There is no reason to consider the setup of Data Stolen Memory fatal on dgfx and non-fatal on integrated. Move the debug and error propagation around so both have the same behavior: non-fatal. Before this change, loading i915 on a system with TGL + DG2 would result in just TGL succeeding the initialization (without stolen). Now loading i915 on the same system with an injected failure in i915_gem_init_stolen(): $ dmesg | grep stolen i915 0000:00:02.0: [drm] Injected failure, disabling use of stolen memory i915 0000:00:02.0: [drm:init_stolen_smem [i915]] Skip stolen region: failed to setup i915 0000:03:00.0: [drm] Injected failure, disabling use of stolen memory i915 0000:03:00.0: [drm:init_stolen_lmem [i915]] Skip stolen region: failed to setup Both GPUs are still available: $ sudo build/tools/lsgpu card1 Intel Dg2 (Gen12) drm:/dev/dri/card1 └─renderD129 drm:/dev/dri/renderD129 card0 Intel Tigerlake (Gen12) drm:/dev/dri/card0 └─renderD128 drm:/dev/dri/renderD128 Reviewed-by: Wayne Boyer <wayne.boyer@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220915-stolen-v2-3-20ff797de047@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.
