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
- Add SYM_TRASH toolbar button wired to fb_delete_cb (was missing entirely)
- Filter '.' and '..' entries in fb_collect_cb so they never appear
- Rewrite deleteFile/deleteDir/renameFile to use raw sector scanning
instead of getDirEntries linked-list indices (fixes gap mismatch)
- Handle root directory correctly (use bootRecord^.rootCluster instead
of assuming entry 0 is '.')
Removed driver.hid.mouse dependency that caused page fault on close.
Context menu now triggers via LV_EVENT_LONG_PRESSED on content rows.
Cleaned up onClose teardown ordering and removed debug syslog markers.
- Add extension-based dispatch to driver.storage.filedispatch with typed
union (variant record THandlerKind = hkMagic/hkExtension)
- Extract file-type icon constants and mapping to core.gfx.fileicons
- Add core.search utility (getFileExtension, fmtFileSize, sortStringArray)
- Generate PUA bitmap icon fonts (32/64/128px) from Font Awesome via
gen_file_icons.py + compile_icons.sh toolchain
- Integrate file dispatch into file browser (double-click triggers dispatch)
- Register notepad as handler for text file extensions
- Fix init order in app.mgr (filedispatch.init before app inits)
- Refactor notepad from singleton to multi-instance (up to 8 windows)
using instance array, findStateByWid, and LVGL user_data on msgboxes
- syslogDump now outputs all five diagnostic sections (Fault Info,
CPU Registers, Process Info, System Info, Call Stack) to serial,
matching the on-screen BSOD content
- panic() detects if the crash occurred in the gfxd process and
falls back to rendering the BSOD directly to the VESA framebuffer
via driver.video text drawing, bypassing LVGL entirely
- Add DrawChar, DrawString, DrawHex, DrawInt to driver.video for
8x16 bitmap font rendering directly to the framebuffer
- Export SHOULD_CRASH flag from svc.gfxd interface so test commands
can trigger a deliberate gfxd crash
- Add app.divzero with DIV0, PF, and CRASHGFXD test commands
- Update doc/src/core/core.panic.md and doc/src/driver/video/driver.video.md
Add core.fmt.json — a complete RFC 8259 JSON library with recursive-descent
parser, serializer, builders, dot/bracket path accessors, and full cleanup.
Supports all 6 JSON value types plus JSON_ERROR for parse error reporting.
Numbers stored as Double via x87 FPU. Unicode \uXXXX escapes handled
(ASCII range emitted, non-ASCII replaced with '?').
Supporting changes:
- core.strings: add int64ToString, doubleToStr (scientific notation for
very large/small values, fixed-point for normal range, trailing zero
trimming), plus unit tests for both
- asuro.pas: wire core.fmt.json.UnitTest into the boot test suite
- mkdocs.yml: add JSON nav entry under Formats
- doc/src/core/fmt/core.fmt.json.md: full API documentation
- doc/src/core/core.strings.md: document int64ToString and doubleToStr
- doc/planning/json.md: implementation plan and design spec
- doc/planning/webgpu.md: WebGPU-over-WASM design plan (software
rasterizer backend for WASM apps importing webgpu.h)
The Drone runner environment does not have `pip` or `mkdocs` on PATH
even when installed via the Docker image. Use `pip3` explicitly and
invoke mkdocs as `python3 -m mkdocs` to ensure reliable execution.
Also add --break-system-packages to the fallback install.
Generate comprehensive documentation for all 173 source units and
integrate mkdocs-material into the build toolchain. Documentation
covers kernel core, x86 architecture, drivers, applications, and
all subsystems with a tabbed navigation structure.
