From: Thomas Hellstrom <thellstrom@xxxxxxxxxx> The SVGA3dCmdDXGenMips command uses a shader-resource view to access the underlying surface. Normally accesses using that view-type are not dirtying the underlying surface, but that particular command is an exception. Mark the surface gpu-dirty after a SVGA3dCmdDXGenMips command has been submitted. This fixes the piglit getteximage-formats test run with SVGA_FORCE_COHERENT=1 Fixes: a9f58c456e9d ("drm/vmwgfx: Be more restrictive when dirtying resource") Signed-off-by: Thomas Hellstrom <thellstrom@xxxxxxxxxx> Reviewed-by: Charmaine Lee <charmainel@xxxxxxxxxx> Reviewed-by: Roland Scheidegger <sroland@xxxxxxxxxx> Signed-off-by: Zack Rusin <zackr@xxxxxxxxxx> --- drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c | 20 ++++++++++++++++---- 1 file changed, 16 insertions(+), 4 deletions(-) diff --git a/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c b/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c index ab752b102c9e..ca5360efa172 100644 --- a/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c +++ b/drivers/gpu/drm/vmwgfx/vmwgfx_execbuf.c @@ -2763,12 +2763,24 @@ static int vmw_cmd_dx_genmips(struct vmw_private *dev_priv, { VMW_DECLARE_CMD_VAR(*cmd, SVGA3dCmdDXGenMips) = container_of(header, typeof(*cmd), header); - struct vmw_resource *ret; + struct vmw_resource *view; + struct vmw_res_cache_entry *rcache; - ret = vmw_view_id_val_add(sw_context, vmw_view_sr, - cmd->body.shaderResourceViewId); + view = vmw_view_id_val_add(sw_context, vmw_view_sr, + cmd->body.shaderResourceViewId); + if (IS_ERR(view)) + return PTR_ERR(view); - return PTR_ERR_OR_ZERO(ret); + /* + * Normally the shader-resource view is not gpu-dirtying, but for + * this particular command it is... + * So mark the last looked-up surface, which is the surface + * the view points to, gpu-dirty. + */ + rcache = &sw_context->res_cache[vmw_res_surface]; + vmw_validation_res_set_dirty(sw_context->ctx, rcache->private, + VMW_RES_DIRTY_SET); + return 0; } /** -- 2.27.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
