Look at > PLATFORM_INTERRUPT_SOURCE, fields Polarity and TriggerMode. The platform interrupt source tells to which I/O APIC (and which pin) special platform interrupts are connected. The only interrupt sources that can be described are PMIs (or SMIs in ia32 slang), INITs or CPEIs (Corrected Platform Error Interrupts). It is and cannot be used for generic interrupts, so it will not have the information we need for an UART interrupt source (the case I had to hardcode). I want to know if the default trigger mode and polarity for ACPI defined devices is fixed or predefined... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe p4-projects" in the body of the message
