Hello Xen Experts
I am trying to port a linux application or rather a user mode linux driver (not
built into the kernel) to Xen capable linux. This will be running in Dom0. This
user mode driver used the linux pigphysarea patch to allocate large (over 1Gig)
physically contiguous memory.
I have two questions:
1. Is the bigphysarea patch supported on Xen capable linux? If not what is the
maximum physically contiguous memory Xen provides.
2. If I were to run my application in DomU instead of Dom0, can the bigphysarea
patch be used then.
Thanks in advance.
Kashmira
