Hello,
I'm trying to setup 720p performance test for parellel rgb display.
Which is documented on the reference manual as below
" The Parallel Display Interface (LCD Interface), which supports 720p60 display, is
located in the Audio-DMA (ADMA) Subsystem (please see the ADMA Subsystem for
details on the LCD Interface (LCDIF) block)."
It's because, 800x600x32bpp parallel rgb display works well with gstreamer video playback
but resolution increased to 1024x768, video flickers while playing mp4 video.
So, I'm assuming maybe the 32bpp format overhead makes this problem,
That's why I need 24 or 16 bpp setting.
So, I made some changed on
drivers\gpu\drm\mxsfb\mxsfb_drv.c :: mxsfb_probe()
drm_fbdev_generic_setup(drm, 32); --> drm_fbdev_generic_setup(drm, 16);
but, although the changes above,
drivers\gpu\drm\mxsfb\mxsfb_crtc.c :: mxsfb_set_pixel_fmt()
this function make fb format "DRM_FORMAT_XRGB8888", XR24.
My purpose is to setup 24bpp format but
drivers\gpu\drm\mxsfb\mxsfb_crtc.c :: mxsfb_set_pixel_fmt() <-- this function does not handle 24bpp case. it handles 24bpp case as error.
Q. How can I setup my framebuffer format as 24bit RGB888?
