笔记本是小米 air 12.5 寸，ubuntu20.04.2 可以正常驱动和使用触摸板，但是 freebsd11 安装 xfce 后没法使用

下面是 ubuntu 使用 lshw 输出的笔记本信息

ubuntu

下面是/var/log/dmesg的输出，找到了硬件

下面是的 lspci 输出，驱动使用 intel-lpss

lshw 的输出都没有问题

        *-generic:1
             description: Signal processing controller
             product: Sunrise Point-LP Serial IO I2C Controller #0
             vendor: Intel Corporation

             bus info: pci@0000:00:15.0

             configuration: driver=intel-lpss latency=0
             resources: irq:16 memory:b1132000-b1132fff

但是 freebsd 有问题，下面是 freebsd11 的 /var/run/dmesg.boot 输出，找到了硬件，但是是 unknown card

ig4iic0: <Intel Sunrise Point-LP I2C Controller-0> mem 0xb1132000-0xb1132fff irq 16 at device 21.0 on pci0
ig4iic0: Using MSI
iicbus0: <Philips I2C bus (ACPI-hinted)> on ig4iic0
iicbus0: <unknown card> at addr 0x2c

pciconf 也找到了硬件，但是触摸板就是没法用

ig4iic0@pci0:0:21:0:	class=0x118000 card=0x15011d72 chip=0x9d608086 rev=0x21 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Sunrise Point-LP Serial IO I2C Controller'
    class      = dasp

解决了，坑了老夫好些日子

安装iichid模块：
