ACPICA commit 11522d6b894054fc4d62dd4f9863ec151296b386
The ACPI_DEBUGGER_EXEC is a problem now when the debugger code is compiled
but runtime disabled. They actually will get executed in this situation.
Although such executions are harmless if we can correctly make
acpi_db_single_step() a runtime stub, users may still do not want to see the
debugger print messages logged into OSPMs' kernel logs when a debugger
driver is not loaded to enable the debugger during runtime.
This patch fixes this issue by introducing new stub mechanism instead of
ACPI_DEBUGGER_EXEC. Lv Zheng.

The following mechanisms are OSPM specific:
1. Redirect output destination to console: no file redirection will be
needed by an in-kernel debugger, there is even no file can be accessed
when the debugger is running in the kernel mode.
2. Output command prompts: programs other than acpiexec can have different
prompt characters and the prompt characters may be implemented as a
special character sequence to form a char device IO protocol.
3. Command ready/complete handshake: OSPM debugger may wait more conditions
to implement OSPM specific semantics (for example, FIFO full/empty
conditions for O_NONBLOCK or IO open/close conditions).
Leaving such OSPM specific stuffs in the ACPICA debugger core blocks
Linux debugger IO driver implementation.
Several new OSL APIs are provided by this patch:
1. acpi_os_initialize_command_signals: initialize command handshake mechanism
or any other OSPM specific stuffs.
2. acpi_os_terminate_command_signals: reversal of
acpi_os_initialize_command_signals.
3. acpi_os_wait_command_ready: putting debugger task into wait state when a
command is not ready. OSPMs can terminate command loop by returning
AE_CTRL_TERMINATE from this API. Normally, wait_event() or
wait_for_multiple_object() may be used to implement this API.
4. acpi_os_notify_command_complete: putting user task into running state when a
command has been completed. OSPMs can terminate command loop by
returning AE_CTRL_TERMINATE from this API. Normally, wake_up() or
set_event() may be used to implement this API.
This patch also converts current command signaling implementation into a
generic debugger layer (osgendbg.c) to be used by the existing OSPMs or
acpiexec, in return, Linux can have chance to implement its own command
handshake mechanism. This patch also implements acpiexec batch mode in a
multi-threading mode comaptible style as a demo (this can be confirmed by
configuring acpiexec into DEBUGGER_MULTI_THREADED mode where the batch mode
is still working). Lv Zheng.
Note that the OSPM specific command handshake mechanism is required by
Linux kernel because:
1. Linux kernel trends to use wait queue to synchronize two threads, using
mutexes to achieve that will cause false "dead lock" warnings.
2. The command handshake mechanism implemented by ACPICA is implemented in
this way because of a design issue in debugger IO streaming. Debugger IO
outputs are simply cached using a giant buffer, this should be tuned by
Linux in the future.

This patch enables ACPICA debugger files using a configurable
CONFIG_ACPI_DEBUGGER configuration item. Those debugger related code that
was originally masked as ACPI_FUTURE_USAGE now gets unmasked.
Necessary OSL stubs are also added in this patch:
1. acpi_os_readable(): This should be arch specific in Linux, while this
patch doesn't introduce real implementation and a complex mechanism to
allow architecture specific acpi_os_readable() to be implemented to
validate the address. It may be done by future commits.
2. acpi_os_get_line(): This is used to obtain debugger command input. This
patch only introduces a simple KDB concept example in it and the
example should be co-working with the code implemented in
acpi_os_printf(). Since this KDB example won't be compiled unless
ENABLE_DEBUGGER is defined and it seems Linux has already stopped to
use ENABLE_DEBUGGER, thus do not expect it can work properly.
This patch also cleans up all other ACPI_FUTURE_USAGE surroundings
accordingly.
1. Since linkage error can be automatically detected, declaration in the
headers needn't be surrounded by ACPI_FUTURE_USAGE.
So only the following separate exported fuction bodies are masked by
this macro (other exported fucntions may have already been masked at
entire module level via drivers/acpi/acpica/Makefile):
acpi_install_exception_handler()
acpi_subsystem_status()
acpi_get_system_info()
acpi_get_statistics()
acpi_install_initialization_handler()
2. Since strip can automatically zap the no-user functions, functions that
are not marked with ACPI_EXPORT_SYMBOL() needn't get surrounded by
ACPI_FUTURE_USAGE.
So the following function which is not used by Linux kernel now won't
get surrounded by this macro:
acpi_ps_get_name()

