This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

/*
* The Adaptec AIC-6915 "Starfire" is a 64-bit 10/100 PCI ethernet
* controller designed with flexibility and reducing CPU load in mind.
* The Starfire offers high and low priority buffer queues, a
* producer/consumer index mechanism and several different buffer
* queue and completion queue descriptor types. Any one of a number
* of different driver designs can be used, depending on system and
* OS requirements. This driver makes use of type0 transmit frame
* descriptors (since BSD fragments packets across an mbuf chain)
* and two RX buffer queues prioritized on size (one queue for small
* frames that will fit into a single mbuf, another with full size
* mbuf clusters for everything else). The producer/consumer indexes
* and completion queues are also used.
*
* One downside to the Starfire has to do with alignment: buffer
* queues must be aligned on 256-byte boundaries, and receive buffers
* must be aligned on longword boundaries. The receive buffer alignment
* causes problems on the Alpha platform, where the packet payload
* should be longword aligned. There is no simple way around this.
*
* For receive filtering, the Starfire offers 16 perfect filter slots
* and a 512-bit hash table.
*
* The Starfire has no internal transceiver, relying instead on an
* external MII-based transceiver. Accessing registers on external
* PHYs is done through a special register map rather than with the
* usual bitbang MDIO method.
*
* Acesssing the registers on the Starfire is a little tricky. The
* Starfire has a 512K internal register space. When programmed for
* PCI memory mapped mode, the entire register space can be accessed
* directly. However in I/O space mode, only 256 bytes are directly
* mapped into PCI I/O space. The other registers can be accessed
* indirectly using the SF_INDIRECTIO_ADDR and SF_INDIRECTIO_DATA
* registers inside the 256-byte I/O window.

Depend on miibus. Note that if_aue doesn't strictly depend on usb because it uses the method interface for calls rather than using internal symbols, and because it's a child driver of usb and therefore will not try and do anything unless the parent usb code is loaded at some point. if_aue does strictly depend on miibus as it will fail to link if it is missing.

DRIVER_MODULE(sf, pci, sf_driver, sf_devclass, 0, 0);
Un-do the changes to the DRIVER_MODULE() declarations in these drivers. This whole idea isn't going to work until somebody makes the bus/kld code smarter. The idea here is to change the module's internal name from "foo" to "if_foo" so that ifconfig can tell a network driver from a non-network one. However doing this doesn't work correctly no matter how you slice it. For everything to work, you have to change the name in both the driver_t struct and the DRIVER_MODULE() declaration. The problems are: - If you change the name in both places, then the kernel thinks that the device's name is now "if_foo", so you get things like: if_foo0: <FOO ethernet> irq foo at device foo on pcifoo if_foo0: Ethernet address: foo:foo:foo:foo:foo:foo This is bogus. Now the device name doesn't agree with the logical interface name. There's no reason for this, and it violates the principle of least astonishment. - If you leave the name in the driver_t struct as "foo" and only change the names in the DRIVER_MODULE() declaration to "if_foo" then attaching drivers to child devices doesn't work because the names don't agree. This breaks miibus: drivers that need to have miibuses and PHY drivers attached never get them. In other words: damned if you do, damned if you don't. This needs to be thought through some more. Since the drivers that use miibus are broken, I have to change these all back in order to make them work again. Yes this will stop ifconfig from being able to demand load driver modules. On the whole, I'd rather have that than having the drivers not work at all.

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

Try to create some sort of consistency in how the routings to find the multicast hash are written. There are still two distinct algorithms used, and there actually isn't any reason each driver should have its own copy of this function as they could all share one copy of it (if it grew an additional argument).

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

This corrects a problem that I noticed where my ANA-62022 board failed to correctly program the full duplex bit in the macconfig1 register when the interface was brought up. Running ifconfig sf0 would mask this problem in some cases because polling the PHY status would cause the miibus code to notice that full duplex was now needed and the statchg callback would be invoked to configure the duplex setting. However it would still get it wrong other times. Also changed sf_miibus_statchg() to program the IPG register to match the duplex setting in accordance with Adaptec manual's recommendations (0x15 for full duplex, 0x11 for half duplex).

