关于mpp_init失败的询问
Closed this issue · 9 comments
您好,
我的环境如下:
Linux firefly 5.10.160 #111 SMP Tue Jul 4 11:41:59 CST 2023 aarch64 aarch64 aarch64 GNU/Linux
我遇到的问题:
mpp_init的时候会发生段错误.
用gdb简单调试有这样的信息:
Program received signal SIGSEGV, Segmentation fault.

查看dmesg | grep mpp,会有这样一段信息

目前毫无头绪,恳请大佬解答
跑下 mpp_platform_test，dmabuf 分配器用的 drm 还是 dmaheap？

感谢回复，运行mpp_plat_test后，日志输出如下：

dmabuf分配器，显示是使用drm
跑下 mpp_platform_test，dmabuf 分配器用的 drm 还是 dmaheap？
mpp[7816]: mpp_dmabuf_test: mpp dmabuf test start
mpp[7816]: mpp_dma_heap: os_allocator_dma_heap_open open dma heap type 0 system failed!
mpp[7816]: mpp_buffer: MppBufferService get_group failed to get allocater with mode 0 type 20004
mpp[7816]: mpp_dmabuf_test: get dmaheap buffer group failed ret -1
mpp[7816]: mpp_dmabuf_test: mpp dmabuf test done failed
这是运行mpp_dmabuf_test之后的信息，请问我该如何解决这个问题？
有 dma_heap 用 heap，然后再是有 drm 用 drm
有没有 /dev/dma_heap 目录和下面的 heap 文件
有没有 /dev/dma_heap 目录和下面的 heap 文件
是有这个目录的

然后我运行mpi_dec_test日志是这样的：

请问要如何解决
有 dma_heap 用 heap，然后再是有 drm 用 drm
需要我在哪里显示指定用哪个分配器吗？
权限，su 之后再运行
权限，su 之后再运行
非常感谢，问题已经全部解决
