Introduce boot.mgr - a self-registering, dependency-ordered boot
initialization framework with barrier-based phasing and glob pattern
matching. Units now declare their own init procedures and dependencies
via registerBoot()/registerBarrier() in their initialization sections,
boot.mgr.run() topologically sorts and executes them.
- Add src/boot/boot.mgr.pas with topoSort, glob matching, barrier
two-pass algorithm, and boot tree printer
- Gut src/asuro.pas (kmain): now just stores multiboot info, calls
System.init(), boot.mgr.run, and yield()
- Add initialization sections with registerBoot() to 53 existing units
- Add new units: core.pas, test.pas, driver.storage.boot.pas,
app.wasm.pas, app.bsod.pas (factored out of asuro.pas)
- Define 9 barrier phases: immediate -> early -> middle -> storage ->
bus -> device -> bus.late -> late -> final
- Fix xHCI ISR: exclude PRC/WRC from PORTSC change bit clearing to
prevent race with port reset busy-wait
- Fix driver.bus.usb.core fire_completion_hooks: guard against uint32
underflow when CompletionHookCount = 0
- Move auto_mount_volumes from device barrier to late barrier so it
runs after PCI scan discovers storage controllers
- Add toolchain/compile_initcalls.sh for boot entry extraction
- Add Boot Registration sections to all 51 doc files; create 4 new
doc files; rewrite boot.mgr.md; update mkdocs.yml nav
- 5-phase VFS architecture overhaul (path resolution, dir cache, watch/notify,
symlinks, async API)
- Add character/block device node layer with /dev/null and /dev/zero built-ins
- RegisterDevice() API for custom device nodes with read/write/size callbacks
- Merge TOpenMode + TWriteMode into single TOpenMode enum
(omRead, omWrite, omCreate, omReadWrite, omStream)
- Add stream write support: WriteFile/WriteFileAsync now accept omStream handles
with auto-advancing offset for both device and volume FDs
- Add PPWriteOffsetHook type and writeOffsetCallback field to TFilesystem
- Add PPReadOffsetHook-based streaming reads for FAT32 and ISO9660
- Update all callers (notepad, edit, inio, wasm runner, filepicker, filedispatch,
vterminal, stdio) to new 2-param OpenFile API
- 77 unit tests (0 failures) covering path ops, dir cache, symlinks, watch,
device nodes, and stream read/write
- Add doc/vfs.md — comprehensive public VFS API documentation
Introduce core.panic, a new architecture-agnostic kernel panic engine
with a pre-allocated LVGL BSOD screen. The screen and all widgets are
created at init time so that zero LVGL allocation occurs at panic time.
Layout features:
- Top banner with decoded teapot TGA image (128x128) and title/subtitle
- Two-column content area with dark semi-transparent cards:
- Left: Fault Details, CPU Registers, Process Info, System Info
- Right: Call Stack (full height)
- Pastel red background (#7A2828), monospace text for data sections
Key changes:
- Add core.panic.pas with pre-built BSOD screen, register/trace/system
info formatting, hex conversion helpers, and syslog fallback
- Add arch.x86.panic.pas as the x86 bridge: packs interrupt registers
into a TRegisterSnapshot and calls core.panic.panic()
- Simplify all 19 x86 fault handlers to one-liner panic calls
- Remove legacy BSOD code from arch.x86.util.pas
- Add teapot.tga (256x256) embedded via splash_tga.asm
- Add LVGL bindings: lv_refr_now, lv_image_create, lv_image_set_src,
lv_image_set_scale, lv_image_set_inner_align, and style helpers
- Wire up panic init and test command in asuro.pas
