Hi all,
I have updated my Linux Kernel to the latest. I am on Debian 64bit
3.15.5. I issue the following Kernel command line, and the vme_user
module seems to load correctly, however the vme bus is neither mounted
on /dev nor /proc.
Just to make sure, you're looking under /dev/bus/vme?
I was earlier using a 3.2 debian 32bit and managed to mount the vme
bus by following the exact same procedure of rebuilding the kernel
with vme_user module. Any help is appreciated. Here is what I see on
dmesg.
[ 0.000000] Kernel command line:
BOOT_IMAGE=/boot/vmlinuz-3.15.5-vme
root=UUID=4cdc2e84-9fbc-471c-9eb4-fde8f0b1ce96 ro vme_user.bus=0

[ 1.754948] vme_tsi148 0000:04:04.0: Enabling CR/CSR space
Cheers!
It's unfortunately going to take me a while to get everything together
to take a look, some of my old installs I've been eeking along for a
while to do adhoc VME tests are now broken :-(

Martyn,
OK. I feel like I am not clear. The kernel command line has a space,
but the line here in the email doesn't (I don't know how that
happened). I am still stuck with the same issue.
Sorry for all the confusion

Yes, copy and paste issue, I had double checked that right after I
sent you the mail. Sorry!!

I upgraded to linux kernel 3.14.9 (on Fedora). Re-compiled the kernel

Unless this is a copy and paste issue, you seem to be missing a space
between "vme_user.bus=0" and "vme_tsi148.err_chk=1".
