t3hn3rd 1ae867d929 fix: adapt subsystems to new VFS volume API and fix desktop program registry
continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
- 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.

t3hn3rd 2bfbb44cfb feature: WASM execution pipeline, file dispatch, RAM drive, and VFS handle table
- Add file-type dispatch registry (filedispatch.pas) matching files by
  magic header bytes and routing to registered handlers
- Add WASM integration layer: wasmshim, wasmio, wasmrunner, wasmcleanup
  providing full WASI Preview1 bridging (fd_write/read, proc_exit,
  clock, random, args passthrough, environ stubs)
- Add RAM drive (ramdrive.pas) providing in-memory VFS at /disk/ram
  with a built-in hello world WASM binary
- (Placeholder) Implement VFS handle table for proper
  open/read/write/close/filesize routing through registered drives
  and devices
- Integrate file dispatch into vterminal for unknown commands, supporting
  both foreground and background execution of dispatched files
- Expand progmanager init with PS, KILL, TERMINATE, DEV, DISK, MEMRAW,
  BSOD, IFCONFIG, ARP, and TCP commands; wire up ramdrive, filedispatch,
  and wasmrunner initialization
- Replace serial.sendString with syslog.logln in desktop launcher

t3hn3rd b51881ced7 feat: integrate Wasuro WASM runtime into Asuro build chain
- 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

t3hn3rd 0d6f1e006c 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 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.

- desktop: Resolution/Graphics fields now read from video frontbuffer

  the initial VBE boot driver is reported before any setMode call

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.

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)

continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
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.

t3hn3rd fb675a2299 feature: implement TCP (RFC 793) protocol driver
Add full TCP/IP stack implementation at L4 alongside UDP and ICMP.

Core Protocol Engine:
- TCP types in nettypes.pas (header, TCB, state enum, error codes,
  callbacks, OOO entry, socket structures)
- 3-way handshake (active & passive OPEN)
- Reliable data transfer with ACK and sequence number tracking
- Graceful close (FIN_WAIT, CLOSE_WAIT, LAST_ACK, TIME_WAIT)
- RST send/receive handling
- Retransmission with exponential backoff (max 5 attempts)
- Pseudo-header based checksum (RFC 793)

Server Support:
- LISTEN → SYN_RECEIVED → ESTABLISHED passive open path
- Listen backlog enforcement (configurable per-socket)
- accept() to retrieve established child connections

Robustness & Hardening:
- Delayed ACK timer (~200ms)
- Nagle's algorithm (buffer small sends while unACKed data pending)
- Jacobson/Karels RTT estimation with adaptive RTO
- Congestion control (slow start / congestion avoidance)
- Zero-window probing with exponential backoff
- MSS option negotiation in SYN/SYN-ACK (Kind=2, Len=4)
- Keep-alive (30s idle, 10s interval, 5 probes)
- Out-of-order segment reassembly (4-slot buffer)

Terminal & Testing:
- tcpconnect: active open + send "Hello, World!"

t3hn3rd f427b7bcc7 refactor(memory): complete PMM/VMM/LMM rewrite - bitmap allocators, bug fixes, hardening
continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
PMM Rewrite:
- Replace ~8KB record array with compact bitmaps
  (PhysPresent/PhysAlloc/PhysScanned, 128B each)
- Add PhysOwner[0..1023] for per-block ownership tracking
- new_block: O(1) amortised via NextFreeHint + dword-level BSF scan,
  returns 0 as OOM sentinel
- free_block: O(1) direct bit clear with double-free detection
- alloc_block: validates PhysPresent and PhysAlloc bits before allocation
- Add pmm_free_blocks/pmm_total_blocks stats functions

VMM Correctness Fixes:
- Fix free_page block extraction (Address SHR 10, was using
  raw Address field)
- Fix invlpg operand (use virtual address, was passing PDE index)
- Clear PDE entry on free_page before returning block to PMM
- Remove map_page double-write (delegate to map_page_ex only)
- Add OOM propagation (new_page returns false if PMM returns 0)
- Fix missing pop_trace in new_page error path

