we have guys who maintain xml descriptions of all Blackfin processors. these include an exhaustive list of all the peripherals and their MMRs. for example, there is an element that binds the address, the MMR name (as described in the processor's hardware manual), the bit size of it, and all those fun details. i feed these xml files through an xsl to generate a C file that populates /sys/kernel/debug/blackfin/ by using the standard debugfs functions. so when i'm debugging the watchdog driver, i can simply go into /sys/kernel/debug/blackfin/watchdog/ and see the watchdog-specific MMRs and cat/echo them on the fly. it's been quite handy and feedback from customers/developers is that it's nicely filled a small void in the development process.
the trouble is that this file currently weighs in at ~1.8 megs. this is because it contains all the information for all Blackfin processors we support (which currently, is about ~23 variants). it's only going to get bigger as we support more. Bryan cringes at the thought of submitting it to LKML :). so i'm fishing around for alternatives ... the code was originally developed against 2.6.21, so UIO was not a possibility. i'm still not sure if it is ... i'd have to research it a bit more and play with things. any pointers ? -mike -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
