NVIDIA Accelerated Linux/IA64 Driver Set README Last Updated: 2004/01/20 Most Recent Driver: 1.0-5336 This document contains information specific to the Linux/IA64 version of the NVIDIA Accelerated Driver Set. It is intended as an addendum to the file README, not as a substitute. The file README contains general information about the NVIDIA Accelerated Driver Set. This includes sections on proper installation procedure and troubleshooting hints. Supported Chipsets: The following chipsets are supported: Quadro, Quadro2 MXR, Quadro2 EX, Quadro2 Pro, Quadro DCC, Quadro4 550 XGL, Quadro4 750 XGL, Quadro4 900 XGL, Quadro FX 500, Quadro FX 1000, Quadro FX 2000 and Quadro FX 3000. Requirements: The NVIDIA Accelerated Linux/IA64 Driver Set requires Linux kernel version 2.4.13 or later. Earlier kernel versions had ACPI problems that prevent our driver from receiving interrupts from the graphics chip. However, kernel version 2.6 and later will not work properly. Revert to a 2.4-series kernel, or upgrade to a newer driver or patch if one is available. AGP Support: This driver release has full AGP support using the Linux kernel's AGPGART driver. NVIDIA's internal NVAGP driver is not supported on IA64. Setting the XFree86 option NvAgp to 1 (use NVAGP) will not work. PCI-based DMA is supported, setting the XFree86 option to NvAgp to 0 (no AGP) will work. If you are using Linux/ia64 2.4.18-ia64-020226, a change made in the AGPGART implementation requires a one line change in the implementation of KernMapAGPNopage (os-agp.c): -phys_addr = agp_memory_ptr->memory[idx]; +phys_addr = (agp_memory_ptr->memory[idx] & 0xffffff) << 12; If you are using a different kernel and are seeing kernel OOPSes in KernMapAGPNopage, you may also need to make this change. Known Issues in 1.0-5336: The following IA64-specific problems still exist in this release and are in the process of being resolved. o The Quadro 900XGL is known not to work reliably with Red Hat Enterprise Linux version 2.1, including update 3. Please upgrade your copy of Red Hat Enterprise Linux to 3.0 or later. o The Quadro FX1000, FX2000 and FX3000 are known to have problems when used in zx2000 and zx6000 computers. NVidia recommends testing for stability before deploying Quadro FX GPUs in zx2000 or zx6000 machines.
