2015-08-26ACPICA: Debugger: Cleanup debugging outputs to dump name path without ↵Lv Zheng1-1/+1
trailing underscores ACPICA commit 51a49c2fb4a73f302a6df2b8ddc1350dd261684d It is better to use unified ASL path name to interact with the developers.

2015-07-24ACPICA: Namespace: Add function to directly return normalized full pathLv Zheng1-1/+1
ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea This patch adds functions to return normalized full path instead of "external path". The external path contains trailing "_" for each name segment while the normalized full path doesn't contain the trailing "_". Currently this function is used by the method tracing users to specify a none trailing "_" attached name path. Lv Zheng. Note that we need to validate and switch all Linux kernel acpi_get_name() users to use the new name type before removing the old name type from ACPICA.

2013-01-10ACPICA: Cleanup indentation to reduce differences between Linux and ACPICA.Lv Zheng1-3/+3
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.

2013-01-10ACPICA: Cleanup source to reduce differences between Linux and ACPICA.Lv Zheng1-1/+0
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.

2010-07-07ACPICA: Performance enhancement for namespace search and accessAlexey Starikovskiy1-113/+0
This change enhances the performance of namespace searches and walks by adding a backpointer to the parent in each namespace node. On large namespaces, this change can improve overall ACPI performance by up to 9X. Adding a pointer to each namespace node increases the overall size of the internal namespace by about 5%, since each namespace entry usually consists of both a namespace node and an ACPI operand object.
