So to prevent this, let's add a workaround and make the sysfb to skip the "simple-framebuffer" registration when nvidia-drm.modeset=1 option is set and thus fallback to either efifb (on amd64 and arm64 UEFI devices) or vesafb (on amd64 BIOS devices)....
console=ttySAC0,115200 串口控制台 console=tty1 fbcon=rotate:2 液晶屏Framebuffer控制台,如果内核支持,可以在LCD屏幕上显示Linux内核启动过程,起点结束后在LCD屏幕上进入Shell控制台供用户操作。fbcon=rotate:2表示控制台旋转180度,若为1表示旋转90度,3旋转270度,0不旋转。 4. boot kernel zImage zImage 二进...

This function does the trick of converting the emulated framebuffer into high quality ASCII-art. It is slightly faster and less flexible the aa_render function. Note that to see the effect you need to call aa_flush too. First call to this function may take a while, because the rendering...
The latest generation of entry level ultra-low power MCUs The latest TouchGFX software builds on the TouchGFX Engine’s partial framebuffer, which can reduce the GUI RAM footprint by up to 90% and allow a simple user interface in as little as 16-20KB of internal MCU RAM. A new rendering...

* Possible values are: * - sti_font=<fb_fontname>: * <fb_fontname> is the name of one of the linux-kernel built-in * framebuffer font names (e.g. VGA8x16, SUN22x18). * This is only available if the fonts have been statically compiled * in with e.g. the CONFIG_FONT_8x16...
如果必要,修改你的内核代码中Framebuffer的驱动,使其Virtual_yres 等于两倍的Yres,并实际分配两倍分辨率大小的framebuffer内存。 配置内核,确保下列内容得到配置: CONFIG_ARM_THUMB=y CONFIG_AEABI=y CONFIG_BINDER=y CONFIG_ANDROID_LOG=y CONFIG_ANDROID_POWER=y ...
You still can augment the image content the application has rendered, since the framebuffer is part of the drawable, not the GL context. Doing so might have a negative impact on performance, but it might be so small that you never would even notice it. Since you want to do this only ...
It has been developed to provide programmers with fast access to graphics framebuffers and audio devices of various systems. The API has been brought to many different platforms including Mac OS, Linux, Windows, BeOS, Solaris, Irix and FreeBSD. SDL has been created for programmers who want ...
