- Convert PARTITION_TABLE_OFFSET to the number of bytes instead of
(number of bytes) / 2. This avoids many confusing casts
- Use a cache aligned buffer for MBR
- BUGFIX: do not call IoGetRelatedTargetDevice while guarded mutex is acquired
(the function issues an APC, but they are disabled inside a critical section)
- BUGFIX: only the beginning of a structure for GUID_PNP_CUSTOM_NOTIFICATION was copied and queued.
Just pass it as-is to a subscriber, without copying
- Don't convert event GUID to string, store and compare GUID struct itself
- Split IopNotifyPlugPlayNotification into 3 functions for each type of notification
(less stack usage and for future changes)
- Move initialization code for notifications into a separate routine
- Use separate lists and locks for every type of notification
- Put "TargetDeviceChange" notifications into their place inside DEVICE_NODE
- Change INIT_FUNCTION and INIT_SECTION to CODE_SEG("INIT") and DATA_SEG("INIT") respectively
- Remove INIT_FUNCTION from function prototypes
- Remove alloc_text pragma calls as they are not needed anymore
Introduce the PiPerformSyncDeviceAction routine for queuing
synchronous device actions
Change all kernel code to use PiPerformSyncDeviceAction and
PiQueueDeviceAction for device enumeration
CORE-10456
If SEH is used in a C trap handler, the exception frame will be
registered before the call to KiEnterTrap, which means we save
the wrong trap handler. We'll therefore also restore this wrong
frame for the excepting code, resulting in a stale SEH chain.
We avoid this problem by saving the handler in the assembly
trap entry code instead of from C. While SEH in a C trap handler
should now theoretically be safe, we still forbid it through
asserts in the C KiEnterTrap variants to make any potential
future problems more obvious. Should this functionality be
needed at some point and deemed safe, these asserts can then be
removed.
- Improve the device action worker to support more than just a single action
- Move the action queue code from IoInvalidateDeviceRelations to a new function IopQueueDeviceAction.
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().
- KD64: Update the list of supported Debug Filter Masks (KdComponentTable)
with the more up-to-date one from KDBG, that includes some components
that have been added in Vista+, but some of which we also use in ReactOS.
- NtQueryDebugFilterState(), NtSetDebugFilterState() and KdpPrint():
Add the Vista+ behaviour or falling back to the DEFAULT component ID
settings for unknown Components (compiled in only wheen NTDDI_VERSION >= NTDDI_VISTA).
+ Remove redundant comments and update these functions with SAL2 annotations.
- KDBG: Add extra documentation for the debug filter components list.
- CONFIG: Load all the supported Debug Filter Masks settings from the
registry.
- 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.
