ACPICA commit c23034a3a09d5ed79f1827d51f43cfbccf68ab64 A regression was reported to the shift offset >= width of type. This patch fixes this issue. BZ 1270.

2016-05-05ACPICA: Hardware: Add optimized access bit width supportLv Zheng1-2/+47
ACPICA commit c49a751b4dae7baec1790748a2b4b6e8ab599f51 For Access Size = 0, it actually can use user expected access bit width. This patch implements this. Besides of the ACPICA upstream commit, this patch also includes a fix fixing the issue reported by the FreeBSD community. The old register descriptors are translated in acpi_tb_init_generic_address() with access_width being filled with 0. This breaks code in acpi_hw_get_access_bit_width() when the registers are 16-bit IO ports and their bit_width fields are filled with 16. The rapid fix is meant to make code written for acpi_hw_get_access_bit_width() regression safer before the issue is correctly fixed from acpi_tb_init_generic_address().

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.

2016-04-05ACPICA: Namespace: Reorder \_SB._INI to make sure it is evaluated before ↵Lv Zheng1-21/+54
_REG evaluations ACPICA commit f005ee6b90d152c1f499efcca6b771a93903cb55 This patch splits \_SB._INI evaluation from device initialization code, so that it can be performed before PCI_Config _REG evaluations. This is required for the device enumeration process. Some named objects are initialized in \_SB._INI and PCI_Config _REG evaluations may use uninitialized named objects because of the order issue. This must be fixed before fixing ECDT order issue. There are existing tables allowing ECDT EC to be used for the entire device enumeration process, but the enabling of ECDT EC is done in \_SB._INI. Thus \_SB._INI must be the first control method evaluated in the device enumeration process. Normally, the order should be automatically ensured by the device enumeration process itself (for example, PCI_Config _REGs are evaluated by the PCI bus driver when the driver is probed by the enumeration process), but since the process is split on Linux (partially done in Linux, partially done in ACPICA), we need to ensure this with special logics in order to be regression safe.

support It is reported that the following commit triggers regressions: Linux commit: efaed9be998b5ae0afb7458e057e5f4402b43fa0 ACPICA commit: 31178590dde82368fdb0f6b0e466b6c0add96c57 Subject: ACPICA: Events: Enhance acpi_ev_execute_reg_method() to ensure no _REG evaluations can happen during OS early boot stages This is because that the ECDT support is not corrected in Linux, and Linux requires to execute _REG for ECDT (though this sounds so wrong), we need to ensure acpi_gbl_namespace_initialized is set before ECDT probing in order for _REG to be executed. Since we have to move "acpi_gbl_namespace_initialized = TRUE" to the initialization step happening before ECDT probing, acpi_load_tables() is the best candidate for now. Thus this patch fixes the regression by doing so. But if the ECDT support is fixed, Linux will not execute _REG for ECDT, and ECDT probing will happen before acpi_load_tables(). At that time, we still want to ensure acpi_gbl_namespace_initialized is set after executing acpi_ns_initialize_objects() (under the condition of acpi_gbl_group_module_level_code = FALSE), this patch also moves acpi_ns_initialize_objects() to acpi_load_tables() accordingly. Since acpi_ns_initialize_objects() doesn't seem to be skippable, this patch also removes ACPI_NO_OBJECT_INIT for the one invoked in acpi_load_tables(). And since the default region handlers should always be installed before loading the tables, this patch also removes useless acpi_gbl_group_module_level_code check accordingly.

ACPICA commit 8ae25b8d128b6b8509010be321ff6bf2760f3807 There is BIOS code relying on the fact that \_SB._INI should get evaluated before any other control methods. This may implies a gap in ACPICA/Linux initialization/enumeration process. Before revealing Windows true behavior by more validations, this patch only ensures \_SB._INI evaluated before any _REG control methods. This can help to make progress to other initialization order fixes. Lv Zheng.

2016-02-24ACPICA: ACPICA: Tune _REG evaluations order in the initialization stepsLv Zheng1-17/+18
ACPICA commit 77e0c7a482ac30ef857cf3c33d075e5fe5b5e449 This patch tunes _REG evaluations to be later than all table loading facilities: 1. acpi_load_tables(): _REG is currently invoked after this function. 2. acpi_ns_exec_module_code_list(): this executes module level code, the execution should be a part of the table loading while we currently support this in a deferred way. 3. acpi_ns_initialize_objects(): this parses Region/Field/Buffer/Package where pkg_length primitive can be seen in the grammar, the parsing should be a part of the table loading while we currently support this in a deferred way. Control method evaluation should happen after loading the tables. So this patch changes the order of _REG evaluation when acpi_gbl_group_module_level_code experiment is enabled. Lv Zheng.

2016-02-24ACPICA: Tables: make default region accessible during the table loadLv Zheng2-5/+29
ACPICA commit 016b2a0917cca9cf0d40c38a1541017d9cf569dd It is proven that the default regions should be accessible during the table loading in order to execute module level AML code. This patch moves default region handler installation code earlier in order to make this happen. Note that by putting the code here, we actually allow OSPMs to override default region handlers between acpi_initialize_subsystem() and acpi_load_tables(), without the need to introduce region handler override mechanism in acpi_install_address_space_handler(). OSPMs are also couraged to check acpi_install_address_space_handler() return value to determine if acpi_remove_address_space_handler() should be invoked before installing new address space handler.

2016-01-05ACPICA: Drop Linux-specific waking vector functionsRafael J. Wysocki1-77/+19
Commit f06147f9fbf1 (ACPICA: Hardware: Enable firmware waking vector for both 32-bit and 64-bit FACS) added three functions that aren't present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(), acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(), to allow Linux to use the previously existing API for setting the platform firmware waking vector. However, that wasn't necessary, since the ACPI sleep support code in Linux can be modified to use the upstream ACPICA's API easily and the additional functions may be dropped which reduces the code size and puts the kernel's ACPICA code more in line with the upstream. Make the changes as per the above. While at it, make the relevant function desctiption comments reflect the upstream ACPICA's ones. Signed-off-by: Rafael J.

This matches the behavior of other ACPI implementations and is required to support BIOS code that depends on this behavior.
