From: Michal Wajdeczko Date: Tue, 17 Oct 2017 09:44:49 +0000 (+0000) Subject: drm/i915/uc: Add pretty printer for uc firmware X-Git-Tag: v4.19~298^2~46^2~1312 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=56ffc7427c2b0b27d732a15e062f0c7cdf62c173;p=platform%2Fkernel%2Flinux-rpi3.git drm/i915/uc: Add pretty printer for uc firmware Debugfs for GuC and HuC load info have similar common part. Move and update dump of uc_fw to separate helper for reuse.