LMM Rewrite:
- Replace per-entry record array with bitmap allocator
  (93% vs 43% page efficiency)
- Layout: Header(24B) + Bitmap(64512B) + Padding + Data at 0x10000
- SIZE_PREFIX=16 for 16-byte aligned returns (SSE MOVAPS requirement)
- Next-fit bitmap scan with roving hint (NextFree) and dword-level
  fast skip
- Large alloc sentinel (LARGE_ALLOC_MAGIC=$FFFFFFFE) so kfree detects
  klalloc'd memory
- Implement klfree (was previously a no-op - pages could never
  be returned)
- Implement try_release_page (return fully-free heap pages to VMM/PMM)
- Fix interrupt safety: stack-balanced pushfd/cli/pop +
  restore_if (sti only)
  Fixes Bad TSS caused by popfd restoring dangerous EFLAGS bits (NT, IOPL)
- Zero memory via rep stosd instead of byte-by-byte loop

Hardening:
- kalloc OOM now triggers BSOD instead of returning nil
  (90% of callers don't check)
- Double-free detection in kfree (verify bitmap bits set before clearing)
- Guard bytes ({$IFDEF DEBUG_LMM}): $DEADBEEF sentinel for buffer overrun detection
- kpalloc: bounds check (block >= 1024 -> GPF) + syslog MMIO mapping audit log

Observability:
- Add MEMINFO command as src/prog/meminfo.pas (moved from inline kernel.pas)
- Displays multiboot memory, PMM block stats, LMM heap stats
- Register via progmanager.pas following standard prog pattern

Files changed:
- src/pmemorymanager.pas
- src/vmemorymanager.pas
- src/lmemorymanager.pas
- src/kernel.pas

t3hn3rd 8169d93a9c refactor: move render loop & USB hotplug to timer-driven units
continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
Replace the blocking main render loop in kernel.pas with two new
timer-hooked units that are driven by the 1024Hz PIT interrupt:

- graphicsrefresh: calls desktop.update, uidebug.update, lvgl_handler
  and video.Flush every 4 ticks (~256 FPS target).
- usbhotplug: calls usbcore.usb_check_hotplug every 1024 ticks (~1Hz).

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.

Also removes the unused myUserLandFunction and reorders early syslog
init calls for clarity.

t3hn3rd c237553508 fix: ps2_keyboard report key-up events for break codes
The PS/2 keyboard callback hardcoded is_down_code := true for every
scancode, so key releases were never reported. This caused keys to
repeat endlessly until the next key was pressed.

In PS/2 scancode set 1, bit 7 indicates a break (release) code.
The callback now:
- Detects break codes via (scancode AND $80)
- Masks to base code (scancode AND $7F) for key matrix lookup
- Sets is_down_code := false for break codes
- Updates modifier state (shift/ctrl/alt) before building the
  key event, so modifier releases take effect immediately

t3hn3rd 0c96d32754 feature: move all USB HC drivers from polling to interrupt-driven completion
Replace main-loop polling (poll_all, poll_keyboards, poll_mice) with
hardware interrupt handlers for all four USB host controller drivers.

Each HC driver (XHCI, EHCI, OHCI, UHCI) now:
- Registers an ISR on its PCI interrupt line via isrmanager
- Enables hardware interrupts after HC initialization
- Acknowledges interrupt status in the ISR before calling poll,
  preventing interrupt storms on level-triggered PCI lines
- Uses a PollBusy re-entrancy guard to prevent ISR/inline poll races

usbcore gains a completion hook system (register_completion_hook /
fire_completion_hooks) so HID drivers (keyboard, mouse) are notified
directly from the ISR after transfer completion.

Files changed:
- usbcore.pas: completion hook infrastructure
- XHCI.pas: ISR, enable_interrupts, submit ordering fix
- EHCI.pas: ISR, enable_interrupts, status ack in ISR
- OHCI.pas: ISR, enable_interrupts, status ack in ISR

t3hn3rd beb4b253ab fix: guard against uint32 underflow in memset/memcpy and strings unit
When size=0 was passed to memset() or memcpy(), the loop bound
`0 to size-1` underflowed to $FFFFFFFF, iterating ~4 billion times
and causing an immediate page fault.

Added `if size = 0 then exit` guards to both memset() and memcpy()
in util.pas.

