font-family:Arial'>I’m working a project using a Spartan 6 FPGA with a
PCIe interface and MSI interrupts. I want to use multiple MSI interrupts
(MSI-X is not supported in the FPGA PCIe core) but the current Linux
distribution (3.0.8) prevents that (lines 23 to 25 in arch/powerpc/kernel/msi.c).<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>What’s the story here? Is the code in place but
not tested? I tried commenting out those lines but a request_irq() called
failed for the second interrupt requested. Am I wasting my time
here? Should I re-architect to use a single MSI interrupt?<o:p></o:p></span></font></p>
