* DMA synchronization fixes:Xin LI2009-05-181-16/+13
| | | | | | | | | | | | | | | | | | - In bce_rx_intr(), use BUS_DMASYNC_POSTREAD instead of BUS_DMASYNC_POSTWRITE, as we want to "read" from the rx page chain pages. - Document why we need to do PREWRITE after we have updated the rx page chain pages. - In bce_intr(), use BUS_DMASYNC_POSTREAD and BUS_DMASYNC_PREREAD when before and after CPU "reading" the status block. - Adjust some nearby style mismatches/etc. Pointed out by: yongari Approved by: davidch (no objection) but bugs are mine :) Notes: svn path=/head/; revision=192281

| | | | | | | | | | | | | | | aligned on an 8 byte boundary. Prior to rev 1.36 this wasn't a problem because mbuf clusters tend be naturally aligned. The switch to using split buffers with the first buffer being the embedded data area of the mbuf has broken this assumption, at least on i386, causing a complete failure of RX functionality. Fix this for now by using a full cluster for the first RX buffer. A more sophisticated approach could be done with the old buffer scheme to realign the m_data pointer with m_adj(), but I'm also not clear on performance benefits of this old scheme or the performance implications of adding an m_adj() call to every allocation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Updated copyright date to 2007. Tested with BCM5706 A3. Added ID for BCM5708 B2. Removed unused driver version string. Modified BCE_PRINTF macro to automatically fill-in the sc pointer. Fixed a kernel panic when the driver was loaded as a module from the command-line because the MII bus pointer was null (i.e. the MII bus hadn't been enumerated yet). Added fix proposed by Vladimir Ivanov <wawa@yandex-team.ru> to prevent driver state corruption when releasing the lock during the ISR in bce_rx_intr() to send packets up the stack. Added new TX chain and register read sysctl interfaces for debugging. Cleaned up formatting for various other debug routines. Added a new statistic maintained by firmware which tracks the number of received packets dropped because no receive buffers are available. Notes: svn path=/head/; revision=169271

| | | | | | | | | | | | | | | | | | | | | | | descriptor's mbuf pointer to see if the transmit ring is full. The mbuf pointer is set only in the last descriptor of a multi-descriptor packet. By relying on the mbuf pointers of the earlier descriptors, the driver would sometimes overwrite a descriptor belonging to a packet that wasn't completed yet. Also, tx_chain_prod wasn't updated inside the loop, causing the wrong descriptor to be checked after the first iteration. The upshot of all this was the loss of some transmitted packets at medium to high packet rates. In bce_tx_encap, remove a couple of old statements that shuffled around the tx_mbuf_map pointers. These now correspond 1-to-1 with the transmit descriptors, and they are not supposed to be changed. Correct a couple of inaccurate comments. MFC after: 1 month Notes: svn path=/head/; revision=164327

This check should probably be moved up to bce_start_locked at some point, as it'll make the loop up there slightly more efficient, and will eliminate a costly set of busdma operations when the ring is full. But this works for now. This makes all of my UDP torture tests work. I'll cautiously say that it might even work for other users now. Feedback is appreciated. Notes: svn path=/head/; revision=163558

* Overhaul the transmit and dma paths:Scott Long2006-10-151-203/+121
| | | | | | | | | | | | | | | | | | | | | - Use bus_dmamap_load_mbuf_sg() to eliminate the need for the callback and all of the extra bookkeeping associated with it. - Eliminate the bce_dmamap_arg structure and streamline the memory allocation routines to not need it. This does change some of the debugging messages. - Refactor the loop that fills the buffer descriptor so that it can be done with a single set of logic in a single loop instead of two sets of logic. - Eliminate the need to cache and pass descriptor indexes between the start loop and the encap function. - Change the start loop to always check the ifnet sendq for more work. This significantly helps the driver withstand large UDP workloads, though it's still not perfect. I suspect the remaining work lies with handling the OACTIVE flag, and also in possibly streamlining the interrupt handler some. It is, however, nearly on par with the other popular gigabit drivers in terms of stability now. Notes: svn path=/head/; revision=163393

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | m_pkthdr.ether_vlan. The presence of the M_VLANTAG flag on the mbuf signifies the presence and validity of its content. Drivers that support hardware VLAN tag stripping fill in the received VLAN tag (containing both vlan and priority information) into the ether_vtag mbuf packet header field: m->m_pkthdr.ether_vtag = vlan_id; /* ntohs()? */ m->m_flags |= M_VLANTAG; to mark the packet m with the specified VLAN tag. On output the driver should check the mbuf for the M_VLANTAG flag to see if a VLAN tag is present and valid: if (m->m_flags & M_VLANTAG) { ... = m->m_pkthdr.ether_vtag; /* htons()? */ ... pass tag to hardware ... } VLAN tags are stored in host byte order. Byte swapping may be necessary. (Note: This driver conversion was mechanic and did not add or remove any byte swapping in the drivers.) Remove zone_mtag_vlan UMA zone and MTAG_VLAN definition.
