| |
Hi,
please ignore/revert the patchset for linux/arch/i386/kernel/io_apic.c: o changed the disable_edge_ioapic_irq routine o changed level to edge handling for all IRQs that use dest_LowestPrio delivery_mode: - According to Intel Architecture Soft. Dev. Man. Vol 3, Chapter 7, Page 7-26pp: Delivery Mode 000(Fixed) Deliver ..<snip>.. The fixed interrupt is treated as an edge-triggered interrupt even if ^^^^^^^^^^^^^^^^^^^^^^^^ programmed otherwise. 001(Lowest Priority) Same as fixed mode, ..<snip>..
I missread Intel Architecture Soft. Dev. Man. Vol 3, Chapter 7, Page 7-26pp... The upper comment refers to the ICR not the IO-APIC ... so please forgive my false assumptions.
Besides that the other patches sent by me, I would like to see in the next release, cause I think they are the Right Thing (tm) .... :)
So long, Harald
