ACPICA 20050408 from Bob Moore Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>

ACPICA: Fix indentation issues for macro invocations. During the automatic translation of the upstream ACPICA source code into Linux kernel source code some extra white spaces are added by the "indent" program at the beginning of each line which is an invocation of a macro and there is no ";" at the end of the line. For this reason, a new mode has been added to the translation scripts to remove the extra spaces inserted before invoking such macros and add an empty line between the invocations of such macros (like the other function declarations). This new mode is executed after executing "indent" during the Linux release process. Consequently, some existing ACPICA source code in the Linux kernel tree needs to be adjusted to allow the new scripts to work correctly. The affected macros and files are: 1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h): This macro is used as a wrapper for hardware dependent APIs to offer a stub when the reduced hardware is configured during compilation. 2. ACPI_EXPORT_SYMBOL (utglobal.c): This macro is used by Linux to export symbols to be found by Linux modules. All such invocations are well formatted except those exported as global variables. This can help to reduce the source code differences between Linux and upstream ACPICA, and also help to automate the release process. No functional or binary generation changes should result from it.

ACPICA: Linuxize: Cleanup spaces after special macro invocations. This patch reflects the improvment of a cleanup step which is performed in the release process. There are still spaces in the "linuxized" ACPICA files after special macro invocations. This is because indent treats comments and pre-processor directives as spaces, thus we need to skip them. Before applying this patch, cleanup code will search from keyword back to end of line and wipe spaces between them. After applying this patch, cleanup code will search to the end of the macro invocations, skip "empty lines", "comments" and "pre-processor directives", then wipe the spaces between the new line and the first non-spaces characters.

ACPI / ACPICA: Fix reference counting problems with GPE handlers If a handler is installed for a GPE associated with an AML method and such that it cannot wake up the system from sleep states, the GPE remains enabled after the handler has been installed, although it should be disabled in that case to avoid spurious execution of the handler. Fix this issue by making acpi_install_gpe_handler() disable GPEs that were previously associated with AML methods and cannot wake up the system from sleep states. Analogously, make acpi_remove_gpe_handler() enable the GPEs that are associated with AML methods after their handlers have been removed and cannot wake up the system from sleep states. In addition to that, fix a code ordering issue in acpi_remove_gpe_handler() that renders the locking ineffective (ACPI_MTX_EVENTS is released temporarily in the middle of the routine to wait for the completion of events already in progress). For this purpose introduce acpi_raw_disable_gpe() and acpi_raw_enable_gpe() to be called with acpi_gbl_gpe_lock held and rework acpi_disable_gpe() and acpi_enable_gpe(), respectively, to use them.

ACPICA: Clear status of GPEs on first direct enable ACPI GPEs (other than the EC one) can be enabled in two situations. First, the GPEs with existing _Lxx and _Exx methods are enabled implicitly by ACPICA during system initialization. Second, the GPEs without these methods (like GPEs listed by _PRW objects for wakeup devices) need to be enabled directly by the code that is going to use them (e.g. ACPI power management or device drivers). In the former case, if the status of a given GPE is set to start with, its handler method (either _Lxx or _Exx) needs to be invoked to take care of the events (possibly) signaled before the GPE was enabled. In the latter case, however, the first caller of acpi_enable_gpe() for a given GPE should not be expected to care about any events that might be signaled through it earlier. In that case, it is better to clear the status of the GPE before enabling it, to prevent stale events from triggering unwanted actions (like spurious system resume, for example). For this reason, modify acpi_ev_add_gpe_reference() to take an additional boolean argument indicating whether or not the GPE status needs to be cleared when its reference counter changes from zero to one and make acpi_enable_gpe() pass TRUE to it through that new argument.

ACPICA: Events: Add parallel GPE handling support to fix potential redundant _Exx evaluations There is a risk that a GPE method/handler may be invoked twice.

