They (drivers) don't, but what if we start giving them routing for 64-bit DMA? AFAIU they treat 64-bit DMA as 32-bit one (according to specs: "If 64 Bit isn't an option, Silicon Backplane and PCI-E buses can use 32 bit DMA."). Won't they start using 64-bit DMA in the 32-bit way but with 64-bit routing bits? -- Rafał _______________________________________________ b43-dev mailing list [email protected] http://lists.infradead.org/mailman/listinfo/b43-dev
