Memory backed portals can be mapped as normal cacheable/shareable memory which allows the portals to migrate between cores without needing manual cache manipulations by the CPU. The patches add support for the new portal attributes in the fsl-mc bus drivers as well as modifying the QBMan driver to use the new portal read trigger mechanism. Changes since v1: * Support older DPRC command in case of older MC firmware * Fix issue with padding in command Roy Pledge (2): bus: mc-bus: Add support for mapping shareable portals soc: fsl: dpio: Add support for memory backed QBMan portals drivers/bus/fsl-mc/dprc.c | 30 +++++++- drivers/bus/fsl-mc/fsl-mc-bus.c | 15 +++- drivers/bus/fsl-mc/fsl-mc-private.h | 17 ++++- drivers/soc/fsl/dpio/dpio-driver.c | 23 ++++-- drivers/soc/fsl/dpio/qbman-portal.c | 148 ++++++++++++++++++++++++++++++------ drivers/soc/fsl/dpio/qbman-portal.h | 5 ++ 6 files changed, 199 insertions(+), 39 deletions(-) --- 2.7.4