Running ifconfig sf0 would mask this problem in some cases because polling the PHY status would cause the miibus code to notice that full duplex was now needed and the statchg callback would be invoked to configure the duplex setting. However it would still get it wrong other times. Also changed sf_miibus_statchg() to program the IPG register to match the duplex setting in accordance with Adaptec manual's recommendations (0x15 for full duplex, 0x11 for half duplex).

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

Modify the Adaptec "starfire" driver to reset the PHY on the MII bus before selecting a mode. The Seeq PHY chips on the Adaptec cards that use the AIC-6915 controller seem to need it in order to get them to change modes correctly.

Minor tweak: the subsystem device ID code for the quad port 62044 card is documented to be 0x18 in the Adaptec manual, however there appears to be a newer board rev with code 0x19. I added a #define for this and updated the probe code so that this board will be properly identified in the probe messages. (Currently it's just identified generically as an AIC-6915 chip.)

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

Clean up locking and resource management for pci/if_* - Remove locking of the softc in the attach method, instead depending on bus_setup_intr being at the end of attach (delaying interrupt enable until after ether_ifattach is called) - Call *_detach directly in the error case of attach, depending on checking in detach to only free resources that were allocated. This puts all resource freeing in one place, avoiding thinkos that lead to memory leaks. - Add bus_child_present check to calls to *_stop in the detach method to be sure hw is present before touching its registers. - Remove bzero softc calls since device_t should do this for us. - dc: move interrupt allocation back where it was before. It was unnecessary to move it. This reverts part of 1.88 - rl: move irq allocation before ether_ifattach. Problems might have been caused by allocating the irq after enabling interrupts on the card. - rl: call rl_stop before ether_ifdetach - sf: call sf_stop before ether_ifdetach - sis: add missed free of sis_tag - sis: check errors from tag creation - sis: move dmamem_alloc and dmamap_load to happen at same time as tag creation - sk: remove duplicate initialization of sk_dev - ste: add missed bus_generic_detach - ti: call ti_stop before ether_ifdetach - ti: add missed error setting in ti_rdata alloc failure - vr: add missed error setting in I/O, memory mapping cases - xl: add missed error setting in I/O, memory mapping cases - xl: remove multi-level goto on attach failure - xl: move dmamem_alloc and dmamap_load to happen at same time as tag creation - Calls to free(9) are unconditional because it is valid to call free with a null pointer.

First round of converting network drivers from spls to mutexes. This takes care of all the 10/100 and gigE PCI drivers that I've done. Next will be the wireless drivers, then the USB ones. I may pick up some stragglers along the way. I'm sort of playing this by ear: if anyone spots any places where I've screwed up horribly, please let me know.

* The starfire is programmed to use 'normal' mode for packet reception,

* read the RX completion consumer and producer indexes and the RX buffer
* producer index, plus the RX completion consumer and RX buffer producer
* indexes have to be updated. It would have been easier if Adaptec had
* put each index in a separate register, especially given that the damn
* NIC has a 512K register space.
*
* In spite of all the lovely features that Adaptec crammed into the 6915,
* it is marred by one truly stupid design flaw, which is that receive
* buffer addresses must be aligned on a longword boundary. This forces
* the packet payload to be unaligned, which is suboptimal on the x86 and
* completely unuseable on the Alpha. Our only recourse is to copy received
* packets into properly aligned buffers before handing them off.

Change m_devget()'s outdated and unused `offset' argument to actually mean something: offset into the first mbuf of the target chain before copying the source data over. Make drivers using m_devget() with a first argument "data - ETHER_ALIGN" to use the offset argument to pass ETHER_ALIGN in. The way it was previously done is potentially dangerous if the source data was at the top of a page and the offset caused the previous page to be copied (if the previous page has not yet been appropriately mapped). The old `offset' argument in m_devget() is not used anywhere (it's always 0) and dates back to ~1995 (and earlier?) when support for ethernet trailers existed. With that support gone, it was merely collecting dust. Tested on alpha by: jlemon Partially submitted by: jlemon Reviewed by: jlemon MFC after: 3 weeks

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256.

