I hope that David doesn't mind my replying to his private mail in
public. My appologies if he does.
NEWCARD functionality loss:
1) Can't use ISA interrupts
2) ISA attachment currently busted (I'm working on it)
3) PCI I/O mapped cards busted (CLPD 6729)
4) No pccardd, so you must configure devices by hand.
5) Driver support compiled into kernel rather than in
/etc/pccard.conf (this could also be seen as a plus).
6) sio can't eject at the moment
7) ata seems busted (but might be busted in OLDCARD too)
8) Can't force ISA interrupts for 16-bit cards
NEWCARD adds:
1) Support for 32-bit cardbus cards
2) Automatically configures I/O and memory addresses.
3) Must *FASTER* configure times (down from 30 seconds to
under a second).
4) Multi-function 16-bit pccards more supported. This means
that many ethernet + modem cards work (but not all).
5) Ability for drivers to read the CIS (a little limited right
now).
Why now:
The Release Engineering team floated the idea of doing a
FreeBSD 5.0-DEVELOPER-PREVIEW-1 on April 1st or so and this will give
us a month of more intensive testing before that. There will be a
DP-2 release in June. June seems too long to wait.
