Why do the temperature and voltage monitor not work when the Linux* FCS driver in the 6.1.68-its branch is loaded on Agilex™ 5? - Why do the temperature and voltage monitor not work when the Linux* FCS driver in the 6.1.68-its branch is loaded on Agilex™ 5? Description Due to a problem with the FCS driver shipped in the 6.1.68-lts in QPDS24.1 release and earlier, the hwmon driver hangs when the stratix10_svc_done( ) function is executed on Agilex™ 5 device. You might see the next errors when the kernel boots and the FCS driver is loaded: [ 7.399960] svc_normal_to_secure_thread: STATUS_ERROR [56/1861] [ 7.405012] claim back P addr=0x00000000fa028024 [ 7.409854] stratix10_svc_send: fcs: sent P-va=0000000004d5ac7c, P-com=51, P-size=183056464 [ 7.418177] stratix10_svc_send: fcs: put to FIFO pa=0x0000000000000000, cmd=51, size=0 [ 7.426060] get from FIFO pa=0x0000000000000000, command=81, size=0 [ 7.432322] svc_normal_to_secure_thread: fcs: before SMC call -- a0=0x00000000c2000008 a1=0x00000000fa028038 Resolution To work around this problem, apply the following configurations: ./scripts/config --set-val CONFIG_SENSORS_SOC64 y ./scripts/config --set-val CONFIG_CRYPTO_DEV_INTEL_FCS n This problem is scheduled to be fixed in a future release of the Linux* Kernel.
