I was hoping that I would see buffers which are mapped beyond the 4G physical addr (i.e > 32-bit) if I have HIGHMEM enabled and use apps that make use of "sendfile" for Zero-copy (like in pure-ftpd) on a IA-32 machine. However my pci_map_page for the buffer seems to have the upper-32 bits all 0's. Is there something I am missing w/regard to HighMem operation? or is there a better test app that I can use? > > BTW my test machine setup has 5GB of RAM running a 2.4.16 HIGHMEM enabled kernel. > > Would appreciate any responses or pointers... > -Sanjay > -- > __________________________________________________________ > Sign-up for your own FREE Personalized E-mail at Mail.com > http://www.mail.com/?sr=signup > > Save up to $160 by signing up for NetZero Platinum Internet service. > http://www.netzero.net/?refcd=N2P0602NEP8 > > -- > To unsubscribe, send a message with 'unsubscribe linux-mm' in > the body to majordomo@kvack.org.
