* o Sort includes and add <endian.h> to support endianness.Pyun YongHyeon2008-08-212-367/+491
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Removed unneeded header files. o bus_dma(9) fix: - created parent tag with 1GB dma address limit with no alignment restrictions. - set 4096 alignment limit for Tx/Rx descriptor rings. - separate Rx buffer tag from Tx buffer tag such that Tx tag allows up-to 16 segments while Rx buffer tag only allows single segment. - it seems the controller has no alignment restrictions on Tx/Rx buffers. Remove ETHER_ALIGN alignment restriction in Tx/Rx buffers. - created a spare Rx dma map which would be used to cope with failure of loading a dma map. - make sure to load full Tx/Rx descriptor size for Tx/Rx descriptor dma maps, previously bfe(4) used to load single descriptor size for each descriptor rings. I have no idea how it could be run without problems. - don't blindly cast bus_addr_t type to 32bits in bfe_dma_map(). - created bfe_dma_free() to free allocated dma memory/tags. - make sure to invoke bus_dmamap_sync(9) before/after processing descriptor rings/buffers. Because the hardware has severe dma address space limitation, bounce-buffers would be always used on systems with more than 1GB memory during descriptors/buffers access. - added Tx descriptor ring initialization function, bfe_list_tx_init(). - moved producer/consumer index initialization to bfe_list_tx_init() and bfe_list_rx_init() from bfe_chip_reset(). - added bfe_discard_buf() which will update loaded descriptors without unloading/reloading the dma map to speed up error recovery. - implemented Tx side bus_dmamap_load_mbuf_sg(9). The number of segments allowed was chosen to be 16 which should be enough for non-TSO capable hardwares. Setting SOF bit of Tx descriptor is done in the last to avoid potential race. - don't give up sending frames in bfe_start() until the hardware lacks free descriptors. - added XXX comment to second kick command and possible workaround. - implemented Rx side bus_dmamap_load_mbuf_sg(9). - removed bfe_dma_map_desc() as it's not needed anymore after the conversion to bus_dmamap_load_mbuf_sg(9). - added endianness support. With this change bfe(4) should work on any architectures that can create bounce buffers within 1GB address range. - add missing bus_dmamap_sync() in bfe_tx_eof()/bfe_rx_eof(). o Use PCI_BAR instead of hardcoded value to set BARs. Simplified register access with bus_write_4(9)/bus_read_4(9) and removed bfe_btag, bfe_bhandle, bfe_vhandle in softc as it's not used anymore. o Reorder device detach logic such that bfe_detach() is also used for handling driver attach failure case. o Remove unnecessary KASSERT in bfe_detach(). o Remove bfe_rx_cnt, bfe_up, bfe_vpd_prodname, bfe_vpd_readonly in softc. It's not used at all. o Remove BFE_RX_RING_SIZE/BFE_RX_RING_SIZE/BFE_LINK_DOWN.

Reprogram MAC to appropriate duplex state. Flow-control configuration was also implemented but commented out at the moment.

* 1. Make sure that the TX and RX descriptor rings are 4096 byte aligned.Mike Silbersack2006-05-281-6/+21
| | | | | | | | | | | | | | | | | | | | | Also use BUS_DMA_ALLOCNOW to be on the safe side. 2. Look for the Descriptor Error, and Descriptor Protocol Error flags from the card, and down the interface if we detect either. #1 (along with fixes to busdma) makes sure that this card works in all memory situations. Prior to this change, it was just luck that 512 count RX/TX lists were properly aligned. Now we can use any size of RX/TX lists and still have them properly aligned. #2 ensures that we don't get into an endless interrupt storm if busdma fails us. Descriptor Protocol Error would occur if we misaligned the TX/RX rings, and Descriptor Error would occur if we tried to give the card descriptors or rings with addresses > 1G. Trying to reinitialize the card isn't going to fix these errors, hence we don't try. Notes: svn path=/head/; revision=159013

* Fix three more bugs in bfe:Mike Silbersack2006-05-042-17/+22
| | | | | | | | | | | | | | | | | - Fix bfe_encap so that it will pass the address of the mbuf back up to its caller if/when it modifies it, as it does when doing a m_defrag on a mbuf chain. - Make sure to unload the dmamap for ALL fragments of a packet, not just the first - Use BUS_DMA_NOWAIT for all bus_dmamap_load calls so that the allocation of the map is not delayed - this driver is not set up to handle such delays. - Reduce the number of RX and TX buffers bfe uses so that it does not use more bounce buffers than busdma is willing to allow it to use With these changes, the driver now works properly for a user with a 2GB system, and it also works on my system when the acceptable address range is lowered to 128MB. Previously, both of these setups would act up after a few minutes of activity. Notes: svn path=/head/; revision=158285

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-19/+29
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.
