Changeset 20167 in vbox for trunk/src/VBox/VMM

Timestamp:

Jun 1, 2009 8:25:54 PM (16 years ago)

Author:

Message:

First part of the PDMAsyncCompletion rewrite:

• The Host specific parts in VMM are deleted (moved into Runtime)
• Implemented a incomplete manager for file operations:
  • A slightly tested failsafe method to do operations is implemented using the synchronous RTFile* API. The failsafe method will be always used if the host has no support for async I/O or something bad happens during the operation reducing the risk of VM termination
• Changed the testcase and drivers to use the new API
• Removed the now obsolete async transport driver
• Removed the obsolete raw async image driver
• Removed the fault injection driver (useless from the beginning)

Location:

trunk/src/VBox/VMM

Files:

• Makefile.kmk (modified) (1 diff)
• PDMAsyncCompletionFile.cpp (added)
• PDMDriver.cpp (modified) (2 diffs)
• PDMInternal.h (modified) (2 diffs)
