The Qualcomm Technologies HIDMA device has been designed to support virtualization technology. The driver has been divided into two to follow the hardware design. 1. HIDMA Management driver 2. HIDMA Channel driver Each HIDMA HW consists of multiple channels. These channels share some set of common parameters. These parameters are initialized by the management driver during power up. Same management driver is used for monitoring the execution of the channels. Management driver can change the performance behavior dynamically such as bandwidth allocation and prioritization in the future. The management driver is executed in host context and is the main management entity for all channels provided by the device. ------------------------ What's new ------------------------ - Fix tabs and spaces here and there. - Cleanup timeout in ISR ------------------------ Git repos ------------------------ QEMU Support https://www.codeaurora.org/cgit/quic/qemu/qemu/log/?h=v2.5.0-sriov ------------------------ History of Changes ------------------------ dma: qcom_hidma: add support for object hierarchy Changes from V15: (https://lkml.org/lkml/2016/3/11/619) * copyright year update dma: qcom_hidma: implement lower level hardware interface Changes from V15: (https://lkml.org/lkml/2016/3/11/617) * remove timeout in interrupt handling * fixed a couple of spaces and tabs dma: qcom_hidma: add debugfs hooks Changes from V15: (https://lkml.org/lkml/2016/3/11/616) * copyright year update Sinan Kaya (3): dmaengine: qcom_hidma: implement lower level hardware interface dmaengine: qcom_hidma: add debugfs hooks dmaengine: qcom_hidma: add support for object hierarchy Documentation/ABI/testing/sysfs-platform-hidma | 9 + drivers/dma/qcom/Makefile | 2 + drivers/dma/qcom/hidma.c | 44 +- drivers/dma/qcom/hidma.h | 22 +- drivers/dma/qcom/hidma_dbg.c | 219 ++++++ drivers/dma/qcom/hidma_ll.c | 900 +++++++++++++++++++++++++ drivers/dma/qcom/hidma_mgmt.c | 113 +++- 7 files changed, 1293 insertions(+), 16 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-hidma create mode 100644 drivers/dma/qcom/hidma_dbg.c create mode 100644 drivers/dma/qcom/hidma_ll.c -- 1.8.2.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
