One problem I'm having is that after a while, the LCD blanks out (I do have fbcon support enabled so I can use it as a glass TTY - no keyboard) How can I keep this from happening? Once it does, is there any way to get it back on (remember, no keyboard)? check man console_codes -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
OMAPFB: LL pointer dereference because of uninitialized mutex
Hello, I'm trying to add support for a omap3 board. But I get a NULL pointer dereference during initialization of the lcd panel driver because framebufferInfo-mm_lock wasn't initialized. Code of the lcd driver: http://pastebin.com/m44ccc56d (nothing special) Stack trace: __mutex_lock_slowpath() mutex_lock() set_fb_fix() omapfb_do_probe() devkit8000_panel_probe() my probe function platform_drv_probe() ... It get's initialized in register_framebuffer() but in my case the probe function gets called before register_framebuffer(). Once I added the missing inits to framebuffer_alloc() (drivers/video/fbsysfs.c) it works fine: mutex_init(info-lock); mutex_init(info-mm_lock); How I'm intended to fix this? -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
