This is the minimal conversion to derive struct i915_gem_request from dma-buf fences. They are still only used privately (i.e. the requests are not attached to the dma-buf or any reservation object so not exposed to any other driver or userspace) and so we defer the issue of RCU access to the request until later - until we have annotations over own access to the request so that we can catch RCU issues.
This series just looks at the issues surrounding using requests as fences, plus a bonus patch aimed at BAT/bsw. -Chris _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/intel-gfx
