驱动开发系列90 - Mesa Zink kopper 分析

一：相关 vulkan 接口

1. vkQueueWaitIdle

强制 CPU 等待 GPU.

调用堆栈：

ctx->base.blit

zink_blit

zink_kopper_present_readback

zink_kopper_present_readback

vkQueueWaitIdle

2. vkWaitForFences

CPU 等 GPU 把某些提交执行完.

调用堆栈：

screen->base.flush_front_buffer

zink_flush_frontbuffer

zink_kopper_present_queue

kopper_present

vkWaitForFences

3. vkCreateXcbSurfaceKHR

把一个X11（XCB）窗口变成Vulkan可以渲染的“Surface”

调用堆栈：

zink_resource_create_drawable

resource_create

zink_kopper_displaytarget_create

zink_kopper_displaytarget_create

kopper_CreateSurface

vkCreateXcbSurfaceKHR

4. vkGetPhysicalDeviceSu
