The recent changes in module-level code mean that the table load becomes a method execution. If fields are used within module-level code and we are executing with -fi option, then these values are populated after the table has finished loading.

2017-11-27ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detectionLv Zheng1-1/+1
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9 This patch implements a new infinite loop detection mechanism to replace the old one, it uses acpi_os_get_timer() to limit loop execution into a determined time slice. This is useful in case some hardware/firmware operations really require the AML interpreter to wait while the old mechanism could expire too fast on recent machines. The new mechanism converts old acpi_gbl_max_loop_iterations to store the user configurable value for the new mechanism in order to allow users to be still able to configure this value for acpiexec via command line. This patch also removes wrong initilization code of acpi_gbl_max_loop_iterations accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the default value is also properly tuned for acpiexec).

ACPICA commit 08b83591c0db751769d61fa889f4f50f575aeffb PinGroupConfig() is analogous to PinGroupFunction() but instead of mode (muxing), it is used to apply specific fine-grained configuration to a set of referenced pins. The format of this new resource is: PinGroupConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The PinConfigType/PinConfigValue are the same used by PinConfig() resource. Here also the combination of ResourceSource and ResourceSourceLabel is used to specify the PinGroup() this resource refers to.

ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2 PinGroupFunction() is a new resource introduced with ACPI 6.2. It is used with PinGroup() to configure specific mode for a set of pins exposed by a GPIO controller. The format of the resource is: PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource, ResourceSourceIndex, ResourceSourceLabel, ResourceUsage, DescriptorName, VendorData) The resource_source and ResourceSourceLabel fields are used to specify the PinGroup() resource referenced by PinGroupFunction(). Device (GPIO) { Name (_CRS, ResourceTemplate () { PinGroup ("group1") {2, 3} PinGroup ("group2") {4, 5} ... }) } Device (I2C) { Name (_CRS, ResourceTemplate () { PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2") }) } In the above example the PinGroupFunction() references the second PinGroup() resource (using label "mygroup2" and configures pins 4 and 5 into mode 6.

ACPICA commit a06fdba686cefccd5dd5b93b52fa0f1e3f984906 ACPI 6.2 introduced a new resource that is used to specify fine-grained configuration of a pin or set of pins used by a device. The ASL syntax of this new resource looks like: PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue, ResourceSource, ResourceSourceIndex, ResourceUsage, DescriptorName, Vendordata) {Pin List} PinConfigType is an integer with following accepted values: 0x00 (Default) - No configuration is applied to the pin 0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor 0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor 0x03 (Bias Default) - Set to default biasing 0x04 (Bias Disable) - All bias settings will be disabled 0x05 (Bias High Impedance) - Configure the pin as hi_z 0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where it drives the last value on a tristate bus 0x07 (Drive Open Drain) - Configure the pin into open drain state 0x08 (Drive Open Source) - Configure the pin into open source state 0x09 (Drive Push Pull) - Configure the pin into push-pull state 0x0a (Drive Strength) - How much the pin can supply current 0x0b (Slew Rate) - Configure slew rate of the pin 0x0c (Input Debounce) - Enable input debouncer for the pin 0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin 0x0e - 0x7f - Reserved 0x80 - 0xff - Vendor defined types The PinConfigValue depends on the type and is expressed as units suitable for that type (for example bias uses Ohms).

This is mainly for debugging purposes. But many users expect to use this facility to implement quirks to mask a specific GPE when there is a gap in Linux causing this GPE to flood. This is not working correctly because currently this facility invokes enabling/disabling counting based GPE driver APIs: acpi_enable_gpe()/acpi_disable_gpe() and the GPE drivers can still affect the count to mess up the GPE masking purposes. However, most of the IRQ chip designs allow masking/unmasking IRQs via a masking bit which is different from the enabled bit to achieve the same purpose. But the GPE hardware doesn't contain such a feature, this brings the trouble. In this patch, we introduce a software mechanism to implement the GPE masking feature, and acpi_mask_gpe() are provided to the OSPMs to mask/unmask GPEs in the above mentioned situation instead of acpi_enable_gpe()/acpi_disable_gpe().

2016-05-05ACPICA: Divergence: remove unwanted spaces for typedefLv Zheng1-14/+17
ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

ACPICA commit 16cd0872a070c8d3b16b8b13c1fc90a443a6b6fe If the definition of a control method cannot be found (probably it is in another module/SSDT), the disassembler must try to guess at the number of arguments to that method.

2016-01-01ACPICA: Events: Introduce ACPI_REG_DISCONNECT invocation to ↵Lv Zheng1-0/+1
acpi_ev_execute_reg_methods() ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8 It is likely that we should synchronously invoke _REG(DISCONNECT) only when the acpi_remove_address_space_handler() is invoked because of dependencies. If it is invoked when the object is not referenced, problem may occur if the operation region fields accessed in _REG are no longer driven by any device driver. Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of the handler availability, no return value is required for the caller. This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't introduce a real change. Lv Zheng.

ACPICA commit 918a840d27d620942e0ecb69de320bb71ea86c5a ElseIf is a macro that resolves to an Else..If in the AML byte code. This support merges an Else followed immediately by an If to an ASL ElseIf operator. Simplifies decoded ASL, especially for large Switch statements. This patch only applies to iasl, and is no-op for Linux kernel.

2015-10-22ACPICA: Debugger: Add thread ID support so that single step mode can only ↵Lv Zheng1-0/+8
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.

This patch doesn't affect Linux kernel as debugger is currently not fully functioning in the Linux kernel. And the further debugger cleanups will take care of handling debugger command signalling correctly instead of using such kind of mutexes. So it is safe to leave this patch as it is.
