IV. UTILITIES & DRIVERS
Event Logging
This release has been extended to register a number of event log errors and warnings
when problems are encountered. The events that can be logged include:
•
no DMA support has been configured
•
no interrupt driven DMA has been configured
•
a non-cache coherent PCI bus has been detected which results in uncached
DMA buffers.
•
fewer than the required number of DMA buffers have been allocated.
After booting the driver it is advisable to check the system event log to determine
the characteristics of your machine. For example, if an event log indicates that inter-
rupt driven DMA has not been configured, this may be because the BIOS has not
been configured for PCI interrupts. This would also be an indication that perfor-
mance monitoring will not provide meaningful results since the % busy counter
depends on DMA interrupts working.
To view the system event log, run the Event Viewer from the Administrative Tools
program group. From the Log menu ensure that the System Log has been selected.
Look for events with the Source type glint. Double click on these events to read the
event message.
If no glint events are logged then everything is working perfectly. In this case inter-
rupts are working, all DMA buffers have been allocated and the PCI bus is cache
coherent.
