Intel PT: - Support "ptwrite" instructio, a way to stuff 32 or 64 bit values into the Intel PT trace (Adrian Hunter) - Support power events in Intel PT to report changes to C-state (Adrian Hunter) - Synthesize Intel PT events as PERF_RECORD_SAMPLE records with a perf_event_attr.type (PERF_TYPE_SYNTH) just after the range used by the kernel, i.e. right after what is allocated for PMUs, at INT_MAX + 1U, attr.config will have the identification for the synthesized event and the PERF_SAMPLE_RAW payload will have its fields (Adrian Hunter) Infrastructure: - Remove warning() and error(), using instead pr_warning() and pr_error(), consolidating error reporting (Arnaldo Carvalho de Melo) - Add platform dependency to 'perf test 15' (Thomas Richter) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJZVsurAAoJENZQFvNTUqpAnYYP/i44/Y99vfN751fuTlJYci2g u1VVRsd0GC8OnFIZKRzFumAd+IXRUXiLp25nP36yvsXNOMHGU1O/SQmRRHOC6zTY ffPmnlHeUT8LOVX82GiiG6E6rzE2KHuAbgILvzswelPoyT6/91mysoZMu2xHpy3f sLUtjN7gAZqy6nMNTiGgItUDyFIAl4c2iQf5v8YkxfM0UxekXt/XIj2Zn5uUXTIW q9B0po9/MneI+7Fqtj3YTN7owY0YhXmynKHzE7CseNyGFFbtIzoTLW3qgtz+Ld3M ip0QcsRiV6hbgEkPsi6nwOAF1EABlsHb4QHwFifVqzWCPwqeLmI3rd7FsONDNcCZ TVoHfm1wlgqtQw6KVQodIrTKCq7DOpjTIzk6AX980vJ8yp2KtWf2DB0AqwpJ/7R2 2nqTsLm9iWbPOTA0mp/7au/WbNDcgL9jv2yqU8/UGBg92tVlVN5IiAVVpnsdBJgi VjEeUdqbvs9aw//+L1uN0N7Y22zqpQAm/eomd9wwXzDHCeWjIcrIR4tDA5i22waH 4XFJLgJhfbTZsSGonpQ+7GVPzFru3rz56wAM4UbD3BRtVCj+EMPu0/mb9u3URgjp 1iJdOm7WY/XH7AYV5dXnZyR+o4VDHwuziw5yxvoR3RNpARxAjVFGzXfq6Q5DbHPS mycD8rcoQp+3IeyA/IEN =tvJF -----END PGP SIGNATURE----- Merge tag 'perf-core-for-mingo-4.13-20170630' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo: Intel PT enhancements: - Support "ptwrite" instruction, a way to stuff 32 or 64 bit values into the Intel PT trace (Adrian Hunter) - Support power events in Intel PT to report changes to C-state (Adrian Hunter) - Synthesize Intel PT events as PERF_RECORD_SAMPLE records with a perf_event_attr.type (PERF_TYPE_SYNTH) just after the range used by the kernel, i.e. right after what is allocated for PMUs, at INT_MAX + 1U, attr.config will have the identification for the synthesized event and the PERF_SAMPLE_RAW payload will have its fields (Adrian Hunter) Infrastructure changes: - Remove warning() and error(), using instead pr_warning() and pr_error(), consolidating error reporting (Arnaldo Carvalho de Melo) - Add platform dependency to 'perf test 15' (Thomas Richter) Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Ingo Molnar <mingo@kernel.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
