linux.git/include/soc/fsl/bman.h, branch v5.0 Linux kernel source tree soc: fsl: qbman: add APIs to retrieve the probing status 2018-09-27T20:43:35+00:00 Laurentiu Tudor laurentiu.tudor@nxp.com 2018-09-26T13:22:30+00:00 853dc104e6a43cba9a7a87542bc6d8e3b74f0bc9 Add a couple of new APIs to check the probing status of qman and bman: 'int bman_is_probed()' and 'int qman_is_probed()'. They return the following values. * 1 if qman/bman were probed correctly * 0 if qman/bman were not yet probed * -1 if probing of qman/bman failed Drivers that use qman/bman driver services are required to use these APIs before calling any functions exported by qman or bman drivers or otherwise they will crash the kernel. The APIs will be used in the following couple of qbman portal patches and later in the series in the dpaa1 ethernet driver.

soc/fsl: Introduce DPAA 1.x BMan device driver 2016-09-25T07:38:58+00:00 Claudiu Manoil claudiu.manoil@nxp.com 2016-09-22T15:04:08+00:00 1f9c0a77278bc9ec7df14bbd799fccfabff1010a This driver enables the Freescale DPAA 1.x Buffer Manager block. BMan is a hardware accelerator that manages buffer pools. It allows CPUs and other accelerators connected to the SoC datapath to acquire and release buffers during data processing.
