Hello, My name is Dee Sharpe.? I am currently researching the *BSD agpgart driver as well as the one from Linux and any other OS's driver that I can find.? From reading the source code agp.c, it seems as though agp_generic_bind_memory() allocates memory from the OS.? Why is this the case?? Shouldn't this function be solely focused on binding the memory that is provided in the agp_memory structure?? Also, shouldn't agp_generic_alloc_memory() be the only part of the driver that worries about memory allocation?? I am asking these questions out of interest and I'm looking for understanding, because I would like to port your driver to Syllable.? Syllable has a relatively primitive memory management system, so a lot of the techniques used by the *BSD OS's will not be usable by us.? Also, any help or guidance that you can give me to help me bring this driver to life is greatly appreciated. -Dee Sharpe P.S.? This email was sent to mailing lists belonging to FreeBSD, OpenBSD, and NetBSD.
