关于DM8168 PCIE转千兆以太网的问题

alvin lu
Expert 1510 points


我用的是官方的EVM板，我的SW5的设置是off ,也就是拨码开关都设置为靠近PCIE插座。在这种设置下，当我插了PCIE网卡（x1），上电串口竟然无反应，此PCIE网卡我已经在PC机上测试过了，可以使用。以下是我不插PCIE网卡的时候串口打印信息。

    目前的情况是我的SW5的设置是off ,也就是拨码开关都设置为靠近PCIE插座。在这种设置下，当我插了PCIE网卡（x1），上电串口无反应，我的系统起不来，按照E2E上老外给的说法，当我连接PCIE网卡设备的时候，SW5应该就是这样设置的。

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/106374.aspx

    OFF is towards the PCIe slot, that is farther to R195. The switch bank has written "ON" (small font) on it on the opposite side.

    我的PCIE网卡在PC机上测试过的，可以用。

    你好，

       由于DM8168不支持PCIE设备的热插拔，而设置SW5为OFF的目的在于，保证EP设备优先于RC设备启动，使用EP设备的复位信号通过SLOT的A11来复位RC设备。

        当你的网卡插PCIE slot的时候，你看一下，是否是A11脚的电平不正常，这样导致了DM8168一直处于复位状态，无法正常启动。

        同时查一下，你的PCIE X1网卡是否用到了B10 3.3VAUX这个pin脚供电，在EVM上，这个脚是悬空的。

    我给B11飞了一个3.3V供电，现在PCIE网卡能识别到了，也驱动起来了，可以给ethX来配置ip，但是ping不通，暂时不清楚原因，驱动我用的是官方下载的驱动。明天打算用官方推荐的BCM5751测试一下。

    同时问一个问题，板子上的PCIE2X是不是可以扩两路千兆以太网？

    不行，只能支持一路PCIE2X或者一路PCIE1X。

    从log信息来看，PCIe 网卡BCM5751已经找到，并且网络link已经建立。PCIe应该没有什么问题，问题应该在网络驱动和使用方面。

    网络连接使用dhcp还是静态IP？从log信息看dhcp应该不能工作。你的网络是怎么配置的？

    我工作的时候是设置的静态的IP。 dhcp其实是可以使用的，只是我把udhcpc这个命令去掉了，所以log里面有这么一句/bin/sh: udhcpc: not found。

    我也还疑过是驱动的问题，所以我另外尝试了RTL8111C和INTEL82574这两款PCIE 网卡，情况基本是一样的,我觉得不大可能是三家公司的驱动同时有问题。

    TI的原理图上，wake脚没有接，我不清楚这个会不会带来大的影响？我看了几个其他平台的PCIE包括笔记本的，都是接了的。

    包括SW5的设置，无论是on还是off都尝试过了。

    包括这一段

    Controlling PERSTn Using I2C Writes
    Note that this description assumes the above mentioned EVM modification is already done.
    As mentioned earlier, the PERSTn line on the A11 pin of PCIe slot on the EVM can be toggled by controlling I2C0
    writes to IOEXPANDER port 14. This corresponds to performing i2c writes to address 0x20 bit 12.
    • Setting this bit to 1 makes PERSTn pin high (EP reset de-asserted).
    • Setting this bit to 0 means PERSTn pin low (reset asserted) and EP will remain in reset.
    As an example, following commands at U-Boot prompt will toggle reset to EP during boot:
    TI8168_EVM# i2c mw 0x20 ff ef <--- Set bit 12 to 0 to assert PERSTn (default is 1, de-asserted)
    TI8168_EVM# i2c mw 0x20 ff ff <--- Set bit 12 to 1 to de-assert PERSTn and get EP out of reset
    The above sequence can be set as part of U-Boot's bootcmd as shown below to ensure it is executed on every reset
    and before booting the kernel (assuming kernel is flashed in NAND @0x280000 offset):
    TI8168_EVM# setenv bootcmd 'i2c mw 0x20 ff ef; i2c mw 0x20 ff ff; nand read.i 81000000 280000 500000; bootm 81000000'
    TI8168_EVM# saveenv
    This sequence can also be added to Kernel board file to perform similar i2c writes at boot up.

