Subject: [PATCH 0/2] Add DMA handle implementation
Date: Mon, 29 Nov 2021 10:58:38 +0530 [thread overview]
Message-ID: <1638163720-23123-1-git-send-email-jeyr@codeaurora.org> (raw)
DMA handle is passed in an RPC call. When call reaches DSP,the fd is
added to DSP user process fd list. To unmap any DMA handle, DSP request
for unmap of fd and add it to fdlist which is then freed by driver when
call is returned from DSP.
