Oh I see, the point is about what's passed up as the second argument, not what device the method is invoked on. I guess then my question becomes why is the DMA tag special? We don't do this for resources, and we don't do this for the bus space tag. Is that just because normally it's virtio_pci doing the resource allocation?

How does this differ from the default implementation specified in sys/kern/bus_if.m, namely bus_generic_get_dma_tag?

how hard it would be to implement MSI interface here? to support MSI interrupts from devices, which is a crucial functionality

remove unused functions/prototypes

Indeed. I do find however that this actually fixes my issue with if_xae when tag alignment requirement for TX/RX buffers is downgraded to lower values.

Agree on using PAGE_SIZE for everyone. Most likely more controllers have this issue (even within Crucial model range), so it is a way easier to align to page_size all of them rather than deal with bug reports from users. We are a general purpose OS.
And again, Linux align to PAGE_SIZE all of them as well.

The issue arise on Crucial P310 only, so convert to a quirk

looks redundant. thanks

What I see when 32 byte requested it actually gives us PAGE_SIZE aligned address, which works.

Good points. I will check with Codasip if this is something to do with CHERI (I don't see any connection however)

Thanks @pkelsey. I will look at this once again (I did not forget about this but need to restore my CVA6 setup).
