为下面这段代码写一个makefile文件，#include <linux/init.h> #include <linux/module.h> #include <linux/kernel.h> #include <linux/interrupt.h> MODULE_LICENSE("GPL"); static int irq = 31; module_param(irq, int, 0); //MODULE_PARM_DESC(irq, "Interrupt request number (default: 31)"); static char *devname = "tasklet_dev"; module_param(devname, charp, 0); //MODULE_PARM_DESC(devname, "Name of the interrupt handler (default: interrupt_handler)"); static int count = 0; static irqreturn_t interrupt_handler(int irq, void *dev_id) { count++; printk(KERN_INFO "Interrupt called %d times\n", count); return IRQ_HANDLED; } static int __init interrupt_handler_init(void) { printk(KERN_INFO "=== Module starts...\n"); request_irq(irq, interrupt_handler, IRQF_SHARED, devname, &irq); printk(KERN_ERR "=== req_ret is %d\n", count); printk(KERN_INFO "=== %s request IRQ:%d success\n", devname, irq); return 0; } static void __exit interrupt_handler_exit(void) { free_irq(irq, &irq); printk(KERN_INFO "=== Module exits\n"); printk(KERN_INFO "=== %s request IRQ:%d leaving success...\n", devname, irq); } module_init(interrupt_handler_init); module_exit(interrupt_handler_exit);要求. 把加载、卸载内核模块以 install/uninstall 写入 Makefile 文件中。

以下是一个示例Makefile文件：

obj-m := interrupt_handler.o

KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

all:
	$(MAKE) -C $(KERNELDIR) M=$(PWD) modules

install:
	$(MAKE) -C $(KERNELDIR) M=$(PWD) modules_install
	depmod -a

uninstall:
	modprobe -r interrupt_handler
	rm -f /lib/modules/$(shell uname -r)/extra/interrupt_handler.ko
	depmod -a

clean:
	$(MAKE) -C $(KERNELDIR) M=$(PWD) clean

请注意，此Makefile文件假定您的模块名为"interrupt_handler"。您需要将其替换为您的模块名称。

使用上述Makefile文件，您可以使用以下命令来构建、安装、卸载和清理内核模块：

- `make`：构建内核模块。
- `make install`：安装内核模块。
- `make uninstall`：卸载内核模块。
- `make clean`：清理内核模块。

为下面这段代码写一个makefile文件,要求把all/install/uninstall 写入 Makefile 文件中。#include <linux/init.h> #include <linux/module.h> #include <linux/workqueue.h> #include <linux/sched.h> #include <linux/delay.h> #include <linux/timekeeping.h> MODULE_LICENSE("GPL"); static struct workqueue_struct* workqueue; static struct work_struct work1; static struct delayed_work work2; static int times; module_param(times, int, 5); int get_time(char* buff, int len) { struct timespec64 ts; struct tm tm_res; char time_string[40]; ktime_get_real_ts64(&ts); time64_to_tm(ts.tv_sec, 0, &tm_res); buff=tm_res.tm_year + 1900, tm_res.tm_mon + 1, tm_res.tm_mday,tm_res.tm_hour, tm_res.tm_min, tm_res.tm_sec; return 0; } static void real_time_work(struct work_struct* work) { char buff[40]; get_time(buff, sizeof(buff)); printk(KERN_INFO "%s\n",buff); } static void delayed_work(struct work_struct* work) { char buff[40]; get_time(buff, sizeof(buff)); printk(KERN_INFO "this is a delay work :%s\n", buff); } static int __init module_init(void) { printk(KERN_INFO "Initializing workqueue module.\n"); workqueue = create_workqueue("workqueue"); INIT_WORK(&work1, real_time_work); INIT_DELAYED_WORK(&work2, delayed_work); queue_work(workqueue, &work1); queue_delayed_work(workqueue, &work2, msecs_to_jiffies(10000)); return 0; } static void __exit module_exit(void) { printk(KERN_INFO "Exiting workqueue module.\n"); flush_workqueue(workqueue); destroy_workqueue(workqueue); } module_init(module_init); module_exit(module_exit);

以下是makefile文件的内容：

obj-m := workqueue.o

all:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules

install:
	make -C /lib/modules/$(shell uname -r)/build M=$(PWD) modules_install
	depmod -a

uninstall:
	rm /lib/modules/$(shell uname -r)/kernel/drivers/misc/workqueue.ko
	depmod -a

其中，obj-m定义了需要编译的模块文件，即workqueue.o。all指令使用make命令编译模块文件，install指令安装模块文件并更新依赖，uninstall指令删除已安装的模块文件并更新依赖。

以下是该模块的Makefile文件：

obj-m := workqueue_module.o

KERNELDIR ?= /lib/modules/$(shell uname -r)/build
PWD := $(shell pwd)

default:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) modules

install:
        insmod workqueue_module.ko

uninstall:
        rmmod workqueue_module.ko

clean:
        $(MAKE) -C $(KERNELDIR) M=$(PWD) clean

在当前目录下创建名为Makefile的文件，将上述代码复制到文件中保存。 确保该文件与工作目录中的workqueue_module.c文件处于同一目录中。 然后在终端中输入以下命令：

make
sudo make install

这将编译模块并将其加载到内核中。 要卸载模块，请在终端中输入以下命令：

sudo make uninstall
