The BCM5700, sometimes refered to as the Tigon III, has + * two on-board MIPS R4000 CPUs and can have as much as 16MB of external + * SSRAM. The BCM5700 supports TCP, UDP and IP checksum offload, jumbo + * frames, highly configurable RX filtering, and 16 RX and TX queues + * (which, along with RX filter rules, can be used for QOS applications). + * Other features, such as TCP segmentation, may be available as part + * of value-added firmware updates. Unlike the Tigon I and Tigon II, + * firmware images can be stored in hardware and need not be compiled + * into the driver. + * + * The BCM5700 supports the PCI v2.2 and PCI-X v1.0 standards, and will + * function in a 32-bit/64-bit 33/66Mhz bus, or a 64-bit/133Mhz bus. + * + * The BCM5701 is a single-chip solution incorporating both the BCM5700 + * MAC and a BCM5401 10/100/1000 PHY. Unlike the BCM5700, the BCM5701 + * does not support external SSRAM. + * + * Broadcom also produces a variation of the BCM5700 under the "Altima" + * brand name, which is functionally similar but lacks PCI-X support. + * + * Without external SSRAM, you can only have at most 4 TX rings, + * and the use of the mini RX ring is disabled. This seems to imply + * that these features are simply not available on the BCM5701. As a + * result, this driver does not implement any support for the mini RX + * ring. + */ + +#ifdef HAVE_KERNEL_OPTION_HEADERS +#include "opt_device_polling.h" +#endif + +#include <sys/param.h> +#include <sys/endian.h> +#include <sys/systm.h> +#include <sys/sockio.h> +#include <sys/mbuf.h> +#include <sys/malloc.h> +#include <sys/kernel.h> +#include <sys/module.h> +#include <sys/socket.h> +#include <sys/sysctl.h> + +#include <net/if.h> +#include <net/if_arp.h> +#include <net/ethernet.h> +#include <net/if_dl.h> +#include <net/if_media.h> + +#include <net/bpf.h> + +#include <net/if_types.h> +#include <net/if_vlan_var.h> + +#include <netinet/in_systm.h> +#include <netinet/in.h> +#include <netinet/ip.h> + +#include <machine/bus.h> +#include <machine/resource.h> +#include <sys/bus.h> +#include <sys/rman.h> + +#include <dev/mii/mii.h> +#include <dev/mii/miivar.h> +#include "miidevs.h" +#include <dev/mii/brgphyreg.h> + +#ifdef __sparc64__ +#include <dev/ofw/ofw_bus.h> +#include <dev/ofw/openfirm.h> +#include <machine/ofw_machdep.h> +#include <machine/ver.h> +#endif + +#include <dev/pci/pcireg.h> +#include <dev/pci/pcivar.h> + +#ifndef __rtems__ +#include <dev/bge/if_bgereg.h> +#else +#include "if_bgereg.h" +#endif + +#define BGE_CSUM_FEATURES (CSUM_IP | CSUM_TCP | CSUM_UDP) +#define ETHER_MIN_NOPAD (ETHER_MIN_LEN - ETHER_CRC_LEN) /* i.e., 60 */ + +MODULE_DEPEND(bge, pci, 1, 1, 1); +MODULE_DEPEND(bge, ether, 1, 1, 1); +MODULE_DEPEND(bge, miibus, 1, 1, 1); + +/* "device miibus" required.

