The Linux framebuffer (fbdev) is a graphic hardware-independent abstraction layer to show graphics on a computer monitor, typically on the system console. It allows direct access to the framebuffer (the part of a computer's video memory containing a current video frame) using only the Linux kernel's own basic facilities and its device file system interface.

Phoronix: Intel GPU Driver Tries To Rip Out FBDEV Support Intel's Daniel Vetter is attempting for the Intel DRM graphics driver to remove support for its FBDEV frame-buffer layer with a new patch-set entitled "fbdev no more!", but will this finally usher in the killing of the Linux kernel's FBDEV subsystem?..

One and a half years ago there was a call for deprecating the Linux kernel's frame-buffer support but that still hasn't happened and the FBDEV support continues to advance, including with the in-development Linux 3.14 kernel. Laurent Pinchart had called for deprecating the Linux kernel's FBDEV code at the 2012 Linux Plumbers' Conference with the DRM and V4L2 drivers being superior in quality ...

Oct 27, 2015 · The "fbdev" variant now has support for dma-buf using a standard ioctl, which is explained in detail here. What is wrong with fbdev? The Linux kernel defines a user-space API that lets applications control displays via frame buffer drivers, also known as "fbdev" drivers. This is achieved via a set of file operations on "/dev/fb*" devices such ...

If fbdev_loopback doesn't display OSD windows then why it contains such functions like "mmap_osd0_buffers", "display_bitmap_osd0" and other similar that work with OSD windows? And also in comments in its code there is an example of bootargs for the application and it specifies OSD as OSD0=720x480x16:OSD1=0.
