Board Compatibility - -This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's -single-chip fast Ethernet controller for PCI, as used on the Intel -EtherExpress Pro 100 adapter. - -II. Board-specific settings - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS should be set to assign the -PCI INTA signal to an otherwise unused system IRQ line. While it's -possible to share PCI interrupt lines, it negatively impacts performance and -only recent kernels support it. - -III. Driver operation - -IIIA. General -The Speedo3 is very similar to other Intel network chips, that is to say -"apparently designed on a different planet". This chips retains the complex -Rx and Tx descriptors and multiple buffers pointers as previous chips, but -also has simplified Tx and Rx buffer modes. This driver uses the "flexible" -Tx mode, but in a simplified lower-overhead manner: it associates only a -single buffer descriptor with each frame descriptor. - -Despite the extra space overhead in each receive skbuff, the driver must use -the simplified Rx buffer mode to assure that only a single data buffer is -associated with each RxFD. The driver implements this by reserving space -for the Rx descriptor at the head of each Rx skbuff. - -The Speedo-3 has receive and command unit base addresses that are added to -almost all descriptor pointers. The driver sets these to zero, so that all -pointer fields are absolute addresses. - -The System Control Block (SCB) of some previous Intel chips exists on the -chip in both PCI I/O and memory space. This driver uses the I/O space -registers, but might switch to memory mapped mode to better support non-x86 -processors. - -IIIB. Transmit structure - -The driver must use the complex Tx command+descriptor mode in order to -have a indirect pointer to the skbuff data section. Each Tx command block -(TxCB) is associated with two immediately appended Tx Buffer Descriptor -(TxBD). A fixed ring of these TxCB+TxBD pairs are kept as part of the -speedo_private data structure for each adapter instance. - -The newer i82558 explicitly supports this structure, and can read the two -TxBDs in the same PCI burst as the TxCB. - -This ring structure is used for all normal transmit packets, but the -transmit packet descriptors aren't long enough for most non-Tx commands such -as CmdConfigure. This is complicated by the possibility that the chip has -already loaded the link address in the previous descriptor. So for these -commands we convert the next free descriptor on the ring to a NoOp, and point -that descriptor's link to the complex command. - -An additional complexity of these non-transmit commands are that they may be -added asynchronous to the normal transmit queue, so we disable interrupts -whenever the Tx descriptor ring is manipulated. - -A notable aspect of these special configure commands is that they do -work with the normal Tx ring entry scavenge method. The Tx ring scavenge -is done at interrupt time using the 'dirty_tx' index, and checking for the -command-complete bit. While the setup frames may have the NoOp command on the -Tx ring marked as complete, but not have completed the setup command, this -is not a problem. The tx_ring entry can be still safely reused, as the -tx_skbuff[] entry is always empty for config_cmd and mc_setup frames. - -Commands may have bits set e.g. CmdSuspend in the command word to either -suspend or stop the transmit/command unit. This driver always flags the last -command with CmdSuspend, erases the CmdSuspend in the previous command, and -then issues a CU_RESUME. -Note: Watch out for the potential race condition here: imagine - erasing the previous suspend - the chip processes the previous command - the chip processes the final command, and suspends - doing the CU_RESUME - the chip processes the next-yet-valid post-final-command. -So blindly sending a CU_RESUME is only safe if we do it immediately after -after erasing the previous CmdSuspend, without the possibility of an -intervening delay. Thus the resume command is always within the -interrupts-disabled region. This is a timing dependence, but handling this -condition in a timing-independent way would considerably complicate the code. - -Note: In previous generation Intel chips, restarting the command unit was a -notoriously slow process. This is presumably no longer true. - -IIIC. Receive structure - -Because of the bus-master support on the Speedo3 this driver uses the new -SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer. -This scheme allocates full-sized skbuffs as receive buffers. The value -SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to -trade-off the memory wasted by passing the full-sized skbuff to the queue -layer for all frames vs. the copying cost of copying a frame to a -correctly-sized skbuff. - -For small frames the copying cost is negligible (esp. considering that we -are pre-loading the cache with immediately useful header information), so we -allocate a new, minimally-sized skbuff. For large frames the copying cost -is non-trivial, and the larger copy might flush the cache of useful data, so -we pass up the skbuff the packet was received into. - -IV.