The internal memory layout varies somewhat + * depending on whether or not we have external SSRAM attached. + * The BCM5700 can have up to 16MB of external memory. The BCM5701 + * is apparently not designed to use external SSRAM. The mappings + * up to the first 4 send rings are the same for both internal and + * external memory configurations. Note that mini RX ring space is + * only available with external SSRAM configurations, which means + * the mini RX ring is not supported on the BCM5701. + * + * The NIC's memory can be accessed by the host in one of 3 ways: + * + * 1) Indirect register access. The MEMWIN_BASEADDR and MEMWIN_DATA + * registers in PCI config space can be used to read any 32-bit + * address within the NIC's memory. + * + * 2) Memory window access. The MEMWIN_BASEADDR register in PCI config + * space can be used in conjunction with the memory window in the + * device register space at offset 0x8000 to read any 32K chunk + * of NIC memory. + * + * 3) Flat mode. If the 'flat mode' bit in the PCI state register is + * set, the device I/O mapping consumes 32MB of host address space, + * allowing all of the registers and internal NIC memory to be + * accessed directly. NIC memory addresses are offset by 0x01000000. + * Flat mode consumes so much host address space that it is not + * recommended. + */ +#define BGE_PAGE_ZERO 0x00000000 +#define BGE_PAGE_ZERO_END 0x000000FF +#define BGE_SEND_RING_RCB 0x00000100 +#define BGE_SEND_RING_RCB_END 0x000001FF +#define BGE_RX_RETURN_RING_RCB 0x00000200 +#define BGE_RX_RETURN_RING_RCB_END 0x000002FF +#define BGE_STATS_BLOCK 0x00000300 +#define BGE_STATS_BLOCK_END 0x00000AFF +#define BGE_STATUS_BLOCK 0x00000B00 +#define BGE_STATUS_BLOCK_END 0x00000B4F +#define BGE_SOFTWARE_GENCOMM 0x00000B50 +#define BGE_SOFTWARE_GENCOMM_SIG 0x00000B54 +#define BGE_SOFTWARE_GENCOMM_NICCFG 0x00000B58 +#define BGE_SOFTWARE_GENCOMM_FW 0x00000B78 +#define BGE_SOFTWARE_GENNCOMM_FW_LEN 0x00000B7C +#define BGE_SOFTWARE_GENNCOMM_FW_DATA 0x00000B80 +#define BGE_SOFTWARE_GENCOMM_END 0x00000FFF +#define BGE_UNMAPPED 0x00001000 +#define BGE_UNMAPPED_END 0x00001FFF +#define BGE_DMA_DESCRIPTORS 0x00002000 +#define BGE_DMA_DESCRIPTORS_END 0x00003FFF +#define BGE_SEND_RING_1_TO_4 0x00004000 +#define BGE_SEND_RING_1_TO_4_END 0x00005FFF + +/* Firmware interface */ +#define BGE_FW_DRV_ALIVE 0x00000001 +#define BGE_FW_PAUSE 0x00000002 + +/* Mappings for internal memory configuration */ +#define BGE_STD_RX_RINGS 0x00006000 +#define BGE_STD_RX_RINGS_END 0x00006FFF +#define BGE_JUMBO_RX_RINGS 0x00007000 +#define BGE_JUMBO_RX_RINGS_END 0x00007FFF +#define BGE_BUFFPOOL_1 0x00008000 +#define BGE_BUFFPOOL_1_END 0x0000FFFF +#define BGE_BUFFPOOL_2 0x00010000 /* or expansion ROM */ +#define BGE_BUFFPOOL_2_END 0x00017FFF +#define BGE_BUFFPOOL_3 0x00018000 /* or expansion ROM */ +#define BGE_BUFFPOOL_3_END 0x0001FFFF + +/* Mappings for external SSRAM configurations */ +#define BGE_SEND_RING_5_TO_6 0x00006000 +#define BGE_SEND_RING_5_TO_6_END 0x00006FFF +#define BGE_SEND_RING_7_TO_8 0x00007000 +#define BGE_SEND_RING_7_TO_8_END 0x00007FFF +#define BGE_SEND_RING_9_TO_16 0x00008000 +#define BGE_SEND_RING_9_TO_16_END 0x0000BFFF +#define BGE_EXT_STD_RX_RINGS 0x0000C000 +#define BGE_EXT_STD_RX_RINGS_END 0x0000CFFF +#define BGE_EXT_JUMBO_RX_RINGS 0x0000D000 +#define BGE_EXT_JUMBO_RX_RINGS_END 0x0000DFFF +#define BGE_MINI_RX_RINGS 0x0000E000 +#define BGE_MINI_RX_RINGS_END 0x0000FFFF +#define BGE_AVAIL_REGION1 0x00010000 /* or expansion ROM */ +#define BGE_AVAIL_REGION1_END 0x00017FFF +#define BGE_AVAIL_REGION2 0x00018000 /* or expansion ROM */ +#define BGE_AVAIL_REGION2_END 0x0001FFFF +#define BGE_EXT_SSRAM 0x00020000 +#define BGE_EXT_SSRAM_END 0x000FFFFF + + +/* + * BCM570x register offsets.

