From 4ddbe87a16d75e8f8cb59722fc385b3469a219c3 Mon Sep 17 00:00:00 2001 From: Michał Winiarski Date: Wed, 25 Oct 2017 22:00:12 +0200 Subject: drm/i915/guc: Add preemption action to GuC firmware interface We're using GuC action to request preemption. However, after requesting preemption we need to wait for GuC to finish its own post-processing before we start submitting our requests. Firmware is using shared context to report its status. Let's update GuC firmware interface with those new definitions. v2: Drop unused INTEL_GUC_PREEMPT_OPTION_IMMEDIATE Signed-off-by: Michał Winiarski Cc: Jeff McGee Cc: Michal Wajdeczko Cc: Oscar Mateo Reviewed-by: Jeff McGee Signed-off-by: Chris Wilson Link: https://patchwork.freedesktop.org/patch/msgid/20171025200020.16636-5-michal.winiarski@intel.com --- drivers/gpu/drm/i915/intel_guc_fwif.h | 39 +++++++++++++++++++++++++++++++++++ 1 file changed, 39 insertions(+) (limited to 'drivers/gpu/drm/i915/intel_guc_fwif.h') diff --git a/drivers/gpu/drm/i915/intel_guc_fwif.h b/drivers/gpu/drm/i915/intel_guc_fwif.h index 80c507435458..e24dbec2ead8 100644 --- a/drivers/gpu/drm/i915/intel_guc_fwif.h +++ b/drivers/gpu/drm/i915/intel_guc_fwif.h @@ -544,9 +544,36 @@ union guc_log_control { u32 value; } __packed; +struct guc_ctx_report { + u32 report_return_status; + u32 reserved1[64]; + u32 affected_count; + u32 reserved2[2]; +} __packed; + +/* GuC Shared Context Data Struct */ +struct guc_shared_ctx_data { + u32 addr_of_last_preempted_data_low; + u32 addr_of_last_preempted_data_high; + u32 addr_of_last_preempted_data_high_tmp; + u32 padding; + u32 is_mapped_to_proxy; + u32 proxy_ctx_id; + u32 engine_reset_ctx_id; + u32 media_reset_count; + u32 reserved1[8]; + u32 uk_last_ctx_switch_reason; + u32 was_reset; + u32 lrca_gpu_addr; + u64 execlist_ctx; + u32 reserved2[66]; + struct guc_ctx_report preempt_ctx_report[GUC_MAX_ENGINES_NUM]; +} __packed; + /* This Action will be programmed in C180 - SOFT_SCRATCH_O_REG */ enum intel_guc_action { INTEL_GUC_ACTION_DEFAULT = 0x0, + INTEL_GUC_ACTION_REQUEST_PREEMPTION = 0x2, INTEL_GUC_ACTION_SAMPLE_FORCEWAKE = 0x6, INTEL_GUC_ACTION_ALLOCATE_DOORBELL = 0x10, INTEL_GUC_ACTION_DEALLOCATE_DOORBELL = 0x20, @@ -562,6 +589,18 @@ enum intel_guc_action { INTEL_GUC_ACTION_LIMIT }; +enum intel_guc_preempt_options { + INTEL_GUC_PREEMPT_OPTION_DROP_WORK_Q = 0x4, + INTEL_GUC_PREEMPT_OPTION_DROP_SUBMIT_Q = 0x8, +}; + +enum intel_guc_report_status { + INTEL_GUC_REPORT_STATUS_UNKNOWN = 0x0, + INTEL_GUC_REPORT_STATUS_ACKED = 0x1, + INTEL_GUC_REPORT_STATUS_ERROR = 0x2, + INTEL_GUC_REPORT_STATUS_COMPLETE = 0x4, +}; + /* * The GuC sends its response to a command by overwriting the * command in SS0.