- Add mkdocs.yml with material theme, mermaid support, and tabbed nav
- Add doc/index.md landing page
- Generate doc/src/ markdown for every Pascal unit in src/
- Reorganize planning docs into doc/planning/
- Add compat, lvglh, and toolchain doc sections
- Update Dockerfile to install python3 and mkdocs-material (pinned <2)
- Replace pasdoc-based compile_docs.sh with mkdocs build --strict
- Add compile_docs.sh to the main build pipeline in compile.sh
- Add deploy-docs step in .drone.yml with host volume mount to nginx
- Add site/.gitkeep for build output directory
- File picker (app.filepicker.pas): add otSYMLINK to directory case in
fp_collect_cb so symlinks like /sys appear as navigable directories
- VFS: add RemoveVirtualTree() to recursively free vdir/symlink trees
- VFS UnitTest: clean up /utest_vfs tree after all tests
- STORTEST: clean up /st_test tree after tests, fix listing leak in
cmd_stortest (GetDirectoryListingFrom result was never freed)
- Boot mount: auto-mount boot drive at /boot via mountVolume() instead
of symlink; remove /boot and /cfg from init() vdirs
- mount.asr: remove boot line (now only 'mnt {device}/sys /sys')
- Add mount.asr parser in auto_mount_volumes: reads MOUNT.ASR from boot
volume root, parses 'mnt {device}<src> <target>' lines, expands {device}
to the boot volume's /disk/volN path, creates symlinks for each entry
- Remove old asr.mnt persistent mount logic from auto_mount_volumes
- Remove persistent mount write ([p] flag) from MOUNT shell command
- Remove hardcoded /boot mount for boot volumes (now driven by mount.asr)
- Add iso/mount.asr with default /boot and /sys symlinks
- Update doc/vfs.md with mount.asr documentation
- 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
Removes per-lookup heap allocation (MD5Buffer/kfree) in favour of a
single zero-allocation FNV-1a32 pass. Drops core.enc.md5 dependency
from core.ds.hashmap.
- core.enc.fnv1a: FNV-1a 32/64-bit non-cryptographic hash with UnitTest
- core.enc.djb2: DJB2 XOR/Add 32/64-bit hash variants with UnitTest
- core.ds.bloom: probabilistic bloom filter (Bloom_New/Add/Test/Clear/Free)
using double hashing (FNV-1a32 + DJB2_32) with UnitTest
- core.ds.types: add TBloomFilter / PBloomFilter record
- asuro.pas: wire all three UnitTests into boot test suite
- ramdrive: rewrite from registerDrive callbacks to TFilesystem/TStorage_Volume
hooks (rd_Read, rd_ReadDir, rd_ReadOffset, rd_Identify) and mount via
vfs.mountVolume('/disk/ram', ...). Remove open-slot tracking; VFS now
manages file handles through the FD table.
- vfs: fix PathValid for otDRIVE nodes — split relative path into parent
directory + leaf name, list the parent via readDirCallback, and check
each entry's type so individual files are correctly identified as pvFile
instead of always returning pvDirectory or pvInvalid.
- desktop: replace static array[0..MAX_PROGRAMS-1] program registry with
a dynamic PLinkedListBase. Lazy-init on first registerProgram call.
Remove prog_count := 0 from init so programs registered before
desktop.init (e.g. notepad, diskutil) are no longer wiped.
- filedispatch, wasmrunner: add storagetypes to uses, remove stale Lock
parameter from vfs.OpenFile calls.
- progmanager: clean up duplicate uses clauses and remove invalid
kernel.bsod registration.
- compile_wasuro.sh was copying files to the /code directory which
is not where drone builds from, fixed to use $(pwd) and relative
directories based on the root.
- Add compile_wasuro.sh to sparse-clone Wasuro src/wasm from gitea
(develop branch) with caching to skip redundant pulls
- Update compile.sh to include wasuro build step in pipeline
- Update compile_sources.sh to dynamically discover -Fu paths via
find across src/ and wasuro/ directories
- Extend system.pas with FPC 3.2.2 compilerprocs required by Wasuro:
- 64-bit signed/unsigned div and mod (fpc_div_int64, fpc_mod_int64,
fpc_div_qword, fpc_mod_qword) with correct i386 parameter mapping
- 64-bit multiply (fpc_mul_int64) via three 32-bit MUL instructions
- Float-to-integer intrinsics (Trunc, Round) using x87 FPU
- Memory allocation compilerprocs (fpc_getmem, fpc_freemem)
delegating to kernel kalloc/kfree
- Exception handling stubs (reraise, raiseexception, catches, doneexception)
- setjmp/longjmp for exception address stack
- Fix sInt64 type alias (was longint/32-bit, now int64/64-bit)
- Add serial debug helpers (COM1 $3F8) for bare-metal tracing
- Wire up Wasuro in kernel.pas: init WASM VM, set I/O callback to
syslog, and run all 1103 Wasuro tests (0 failures)
- Update .gitignore to exclude wasuro/ cache directory
