The only usage outside the intel_lrc.c file is in the ringbuffer init, but the irq mask calculated there is then overwritten for all engines that have a non-zero shift, so we can drop it. This change is not aimed at code saving but at removing from intel_engines information that does not apply to all gens that have the engine. When checking without the temporary WARN_ON, code size is basically unchanged. v2: make the irq_shifts array static const v3: rebase, move irq_shifts array to logical_ring_default_irqs v4: move array inside the if and use u8 for it (Chris) Suggested-by: Michel Thierry <michel.thierry@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Reviewed-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/20180314182653.26981-4-daniele.ceraolospurio@intel.com
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
