commit d8f7df2599dc3e147ae585855f396d74e8a28ef4
Author: QuzarDC <qu...@co...>
Date:   Sun Sep 21 19:50:18 2025 -0400

    fs_dcload: Drop dir list.
    
    The dir list was a means to track which handles were
    dirs or not. Instead use the `path` member of the object
    to do the same and return an opaque token to that object
    rather than the `hnd` used by the host-side.

commit 183f3caa980500ee5ef4386920befd0ba2077fb9
Author: QuzarDC <qu...@co...>
Date:   Sun Sep 21 18:41:10 2025 -0400

    fs_dcload: Set errno on not finding a file.
    
    `ENOENT` to match the `ENOTDIR` set by the dir path.

commit 57eac6bf98c1b549df19e81efd433161f846f24c
Author: QuzarDC <qu...@co...>
Date:   Wed Jun 25 04:11:50 2025 -0400

    Update filebrowser example to show file stats.
    
    Simple addition to draw the Filesize and modification
    time as provided by stat. Was updated in order to help
    validate functionality of stat over `/pc/` after updating
    to use a standardized stat rather than custom dcload one.

commit b8ca37df81ce110ef6156c118fc04d9a0b236b6e
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 20:18:55 2025 -0400

    fs_dcload: Protect against possible buffer overflow in readdir.

commit be56dc0eef09b433f6bb50f260c482c865b6c382
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 17:17:12 2025 -0400

    dcload: Replace dcload_dirent with our standard one.
    
    The sizes and defined types match. The risk in doing this
    is only in if the host side needs to change its data types.
    In that case though, there would have to be changes on the KOS
    side as well.

commit dc2f7b2e5524557dbb03f676d296c680edc31bb1
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 15:52:46 2025 -0400

    dcload: Implement each unimplemented dcload command.
    
    chdir, chmod, fstat, time, utime, and exit had never been
    implemented in KOS. utime has been left as a commented out
    stub to note how there would likely need to be updates to
    the tool in order for it to work.

commit 8a0b8d10df3819988dfb1495a2cb1ea3af7e6bc3
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 03:58:05 2025 -0400

    dcload: Whitespace and junk cleanup.
    
    Mostly moving stars, but also some lining up of comments and
    removal of a prototype that had no function.

commit 43b0ab08ef9cd8b51a060d2cec0c5598394d05c6
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 02:11:44 2025 -0400

    dcload: Add assignwrkmem function.

commit 5eaa446f8e63def5a245b011d2418e306f1e36af
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 03:50:02 2025 -0400

    dcload: Add dir related functions.
    
    Open, close, read, and rewind. Additionally move the dirent
    type over.

commit 4d71ba186d4a9ca2a7fa5f375841dcdb6578ccc9
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 03:28:47 2025 -0400

    dcload: Create function for stat.
    
    Bigger than others as the bespoke stat type was moved.

commit 583490490f4c194821c95aec365d1a65635be9ac
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 03:19:16 2025 -0400

    dcload: Create functions for link, unlink, and lseek.

commit 1cf3ca4c592700e1799a057a1d9076caa646e3fd
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 03:04:36 2025 -0400

    dcload: Create functions for read, write, open, and close commands.

commit 946586d1ad3349e1381dde236990d1bae986cb3e
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 02:53:30 2025 -0400

    dcload: Create function for `gethostinfo` command.

commit 530af522581825b4ae9152e68357bb5a168079eb
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 02:43:34 2025 -0400

    dcload: Move gdb packet function to new file.

commit ab38ca87b30f641d50fdf5b35ad357b370b1c469
Author: QuzarDC <qu...@co...>
Date:   Tue Jun 24 02:04:31 2025 -0400

    dcload: Rename internal vfs functions.
    
    To follow our standard naming convention as well as
    `dcloadgetgdbpacket` a lot of the syscall functions
    for the file ops would overlap with these names. So
    renaming in order to get the conflict out of the way.

commit 4837c4b9b8a3481ba5f02c6f66b904e629007fa2
Author: QuzarDC <qu...@co...>
Date:   Mon Jun 23 20:33:07 2025 -0400

    fs_dcload: Reduce scope and severity of locking.
    
    Currently `fs_dcload` uses fairly broad spinlocks over most of
    each function. From the history it looks as though these are
    spinlocks simply because we didn't have other sorts of locks
    when this was originally written. It can't have to do with the
    actual operations as the syscall has always been called with
    irqs disabled.
    
    So here I make three changes:
    
    First:  Implement a rwsem to protect the shared dir list. This is
    	specifically for protecting access to that data structure.
    
    Second: Reduce the scope of the 'mutex' locks. Leave them only in
    	cases where multiple dcload commands must be issued and
    	we should expect that others wouldn't be issued between them.
    	It may be that these can be shrunken down slightly more.
    
    Third: Change the spinlocks to mutexes.

commit b62400ea86be0266c095fa80a72aefe1caa06f2d
Author: QuzarDC <qu...@co...>
Date:   Mon Jun 23 15:06:27 2025 -0400

    dcload: Change last remaining arch/types to stdint

commit 4daa9835b384abe87fbeef274a5e434e43d5207a
Author: QuzarDC <qu...@co...>
Date:   Sun Jun 22 23:36:56 2025 -0400

    dcload: Migrate syscall into our BIOS syscalls file.
    
    Create a proper C function for dcload's syscall to match
    the way we do for other syscalls rather than as a macro wrapper
    around an asm file.
    
    Additionally move the definitions of the commands for the syscall
    to accompany it. I had considered whether this might be better as
    its own `syscalls-custom` since it does operate differently, including
    having a function to detect whether it's present or not. It may be that
    this could represent a defining pattern for the use of other custom
    syscalls from modded BIOS or alternative loaders (dcload NG/3).

commit 826789b2574552848bdd0b1b4160f96da2947805
Author: QuzarDC <qu...@co...>
Date:   Sun May 11 01:50:52 2025 -0400

    Rename and expose if the dcload syscall is installed.
    
    Removed two usages that were redundant. There is no
    condition where `dcload_type` could be set to `TYPE_SER`
    while dcload is not detected.
    
    Renamed to indicate that it's not a part of the dcload vfs.
