qec − QEC bus nexus device driver

CONFIG — Desktop SPARCsystems, SPARCsystem 600MP SERIES

device-driver qec

DESCRIPTION

The qec device driver is a bus nexus driver which provides basic support for the QEC hardware.  It is the parent of the be(4S), and qe(4S) leaf drivers.  The driver supports multiple SBusQuadEthernetController and SunFastEthernet SBus cards installed within the system.  It is not directly accessible to the user. 

DIAGNOSTICS

qec%d: Bad number of regs %d 
The SBus card has reported an invalid number of device registers. The QEC device is most likely bad. 

qec%d: Driver has no parent 
The driver doesn’t have a parent driver. This error is usually symptomatic of trouble elsewhere in the operating system.

qec%d: Failed to get driver private data 
The QEC initialization function could not recover its private data.  This error is usually symptomatic of trouble in the operating system or driver.  QEC device is most likely bad. 

qec%d: Global reset failed 
Could not reset the QEC device.  The QEC device is most likely bad. 

qec%d: Missing reg property! 
The devices register property is missing. The QEC device is most likely bad. 

qec%d: Not all children are detached 
An attempt was made to unload the driver before unloading the children’s drivers.  First unload the BE and the QE device drivers before trying to unload the QEC device driver. 

qec%d: Not used - SBus slot %d is slave-only 
The SBus card has been installed into a slot that cannot be used by a DMA master.  Move the SBus card to another slot.

qec%d: Unknown chip identification 
Driver does not know what type of MACE chip is being used.  Upgrading the driver may eliminate this error.

qec%d: map_regs failed 
The driver cannot allocate sufficient memory for resources. These messages occur when attempting to load the driver.  You will be unable to load the driver until sufficient memory becomes free.  Terminating unnecessary processes or unloading unused drivers are ways to free memory.
