We only need to acquire a wakeref for ourselves for a few operations, as most either already acquire their own wakeref or imply a wakeref. In particular, it is i915_gem_set_wedged() that needed us to present it with a wakeref, which is incongruous with its "use anywhere" ability. Suggested-by:

We assumed that vm_mmap() would reject an attempt to mmap past the end of the filp (our object), but we were wrong. Applications that tried to use the mmap beyond the end of the object would be greeted by a SIGBUS. After this patch, those applications will be told about the error on creating the mmap, rather than at a random moment on later access. Reported-by:

Split the csc matrix handling to ilk+ and icl+ functions. This keeps the logic clear on what is loaded into which CSC unit on the hardware. We also fix the icl+ code to load the full->limited range conversion matrix into the output CSC rather than the pipe CSC which was used on earlier platforms. And we also turn on the pipe CSC only when the ctm is present. Signed-off-by:

This exactly same approach was already used from gen9 to gen10 and from gen10 to gen11. Let's also use it for gen11+. Let's first assume that we inherit a similar platform and than we apply the differences on top. Different from the previous attempts this will be done this time with coccinelle. We obviously need to exclude some case that is really exclusive for gen11 like PCH, Firmware, and few others.
