版主，我下载了pad版的kernel，烧写后出现空指针错误。麻烦帮忙分析下，谢谢。
在rk_fb.c中
#if defined(CONFIG_ION_ROCKCHIP)
static int rk_fb_alloc_buffer_by_ion(struct fb_info *fbi,
struct rk_lcdc_win *win,
unsigned long fb_mem_size)
{
。。。
if (dev_drv->iommu_enabled)
handle = ion_alloc(rk_fb->ion_client, (size_t) fb_mem_size, 0,
ION_HEAP(ION_VMALLOC_HEAP_ID), 0);
else
handle = ion_alloc(rk_fb->ion_client, (size_t) fb_mem_size, 0,
ION_HEAP(ION_CMA_HEAP_ID), 0);
if (IS_ERR(handle)) {
dev_err(fbi->device, "failed to ion_alloc:%ld\n",
PTR_ERR(handle));
return -ENOMEM;
}。。。
}
打印信息如下：
