* perf hists: Move sort__need_collapse into struct perf_hpp_listJiri Olsa2016-05-0511-20/+22
| | | | | | | | | | | | | | | | | Now we have sort dimensions private for struct hists, we need to make dimension booleans hists specific as well. Moving sort__need_collapse into struct perf_hpp_list. Adding hists__has macro to easily access this info perf struct hists object.

* perf tools: Add template for generating rbtree resort classArnaldo Carvalho de Melo2016-05-051-0/+149
| | | | | | | | | | | | | | | | | | | | | | Sometimes we want to sort an existing rbtree by a different key, introduce a template for that, that needs only to be provided the rbtree root and the number of entries in it. To do that a new rbtree will be created with extra space for each entry, where possibly pre-calculated keys will be stored to be used in the resort process and also later, when using the newly sorted rbtree. Please check the following two changesets to see it in use for resorting stats for threads and its syscalls in 'perf trace --summary'.

* perf/arm: Special-case hetereogeneous CPUsMark Rutland2016-05-053-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit: 26657848502b7847 ("perf/core: Verify we have a single perf_hw_context PMU") forcefully prevents multiple PMUs from sharing perf_hw_context, as this generally doesn't make sense. It is a common bug for uncore PMUs to use perf_hw_context rather than perf_invalid_context, which this detects. However, systems exist with heterogeneous CPUs (and hence heterogeneous HW PMUs), for which sharing perf_hw_context is necessary, and possible in some limited cases. To make this work we have to perform some gymnastics, as we did in these commits: 66eb579e66ecfea5 ("perf: allow for PMU-specific event filtering") c904e32a69b7c779 ("arm: perf: filter unschedulable events") To allow those systems to work, we must allow PMUs for heterogeneous CPUs to share perf_hw_context, though we must still disallow sharing otherwise to detect the common misuse of perf_hw_context. This patch adds a new PERF_PMU_CAP_HETEROGENEOUS_CPUS for this, updates the core logic to account for this, and makes use of it in the arm_pmu code that is used for systems with heterogeneous CPUs. Comments are added to make the rationale clear and hopefully avoid accidental abuse.

* perf/core: Introduce address range filteringAlexander Shishkin2016-05-052-16/+705
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many instruction tracing PMUs out there support address range-based filtering, which would, for example, generate trace data only for a given range of instruction addresses, which is useful for tracing individual functions, modules or libraries. Other PMUs may also utilize this functionality to allow filtering to or filtering out code at certain address ranges. This patch introduces the interface for userspace to specify these filters and for the PMU drivers to apply these filters to hardware configuration. The user interface is an ASCII string that is passed via an ioctl() and specifies (in the form of an ASCII string) address ranges within certain object files or within kernel. There is no special treatment for kernel modules yet, but it might be a worthy pursuit. The PMU driver interface basically adds two extra callbacks to the PMU driver structure, one of which validates the filter configuration proposed by the user against what the hardware is actually capable of doing and the other one translates hardware-independent filter configuration into something that can be programmed into the hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When calculate temperature, old code firstly do division and then convert to "millicelsius" unit. This will lose resolution and only can read back temperature with "Celsius" unit. So firstly scale step value to "millicelsius" and then do division, so finally we can increase resolution for temperature value. Also refine the calculation from temperature value to step value.

This can result in a subsequent unrelated process getting an spurious IRQ or an interrupt for a non-existent context. This polls the PSL to ensure that the PSL is clear of IRQs for the detached context, before removing the context from the idr.

This won't leak IRQs as if we allocate the mapping again, the generic code will give the same mapping used last time. Doing this works around a race in the generic code. Masking the interrupt introduces a race which can crash the kernel or result in IRQ that is never EOIed. The lost of EOI results in all subsequent mappings to the same HW IRQ never receiving an interrupt. We've seen this race with cxl test cases which are doing heavy context startup and teardown at the same time as heavy interrupt load. A fix to the generic code is being investigated also.
