I thought it might be interesting to forward the message below to
current_at_ .  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

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)

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
