Starting with commit 1c380f94 dma transfers can actually fail. This patch makes ehci keep track of the busmaster bit in pci config space, by setting/clearing the dma_context pointer. Attempts to dma without context will result in raising HSE (Host System Error) interrupt and stopping the host controller. This patch fixes WinXP not booting with a usb stick attached to ehci. Root cause is seabios activating ehci so you can boot from the stick, and WinXP clearing the busmaster bit before resetting the host controller, leading to ehci actually trying dma while it is disabled.

While testing the move to async packet handling for interrupt endpoints I noticed that Windows-XP likes to play tricks with the next pointer for periodic qh-s, so we should not fail qh / qtd verification when it changes.

Windows links interrupt qtd-s in circles, which means that when interrupt endpoints return USB_RET_ASYNC, combined with the recent "ehci: Retry to fill the queue while waiting for td completion" patch, we keep adding the tds to the queue over and over again, as we detect the circle from fill_queue, but we call it over and over again ... This patch fixes this by changing the circle detection to also detect circling into tds already queued up previously.

This avoids the q->qtdaddr == p->qtdaddr asserts we have triggering, when a queue contains multiple completed packages when we cancel the queue. I triggered this with windows7 + async interrupt endpoint handling (*) + not detecting circles in ehci_fill_queue() properly, which makes the qtd validation in ehci_fill_queue fail, causing cancellation of the queue on every mouse event ... *) Which is not going upstream as it will cause loss of interrupt events on migration.

The Linux is more tolerant here as well: Just stop parsing the device descriptors when an error is detected but do not reset what was found so far.

Commit a844ed84 leads to usb-host detecting devices not right after qemu startup because the guest isn't running yet. Instead they are found on the first of the regular usb device poll runs. Which is too late for seabios to see them, so booting from usb sticks fails. Fix this by adding a vm state change handler which triggers a device scan when the vm is started.

Elements in qemu SGLists can cross IOMMU page boundaries. So, in commit 39c138c8 "usb: Fix usb_packet_map() in the presence of IOMMUs", I changed usb_packet_map() to split up each SGList element on IOMMU page boundaries and each resulting piece of qemu's memory space separately to the iovec the usb code uses internally. That was correct in concept, but the patch has a bug. The 'base' variable correctly steps through the dma address of each piece, but then we call the dma_memory_map() function on the base address of the whole SGList element every time. This patch fixes at least one problem using XHCI on the pseries guest machine. It didn't affect OHCI because that doesn't use usb_packet_map(). In theory it also affects EHCI, but we haven't observed that in practice. I think the transfers were small enough on EHCI that they never crossed an IOMMU page boundary in practice.

Commit 1c380f94 breaks live migration. DMA stops working for ehci (and probably for any pci device) after restoring the guest because the bus master region never gets enabled.

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.
