I thought it might be interesting to forward the message below to
current@ . I have made a version of the patch for CURRENT 2006-11-13
available at
http://home.tiscali.nl/rladan/freebsd/xtaf-head-20061113.diff.bz2
-rw-r--r-- 1 rene rene 40867 13 nov 22:34 xtaf-head-20061113.diff.bz2
MD5 (xtaf-head-20061113.diff.bz2) = b8be64e1331470a1153965dc0903d085
It survives 'make buildworld' and 'make buildkernel', it probably
doesn't properly hook up to /dev yet (see below).
If you want to play with the code, you'd better take a dd of your
precious Xbox stuff... (i.e. no warranty)

Rene

Hi,
I've uploaded a new version of the XTAF (XBox 360 fs) code at
http://home.tiscali.nl/rladan/freebsd/xtaf-r6-20061112.diff.bz2
The code now patch(1)es against /usr/src, no further actions are needed
as in the previous version. It compiles on RELENG_6 2006-11-12, it
probably fails on CURRENT.
Read support should be fairly complete. Some hard disk issues may be
remaining, but memory cards should be supported unless I made a mistake
somewhere. I haven't really looked into write support yet.
The biggest todo right now is to connect the code with the code which
creates /dev/da?s? (geom?) . Both memory cards and hard disks have
multiple slices. The start/size information is not stored on the
devices, but in the XBox 360 kernel, so we have to duplicate it here.
For memory cards (64MB) :
start size info
0x0 0x7ff,000 XTAF, 16 bits, system cache
0x7ff,000 0x3,621,000 XTAF, 16 bits, user area
For hard disks (20GB) :
start size info
0x0 0x80,000 hard disk header
0x80,000 0x80,000,000 XTAF, 16 bits, system cache
0x80,080,000 0xA0,E30,000 unused, filled with 00
0x120,eb0,000 0x10,000,000 XTAF, 16 bits, XBox 1 compatibility
0x130,eb0,000 0x377,680,000 XTAF, 32 bits, user area
I haven't yet looked at the new 256MB memory cards (goto shop). There
are also rumors about larger hard disks, ranging from 60GB to 200GB.
Other todos: write support, hard disk header support
Could some locking / fs guru could sanity check the code? That would
speed up runtime testing of the code.
Regards,
Rene
