From 50afaefffb4a359409d781112c88c9d3ab6ca3f1 Mon Sep 17 00:00:00 2001 From: Zephyron Date: Fri, 5 Sep 2025 14:57:58 +1000 Subject: [PATCH] feat: Enhanced Nintendo SDK crash detection and recovery system * Enhanced ARM interface backtrace logging with Nintendo SDK crash detection - Detects nnSdk module crashes and initialization-time failures - Provides detailed recovery suggestions and logging - Identifies recoverable vs non-recoverable crashes * Improved physical core crash handling - Enhanced prefetch abort and data abort recovery - Continues execution for Nintendo SDK crashes instead of suspending - Better logging for crash analysis and debugging * Expanded SVC exception handling - Added Nintendo SDK-specific crash recovery logic - Enhanced general crash recovery for low-address and assertion failures - Improved UE4 crash handling integration * Updated Horizon OS version to 20.4.0 - Updated HOS_VERSION_MINOR from 1 to 4 - Updated HOS_VERSION_MICRO from 5 to 0 - Updated version hash and display strings accordingly * Fixed Vulkan turbo mode performance metrics - Added proper type casting for execution time comparisons - Prevents potential integer overflow issues Signed-off-by: Zephyron --- src/core/arm/arm_interface.cpp | 36 ++++++++++++++ src/core/hle/api_version.h | 10 ++-- src/core/hle/kernel/physical_core.cpp | 43 +++++++++++++--- src/core/hle/kernel/svc/svc_exception.cpp | 49 +++++++++++++++++++ .../renderer_vulkan/vk_turbo_mode.cpp | 4 +- 5 files changed, 128 insertions(+), 14 deletions(-) diff --git a/src/core/arm/arm_interface.cpp b/src/core/arm/arm_interface.cpp index 5dc7e5d59..0005f3216 100644 --- a/src/core/arm/arm_interface.cpp +++ b/src/core/arm/arm_interface.cpp @@ -18,9 +18,45 @@ void ArmInterface::LogBacktrace(Kernel::KProcess* process) const { "Offset", "Symbol");
