Changeset 125 for trunk/src/os2ahci/ioctl.h

Timestamp:

Message:

Version 1.21

---

• Triggered by reports of performance loss with NCQ
• New command line flag "/F" to force using write buffers even when upstream I/O requested non-buffered I/O; the primary purpose of this flag is to debug the NCQ performance drop but the flag may or may not remain.
