Wayland与Weston简介_weston wayland-CSDN博客

GPU的使用是需要结合图形显示系统的，对于不同的图形显示系统，GPU驱动库也有所不同，所以要使用GPU必须先了解Linux下的图形显示方式。

linux是一个基于命令行的操作系统，图形界面是一个应用程序（而windows的图形界面是操作系统的一部分）。 Linux中图形显示所涉及的知识,简单框图如下所示：

下面简单介绍一些图形相关的知识，包括内核驱动、图形API接口、显示管理器、窗口管理器、GUI应用工具，桌面环境等等。

3.1. DRM/KMS
Direct Rendering Manager(DRM)子系统用于linux内核显示、图形和合成子系统的管理。通常使用该框架来控制显示接口和外部显示器（控制分辨率，频率，多屏显示等）、输出画面到显示面板、硬件渲染画面等。

DRM是在内核空间，用户空间使用，通常通过相应的 libdrm 库函数调用，也可以直接ioctl访问设备文件或者使用sysfs文件DRM驱动通信，使用OpenGL或Vulkan等图形API的应用程序可以通过这些设备文件与GPU进行交互，以实现硬件加速渲染等。

3.2. libdrm
libdrm库，为DRM驱动ioctl提供了包装函数，避免了将内核接口直接暴露给应用程序，通过libdrm对显示资源进行统一访问，libdrm将命令传递到内核最终由DRM驱动接管各应用的请求并处理。

libdrm是一个底层库，通常被其他图形驱动程序调用，例如Mesa、X、libva和类似项目。

3.3. OpenGL
OpenGL是一组专门涉及2D和3D图形的硬件加速渲染的规范，至于内部具体每个函数是如何实现，将由编写OpenGL库的人自行决定，实际通常是GPU的生产商。 OpenGL API实现通常是C语言，也有其他语言的实现，如Java、Golang和Rust等。

OpenGL ES（OpenGL for Embedded Systems）是适用于嵌入式设备的OpenGL规范，针对Android手机和iPhone等嵌入式设备。

EGL 是一个依赖于平台的API，是渲染 API（如 OpenGL ES）和原生窗口系统之间的接口。通常来说，OpenGL 是一个操作 GPU 的 API，它通过驱动向 GPU 发送相关指令，控制图形渲染管线状态机的运行状态，但是当涉及到与本地窗口系统进行交互时，就需要这么一个中间层，因此 EGL 被设计出来，作为 OpenGL 和原生窗口系统之间的桥梁,且它与平台无关的。

3.4. Vulkan
Vulkan 是一个低开销、跨平台的2D和3D图形与计算的应用程序接口（API），能够跨平台高效访问GPU。

Vulkan的设计目标是提供一个更轻量级、更高效的图形API，以取代OpenGL等传统的图形API。作为业内开放标准的现代GPU API，开发人员能够编写可移植到多个不同平台的应用程序。

3.5. Mesa
Mesa 也称为Mesa3D和Mesa 3D图形库，是OpenGL、Vulkan和其他图形API规范的开源实现。 Mesa将这些API规范转换为特定于供应商的图形硬件驱动程序。

Mesa项目最初是作为OpenGL规范的开源实现而开始。经过多年来发展，具有跨平台支持、高性能、开源和扩展性等特点，并且该项目已经扩展到实现更多的图形API，包括OpenGL ES、OpenCL、OpenMAX、VDPAU、VA-API、Vulkan和EGL。

3.6. X Window System
大多数基于Linux的发行版都使用 X Window System (X11,或者简称X) ，它是基于客户端-服务器体系结构，可以在远程环境中使用。

X Window系统基于客户端-服务器体系结构，客户端和服务器可以在同一台机器上也可以不在同一台机器上，就需要一个在客户端和服务器之间传递消息的协议。 X11协议就是负责消息传递，当客户端和服务器在同一台机器上时，消息通过UNIX套接字进行交换，不同机器上通过网络（TCP/IP）

3.7. Wayland
Wayland 是一种显示服务协议，不依赖客户端-服务器体系结构，旨在提供一个现代、安全的的Linux和其他类Unix操作系统窗口系统取代X Window system，而Weston是Wayland开源显示协议的参考实现

3.8. EGLFS
EGLFS是QT自带的一个平台插件，可以在EGL和OpenGL ES之上运行Qt应用程序，而不需要通过X11或Wayland这样的实际窗口系统。 EGLFS还支持软件渲染窗口，如QWidget的内容使用CPU渲染成图像，然后上传到纹理中，并由插件进行合成。

