devicetree,xen: add xen,shared-memory binding

2018-12-10T21:35:51+00:00

Introduce a device tree binding for Xen reserved-memory regions. They
are used to share memory across VMs from the VM config files. (See
static_shm config option.)

treewide: correct "differenciate" and "instanciate" typos

2018-08-24T01:48:43+00:00

Also add these typos to spelling.txt so checkpatch.pl will look for them.

dt-bindings: introduce Command DB for QCOM SoCs

2018-05-23T04:28:54+00:00

Command DB provides information on shared resources like clocks,
regulators etc., probed at boot by the remote subsytem and made
available in shared memory.

dt-binding: soc: qcom: Add binding for rmtfs memory

2017-10-22T10:06:34+00:00

This adds the binding for describing shared memory used to exchange file
system blocks between the RMTFS client and service. A client for this is
generally found in the modem firmware and is used for accessing
persistent storage for things such as radio calibration.

drivers: dma-coherent: Introduce default DMA pool

2017-06-28T13:55:03+00:00

This patch introduces default coherent DMA pool similar to default CMA
area concept. To keep other users safe code kept under CONFIG_ARM.

ramoops: Split ftrace buffer space into per-CPU zones

2016-11-16T00:34:26+00:00

If the RAMOOPS_FLAG_FTRACE_PER_CPU flag is passed to ramoops pdata, split
the ftrace space into multiple zones depending on the number of CPUs.

This speeds up the performance of function tracing by about 280% in my
tests as we avoid the locking. The trade off being lesser space available
per CPU. Let the ramoops user decide which option they want based on pdata
flag.

ramoops: use DT reserved-memory bindings

2016-08-05T18:21:36+00:00

Instead of a ramoops-specific node, use a child node of /reserved-memory.
This requires that of_platform_device_create() be explicitly called
for the node, though, since "/reserved-memory" does not have its own
"compatible" property.

of: document bindings for reserved-memory nodes

2014-03-04T08:44:23+00:00

Reserved memory nodes allow for the reservation of static (fixed
address) regions, or dynamically allocated regions for a specific
purpose.
