Subject: accel/habanalabs: print max timeout value on CS stuck
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=adda800c049a4580aaec4d710a9972cdad5b14e3;p=linux.git

accel/habanalabs: print max timeout value on CS stuck

If a workload got stuck, we print an error to the kernel log about it.
Add to that print the configured max timeout value, as that value is
not fixed between ASICs and in addition it can be configured using
a kernel module parameter.
