Instead, assume that bus_dmamap_load() succeeeded (and thus that bus_dmamap_unload() should be called) if the bus address for a resource is non-zero, and assume that bus_dmamem_alloc() succeeded (and thus that bus_dmamem_free() should be called) if the virtual address for a resource is not NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | take advantage of it instead of duplicating it. This reduces the size of the i386 GENERIC kernel by about 4k. The only potential in-tree user left unconverted is xe(4), which generally should be changed to use miibus(4) instead of implementing PHY handling on its own, as otherwise it makes not much sense to add a dependency on miibus(4)/mii_bitbang(4) to xe(4) just for the MII bitbang'ing code. The common MII bitbang'ing code also is useful in the embedded space for using GPIO pins to implement MII access. - Based on lessons learnt with dc(4) (see r185750), add bus barriers to the MII bitbang read and write functions of the other drivers converted in order to ensure the intended ordering. Given that register access via an index register as well as register bank/window switching is subject to the same problem, also add bus barriers to the respective functions of smc(4), tl(4) and xl(4). - Sprinkle some const.

* - Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOPMarius Strobl2011-05-031-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (reporting IFM_LOOP based on BMCR_LOOP is left in place though as it might provide useful for debugging). For most mii(4) drivers it was unclear whether the PHYs driven by them actually support loopback or not. Moreover, typically loopback mode also needs to be activated on the MAC, which none of the Ethernet drivers using mii(4) implements. Given that loopback media has no real use (and obviously hardly had a chance to actually work) besides for driver development (which just loopback mode should be sufficient for though, i.e one doesn't necessary need support for loopback media) support for it is just dropped as both NetBSD and OpenBSD already did quite some time ago. - Let mii_phy_add_media() also announce the support of IFM_NONE. - Restructure the PHY entry points to use a structure of entry points instead of discrete function pointers, and extend this to include a "reset" entry point. Make sure any PHY-specific reset routine is always used, and provide one for lxtphy(4) which disables MII interrupts (as is done for a few other PHYs we have drivers for). This includes changing NIC drivers which previously just called the generic mii_phy_reset() to now actually call the PHY-specific reset routine, which might be crucial in some cases. While at it, the redundant checks in these NIC drivers for mii->mii_instance not being zero before calling the reset routines were removed because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. Consequently, NIC drivers now no longer should call mii_phy_reset() directly, so it was removed from EXPORT_SYMS. - Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe(). The purpose of that function is to perform the common steps to attach a PHY driver instance and to hook it up to the miibus(4) instance and to optionally also handle the probing, addition and initialization of the supported media. So all a PHY driver without any special requirements has to do in its bus attach method is to call mii_phy_dev_attach() along with PHY-specific MIIF_* flags, a pointer to its PHY functions and the add_media set to one. All PHY drivers were updated to take advantage of mii_phy_dev_attach() as appropriate. Along with these changes the capability mask was added to the mii_softc structure so PHY drivers taking advantage of mii_phy_dev_attach() but still handling media on their own do not need to fiddle with the MII attach arguments anyway. - Keep track of the PHY offset in the mii_softc structure. This is done for compatibility with NetBSD/OpenBSD. - Keep track of the PHY's OUI, model and revision in the mii_softc structure. Several PHY drivers require this information also after attaching and previously had to wrap their own softc around mii_softc. NetBSD/OpenBSD also keep track of the model and revision on their mii_softc structure. All PHY drivers were updated to take advantage as appropriate. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - According to IEEE 802.3-2002 the bits actually have to be reversed when mapping an OUI to the MII ID registers. All PHY drivers and miidevs where changed as necessary. Actually this now again allows to largely share miidevs with NetBSD, which fixed this problem already 9 years ago. Consequently miidevs was synced as far as possible. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

* bus_dma(9) conversion and make nge(4) work on all architectures.Pyun YongHyeon2009-05-212-823/+1642

