Log:
[KS]
- Fix several bugs in KsProbeStreamIrp
- If requestor is KernelMode - just save a pointer in Irp->AssociatedIrp.SystemBuffer
(currently not used)
- If requestor is UserMode mark irp as buffered. Also set Flag IRP_INPUT_OPERATION when
the ioctl is IOCTL_KS_READ_STREAM. This is important to propagate modifications to
KSSTREAM_HEADERS (in particular DataUsed member)
- ReactOS KS can now be used in WinXP in combination with KSStudio. In order to make it
fully work, ks needs to implement software bus functions
[PORTCLS]
- Rewrite internal irp queue handling
- It now supports multiple KSSTREAM_HEADERs per Irp, variable sized KSSTREAM_HEADERs per
irp.
- Store the mapped virtual address not in the KSSTREAM_HEADER, as user programs will
receive then invalid addresses
- Add checks whether this irp is for an sink pin or source pin
- Fix multiple bugs when the pin is looped buffer mode (How did this work before?)
- ReactOS portcls + WinXP now properly works with audio recording
[WDMAUD_KERNEL]
- Don't free associated stream header anymore
- Tested with VBox 3.2.10 + VmWare Player 3.1.2 + WinXP
