Previously, every time we put shader constants into the default constant buffer we called u_upload_alloc(), which mapped the buffer, and u_upload_unmap(). We had to unmap the buffer before calling svga_buffer_handle() to get the winsys handle for the buffer. But we really only need to do that the first time we reference the const buffer. Now we try to keep the upload manager's buffer mapped until we fill it or flush the command buffer. v2: add additional comment on the buffer unmapping code in svga_context_flush(), per Charmaine.
