* docs: Add automatic cross-reference for C typesNícolas F. R. A. Prado2020-09-031-13/+24
| | | | | | | | | | | | | | | | In order to cross-reference C types in the documentation, Sphinx requires the syntax :c:type:`type_name`, or even :c:type:`struct type_name <type_name>` in order to have the link text different from the target text. Extend automarkup to enable automatic cross-reference of C types by matching any "struct|union|enum|typedef type_name" expression. This makes the documentation's plain text cleaner and adds cross-reference to types without any additional effort by the author. Signed-off-by: Nícolas F. R. A.

* Documentation: clarify driver licensing rulesDave Hansen2020-08-311-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Greg has challenged some recent driver submitters on their license choices. He was correct to do so, as the choices in these instances did not always advance the aims of the submitters. But, this left submitters (and the folks who help them pick licenses) a bit confused. They have read things like Documentation/process/license-rules.rst which says: individual source files can have a different license which is required to be compatible with the GPL-2.0 and Documentation/process/submitting-drivers.rst: We don't insist on any kind of exclusive GPL licensing, and if you wish ... you may well wish to release under multiple licenses. As written, these appear a _bit_ more laissez faire than we've been in practice lately. It sounds like we at least expect submitters to make a well-reasoned license choice and to explain their rationale. It does not appear that we blindly accept anything that is simply GPLv2-compatible. Drivers appear to be the most acute source of misunderstanding, so fix the driver documentation first. Update it to clarify expectations.

| | | | | | | | | | | | | | | | | | | | | Based on a vote at the LLVM BoF at Plumbers 2020, we decided to start small, supporting just one formal upstream release of LLVM for now. We can probably widen the support window of supported versions over time. Also, note that LLVM's release process is different than GCC's. GCC tends to have 1 major release per year while releasing minor updates to the past 3 major versions. LLVM tends to support one major release and one minor release every six months.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another wack-a-mole pass of killing off unnecessary 'allOf + $ref' usage. json-schema versions draft7 and earlier have a weird behavior in that any keywords combined with a '$ref' are ignored (silently). The correct form was to put a '$ref' under an 'allOf'. This behavior is now changed in the 2019-09 json-schema spec and '$ref' can be mixed with other keywords. The json-schema library doesn't yet support this, but the tooling now does a fixup for this and either way works. This has been a constant source of review comments, so let's change this treewide so everyone copies the simpler syntax. Signed-off-by: Rob Herring <robh@kernel.org>

Among other things, this allows utilization clamps to be taken into account, at least to a certain extent, when intel_pstate is in use and makes it more likely that sufficient capacity for deadline tasks will be provided. After this change, the resulting behavior of an HWP system with intel_pstate in the passive mode should be close to the behavior of the analogous non-HWP system with intel_pstate in the passive mode, except that the HWP algorithm is generally allowed to make the CPU run at a frequency above the floor P-state set by intel_pstate in the entire available range of P-states, while without HWP a CPU can run in a P-state above the requested one if the latter falls into the range of turbo P-states (referred to as the turbo range) or if the P-states of all CPUs in one package are coordinated with each other at the hardware level. [Note that in principle the HWP floor may not be taken into account by the processor if it falls into the turbo range, in which case the processor has a license to choose any P-state, either below or above the HWP floor, just like a non-HWP processor in the case when the target P-state falls into the turbo range.] With this change applied, intel_pstate in the passive mode assumes complete control over the HWP request MSR and concurrent changes of that MSR (eg. via the direct MSR access interface) are overridden by it.
