From: Michal Wajdeczko Date: Thu, 21 Dec 2017 21:57:34 +0000 (+0000) Subject: drm/i915: Add pretty printer for runtime part of intel_device_info X-Git-Tag: v4.19~298^2~46^2~867 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5fbbe8d4e102352af0349f0d5fe9d567319e0877;p=platform%2Fkernel%2Flinux-rpi.git drm/i915: Add pretty printer for runtime part of intel_device_info During initialization of the runtime part of the intel_device_info we are dumping that part using DRM_DEBUG_DRIVER mechanism. As we already have pretty printer for const part of the info, make similar function for the runtime part and use it separately. v2: add runtime dump to debugfs (Chris) Signed-off-by: Michal Wajdeczko Cc: Chris Wilson Cc: Rodrigo Vivi Cc: Joonas Lahtinen Link: https://patchwork.freedesktop.org/patch/msgid/20171221185334.17396-7-michal.wajdeczko@intel.com Reviewed-by: Chris Wilson Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20171221215735.30314-6-chris@chris-wilson.co.uk --- diff --git a/drivers/gpu/drm/i915/i915_debugfs.c b/drivers/gpu/drm/i915/i915_debugfs.c index 3affcaa..e968aea 100644 --- a/drivers/gpu/drm/i915/i915_debugfs.c +++ b/drivers/gpu/drm/i915/i915_debugfs.c @@ -48,6 +48,7 @@ static int i915_capabilities(struct seq_file *m, void *data) seq_printf(m, "pch: %d\n", INTEL_PCH_TYPE(dev_priv)); intel_device_info_dump_flags(info, &p); + intel_device_info_dump_runtime(info, &p); kernel_param_lock(THIS_MODULE); i915_params_dump(&i915_modparams, &p); diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 06eea8d..5bf4f58 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -1089,6 +1089,11 @@ static int i915_driver_init_hw(struct drm_i915_private *dev_priv) return -ENODEV; intel_device_info_runtime_init(mkwrite_device_info(dev_priv)); + if (drm_debug & DRM_UT_DRIVER) { + struct drm_printer p = drm_debug_printer("i915 device info:"); + + intel_device_info_dump_runtime(&dev_priv->info, &p); + } intel_sanitize_options(dev_priv); diff --git a/drivers/gpu/drm/i915/intel_device_info.c b/drivers/gpu/drm/i915/intel_device_info.c index 8e050b5..d28592e 100644 --- a/drivers/gpu/drm/i915/intel_device_info.c +++ b/drivers/gpu/drm/i915/intel_device_info.c @@ -78,6 +78,32 @@ void intel_device_info_dump_flags(const struct intel_device_info *info, #undef PRINT_FLAG } +static void sseu_dump(const struct sseu_dev_info *sseu, struct drm_printer *p) +{ + drm_printf(p, "slice mask: %04x\n", sseu->slice_mask); + drm_printf(p, "slice total: %u\n", hweight8(sseu->slice_mask)); + drm_printf(p, "subslice total: %u\n", sseu_subslice_total(sseu)); + drm_printf(p, "subslice mask %04x\n", sseu->subslice_mask); + drm_printf(p, "subslice per slice: %u\n", + hweight8(sseu->subslice_mask)); + drm_printf(p, "EU total: %u\n", sseu->eu_total); + drm_printf(p, "EU per subslice: %u\n", sseu->eu_per_subslice); + drm_printf(p, "has slice power gating: %s\n", + yesno(sseu->has_slice_pg)); + drm_printf(p, "has subslice power gating: %s\n", + yesno(sseu->has_subslice_pg)); + drm_printf(p, "has EU power gating: %s\n", yesno(sseu->has_eu_pg)); +} + +void intel_device_info_dump_runtime(const struct intel_device_info *info, + struct drm_printer *p) +{ + sseu_dump(&info->sseu, p); + + drm_printf(p, "CS timestamp frequency: %u kHz\n", + info->cs_timestamp_frequency_khz); +} + void intel_device_info_dump(const struct intel_device_info *info, struct drm_printer *p) { @@ -558,22 +584,4 @@ void intel_device_info_runtime_init(struct intel_device_info *info) /* Initialize command stream timestamp frequency */ info->cs_timestamp_frequency_khz = read_timestamp_frequency(dev_priv); - - DRM_DEBUG_DRIVER("slice mask: %04x\n", info->sseu.slice_mask); - DRM_DEBUG_DRIVER("slice total: %u\n", hweight8(info->sseu.slice_mask)); - DRM_DEBUG_DRIVER("subslice total: %u\n", - sseu_subslice_total(&info->sseu)); - DRM_DEBUG_DRIVER("subslice mask %04x\n", info->sseu.subslice_mask); - DRM_DEBUG_DRIVER("subslice per slice: %u\n", - hweight8(info->sseu.subslice_mask)); - DRM_DEBUG_DRIVER("EU total: %u\n", info->sseu.eu_total); - DRM_DEBUG_DRIVER("EU per subslice: %u\n", info->sseu.eu_per_subslice); - DRM_DEBUG_DRIVER("has slice power gating: %s\n", - info->sseu.has_slice_pg ?