    能尝试的都尝试了。

    Dong Yang 谢谢你对这个帖子的关注。

    不知道TI能否在DM8168平台上对

    请问你使用的NetXtreme BCM5751 Gigabit Ethernet PCI Express 是GEN1 speeds with x1 link，并且版本是(rev 01)么？

    下面是TI使用该网卡时候的测试数据。

    这个rev 01 好像片子上看不出来啊，是这样的，我一共买了3款BCM5751的网卡，其中一款是博通原装的，另外两个是国内厂家生产的，目前的一个结果都是一样的，设备可以识别到，就是ping不通，我也好郁闷。

    这是我使用rtl8111c PCIE网卡的信息。依然是ping不通。

    从你的打印信息上看，RTL8111C并没有在PCI Scan中扫描到，你用的是TI的EVM么？请在PCI SCAN的时候把LTSSM寄存器打印一下。

    Louis 你好，

    RTL8111C已经初始化并加载成功，你可以看到这句01:00.0 Class 0200: Device 10ec:8168，Kernel driver in use: r8168 .realtek 8111X系列网卡使用的是RTL8168的驱动，所以这里显示是8168，实际上这是我插的RTL8111C。

    系统启动的时候，有这些log：

    从这两句eth%d: RTL8168C/8111C at 0xd708a000, 00:e0:4c:a2:06:a1, IRQ 368

    eth0 Link encap:Ethernet HWaddr 00:E0:4C:A2:06:A1

    MAC地址可以看到，我的eth0的确就是RTL8111C。

    这里我们可以看到，我的eth0就是tg3的节点，也就是我的BCM5751.并且tg3 0000:01:00.0: eth0: Link is up at 100 Mbps, full duplex看到设备已经启动，并且是100M全双工。

    系统启动完成之后。ifconfig -a 看所有eth设备

    其中，eth0 是BMC5751，eth1 eth2是DM8168自带的以太网控制器
    此时我将我的笔记本和DM8168接到同一个工业交换机。并配置DM8168的ip
    eth0      Link encap:Ethernet  HWaddr 00:10:18:0B:3B:76

    以下三句是配置的对于IP，这是不同网段的。
    ifconfig eth0 193.168.100.110
    ifconfig eth1 192.168.1.110
    ifconfig eth2 192.168.10.110
    现在我用PC来ping 对应的DM8168对应的ip
    以下是ping的结果
    root@ubuntu:/usr/ezsdk/board-support/linux-2.6.37-psp04.04.00.01# ping 192.168.1.110
    PING 192.168.1.110 (192.168.1.110) 56(84) bytes of data.

    由以上可知，此时片上eth1 eth2是可用的。BCM5751的eth0是不可用的。
    现在我再从DM8168ping一下PC：
    root@luhao:~# ping 192.168.1.60
    PING 192.168.1.60 (192.168.1.60): 56 data bytes

    PING 193.168.100.60 (193.168.100.60): 56 data bytes
    由以上可知，除eth0之外，都是可ping通的。
    此时，我将eth0的ip设置为与eth1同一个网段，

    此时ip已经变成了192.168.1.125.
    和eth1的192.168.1.110在同一个网段，此时，我用pc来ping一下eth0
    root@ubuntu:/usr/ezsdk/board-support/linux-2.6.37-psp04.04.00.01# ping 192.168.1.125
    PING 192.168.1.125 (192.168.1.125) 56(84) bytes of data.
    64 bytes from 192.168.1.125: icmp_seq=1 ttl=64 time=1.91 ms
    64 bytes from 192.168.1.125: icmp_seq=2 ttl=64 time=1.01 ms
    ^C

    rtt min/avg/max/mdev = 1.015/1.465/1.915/0.450 ms
    由以上可知，此时ping通了。我再尝试从DM8168使用eth0 来ping我的pc
    root@luhao:~# ping 192.168.1.60        
    PING 192.168.1.60 (192.168.1.60): 56 data bytes

    3 packets transmitted, 3 packets received, 0% packet loss
    round-trip min/avg/max = 0.303/0.753/1.424 ms
    看上去是ping通，但是此时，我们并不确定到底是走的eth0还是eth1呢？
    OK。我现在来指定某一个eth来ping我的pc
    root@luhao:~# ping 192.168.1.60 -I eth0
    PING 192.168.1.60 (192.168.1.60): 56 data bytes
    由以上可知，当我指定为eth0的时候，就ping不通了，那么我现在来指定eth1试试。
    root@luhao:~# ping 192.168.1.60 -I eth1
    PING 192.168.1.60 (192.168.1.60): 56 data bytes
    64 bytes from 192.168.1.60: seq=0 ttl=64 time=0.554 ms
    64 bytes from 192.168.1.60: seq=1 ttl=64 time=0.443 ms
    --- 192.168.1.60 ping statistics ---
    2 packets transmitted, 2 packets received, 0% packet loss
    round-trip min/avg/max = 0.443/0.498/0.554 ms
    由以上可知，指定eth1是没问题的。
    此时我再做一个新的实验，我现在拔掉路由器上对应的eth0，也就是插BCM5751的网线。然后再来ping一下eth0和eth1
    结果如下，（当我拔掉eth0网线的时候，串口kog打印出tg3 0000:01:00.0: eth0: Link is down，再一次证明，eth0对应的是TG3，也就是BCM5751)
    root@ubuntu:/usr/ezsdk/board-support/linux-2.6.37-psp04.04.00.01# ping 192.168.1.125

