drm/tegra: Add job firewall Add a firewall that validates jobs before submission to ensure they don't do anything they aren't allowed to do, like accessing memory they should not access. The firewall is functionality-wise a copy of the firewall already implemented in gpu/host1x. It is copied here as it makes more sense for it to live on the DRM side, as it is only needed for userspace job submissions, and generally the data it needs to do its job is easier to access here. In the future, the other implementation will be removed. Signed-off-by: Mikko Perttunen <mperttunen@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com> 2021-06-10 14:04:55 +03:00
