[PATCH 03/13] arm/xen: Use xlated_setup_gnttab_pages to setup grant table

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

Use xlated_setup_gnttab_pages to setup grant table. Then it doesn't rely
on DT or ACPI to pass the start address and size of grant table.
