Description
0x1e=011110
Thresh 1 Event
This event specifies that a memory management threshold was
crossed. The event information contains the LCD address, and bit six
contains the direction (1 if up, 0 if down).
0x1f=011111
Thresh 2 Event
This event specifies that a memory management threshold was
crossed. The event information contains the LCD address, and bit six
contains the direction (1 if up, 0 if down).
0x20=100000
Transmit Complete
This event specifies that a packet/cell was successfully transmitted.
The event information contains a pointer to the buffer transmitted.
0x21=100001
Transmit Complete Buffer Freed
This event specifies that a packet/cell was successfully transmitted and
the buffer was freed back to pools. The event information contains a
pointer to the buffer transmitted.
0x22=100010
Transmit Bad
This event specifies that a packet was to be transmitted, but the buffer
was marked as bad, so was canceled. This is casued by getting a page
fault when DMAing into the transmit packet buffer. The event informa-
tion contains a pointer to the bad buffer.
0x23=100011
Connection Closed
This event specifies that all packets for the given LCD have been trans-
mitted. The event information contains the LCD address.
0x24=100100
TX DMA Complete (into IBM2520L8767)
This event specifies that a TX DMA completed successfully. The event
information depends on how the DMA was set up.
0x25=100101
RX DMA Complete (out of IBM2520L8767)
This event specifies that a RX DMA completed successfully. The event
information depends on how the DMA was set up.
0x26=100110
TX DMA Complete with Error (into
IBM2520L8767)
This event specifies that a TX DMA had errors. The event information
depends on how the DMA was set up.
0x27=100111
RX DMA Complete with Error (out of
IBM2520L8767)
This event specifies that a RX DMA had errors. The event information
depends on how the DMA was set up.
0x28=101000
TX DMA Complete with Virtual Error
This event specifies that a TX DMA had a virtual error. The reminder of
the DMA descriptor was cancelled. The event information contains the
DMA descriptor address.
0x29=101001
DMA Desc has Zero Address
This event specifies that a DMA descriptor source destination address
was zero. The remainder of the DMA descriptor was cancelled. The
event information contains the DMA descriptor address.
