Subject: [9fans] ata vs. ide
Date: Thu, 12 Feb 2009 15:04:07 -0500	[thread overview]
Message-ID: <607437dca1767cfbee4d759c5b6a2a62@quanstro.net> (raw)

there's a little confusion with ata vs. ide.  the short
2008 story is that ata is a command set, ide is a
programming interface.  the history is much more
complicated and riddled with backronyms like
“pata.”

so i think it would be a good idea to at least
make this change in sd(3)

; diffy -c sd
/n/dump/2009/0212/sys/man/3/sd:21,36 - sd:21,39
  .IR C  ,
  and by its unit number
  .IR u .
- The controller naming convention for ATA(PI) units starts
- with the first controller being named
+ The controller naming convention for legacy IDE units
+ names the first controller
[etc.]

i realize that it might be excessively annoying to
change sdata.c to sdide.c, but even if that is too
much i still think it would be a good idea to clarify
things in the man page. after all, the ahci and mv50xx
drivers also use the ata command set.

objections?
