Hi, I recently do some experiments with the global data share(GDS). I wrote a kernel that simply writes some contents into GDS starting from address 0 using ds_write instructions.
The question is how to read the contents using PM4 packets without launch a "read kernel".
I have tried PACKET3_COPY_DATA and PACKET3_DMA_DATA, but these packets will hang and never return.
I was wondering if it is possible to read GDS using PM4 packets.
