From 102dadec811be75f61e22cea36268379bb545772 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Toni=20L=C3=B6nnberg?= Date: Wed, 7 Nov 2018 16:50:32 +0200 Subject: [PATCH] intel/decoder: tools: Use engine for decoding batch instructions The engine to which the batch was sent to is now set to the decoder context when decoding the batch. This is needed so that we can distinguish between instructions as the render and video pipe share some of the instruction opcodes. v2: The engine is now in the decoder context and the batch decoder uses a local function for finding the instruction for an engine. v3: Spec uses engine_mask now instead of engine, replaced engine class enums with the definitions from UAPI. v4: Fix up aubinator_viewer (Lionel) Reviewed-by: Lionel Landwerlin --- src/intel/common/gen_batch_decoder.c | 25 ++++--- src/intel/common/gen_decoder.c | 7 +- src/intel/common/gen_decoder.h | 6 +- src/intel/tools/aubinator.c | 3 +- src/intel/tools/aubinator_error_decode.c | 73 ++++++++++---------- src/intel/tools/aubinator_viewer.cpp | 4 +- src/intel/tools/aubinator_viewer.h | 1 + src/intel/tools/aubinator_viewer_decoder.cpp | 3 +- 8 files changed, 69 insertions(+), 53 deletions(-) diff --git a/src/intel/common/gen_batch_decoder.c b/src/intel/common/gen_batch_decoder.c index 36ee7706e40..ff29074c6d1 100644 --- a/src/intel/common/gen_batch_decoder.c +++ b/src/intel/common/gen_batch_decoder.c @@ -45,6 +45,7 @@ gen_batch_decode_ctx_init(struct gen_batch_decode_ctx *ctx, ctx->fp = fp;
