send_event() hook will allow to send ACPI event in a target specific way (GPE or GPIO based impl.) it will also simplify proxy wrappers in piix4pm/ich9 that access ACPI regs and SCI which are part of piix4pm/lcp_ich9 devices and call acpi_foo() API directly. Signed-off-by: Igor Mammedov <imammedo@redhat.com> --- Following patch will use hook to simplify hotplug callbacks in piix4pm/ich9. --- hw/acpi/core.c | 2 +- hw/acpi/piix4.c | 8 ++++++++ hw/isa/lpc_ich9.c | 8 ++++++++ include/hw/acpi/acpi.h | 10 ++-------- include/hw/acpi/acpi_dev_interface.h | 18 ++++++++++++++++++ 5 files changed, 37 insertions(+), 9 deletions(-)
