This turns off mountmgr listening on new devices. Now
BTRFS will only be mounted on demand when OS asks for it. RAID
is not going to work this way probably (have anybody checked it at all?)
This is a temporary workaround for CORE-17469
Spinlocks are not reentrant (and this is done a lot), using them forces us to have
an horrible hack in the kernel, which unschedules threads which are at DISPATCH_LEVEL
thus allowing another thread to take ownership of the spinlock while the unscheduled
thread should already hold it.
CORE-6473
This speeds up boot a bit and also decreases binary size.
- Introduce a new CMake define ISAPNP_ENABLE that defined only in x86 platform
when ISA PnP is supported.
Rework the hardware support code to avoid unneeded transitions
between configuration states.
- Only call WaitForKey when needed.
- Each PnP state transition causes the bus to move to WaitForKey state.
Besides, deactivate logical device during processing remove request.
- Fix empty resource descriptors being created.
- Properly support IRQ descriptors.
- Introduce four helpers made to help search descriptors
in the logical device's requirements.
- Implement support for memory descriptors and alternative configurations.
- DMA descriptors are always DMA_8.
- Support all resource descriptors.
- Optimize card identification.
- Detect cards that is no longer present on the bus.
- Deactivate cards after the identification phase; they will be activated
by start device IRP.
- Provide a device description and compatible IDs to the device manager.
- Prevent duplicate IDs across multiple logical devices.
- Suppress warning about the usage of literals in port addresses.
- Implement device removal.
- Finish the Read Port special handling
introduced in 21514e473f.
- Gracefully handle low memory situations.
- Implement IRQ translator.
- Correctly stub power IRP handling.
- Remove unneeded dispatch routines; implement WMI IRP handling.
- Do not handle requests like WRITE_CONFIG.
- Add a signature member to device extensions to make checks clearer.
This PDO is created only once during start of first FDO.
Other buses will remain in an inactive state until
the first FDO receives a remove request.
CORE-17034
- Add SAL2 annotations.
- Use RTL_NUMBER_OF macro in kernel mode.
- Use better function/member names.
- Less hardcoded values.
- Add license information. See commit
d9face83c6 for details.
No functional changes.
I am not sure why this line was added.
I don't know how I could improve that case.
Then, disable it, for the time being.
Addendum to 4b9cf2e (r71252). CORE-12441 CORE-17371
Some virtual machines errorneously expose null PCI device function
on PIIX4 chipset where an USB controller should normally reside.
Windows pci.sys driver does not enumerate these devices.
Affected virtual machines:
- Connectix Virtual PC 5.1.370
- Connectix Virtual PC 5.2.418
- Microsoft Virtual PC 2004 SP1 (5.3.582.27)
- Microsoft Virtual PC 2007 SP1 (6.0.156.0)
Non-affected virtual machines:
- Connectix Virtual PC 4.0
- Microsoft Hyper-V
Fixes CORE-17636.
Do not treat target device change notification as
DEVICE_INTERFACE_CHANGE_NOTIFICATION. The notification have to be
unregistered while handling GUID_DEVICE_INTERFACE_REMOVAL, so
GUID_TARGET_DEVICE_REMOVE_COMPLETE should never be sent to mountmgr in a
normal case.
CORE-16106
- Do not access uninitialized SymlinkInformation on failure case
and just return
- Do not make an assumption that MOUNTMGR_TARGET_NAME has a zero-string
From MSDN:
It is an error to call KeReleaseSpinLockFromDpcLevel if the specified spin lock was acquired by calling KeAcquireSpinLock because the caller's original IRQL is not restored, which can cause deadlocks or fatal page faults.
- Use PnP storage class drivers
- Make partmgr an upper filter driver for Disk class
- Fill upper filters in txtsetup and usetup/devinst
- Add cdrom driver to the critical device database
CORE-6264
- Pass all SRB flags which Windows scsiport passes
- Correctly reset the queue after completion
This fixes the bug when MS cdrom driver hangs after media ejection
Basic functions are implemented in order to work in PnP stack,
only legacy (non-pnp) miniport drivers are supported.
Tested mostly with uniata
CORE-17132
This driver works as complement to disk.sys/classpnp.sys from Windows 10
Manages partition PDOs and exposes them as volumes to mountmgr.sys.
The driver is almost complete, just some minor IOCTLs missing (will be
added on demand)
- ReparseFile was concatenated with itself, instead of ReparseIndex
- Meanwhile, use RtlAppendUnicodeStringToString for concatenating
strings instead of raw memory operations
This function may stuck during device installation if there are issues
with interrupts (or with a device itself).
This fixes the boot on my testing ThinkPad x60s
- 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
This avoids blocking all Ex worker threads in fastfat, thereby making Cc
unable to issue the lazy writes that would unblock those workers.
This is more or less directly taken from fastfat_new.
in favor of add_compile_options and the like with generator expressions
Also take this as an opportunity to remove the C++11 standard hack, GCC 8 now defaults to C++14
Instead of messing with global variables and the like, we introduce two target properties:
- WITH_CXX_EXCEPTIONS: if you want to use C++ exceptions
- WITH_CXX_RTTI: if you need RTTI in your module
You can use the newly introduced set_target_cpp_properties function, with WITH_EXCEPTIONS and WITH_RTTI arguments
We also introduce two libraries :
- cpprt: for C++ runtime routines
- cppstl: for the C++ standard template library
NB: On GCC, this requires to create imported libraries with the related built-in libraries:libsupc++, limingwex, libstdc++
Finally, we manage the relevant flags with the ad-hoc generator expressions
So, if you don't need exceptions, nor RTTI, nor use any runtime at all: you simply have nothing else to do than add your C++ file to your module
Cc may decide to process deferred writes any time, so the context might
already be freed by the time we return from CcDeferWrite.
Also mark the IRP as pending, since we're going to return STATUS_PENDING.

repository (microsoft/Windows-driver-samples@master/storage/class/cdrom/)
Synched with commit 96eb96dfb613e4c745db6bd1f53a92fe7e2290fc
The driver is written for Windows 10 and uses KMDF so we compile it with ntoskrnl_vista
and wdf01000 statically linked (for wdf01000 this will likely be changed in future)
CORE-17129
It adds basic input support for:
- Standard Bus Mouse
- Standard InPort Mouse
- Logitech Bus Mouse
- Microsoft Bus Mouse
- Microsoft InPort Mouse
- NEC PC-98 Bus Mouse
Untested on PC/AT, but should work.
