| | | | | | | | | | | | | | | | | | | | different stub mechanism 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.

* ACPICA: Debugger: Convert some mechanisms to OSPM specificLv Zheng2015-12-155-146/+38Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

* ACPI: Enable build of AML interpreter debuggerLv Zheng2015-10-2212-29/+21Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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() Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

* ACPICA: Debugger: Add thread ID support so that single step mode can only ↵Lv Zheng2015-10-224-2/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | apply to the debugger thread 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. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

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).

* ACPICA: Debugger: Split debugger initialization/termination APIsLv Zheng2015-08-253-22/+0Star
| | | | | | | | | | | | | | | | | | | | ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432 It is likely that the debugger is enabled only when a userspace program explicitly tells a kernel to do so, so it shouldn't be initialized as early as current implementation. The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to call the new APIs by itself. And BSD developers may also get notified to invoke the APIs for DDB enabling. Lv Zheng. This patch doesn't affect Linux kernel as debugger is currently not enabled in the Linux kernel.

* ACPICA: Tables: Fix global table list issues by removing fixed table indexesLv Zheng2015-08-257-58/+51Star
| | | | | | | | | | | | | | | | | | | | | | | | | ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941 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.
