Addendum to 5f2ca473. CORE-16216 CORE-16219
According to PC-9801 Bible p. 50, divisor for PIT will become unsupported in some cases after having removed the fractional part. Replace 19200 value with 9600 which is supported by both 10 MHz and 8 MHz machines.
Our legacy KD module is slowly being phased out for the more recent KD64
Kernel Debugger that supports WinDbg, but at the same time we must retain
support for GCC debugging and the KDBG interface.
For the time being few #ifdef _WINKD_ have been introduced in KD64 so that
some of its code/data does not completely get shared yet with the legacy KD,
until the latter becomes phased out.
KD Modifications:
=================
- Remove the implementation of NtQueryDebugFilterState() /
NtSetDebugFilterState() that now comes entirely from KD64.
- Remove KD variables that are now shared with KD64.
- Share common code with KD64: KdpMoveMemory(), KdpZeroMemory(),
KdpCopyMemoryChunks(), KdpPrint(), KdpPrompt().
- KDBG: Remove the duplicated KdpCopyMemoryChunks() function.
- In KdpServiceDispatcher() and KdpEnterDebuggerException(), call the
KdpPrint() worker function that correctly probes and captures its arguments.
- Temporarily stub out KdEnterDebugger() and KdExitDebugger() that is used
by the shared code, until KD is removed and only the KD64 version of these
functions remain.
- Re-implement the KD/KDBG KdpPrompt() function using a custom KdpPromptString()
helper compatible with KD64, that is called by the KD64 implementation of
KdpPrompt(). This KdpPromptString() helper now issues the prompt on all
the KD loggers: e.g. if you use both at the same time COM-port and SCREEN
debugging, the prompt will appear on both. Before that the prompt was always
being displayed on COM port even if e.g. a SCREEN-only debug session was used...
- ppc_irq.c: Fix the prototype of KdpServiceDispatcher().
KD64 Fixes:
===========
- Initialize the MaximumLength member of the counted STRING variables
before using them elsewhere.
- Get rid of alloca() within SEH block in KdpPrint() (addendum to 7b95fcf9).
- Add the ROS-specific handy dump commands in KdSystemDebugControl().
- Introduce KdpScreenAcquire() / KdpScreenRelease() helpers that allow
to correctly acquire or release the screen when using INBV for
"Screen-Mode" debugging.
- Introduce KdpAcquireLock() / KdpReleaseLock() helpers so as to reduce
the copy-pasted code required when acquiring spin-locks in the KD debug
logger functions.
- Close the opened KdpLogFileHandle file in the KdpInitDebugLog() logger
in case we failed to create the logger writer thread.
Also use explicit kernel-mode handle when opening the log file.
- static-ify some local variables, remove few hardcoded values, and
minor formatting.
- Correctly define the INIT_FUNCTION's.
- Import KdpCopyMemoryChunks() from kd64/kdapi.c, and re-implement
KdbpSafeReadMemory() and KdbpSafeWriteMemory() around it.
Note that these functions read virtual memory and are equivalent of
the kd64 KdpReadVirtualMemory() and KdpWriteVirtualMemory()
respectively.
- Get rid of the KdpEnableSafeMem() call in KdInitSystem().
- Adjust kd gdbstub.c wrapper in accordance.
- Always include kd64.h
- Change KdpPrompt() prototype to be compatible between KDBG and _WINDK_
- Rename KdComponentTable to KdpComponentTable to prevent a conflict
- Add some functions stubs and global variables
I still don't like that we're copying code between KD and KD64 instead of sharing it.
But as both modules are totally distinct at the moment, I won't be the one introducing shared functions between them.
This is a follow up to 50ae5e7c52, which TortoiseGit accidentally turned into a "Message only" commit...
Never hit ALT+Y by mistake! ;)
This will be used by Testman.
Previously, it had to translate the short hash from the build number to a long hash, but such a database (GitInfo) only exists for commits in the master branch.
