Subject: [PATCH v3 2/9] powerpc/vas: Define VAS_TX_WIN_OPEN ioctl API
Date: Fri, 06 Mar 2020 16:32:59 -0800	[thread overview]
Message-ID: <1583541179.9256.32.camel@hbabu-laptop> (raw)
In-Reply-To: <1583540877.9256.24.camel@hbabu-laptop>


Define the VAS_TX_WIN_OPEN ioctl interface for NX GZIP access
from user space. This interface is used to open GZIP send window and
mmap region which can be used by userspace to send requests to NX
directly with copy/paste instructions.
