ACPICA commit 4b0e043386c7e698bea9e862f60a388647f56622 Previously, there was a mixup where _NIG required one parameter and _NIH required zero parameters. This changes swaps these parameter requirements. Now this change requires _NIH to be called with one parameter and _NIG requires zero.

operators ACPICA commit cd66d0a50fdc9cc4dcd998e08e7aa3c4154bea2d Disassembler is intended to emit existing ASL code as-is. Therefore, error messages emitted during disassembly should be ignored or handled in a way such that the disassembler can continue to parse the AML. This change ignores AE_ALREADY_EXISTS errors during the deferred Op parsing for create operators in order to complete parsing ASL termlists.

The check carried out by acpi_any_gpe_status_set() is not precise enough for the suspend-to-idle implementation in Linux and in some cases it is necessary make it skip one GPE (specifically, the EC GPE) from the check to prevent a race condition leading to a premature system resume from occurring. For this reason, redefine acpi_any_gpe_status_set() to take the number of a GPE to skip as an argument.

Commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") overlooked the fact that fixed events can wake up the system too and broke RTC wakeup from suspend-to-idle as a result. Fix this issue by checking the fixed events in acpi_s2idle_wake() in addition to checking wakeup GPEs and break out of the suspend-to-idle loop if the status bits of any enabled fixed events are set then.

2020-02-16ACPICA: Enable sleep button on ACPI legacy wakeAnchal Agarwal1-0/+12
ACPICA commit 9383f5b01091e432c05f802a57edc20d329eec1f Hibernation (S4) is triggered in a guest when it recieves a sleep trigger from the hypervisor. When the guest resumes from this power state, it does not see the sleep_enabled bit. In otherwords, the sleep button is not enabled on waking from an S4 state. This causes subsequent invocation of sleep state to fail in the guest. Fix this problem by enabling the sleep button in ACPI legacy wake.

2019-12-20ACPICA: Dispatcher: always generate buffer objects for ASL create_field() ↵Maximilian Luz3-3/+12
operator ACPICA commit 79a466b64e6af36cc83102f05915e56cb7dd89ab According to table 19-419 of the ACPI 6.3 specification, buffer_fields created using the ASL create_field() Operator have been treated as integers if the buffer_field is small enough to fit inside of an ASL integer (32-bits or 64-bits depending on the definition block revision). If they are larger, buffer fields are treated as ASL Buffer objects. However, this is not true for other AML interpreter implementations. It has been discovered that other AML interpreters always treat buffer fields created by create_field() as a buffer regardless of the length of the buffer field. More specifically, the Microsoft AML interpreter always treats buffer fields created by the create_field() operator as buffer. ACPICA currently does this only when the field size is larger than the maximum integer width. This causes problems with AML code shipped in Microsoft Surface devices. More details: The control methods in these devices determine the success of an ASL control method execution by examining the type resulting from storing a buffer field created by a create_field() operator. On success, a Buffer object is expected, on failure an Integer containing an error code. This buffer object is created with a dynamic size via the create_field() operator. Due to the difference in behavior, Buffer values of small size are however converted to Integers and thus interpreted by the control method as having failed, whereas in reality it succeeded. Below is an example of a control method called TEST that illustrates this behavior. Method (CBUF) // Create a Buffer field { /* * Depending on the value of RAND, ACPICA interpreter will treat * BF00 as an integer or buffer. */ create_field (BUFF, 0, RAND, BF00) return (BF00) } Method (TEST) { /* * Storing the value returned by CBUF to local0 will result in * implicit type conversion outlined in the ACPI specification. * * ACPICA will treat local0 like an ASL integer if RAND is less * than or equal to 64 or 32 (depending on the definition_block * revision). If RAND is greater, it will be treated like an ASL * buffer. Other implementations treat local0 like an ASL buffer * regardless of the value of RAND. */ local0 = CBUF() /* * object_type of 0x03 represents an ASL Buffer */ if (object_type (Local0) != 0x03) { // Error on ACPICA if RAND is small enough } else { /* * Success on APICA if RAND is large enough * Other implementations always take this path because local0 * is always treated as a buffer. */ } } This change prohibits the previously mentioned integer conversion to match other AML interpreter implementations (Microsoft) that do not conform to the ACPI specification.

2019-12-20ACPICA: Disassembler: create buffer fields in ACPI_PARSE_LOAD_PASS1Erik Kaneda2-1/+22
ACPICA commit 29cc8dbc5463a93625bed87d7550a8bed8913bf4 create_buffer_field is a deferred op that is typically processed in load pass 2. However, disassembly of control method contents walk the parse tree with ACPI_PARSE_LOAD_PASS1 and AML_CREATE operators are processed in a later walk. This is a problem when there is a control method that has the same name as the AML_CREATE object. In this case, any use of the name segment will be detected as a method call rather than a reference to a buffer field. If this is detected as a method call, it can result in a mal-formed parse tree if the control methods have parameters. This change in processing AML_CREATE ops earlier solves this issue by inserting the named object in the ACPI namespace so that references to this name would be detected as a name string rather than a method call.

2019-10-29ACPICA: debugger: add field unit support for acpi_db_get_next_tokenErik Schmauss1-0/+15
ACPICA commit d509afa88e9415f13a3283c38ce9ee034634ae24 Since field unit data output from the debugger are now surrounded by braces '{', support has been added to acpi_db_get_next_token to recognize strings beginning with this character as a ACPI_TYPE_FIELD_UNIT.

ACPICA commit 76ca57291d007d33087982a4b28cd1ee9bcd37a6 This helps differentiate the type of named objects between field units and buffers. In other words, without this symbol, it would be difficult to tell whether a particular named object is a buffer or a field unit.

2019-10-29ACPICA: make acpi_load_table() return table indexNikolaus Voss2-2/+8
ACPICA commit d1716a829d19be23277d9157c575a03b9abb7457 For unloading an ACPI table, it is necessary to provide the index of the table. The method intended for dynamically loading or hotplug addition of tables, acpi_load_table(), should provide this information via an optional pointer to the loaded table index. This patch fixes the table unload function of acpi_configfs.
