I tracked down the exception happens at part_test_efi()->block_dread() function:
if (!ops->read) return -ENOSYS;
Where ops points to nowhere, because underlying SATA device does not have a DM driver associated.
Could you please fix this?
I've been hoping that someone else will take on this side of things, but perhaps I am optimistic. I'll see if I can take a look.
Thanks. I wanted to fix this myself however I have been busy on some other stuff.
I've sent a series which I think puts SCSI and SATA in a better position with respect to driver model. However even with that there is more work to do.
Thanks for working on this! I will take a look.
If we don't get enough time to sort out everything, we will have to revert previous MMC DM conversion patch and leave that to next release.
Yes, let's see how it goes. I probably have time for one more spin if it is soon...but the last patch needs work.
As Andreas has pointed out here:
https://lists.denx.de/pipermail/u-boot/2017-June/296337.html
SCSI seems to be broken also on Armada 37xx (and perhaps other platforms as well). Is it correct to assume, that this x86 SCSI thread is about the same issue?
I know that you are working on DM SCSI support, which is great of course. But do you have an idea, if and how this could be fixed for this upcoming release?
Thanks, Stefan