Note, this is the same behavior as previous one but previously nge(4) didn't explicitly disable 64bit mode on DP83820. - Added Tx/Rx descriptor ring alignment requirements(8 bytes alignment). - Limit maximum number of Tx DMA segments to 16. In fact, controller does not seem to have limitations on number of Tx DMA segments but 16 should be enough for most cases and m_collapse(9) will handle highly fragmented frames without consuming a lot of CPU cycles. - Added Rx buffer alignment requirements(8 bytes alignment). This means driver should fixup received frames to align on 16bits boundary on strict-alignment architectures. - Nuked driver private data structure in descriptor ring. - Added endianness support code in Tx/Rx descriptor access. o Prefer faster memory mapped register access to I/O mapped access. Added fall-back mechanism to use alternative register access. The hardware supports both memory and I/O mapped access. o Added suspend/resume methods but it wasn't tested as controller I have does not support PCI PME. o Removed swap argument in nge_read_eeprom() since endianness should be handled after reading EEPROM. o Implemented experimental 802.3x full-duplex flow-control. ATM it was commented out but will be activated after we have generic flow-control framework in mii(4) layer. o Rearranged promiscuous mode settings and simplified logic. o Always disable Rx filter prior to changing Rx filter functions as indicated in DP83820/DP83821 datasheet. o Added an explicit DELAY in timeout loop of nge_reset(). o Added a sysctl variable dev.nge.%d.int_holdoff to control interrupt moderation. Valid ranges are 1 to 255(default 1) in units of 100us. The actual delivery of interrupt would be delayed based on the sysctl value. The interface has to be brought down and up again before a change takes effect. With proper tuning value, users do not need to resort to polling(4) anymore. o Added ALTQ(4) support. o Added missing IFCAP_VLAN_HWCSUM as nge(4) can offload Tx/Rx checksum calculation on VLAN tagged frames as well as VLAN tag insertion/stripping. Also add IFCAP_VLAN_MTU capability as nge(4) can handle VLAN tagged oversized frames. o Fixed media header length for VLAN. o Rearranged nge_detach routine such that it's now used for general clean-up routine. o Enabled MWI. o Accessing EEPROM takes very long time so read 6 bytes ethernet address with one call instead of 3 separate accesses. o Don't set if_mtu in device attach, it's already set in ether_ifattach(). o Don't do any special things for TBI interface. Remove TBI specific media handling in the driver and have gentbi(4) handle it. Add glue code to read/write TBI PHY registers in miibus method. This change removes a lot of PHY handling code in driver and now its functionality is handled by mii(4). o Alignment fixup code is now applied only for strict-alignment architectures. Previously the code was applied for all architectures except i386. With this change amd64 will get instant Rx performance boost. o When driver fails to allocate a new mbuf, update if_qdrops so users can see what was wrong in Rx path. o Added a workaround for a hardware bug which resulted in short VLAN tagged frames(e.g. ARP) was rejected as if runt frame was received. With this workaround nge(4) now accepts the short VLAN tagged frame and nge(4) can take full advantage of hardware VLAN tag stripping. I have no idea how this bug wasn't known so far, without the workaround nge(4) may never work on VLAN environments. o Fixed Rx checksum offload logic such that it now honors active interface capability configured with ifconfig(8). o In nge_start()/nge_txencap(), always leave at least one free descriptor as indicated in datasheet. Without this the hardware would be confused with ring descriptor structure(e.g. no clue for the end of descriptor ring). o Removed dead-code that checks interrupts on PHY hardware. The code was designed to detect link state changes but it was disabled as driving nge_tick clock would break auto-negotiation timer. This code is no longer needed as nge(4) now uses mii(4) and link state change handling is done with mii callback. o Rearranged ethernet address programming logic such that it works on strict-alignment architectures. o Added IFCAP_VLAN_HWTAGGING/IFCAP_VLAN_HWCSUM handler in nge_ioctl() such that the functionality is configurable with ifconfig(8). DP83820/DP83821 can do checksum offload for VLAN tagged frames so enable Tx/Rx checksum offload for VLAN interfaces. o Simplified IFCAP_POLLING selection logic in nge_ioctl(). o Fixed module unload panic when bpf listeners are active. o Tx/Rx descriptor ring address uses 64bit DMA address for readability. High address part of DMA would be 0 as nge(4) disabled 64bit DMA transfers so it's ok for DP83821. o Removed volatile keyword in softc as bus_dmamap_sync(9) should take care of this. o Removed extra driver private structures in descriptor ring. These extra elements are not part of descriptor structure. Embedding private driver structure into descriptor ring is not good idea as its size may be different on 32bit/64bit architectures. o Added miibus_linkchg method handler to catch link state changes. o Removed unneeded nge_ifmedia in softc. All TBI access is handled in gentbi(4). There is no difference between TBI and non-TBI case now. o Removed "gigabit link up" message handling in nge_tick. Link state change notification is already performed by mii(4) and checking link state by accessing PHY registers in periodic timer handler of driver is wrong. All link state and speed/duplex monitoring should be handled in PHY driver. o Use our own timer for watchdog instead of if_watchdog/if_timer interface. o Added hardware MAC statistics counter, users canget current MAC statistics from dev.nge.%d.stats sysctl node(%d is unit number of a device). o Removed unused macros, NGE_LASTDESC, NGE_MODE, NGE_OWNDESC, NGE_RXBYTES. o Increased number of Tx/Rx descriptors from 128 to 256. From my experience on gigabit ethernet controllers, number of descriptors should be 256 or higher to get an optimal performance on gigabit link. o Increased jumbo frame length to 9022 bytes to cope with other gigabit ethernet drivers. Experimentation shows no problems with 9022 bytes. o Removed unused member variables in softc. o Switched from bus_space_{read|write}_4 to bus_{read|write}_4. o Added support for WOL.

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. No more tag memory allocation have to be done. Reviewed by: thompsa, yar Sponsored by: TCP/IP Optimization Fundraise 2005 Notes: svn path=/head/; revision=162375

| | | | | | | | | | | | | | | | | | - Use device_printf() and if_printf() and remove nge_unit. - Use callout_init_mtx() and remove nge_tick_locked() as nge_tick() is now always called with the driver lock held. - Use M_ZERO to contigmalloc() when allocating nge_ldata. It was possible for the random garbage to be used in certain cases otherwise. - Cleanup attach error handling including no longer leaking nge_ldata. - Add locking to the ifmedia callouts. - Lock accesses to if_hwassist and if_capenable in nge_ioctl().
