no items can be removed from that list - nevertheless, it's wrong.

can now only happen if the thread is killed.
_user_receive_data() will now longer pass B_CAN_INTERRUPT to receive_data(),
but B_KILL_CAN_INTERRUPT - this should fix the problem Stefano experienced
with this function, even if I couldn't reproduce it.

Added tracking for the last transaction in the block cache; that way it can test
if the last transaction has been closed before opening a new one.

block_range::Free() did not update the chunk's used_mask correctly.

This helps to reduce the flood of commands for those blue screen "users" :-)
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13018 a95241bf-73f2-0310-859d-f6bbb57e9c96
will do that anytime soon, and it should be done by using node monitoring,
anyway.
devfs_open_dir() now makes sure the directory contents are up-to-date - this
should fix the app_server device lookup.
Disabled debug output in the read/write hooks to improve its usage.
Renamed part_map to partition.
Minor cleanup.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12935 a95241bf-73f2-0310-859d-f6bbb57e9c96
Added new devfs_add_driver() function that the device manager will now call
to register new drivers.
Devfs will now keep a list of known drivers and remembers, if they have
been initialized already - a driver can now safely scan the directory it's
in while being scanned itself without having its hooks called twice.
Devfs is now using a recursive lock instead of a mutex (that's not really
a requirement right now, but would allow us to keep the fs lock during
scanning).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12933 a95241bf-73f2-0310-859d-f6bbb57e9c96
currently needs even more memory than the old one 8-)
Not cleaned up at all.

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).

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.

noticed it)

opened devices, and one for opened directories.
Also adds and removes those directory cookies correctly now.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12855 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12821 a95241bf-73f2-0310-859d-f6bbb57e9c96
- 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.
For more information on the subject: http://www.ggd.nsu.ru/~serg/bsdfaq/part3.html#316
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12786 a95241bf-73f2-0310-859d-f6bbb57e9c96
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12693 a95241bf-73f2-0310-859d-f6bbb57e9c96
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).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12662 a95241bf-73f2-0310-859d-f6bbb57e9c96
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...).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12547 a95241bf-73f2-0310-859d-f6bbb57e9c96
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()
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@12477 a95241bf-73f2-0310-859d-f6bbb57e9c96
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.
