2015-07-01ACPICA: De-macroize calls to standard C library functionsBob Moore
ACPICA commit 3b1026e0bdd3c32eb6d5d313f3ba0b1fee7597b4 ACPICA commit 00f0dc83f5cfca53b27a3213ae0d7719b88c2d6b ACPICA commit 47d22a738d0e19fd241ffe4e3e9d4e198e4afc69 Across all of ACPICA. Replace C library macros such as ACPI_STRLEN with the standard names such as strlen. The original purpose for these macros is long since obsolete. Also cast various invocations as necessary.

2014-02-05ACPICA: Introduce acpi_get_data_full() and rework acpi_get_data()Rafael J. Wysocki
Introduce a new function, acpi_get_data_full(), working in analogy with acpi_get_data() except that it can execute a callback provided as its 4th argument right after acpi_ns_get_attached_data() has returned a success. That will allow Linux to reference count the object pointed to by *data before the namespace mutex is released so as to ensure that it will not be freed going forward until the reference to it acquired by acpi_get_data_full() is dropped.

2013-01-10ACPICA: Fix broken call depth tracing logic.Lv Zheng
This patch does not affect the generation of the Linux binary. This patch decreases 26 lines of 20121018 divergence.diff. The ACPICA uses a call depth tracing mechanism by wrapping the return statements with return macros and marking the entrance with ACPI_FUNCTION_TRACE_ macros. There are other ACPI_FUNCTION_ macros used to mark the functions not using this tracing mechanism. This patch fixes broken call depth tracing logic.

2013-01-10ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA.Lv Zheng
This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 210 lines of 20121018 divergence.diff. The ACPICA source codes uses a totally different indentation style from the Linux to be compatible with other users (operating systems or BIOS). Indentation differences are critical to the release automation. There are two causes related to the "indentation" that are affecting the release automation: 1. The ACPICA -> Linux release process is: ACPICA source -- acpisrc - hierarchy - indent -> linuxized ACPICA source -- diff -> linuxized ACPICA patch (x) -- human intervention -> linuxized ACPICA patch (o) Where 'x' means "cannot be directly applied to the Linux" 'o' means "can be directly applied to the Linux" Different "indent" version or "indent" options used in the "indent" step will lead to different divergences. The version of "indent" used for the current release process is: GNU indent 2.2.11 The options of "indent" used for the current release process is: -npro -kr -i8 -ts8 -sob -l80 -ss -ncs 2. Manual indentation prettifying work in the Linux side will also harm the automatically generated linuxized ACPICA patches, making them impossible to apply directly. This patch fixes source code differences caused by the two causes so that the "human intervention" can be reduced in the future. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 389 lines of 20121018 divergence.diff. This patch reduces source code diff caused by the simple code maintenance work: 1. Deletion of the unused include files. 2. Deletion of the deprecated codes blocks. 3. Repositioning of the code blocks. 4. Replacing the values with the well defined macros. 5. Replacing the types with the equivalent types.

This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 558 lines of 20121018 divergence.diff. This patch reduces the source code diff between Linux and ACPICA by cleaning the comments that already have been updated in ACPICA. There is no extra indentation done in this patch. Even the empty line deletions and insertions are also splitted into another cleanup patch so that this patch can be easily reviewed, and the binary differences can be held to a lowest level.

2009-04-07hwmon: Add Asus ATK0110 supportLuca Tettamanti
Asus boards have an ACPI interface for interacting with the hwmon (fan, temperatures, voltages) subsystem; this driver exposes the relevant information via the standard sysfs interface. There are two different ACPI interfaces: - an old one (based on RVLT/RFAN/RTMP) - a new one (GGRP/GITM) Both may be present but there a few cases (my board, sigh) where the new interface is just an empty stub; the driver defaults to the old one when both are present. The old interface has received a considerable testing, but I'm still awaiting confirmation from my tester that the new one is working as expected (hence the debug code is still enabled). Currently all the attributes are read-only, though a (partial) control should be possible with a bit more work.
