Updates on 8/5 codebase:
- Hot insertion/removal of my modem works fine as much as I try it. I
did it a half-dozen times.
- Hot insertion/removal of my ethernet *mostly* works fine. I can do
it 3-4 times, and then it'll hang on removal.
Updates on 8/7 codebase:
- Hot insertion/removal of my modem still works fine as much as I try it.
- Hot removal of my ethernet card hangs the box almost everytime.
Also, insertion/removal events were not recognized after one reboot,
but that may have been my issue. (Is polling used in this version?
How do I check?
- pccardc power [0|1] 0 (explicitly powering it down before removal)
allows me to remove the ethernet card w/out a hang.
The changes I suspect are:
imp 2001/08/06 07:47:45 PDT
Modified files: (Branch: RELENG_4)
sys/pccard pcic.c i82365.h
Log:
MFC: Power off again and preserve some bits in PCIC_INT_GEN
also, minor #define shuffle.
Approved in principle by: jkh
Revision Changes Path
1.89.2.17 +3 -3 src/sys/pccard/pcic.c
1.10.2.4 +2 -2 src/sys/pccard/i82365.h
[ The change to i82365.h is essentially a no-op ]
If I revert *only* these changes from my kernel, hot-swap ethernet works
better. (But it's still not as good as I'd like).
[
Note, my modem isn't being used *at all* during this process, so I
wouldn't expect there to be any problems with hot-swap. My ethernet
is also unused, but I suspect the ethernet drivers are still active
even when nothing is connected.
