Subject: [PATCH] hw/arm/smmuv3: Store the PASID table GPA in the translation
|
||
|
|
config
|
||
|
|
|
||
|
|
For VFIO integration we will need to pass the Context Descriptor (CD)
|
||
|
|
table GPA to the host. The CD table is also referred to as the PASID
|
||
|
|
table. Its GPA corresponds to the s1ctrptr field of the Stream Table
|
||
|
|
Entry. So let's decode and store it in the configuration structure.
