 Posted: Mon Jul 10, 2023 6:17 pm Post subject: ccp_crypto: Cannot load: there are no available CCPs |
 |
|
Before I compiled my new kernel, "lspci -k -nn" returned | Code: | 0b:00.1 Encryption controller [1080]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Cryptographic Coprocessor PSPCPP [1022:1486]
Subsystem: ASUSTeK Computer Inc. Starship/Matisse Cryptographic Coprocessor PSPCPP [1043:8808] |
The driver was not compiled into the old kernel.
After consultation with Hardware for Linux, I enabled the kernel options CONFIG_CRYPTO, CONFIG_CRYPTO_DEV_CCP and CONFIG_CRYPTO_DEV_CCP_DD CONFIG_PCI. Now, "lspci -k -nn" returns
| Code: | 0b:00.1 Encryption controller [1080]: Advanced Micro Devices, Inc. [AMD] Starship/Matisse Cryptographic Coprocessor PSPCPP [1022:1486]
Subsystem: ASUSTeK Computer Inc. Starship/Matisse Cryptographic Coprocessor PSPCPP [1043:8808]
Kernel driver in use: ccp |
However, at boot time I get the error | Code: | [ 4.282201] ccp 0000:0b:00.1: enabling device (0000 -> 0002)
[ 4.282258] ccp 0000:0b:00.1: ccp: unable to access the device: you might be running a broken BIOS.
[ 4.282273] ccp 0000:0b:00.1: psp enabled
[ 4.282277] ccp_crypto: Cannot load: there are no available CCPs |
What does this error mean? How do I fix it? The error is somewhat annoying, because it interrupts the boot splash screen before X starts and SDDM appears. Should I remove the driver again, if it is broken anyway?

Have you enabled IOMMU (for AMD) in your kernel configuration ?
Do you have a working ccp (= without any error in dmesg) if you boot with a LiveUbuntu ?
If no, it could be a problem with your BIOS.
If yes, you might do:
1. Save the output from "lspci -k" AND "lsmod" (from Ubuntu),
2. Compare it to your (complete) "lspci -k" AND "lsmod" from your system.
If you find something missing you should update your kernel configuration. If you will need help for this, then:
Give us all 4 outputs AND your latest kernel .config (please use wgetpaste for this). |

Just compiled Kernel-6.13.0 and found the same message:
| dmesg: | Feb 01 13:05:05 nixe kernel: ccp 0000:12:00.2: enabling device (0000 -> 0002)
Feb 01 13:05:05 nixe kernel: ccp 0000:12:00.2: tee enabled
Feb 01 13:05:05 nixe kernel: ccp 0000:12:00.2: psp enabled
Feb 01 13:05:05 nixe kernel: ccp_crypto: Cannot load: there are no available CCPs |
But for some reason it seems to work:
| lspci -knn: | 12:00.2 Encryption controller [1080]: Advanced Micro Devices, Inc. [AMD] Family 19h PSP/CCP [1022:1649]
Subsystem: ASUSTeK Computer Inc. Device [1043:8877]
Kernel driver in use: ccp |
Kernel config:
| Code: | CONFIG_CRYPTO_DEV_CCP=y
CONFIG_CRYPTO_DEV_CCP_DD=y
CONFIG_CRYPTO_DEV_SP_CCP=y
CONFIG_CRYPTO_DEV_CCP_CRYPTO=y
CONFIG_CRYPTO_DEV_SP_PSP=y |
@nagmat84: Have a look to: https://wiki.gentoo.org/wiki/Gigabyte_X570-UD#CPU
