FAQ
1. iStoreOS直通后重启，无线网卡变为未激活？
Defect Description
首次直通正常，能识别网卡
重启后，设备未激活
Solution
-
需要关机PVE => 拔掉网卡 => 启动PVE => 关机PVE => 插入网卡 => 启动PVE -
关机PVE，完全断电后重启（目的是使无线网卡断电，怀疑被占用）
-
改用OpenWrt
OpenWrt
OpenWRT-PVE-AP-MT7922: guide to run OpenWRT on PVE with Access Point through m.2 wifi module MT7922
Setting up the OpenWrt disk
gunzip -k /mnt/pve/hdd/template/iso/openwrt-23.05.3-x86-64-generic-ext4-combined-efi.img.gz

Install wireless LAN card driver and firmware
opkg update
opkg install kmod-iwlwifi iwlwifi-firmware-ax210
opkg install kmod-mt7921e
cd /lib/firmware/mediatek
wget https://github.com/openwrt/mt76/raw/master/firmware/WIFI_MT7922_patch_mcu_1_1_hdr.bin

FAQ
1. OpenWrt直通后重启，无线网卡is not active
首次直通
重启后
Solution
-
restart一次设备即可
-
设置开机脚本
System => Startup => Local startup
uci set wireless.radio0.disabled='1'
uci set wireless.default_radio0.disabled='1'
uci commit wireless
wifi reload
sleep 5
uci set wireless.radio0.disabled='0'
uci set wireless.default_radio0.disabled='0'
uci commit wireless

FAQ
1. No IOMMU detected
Proxmox VE(PVE)开启IOMMU功能实现硬件直通及直通错误解决_no iommu detected, please activate it.see document-CSDN博客
Solution
开启IOMMU，参考上文
2. 启动直通VM后，PVE文件系统失联
Defect Description
Reason
m2固态系统盘与无线网卡处在同一IOMMU组，被连带直通导致文件系统失联
Troubleshoot
查询IOMMU组
for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done;

【折腾踩坑记录】关于EXSI的网卡SR-IOV，以及X520DA2/SR2有什么区别的这档事。 - 哔哩哔哩
Solution
强制IOMMU分组
方法一. BIOS开启ACS(Access Control Services)
AMD CBS => NBIO Common Options => Enable AER Cap => ACS Enable
（华擎主板开启AER Cap后才会出现ACS）
方法二. ACS补丁
# /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... pcie_acs_override=downstream"
3. 启动直通VM后，WebGUI失联，物理机终端有响应
Reason
开启ACS后，有线、无线网卡仍在一组，有线网卡被连带直通导致网络失联
Solution
# /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... pcie_acs_override=multifunction"

2. 连接无线热点
