Subject: [RFC 11/12] rpmsg: increase buffer size and reduce buffer number
Date: Fri, 29 May 2020 09:37:21 +0200 [thread overview]
Message-ID: <20200529073722.8184-12-guennadi.liakhovetski@linux.intel.com> (raw)
In-Reply-To: <20200529073722.8184-1-guennadi.liakhovetski@linux.intel.com>
It is hard to imagine use-cases where 512 buffers would really be
needed, whereas 512 bytes per buffer might be too little. Change this
to use 16 16KiB buffers instead.
