NVIDIA Accelerated Linux/IA64 Driver Set README Last Updated: $Date: 2001/08/20 $ Most Recent Driver: 1.0-2880 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, Quadro 2 MXR, Quadro 2 EX, Quadro 2 Pro, Quadro DCC, and Quadro 4 XGL. 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 interupts from the graphics chip. 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. Known Issues in 1.0-2880: The following IA64 specific problems still exist in this release and are in the process of being resolved. o OpenGL/X may occassionaly generate "floating point assist faults" and unaligned data access faults. When running OpenGL application you may see ... unaligned access to 0xXXXXXXXXXXXXXXXX, ip=0xXXXXXXXXXXXXXXXX ... floating-point assist fault at ip XXXXXXXXXXXXXXXX printed to the system log. Its not yet clear if these are application faults, OpenGL faults or some combination thereof.
