通过SIMPLE_DEV_PM_OPS 定义这个驱动的suspend和resume函数,如果没有定义CONFIG_PM_SLEEP的时候就将CONFIG_PM_SLEEP定义为空函数,这样可以避免build error static SIMPLE_DEV_PM_OPS(asic3_led_pm_ops, asic3_led_suspend, asic3_led_resume); static struct platform_driver asic3_led_driver = { .probe = ...
SIMPLE_DEV_PM_OPS 定义如下: AI检测代码解析 #define SIMPLE_DEV_PM_OPS(name, suspend_fn, resume_fn) \ const struct dev_pm_ops name = { \ SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) \ } 1. 2. 3. 4. 如果定义CONFIG_PM_SLEEP的话,就给suspend和resume的函数指针赋值 AI检测代码解析...

At Boston DevOpsDays 2011 last week I hosted an open spaces discussion during which we prognosticated on what the everyday sysadmin would look like in 10 years time. A lively discussion followed and out of it we came up with a few key predictions that we all loosely agreed on; the futur...
But this is compiles, where ‘b’ is now initialized and ‘e’ is still not: for (int i = 0, b = 0, e; i < 10; i++) { } See this for previous behavior: https://dotnetfiddle.net/PmsuEz Seems to work in all versions. ...
You cannot do DevOps activities like automation or CI/CD without understanding the why of DevOps. In this meting we covered the why and how of DevOps and how it can benefit everyone in the organization. Then we discussed and walked through creating CI/CD pipelines in Azure DevOps. With ...
The new combination of pm_sleep_ptr() and DEFINE_SIMPLE_DEV_PM_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@...
