Rebecca Cran	01688065e7	Document the fact that passing in a count of zero to the bus_space functions ... will result in undefined behaviour. Taken from NetBSD's bus_space(9).	2010-12-03 18:30:55 +00:00
Rebecca Cran	c90f7d9b44	Revert r216134. This checkin broke platforms where bus_space are macros: ... they need to be a single statement, and do { } while (0) doesn't work in this situation so revert until a solution can be devised.	2010-12-03 07:09:23 +00:00
Rebecca Cran	15b4888a24	Disallow passing in a count of zero bytes to the bus_space(9) functions. ... Passing a count of zero on i386 and amd64 for [I386|AMD64]_BUS_SPACE_MEM causes a crash/hang since the 'loop' instruction decrements the counter before checking if it's zero.

Ruslan Ermilov	a3a57e81b3	Correct the list of bus_space_*_stream_[1248] functions in the ... STREAM FUNCTIONS section: - Really list only and all *_stream_* functions. - Don't list their arguments (it's pointless).	2006-09-18 14:31:03 +00:00

Warner Losh	751c35718a	Don a flack jacket and start to document the FreeBSD bus_space ... implementation. I took the NetBSD man page, and hacked it to, I hope, to reflect the preliminary version of the bus space that Justin Gibbs committed as part of the CAM integration in FreeBSD 3.0. This isn't perfect, but it is better than we have now (which is, ahem, nothing). Please coordinate changes to the file through me through the 6.0 release.
