Here you will find information on the current state of the development effort. It will be updated periodically and will give you a snapshot of the current state of Linux on the PA-RISC.

CURRENT TO DO LIST

February 28, 2001

Kernel

• rewrite semaphores -- both read/write and ordinary (Matthew)
• Create an IO tree to support multiple I/O MMUs. (Ryan)
• SuperIO Serial (Martin Petersen and Alex deVries)
• fix fbcon-sti.c bugs and X11? (David)
• Kernel Memory dumps on crash. See SGI's LKCD. (Bruno Vidal?)
• HIL keyboard driver needs updating (Brian and Alex has access to HIL documentation)
• Coalesce DMA pages in sba_map_sg() (Grant)
• Coalesce DMA pages in ccio_map_sg() (Ryan)
• LASI Floppy controller (Dave Kennedy)
• WAX EISA bus addapter (Alex deVries)
• Harmony audio driver completion (Alex deVries)
• AD1889 PCI Audio driver (Alex deVries)
• SMP support
  • build/test w/CONFIG_SMP (ggg)
  • Interrupt Distribution (even CPU loading) w/CONFIG_SMP (ggg)
  • asm-parisc/cache.h defines L1_CACHE_BYTES - issue w/32-bit on PA2.0 (ggg)
• 64-bit kernel
  • VM (John)
  • PA2.0 Hand-Tuned/Optimised asm IP checksum code (Randolph)
  • Syscalls/ioctl (John, Paul, George, Ringo, Cast of Thousands)
  • defconfig and friends
  • check/fix sim700 driver compile warnings (needed to support Cxxx boxes in wide mode, if we ever want to) (Ryan)
  • 64-to-32-bit translator for PDC firmware calls on Cxxx boxen (enable more people to test wide kernels) (Ryan)
  • Change 'unsigned long sversion:28' to unsigned int in hardware.h?
    Change hardware.c functions which take hversion/sversion args?
  • Do the right thing with macro elf_check_arch() for wide/narrow kernels (see include/asm-parisc/elf.h)
  • Fix 'hwclock' problem (probably a broken or missing ioctl32.c translation).
• Kernel debugger - KWDB (Grant)
• Fix cache/TLB flushing. (John)
• Finish ptrace(2) implementation. (Thomas)
• Unaligned trap handler. (Volunteer?)
• Finish floating point completion and trap handler. (Volunteer?)
• Verify floating point trap behaviour is correct (Volunteer?)
• Remove kbd_read_status() dependency on CONFIG_GSC_PS2. (Volunteer?)
• <include/asm-parisc/types.h> defines dma_addr_t as 32-bit. PCI/Elroy supports 64-bit. "typedef ulong_t dma_addr_t"? (Volunteer?)
• Update Documentation/parisc/registers (Volunteer?)
• PA1.1 SR can be 16-32 bits wide - only using 16-bits. (Volunteer?)
• rewrite kernel_thread (Matthew)
• Dino/100BT: Use "Good Dog" Timer to limit GSC bus tenancy instead of limiting tulip DMA burst length. (Volunteer?)
  (JSM has tried this - it didn't work. GGG thinks it should.)
• remove asm-parisc/real.h fixing dependencies on it
• Verify and fix the existing code in led.c for LCD displays (Volunteer?)

Userland

• Test/Debug floating point environment support in GNU libc. (Volunteer?)
• Debug floating point environment and trap handling. (Volunteer?)
• Write open version of required 64-bit libmilli routines. (Volunteer?)
