From 5431b6543fb45f6c61dbb1394c918f3bc5acefae Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Tue, 29 Dec 2015 13:52:32 +0800 Subject: [PATCH 01/43] ACPICA: Linuxize: reduce divergences for 20151218 release 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 _SUB method was found to be problematic for this interface because some implementations use control methods. Therefore, it is being removed. Operations cannot be used because this interface is called during the device discovery scan and the region handlers are not fully installed at that time.

The UserTerm (method invocation) element was removed. Previously a SuperName, the lone argument now requires a new ARGP_ type.

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).

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.

Wysocki" Date: Mon, 4 Jan 2016 22:05:20 +0100 Subject: [PATCH 43/43] ACPICA: Drop Linux-specific waking vector functions 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.
