Added basic support for booting from CD - it doesn't give CDs a higher priority,
so you could end up booting from HD when you didn't explicetly select "CD-ROM"
in the boot loader. Eventually, it should only boot from HD in this case, if
booting from CD failed (because of a missing boot partition or whatever).
fs_mount(), _kern_mount(), and _user_mount() will now return the dev_t of the
mounted device, and not just B_OK. Maybe we should have fs_unmount() work on
a dev_t instead of a path as well...

per file descriptor (a descriptor can be shared among several slots). There is now a
second table in the io_context structure that contains that information in a bitmap.
There are now two new (private) functions to control the close-on-exec flag, fd_close_on_exec(),
and fd_set_close_on_exec().
F_DUPFD, dup(), and dup2() are supposed to clear the close-on-exec flag on the duplicated
slot - this fixes bug #57 (no output after a redirect of a shell builtin).

return to the caller, since signals are handled before returning to user space).

and exec_team() have an additional "kernel" argument and will copy the arguments
themselves (or rather, delegate that to create_team_arg()).
When team_create_thread_start() is called, it will take over ownership and is
responsible for deleting it - this also fixed a memory leak in case the user
stack area couldn't be created.
Also changed comment after exit_thread(): since this call only delivers a signal, the
code after it will still get executed.
This fixes the crashing symptom of bug #50.

Some fields of fs_mount were not properly initialized when FS's mount function
was called, and therefore, could let get_mount() return a mount structure that

There, we need to detect the modified state from the mapping, too - the
vm_page state itself might not be up to date.

never written back.

even if "kernel_startup" was "true". Page faults are now no longer allowed
during kernel startup (and could be easily avoided). The only situation where
we accept page faults with interrupts turned off now is during a kernel debugger
session.
Added a command debug_debugger_running() to test for that situation.
kernel_debugger() no longer sets kernel_startup while it's running; there should
be no situation when this could be helpful.
Interrupts are no longer enabled when a page fault happens in the kernel
debugger.
This potentially fixes all sorts of problems, and not only in the kernel debugger,
it could also have affected SMP (will test later).

pages, ie. they considered the areas to be B_LAZY_LOCK. But that doesn't really make
sense and potentially cause page faults where you wouldn't expect them (and where
it's not a good idea to trigger them).
Reworked display_mem() (used by the dw/db/ds commands in the kernel debugger) to
be a bit more sane, improved formatting, and allows it to work on non-existing
memory without a panic.
The "area" debugger command now also accepts an address (contained by the area)
as argument - and it will now always print out an error message if no matching
area could be found.
Replaced all dprintf() calls to kprintf() calls for the kernel debugger functions.

Just like on BeOS, the overall maximum is 65536 semaphores for now - the mechanism
tends to make more semaphores available than the one under BeOS, though (which is
intended).

node: like in BeOS, it *must* own the root node (ie. via publish_vnode()),
unlike in BeOS, it must also drop that reference on unmount (symmetrical
behaviour definitely makes more sense to me than the Be way).
Since all existing file systems for Haiku behaved differently, I brought them
in line (only pipefs already adhered to that new standard for some reason,
rootfs did only released the node, devfs did nothing - despite it's probably
not really useful to be able to unmount them).
fs_mount() will now panic if a file system does not do this correctly (useful
for file system developing).
Unmounting is now theoretically working again: when trying to unmount a BFS
volume, the kernel crashes in the block cache destruction... (but that's work
for tomorrow).

only a read lock on the inode, or without a lock at all (in case of prefetching) - it
is now using the cache_ref's lock to make sure it's retrieved only once and doesn't
waste/corrupts any memory.
- since that fix made it mandatory to fix write_chunk_into_cache() to not call pages_io()
while holding the cache_ref's lock (was a to-do item before), I changed it to make
that possible.
- It now also supports write-through caches in theory - as there is no way yet to tell
a cache to work this way.
- Optimized for the not so uncommon case of writing the last part of a file that is not
a multiple of the page size - it won't call pages_io() anymore then, but zero the rest
of the page directly.
- vm_page_write_modified() is now calling write_page() without holding the cache_ref's
lock as well.
The updated write_chunk_to_cache() is not so well tested, though, but appears to work
so far.

