From 819778f292ee4e1294603b98662e083e49e23463 Mon Sep 17 00:00:00 2001 From: salmonik Date: Sat, 1 Aug 2026 19:52:05 +0200 Subject: rsnix v0.5.0: graphics layer + cursor compositor MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The first visible GUI surface: real rect primitives, a single shadow→display push path, and an on-screen mouse cursor that can never race the text surface. gop: - fill_rect + push_rect(x,y,w,h): every raster op rasterises into the RAM shadow, then push_rect copies the rect to the display (write-only, still never read) and composites the cursor on top. blit_glyph and scroll shifts now route through it. - cursor overlay: 12x16 pointer (const-fn built from column lists) drawn white with a black offset outline; position in one AtomicU64 (x:high 32, y:low 32) — unpack masks the low word (a bare 'as usize' cast is a no-op on 64-bit). The cursor never enters the shadow, so erasing is just a shadow push of the old rect. - cursor_redraw after scroll shifts and once at spawn (the vt diff never re-blits idle cells). cursor task (task 2, spawned at boot when a mouse is present): - owns the PS/2 ring; polls every 10 ms, moves the cursor (clamped), tracks buttons, and forwards every event to a task's queue when 'mouse ' armed it (the window-manager input path). - /dev/mouse is now a position device (x/y/buttons snapshot); 'mouse' watches the cursor live (prints on change); 'cursor' prints one-shot state; 'gfx' draws a status-bar demo; 'gfx check' is an in-kernel pixel self-test (shadow readback, display readback, cursor overlay purity) — PASS/FAIL per stage. Tests (headless QEMU + monitor injection): - make test-gfx (new): all four compositor checks PASS. - make test-mouse (rewritten): cursor tracks mouse_move deltas, buttons ride along, /dev/mouse snapshot, live watch, real-event queue routing. - make test-msg: task numbering shifted (cursor is task 2; msgrecv is task 3) — updated, still PASS. - make test-disk regression re-passes. 0 build warnings. --- rsdos/src/main.rs | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'rsdos') diff --git a/rsdos/src/main.rs b/rsdos/src/main.rs index fc47c82..13923ea 100644 --- a/rsdos/src/main.rs +++ b/rsdos/src/main.rs @@ -219,6 +219,11 @@ pub unsafe extern "efiapi" fn efi_main(image_handle: Handle, system_table: *mut } rsnix::serial_println!("boot: entering shell"); + if rsnix::ps2::mouse_present() { + rsnix::cursor::spawn(); + } else { + rsnix::serial_println!("cursor: no mouse — overlay disabled"); + } shell::run(); } -- cgit v1.2.3
