The current generation of Intel® QuickAssist Technology devices are not designed to run in an untrusted environment because of the following issues reported in the release notes in https://01.org/intel-quickassist-technology: QATE-39220 - GEN - Intel® QAT API submissions with bad addresses that trigger DMA to invalid or unmapped addresses can cause a platform hang QATE-7495 - GEN - An incorrectly formatted request to Intel® QAT can hang the entire Intel® QAT Endpoint This patch adds the following QAT devices to the blocklist: DH895XCC, C3XXX and C62X.
