[PATCH/RFC v2 0/2] Mem-to-mem device framework

2009-12-23 Thread Pawel Osciak
Hello, this is the second version of the proposed implementation for mem-to-mem memory device framework. Your comments are very welcome. Changes since v1: - v4l2_m2m_buf_queue() now requires m2m_ctx as its argument - video_queue private data stores driver private data - a new submenu in kconfig

[PATCH v2 1/2] V4L: Add memory-to-memory device helper framework for V4L2.

2009-12-23 Thread Pawel Osciak
A mem-to-mem device is a device that uses memory buffers passed by userspace applications for both source and destination data. This is different from existing drivers, which use memory buffers for only one of those at once. In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type.

[PATCH v2 2/2] V4L: Add a mem-to-mem V4L2 framework test device.

2009-12-23 Thread Pawel Osciak
This is a virtual device driver for testing the mem-to-mem V4L2 framework. It simulates a device that uses memory buffers for both source and destination, processes the data and issues an IRQ (simulated by a timer). The device is capable of multi-instance, multi-buffer-per-transaction operation

This is an example application for testing mem-to-mem framework using mem2mem-testdev device. It is intended to be executed multiple times in parallel to test multi-instance operation and scheduling. Each process can be configured differently using command-line arguments. The application opens

The rotator device present on Samsung S3C and S5P series SoCs allows image rotation and flipping. It requires contiguous memory buffers to operate, as it does not have scatter-gather support. It is also an example of a memory-to-memory device, and so uses the mem-2-mem device V4L2 framework.
