- Remove FAT_WRITE_PREALLOC_BYTES (redundant at typical cluster sizes)
- Simplify fatPreallocClusterCount to always return MAX_CLUSTERS
- FAT32CloseFile: truncate pre-allocated tail clusters back to ByteSize
on close, freeing FAT chain entries beyond the file's real size
- Add TFATWriteRef + WriteRefs[32] in TFATVolumeCtx and Registered flag
on TFATOpenFile to track concurrent write handles per dir entry
- fatRegisterWriteHandle / fatUnregisterWriteHandle: CLI-guarded slot scan
keyed by (DirLoc.SectorLBA, DirLoc.EntryIdx)
- Register on first FAT chain extension in FAT32EnsureCapacityForWrite
- Truncation in FAT32CloseFile skipped unless this is the last writer
(prevents RunMap corruption in concurrent-open scenarios)
- Add forward decl for fatFreeClusterChain to fix ordering issue
- app.iotest: update default path to /disk/vol2/IOTEST.BIN
- Add TStorageLifecycleWatch with watch_lifecycle/unwatch_lifecycle API (up to 32 watchers)
- Add notify_lifecycle to broadcast mount/unmount/format events to registered callbacks
- Replace raw puint32 config in format_volume with typed PFSFormatParams
- Add volume_is_busy, volume_is_formatting, volume_set_mounted helpers
- Add lifecycleFlags field to TStorage_Volume for tracking busy/formatting state
- Expand app.diskutil with improved commands and volume state reporting
- Minor improvements to core.util, arch.x86.util, proc.mgr, VFS, and flatfs
- Remove obsolete driver.storage.fs.fat32.old.pas
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 '.')
- 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
- 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
- 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.
- Decode multiboot boot_device byte in storagemanager to identify boot device
- Add isBootDevice to TStorage_Device; propagate isBootDrive to volumes
- Create /boot VFS directory at init; mount boot volume there in auto_mount_volumes
- Fix getDirEntries skipping \-marked (deleted) FAT32 entries to prevent
triple fault when navigating into a deleted directory via file picker
refactor(stdio): replace console/terminal command system with buffer-based stdio
- Introduced stdio.pas as the unified command I/O layer.
- All 31 command procedures across 15 files now receive stdin_buf,
stdout_buf, and stderr_buf (POutBuf) instead of a single outbuf.
- vterminal.pas creates all three buffers per command invocation and
displays both stdout and stderr.
- Deleted console.pas, terminal.pas, and 9 obsolete windowing programs
(shell, splash, edit, memview, themer, netlog, vmlog, vmstate, udpcat).
- Migrated all registerCommand calls to stdio, rewrote vterminal
processCommand to use stdio.findCommand, and added proper error
routing to stderr for invalid params, bad paths, and system errors.
refactor(syslog): replace console logging with serial-backed syslog
- Introduced syslog.pas for kernel-level logging over serial/dev.
- Migrated all boot logging in kernel.pas from console.outputln/
writestringln to syslog.logln/writestringln.
- Converted 19 fault handlers, hashmap, lists, scheduler, tracer, net,
udp, and all driver init paths to use syslog.
- Rewrote BSOD in util.pas (50+ calls) from console to syslog.
- Removed CONSOLE_SLOW_REDRAW, TRGB565, TRGB565Pair, and HWND
from system.pas.
fix(keyboard): add ring buffer and proper press/release cycling for LVGL input
- Replaced the single last_key/key_pressed slot in lvgl.pas with a
16-entry ring buffer (kb_buf, kb_head, kb_tail) to prevent ISR
overwrites when typing fast.
- Added a kb_pending_release flag so each keystroke gets a
full PRESSED->RELEASED cycle before the next key is consumed —
LVGL requires this pairing and was silently dropping intermediate
keys when receiving consecutive PRESSED events without
intervening releases.
feat(vterminal): use Hack monospace font for terminal output
- Added Hack Regular 14px (hack_14.c) as a custom LVGL font.
- Removed the .static_bitmap field from the generated font file
(not present in LVGL 9.2 lv_font_t struct).
- Declared the hack_14 external symbol in lvgl.pas and switched
vterminal's text label from lv_font_montserrat_14 to hack_14
for proper monospace terminal rendering.
Added the apache license to all source files, accounting for authors. Also added a license.md containing the apache license + contributors.md listing all contributors.
