Mobility Radeon HD 4530 @ubuntu20.04 显卡驱动不支持[GPU无法使用]

1. 源由

最近，在测试H264视频编解码时，发现一个重大的问题就是在ubuntu20.4上gstreamer不使用GPU做H264的解码，反而直接使用了CPU，导致100%的CPU占用率。

2. 显卡型号

通过命令行查询，本机显卡为：

  • [AMD/ATI] RV710/M92 Mobility Radeon HD 4530/4570/5145/530v/540v/545v

反馈信息提示：混合显卡（有专用的GPU）
"hybrid graphics system, with an iGP (integrated graphics processor inside the CPU) and a dedicated GPU. "

通过Wikipedia上List_of_AMD_graphics_processing_units确认，Radeon HD 4530应该具有H264硬编码/解码器。

3. 驱动安装

从目前H264解码情况看，解码时使用的是CPU资源，而非GPU。因此，怀疑驱动可能存在问题。

daniel@daniel-ThinkPad-SL410:~$ uname -m
x86_64

通过官网下载64位AMD/ATI Mobility Radeon HD 4530驱动，并进行安装。


3.1 问题1：内核version.h文件缺失

安装提示如下：

daniel@daniel-ThinkPad-SL410:~$ cat /usr/share/ati/fglrx-install.log
Detected a previous installation, /usr/share/ati/amd-uninstall.sh
Dryrun uninstall succeeded continuing with installation.
Check if system has the tools required for installation.
fglrx installation requires that the system have kernel headers.  /lib/modules/5.15.0-67-generic/build/include/linux/version.h cannot be found on this system.
One or more tools required for installation cannot be found on the system. Install the required tools before installing the fglrx driver.
Optionally, run the installer with --force option to install without the tools.
Forcing install will disable AMD hardware acceleration and may make your system unstable. Not recommended.

经过确认内核文件实际上已经安装

daniel@daniel-ThinkPad-SL410:~$ sudo apt-get install linux-headers-$(uname -r)
Reading package lists... Done
Building dependency tree
Reading state information... Done
linux-headers-5.15.0-67-generic is already the newest version (5.15.0-67.74~20.04.1).
0 upgraded, 0 newly installed, 0 to remove and 14 not upgraded.

通过以下步骤可以解决上述问题Missing “version.h” when installing fglrx

sudo cp -v /usr/include/linux/version.h /lib/modules/$(uname -r)/build/include/linux

3.2 问题2：驱动编译失败

安装过程失败，日志信息显示构建fglrx-8.97.100.7失败！

daniel@daniel-ThinkPad-SL410:~$ sudo ./amd-driver-installer-catalyst-13.1-legacy-linux-x86.x86_64.run

daniel@daniel-ThinkPad-SL410:~$ cat /usr/share/ati/fglrx-install.log
Check if system has the tools required for installation.
Uninstalling any previously installed drivers.

Creating symlink /var/lib/dkms/fglrx/8.97.100.7/source ->
                 /usr/src/fglrx-8.97.100.7

DKMS: add completed.

------------------------------
Deleting module version: 8.97.100.7
completely from the DKMS tree.
------------------------------
Done.

经过再次确认，**最新驱动(截止2023-03-13)**仅支持到内核3.4版本。而ubuntu20.4内核版本已经是5.15了。

3.3 问题3：尝试使用选项二“Generate Distribution Specific Driver Package”

3.3.1 安装execstack
