This will never happen right now (the assertion would fail). The next patch will set the socket or pipe in non-blocking mode, thus enabling this part of the code. Coroutines can just stop whenever they want with qemu_coroutine_yield. As soon as select tells the main loop that the migration stream is readable, the coroutine is re-entered directly in qemu_get_buffer, where it will read more data and pass it to the loading routines.

migrate_fd_cleanup will usually close the file descriptor via buffered_file_close's call to migrate_fd_close. However, in the case of s->file == NULL it is "inlining" migrate_fd_close (almost: there is a direct close() instead of using s->close(s)). To fix the inconsistency and clean up the code, allow multiple calls to migrate_fd_close and use the function in migrate_fd_cleanup. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

This fixes the following: target-i386/cpu.o: In function `kvm_cpu_fill_host': target-i386/cpu.c:783: undefined reference to `kvm_state' I didn't notice the problem before because GCC was optimizing the entire kvm_cpu_fill_host() function out (because all calls are conditional on kvm_enabled()). * cpu_x86_fill_model_id() is used only if CONFIG_KVM is set, so #ifdef it entirely to avoid compiler warnings. * kvm_cpu_fill_host() should be called only if KVM is enabled, so use #ifdef CONFIG_KVM around the entire function body.

To avoid continually having to bump the initrd load address to account for larger kernel images, put the initrd halfway through RAM. This allows large kernels on new boards with lots of RAM to work OK, without breaking existing usecases for boards with only 32MB of RAM. Note that this change fixes in passing a bug where we were passing an overly large max_size to load_image_targphys() for the initrd, which meant that we wouldn't correctly refuse to load an enormous initrd that didn't actually fit into RAM.

This follows the logic of host-linux: If a 2.0 device has no ISO endpoint and no interrupt endpoint with a packet size > 64, we can attach it also to an 1.1 host controller. In case the redir server does not report endpoint sizes, play safe and remove the 1.1 compatibility as well. Moreover, if we detect a conflicting change in the configuration after the device was already attached, it will be disconnected immediately.

Older versions (anything but the latest) of Linux usbfs + libusb(x), will submit larger (bulk) transfers split into multiple 16k submissions, which means that rather then all tds getting linked into the queue in one atomic operarion they get linked in a bunch at a time, which could cause problems if: 1) We scan the queue while libusb is in the middle of submitting a split bulk transfer 2) While this bulk transfer is pending we migrate to another host. The problem is that after 2, the new host will rescan the queue and combine the packets in one large transfer, where as 1) has caused the original host to see them as 2 transfers. This patch fixes this by stopping combinging if we detect a 16k transfer with its int_req flag set. This should not adversely effect performance for other cases as: 1) Linux never sets the interrupt flag on packets other then the last 2) Windows does set the in_req flag on each td, but will submit large transfers in 20k tds thus never triggering the check Signed-off-by: NHans de Goede <hdegoede@redhat.com> Signed-off-by: NGerd Hoffmann <kraxel@redhat.com>

Currently we only do pipelining for output endpoints, since to properly support short-not-ok semantics we can only have one outstanding input packet. Since the ehci and uhci controllers have a limited per td packet size guests will split large input transfers to into multiple packets, and since we don't pipeline these, this comes with a serious performance penalty. This patch adds helper functions to (re-)combine packets which belong to 1 transfer at the guest device-driver level into 1 large transger. This can be used by (redirection) usb-devices to enable pipelining for input endpoints. This patch will combine packets together until a transfer terminating packet is encountered. A terminating packet is a packet which meets one or more of the following conditions: 1) The packet size is *not* a multiple of the endpoint max packet size 2) The packet does *not* have its short-not-ok flag set 3) The packet has its interrupt-on-complete flag set The short-not-ok flag of the combined packet is that of the terminating packet. Multiple combined packets may be submitted to the device, if the combined packets do not have their short-not-ok flag set, enabling true pipelining. If a combined packet does have its short-not-ok flag set the queue will wait with submitting further packets to the device until that packet has completed. Once enabled in the usb-redir and ehci code, this improves the speed (MB/s) of a Linux guest reading from a USB mass storage device by a factor of 1.2 - 1.5. And the main reason why I started working on this, when reading from a pl2303 USB<->serial converter, it combines the previous 4 packets submitted per device-driver level read into 1 big read, reducing the number of packets / sec by a factor 4, and it allows to have multiple reads outstanding. This allows for much better latency tolerance without the pl2303's internal buffer overflowing (which was happening at 115200 bps, without serial flow control).

My recent uhci cleanup series has introduced a regression, where qemu sometimes crashes on a device disconnect. The problem is that the uhci code never checked for a device not / no longer existing, instead it was relying on usb_handle_packet accepting a NULL device. But since we now pass usb_handle_packet q->ep->dev, rather then just a local dev variable, we crash as q->ep == NULL due to the device no longer existing. This patch fixes this. Note that this patch also improves over the old behavior were we would: 1) create a queue for the device 2) create an async for the packet 3) have usb_handle_packet fail 4) destroy the async 5) wait for the queue to be idle for 32 frames 6) destroy the queue Which was rather sub-optimal.
