| * | coresight-stm: support mmapping channel regions with mmio_addr | Chunyan Zhang | 2016-08-31 | 1 | -0/+22 |
| | | | | | | | | | | | | | | | CoreSight STM device allows direct mapping of the channel regions to userspace for zero-copy writing. To support this ability, the STM framework has provided a hook 'mmio_addr', this patch just implemented this hook for CoreSight STM. This patch also added an item into 'channel_space' to save the physical base address of channel region which mmap operation needs to know.

| * | coresight: stm: adding driver for CoreSight STM component | Pratik Patel | 2016-05-03 | 1 | -0/+920 |
| This driver adds support for the STM CoreSight IP block, allowing any system compoment (HW or SW) to log and aggregate messages via a single entity. The CoreSight STM exposes an application defined number of channels called stimulus port. Configuration is done using entries in sysfs and channels made available to userspace via configfs.
