关于mpp_init失败的询问 #670

Closed FORGETSCHOLAR closed 2 months ago

FORGETSCHOLAR commented 2 months ago

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. 0x0000007ff786e974 in mpp_buffer_create () from /lib/aarch64-linux-gnu/librockchip_mpp.so.1 (gdb) bt

(gdb) quit

查看dmesg | grep mpp,会有这样一段信息 [ 5.713838] mpp_rkvenc2 fdbd0000.rkvenc-core: Adding to iommu group 10 [ 5.713985] mpp_rkvenc2 fdbd0000.rkvenc-core: probing start [ 5.714096] mpp_rkvenc2 fdbd0000.rkvenc-core: dev_pm_opp_set_regulators: no regulator (venc) found: -19 [ 5.714131] mpp_rkvenc2 fdbd0000.rkvenc-core: attach ccu as core 0 [ 5.714231] mpp_rkvenc2 fdbd0000.rkvenc-core: probing finish [ 5.714288] mpp_rkvenc2 fdbe0000.rkvenc-core: Adding to iommu group 11 [ 5.714442] mpp_rkvenc2 fdbe0000.rkvenc-core: probing start [ 5.714544] mpp_rkvenc2 fdbe0000.rkvenc-core: dev_pm_opp_set_regulators: no regulator (venc) found: -19 [ 5.714599] mpp_rkvenc2 fdbe0000.rkvenc-core: attach ccu as core 1 [ 5.714701] mpp_rkvenc2 fdbe0000.rkvenc-core: probing finish [ 5.715096] mpp_av1dec: Adding child /av1d@fdc70000 [ 5.715153] mpp_av1dec: register device av1d-master [ 5.715175] mpp_av1dec av1d-master: av1_iommu_of_xlate,784 [ 5.715215] mpp_av1dec av1d-master: Adding to iommu group 16 [ 5.715396] mpp_av1dec av1d-master: probing start [ 5.715581] mpp_av1dec av1d-master: probing finish [ 5.715605] mpp_service mpp-srv: probe success

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？

@HermanChen 感谢回复，运行mpp_plat_test后，日志输出如下： mpp_platform: client 12 driver is not ready! mpp[424074]: mpp_platform: client 18 driver is not ready! mpp[424074]: mpp_plat_test: kernel version: 5.10 mpp[424074]: mpp_plat_test: ioctl version: mpp_service mpp[424074]: mpp_plat_test: mpp[424074]: mpp_plat_test: chip name: rockchip,roc-rk3588s-pc rockchip,rk3588 mpp[424074]: mpp_plat_test: mpp[424074]: mpp_plat_test: chip vcodec type 1009221a mpp[424074]: mpp_plat_test: found vpu2 codec mpp[424074]: mpp_plat_test: found rkvdec decoder mpp[424074]: mpp_plat_test: found rk jpeg decoder mpp[424074]: mpp_plat_test: found rkvenc encoder mpp[424074]: mpp_plat_test: mpp[424074]: mpp_plat_test: start probing decoder device name: mpp[424074]: mpp_plat_test: H.264 decoder: /dev/mpp_service mpp[424074]: mpp_plat_test: H.265 decoder: /dev/mpp_service mpp[424074]: mpp_plat_test: MJPEG decoder: /dev/mpp_service mpp[424074]: mpp_plat_test: VP9 decoder: /dev/mpp_service mpp[424074]: mpp_plat_test: avs+ decoder: /dev/mpp_service mpp[424074]: mpp_plat_test: mpp[424074]: mpp_plat_test: start probing encoder device name: mpp[424074]: mpp_plat_test: H.264 encoder: /dev/mpp_service mpp[424074]: mpp_plat_test: H.265 encoder: /dev/mpp_service mpp[424074]: mpp_plat_test: MJPEG encoder: /dev/mpp_service mpp[424074]: mpp_plat_test: mpp platform test done

