23 /* I think it would be in everyone's best interest to follow this
24 * guidelines when writing PDC wrappers:
26 * - the name of the pdc wrapper should match one of the macros
27 * used for the first two arguments
28 * - don't use caps for random parts of the name
29 * - use the static PDC result buffers and "copyout" to structs
30 * supplied by the caller to encapsulate alignment restrictions
31 * - hold pdc_lock while in PDC or using static result buffers
32 * - use __pa() to convert virtual (kernel) pointers to physical
34 * - the name of the struct used for pdc return values should equal
35 * one of the macros used for the first two arguments to the
36 * corresponding PDC call
37 * - keep the order of arguments
38 * - don't be smart (setting trailing NUL bytes for strings, return
39 * something useful even if the call failed) unless you are sure
40 * it's not going to affect functionality or performance
