On T234 theCTXSW LS ucodes are encrypted. ACR will perform the decryption and the decrypted content will be written back into the same WPR location. So on recovery with LSPMU absence and on warm boot case, to perform the authentication , the ucode blob needs to be copied into the WPR from sysmem always. Below are the LS ucodes authentication type * LSPMU - Only Signed ( Only for non-safety build, for safety LSPMU is NA) * CTXSW FECS/GPCCS - Encrypted and Signed (on both safety and non-safety build) ACR FW P4 Change : 32110924 JIRA NVGPU-7903 Change-Id: If447148c02b9cf310102cfb9c688eef402699409 Signed-off-by: Dinesh Kamalakannan <dineshka@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nvgpu/+/2822656 Reviewed-by: svc-mobile-coverity <svc-mobile-coverity@nvidia.com> Reviewed-by: svc-mobile-cert <svc-mobile-cert@nvidia.com> Reviewed-by: svc-mobile-misra <svc-mobile-misra@nvidia.com> Reviewed-by: Vaibhav Kachore <vkachore@nvidia.com> GVS: Gerrit_Virtual_Submit <buildbot_gerritrpt@nvidia.com>
