From 75c8044fb38051713000e0d151852f5f9614f77b Mon Sep 17 00:00:00 2001 From: Lv Zheng Date: Wed, 19 Dec 2012 05:36:49 +0000 Subject: ACPICA: Cleanup updated comments. 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.

This patch decreases 170 lines of 20121018 divergence.diff. This patch updates ACPICA codes surrounded by some disabled build options so that the source code diff between Linux and ACPICA can be reduced.

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 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 314 lines of 20121018 divergence.diff. ACPICA core uses ()'s on return statements. This is a known and committed differences from Linux standard coding style.

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. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

Some ASL compilers allow 64-bit constants within a 32-bit table (DSDT version == 1). When encountered, emit a warning that the constant will be truncated to 32 bits. This is potentially a serious problem in the ACPI table(s). Signed-off-by: Bob Moore Signed-off-by: Lv Zheng 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 44 lines of 20121114 divergence.diff. There are naming conflicts between Linux and ACPICA on table handlers. This patch cleans up this conflicts to reduce the source code diff between Linux and ACPICA. Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

48ffb94f9e6f9b11c26884f26199e3d51bb22e54 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Fri, 25 Jan 2013 05:41:00 +0000 Subject: ACPICA: AcpiGetSleepTypeData: Allow \_Sx to return either 1 or 2 integers Although the ACPI spec defines the \_Sx objects to return a package containing one integer, most BIOS code returns two integers and the previous code reflects that. However, we also need to support BIOS code that actually implements to the ACPI spec, and this change implements this. Signed-off-by: Bob Moore Signed-off-by: Lv Zheng Signed-off-by: Rafael J.

Often, the NOOP opcode is used as padding for packages that are changed dynamically by the BIOS. When disassembled, these NOOPs will cause syntax errors. This option causes the disassembler to ignore the NOOP opcode, and it also causes the compiler to ignore NOOP statements as well.
