Hi,
I'm trying to control the GPU's HVS module by writing directly to memory. An approach to this is described here - https://blog.benjdoherty.com/2019/05/21 ... splay-List - though in my case I plan do it via /dev/mem since I'm using Linux.
I can't find any documentation on the HVS's registers or glean anything (other than a handful of addresses for the scaling settings) from the Linux source: https://github.com/torvalds/linux/blob/ ... vc4_regs.h.
The best I can do via the pseudo filesystems is:
which gives me the following:
So clearly there's quite a lot to map.
Can anyone offer any help?
Thanks.
