At the moment the vme bridge drivers are written in a way that only allows them to support one bridge at a time. Modify the drivers to enable more than one bridge to be present per board. Signed-off-by:

Specify Kconfig dependencies, and include warnings for building as a module udlfb is dependent on FB_DEFERRED_IO, FB_SYS_*, and FB_MODE_HELPERS Because many kernels do not include defio (which cannot be built as a module), yet users want to be able to build udlfb as a module later, udlfb has ifdefs and these dependency warnings to help udlfb build with or without certain dependencies, but also print warnings for any lost function. Even though this kind of flexibility isn't common, we've gotten feedback from a significant portion of users that they were frustrated without it. Signed-off-by:

Add support for fbdev mmap clients who don't send damage ioctls Because DisplayLink devices are out on the other end of usb, their "framebuffer" is just normal system memory. So memory mapped writes don't automatically trigger anything. So up to this point, standard fbdev clients who rely on mmap() will get an unchanging screen. This patch makes udlfb a client of Jaya Kumar's defio framework - which sets up page fault triggers, and those faults are accumulated and sent to udlfb on a defferred basis, to process as damage notifications for the framebuffer. Because this involves more overhead than a notification directly from the application (e.g. just passing on X DAMAGE extension notifications), a sysfs attribute is provided by udlfb to control defio support. /sys/class/graphics/fb*/use_defio - writing a "0" to this file before calling mmap() causes defio to not be initialized - instead udlfb will rely on getting damage notifications directly through the damage ioctl. There are unsolved rendering problems with defio (horizontal dead regions on framebuffer, that accumulate over time) which still needs a fix. Signed-off-by:

Rework rendering for improved performance Approx 10-20% gain avg across several "benchmarks": x11perf, gtkperf, glxgears Moves from a single pre-alloc'd urb protected by a long-held mutex To a list of (4) pre-alloc'd urbs which can be dispatched asynchonously Improved rendering algorithm to hardware with lower CPU consumption, fewer system memory accesses, and slightly higher compression. Better scalability to multiple processors, especially with multiple framebuffers active. Signed-off-by:

Rework probe to use refcounts and std functions Because the different parts of the driver (usb, fbdev) tear down in different orders, the driver previously could crash accessing data that had already been freed. Refcounting system used to handle. Reworked probe to make use of refcounts, set mode using std fbops, and set up sysfs and pre-allocated urbs. Signed-off-by:

Add sysfs controls for edid and performance metrics There are 8 new files exposed in /sys/class/graphics/fb* edid - returns 128 byte edid blog, suitable for parsing with parse-edid metrics_bytes_identical metrics_bytes_rendered metrics_bytes_sent metrics_cpu_kcycles_used metrics_misc and metrics_reset, which resets all perf metrics to zero The 6 perf metrics are of type atomic_t. So these metrics return precise results for short benchmarks, but any test approx a minute or longer runtime may roll over. Signed-off-by:

Move to more consistent naming scheme All udlfb functions start with udlfb_ All functions for udlfb's fbdev interface start with udlfb_ops_ All functinos for udlfb's usb interface start with udlfb_usb_ Signed-off-by:

Add functions to pre-allocate and free usb bulk urbs for core render path. Udlfb currently allocates a single urb, guarded by a mutex, that is a key bottleneck. Because udlfb sends so much data, preallocation is most efficient. Functions will be used by new rendering functions in later patches. Signed-off-by:

It turns out that Mimio has a userspace solution for this product using libusb, and the in-kernel driver is just getting in the way now and causing problems. So they have asked that the in-kernel driver be removed. As the staging driver wasn't quite working anyway, and Mimio supports their libusb solution for all distros, I am removing the in-kernel driver. The libusb solution can be downloaded from: http://www.mimio.com/downloads/mimio_studio_software/linux.asp Cc: <mwilder@cs.nmsu.edu> Cc: Phil Hannent <phil@hannent.co.uk> Cc: Marc Rousseau <Marc.Rousseau@mimio.com> Cc: stable <stable@kernel.org> Signed-off-by:
