NVIDIA Accelerated Linux/IA64 Driver Set README Last Updated: $Date: 2001/08/20 $ Most Recent Driver: 1.0-3127 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 and Quadro4 900 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. If you are using Linux/ia64 2.4.18 (-ia64-020410 or later), a change made in the AGPGART implementation requires a one line change in the implementation of KernMapAGPNopage (os-interface.c): -phys_addr = (agp_memory_ptr->memory[idx] & 0xffffff) << 12; +phys_addr = agp_memory_ptr->memory[idx]; If you are using a different kernel and are seeing kernel OOPSes in KernMapAGPNopage, you will also need to make this change. Known Issues in 1.0-3127: 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.
