From: Oscar Mateo <oscar.mateo@xxxxxxxxx> For a description of this patchset, please check the previous cover letters: [1] and [2]. The main difference with v2 is in how we get to the point of context submission: this time around, instead of massaging the legacy ringbuffer submission functions (mostly located in intel_ringebuffer.c), I have effectively created a separate path for Execlists submission in intel_lrc.c (even though everybody knows you shouldn't mess with split timelines). The alternative path is mostly a clone of the previous, but the idea is that it will differ significantly in the (so in exchange for duplicated code, we gain the ability to perform big changes without breaking legacy hardware support). This change was a suggestion by Daniel Vetter [3]. I know many patches here will be very controversial, so I would appreciate early feedback in the direction this effort is taking. The previous IGT test [4] still applies.