First round of converting network drivers from spls to mutexes. This takes care of all the 10/100 and gigE PCI drivers that I've done. Next will be the wireless drivers, then the USB ones. I may pick up some stragglers along the way. I'm sort of playing this by ear: if anyone spots any places where I've screwed up horribly, please let me know.

Modify the Adaptec "starfire" driver to reset the PHY on the MII bus before selecting a mode. The Seeq PHY chips on the Adaptec cards that use the AIC-6915 controller seem to need it in order to get them to change modes correctly. This corrects a problem that I noticed where my ANA-62022 board failed to correctly program the full duplex bit in the macconfig1 register when the interface was brought up. Running ifconfig sf0 would mask this problem in some cases because polling the PHY status would cause the miibus code to notice that full duplex was now needed and the statchg callback would be invoked to configure the duplex setting. However it would still get it wrong other times. Also changed sf_miibus_statchg() to program the IPG register to match the duplex setting in accordance with Adaptec manual's recommendations (0x15 for full duplex, 0x11 for half duplex).

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model. The Starfire would be a very nice chip were it not for the fact that receive buffers have to be longword aligned. This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

Modify the Adaptec "starfire" driver to reset the PHY on the MII bus before selecting a mode. The Seeq PHY chips on the Adaptec cards that use the AIC-6915 controller seem to need it in order to get them to change modes correctly. This corrects a problem that I noticed where my ANA-62022 board failed to correctly program the full duplex bit in the macconfig1 register when the interface was brought up. Running ifconfig sf0 would mask this problem in some cases because polling the PHY status would cause the miibus code to notice that full duplex was now needed and the statchg callback would be invoked to configure the duplex setting. However it would still get it wrong other times. Also changed sf_miibus_statchg() to program the IPG register to match the duplex setting in accordance with Adaptec manual's recommendations (0x15 for full duplex, 0x11 for half duplex).

As suggested by phk, unconditionalize BPF support in these drivers. Since there are stubs compiled into the kernel if BPF support is not enabled, there aren't any problems with unresolved symbols. The modules in /modules are compiled with BPF support enabled anyway, so the most this will do is bloat GENERIC a little.

After one more day of testing, make what I hope are the final tweaks to prevent/workaround TX lockups in this driver. The secret seems to be to not let the TX DMA queue become too full. If we have too many packets in the queue, we should wait for them to drain a bit before trying to queue more. This should prevent the lockup from occurring, and if it does occur, there is special code in sf_start() to kick the NIC in the head and get it going again. Special thanks to Glen Neff for helping me test this fix.

This requires buffer copying in order to achieve proper payload alignment on the alpha. Payload alignment is enforced on both the alpha and x86 platforms. The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

Modify the Adaptec "starfire" driver to reset the PHY on the MII bus before selecting a mode. The Seeq PHY chips on the Adaptec cards that use the AIC-6915 controller seem to need it in order to get them to change modes correctly. This corrects a problem that I noticed where my ANA-62022 board failed to correctly program the full duplex bit in the macconfig1 register when the interface was brought up. Running ifconfig sf0 would mask this problem in some cases because polling the PHY status would cause the miibus code to notice that full duplex was now needed and the statchg callback would be invoked to configure the duplex setting. However it would still get it wrong other times. Also changed sf_miibus_statchg() to program the IPG register to match the duplex setting in accordance with Adaptec manual's recommendations (0x15 for full duplex, 0x11 for half duplex).

The Starfire has several different DMA descriptor formats and transfer mechanisms. This driver uses frame descriptors for transmission which can address up to 14 packet fragments, and a single fragment descriptor for receive. It also uses the producer/consumer model and completion queues for both transmit and receive. The transmit ring has 128 descriptors and the receive ring has 256. This driver supports both FreeBSD/i386 and FreeBSD/alpha, and uses newbus so that it can be compiled as a loadable kernel module. Support for BPF and hardware multicast filtering is included.

This commit adds device driver support for Adaptec Duralink PCI fast ethernet controllers based on the AIC-6915 "Starfire" controller chip. There are single port, dual port and quad port cards, plus one 100baseFX card. All are 64-bit PCI devices, except one single port model.
