From: Jason Ekstrand Date: Wed, 29 Jul 2015 22:28:51 +0000 (-0700) Subject: vk/cmd_buffer: Use an array to track all know anv_batch_bo objects X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3ed9cea84d42d7a5f37ed64d99a6a5ba064767f3;p=mesa.git vk/cmd_buffer: Use an array to track all know anv_batch_bo objects Instead of walking the list of batch and surface buffers, we simply keep track of all known batch and surface buffers as we build the command buffer. Then we use this new list to construct the validate list. --- diff --git a/src/vulkan/anv_cmd_buffer.c b/src/vulkan/anv_cmd_buffer.c index b47650aff73..2d46cc0c0ad 100644 --- a/src/vulkan/anv_cmd_buffer.c +++ b/src/vulkan/anv_cmd_buffer.c @@ -305,6 +305,13 @@ anv_cmd_buffer_chain_batch(struct anv_batch *batch, void *_data) if (result != VK_SUCCESS) return result; + struct anv_batch_bo **seen_bbo = anv_vector_add(&cmd_buffer->seen_bbos); + if (seen_bbo == NULL) { + anv_batch_bo_destroy(new_bbo, cmd_buffer->device); + return vk_error(VK_ERROR_OUT_OF_HOST_MEMORY); + } + *seen_bbo = new_bbo; + /* We set the end of the batch a little short so we would be sure we * have room for the chaining command.