Broken escape sequences are now properly ignored (read one character too much before).
Since the current line buffer is part of the history, we now delete that buffer when
crossing the current line again while traversing the history (restoring the former
buffer would be the nicest way, but that would require another empty buffer and more
copying).
Cleanup.

Therefore, cache_prefetch() no longer crashes when trying to prefetch

free_vnode() does now also remove the vnode from the hash - this is done

vm_copy_area() no longer always sets B_KERNEL_WRITE_AREA if no kernel protection

some areas to be read/write when read-only would have been enough.

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.

hardly atomic, so we need to grab the thread lock after all.

could have destroyed the BFS integrity... (just happened to me, that's how I
noticed it)

opened devices, and one for opened directories.
Also adds and removes those directory cookies correctly now.

removed when no longer used (the same bug is still present in devfs, btw,
and can potentially cause crashes).
Cleanup of the cookie code, it's now using util/list.h.
Now issues B_STAT_CHANGED notifications when directory entries changed.
rootfs_rename() was completely broken for "inter-directory" movements.

(mostly happens in the kernel debugger). Not tested, though.

success (they just kept the passed in buffer size unchanged).

- it's now much cleaner than before
- it now actually works in combination with realloc() (the fix from before didn't work)
- got rid of the WALL_ALIGNMENT definition
- can now handle different WALL_SIZEs

interrupt service register bit is never set, anyway...
Thanks to Korli for reporting.

forwarded to the standard interrupt handler. Untested, though.

Some cleanup.

VFS's interface, so that a file system only has to implement one interface.
As a side effect, the automatic file system detection may now work (not yet
tested, though).

will return true in the former case).
vm_delete_areas() is now using this information to print out a warning
in this case (so that a missing vm_put_area() can now be found easier).

following 1152 MB - that area only guarantees that the heap can grow this much before
the application need the memory for something else. And even then, the heap range
is reused from top-to-bottom, allowing for maximum heap usage. Of course, if the
memory after the heap range is not claimed yet, it can still be claimed by the heap,
too. Added new syscall to create the reserved range.
Fixed a bug in vm_delete_areas(): when it removed reserved areas, the area list
could get messed up.
Fixed a bug in resize_area(): resized areas could never be deleted (missing vm_put_area())!
resize_area() now supports reserved regions (but not perfectly yet, see ToDo items).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12692 a95241bf-73f2-0310-859d-f6bbb57e9c96
only if memory becomes tight, and then the range is used from end to
start.
This is useful to reserve heap address ranges.

along the protection flags).
Changed the handling of B_STACK_AREA types and anonymous vm_areas: now
every area can overcommit if B_OVERCOMMITTING_AREA was specified.
B_STACK_AREA areas are still automatically overcommitting, but
B_KERNEL_STACK_AREA areas no longer.
vm_store_anonymous_noswap.c now only tests for guard pages if there were
any specified which is only done for B_STACK_AREA areas.

(right now, it's still malloc/free, just encapsulated in an allocator class).

This reduces the stack usage quite a lot, and since file system calls could be
nested (for example, a mounted image on a volume), definitely a must, too.
Might be a good idea for user calls, too, though, although it's not urgent.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12636 a95241bf-73f2-0310-859d-f6bbb57e9c96
mounted, but no one told it about its volume ID - that caused "mountvolume"
not to be able to return a valid mount point.

file system has been mounted, it would have crashed (that for example
happened if you deleted the kernel settings file...).

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()

Decreased the pipe buffer to 32768 bytes (it's 4096 on BeOS).
pipefs_select/deselect() did no locking.
Switched to using the BenaphoreLocker where possible.
