On ubuntu system, when run “git send-email”, the system will reply that:
git: 'send-email' is not a git command. See 'git --help'.
the solution will be follow:
sudo apt install git-email
The function interface
i40evf_init_module
|-->create_singlethread_workqueue(i40evf_driver_name);
|-->pci_register_driver(&i40evf_driver);
static struct pci_driver i40evf_driver = {
.name = i40evf_driver_name,
.id_table = i40evf_pci_tbl,
.probe = i40evf_probe,
.remove = i40evf_remove,
#ifdef CONFIG_PM
.suspend = i40evf_suspend,
.resume = i40evf_resume,
#endif
.shutdown = i40evf_shutdown,
};
i40evf_probe
1) enable pcie device;
pci_enable_device(pdev);
2) set dma mask to 64bits or 32bits
dma_set_mask_and_coherent();
3) request regions, indicate this pdev belonged to this driver
pci_request_regions(pdev, i40evf_driver_name);
4) enable error report, pcie device have its own error report machisum
pci_enable_pcie_error_reporting(pdev);
5) set pci master, then the device can access the DDR
pci_set_master(pdev);
6) alloc net device, mac support 16 queues
alloc_etherdev_mq(sizeof(struct i40evf_adapter), MAX_QUEUES);
7) set netdev dev
SET_NETDEV_DEV(netdev, &pdev->dev);
pci_set_drvdata(pdev, netdev);
8) adapter initialize
hw = &adapter->hw;
hw->back = adapter;
9) get mem base address
hw->hw_addr = ioremap(pci_resource_start(pdev, 0),
pci_resource_len(pdev, 0));
10) get the vendor_id, device_id, revision_id, susystem_vendor_id,
subsystem_device_id, bus_id, bus_func;
11) initialize two lock(ASQ and ARQ) for admin queue
12) initialize two list(mac, vlan) for filter
13) 4 work queue
i40evf_reset_task
i40evf_adminq_task
i40evf_watchdog_task
i40evf_init_task(delayed work queue)
14) call i40evf_init_task
schedule_delayed_work(&adapter->init_task,
secs_to_jiffies(5 * (pdev->devfn & 0x07)));
In this file I will analysize the HNS network dirvers
The hnae driver start by using class_create to create a new class name “hnae”.
After that, this driver provide some function for other module (hns_dsaf and
hns_enet_drv) to use. This funtions are as below:
hnae_register_notifier
hnae_unregister_notifier
hnae_get_handle
hnae_put_handle
hnae_reinit_handle
hnae_ae_register
hnae_ae_unregister
如何在不安装第三方工具的情况下，Ubuntu如何截图呢？这个问题一直困扰着我，今天终于找到一个不借用其他工具，使用Ubuntu系统自带的工具就可以完成截图了，这个工具就是gnome-screenshot。
先看帮助文档:1234567891011121314151617181920212223$ gnome-screenshot --helpUsage: gnome-screenshot [OPTION...]Help Options: -h, --help Show help options --help-all Show all help options --help-gapplication Show GApplication options --help-gtk Show GTK+ OptionsApplication Options: -c, --clipboard Send the grab directly to the clipboard -w, --window Grab a window instead of the entire screen -a, --area Grab an area of the screen instead of the entire screen -b, --include-border Include the window border with the screenshot -B, --remove-border Remove the window border from the screenshot -p, --include-pointer Include the pointer with the screenshot -d, --delay=seconds Take screenshot after specified delay [in seconds] -e, --border-effect=effect Effect to add to the border (shadow, border, vintage or none) -i, --interactive Interactively set options -f, --file=filename Save screenshot directly to this file --version Print version information and exit --display=DISPLAY X display to use
说一下主要的选项
-a: 选择区域
-w: 选择窗口
-c: 直接拷贝到剪贴板
-f: 直接保存到文件
常用的就是这几项了，所以可以省去安装什么shullter之类的工具了，如果仅仅是截图的话，还是挺方便的。
＃2015年已经过完了一年
今晚在做小二班的logo时，发现了一个生成logo网站，虽然不能保存为jpg格式，但可以自己通过截图软件保存下来，效果还是不错的，总比自己用ＰＳ做好看点：）
