概述

最近在工作中，有同事遇到LCD开机瞬间会闪现雪花屏的问题，而这类问题都有个共同点，那就是都发生在带GRAM的屏上，同样的问题，在休眠唤醒时也会出现。

其实这类问题的原理分析并不难，只是在给别人解释的时候不太好描述，因此，我特地写了这篇文章，好让大家能够更容易、更直观的理解这类花屏问题的原因，也希望能够帮助那些遇到同样问题的朋友。

The term was coined in 1964 by two Australian CSIRO researchers, Isabel Joy Bear and Richard G. Thomas, for an article in the journal Nature. In the article, the authors describe how the smell derives from an oil exuded by certain plants during dry periods, whereupon it is absorbed by clay-based soils and rocks.

Code

static void asyncEnabled(Dict* args, void* vAdmin, String* txid, struct Allocator* requestAlloc)
{
    struct Admin* admin = Identity_check((struct Admin*) vAdmin);
    int64_t enabled = admin->asyncEnabled;
    Dict d = Dict_CONST(String_CONST("asyncEnabled"), Int_OBJ(enabled), NULL);
    Admin_sendMessage(&d, txid, admin);
}
