sparc64 and amr LSILogic MegaRAID 1.53

[Andreas Tobler]

Hello,

I wonder if the amr(4) driver should work on sparc64. I see in the 
GENERIC that amr is commented. Is this due to not working anymore, or is 
this entry just an artifact and the driver did never work?

I have here a HP NetRAID-1Si PCI card and tried the amr driver. The 
first try failed due to amr calling bus_dma_tag_create with a NULL as 
first argument. Fixing this gets me some steps further with a frozen 
machine w/o bt.

Hangs, hardreset here.

My question, is this amr(4) driver in its current implementation thought 
to work on sparc64, or is it only for LE systems?

If it was working once, I'm interested to get it back working, well just 
for learning purpose.

TIA,

Andreas
