Instead, data is serialized into +virgl internal command and sent using VIRTIO_GPU_CMD_SUBMIT_3D +comand. This command is opaque for rproxy/rvdds and serialized cmd buffer +is just forwarded to virglrenderer, where it is deserialized and +used for initialization of internal "gpu" memory with this data. +2) glMapBuffer --- this calls TRANSFER_FROM_HOST_3D, which asks host/rproxy--> +rvdds/virglrenderer to update backing memory (on source) with buffer data. +And further this backing memory is mapped to guest application. +In case of UHMI, TRANSFER_FROM_HOST_3D is not implemented, thus the memory is +not "initialized". +3) Modify buffer memory, but not whole memory, just some chunks. +4) glUnmapBuffer --- this will trigger VIRTIO_GPU_CMD_TRANSFER_TO_HOST_3D +command, which will send to target whole buffer memory and will overwrite +previous memory. It's ok for modified in step 3 memory, but other is +just garbage (I always saw zero filled memory). + +The above scenario produces artifacts on buffer-scene of glmark, in case of +"update-method=map", which forces glmark to use 1-4 flow. + +As a workaround, fill buffer backing memory with data on step 1. + +Issue: EXDCLXXII-420 + +Upstream-Status: Pending +--- + src/gallium/auxiliary/util/u_inlines.h | 21 +++++++++++++++++++++ + src/mesa/state_tracker/st_cb_bufferobjects.c | 4 +++- + 2 files changed, 24 insertions(+), 1 deletion(-) + +diff --git a/src/gallium/auxiliary/util/u_inlines.h b/src/gallium/auxiliary/util/u_inlines.h +index dee6f8f..4745f7b 100644 +--- a/src/gallium/auxiliary/util/u_inlines.h ++++ b/src/gallium/auxiliary/util/u_inlines.h +@@ -462,6 +462,27 @@ pipe_buffer_read(struct pipe_context *pipe, + pipe_buffer_unmap(pipe, src_transfer);
