Hi, thanks a lot for the fast response!!!! 1. it is v2.4 2. ``` $ modinfo nvidia filename: /lib/modules/4.15.0-213-generic/updates/dkms/nvidia.ko firmware: nvidia/525.105.17/gsp_tu10x.bin firmware: nvidia/525.105.17/gsp_ad10x.bin alias: char-major-195-* version: 525.105.17 supported: external license:...
1. I run it again. Here is the result: ``` $ ./gdrcopy_sanity -v -t data_validation_cumemalloc &&&& RUNNING data_validation_cumemalloc buffer size: 327680 Allocated GPU memory at 0x7f04f1000000 DBG: sse4_1=1 avx=1 sse=1...
Hi, I checked the dmesg: ``` [114826.509844] gdrdrv:gdrdrv_open:minor=0 filep=0xffff8aed944e4f00 [114826.509848] gdrdrv:gdrdrv_ioctl:ioctl called (cmd 0xc008daff) [114826.509858] gdrdrv:gdrdrv_ioctl:ioctl called (cmd 0xc028da01) [114826.509859] gdrdrv:__gdrdrv_pin_buffer:invoking nvidia_p2p_get_pages(va=0x7f04f1000000 len=327680 p2p_tok=0 va_tok=0) [114826.509920] gdrdrv:__gdrdrv_pin_buffer:page table entries: 5...
Hi, I already set it to passthrough since I am using the RDMA with amd cpu. This is required by RDMA previously. ``` $ dmesg|grep iommu [ 0.000000] Command line:...
Hi there, I further did some tests based on that I can only use GPUDirect RDMA with `size H`, as long as I add a `usleep(0.01);` in function `void init_hbuf_walking_bit(uint32_t...
Hi @pakmarkthub, Thanks so much for your advice. Yes, I found that the GPUDiretct RDMA can work and I have not checked whether the data is corrupted. I will continue...