APIC) are run in serial. Note that, this is a known potential gap and we had an approach, locking entire non-raw-handler processes in the top-half IRQ handler and handling all raw-handlers out of the locked loop to be friendly to those IRQ chip/driver. But the approach is too complicated while the issue is not so real, thus ACPICA treated such issue (if any) as a parallelism/quality issue of the underlying IRQ chip/driver to stop putting it on the radar. Bug in link #1 is suspiciously reflecting the same cause, and if so, it can also be fixed by this simpler approach. But it will be no excuse an ACPICA problem now if ACPICA starts to poll IRQs itself. In the changed scenario, _Exx will be evaluated from the task context due to new ACPICA provided "polling after enabling GPEs" mechanism. And the above figure uses edge-triggered GPEs demonstrating the possibility of evaluating _Exx twice for one status bit flagging. As a conclusion, there is now an increased chance of evaluating _Lxx/_Exx more than once for one status bit flagging. However this is still not a real problem if the _Lxx/_Exx checks the underlying hardware IRQ reasoning and finally just changes the 2nd and the follow-up evaluations into no-ops. Note that _Lxx should always be written in this way as a level-trigger GPE could have it's status wrongly duplicated by the underlying IRQ delivery mechanisms. But _Exx may have very low quality BIOS by BIOS to trigger real issues. For example, trigger duplicated button notifications. To solve this issue, we need to stop reading a bunch of enable/status register bits, but read only one GPE's enable/status bit. And GPE status register's W1C nature ensures that acknowledging one GPE won't affect another GPEs' status bits. Thus the hardware GPE architecture has already provided us with the mechanism of implementing such parallelism. So we can lock around one GPE handling process to achieve the parallelism: 1. If we can incorporate GPE enable bit check in detection and ensure the atomicity of the following process (top-half IRQ handler): READ (enable/status bit) if (enabled && raised) CLEAR (enable bit) and handle the GPE after this process, we can ensure that we will only invoke GPE handler once for one status bit flagging. 2. In addtion for edge-triggered GPEs, if we can ensure the atomicity of the following process (top-half IRQ handler): READ (enable/status bit) if (enabled && raised) CLEAR (enable bit) CLEAR (status bit) and handle the GPE after this process, we can ensure that we will only invoke GPE handler once for one status bit flagging. By doing a cleanup in this way, we can remove duplicate GPE handling code and ensure that all logics are collected in 1 function. And the function will be safe for both IRQ interrupt and IRQ polling, and will be safe for us to release and re-acquire acpi_gbl_gpe_lock at any time rather than raw handler only during the top-half IRQ handler.

Following improvements are thus achieved in the release automation by this commit which are originally maintained manually: - acpi_status acpi_ev_remove_global_lock_handler(void); +acpi_status acpi_ev_remove_global_lock_handler(void); - acpi_status +acpi_status acpi_ev_match_gpe_method(acpi_handle obj_handle, - acpi_status acpi_subsystem_status(void); +acpi_status acpi_subsystem_status(void); - acpi_status acpi_install_notify_handler(acpi_handle device, u32 handler_type, +acpi_status acpi_install_notify_handler(acpi_handle device, u32 handler_type, - acpi_status +acpi_status acpi_acquire_mutex(acpi_handle handle, acpi_string pathname, u16 timeout); - acpi_status +acpi_status acpi_get_sleep_type_data(u8 sleep_state, u8 *slp_typ_a, u8 *slp_typ_b); - acpi_status acpi_leave_sleep_state_prep(u8 sleep_state); +acpi_status acpi_leave_sleep_state_prep(u8 sleep_state); Some empty lines are restored by this commit due to the change of the removal implementation.

ACPICA 20050408 from Bob Moore Fixed three cases in the interpreter where an "index" argument to an ASL function was still (internally) 32 bits instead of the required 64 bits. This was the Index argument to the Index, Mid, and Match operators. The "strupr" function is now permanently local (acpi_ut_strupr), since this is not a POSIX-defined function and not present in most kernel-level C libraries. References to the C library strupr function have been removed from the headers. Completed the deployment of static functions/prototypes. All prototypes with the static attribute have been moved from the headers to the owning C file. ACPICA 20050329 from Bob Moore An error is now generated if an attempt is made to create a Buffer Field of length zero (A CreateField with a length operand of zero.) The interpreter now issues a warning whenever executable code at the module level is detected during ACPI table load. This will give some idea of the prevalence of this type of code. Implemented support for references to named objects (other than control methods) within package objects. Enhanced package object output for the debug object. Package objects are now completely dumped, showing all elements. Enhanced miscellaneous object output for the debug object. Any object can now be written to the debug object (for example, a device object can be written, and the type of the object will be displayed.) The "static" qualifier has been added to all local functions across the core subsystem. The number of "long" lines (> 80 chars) within the source has been significantly reduced, by about 1/3. Cleaned up all header files to ensure that all CA/iASL functions are prototyped (even static functions) and the formatting is consistent. Two new header files have been added, acopcode.h and acnames.h. Removed several obsolete functions that were no longer used. Signed-off-by: Len Brown <len.brown@intel.com>
