I need to get the network controller split from the audio controller, but with downstream they appear in the same group as before and with downstream,multifunction the show up in group 12 (11 before) demesg shows: Warning: PCIe ACS overrides enabled; This may allow non-IOMMU protected pee...
Maybe the group is split but it still does not work. Just test with VirtIO network first and see if it is good enough.leesteken Distinguished Member Proxmox Subscriber May 31, 2020 6,834 1,993 228 May 31, 2024 #8 Be aware that the network device is the connection with the out...
这里的结构其实很类似我们的mmu的页表了,在arm smmu v3 我们第一层的目录desc的目录结够,大小采用8(STRTAB_SPLIT)位,也就是stream id的高8位,stream id剩下的低位全部用来寻址第二层真正的ste entry; 介绍完了 smmu 中管理设备的ste的表的两种结构后,我们来看看这个ste表的具体结构是啥,里面有啥奥秘呢: 如...

probe_iommu_group()函数为每个系统 I/O 设备执行 IOMMU 探测,该函数定义 (位于drivers/iommu/iommu.c文件中) 如下: staticstructdev_iommu*dev_iommu_get(structdevice*dev) { structdev_iommu*param = dev->iommu; if(param) returnparam; param =kzalloc(sizeof(*param), GFP_KERNEL); ...
