the following patch was just integrated into master: commit cf18c856aafaaa2a7e5eaebf64a2d5c647e590e8 Author: Jonathan A. Kollasch jakllsch@kollasch.net Date: Fri Oct 11 16:14:18 2013 -0500
ck804: hide IOAPIC base address in PCI_BASE_ADDRESS_1
Linux unhelpfully "fixes" the value in PCI_BASE_ADDRESS_1 when it is 0xfec00000 (that is, outside the range of bus 0 address space). This causes IOAPIC interrupts to fail to work under Linux. This issue was originally unnoticed by me when testing as sanity checking such as this is not done by NetBSD.
Hiding the IOAPIC BAR is done by the OEM BIOS on the ck804 boards I've checked.
