Add a Platform::setup_irq_mode function which enables the IRQ session to update the trigger mode and polarity of the associated IRQ according to the session parameters. On ARM this function is a nop. This change enables the x86_64 platform to support devices which use arbitrary trigger modes and polarity settings, e.g. AHCI on QEMU and real hardware. Fixes #1528. |
