- -### 2. NT-compatible from the ground up - -Over the decades of development, ACPICA has accumulated a lot of workarounds for -AML expecting NT-specific behaviors, and is still missing compatibility in a lot -of critical aspects. - -uACPI, on the other hand, is built to be natively NT-compatible without extra -workarounds. - -Some specific highlights include: -- Reference objects, especially multi-level reference chains -- Implicit cast semantics -- Object mutability -- Named object resolution, especially for named objects inside packages - -### 3. Fundamental safety - -uACPI is built to always assume the worst about the AML byte code it's executing, -and as such, has a more sophisticated object lifetime tracking system, as well -as carefully designed handling for various edge-cases, including race conditions. - -Some of the standard uACPI test cases crash both ACPICA, and the NT AML -interpreters. - -While a permanent fuzzing solution for uACPI is currently WIP, it has already -been fuzzed quite extensively and all known issues have been fixed. - -### 4. No recursion - -Running at kernel level has a lot of very strict limitations, one of which is a -tiny stack size, which can sometimes be only a few pages in length. - -Of course, both ACPICA and uACPI have non-recursive AML interpreters, but there -are still edge cases that cause potentially unbounded recursion. - -One such example are the dynamic table load operators from AML -(`Load`/`LoadTable`): these cause a linear growth in stack usage per call in -ACPICA, whereas in uACPI these are treated as special method calls, -and as such, don't increase stack usage whatsoever. - -### More detailed overview -Expressions within package: -```asl -Method (TEST) { - Local0 = 10 - Local1 = Package { Local0 * 5 } - Return (DerefOf(Local1[0])) -} - -// ACPICA: AE_SUPPORT, Expressions within package elements are not supported -// Windows, uACPI: Local0 = 50 -Local0 = TEST() -``` - -Packages outside of a control method: -```asl -// ACPICA: internal error -// Windows, uACPI: ok -Local0 = Package { 1 } -``` - -Reference rebind semantics: -```asl -Local0 = 123 -Local1 = RefOf(Local0) - -// ACPICA: Local1 = 321, Local0 = 123 -// Windows, uACPI: Local1 = reference->Local0, Local0 = 321 -Local1 = 321 -``` - -Increment/Decrement: -```asl -Local0 = 123 -Local1 = RefOf(Local0) - -// ACPICA: error -// Windows, uACPI: Local0 = 124 -Local1++ -``` - -Multilevel references: -```asl -Local0 = 123 -Local1 = RefOf(Local0) -Local2 = RefOf(Local1) - -// ACPICA: Local3 = reference->Local0 -// Windows, uACPI: Local3 = 123 -Local3 = DerefOf(Local2) -``` - -Implict-cast semantics: -```asl -Name (TEST, "BAR") - -// ACPICA: TEST = "00000000004F4F46" -// Windows, uACPI: TEST = "FOO" -TEST = 0x4F4F46 -``` - -Buffer size mutability: -```asl -Name (TEST, "XXXX") -Name (VAL, "") - -// ACPICA: TEST = "LONGSTRING" -// Windows, UACPI: TEST = "LONG" -TEST = "LONGSTRING" - -// ACPICA: VAL = "FOO" -// Windows, UACPI: VAL = "" -VAL = "FOO" -``` - -Returning a reference to a local object: -```asl -Method (TEST) { - Local0 = 123 - - // Use-after-free in ACPICA, perfectly fine in uACPI - Return (RefOf(Local0)) -} - -Method (FOO) { - Name (TEST, 123) - - // Use-after-free in ACPICA, object lifetime prolonged in uACPI (node is still removed from the namespace) - Return (RefOf(TEST)) -} -``` - -CopyObject into self: -```asl -Method (TEST) { - CopyObject(123, TEST) - Return (1) -} - -// Segfault in ACPICA, prints 1 in uACPI -Debug = TEST() - -// Unreachable in ACPICA, prints 123 in uACPI -Debug = TEST -``` - -There's even more examples, but this should be enough to demonstrate the fundamental differences in designs. - -## Integrating into a kernel - -### 1. Add uACPI sources & include directories into your project - -#### If you're using CMake -Simply add the following lines to your cmake: -```cmake -include(uacpi/uacpi.cmake) - -target_sources( - my-kernel - PRIVATE - ${UACPI_SOURCES} -) - -target_include_directories( - my-kernel - PRIVATE - ${UACPI_INCLUDES} -) -``` - -#### If you're using Meson -Add the following lines to your meson.build: -```meson -uacpi = subproject('uacpi') - -uacpi_sources = uacpi.get_variable('sources') -my_kernel_sources += uacpi_sources - -uacpi_includes = uacpi.get_variable('includes') -my_kernel_includes += uacpi_includes -``` - -#### Any other build system -- Add all .c files from [source](source) into your target sources -- Add [include](include) into your target include directories - -### 2. Implement/override platform-specific headers - -uACPI defines all platform/architecture-specific functionality in a few headers inside [include/uacpi/platform](include/uacpi/platform) - -All of the headers can be "implemented" by your project in a few ways: -- Implement the expected helpers exposed by the headers -- Replace the expected helpers by your own and override uACPI to use them by defining the respective `UACPI_OVERRIDE_X` variable. -In this case, the header becomes a proxy that includes a corresponding `uacpi_x.h` header exported by your project. - -Currently used platform-specific headers are: -- [arch_helpers.h](include/uacpi/platform/arch_helpers.h) - defines architecture/cpu-specific helpers & thread-id-related interfaces -- [compiler.h](include/uacpi/platform/compiler.h) - defines compiler-specific helpers like attributes and intrinsics. -This already works for MSVC, clang & GCC so you most likely won't have to override it. -- [atomic.h](include/uacpi/platform/atomic.h) - defines compiler-specific helpers for dealing with atomic operations. - Same as the header above, this should work out of the box for MSVC, clang & GCC. -- [libc.h](include/uacpi/platform/libc.h) - an empty header by default, but may be overriden by your project -if it implements any of the libc functions used by uACPI (by default uACPI uses its -own implementations to be platform-independent and to make porting easier). The -internal implementation is just the bare minimum and not optimized in any way. -- [types.h](include/uacpi/platform/types.h) - typedefs a bunch of uacpi-specific types using the `stdint.h` header. You don't have to override this -unless you don't provide `stdint.h`. -- [config.h](include/uacpi/platform/config.h) - various compile-time options and settings, preconfigured to reasonable defaults. - -### 3. Implement kernel API - -uACPI relies on kernel-specific API to do things like mapping/unmapping memory, writing/reading to/from IO, PCI config space, and many more things. - -This API is declared in [kernel_api.h](include/uacpi/kernel_api.h) and is implemented by your kernel. - -### 4. Initialize uACPI - -That's it, uACPI is now integrated into your project. - -You should proceed to initialization. -Refer to the [uACPI page](https://wiki.osdev.org/uACPI) on osdev wiki to see a -snippet for basic initialization, as well as some code examples of how you may -want to use certain APIs. - -All of the headers and APIs defined in [uacpi](include/uacpi/) are public and may be utilized by your project. -Anything inside [uacpi/internal](include/uacpi/internal) is considered private/undocumented and unstable API. - -## Developing and contributing - -Most development work is fully doable in userland using the test runner. - -### Setting up an IDE: - -Simply open [tests/runner/CMakeLists.txt](tests/runner/CMakeLists.txt) in your favorite IDE. - -For Visual Studio: -``` -cd tests\runner && mkdir build && cd build && cmake .. -``` - -Then just simply open the .sln file generated by cmake. - -### Running the test suite: -``` -./tests/run_tests.py -``` - -If you want to contribute: -- Commits are expected to be atomic (changing one specific thing, or introducing one feature) with detailed description (if one is warranted for), an S-o-b line is welcome -- Code style is 4-space tabs, 80 cols, the rest can be seen by just looking at the current code - -**All contributions are very welcome!** - -## Notable projects using uACPI & performance leaderboards - -| Project | Description | (qemu w/ Q35 + KVM) ops/s | CPU | -|--- |--- |--- |--- | -| [proxima](https://github.com/proxima-os/) | Unix-like microkernel-based operating system with uACPI running in userspace | 10,454,158 | AMD Ryzen 9 9950X3D | -| [ilobilix](https://github.com/ilobilo/ilobilix) | Yet another monolithic Linux clone wannabe.