dmabuf分配器，显示是使用drm

FORGETSCHOLAR commented 2 months ago

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

HermanChen commented 2 months ago

有没有 /dev/dma_heap 目录和下面的 heap 文件

FORGETSCHOLAR commented 2 months ago

有没有 /dev/dma_heap 目录和下面的 heap 文件

是有这个目录的 firefly@firefly:~/niehaoyang$ ll -a /dev/dma_heap/ 总用量 0 drwxr-xr-x 2 root root 160 1月 1 1970 ./ drwxr-xr-x 18 root root 4280 9月 15 01:27 ../ crw------- 1 root root 251, 4 9月 8 02:41 cma crw------- 1 root root 251, 5 9月 8 02:41 cma-uncached crw------- 1 root root 251, 0 9月 8 02:41 system crw------- 1 root root 251, 1 9月 8 02:41 system-dma32 crw------- 1 root root 251, 2 9月 8 02:41 system-uncached crw------- 1 root root 251, 3 9月 8 02:41 system-uncached-dma32

然后我运行mpi_dec_test日志是这样的： 运行mpi_dec_test有如下问题： firefly@firefly:~/niehaoyang$ ./mpp/build/linux/aarch64/test/mpi_dec_test -t 7 -i /home/firefly/niehaoyang/rknn_yolov5_demo/build/build_linux_aarch64/rknn_yolov5_demo/street.h264 mpp[774424]: mpi_dec_utils: failed to open input file /home/firefly/niehaoyang/rknn_yolov5_demo/build/build_linux_aarch64/rknn_yolov5_demo/street.h264 mpp[774424]: mpi_dec_utils: cmd parse result: mpp[774424]: mpi_dec_utils: input file name: /home/firefly/niehaoyang/rknn_yolov5_demo/build/build_linux_aarch64/rknn_yolov5_demo/street.h264 mpp[774424]: mpi_dec_utils: output file name: mpp[774424]: mpi_dec_utils: width : 0 mpp[774424]: mpi_dec_utils: height : 0 mpp[774424]: mpi_dec_utils: type : 7 mpp[774424]: mpi_dec_utils: max frames : 0 mpp[774424]: mpi_dec_test: mpi_dec_test start mpp[774424]: mpp_info: mpp version: e9d95ce4 author: Yandong Lin 2024-09-06 fix[h265d]: fix output err causeby refs cleard mpp[774424]: mpi_dec_test: 0x55a962db00 mpi_dec_test decoder test start w 0 h 0 type 7 mpp[774424]: mpp_dma_heap: os_allocator_dma_heap_open open dma heap type 0 system failed! mpp[774424]: mpp_buffer: MppBufferService get_group failed to get allocater with mode 0 type 20001 mpp[774424]: mpp_buffer: mpp_buffer_group_limit_config input invalid group (nil) mpp[774424]: mpp_platform: client 12 driver is not ready! mpp[774424]: mpp_platform: client 18 driver is not ready! mpp[774424]: mpp_dma_heap: os_allocator_dma_heap_open open dma heap type 0 system-uncached failed! mpp[774424]: mpp_buffer: MppBufferService get_group failed to get allocater with mode 0 type 1 mpp[774424]: mpp_hal: mpp_hal_init hal h264d_rkdec init failed ret -1 mpp[774424]: mpp_hal: mpp_hal_init could not found coding type 7 mpp[774424]: mpp_dec: mpp_dec_init could not init hal mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp_time: mpp_clock_put invalid clock (nil) mpp[774424]: mpp: error found on mpp initialization mpp[774424]: mpi_dec_test: 0x55a962db00 mpp_init failed mpp[774424]: mpi_dec_test: test failed ret -1 mpi_dec_test[774424]: mpp_mem_pool: put_pool found 1 used buffer size 304 mpi_dec_test[774424]: mpp_mem_pool: put_pool found 4 used buffer size 224

请问要如何解决

FORGETSCHOLAR commented 2 months ago

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？

HermanChen commented 2 months ago

权限，su 之后再运行

非常感谢，问题已经全部解决
