| * | | | vga: fix bochs alignment issueGerd Hoffmann2012-11-162-3/+3
| | |/ / | |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bochs dispi interface traditionally uses port 0x1ce as 16bit index register and port 0x1cf as 16bit data register. The later is unaligned, and probably for that reason the the data register was moved to 0x1d0 for non-x86 archs. This patch makes the data register available at 0x1d0 on x86 too. The old x86 location is kept for compatibility reasons, so both 0x1cf and 0x1d0 can be used as data register on x86. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the MIPS Malta Developement Platform User's Manual, the i8259 interrupt controller is supposed to be connected to the hardware IRQ0, and the CBUS UART to the hardware interrupt 2. In QEMU they are both connected to hardware interrupt 0, the CBUS UART interrupt being wrong. This patch fixes that. It should be noted that the irq array in QEMU includes the software interrupts, hence env->irq[2] is the first hardware interrupt.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes use of the new level irqfd support enabling bypass of qemu userspace both on INTx injection and unmask. This significantly boosts the performance of devices making use of legacy interrupts (ex. ~60% better netperf TCP_RR scores for an e1000e assigned to a Linux guest and booted with pci=nomsi). This also avoids flipping mmaps on and off to simulate EOIs, so greatly improves performance of device access in addition to interrupt latency.
