From: Jason Ekstrand Date: Tue, 28 Jan 2020 22:21:56 +0000 (-0600) Subject: anv: Re-use one old BT block in reset_batch_bo_chain X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ee4cdef9aeb7f2c576d9e6a31b1f07351829b795;p=mesa.git anv: Re-use one old BT block in reset_batch_bo_chain We intentionally throw away all but one BT block but then we set cmd_buffer->bt_block to ANV_STATE_NULL instead of the one we hung on to. This causes the command buffer to immediately re-emit STATE_BASE_ADDRESS the first time a BT is needed for no good reason.
