* With post syscall debugging enabled, the x86 syscall handling didn't
remove all parameters from the stack after calling the respective user
debugger hook. Should have been harmless though, since the following
code didn't rely on the stack being in order.
* Added syscall pre/post (kernel) tracing functions
trace_{pre,post}_syscall(). They are generic, but need to be invoked
by the architecture specific syscall code. Currently only done for
x86.

* Added TODO that uninitialized entries must not be discarded.

invoke_debugger_command() is now automatically preceded by
"usage: <command name>", so the string passed to
add_debugger_command_etc() shouldn't contain it anymore.

add_debugger_command(), but additionally takes parameters "usage"
and "flags".
* Added add_debugger_command_alias() which creates another name for an
existing command.
* Added print_debugger_command_usage() to print a command's usage.
* invoke_debugger_command() intercepts invocations with "--help" and
prints the command's usage text, if it is known. If unknown, the
command will be called normally.
* Made use of the new functions in debug.cpp.

a command is executed anymore. Instead the least recently used
temporary variable is overwritten, if there's no free slot for a new
temporary variable.
* Removed the special handling for the command result variable ("_"). It
just works like any other temporary variable, now.
* Individual temporary variables can be removed (e.g. using the "unset"
command).
* Added unset_all_debug_variables() and "unset_all" command to unset
all persistent and temporary variables.
* Removed remove_all_temporary_debug_variables and renamed
remove_debug_variable() to unset_debug_variable().

Another target size (1, 2, 4, or 8 bytes) can be specified in braces
after the "*" (e.g. "*{2}address" for uint16).

* The kernel debugger does now define some temporary variables when
entered (current thread and team, etc.).

that is a little more powerful than BeOS'. It features:
- Persistent and temporary uint64 variables. The former kind is set
only by the user. The latter (those prefixed "_") can be set
automatically by commands, thus e.g. making it easier to access
members of a dumped structure. They are unset when the next command
is invoked. The special temporary variable "_" is defined as a
command's return value.
- Expressions can contain nested command invocations using brackets
("[ ... ]").
- Command lines are parsed by the expression parser, too. They can
contain command invocations (in brackets) and expressions (in
parentheses).
* Added debugger commands:
- expr: Evaluates the given expression and prints the result.
- unset: Undefines a variable.
- vars: Prints the values of all defined variables.
* Moved debugger command code into its own source file.

problem.

* Don't execute a command anymore, if the given prefix is ambiguous.
* Added tab completion for commands.
* Added on-the-fly help while typing a command line. It is triggered
by pressing tab at a position after the space following the command.
It is implemented by calling the command with argument "--help", which
doesn't work yet with most commands, but some already print their
usage in this case.

* Removed other incorrect key codes, except the one for BREAK, since it
is used (but won't work).
* Ctrl-Alt-Del now also resets the machine when in KDL, at least when
waiting for user input.
* arch_debug_blue_screen_getchar() does also generate the respective
escape sequences for HOME, END, and DELETE, now. Furthermore it
generates characters for Ctrl-A through Ctrl-Z.

Haiku it is rather slow (on my machine about 80% slower than on Zeta)
and sometimes a compilation even fails, due to what looks to me like a
problem with gcc's subprocess synchronization (our wait()/waitpid() or
friends might have some race condition).

23139 into trunk, with roughly the following changes (for details svn
log the branch):
* The int 99 syscall handler is now fully in assembly.
* Added a sysenter/sysexit handler and use it on Pentiums that support
it (via commpage).
* Got rid of i386_handle_trap(). A bit of functionality was moved into
the assembly handler which now uses a jump table to call C functions
handling the respective interrupt.
* Some optimizations to get user debugger support code out of the
interrupt handling path.
* Introduced a thread::flags fields which allows to skip handling of
rare events (signals, user debug enabling/disabling) on the
common interrupt handling path.
* Got rid of the explicit iframe stack. The iframes can still be
retrieved by iterating through the stack frames.
* Made the commpage an architecture independent feature. It's used for
the real time data stuff (instead of creating a separate area).
* The x86 CPU modules can now provide processor optimized versions for
common functions (currently memcpy() only). They are used in the
kernel and are provided to the userland via commpage entries.
* Introduced build system feature allowing easy use of C structure
member offsets in assembly code.
Changes after merging:
* Fixed merge conflict in src/system/kernel/arch/x86/arch_debug.cpp
(caused by refactoring and introduction of "call" debugger command).

into a buffer. The size of the S/G list for that buffer is now
temporarily set to the block size for the read request. This works
around the problem that the IDE bus manager would erroneously request
DMA for the complete buffer (32 KB), but issue a read request only for
one block, thus, after a few timeouts and bus resets, needing to resort
to PIO mode. Fixes bugs #985 and #1176.

ide_adapter_probe_controller(). ide_adapter_detect_controller() does
that itself, but ide_adapter_detect_channel() doesn't. Fixes off-by-one
bus master status register access. Shouldn't have caused any serious
problems, though.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22950 a95241bf-73f2-0310-859d-f6bbb57e9c96

5, 6, and 7).
* Modified output to include the name of the test.

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@22910 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Unmount when uninitializing a partition.
* Finished the media checker implementation, i.e. we rescan when a media
was inserted and uninitialize when ejected.
* Turned the disk device media checker from a kernel daemon into a thread.

* The POSIX test suite is copied to the image when the jam variable
HAIKU_ADD_POSIX_TEST_SUITE_TO_IMAGE is defined (cf. UserBuildConfig.sample).
* Added difftime and fork tests to the test suite run script.

"page_allocations" command.
* Fixed a problem in the page scrubber. It temporarily removed pages
from the free list, which could have been reserved by someone else.
When actually allocating the reserved pages, that someone could find
free and clear lists empty and would therefore rightfully panic
("Had reserved page, but there is none!").

K{Disk,File,Partitioning}System writing methods. It is now required
that the caller has marked the concerned partitions busy, hence we can
(read-)access them without needing a lock. The module interfaces will
will be changed to take advantage of the fact as well. The methods take a
disk_job_id instead of a KDiskDeviceJob* now, though I haven't quite
decided, whether we need it at all or just want to add a special
handling in the cases where notifications during the operation make
sense.
* Reimplemented the disk device write support syscalls (save
_user_move_partition() for which other module hooks are needed). They
call the KDiskSystem methods, now.

* Removed the disk device job support from the disk device manager.
* K{Disk,File,Partitioning}System:

* Adjusted the prototypes of the disk device modification syscalls.
Commented out their implementations for the time -- they'll mostly
have to be rewritten completely.
* Implemented the userland disk device jobs.

a while ago that removed the incorrect automatic addition of Haiku header
directories in case of targets other than "haiku". The app server test
environment does now almost build again. The problem left is related to the
recent changes of the accelerant interface. I suppose someone in the knows
should decide if we can simply use our header or if special handling is
needed.

DiskDeviceJobQueue.
* Basic synchronous implementation of BDiskDevice::CommitModifications(),
ignoring the given parameters, though.
* Some more work on DiskDeviceJobGenerator: Added class
PartitionReference which will reference a partition while the jobs are
executed. The generator manages the mapping of partitions to those
references now. Also exemplarily implemented the generation of the
InitializeJob.
* Moved support functionality to private header DiskDeviceUtils.h.