Also guarded all `for i:=0 to X-1` loops in strings.pas where X
could be 0 on empty string inputs:
- stringToUpper: wrap loop in `if stringSize > 0`
- stringToLower: wrap loop in `if stringSize > 0`
- stringEquals: early exit when both sizes are 0
- stringToInt: early exit when string is empty

Additionally fixed all previously identified bugs in strings.pas:
- hexStringToInt: guard against empty string underflow
- stringConcat: cache stringSize calls to avoid redundant O(n) scans
- stringTrim: clamp length to source string size
- stringSub: bounds check start/size against source length
- stringReplace: complete rewrite - was using stringEquals() for
  substring matching (only matched at string end), dropped prefix
  chars, had dangling assignment overwriting valid result with
  uninitialized pointer, and had unused variable
- stringIndexOf: rewritten to use new stringMatchAt() helper for
  correct substring matching
- stringContains: simplified to delegate to fixed stringIndexOf(),
  also fixing uint32 underflow when sub was empty
- stringToInt: removed always-true `v >= 0` check on uint32
- intToString: implemented (was a stub returning ' ')
- Added stringMatchAt() helper for prefix comparison
- Added comprehensive UnitTest procedure with 77 assertions
  including adversarial empty/nil/boundary inputs

continuous-integration/drone/push Build is passing
continuous-integration/drone/pr Build is passing
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.

otherwise the CPU raises #UD (invalid opcode). Hyper-V enforces this
strictly; VirtualBox was silently tolerating it.

- Check both AVX and XSAVE CPUID flags before attempting AVX enable
- Set CR4.OSXSAVE (bit 18) before issuing XGETBV/XSETBV
- If XSAVE is not exposed by the hypervisor, AVX enable is skipped
  gracefully instead of faulting

t3hn3rd fcfe7c3204 fix: Mouse driver Hyper-V compatibility + resolution-independent bounds clamping
- Add mouse_wait_long() with 100,000 iteration timeout for init-time
  i8042 controller commands (mouse_write/mouse_read/load). The original
  mouse_wait() stays at 100 iterations for ISR-safe use in main().

- In load(): use mouse_wait_long() for all direct port I/O ($64/$60)
  and clear CCB bit 5 (AND NOT $20) to ensure the mouse clock is not
  disabled — required for Hyper-V which enforces this strictly.

- Replace Console.getConsoleProperties^.Width/Height with
  video.frontBufferWidth/Height for mouse bounds clamping. The old
  console properties are zero when console.init() is not called,
  which locked the cursor to (0,0). Add 'video' to uses clause.

- lvgl.pas: Make lvgl_flush_cb BPP-aware; add ARGB8888->RGB565
  conversion path for 16bpp, keep direct copy for 32bpp. Replace
  static lv_buf1 array (hardcoded 1600px wide) with kalloc'd buffer
  sized to actual screen width.
- doublebuffer.pas: Fix allocateBackBuffer size from (W*H*BPP) to
  (W*H*BPP) div 8 to get correct byte count.
- vesa.pas: Account for BPP in allocateVESAFrameBuffer page range
  calculation to avoid under-mapping at higher BPP/resolutions.
- Removed the initialization of console in kernel.pas as this will

t3hn3rd 3ae349fbc8 New modular driver set for video
Started outlining how the modular driver set will look for video drawing routines. Currently supports Drawing pixels to the screen & Flushing backbuffer -> frontbuffer.
Still very much test code, tracer is used everywhere for debugging, NOT DEVELOP READY.
Many more draw routines need implementing - such as, but not limited to; drawRect, drawBitmap, drawLine, drawCurve, drawCircle.

TODO: Implement the aforementioned routines in all VESA modes + WindowManager.
2022-02-07 19:48:00 +00:00
t3hn3rd 78c060c114 Abstracted video driver somewhat
Split out video driver into abstract/standard/implementation.
2022-02-07 19:48:00 +00:00
t3hn3rd cd925e96c2 Enabled AVX + Changed flush to flush 2 pixels per iteration. 2022-02-07 19:48:00 +00:00
t3hn3rd 142dd486dd Double buffering implemented
Double buffering is now enabled with the use of the new large alloc (klalloc).
2022-02-07 19:48:00 +00:00
t3hn3rd beeeabd441 Expaneded Video.pas and addec color.pas
Backbuffer will need modification to lmemorymanager to remove the limits to allocation size.

#Flat filesystem
A super simple filesystem for asuro. Folders are emulated in filenames.
Starts with disk info sector, sector 0 of volume
---
#### disk info
jmp2boot : ubit24;
OEMName : array[0..7] of char;
version : uint16 // numerical version of filesystem
sectorCount : uint16;
fileCount : uint16
signature : uint32 = 0x0B00B1E5
the Rest of the sector is reserved
---
Starting from sector 1 is the file table. Table size is determined by entry size (64) * fileCount
---
####File entry
name : array[0..59] of char //file name max 60 chars
fileStart : 16bit // start sector of data
fileSize : 16bit // data size in sectors
