[参考译文] SK-AM62-LP：3D 立方体以低 fps 运行

尊敬的 Wilson：

CAT /sys/kernel/debug/pvr/status

应在运行 Kmscube 应用程序时提供 GPU 的状态。

此致、

Suren

您好、Suren、

感谢快速响应。 该命令返回

root@am62pxx-EVM：~# cat /sys/kernel/debug/pvr/status
CAT：无法打开"/sys/kernel/debug/pvr/status "：没有此类文件或目录

看起来我们必须启用调试和重新编译 rootfs。 是否有启用调试的方法？

此致、

Wilson

看上去 IMG 流氓驱动程序模块未插入。

您能否共享 lsmod 命令的输出？

此致、

Suren

您好、Suren、

如果从 OSPI 引导、则未列出任何模块。

root@am62pxx-evm:~# lsmod
Module                  Size  Used by
root@am62pxx-evm:~#

相比之下、如果 从 SD 引导、引导映像是由 Yocto10构建的。

尊敬的 Wilson：

新年快乐！

文件系统中存在图形库和二进制文件。 您需要在运行应用程序之前插入模块。  

在 init 脚本中、您会看到在运行 Kmscube 应用程序之前、我使用 insmod 插入了 pvrsrv.ko 模块。

希望这对您有所帮助！

此致、

Suren

您好、Suren、

新年快乐！！

从 SD 引导并找到 pvrsrvkm.ko (/lib/modules/6.6.44-ti-01478-g541c20281af7-dirty/updates/pvrsrvkm.ko)的路径<-由 Yocto 构建。

然后、从 OSPI 引导、运行 insmod、然后系统报告"Invalid module"(模块格式无效)。

我们的 SDK 是10.0.0.14、它的 Linux 内核版本是6.6.6.6.32。 我们是否应该转到10.1.0.33？ 刚刚检查了 SDK 10.1.33中的内核版本是6.6.58、而不是6.6.44。

或者、我们应该在 Yocto 的 linux-ti-stage_6.6.6.bb 中将 PV 版本修改为"6.6.6.6.32+git"？ 如果是、请建议使用 SRCREV。

谢谢！
