OK, but now that I've tried it, the vpfe_capture driver in 2.6.28 doesn't seem to support USERPTR I/O. It doesn't look like the latest version of vpfe_capture does, either. And yet, using MMAP I/O is broken because CMEM can't translate the mmap'd addresses... surely this is not the state of affairs; what have I overlooked?
probably nothing, it might be the case with the kernel/driver you have.
Were you allocating the buffers via CMEM from within the driver? That will work for my situation, probably, but that seems like a nasty depedency to create from a kernel development standpoint.
No, CMEM buffers allocated by the app, but this is on ye olde 2.6.10 Davinci kernel and might have had some fixes to make userptr work (have to check) _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
