With gen11 the interrupt registers are shared between 2 engines, with Engine1 instance being upper word and Engine0 instance being lower. Annoyingly gen11 selected the pm interrupts to be in the Engine1 instance. Rectify the situation by shifting the access accordingly, based on gen. v2: comments, warn on overzealous rps_events Bugzilla: https://bugzilla.freedesktop.org/show_bug.cgi?id=108059 Testcase: igt/i915_pm_rps@min-max-config-loaded Cc: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20190410105923.18546-6-mika.kuoppala@linux.intel.com
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
