Hi, The value is the number of entries, not the size in bytes; BindingTableEntryCount for compute/media is programmed the same way as for all the other shader stages (where they too are divided by 4).
FWIW, the hardware will work without this patch because genX initializes the value as 0. When the value is zero, it means the GPU will not prefetch the binding table entries. -Kevin -----Original Message----- From: Landwerlin, Lionel G Sent: Monday, September 25, 2017 3:10 PM To: Rogovin, Kevin <kevin.rogo...@intel.com>; mesa-dev@lists.freedesktop.org Subject: Re: [Mesa-dev] [PATCH 04/22] i965: assign BindingTableEntryCount of INTERFACE_DESCRIPTOR_DATA On 25/09/17 11:34, kevin.rogo...@intel.com wrote: > From: Kevin Rogovin <kevin.rogo...@intel.com> > > Signed-off-by: Kevin Rogovin <kevin.rogo...@intel.com> > --- > src/mesa/drivers/dri/i965/genX_state_upload.c | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/src/mesa/drivers/dri/i965/genX_state_upload.c > b/src/mesa/drivers/dri/i965/genX_state_upload.c > index 6127616..bbb47ea 100644 > --- a/src/mesa/drivers/dri/i965/genX_state_upload.c > +++ b/src/mesa/drivers/dri/i965/genX_state_upload.c > @@ -4199,6 +4199,7 @@ genX(upload_cs_state)(struct brw_context *brw) > .SamplerStatePointer = stage_state->sampler_offset, > .SamplerCount = DIV_ROUND_UP(stage_state->sampler_count, 4) >> 2, > .BindingTablePointer = stage_state->bind_bo_offset, > + .BindingTableEntryCount = prog_data->binding_table.size_bytes / > + 4, I'm not sure this should be divided by 4.
