From 0b23e2a6ed5cb1196dae7d34c5910193d86244a9 Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Mon, 14 Oct 2019 11:36:02 -0700 Subject: drm/i915/huc: improve documentation Better explain the usage of the microcontroller and what i915 is responsible of. While at it, fix the documentation for the auth function, which doesn't do any pinning anymore. v2: add a comment on HuC being optional and descrive how HuC accesses memory (Martin) v3: add extra newline for better text organization (Martin) Signed-off-by: Daniele Ceraolo Spurio Cc: Michal Wajdeczko Cc: Martin Peres Acked-by: Anna Karas Reviewed-by: Martin Peres Link: https://patchwork.freedesktop.org/patch/msgid/20191014183602.3643-3-daniele.ceraolospurio@intel.com --- drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c | 15 --------------- 1 file changed, 15 deletions(-) (limited to 'drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c') diff --git a/drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c b/drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c index 74602487ed67..d654340d4d03 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c +++ b/drivers/gpu/drm/i915/gt/uc/intel_huc_fw.c @@ -7,21 +7,6 @@ #include "intel_huc_fw.h" #include "i915_drv.h" -/** - * DOC: HuC Firmware - * - * Motivation: - * GEN9 introduces a new dedicated firmware for usage in media HEVC (High - * Efficiency Video Coding) operations.
