acpica-sys
Builds acpica, and has bindings to it. To actually use most of it, various symbols will need to be provided, described in section 9 of the ACPICA reference manual.
This is a fork of the existing acpica-sys crate with minor modifications:
- Use GCC
- Modified build
- More recent acpica sources
Check https://crates.io/crates/libacpica for more details.
Updating ACPICA sources
Some steps that might be useful to follow:
- Download new sources from https://acpica.org/downloads
- Rename acpica to acpica-old
- Unpack new acpica sources, rename folder to acpica
cp acpica-old/source/include/platform/acnrk.h acpica/source/include/platform/acnrk.h
- Include the acnrk header file inside
acenv.h
in the platform list:
Should look like this:
#if defined(NRK)
#include "acnrk.h"
#elif defined(_LINUX) || defined(__linux__)
#include "aclinux.h"
mv src/raw64.rs src/raw64.bak.rs
bash update-bindings.sh
(Make sure rust-bindgen is installed for this step)- Inspect
raw64.rs
see if it approximately representssrc/raw64.bak.rs
file. - Switch whatever project uses this to new version of the crate and see if it compiles
rm src/raw64.bak.rs
rm -rf acpica-old
Some issues that can be expected and what to do about them:
- Compilation error due to __va_list_tag, AcpiOsVprintf etc. -> Just remove those definitons.
- Compilation error
error[E0433]: failed to resolve: maybe a missing crate std?
-> Replace with core, or remove those definiton if unwanted. error[E0308]: mismatched types expected i32, found u32
: Make sure UINT8, UINT32, UINT64 map to u8, u32, u64 respectively (and not i8, i32, i64).- Linker throws multiple definition of a symbol errors:
| = note: ld: ./target/x86_64-nrk/debug/deps/liblibacpica-e827d49529440c52.rlib(utglobal.o):(.data+0x0): multiple definition of `AcpiGbl_FixedEventInfo'; ./target/x86_64-nrk/debug/deps/liblibacpica-70ca8cf5bc7406ee.rlib(utglobal.o):(.data+0x0): first defined here
Some older version of libacpica creeped in through a transitive dependency (e.g., rust-topology). Clone rust-topology locally and use update libacpica there or use a cargo patch section to override.
- Linker error looking for libc functions?
| = note: ld: ./target/x86_64-nrk/debug/deps/liblibacpica-1986a2fed1aa7eb7.rlib(utdebug.o): in function `AcpiDebugPrint':
| utdebug.c:(.text+0x169): undefined reference to `strlen'
Check compile time defines for ACPI_USE_STANDARD_HEADERS
and ACPI_USE_SYSTEM_CLIBRARY
