From: Mathieu Poirier <mathieu.poirier@linaro.org> To: linux-arm-kernel@lists.infradead.org, Suzuki.Poulose@arm.com Cc: linux-kernel@vger.kernel.org Subject: [PATCH V2 00/15] coresight: tmc: make driver usable by Perf Date: Tue, 12 Apr 2016 11:54:37 -0600 [thread overview] Message-ID: <1460483692-25061-1-git-send-email-mathieu.poirier@linaro.org> (raw) This patchset makes the TMC driver usable from Perf by way of the recently added AUX area functionality. The first 12 patches remodel the driver so that the functionality is compartmented enough to be used as building blocks when interfacing with the Perf subsystem. Patch 13 and 14 implement the AUX area API, taking heavily on the existing ETB10 implementation. Finally patch 15 allows the TMC to be used as a link rather than a sink, something that is required when dealing with an ETF component. Best regards, Mathieu Changes for V2: - Renamed functions tmc_read_prepare/unprepare_etf() to tmc_read_prepare/unprepare_etb(). - Consolidated return points in functions tmc_enable_etf/etr_sink(). - Re-wrote allocation schemed in functions tmc_enable_etf/etr_sink(). - Fixed description typos in patch 7/15. - Fixed problem with linksink devices when disabling a path in patch 15/15.