When the debugger is running in the kernel mode, acpi_db_single_step() may
also be invoked by the kernel runtime code path but the single stepping
command prompt may be erronously logged as the kernel logs and runtime code
path cannot proceed.
This patch fixes this issue by adding acpi_gbl_db_thread_id for the debugger
thread and preventing acpi_db_single_step() to be invoked from other threads.
It is not suitable to add acpi_thread_id parameter for acpi_os_execute() as
the function may be implemented as work queue on some hosts. So it is
better to let the hosts invoke acpi_set_debugger_thread_id(). Currently
acpiexec is not configured as DEBUGGER_MULTI_THREADED, but we can do this.
When we do this, it is better to invoke acpi_set_debugger_thread_id() in
acpi_os_execute() when the execution type is OSL_DEBUGGER_MAIN_THREAD. The
support should look like:
create_thread(&tid);
if (type == OSL_DEBUGGER_MAIN_THREAD)
acpi_set_debugger_thread_id(tid);
resume_thread(tid);
Similarly, semop() may be used for pthread implementation. But this patch
simply skips debugger thread ID check for application instead of
introducing such complications as there is no need to skip
acpi_db_single_step() for an application debugger - acpiexec.
Note that the debugger thread ID can also be used by acpi_os_printf() to
filter out debugger output. Lv Zheng.

The quit/exit commands shouldn't invoke acpi_terminate_debugger() and
acpi_terminate() right in the user command loop, because when the debugger
exits, the kernel ACPI subsystem shouldn't be terminated (acpi_terminate())

(acpi_terminate_debugger()) rather than being terminated itself. Leaving such
invocations causes kernel panic when the debugger is shipped in the Linux
kernel.

Some logics actually relying on the existence of FADT, currently relies on
the number of loaded tables. This false dependency can easily trigger
regressions. One of them has been introduced by commit 8ec3f45907
(ACPICA: Tables: Fix global table list issues by removing fixed table).
The commit changing the fixed table indexes results in the change of FADT
table index, originally, it was 3 (thus the installed table count should be
greater than 4), while currently it is 0 (and the installed table count may
be 3).
This patch fixes this regression by cleaning up the code. Lv Zheng.

ACPICA commit 42d7ad7bfb1cfb95183c1386c77509f2036f521d
When acpi_gbl_db_opt_verbose is used in acpi_dm_descending_op() (invoked by
acpi_dm_disassemble()), it is actually exported by the disassembler but used
by the debugger to distinguish the output of the disassembler for different
debugger commands. It is by default TRUE but is set to FALSE for control
method disassembly command - "disassemble". So it's initialization should
be a part of the ACPI_DISASSEMBLER conditioned code. This patch uses
ACPI_INIT_GLOBAL to achieve a clean manner so that when ACPI_DISASSEMBLER
is not defined, ACPI_DEBUGGER conditioned code needn't link to this option.
Since it is a disassembler exported variable, it is renamed to
acpi_gbl_dm_opt_Verbose in this patch.
As VERBOSE_PRINT() macro has only one user, this patch also removes the
definition of this macro. Lv Zheng.

The fixed table indexes leave holes in the global table list:
1. One hole can be seen when there is only 1 FACS provided by the BIOS.
2. Tow holes can be seen when it is a reduced hardware platform.
The holes do not break OSPMs but have broken ACPI debugger "tables"
command.
Also the "fixed table indexes" mechanism may make the descriptors of the
standard tables installed earlier than DSDT to be overwritten by the
descriptors of the fixed tables. For example, FACP disappears from the
global table list after DSDT is installed.
This patch fixes all above issues by removing the "fixed table indexes"
mechanism which is too complicated to be maintained in a regression safe
manner. After removal, the table loader will determine the indexes of the
fixed tables. Lv Zheng.

ACPICA commit 2fefacf73825b0ec96bbfc4f70a256735b715d6c
This mode emits AML code along with the ASL code.
A new global was needed to ensure the listing mode is
completely separate from the debugger verbose mode.
Emits the correct AML offset for the AML code.
The -l option now works for both the compiler and disassembler.
Linux kernel is not affected by this commit.

ACPICA commit ed7769e832de6c7ba90615480d916c85fd100422
If a table load fails, delete all namespace objects created by the
table, otherwise these objects will be uninitialized, causing
problems later. This appears to be a very rare problem.
Also handle the unitialized node problem to prevent possible
faults. ACPICA BZ 1185.

ACPICA commit add72dca18ab5d02f1bf9b08027570e58da520e8
This mode will emit AML byte code after each ASL statement.
This is a prototype only and requires additional development.
This patch only affects ACPICA disassembler which is not in the kernel
source tree.

ACPICA commit 2164923d60429eea7cd5a4a8629b607af7325afa
Some disassembler APIs should rather be debugger APIs. This patch moves
them to the debugger folder to be ready for debugger porting.
Since there is no in-kernel ACPICA debugger in the kernel source tree, this
patch doesn't affect the Linux kernel.

ACPICA commit 7c490c28a18b435c543c6b410e7e7c2131fccc78
ACPICA implements all non-ANSI functions locally. However, there
are sometimes two or more versions of the same function throughout
the ACPICA code. This change fixes this.
