Re: svwsata: lost/missing interrupt

[Michael <macallan1888%gmail.com@localhost>]

Hello,

I dimly remember doing some changes on svwsata in order to make it work
properly on macppc ( all G5 macs have an svwsata onboard ).
Symptoms were interrupt storms, the solution was to make sure to use
32bit accesses when reading the (8bit) status register, apparently
there's some hardware bug this works around.
There were other G5-specific fixes, all went in around June 2018, just
before the 8.0 release, so they were probably not pulled up.
Makes me wonder if any of those have adverse side effects on non-macppc.

have fun
Michael
