From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Andersson Subject: [PATCH 0/5] Qualcomm SMD updates Date: Tue, 12 Dec 2017 15:58:52 -0800 Message-ID: <20171212235857.10432-1-bjorn.andersson@linaro.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Ohad Ben-Cohen , Bjorn Andersson , Jeremy McNicoll , Will Newton Cc: linux-remoteproc@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-msm@vger.kernel.org, Chris Lew List-Id: linux-arm-msm@vger.kernel.org A series of fixes for a few issues reported or seen with SMD. The first two fixes changes the trigger for creating devices for channels found, which should cause the rpm-smd driver to probe on 8909 and 8994 devices. The third patch fixes an issue when multiple callers end up waiting on events. The forth fix moves the check for a closed channel out of the tx-full loop, to fail non-full send requests on a closed channel as well. The last fix improves the handling of concurrent send-requests, allowing concurrent sends, in particular try_send, to progress even though we're sleeping waiting for room in the tx fifo.
