Return to TODO CVS log

Up to [local] / sys / ntfs

Import of OpenBSD 4.2 release kernel tree with initial code to support 
Jornada 720/728, StrongARM 1110-based handheld PC.
At this point kernel roots on NFS and boots into vfs_mountroot() and traps.
What is supported:
- glass console, Jornada framebuffer (jfb) works in 16bpp direct color mode
(needs some palette tweaks for non black/white/blue colors, i think)
- saic, SA11x0 interrupt controller (needs cleanup)
- sacom, SA11x0 UART (supported only as boot console for now)
- SA11x0 GPIO controller fully supported (but can't handle multiple interrupt
handlers on one gpio pin)
- sassp, SSP port on SA11x0 that attaches spibus
- Jornada microcontroller (jmcu) to control kbd, battery, etc throught
the SPI bus (wskbd attaches on jmcu, but not tested)
- tod functions seem work
- initial code for SA-1111 (chip companion) : this is TODO

Next important steps, i think:
- gpio and intc on sa1111
- pcmcia support for sa11x0 (and sa1111 help logic)
- REAL root on nfs when we have PCMCIA support (we may use any of supported pccard NICs)
- root on wd0! (using already supported PCMCIA-ATA)

- convert the code to do caching in buffer cache indexed by
  file-vnode/file-offset so that NTFS would take advantage of UBC;
  it should also improve performance somewhat, because if it's necessary
  to find some offset in a file, it's possible to check if the data
  are available in the cache before doing the bmap operation first
	(from Chuq)

- working VOP_BALLOC() (new in UBC)
	(from Chuq)

- readdir: evaluate impact of using variable length reclen - should
  enable us to store much more entries into buf in typical case with
  short filenames, though more work would need to be done in offset != 0
  case

- readdir: fill in proper "inode" number for '..' entry

- handle Unicode filenames more inteligently - they are translated to UTF-2
  form currently, adding hooks for various character sets or other encodings
  would be trivial

- implement writing into resident attributes, so it would be possible
   to write into "small" files (<30KB) too
	(from Semen Ustimenko <semenu@FreeBSD.org>)
  generally, better write support

- once writing would work, consider quota support

- support mount update

- really implement sync

- write necessary bits to support NTFS in libsa

- NTFS ACL support (though usefullness of such feature is arguable)
