Staging: udlfb: improved rendering performance 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: Bernie Thompson <bernie@plugable.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Staging: udlfb: pre-allocated urb list helpers 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: Bernie Thompson <bernie@plugable.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

staging: udlfb: fix incorrect fb_defio implementation for multiple framebuffers Fix fb_defio bug in udlfb for multiple framebuffers Previously when using fb_defio with multiple DisplayLink attached displays udlfb incorrectly used a shared datastructure where it needed to have one per fb_info struct. This was completely broken and caused all kinds of problems, including rendering to one framebuffer affecting others.

staging: udlfb: revamp reference handling to insure successful shutdown Revamp reference handling and synchronization for unload/shutdown Udlfb is a "virtual" framebuffer device that really exists on two separate stacks: at the bottom of the framebuffer interface, and on top of USB.

staging: udlfb: enhance EDID and mode handling support Enhance EDID and mode table handling * Adds support for lower-end DL chips on higher-end monitors * Adds support for using fbdev standard EDID parsing and handling * Adds support for more dynamic reallocation of framebuffer, based on new EDID Queries EDID from hardware with several retries then queries DisplayLink chip for max pixel area via vendor descriptor. Uses existing fbdev mode handling service funcations to build mode list of common modes between adapter and monitor. This enables lower-end chips (e.g. DL-125) to successfully pick a compatible mode on higher end monitors (e.g. whose default mode is over 1280x1024). Reallocate framebuffer if necessary in response to new max mode. Signed-off-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Staging: udlfb: add dynamic modeset support Add dynamic modeset support udlfb uses EDID to find the monitor’s preferred mode udlfb no longer has fixed mode tables – it’s able to set any mode dynamically, from the standard VESA timing characteristics of the monitor. Draws from probe and setmode code of both displaylink-mod 0.3 branch of Roberto De Ioris, and Jaya Kumar's displaylinkfb. Lays foundation for defio support and making backbuffer optional. With additional changes to minimize diffs and clean for checkpatch.pl style. Does not yet include new ioctls or refcount/mutex code from displaylink-mod. Tested to work with existing xf-video-displaylink X server unmodified. Signed-off-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
