What's the meaning of CSL

[Maxppddcsz]

When I was reading the source code related to UVM memory, I found a term “CSL context”. Could you please tell me what CSL stands for? I have searched many documents but haven’t been able to understand its meaning. Thank you very much.
`/*******************************************************************************
CSL Interface and Locking

The following functions do not acquire the RM API or GPU locks and must not be called
concurrently with the same UvmCslContext parameter in different threads. The caller must
guarantee this exclusion.

* nvUvmInterfaceCslRotateIv
* nvUvmInterfaceCslEncrypt
* nvUvmInterfaceCslDecrypt
* nvUvmInterfaceCslSign
* nvUvmInterfaceCslQueryMessagePool
* nvUvmInterfaceCslIncrementIv

*/`

CSL stands for Cryptographic Services Library.

We'll add a definition of CSL in nv_uvm_interface.h.

So what is CCSL? I found a lot of code about CCSL

[steven-bellock]

@VicoinDub It is a wrapper around the Linux Kernel Crypto API that provides cryptography services to nvidia_uvm.ko and nvidia.ko when the system is in confidential compute mode.
