* rsnix v0.5.1: force the GUI canvas to 800x600 via GOP SetModesalmonik2026-08-011-3/+19
| | | | | | | | | | | | | | | | | | | The kernel used to inherit whatever GOP mode the firmware picked (QEMU/OVMF gave 1280x800). Now every surface derives from a fixed 800x600 canvas: - uefi: typed EfiGopQueryMode/SetMode/GetMode fn pointers in GraphicsOutputProtocol (were raw *mut c_void, never called). - gop::select_gop_mode: scan the mode list for an exact 800x600 (32-bit BGR/RGB only, the driver assumes 4 Bpp), SetMode it; fall back to the smallest mode that fits the canvas, then to the firmware's choice. SetMode may move both the mode info pointer and the framebuffer base, so both are re-read after the switch. Boot log: 'gop: mode 3 selected — 800x600 (was 1280x800)'. - tests: relative assertions are resolution-agnostic; test-gfx and test-mouse had a boot-log race (shell line prints before the cursor task line) — now wait for the cursor line instead of grepping once. All four suites pass at 800x600. 0 build warnings.

* power: proper shutdown via UEFI ResetSystem (ACPI S5)salmonik2026-07-311-2/+32
| | | | | | | | | | | - uefi.rs: full EFI_RUNTIME_SERVICES layout with reset_system at index 10 (spec order); EfiResetSystem type + RESET_* constants - power.rs: stash the runtime-services table pre-EBS; poweroff() calls ResetSystem(EfiResetShutdown) — still callable after ExitBootServices because we never call SetVirtualAddressMap, so the pointers keep working with physical addresses; falls back to the hlt loop - shell: 'poweroff' and 'exit' shut the machine down (QEMU exits), 'halt' keeps the plain hlt loop
* rsnix: memory management — free-list heap, bitmap pages, paging adoptionsalmonik2026-07-311-5/+35
| | | | | | | | | | | | | | - uefi.rs: full EfiMemoryType constants (0-14) + memory_type_name(); fix MEMORY_TYPE_LOADER_DATA from 6 to 2 per the UEFI spec - memory.rs: replace the bump allocator with a first-fit free-list heap (splitting, coalescing, 8-byte back-pointer for alignment-safe free); add a bitmap physical page allocator (heap region reserved, page-0 guard, aligned runs); grow the heap from the page allocator on demand - paging.rs: identity page-table helpers — adopt_tables() rebuilds the firmware map into our own tables (OVMF maps its tables read-only, so the firmware tree can't be modified in place) and switches CR3; map_page/unmap_page/is_mapped with 2 MB/1 GB large-page splitting - main.rs: boot self-tests for heap, pages, and paging
* restructure: rsnix kernel + shell crate + rsdos entry pointsalmonik2026-07-311-0/+289
Architecture: rs-dos/ (workspace root, was raisernics/) ├── rsnix/ — kernel lib crate (uefi, serial, gop, ps2, interrupts, memory) ├── shell/ — shell lib crate (prompt, commands, line input) ├── rsdos/ — binary crate (efi_main, init, panic handler) └── rsboot/ — future git submodule No functional changes — boots to shell prompt identically. Version auto-pulled from Cargo.toml via env!("CARGO_PKG_VERSION").
