- Don't hardcode constant string lengths.
- Use `_strnicmp()` -- Ideally we shouldn't have to unconditionally upcase
the global kernel command-line string to perform substrings comparisons.
- Cast `atol()` returned value to `ULONG`.
- The "IRQ" debugger option was introduced in commit 5a6adb4f13 (r2546).
It was used by the in-kernel GDB stub, to manually wire an interrupt
handler `GspBreakIn()` to allow the debugger to break into the system
when a command is received on the GDB serial port.
Side-remark:
The hooking was done via `HalGetInterruptVector()` + `IoConnectInterrupt()`,
but only at phase 1 initialization when the memory manager was up, which
can be "late" enough during system boot initialization.
Instead of using `IoConnectInterrupt()`, one could have used explicit
`KeInitializeInterrupt()` + `KeConnectInterrupt()` calls that would
have worked much earlier in the boot stage.
- This functionality was soon after disabled in commit c804ca06be (r2946)
in the GDB stub (see `ntoskrnl/kd/gdbstub.c!KdGdbStubInit()`), never
to be re-enabled again.
It was removed completely in commit e160c0fb26 (r14799).
- Since ReactOS was (until recently) always debugged locally using the
in-kernel KDBG debugger, break-in was done with TAB-K keypress,
intercepted by the keyboard driver that triggered a `DbgBreakPoint()`,
thus no break-in via serial port interrupt was necessary.
- Remote debugger break-in detection, which is the standard method that
is used when remote-debugging using KD transport DLLs and WinDbg, was
introduced in commit 12e7593f24 (r25984). As with the rest of debugger
communication and as done on Windows, detection is done by polling the
serial port at certain times, namely in the `KeUpdateSystemTime()`
kernel procedure periodically invoked by the timer interrupt.
This break-in detection was then erroneously removed in commit bf8b9467dc
(r45140), and reinstated in commit 014b23b9a (r56194).
- Parsing of this "IRQ" option was copy-pasted in other modules (FreeLoader,
KDCOM, and KDGDB), even though it was never used. The parsing was then
removed in KDBG itself in commit 95faf65ebf, but left in the other
modules... until now!
Cherry-picking commit
https://github.com/bobranten/Ext4Fsd/commit/3158b917a20019d2fdc3fb84b9ac4ac03af7b862
See https://github.com/bobranten/Ext4Fsd/issues/83 for more information,
and debug traces.
## How to reproduce:
- Format a partition in Ext2 with Paragon Hard Disk Manager 2010 Professional.
- Compile ReactOS with MSVC, ensuring that the driver is compiled with
`EXT2_HTREE_INDEX` defined and set to 1, and with Run-time error checks
enabled with the `/RTC1` flag (this is the default in our source tree).
- Install ReactOS on this partition.
## What's being observed:
After reboot, some filesystem paths are accessed, and the code inside the
`#ifdef EXT2_HTREE_INDEX` block is taken (in ext2/src/dirctl.c#L777-L794).
For some reasons, the retrieved `rc` doesn't get the "expected" value and
the `goto errorout;` path is taken. After this label, `FileIndex` was
reset to `ByteOffset`, which remained uninitialized.
A bugcheck ensues because of the failed check (usage of uninitialized variable).

RtlConvertUlongToLargeInteger and RtlConvertLongToLargeInteger are
obsolete NT routines that assign a 32-bit integer to LARGE_INTEGER.QuadPart.
Replace all driver/DLL usages with inline .QuadPart assignments or
standard C/C++ casts. This removes unnecessary function calls.

Use hardcoded value '1' instead of predefined 'PCI_BUS_INTERFACE_STANDARD_VERSION', as in the current upstream.
Import upstream commit https://github.com/coolstar/sklhdaudbus/commit/4c92e71ef9e91360cb35be6a09aadb2c3eaaca27.
According to the note from CoolStar, that defined value is different on Windows 11, so it causes some problems and '1' should be used instead.
Missed that during the import before.
Addendum to 7c2d923007.
Its purpose is to offer an out-of-the-box generic framebuffer video
(a video miniport driver for win32k will be introduced in a future PR)
to ease ReactOS porting to other possibly non-PC-compatible systems,
where no VGA-compatible video is present and only linear framebuffers
are available; for example: XBOX, UEFI with GOP only, AppleTV, etc.
Of course, once ReactOS is ported, one can then (and should) write,
or use existing video drivers tailored to the system of interest.
Together with our FreeLoader, this driver could also be employed for
of porting/modding Windows 2000/XP/2003 attempts to other platforms,
as this has been done by external contributors.
Current limitations:
- Only supports 32 bits-per-pixel ARGB format. This limitation will be
removed in subsequent PR(s).
- May be slow during rendering (region color filling and scrolling);
I will try to improve this as time goes.
This driver's code is loosely based upon preliminary code by Justin Miller
and on the existing XBOX bootvid implementation.
Tested by Justin Miller (@TheDarkFire) for UEFI, and by Sylas Hollander
(@DistroHopper39B) with his AppleTV port.
It has also been tested with VESA linear modes on PC by myself.
Stop pointless target_sources(xxx PRIVATE $<TARGET_OBJECTS:gcc_ssp_nt>). The only effect it has is to force the object file into the target, which was already done by specifying the libraries as OBJECT libraries, which is also pointless, and only leads to problems.
Use `PCSTR` for the type of the (Hal,Inbv,Vid)DisplayString() routines'
`String` parameter, instead of `PCHAR` or `PUCHAR`, since it points to a
NUL-terminated string. (The buffer isn't a counted string.)
And improve SAL annotations along the way.
This makes the code more readable than using e.g. `VidpScrollRegion[0]`,
`VidpScrollRegion[1]` etc. instead of `VidpScrollRegion.Left`,
`VidpScrollRegion.Top` respectively.
Based on a suggestion by Dmitry Borisov.
In addition:
- move back common function prototypes to precomp.h;
- const-ify `VidpFontData` and adjust its usages;
- improve SAL annotations for `InitPaletteWithTable()`;
- rename the (Vid)ResetDisplay() parameter to "SetMode".
These drivers expect PC/AT compatible hardware thus they are unsuitable for PC-98.
Disable the drivers for the time being until we have a proper implementation.

Addendum to fa1ec0a2ed. CORE-16216 CORE-16219
This patch adds the NETIO.SYS driver to ReactOS. NETIO.SYS
is part of Windows since NT6 (Vista).
The driver is not feature complete (meaning some functionality is
unimplemented) but does its job quite good for what it originally
was written for (which is getting WinDRBD working on
ReactOS/Windows Server 2003 SP2).
The driver re-uses parts of the AFD.SYS driver, namely those
functions that ease communitating with the transport device
interface (TDI). Other than that, following features are implemented
and should work:
* TCP/IP networking: connect, listen, accept, read, write
* UDP/IP networking: write
So in a nutshell TCP/IP support is completed, UDP support is
partially complete and ICMP support does not exist yet.
In particular the listen/accept mechanism allows one to write
kernel side TCP servers that one can connect to via the internet.
The netio driver is licensed under the MIT license, see the file
netio.c for more details.
Have fun with it :)

We want to use the TDI helper functions also in the NETIO.SYS
driver which comes with the next commit. The code was modernized
a bit (usage of DPRINT, doxygen style comments) but other than
that it was left unchanged.
