ServeRAID M5210e passthroughand syspd corruption

[Borja Marcos]

Hello,

I'm trying to make this card work. As  I am going to use ZFS, I need it in passthrough mode. However, both in 10-STABLE and 11-CURRENT
it's corrupting data.

The card is detected as follows:
mfi0: <Invader> port 0x4f00-0x4fff mem 0x913f0000-0x913fffff,0x91400000-0x914fffff irq 34 at device 0.0 on pci22

And according to mfiutil,
root at merde:/home/borjam # mfiutil show adapter
mfi0 Adapter:
    Product Name: ServeRAID M5210e
   Serial Number: XXXXX
        Firmware: 24.0.2-0013
     RAID Levels: JBOD, RAID0, RAID1, RAID10
  Battery Backup: not present
           NVRAM: 32K
  Onboard Memory: 0M
  Minimum Stripe: 64K
  Maximum Stripe: 64K


Curiously, other mfi cards which don't officially support syspd mode work in passthrough without problems. And indeed
mfisyspd is not adequate to use SSDs. It's much better to use passthrough and the "da" driver.

Is there any download I can try for the "mrsas" driver to test under FreeBSD 10 and 11? I'd like to know if mrsas can
make it work properly.

Also, I am wondering. Is it possible that syspd support in the driver may have caused trouble? I was considering purging it and
try again.


Thanks!




Borja.
