It probably means falling through to the "fake an EOI for line level interrupt code", as the Status bit is RO in the IO-APIC (The IRR bit is RW but both need updating) Does anyone know which revision of the IO-APIC was the first with an EOI register? If not, I think I have some document trawling to do. >> I'd also like you to add 23820:ba75234a6f56 ("bitmap_scnlistprintf() >> should always zero-terminate its output buffer") to 4.0 (I see it's >> already in 4.1), as this not being fixed confuses 'e' debug key output. > Ok. > > -- Keir > >> Jan >> > -- Andrew Cooper - Dom0 Kernel Engineer, Citrix XenServer T: +44 (0)1223 225 900, http://www.citrix.com
