D1s/f133-B 跑tina linux，有fb0设备，但是未执行LCD初始化函数

岁月快快快 · 2022-04-27 16:58:23

如题，用d1s点一块4寸的720x720的spi屏，系统跑起来后，能看到fb0设备，但是用GPIO模拟spi发命令和数据的引脚上没有量到有波形，一直是高电平，log也没看到跑进过LCD_panel_init函数；
设备树lcd相关的配置：

屏驱动代码是拷贝了lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/lcd/目录下的default_panel.c default_panel.h
在它的基础上加上SPI初始化代码的:

根据log定位到drivers/video/fbdev/sunxi/disp2/disp/dev_disp_debugfs.c中:

int dispdbg_init(void)
{
	my_dispdbg_root = debugfs_create_dir("dispdbg", NULL);
        printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
	if (!debugfs_create_file
	    ("command", 0644, my_dispdbg_root, NULL, &command_ops))
		goto Fail;
	if (!debugfs_create_file
	    ("name", 0644, my_dispdbg_root, NULL, &name_ops))
		goto Fail;
	if (!debugfs_create_file
	    ("start", 0644, my_dispdbg_root, NULL, &start_ops))
		goto Fail;
        printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
	if (!debugfs_create_file
	    ("param", 0644, my_dispdbg_root, NULL, &param_ops))
		goto Fail;
	if (!debugfs_create_file
	    ("info", 0644, my_dispdbg_root, NULL, &info_ops))
		goto Fail;
	if (!debugfs_create_file
		("dbglvl", 0644, my_dispdbg_root, NULL, &dbglvl_ops))
		goto Fail;
#if defined(CONFIG_SUNXI_MPP)
	if (debugfs_mpp_root) {
		if (!debugfs_create_file("vo", 0644, debugfs_mpp_root, NULL,
					 &vo_ops))
			goto Fail;
	}
#endif /*endif CONFIG_SUNXI_MPP */
	return 0;

Fail:
        printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
	debugfs_remove_recursive(my_dispdbg_root);
	my_dispdbg_root = NULL;
	return -ENOENT;
}

static const struct file_operations start_ops = {
	.write = dispdbg_start_write,
	.read = dispdbg_start_read,
	.open = dispdbg_start_open,
	.release = dispdbg_start_release,
};

static ssize_t dispdbg_start_write(struct file *file, const char __user *buf,
				   size_t count, loff_t *ppos)
{
        printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
	if (count >= sizeof(dispdbg_priv.start))
		return 0;
	if (copy_from_user(dispdbg_priv.start, buf, count)) {
		pr_warn("copy_from_user fail\n");
		return 0;
	}

	if (dispdbg_priv.start[count - 1] == 0x0A)
		dispdbg_priv.start[count - 1] = 0;
	else
		dispdbg_priv.start[count] = 0;
        printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
	dispdbg_process();
	return count;
}

static void dispdbg_process(void)
{
    ......
    if (!strncmp(dispdbg_priv.command, "enable", 6)) {
          printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
          lcd->enable(lcd);
    }    
    ......
}

调用的层次是
dispdbg_init()
if (!debugfs_create_file
("start", 0644, my_dispdbg_root, NULL, &start_ops));
dispdbg_start_write();
dispdbg_process();
if (!strncmp(dispdbg_priv.command, "enable", 6)) {
printk(KERN_INFO "[%s] %s: %d\n", __FILE__, __FUNCTION__, __LINE__);
lcd->enable(lcd);
}
在lcd->enable(lcd)中最后会调用到LCD_panel_init函数;
log看到的是只执行了：
if (!debugfs_create_file
("start", 0644, my_dispdbg_root, NULL, &start_ops));
start_ops里的.wrire函数dispdbg_start_write没有执行到，导致了LCD_panel_init函数没有被执行；

是要在应用程序里面操作fb0设备才会执行dispdbg_start_write 进行初始化？
但是用cat /dev/urandom > /dev/fb0 并没有看到dispdbg_start_write被执行到的log；

不是时序的问题，是初始化函数都没跑进去，发不了spi初始化数据。。。

修改了uboot的屏驱动和设备树，就可以初始化了，这样的话不就是内核里面的屏驱动没起作用

按全志SDK一贯做法，Linux驱动如果发现uboot已经开屏了，就不再进行初始化了。

有命令行可以强制在Linux重新初始化LCD。
