From: Arto Merilainen <redacted> Currently job pinning is optimized to handle only the first buffer using a certain host1x_bo object and all subsequent buffers using the same host1x_bo are considered done. In most cases this is correct, however, in case the same host1x_bo is used in multiple gathers inside the same job, we skip also storing the device address (physical or iova) to this buffer. This patch reworks the host1x_job_pin() to store the device address to all gathers.
