Description
0x1c=0011100 Thresh 1 Event - Down
This event specifies that a memory management threshold was crossed down-
wards. The event information contains the LCD address.
0x1d=0011101 Thresh 1 Event - Up
This event specifies that a memory management threshold was crossed upwards.
The event information contains the LCD address.
0x1e=0011110 Thresh 2 Event - Down
This event specifies that a memory management threshold was crossed down-
wards. The event information contains the LCD address.
0x1f=0011111 Thresh 2 Event - Up
This event specifies that a memory management threshold was crossed upwards.
The event information contains the LCD address.
0x20=0100000 Transmit Complete
This event specifies that a packet/cell was successfully transmitted. The event
information contains a pointer to the buffer transmitted.
0x21=0100001 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=0100010 Transmit Bad
This event specifies that a packet was to be transmitted, but the buffer was marked
as bad, so was canceled. This is caused by getting a page fault when DMAing into
the transmit packet buffer. The event information contains a pointer to the bad
buffer.
0x23=0100011 Connection Closed
This event specifies that all packets for the given LCD have been transmitted. The
event information contains the LCD address.
0x24=0100100IBM3206K0424)
This event specifies that a TX DMA completed successfully. The event information
depends on how the DMA was set up. Event-identifier 0x64 is an alias.
0x25=0100101IBM3206K0424)
This event specifies that an RX DMA completed successfully. The event informa-
tion depends on how the DMA was set up. Event-identifier 0x65 is an alias.
0x26=0100110IBM3206K0424)
This event specifies that a TX DMA had errors. The event information depends on
how the DMA was set up. Event-identifier 0x66 is an alias.
0x27=0100111of IBM3206K0424)
This event specifies that an RX DMA had errors. The event information depends
on how the DMA was set up. Event-identifier 0x67 is an alias.
0x28=0101000Error
This event specifies that a TX DMA had a virtual error. The remainder of the DMA
descriptor was cancelled. The event information contains the DMA descriptor
address. Event-identifier 0x68 is an alias.
0x29=0101001 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 con-
tains the DMA descriptor address. Event-identifier 0x69 is an alias.
