The split IRQ chip mode via KVM_CAP_SPLIT_IRQCHIP was introduced with commit 15eafc2e60 but was broken for q35. This patch makes kernel_irqchip=split functional for q35. Signed-off-by: Rita Sinha <rita.sinha89@gmail.com> --- hw/i386/pc_q35.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
