    SubjectRe: Write-combining

    Have I missed something here?

    Am I being dim?

    Or is the usual "instant advice" feature switched off?


    The device I am writing the driver for formally didn't support
    write-combining and it took
    10000 clock ticks to do a partial transfer- now it does support
    write-combining and it still
    takes 10000 clock ticks to transfer the data- It is performance
    critical- How do I switch
    write-combining on? It is worth at least a 2x speed up for me?

    If it is something obvious please don't be afraid to point it out-----

    Thanks SA
