  • 3bd391f05   crypto: Add support for x86 cpuid auto loading for x86 crypto drivers ... Browse Code »

    Add support for auto-loading of crypto drivers based on cpuid features.
    This enables auto-loading of the VIA and Intel specific drivers
    for AES, hashing and CRCs.

    Requires the earlier infrastructure patch to add x86 modinfo.
    I kept it all in a single patch for now.

    I dropped the printks when the driver cpuid doesn't match (imho
    drivers never should print anything in such a case)

    One drawback is that udev doesn't know if the drivers are used or not,
    so they will be unconditionally loaded at boot up. That's better
    than not loading them at all, like it often happens.

  • 8cb51ba8e   crypto: crc32c - Use Intel CRC32 instruction ... Browse Code »

    From NHM processor onward, Intel processors can support hardware accelerated
    CRC32c algorithm with the new CRC32 instruction in SSE 4.2 instruction set.
    The patch detects the availability of the feature, and chooses the most proper
    way to calculate CRC32c checksum.
    Byte code instructions are used for compiler compatibility.
    No MMX / XMM registers is involved in the implementation.
