coresight: moving to new "hwtracing" directory

2015-04-03T14:17:04Z

Keeping drivers related to HW tracing on ARM, i.e coresight, under "drivers/coresight" doesn't make sense when other architectures start rolling out technologies of the same nature. As such creating a new "drivers/hwtracing" directory where all drivers of the same kind can reside, reducing namespace pollution under "drivers/".

coresight-tmc: Adding a status interface to sysfs

2015-04-03T14:17:04Z

Knowing the state of various control register is always useful for degging and tuning. As such add an entry in sysfs that expose to userspace the most important registers. Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight: adding the LINKSINK block as a sink type

2015-04-03T14:17:03Z

>From the TMC TRM, the ETF can be configured as buffer mode, so ETF can be a sink type. Signed-off-by: Xia Kaixu Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight: Adding coresight support for arm64 architecture

2015-04-03T14:17:03Z

Most CoreSight blocks are 64-bit ready. As such move configuration entries from "arch/arm/Kconfig.config" to the driver's subdirectory and source the newly created Kconfig from architecture specific Kconfig.debug files.

coresight: fixing compilation warnings picked up by 64bit compiler

2015-04-03T14:17:03Z

Compiling coresight drivers with a 64-bit compiler highlights a couple of formatting issues, which are fixed by this patch. Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight: making cpu index lookup arm64 compliant

2015-04-03T14:17:03Z

Function "get_logical_index()" is not available on arm64. Instead of adding the function simply using "of_get_cpu_node()" and comparing the return value with cpu handles yields the same result. Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight-replicator: constify of_device_id array

2015-03-26T22:22:22Z

of_device_id is always used as const. (See driver.of_match_table and open firmware functions) Signed-off-by: Fabian Frederick Signed-off-by: Greg Kroah-Hartman

coresight: fix function etm_writel_cp14() parameter order

2015-02-04T18:42:55Z

Function etm_writel_cp14() takes an offset and a value rather than the other way around, something this patch is correcting. The semantic remains the same since it is only a function stub. Signed-off-by: Kaixu Xia Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight-etm: remove check for unknown Kconfig macro

2015-02-04T18:42:55Z

The CoreSight ETM/PTM driver contains a check for a CONFIG_CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE macro. But there's no related Kconfig symbol CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE. Remove that check and the single line of code it hides. Signed-off-by: Paul Bolle Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman

coresight: fixing CPU hwid lookup in device tree

2015-02-04T18:42:55Z

Some DT specification will represent CPU nodes with address cells greater than one, making the current code fail. Using the proper retrieval helper function ensure the correct hwid for CPUs is read properly with different address cell size. Signed-off-by: Mathieu Poirier Signed-off-by: Greg Kroah-Hartman
