Part Number: J721EXCPXEVM
Hello,
I am researching the GPU accelerator on the J721E. I have downloaded the Technical Reference Manual and and looked into the Linux PowerVR Driver. I have two questions:
1. The TRM contains a register map for the PBIST feature of the GPU (part 2, section 5), but has little to no information beside listing the register names and addresses. Where can I find more details?
2. The Linux DRM refers to a mapping of registers controlling the GPU itself. While I understand information about those should be requested to Imagination directly, I was curious about where this mapping started in the J721E memory, as the TRM only describes the PBIST block in relation to the GPU.
Thank you for the assistance.
