disk system, if the partition already has a disk system set. This can happen
when the disk system's initialization function is lazy and just lets the DDM
rescan the partition. In bad cases the previous disk system has a higher
priority than the new one and, if its on-disk structures have not been
destroyed, it will win the rescan. Not setting the disk system in such cases at
least leaves the partition object in a consistent state.

* Don't fall back to the disk device, if no partition was selected. No idea why
that was done. It led to operations (like initialize) being enabled that
would fail, if invoked.
* Don't check CanInitialize() on the selected partition with its current disk
system to determine whether to enable the initialization menu. No idea why
that was done either. It led to the menu being disabled, when there was no
reason for it.
* Also disable the initialization menu when no partition is selected.

loader menu. It displays what the boot loader has logged so far. Might be
interesting for early boot issues when serial debugging is not possible.

* If we detect ACPI 2.0 or higher, the spec says we should use the XSDT rather
than the RSDT. Attempt to do so, falling back to the RSDT if the former fails
to be mapped/validated.
* Refactored acpi_find_table into a templated version to account for the fact
that the XSDT exports different pointer widths for its links to other tables
than the RSDT.

* Since the updated Time prefs didn't make it into alpha3, I kept the older
catkeys in SVN.
* Renamed "Application name" to "System name" manually in the catkeys of
CodyCam and Poorman. For some reason HTA didn't get these changes in the
code...

which don't wait for a character, but return -1 when no character is
available ATM. Implemented correctly for x86 only.
* Changed the semantics of the debugger_module_info::debugger_getchar() hook.
It is supposed to return immediately now.
* Adjusted usb_keyboard accordingly. Hacked UHCI's debug_process_transfer() to
achieve that. It does now start, check, or cancel a transfer. Split
UHCI::ProcessDebugTransfer() into StartDebugTransfer(), and
CheckDebugTransfer() accordingly, and also added a CancelDebugTransfer().
The latter seems to have issues. Michael, please have a look. I have no clue
what I'm doing. :-)
* Adjusted kgetc() to poll all possible inputs using the new
functions/semantics. This allows to use any input (USB, PS/2, serial) in KDL.
* Removed the no longer needed "serial_input" command.
* read_line(): Also support 0x7f as backspace code. That's what xterm sends.

actually misleading, since it specifies the length of the xsdt rather than the rsdt. Furthermore, it is only available if the BIOS reports ACPI version 2.0 or greater. Since we don't currently support the XSDT, we can't rely on that field and have to resort to the previous approach of mapping the RSDT header in order to determine the length of the RSDT itself.
Also add validation of the RSDT's checksum so we don't get tripped up by BIOS's with broken tables.
Should fix boot problems that were introduced by r42105.

* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
handlers have been moved to teams. Fixes#5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
of the real-time signal range. Closes#1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes#6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
[set]itimer(). Closes#5682.
* Implemented support for thread cancellation. Closes#5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes#7554.
* Lots over smaller more or less related changes.

The server name is checked while typing and if it is not valid the text is made
red. Invalid entries cannot be added to the list.
Also made the server add message be the invoking message so that the enter key
works to add a server.
After adding a valid server the text is cleared.
Valid servers names are alpha-numeric with periods, dashes and underscores.
Could need some things added but that should cover 99% of the cases.

exceptions (page faults and the like). The handler dumps possibly interesting
information (registers, a (numerical) stack trace) to the serial output, and,
if possible, also to the screen. That should help debugging boot loader
crashes.
* For the IDT the boot loader sets up for the kernel the descriptors are set up
the same way, so until the kernel initializes the IDT itself (arch_init()) the
facility is still in place and can thus catch very early kernel boot crashes.
Unfortunately the on-screen output doesn't seem to work anymore at that point,
so the output only goes to the serial port...
* ... and to the debug syslog -- dprintf() does now append it there after
debug_cleanup() has been called. Seems to work fine in qemu, but when I tested
it on real hardware the debug syslog was gone.

- Introduce TeamMemoryBlockOwner to act as an interface for blocks to
remove themselves from the manager when they expire. Consequently remove
TeamMemoryBlock's direct reference to the block manager.
- Simplify GetBlock() to remove unnecessary recursion.
- Store dead blocks in a doubly linked list instead of another hash table.
- Minor style fixes.

only halfway finished. The way it is supposed to work is that there are two
tty cookies, representing the system and the device side. Reads and writes
coming from the system and going to the device are using the system cookie
while reads and writes coming from the device use the device cookie.
* Move writing to the device into an output thread, similar to how reading from
the device works. This isn't necessarily a good idea and might be moved back
into the write hook again to ensure that writes can be made blocking. Right
now if you just write and then close, the writes will most likely be canceled
before every going out to the device.
* Removed the read and write lock mutex. They aren't necessary as the tty layer
will serialize the reads and writes anyway.
* Made simply copying the data to the write buffer the default implementation of
the OnWrite callback and removed the OnWrite in ACMDevice. The ProlificDevice
didn't provide an OnWrite hook before, so it would've never written anything.
* Break out the baud index to speed mapping into an inline function. Since the
defines might change in termios.h just adding an array is a bit fragile (it
already missed one entry and would've been broken for certain speeds).
This should make usb_serial usable for some (most?) cases. I've tested this with
an Arduino board that uses an FTDI interface. As mentioned above, since writes
currently just write into the tty layer and don't wait for the data to be
flushed, and since close doesn't wait for the output buffers to be drained
either, a simple write and close (as in "echo a > /dev/ports/usb0") will in most
cases cancel the output before it is written to the device. I'm looking into
a few ways to fix that next.

target team's memory. Used by InspectRequested() to perform the actual work.
* TeamDebugger: Added InspectRequested() hooks to allow clients to ask for

As yet these are more or less stubs and not yet hooked in.
