Atmosphère is a work-in-progress customized firmware for the Nintendo Switch.
496adb0018
* Work around Clang's incomplete C++20 support for omitting typename * vapours: fix Clang error about missing return in constexpr function * stratosphere: fix call to non-constexpr strlen in constexpr function strlen being constexpr is a non-compliant GCC extension; Clang explicitly rejects it: https://reviews.llvm.org/D23692 * stratosphere: add a bunch of missing override specifiers * stratosphere: work around Clang consteval bug Minimal example: https://godbolt.org/z/MoM64v93M The issue seems to be that Clang does not consider f(x) to be a constant expression if x comes from a template argument that isn't a non-type auto template argument (???) We can work around this by relaxing GetMessageHeaderForCheck (by using constexpr instead of consteval). This produces no functional changes because the result of GetMessageHeaderForCheck() is assigned to a constexpr variable, so the result is guaranteed to be computed at compile-time. * stratosphere: fix missing require clauses in definitions GCC not requiring the require clauses to be repeated for member definitions is actually a compiler bug: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96830 Clang rejects declarations with missing require clauses. * Fix ALWAYS_INLINE_LAMBDA and parameter list relative order While GCC doesn't seem to care about the position of the always_inline attribute relative to the parameter list, Clang is very picky and requires the attribute to appear after the parameter list (and before a trailing return type) * stratosphere: fix static constexpr member variable with incomplete type GCC accepts this for some reason (because of the lambda?) but Clang correctly rejects this. |

Atmosphère is a work-in-progress customized firmware for the Nintendo Switch.
Components
Atmosphère consists of multiple components, each of which replaces/modifies a different component of the system:
- Fusée: First-stage Loader, responsible for loading and validating stage 2 (custom TrustZone) plus package2 (Kernel/FIRM sysmodules), and patching them as needed. This replaces all functionality normally in Package1loader/NX Bootloader.
- Sept: Payload used to enable support for runtime key derivation on 7.0.0.
- Exosphère: Customized TrustZone, to run a customized Secure Monitor
- Thermosphère: EL2 EmuNAND support, i.e. backing up and using virtualized/redirected NAND images
- Stratosphère: Custom Sysmodule(s), both Rosalina style to extend the kernel/provide new features, and of the loader reimplementation style to hook important system actions
- Troposphère: Application-level Horizon OS patches, used to implement desirable CFW features
