Hello ReactOS Team and Community,
I would like to share a successful build and execution report of ReactOS 0.4.17 compiled from source on Debian 12 (Linux Kernel 6.1.0-52-amd64) and tested inside VirtualBox 5.2.44.
--- ### 🛠️ Build Environment & Toolchain: * Host OS: Debian 12 (Bookworm) - Linux Kernel 6.1.0-52-amd64 * Host CPU: Intel Core (11th/12th Gen Tiger Lake/Alder Lake architecture) * Build Environment: RosBE-Unix 2.2.1 * Compiler Toolchain: i686-w64-mingw32-gcc (GNU 8.4.0), CMake, Ninja * Source Version: ReactOS 0.4.17-dev (Build 20260819-0.4.17-dev-680-gef8bcd3) * Build Status: 11,231 / 11,231 targets built with 0 errors (ninja bootcd & ninja livecd).
--- ### ⚙️ Hypervisor & Host Setup (VirtualBox 5.2.44 on Linux 6.1): To achieve full virtualization stability on modern Linux 6.1 and 11th/12th Gen Intel CPUs: 1. vboxdrv Kernel Port: - Migrated to mmap_lock and modern 7-argument get_user_pages_remote. - Used module .bss heap (RTMEMALLOC_EXEC_HEAP) with PTE RWX mapping to satisfy 32-bit ELF relocations for VMMR0.r0. 2. Kernel / Boot Parameters: - clearcpuid=smap,smep: Prevents Ring-0 user-pointer faults in the EMT execution loop. - ibt=off: Disables Intel Indirect Branch Tracking (avoids #CP hardware traps). - randomize_kstack_offset=0: Fixes VERR_INVALID_STATE (-79) caused by kernel stack randomization.
--- ### 🖥️ Guest OS Test Results (ReactOS-Dev 0.4.17): * Installation: Formatted 20 GB VDI drive (FAT) and completed graphical setup without any errors. * Video & GDI: 32-bit True Color rendering is crisp, with no GDI alpha-blending icon glitches. * Audio: Intel AC'97 emulation works natively out of the box with clear startup chime. * Guest Additions: VirtualBox Guest Additions (5.0.40) installed cleanly: - Full HD (1920x1080) widescreen resolution. - Seamless mouse pointer integration. - No "Cannot load boot driver" warnings during FreeLdr boot.
Everything is stable, fast, and fully functional. Thank you for your continued hard work on this amazing project!
Best regards, Adrián
