Jeff,
From the below link (from Sergei) it seems that you have already
re-factored the AHCI implementation dependency on PCI. I would like to
add support for the OMAPL138 SATA on top of your changes. That would
be the ideal way forward for me.
Have the ahci re-factoring changes queued for mainline merge already?
I just joined the list and hence do not know the status.
Sergei,
Appreciate the response.
I store the refactoring in git, on the "libahci" branch of
git://git.kernel.org/pub/scm/linux/kernel/git/jgarzik/libata-dev.git
Unfortunately, I am having second thoughts about an element of the
current design. With current Linux distributions, they do not appear to
deal well with the multi-module dependency libata -> libahci -> ahci. If
I had to guess, I would say that mkinitrd creation tools only look at
one tree level's worth of kernel module dependencies.
Thus, ahci would wind up -not- in initrd, in a libahci solution.
I am thinking that I will just add Marvell and ATP support to ahci.c,
and let someone else deal with libahci separation -- which is still needed.
At this point, I would rather get Marvell/ATP support into users' hands,
rather than wait for distros to catch up to modern technology.
If that's the case it seems clearly a mkinitrd bug. What distribution
were you seeing this behavior on?
