From 34904bd64a6990fd32f04b657f290ecabd47abda Mon Sep 17 00:00:00 2001 From: Daniele Ceraolo Spurio Date: Thu, 26 Mar 2020 11:11:19 -0700 Subject: [PATCH] drm/i915/debugfs: move uC printers and update debugfs file names Move the printers to the respective files for clarity. The guc_load_status debugfs has been squashed in the guc_info one, has having separate ones wasn't very useful. The HuC debugfs has been renamed huc_info to match. v2: keep printing HUC_STATUS2 (Tony), avoid const->non-const container_of (Jani) Suggested-by: Michal Wajdeczko Signed-off-by: Daniele Ceraolo Spurio Cc: Michal Wajdeczko Cc: John Harrison Cc: Matthew Brost Cc: Tony Ye Cc: Jani Nikula Reviewed-by: John Harrison Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20200326181121.16869-5-daniele.ceraolospurio@intel.com --- drivers/gpu/drm/i915/gt/uc/intel_guc.c | 44 ++++++++++ drivers/gpu/drm/i915/gt/uc/intel_guc.h | 2 + drivers/gpu/drm/i915/gt/uc/intel_guc_log.c | 92 ++++++++++++++++++++ drivers/gpu/drm/i915/gt/uc/intel_guc_log.h | 4 + drivers/gpu/drm/i915/gt/uc/intel_huc.c | 29 +++++++ drivers/gpu/drm/i915/gt/uc/intel_huc.h | 2 + drivers/gpu/drm/i915/i915_debugfs.c | 131 ++++------------------------- 7 files changed, 189 insertions(+), 115 deletions(-) diff --git a/drivers/gpu/drm/i915/gt/uc/intel_guc.c b/drivers/gpu/drm/i915/gt/uc/intel_guc.c index 827d750..8616578 100644 --- a/drivers/gpu/drm/i915/gt/uc/intel_guc.c +++ b/drivers/gpu/drm/i915/gt/uc/intel_guc.c @@ -723,3 +723,47 @@ int intel_guc_allocate_and_map_vma(struct intel_guc *guc, u32 size, return 0;
