t3hn3rd	36ec7bfdb6	refactor: move program registration from kernel to progmanager ... - Remove diskcmd, diskutil, notepad, partcmd, volcmd init calls and uses from kernel.pas — these are programs, not kernel subsystems. - Move their initialization into progmanager.init() alongside the other baked-in programs (md5sum, base64_prog, dhclient, etc.). - Remove diskcmd, diskutil, notepad from kernel's uses clause. - Add a splash.update() call for the auto-mount volumes step. - Suppress FPC warnings in compile_sources.sh (-v0e instead of -v0ew).	2026-03-07 20:39:43 +00:00
t3hn3rd	6c3c0e63d5	fix: Rebase borked kernel.pas - added missing deps	2026-03-07 20:31:38 +00:00
t3hn3rd	df71c59aea	feature: add boot splash screen with embedded TGA logo ... - New splash unit (src/prog/splash.pas) displays a centered logo, progress bar and status label during kernel boot. Manually drives LVGL rendering + video.Flush since gfxd isn't running yet. - Embed img/asuro.tga into the kernel via NASM incbin stub (src/stub/splash_tga.asm), assembled in compile_stub.sh. - Build an lv_image_dsc_t at runtime from the decoded TGA pixel data and display it at 50% scale using lv_image_set_scale(128). - Move LVGL init earlier in kernel.pas (right after video enable) so the splash screen is available before VFS/drivers/network init. - Sprinkle splash.update() calls throughout kmain to show boot progress (VFS → drivers → buses → network → tests → desktop). - Fix targa.pas parser: rename Magic→IDLength, remove erroneous Data pointer field, compute pixel offset correctly (buffer+18+IDLength), advance source pointer per pixel, handle bottom-to-top origin flip. - Unit tests moved before desktop.init; splash.teardown called at 100% just before handing off to the desktop environment.	2026-03-07 20:20:00 +00:00
t3hn3rd	97244a2b95	Rebase: Changes made to conform with rebase on develop	2026-03-07 20:17:24 +00:00
t3hn3rd	ecca496978	fix: show live GPU/resolution info in System Information ... - desktop: Resolution/Graphics fields now read from video frontbuffer and gpu.activeDriverName instead of static multiboot/hardcoded values - gpu: markAvailable sets ActiveName when no driver is active yet, so the initial VBE boot driver is reported before any setMode call - kernel: whitespace cleanup	2026-03-07 20:16:26 +00:00
t3hn3rd	e52b4a9763	feature: GPU driver framework with BGA, V86 monitor, and runtime resolution switching ... - GPU Framework (gpu.pas): Priority-ordered GPU driver registry with mode-change callback system. Drivers register with a priority (lower = tried first). After successful setMode, fires registered callbacks in order (video → LVGL → desktop) for fully decoupled resolution updates. - BGA Driver (bga.pas): Bochs Graphics Adapter via drivermanagement PCI auto-detection (class=$03 subclass=$00 wildcard). Programs display via I/O ports $01CE/$01CF, reads framebuffer from PCI BARs with VMware SVGA fallback. Supports arbitrary resolutions (1920x1080, 2560x1440, etc). - SETRES Command (setres.pas): Runtime resolution switching — just calls gpu.setMode; video reinit, LVGL buffer realloc, and desktop relayout all fire automatically via GPU mode-change callbacks. - VESA/VBE: Registered as GPU fallback driver (priority 50), uses V86 INT 10h for VBE mode switching. - TSS: Fix SS0 from $08 (code segment) to $10 (data segment); add set_esp0/get_esp0 helpers for V86 ring-0 stack management. - VMM: Add map_page_user() for identity-mapping first 4MB with User bit (required for V86 IVT/BDA/video ROM access). - Desktop: relayout procedure + GPU callback registration for automatic dock/watermark repositioning on resolution change. - V86 Monitor (v86.pas): Full Virtual 8086 mode monitor for executing real-mode BIOS interrupts from protected mode. Naked GPF handler with instruction emulation (INT, IRET, CLI, STI, PUSHF/POPF, IN/OUT, HLT, 0x66 prefix for 32-bit variants). Thunk-based entry via IRET into VM86. - Kernel init order: gpu.init → video.init → vesa.init → bga.init; drivermanagement.init moved earlier (before video) so PCI scan detects BGA before first use.	2026-03-07 20:16:25 +00:00

t3hn3rd	738e5828f6	Fix PS/2 mouse ISR blocking; convert USB polling & GFX refresh to processes; remove dead scheduler ... PS/2 Mouse: - Fix ISR spin-blocking by reading port $60 directly with inb() instead of calling mouse_read(), which uses mouse_wait_long (100k iterations) and would stall the interrupt handler waiting for the next packet byte. Timer (PIT): - Increase PIT frequency from ~1024 Hz to ~8 kHz (divisor 1193 -> 149) for more granular timer ticks. Graphics Refresh: - Replace timer-hook-driven rendering (driver/timers/graphicsrefresh) with a dedicated 'gfxd' process that runs a continuous render loop, keeping the vCPU active to avoid NEM/Hyper-V pause-loop descheduling. - Move uidebug from driver/video/ to prog/. - Update FPS calculation to account for 8 kHz tick rate. USB Hotplug: - Replace timer-hook-driven polling (driver/timers/usbhotplug) with a dedicated 'usbd' daemon process that sleeps 1s between poll cycles. - Add bounds check in usbcore.usb_check_hotplug for empty HC list. Cleanup: - Remove old scheduler unit (superseded by processmanager/contextswitcher). - Remove tss unit and tss.init() call from kernel. - Remove unused syslog import from contextswitcher. - Reduce BASE_QUANTUM from 8 to 5.	2026-03-07 00:29:38 +00:00

The kernel main procedure now registers both timer hooks and enters an idle STI/HLT loop (kernel.yield), allowing the CPU to sleep between interrupts instead of busy-spinning.
