Hello,
Good day. My inquiry is about block drivers. Suppose our device
encounter problems and all error handling failed. The only remaining
option I see for the driver to do is to offline it. The intention is
for the system to be notified to avoid sending any future request to
the device and b
I'm having a problem where the server system hosting a pci device
we're developing messes up in boot and can't get to the login screen.
I'm developing a linux driver for that pci device (a block device/ssd
actually). However from our tests, when the device is has undergone
lots of usage, it initia
Hello,
In my pci driver for a certain pci device, I implemented the pci error
handler functions (error_detected, slot_reset methods, etc). I want
to trigger a pci error for me to exercise those handlers and observe
its behavior. I've read from the pci error recovery kernel
documentation that the
I see. Thanks Greg! Just posted to the mailing list you mentioned.

Hello Gurus,
I'm currently creating a Linux driver for block devices. This has been
going on for some time, and I just recently changed the driver design from
bio-mode to request-mode (I used to handle struct bio but now I'm operating
on struct request) and it made the functionality simpler, bu
Hello Pranay,
Thanks for your very helpful insights! I hope you don’t mind if I continue
with more questions on block layer :-)

Hello Pranay!
Thanks for your reply. I apologize for my very late reply, I was very
preoccupied earlier at work.