The array for one controller +is totally incompatible with any other controller, and if used will most likely +cause the controller to lock up and stop responding to the driver. Each micro +code array has its own parameter offsets (described below), and they each have +their own version number (which should not be confused with the version of the +rcvbundl.h file given above). + +*/ + + + +/************************************************************************* +* CPUSaver parameters +* +* All CPUSaver parameters are 16-bit literals that are part of a +* "move immediate value" instruction. By changing the value of +* the literal in the instruction before the code is loaded, the +* driver can change algorithm. +* +* CPUSAVER_DWORD - This is the location of the instruction that loads +* the dead-man timer with its inital value. By writing a 16-bit +* value to the low word of this instruction, the driver can change +* the timer value. The current default is either x600 or x800; +* experiments show that the value probably should stay within the +* range of x200 - x1000. +* +* CPUSAVER_BUNDLE_MAX_DWORD - This is the location of the instruction +* that sets the maximum number of frames that will be bundled. In +* some situations, such as the TCP windowing algorithm, it may be +* better to limit the growth of the bundle size than let it go as +* high as it can, because that could cause too much added latency. +* The default is six, because this is the number of packets in the +* default TCP window size. A value of 1 would make CPUSaver indicate +* an interrupt for every frame received. If you do not want to put +* a limit on the bundle size, set this value to xFFFF. +* +* CPUSAVER_MIN_SIZE_DWORD - This is the location of the instruction +* that contains a bit-mask describing the minimum size frame that +* will be bundled. The default masks the lower 7 bits, which means +* that any frame less than 128 bytes in length will not be bundled, +* but will instead immediately generate an interrupt. This does +* not affect the current bundle in any way. Any frame that is 128 +* bytes or large will be bundled normally. This feature is meant +* to provide immediate indication of ACK frames in a TCP environment. +* Customers were seeing poor performance when a machine with CPUSaver +* enabled was sending but not receiving. The delay introduced when +* the ACKs were received was enough to reduce total throughput, because +* the sender would sit idle until the ACK was finally seen. +* +* The current default is 0xFF80, which masks out the lower 7 bits. +* This means that any frame which is x7F (127) bytes or smaller +* will cause an immediate interrupt.

This is + * probably the worst PCI ethernet controller ever made, with the possible + * exception of the FEAST chip made by SMC. The 8139 supports bus-master + * DMA, but it has a terrible interface that nullifies any performance + * gains that bus-master DMA usually offers. + * + * For transmission, the chip offers a series of four TX descriptor + * registers. Each transmit frame must be in a contiguous buffer, aligned + * on a longword (32-bit) boundary. This means we almost always have to + * do mbuf copies in order to transmit a frame, except in the unlikely + * case where a) the packet fits into a single mbuf, and b) the packet + * is 32-bit aligned within the mbuf's data area. The presence of only + * four descriptor registers means that we can never have more than four + * packets queued for transmission at any one time. + * + * Reception is not much better. The driver has to allocate a single large + * buffer area (up to 64K in size) into which the chip will DMA received + * frames. Because we don't know where within this region received packets + * will begin or end, we have no choice but to copy data from the buffer + * area into mbufs in order to pass the packets up to the higher protocol + * levels. + * + * It's impossible given this rotten design to really achieve decent + * performance at 100Mbps, unless you happen to have a 400Mhz PII or + * some equally overmuscled CPU to drive it. + * + * On the bright side, the 8139 does have a built-in PHY, although + * rather than using an MDIO serial interface like most other NICs, the + * PHY registers are directly accessible through the 8139's register + * space. The 8139 supports autonegotiation, as well as a 64-bit multicast + * filter. + * + * The 8129 chip is an older version of the 8139 that uses an external PHY + * chip. The 8129 has a serial MDIO interface for accessing the MII where + * the 8139 lets you directly access the on-board PHY registers.
