From 7dda98a434320080372ffa87b8fd29030d23ab20 Mon Sep 17 00:00:00 2001 From: Yang Rong Date: Mon, 9 Jun 2014 23:29:49 +0800 Subject: [PATCH] HSW: enable the surface's cache in HSW. HSW's surface cache control is changed, correct it. Also correct scratch size calculate. And disable exec flag for slm. When kernel parse cmd finish, need remove it totally Signed-off-by: Yang Rong Reviewed-by: Zhigang Gong --- src/cl_command_queue.c | 4 +-- src/cl_command_queue_gen7.c | 4 +-- src/cl_driver.h | 19 +++++++++++++- src/cl_driver_defs.c | 1 + src/intel/intel_gpgpu.c | 61 ++++++++++++++++++++++++++++----------------- 5 files changed, 61 insertions(+), 28 deletions(-) diff --git a/src/cl_command_queue.c b/src/cl_command_queue.c index a2109d7..e6553ec 100644 --- a/src/cl_command_queue.c +++ b/src/cl_command_queue.c @@ -157,9 +157,9 @@ cl_command_queue_bind_surface(cl_command_queue queue, cl_kernel k) offset = gbe_kernel_get_curbe_offset(k->opaque, GBE_CURBE_KERNEL_ARGUMENT, i); if (k->args[i].mem->type == CL_MEM_SUBBUFFER_TYPE) { struct _cl_mem_buffer* buffer = (struct _cl_mem_buffer*)k->args[i].mem; - cl_gpgpu_bind_buf(gpgpu, k->args[i].mem->bo, offset, buffer->sub_offset, cc_llc_l3); + cl_gpgpu_bind_buf(gpgpu, k->args[i].mem->bo, offset, buffer->sub_offset, cl_gpgpu_get_cache_ctrl()); } else { - cl_gpgpu_bind_buf(gpgpu, k->args[i].mem->bo, offset, 0, cc_llc_l3); + cl_gpgpu_bind_buf(gpgpu, k->args[i].mem->bo, offset, 0, cl_gpgpu_get_cache_ctrl()); } } diff --git a/src/cl_command_queue_gen7.c b/src/cl_command_queue_gen7.c index c9818e6..3401baa 100644 --- a/src/cl_command_queue_gen7.c +++ b/src/cl_command_queue_gen7.c @@ -31,7 +31,7 @@ #include #define MAX_GROUP_SIZE_IN_HALFSLICE 512 -static INLINE size_t cl_kernel_compute_batch_sz(cl_kernel k) { return 256+32; } +static INLINE size_t cl_kernel_compute_batch_sz(cl_kernel k) { return 256+128; } /* "Varing" payload is the part of the curbe that changes accross threads in the * same work group.
