The Linux qla1280 v3.23 driver as distributed in the IA-64 patch *always* sets a 64-bit dma_mask if running on a 64-bit processor. The NVRAM bit isn't read as the switch anymore. #if BITS_PER_LONG > 32 /* Enable 64bit addressing for OS/System combination supporting it */ /* actual NVRAM bit is: nv->cntr_flags_1.enable_64bit_addressing */ /* but we will ignore it and use BITS_PER_LONG macro to setup for */ /* 64 or 32 bit access of host memory in all x86/ia-64/Alpha systems */ ha->flags.enable_64bit_addressing = 1; #else ha->flags.enable_64bit_addressing = 0; #endif #if LINUX_VERSION_CODE >= KERNEL_VERSION(2,3,18) if (ha->flags.enable_64bit_addressing) { printk("[[[ qla1x160: 64 Bit PCI Addressing Enabled ]]]\n"); #if BITS_PER_LONG > 32 /* Update our PCI device dma_mask for full 64 bit mask */ //ha->pdev->dma_mask = (pci_dma_t) 0xffffffffffffffffull; ha->pdev->dma_mask = 0xffffffffffffffff; #endif } #endif Jes cleaned this up a bit with his patch: + pci_set_dma_mask(ha->pdev, (dma_addr_t)~0ULL); Thanks, Matt -- Matt Domsch Sr. Software Engineer Dell Linux Solutions www.dell.com/linux > -----Original Message----- > From: Wiegrefe, Don J [mailto:don.j.wiegrefe@intel.com] > Sent: Tuesday, May 22, 2001 5:34 PM > To: 'Michael Madore'; Matt_Domsch@exchange.dell.com > Cc: linux-ia64@linuxia64.org > Subject: RE: [Linux-ia64] 2.4.4 stability on Lions > > > While it is true you should always use the latest BIOS that > matches your > processor stepping ( in this case 76 ).
