Hi. Maybe freebsd-hardware list would be the right place, but it's not
so active. :-(
Is 4K quirks needed for every HDDs/SSDs having physical sector size
4096?
If so, I would be able to provide patch for Crucial M550 and MX200.
(Possibly covers other models [BX200 etc.] by abstraction.)
M550(1TB): device model Crucial CT1024M550SSD1
firmware revision MU01
MX200(1TB): device model Crucial CT1024MX200SSD1
firmware revision MU03
-> Abstracted with "Crucial CT*SSD*" or "Crucial CT*", as the part
"1024" should vary with its capacity and can be 3 to 4 digits
for now. I tried the former and confirmed "quirks=0x1<4K>"
appears, which doesn't appear without adding the entry.
If not, is it sufficient if `camcontrol identify <device>` states
"physical 4096" on "sector size" line for everything in kernel and
related components (i.e., zfs-related ones)?
Regards.
