now in a special structure iframe_stack.
Introduced a gBootFrameStack that is used until the first thread structure
is available - this allows stack crawls and useful register dumps during
early startup. Could also be solved differently by making sure there is
always a thread structure installed in %dr3 (ie. the boot thread would
get a static thread structure instead of a static iframe stack only).
This might be a better solution as i386_handle_trap() would no longer
need to check for an existing thread structure.

edb5566393 Fixed struct tss; there is no ss3/sp3.
Moved ptentry/pdentry to arch_vm_translation_map.c and renamed them to
page_table_entry and page_directory_entry.
Fixed a race condition that happened when memory was remapped (which
can currently happen because lock_memory() does not work correctly, and
there might be other conditions as well, like certain vm_store fault
handlers). Now, page table and directory entries are updated atomically.

85001a7cc6 * Fixed checking for DR6 bits after a debug exception (we were and'ing
with the bit number, not the respective mask).
* Added a small hack to allow single stepping to work in qemu.
  Apparently the BS bit in DR6 is not set when the debug exception
  is handled. So we always assume that a single step event occurred,
  when we couldn't recognize any other event, if the hack is enabled.

67a53f72af - the arch_vm_translation_map.c exported functions now have the arch_ prefix
- the above file now also exports a function to finally complete the kernel's
  address space translation map after semaphores became available (was just
  not done before)
- renamed some functions, especially the *_init2() functions are now called
  like *_init_post_area() to indicate they are called after the area functionality
  became available
- removed the _struct suffix from certain structures
- fixed some return types
- added prototype for vm_free_unused_boot_loader_range() to be called by
  arch code.

Changed the parameters for arch_thread_enter_uspace() - it now gets a pointer
to the thread structure and takes the user stack pointer from there (which