    rtt min/avg/max/mdev = 1.010/1.097/1.248/0.113 ms
    由以上可知。此时在没有插eth0网线的情况下，我主机可以同时ping通eth0和eth1这两个ip。但需要注意一点，此时eth0和eth1是在同一个网段的。那么我此时将eth0的ip改回去，也就说不再和eth1一个网段
    ifconfig eth0 193.168.100.110
    此时我用pc来ping  eth0的ip
    root@ubuntu:/usr/ezsdk/board-support/linux-2.6.37-psp04.04.00.01# ping 193.168.100.110
    PING 193.168.100.110 (193.168.100.110) 56(84) bytes of data.
    ^C
    --- 193.168.100.110 ping statistics ---
    3 packets transmitted, 0 received, 100% packet loss, time 2015ms
    以上可知，此时ping不通。
    从以上实验来看，感觉我的eth0似乎成了eth1的一个路由节点。
    此时，我用命令来路由一下eth0到eth1
    root@luhao:~# route add -net 193.168.100.0 netmask 255.255.255.0 dev eth1
    然后再尝试用pc  ping  eth0
    root@ubuntu:/usr/ezsdk/board-support/linux-2.6.37-psp04.04.00.01# ping 193.168.100.110
    PING 193.168.100.110 (193.168.100.110) 56(84) bytes of data.
    64 bytes from 193.168.100.110: icmp_seq=1 ttl=64 time=4.01 ms
    64 bytes from 193.168.100.110: icmp_seq=2 ttl=64 time=1.06 ms
    ^C
    --- 193.168.100.110 ping statistics ---
    2 packets transmitted, 2 received, 0% packet loss, time 1001ms
    rtt min/avg/max/mdev = 1.062/2.538/4.015/1.477 ms
    以上可知，现在ping通了。
    我再从DM8168ping主机，
    root@luhao:~# ping 193.168.100.60
    PING 193.168.100.60 (193.168.100.60): 56 data bytes
    64 bytes from 193.168.100.60: seq=0 ttl=64 time=7.693 ms
    64 bytes from 193.168.100.60: seq=1 ttl=64 time=0.483 ms
    --- 193.168.100.60 ping statistics ---
    2 packets transmitted, 2 packets received, 0% packet loss
    round-trip min/avg/max = 0.483/4.088/7.693 ms
    也是通的。
    但是，此时需要注意一点，我并没有插eth0对应的网线！
    此时看一下route
    root@luhao:~# route -n
    Kernel IP routing table
    Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
    193.168.100.0   0.0.0.0         255.255.255.0   U     0      0        0 eth1
    193.168.100.0   0.0.0.0         255.255.255.0   U     0      0        0 eth0
    192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
    192.168.10.0    0.0.0.0         255.255.255.0   U     0      0        0 eth2

    以上是针对BCM5751做的实验，我同时也是用RTL8111C做了一样的实验，结果，也是一样的。
    感谢大家花这么多时间耐心读完。

    两个ip都是可以ping通的，但是我从DM8168指定IPping主机的话，eth0是不通的
    root@luhao:~# ping 192.168.1.60 -I eth0

    round-trip min/avg/max = 0.479/0.712/0.945 ms
    从TI的这个手册来看
    TI曾经在DM8168 EVM上基于BCM5751做过PCIE网卡性能测试，且测试的时候禁用了片上双千兆网。
    我也尝试过禁掉片上双网卡，无论是从应用层还是驱动层，但是PCIE网卡都没有起来。
    以上ping通的情况有一个现象需要说明一下，当我eth0对应的网线拔掉，所做的测试结果都是一样的，而当我的eth1网线拔掉的时候，情况是都ping不通。

    问题解决了，谢谢大家这么长时间的关注。

    Since TI81XX RC supports maximum remote read request size (MRRQS) as 256 bytes, ensure that the EP driver/device you are using doesn't set read request size more than this value. If it does, then modify the driver to set read request size to 256 bytes before building it. Ensuring Maximum Read Request size within 256 Byte limit is required even for any intermediate Switch/Bridge devices in the fabric.

    需要改驱动里面read request size，这个每个驱动对应的函数描述不大一样，但是类似，大家可以参考下博通的pcie_set_readrq函数，默认设置的是4096，改成256就行了。

    OK。
