This is a list of ongoing projects, or projects that are waiting for volunteers to pick them up. USIII: Support for UltraSparc III (and higher) CPUs and their PCI bridges needs to be written. Sun4v: Support for T1000 and T2000 needs to be written. Cleanup locore.s: Locore.s needs a cleanup. KGDB: The code for kgdb needs to be fixed back up. IOMMU: The iommu code may be a performance bottleneck. This needs to be investigated. Some drivers for hardware found in sparc64 machines are still missing: floppy drive (for EBus based machines) smart card reader (found in Blade/Netra systems) environmental sensors (not really sparc64 specific) console processor (to allow (a)lom configuration from within NetBSD) We should provide bootloaders for non-ufsv1 filesystems. We could build both sparc and sparc64 libraries and allow userland (and third party/pkgsrc) programs to be build as 32bit binaries. Lots of pkgsrc software needs fixes for sparc64. Some of the assembler routines used in our libraries use registers that they should not change, according to the ABI. This is a problem for example with CLISP. Careful review is needed.