四、T527 GPU使用
T527 GPU的使用，还要分两种GPU驱动来说，一种是闭源驱动mali，一种是开源panforst驱动。

4.1、闭源GPU驱动的测试

由于部分 Android 平台 GKI 的要求，默认不开启CONFIG_DEBUG_FS, 导致 cpu_monitor 工具无法获取gpu 的频率信息，于是 mali‑valhall dirver 将 debugfs 相应的功能移动到 sysfs。具体的路径位于：
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu。接下来介绍下 sysfs 调试节点的使用方法。
scene_ctrl：可读写，GPU 是否运行在性能模式
echo 1 >scene_ctrl; GPU将会关闭dvfs，运行在最高频。
0：关闭
1：开启

sunxi_gpu_freq：可读写，用来查看、改变 GPU 的频率
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # cat sunxi_gpu_freq
Frequency:696MHz; //GPU当前的频率
Utilisation from last show:0%; //GPU当前的负载率，这两个信息是用户最常用的
// 更改GPU的频率，单位是MHz，将GPU频率设为600MHz；同时会将dvfs关闭
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # echo 600 >sunxi_gpu_freq
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # cat sunxi_gpu_freq
Frequency:600MHz;
Utilisation from last show:0%;
如果更改频率失败，会有以下提示：
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # echo 1 >sunxi_gpu_freq
[ 1212.444659] mali 1800000.gpu: sunxi:mali_kbase:set gpu core clock to 1000000 err ‑22!
注意：虽然更改频率失败，但仍会影响dvfs_ctrl的值，将dvfs_ctrl设为0，即dvfs不再起作用。读写频率的单位MHz。

sunxi_gpu_volt：可读写，用来查看、改变 GPU 的电压 (GPU 独立供电时才能更改电压)
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # cat sunxi_gpu_volt
920mv
//非独立供电时，尝试更改电压会报错
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # echo 900 >sunxi_gpu_volt
[ 1315.910428] mali 1800000.gpu: sunxi:mali_kbase:[ERR]: GPU not support change voltage!!!
ash: write error: Operation not permitted
注意：读写电压的单位是mv

sunxi_gpu_dvfs：可读写，用来查看、配置 dvfs 对 GPU 的控制
echo 0 >sunxi_gpu_dvfs；//dvfs将不再影响GPU的频率，这个配置，只有内核开启PM_DEVFREQ
并且GPU驱动开启CONFIG_MALI_DEVFREQ选项时才有效。

sunxi_gpu_info：只读，查看 GPU 详细的运行信息和几组重要寄存器的值
/sys/devices/platform/soc@3000000/1800000.gpu/sunxi_gpu # cat sunxi_gpu_info
voltage:920mV;
idle:on;
scenectrl:off;
dvfs:off;
independent_power:no;
Frequency:600MHz;
Utilisation from last show:0%;
Register state:
GPU_IRQ_RAWSTAT=0x00000000 GPU_STATUS=0x00000100
JOB_IRQ_RAWSTAT=0x90910010 JOB_IRQ_JS_STATE=0x00000001

JS2_STATUS=0x00000000 JS2_HEAD_LO=0x00000000
MMU_IRQ_RAWSTAT=0x00000000 GPU_FAULTSTATUS=0x00000000
GPU_IRQ_MASK=0x00000000 JOB_IRQ_MASK=0x00000000 MMU_IRQ_MASK=0x00000000
PWR_OVERRIDE0=0x00000000 PWR_OVERRIDE1=0x00000000
SHADER_CONFIG=0x20000000 L2_MMU_CONFIG=0x00000000
TILER_CONFIG=0x00000000 JM_CONFIG=0x000f0000

4.2、开源GPU驱动Panfrost的测试

具体的路径位于：/sys/devices/platform/soc@3000000/1800000.gpu/devfreq/1800000.gpu

注意：路径和闭源驱动不同了。

embfly-x527:/sys/devices/platform/soc@3000000/1800000.gpu/devfreq/1800000.gp
available_frequencies  max_freq               subsystem
available_governors    min_freq               target_freq
cur_freq               name                   timer
device                 polling_interval       trans_stat
governor               power                  uevent

available_frequencies表示可用的GPU频率：

#cat available_frequencies
150000000 200000000 300000000 400000000 600000000 696000000

可以看到最高频率是696Mhz，这个和G57标称的有区别，G57标称的最高频率是850MHZ ,而全志只能让它跑在700Mhz,分析估计是散热问题，跑太快，发热量高，最后导致不稳定。

available_governors表示GPU支持的工作方式，和CPU比较类似：

#cat available_governors
userspace performance simple_ondemand

GPU的工作支持performance(最高性能)，也支持simple_ondemand按照需求调度。那么默认是什么工作方式呢？通过如下指令可以获得：

#cat governor
simple_ondemand

目前不得而知如何让其默认工作在性能模式。

4.3、开源GPU驱动Panfrost下glmark2的跑分

glmark2是一个用于评估OpenGL（图形编程接口）性能的基准测试工具。它可以测试图形处理器（GPU）在处理图形渲染任务时的性能表现。
