    SubjectRe: [PATCH v3, 00/15] Using component framework to support multi hardware decode
    From
    Date
    Thank you for the patchset.

    Could you provide information on how you
    tested the code.
    Did you test it on chromeos userspace?
    Did you use the test-tast framework?
    What tests did you run?

    Dafna
