[Kernel-packages] [Bug 1594455] Re: enable CRC32 and AES ARM64 by default or as module
Installed kernel and ran perf top -z while filtered on symbols containing "crc32". I see the symbol crc32c_arm64_le_hw instead of __crc32_le on hardware with CRC32 instruction support, so the change to the kernel is working. Thank you. ** Tags removed: verification-needed-xenial ** Tags added: verification-done-xenial -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1594455 Title: enable CRC32 and AES ARM64 by default or as module Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Fix Committed Bug description: The following kernel config options are disabled in linux- image-4.4.0-25-generic_4.4.0-25.44_arm64.deb and earlier.
