Qualcomm QCE Driver On The Chopping Block With ~48x Slower Than Armv8 Crypto Extensions
Qualcomm QCE Driver On The Chopping Block With ~48x Slower Than Armv8 Crypto Extensions Written by Michael Larabel in Linux Security on 24 July 2026 at 02:45 PM EDT. Add A Comment A few days back I wrote about upstream Linux kernel developers marking the Qualcomm crypto accelerator driver as "broken" and "harmful" due to its slow performance, history of bugs, and other limitations. Now this Qualcomm Crypto Engine "QCE" driver might be removed outright from the Linux kernel source tree after discovering it's even worse than anticipated.

Add A Comment A few days back I wrote about upstream Linux kernel developers marking the Qualcomm crypto accelerator driver as "broken" and "harmful" due to its slow performance, history of bugs, and other limitations. Now this Qualcomm Crypto Engine "QCE" driver might be removed outright from the Linux kernel source tree after discovering it's even worse than anticipated. Linux kernel crypto expert Eric Biggers of Google is looking to remove the Qualcomm QCE driver outright and just not simply gate it behind the "BROKEN" Kconfig knob.
