mainlining shenanigans
When monitoring the GPU with i915 perf, reports are tagged with a hw id. Gem context creation tracepoints already have a hw_id field, unfortunately you only get this correlation between a process id and a hw context id once when the context is created. It doesn't help if you started monitoring after the process was initialized or if the drm fd was transfered from one process to another. This change adds the hw_id field to gem requests, so that correlation can also be done on submission. v2: Place hw_id at the end of the tracepoint to not disrupt too much existing tools (Chris) v3: Reorder hw_id field again (Chris) v4: Add missing hw_id to i915_gem_request_wait_begin tracepoint (Chris) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20171218151959.14073-3-lionel.g.landwerlin@intel.com |

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.
