| | | | | | | | | | | | | | | | | Linux has been fixed during 20151218 release cycle by reverting wrong code in the following commit: ACPICA commit: 071eff738c59eda1792ac24b3b688b61691d7e7c Subject: Add per-table execution of module-level code, early region handlers While upstream ACPICA fixes later in the following commit: ACPICA commit: bf6cfddb4784c349f781758981b207253b5a1252 Subject: Fix for module-level-code regression introduced in 20151218 This results in the divergences and this patch is meant to reduce such divergences.

* ACPICA: Drop Linux-specific waking vector functionsRafael J. Wysocki2016-01-043-79/+27
| | | | | | | | | | | | | | | | | | | | 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.

* ACPICA: Add per-table execution of module-level codeBob Moore2016-01-012-1/+24
| | | | | | | | | | | | | | | ACPICA commit 071eff738c59eda1792ac24b3b688b61691d7e7c Execute any module-level code after each ACPI table (DSDT or SSDT) is loaded into the namespace (rather than after all AML tables have been loaded). This matches the behavior of other ACPI implementations and is required to support BIOS code that depends on this behavior.

* ACPICA: Events: Introduce ACPI_REG_DISCONNECT invocation to ↵Lv Zheng2016-01-014-16/+17
| | | | | | | | | | | | | | | | | | | | | | | 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: Events: Enhance acpi_ev_execute_reg_method() to ensure no _REG ↵Lv Zheng2016-01-017-42/+30
| | | | | | | | | | | | | | | | | | | | | | | evaluations can happen during OS early boot stages ACPICA commit 31178590dde82368fdb0f6b0e466b6c0add96c57 We can ensure no early _REG evaluations by ensuring the following rules in acpi_ev_execute_reg_method(): 1. If an address space handler is installed during early stage, _REG(CONNECT) evaluations are blocked. This is achieved using acpi_gbl_reg_methods_enabled which is renamed from acpi_gbl_reg_methods_executed. 2. If _REG(CONNECT) has never been evalauted for the region object, _REG(DISCONNECT) evaluations are blocked. This is achieved by a new region object flag: AOPOBJ_REG_CONNECTED. Note that, after applying this patch, we can ensure _REG(DISCONNECT) is always paired to _REG(CONNECT).

| | | | | | | | | | | | | | | ACPICA commit 253e3c03efc1a495d2aa61eee09ab1d0842a3dce The control method auto-serialization can interfere with existing ASL code that makes use of Mutex/Method SyncLevel support. This change makes the auto-serialization transparent to the SyncLevel support and management. David Box. Link: https://github.com/acpica/acpica/commit/253e3c03 Signed-off-by: David E.

| | | | | | | | | | | | | | | | | ACPICA commit 75c0da9e796bdf9bdd46d75f028a3e1779903214 In the error logs and debugger outputs, use new external path format that does not contain a trailing underscore. This patch takes care of acpi_ns_get_external_pathname() invocations, chaning them into acpi_ns_get_normalized_pathname(TRUE) where possible. Along with some error log fixes, the following debugger commands are fixed: resources, handlers, paths. Lv Zheng.

| | | | | | | | | | | | | The patch reduces source code differences between the Linux kernel and the ACPICA upstream so that the linuxized ACPICA 20151218 release can be applied with reduced human intervention. The pscode.c has already been out of sync for months, and it becomes more and more difficult to merge pscode.c changes, so instead of update the affected lines of pscode.c, this patch synchronizes entire pscode.c file.

| | | | | | | | | | | | | | | | | | | | The copy_to/from_user() functions don't return error codes, they return the number of bytes remaining. We had intended to return -EFUALT here.

| | | | | | | | | | | | | | | | | | | | | | This patch converts AML debugger into a loadable module. Note that, it implements driver unloading at the level dependent on the module reference count.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds /sys/kernel/debug/acpi/acpidbg, which can be used by userspace programs to access ACPICA debugger functionalities. Known issue: 1. IO flush support acpi_os_notify_command_complete() and acpi_os_wait_command_ready() can be used by acpi_dbg module to implement .flush() filesystem operation. While this patch doesn't go that far. It then becomes userspace tool's duty now to flush old commands before executing new batch mode commands.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
