I seem to recall that we were talking about trying to drop the debounce delay for
everything, weren't we?
So perhaps it would be right to add a 4th patch in the series to do just that. Then
If this turns out to be problematic for anything other than the controllers in the
series that you identified as not problematic then that 4th patch can potentially
be reverted alone?
Not quite everything :) But you are right, let's try to switch the default
to no delay. I will be posting patches today for that.
Paul,
With these patches, your patches are not necessary anymore as the AMD
chipset falls under the default no-delay.
I am all for improving the situation for all devices, but I am unable to
judge the regression potential of changing this, as it affects a lot of
devices. I guess it’d would go through the next tree, and hopefully the
company QA teams can give it a good spin. I hoped that my patches, as I
have tested them, and AMD will hopefully too, could go into the current
merge window.
Yes, correct, the plan is to get the generic series queued as soon as rc1
so that it can spend plenty of time in linux-next for people to test. That
will hopefully reduce the risk of breaking things in the field. Same for
the default LPM change.
But 5.18 or 5.19? If 5.18, sounds good to me, if 5.19, I’d be great if
my patches go into 5.18 cycle, as they have been tested, and it would
mean the whole change gets tested more widely already.
With the default removal of the debounce delay, your patches addressing
only the AMD adapter are not needed anymore: this adapter will not have a
debounce delay unless the ATA_LFLAG_DEBOUNCE_DELAY flag is set.
Yes, I understand.
It would be nice if you can test though.
Of course, I am going to that either way.
Series posted with you on CC. Please test !
Thank you. I am going to test it in the coming days, and report back.
Maybe more people should be put in Cc (Dell, Lenovo, IBM, x86 subsystem)
with a request to test this?
Kind regards,
Paul
