http://p4web.freebsd.org/@@228881?ac=10 Change 228881 by prw35@pwithnall_zenith on 2013/05/20 22:47:01 Add a driver for the CHERI compositor This has been in use fairly extensively for several weeks now, and is solid enough to commit. It still needs post-hoc code review, and there are a number of FIXME comments in the code which can be addressed at a later date. These cover things such as using interrupt-based I/O rather than polled I/O, cleanly fixing some endianness issues, improving the efficiency of a few operations, and implementing a few missing ioctl()s. The code is fully commented, with overall documentation at the top of cheri_compositor.h. This commit does not add the driver to the hardware configuration, because the device is disabled in Qsys by default. A subsequent commit will enable the device in the configuration, so it can be reverted independently.
