Description:
5+
Process Address Space ID (PASID) assigned by IOMMU driver to
6+
the device for use with Shared Virtual Addressing (SVA).
7+
8+
This read-only attribute exposes the PASID (A 20-bit identifier
9+
used in PCIe Address Translation Services and iommu table walks)
10+
allocated by the IOMMU driver during sva device binding.
11+
12+
User-space UIO applications must read this attribute to obtain
13+
the PASID and program it into the device's configuration registers.
14+
This enables the device to perform DMA using user-space virtual
15+
address, with address translation handled by IOMMU.
16+
17+
UIO User-space applications must:
18+
- Opening device and Mapping the device's register space via /dev/uioX
19+
(This triggers the IOMMU driver to allocate the PASID)
20+
- Reading the PASID from sysfs
21+
- Writing the PASID to a device-specific register (with example offset)
22+
The code may be like:
23+
24+
map = mmap(..., "/dev/uio0", ...);
25+
26+
f = fopen("/sys/.../pasid", "r");
27+
fscanf(f, "%d", &pasid);
28+
29+
map[REG_PASID_OFFSET] = pasid;
