In dmesg, the only QAT related message appears to be QAT: Stopping all acceleration devices. Can you confirm which QAT package is used in the host and the guest?

The Intel(R) QuickAssist Software Acceleration here likely refers to the qat_sw path of the QAT_Engine. This allows OpenSSL based applications to take advantage of additional instructions that were added to...

You are correct. This command can be used to determine if the required instructions are available: cpuid -1 | egrep 'VAES|VPCLM|GFNI|AVX512F|AVX512IFMA' Expected output: AVX512F: AVX-512 foundation instructions = true AVX512IFMA:...

You have highlighted the primary reason we do not have AES-GCM support in the LKCF - modern Xeon processors provide very good performance utilizing the AESNI instructions. Due to this,...

What is returned by the following command? lspci -nn | egrep -e '8086:37c8|8086:19e2|8086:0435|8086:6f54|8086:4940|8086:4942'

Can you provide more detail on the system configuration? What is returned by the following command? # lsmod | grep qat Is this being attempted in a guest OS? Or...

This error would be returned in the case where LacMem_OsContigAlignMemAlloc fails to allocate the requested memory. In the error log above it looks like the QAT driver fails to load....

@0xFelix - Can you share the steps that were used to configure/compile the QAT1.7 driver? Thanks, Joel

Hi Felix, Is access to QAT from kernel space required for your application? If it is not required, can you run the configure step without the --enable-kapi? Thanks, Joel

Hi Felix, You are correct - QAT kernel API support is required for ZFS. With the 5.x kernel there are changes that break the building of the module. There are...
