Aaron 3a733b1559 feat: auto-mount boot drive to /boot; fix FAT32 deleted entry triple fault
continuous-integration/drone/push Build is passing
Details 
- 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

Aaron deb513c925 storage: fix VFS corruption, ISO9660 hang, OOM; add notepad, file picker, fdtable, GPT, async I/O 
VFS fixes:
- GetDirectoryListing(otVDIRECTORY) now returns a heap-allocated snapshot
  instead of a raw live-tree pointer; FreeDirectoryListing no longer
  corrupts the VFS tree (fixes page fault on repeated navigation)
- volumeGetDirectories: guard LL_Size > 0 before loop to prevent uint32
  underflow (0-1 = 0xFFFFFFFF) causing 4B kalloc iterations -> OOM
- Free entry^.fileName and dirList in all branches (memory leak fix)

iso9660:
- equalsIgnoreCase: guard la=0 before loop (same uint32 underflow bug)
- readDirectoryEntries/resolvePath: add 65536/256-iter safety caps

storagemanager:
- Strip debug syslog calls that were allocating 6+ strings per I/O
  (hundreds of I/Os x 6 allocs exhausted the heap)

Process manager:
- Per-process FDTable and Cwd initialised on create, freed on reap
- proc_await: use pointer-indirection spin per lesson #6 (FPC caches
  non-volatile reads; raw while flag=0 returns immediately)
- graphicsrefresh: move LVGL handler from timer ISR (IF=0) to a
  dedicated process so LVGL callbacks can call blocking I/O

New units:
- fdtable.pas: per-process file descriptor table (fd_alloc/get/close)
- iorequest.pas: heap allocation helpers for TIORequest
- gpt.pas: GPT header/entry read + CRC validation
- filepicker.pas: reusable OS-level open/save file picker dialog
- notepad.pas: GUI text editor with selection, indent, save-as

Shell commands (diskcmd, partcmd, volcmd, diskutil):
- Route output to stdout_buf instead of syslog (lesson #4)
- diskutil: async add/remove/format partition; cache-based device display

Add Apache 2.0 license headers to storagemanager.pas, iso9660.pas,
fat32.pas, storagetest.pas

Lessons learnt: #9 VFS listing must return snapshot (not live pointer)

t3hn3rd de6fde05cc feature: preemptive process management - implementation progress 
Implement a preemptive multitasking system for the Asuro kernel.

Context Switching & Scheduling:
- Custom IRQ0 ISR (contextswitcher.pas) with PUSHAD/POPAD ESP-swap
- Round-robin scheduler with priority-based quantum
- Process table using DList of PProcessContext pointers
- Idle process (PID 0) replaces kernel HLT loop

Process Lifecycle:
- create/kill/terminate/sendMessage API (processmanager.pas)
- Process states: Created, Running, Ready, Suspended, Awaiting,
  Finished, Error
- Parent-child tracking (ParentID, smChildExited notification on reap)
- proc_yield, proc_sleep_ms, proc_await, proc_suspend, proc_exit

Resource Binding & Cleanup:
- Per-process resource list
  (bindResource/unbindResource/unbindAllResources)
- TCP sockets auto-bound to owning process (OwnerPID on TTCPSocket)
- socket_cleanup + auto-unbind in DestroySocket

VTerminal Refactor:
- Multi-instance design (heap-allocated TVTermState per terminal)
- Foreground process with incremental stdout/stderr drain via LVGL timer
- Ctrl+C kills foreground process (killForeground)
- Per-terminal CWD, dir stack, FS builtins (CD/LS/PUSHD/POPD)
- Background job support (& suffix, JOBS/FG commands)
- Command history (Up/Down arrow)

Command Consolidation:
- 14 commands extracted from 9 units into centralized progmanager.pas
- Command procedures exported in host unit interfaces
- E1000/TRACER/stdio builtins kept in-place (conditional/circular)

New Units:
- src/include/proctypes.pas — process type definitions
- src/processmanager.pas — core process manager
- src/prog/ping.pas — standalone ICMP ping process
- src/prog/testcmd.pas — test command (proc_sleep_ms demo)
- src/testprocs.pas — process subsystem smoke tests

Misc:
- ICMP callbacks gain userData parameter for concurrency-safe ping
- CLI/STI guards on kalloc/kfree (lmemorymanager.pas)
- LV_KEY_CTRLC constant + Ctrl+C interception in LVGL keyboard hook
- Window owner PID tracking (windows.pas)
- ISR_32 gate override support (isrmanager.pas)

t3hn3rd 7bbcc44c5e Feature: USB - Hotplug, mass storage, disconnect callbacks, dynamic device lists 
- Add disconnect callback (fnDisconnect) to TUSBDevice for safe unplug handling
- Add HotplugArmed/PortChangePending flags to TUSBHCDriver for deferred
  hotplug processing from ISR context (OHCI RHSC, EHCI PCD, xHCI PSC)
- Implement usb_rescan_port() and usb_check_hotplug() in usbcore
- Add usb_bulk_transfer_wait() with timer-based timeout (bios_data_area)
- Add timer-based timeout to usb_control_msg polling loop
- Replace static device arrays with dynamic linked lists in class drivers:
  usb_keyboard (KeyboardList), usb_mouse (MouseList), usb_storage (StorageList)
- Add 3-strike fail-count self-deactivation in keyboard/mouse poll loops
- Add unload() disconnect handlers for keyboard, mouse, and storage drivers
- Implement USB Mass Storage BOT driver (usb_storage.pas):
  CBW/CSW transport, SCSI INQUIRY/READ_CAPACITY/READ10/WRITE10,
  storagemanagement integration with read/write callbacks
- xHCI: acknowledge port status change W1C bits in event handler
- Integrate usb_check_hotplug + poll_keyboards/poll_mice into kernel main loop

t3hn3rd f752be48ce refactor/feature/fix: Major refactor of codebase
continuous-integration/drone/push Build is passing
Details
continuous-integration/drone/pr Build is passing
Details 
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.
