Ubuntu disables Intel GPU security mitigations, promises 20% performance boost
This is fine for single user systems. If your system allows more than 1 users, this is probably not something you want to do.
The point is the Linux Kernel is covering the same security mitigations which make the CPU level ones redundant. If all users are using the Linux Kernel, why would it be an issue?
Depends on how you use your system if you have multiple users. CPU mitigations wont protect GPU workloads, and vice versa. If your CPU was mitigating GPU workloads, that would probably be a massive performance loss.
Or if you run untrusted code. Including code that might be susceptible to a compromised developer or a supply chain attack.
Or you use a web browser
I read in another comment about this that the safeguards in the kernel would still remain. The hardware just wouldn't do it by itself.
The kernel mitigations would be for the CPU, not the GPU.
