Di915_small_bar.rst39 With error capture we have two new restrictions:
41 1) Error capture is best effort on small BAR systems; if the pages are not
42 CPU accessible, at the time of capture, then the kernel is free to skip
43 trying to capture them.
45 2) On discrete and newer integrated platforms we now reject error capture
47 error capture, when for example something is not currently CPU accessible.
