2011-05-05CPUPhysMemoryClient: Pass guest physical address not region offsetAlex Williamson1-4/+12
When we're trying to get a newly registered phys memory client updated with the current page mappings, we end up passing the region offset (a ram_addr_t) as the start address rather than the actual guest physical memory address (target_phys_addr_t). If your guest has less than 3.5G of memory, these are coincidentally the same thing. If there's more, the region offset for the memory above 4G starts over at 0, so the set_memory client will overwrite it's lower memory entries. Instead, keep track of the guest phsyical address as we're walking the tables and pass that to the set_memory client. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-05-05CPUPhysMemoryClient: Fix typo in phys memory client registrationAlex Williamson1-1/+1
When we register a physical memory client, we try to walk the page tables, calling the set_memory hook for every entry. Effectively playing catchup for the client for everything already registered. With this type, we only walk the 2nd entry of the l1 table, typically missing all of the registered memory. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S.

2011-05-05eepro100: Fix endianness issuesStefan Weil1-44/+97
Like other Intel devices, e100 (eepro100) uses little endian byte order. This patch was tested with these combinations: i386 host, i386 + mipsel guests (le-le) mipsel host, i386 guest (le-le) i386 host, mips + ppc guests (le-be) mips host, i386 guest (be-le) mips and mipsel hosts were emulated machines. v2: Use prefix for new functions. Add the same prefix to stl_le_phys. Fix alignment of mem (needed for word/dword reads/writes). Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2011-05-05eepro100: Pad received short framesStefan Weil1-1/+25
QEMU sends frames smaller than 60 bytes to ethernet nics. Such frames are rejected by real NICs and their emulations. To avoid this behaviour, other NIC emulations pad received frames. This patch enables this workaround for eepro100, too. All related code is marked with CONFIG_PAD_RECEIVED_FRAMES, so we can drop this in case QEMU's networking code is ever changed.

2011-05-05eepro100: Remove unused structure elementStefan Weil1-3/+3

2011-05-04usb: control buffer fixesHans de Goede2-1/+7
Windows allows control transfers to pass up to 4k of data, so raise our control buffer size to 4k. For control out transfers the usb core code copies the control request data to a buffer before calling the device's handle_control callback. Add a check for overflowing the buffer before copying the data. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-04usb-linux: Add support for buffering iso out usb packetsHans de Goede1-51/+101

2011-05-04usb-linux: We only need to keep track of 15 endpointsHans de Goede1-3/+3
Currently we reserve room for endpoint data for 16 endpoints, but given that we only use endpoint data for endpoints 1-15, and always index the array with the endpoint-number - 1, 15 is enough. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-04usb-linux: Refuse iso packets when max packet size is 0 (alt setting 0)Hans de Goede1-1/+5
Refuse iso usb packets when then max packet size for the endpoint is 0, this avoids an abort in usb_host_alloc_iso() caused by trying to qemu_malloc a 0 bytes large buffer.
2011-05-04usb-linux: Refuse packets for endpoints which are not in the usb descriptorHans de Goede1-0/+13
If an endpoint is not in the usb descriptor we've no idea what kind of endpoint it is and thus how to handle it, refuse packages in this case. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-04usb-linux: Add support for buffering iso usb packetsHans de Goede1-17/+226
Currently we are submitting iso packets to the host one at a time, as we receive them from the emulated host controller. This has 2 problems: 1) If we were fast enough to submit every packet in time for the next host host controller usb frame, we would be generating 1000 hardware interrupts per second on the host 2) We are not fast enough to submit every packet in time for the next host host controller usb frame, causing us to not submit iso urbs in some usb frames which causes devices with an endpoint with an interval of 1 ms (so every frame) to loose data. This causes for example ubs-1.1 webcams to not work properly (usb-2.0 is not supported at all atm). This patch fixes both problems by changing the iso packet pass through handling to buffer packets. This version only does so for iso input packets (webcams, audio in) I'm working on a second patch extending this to iso output packets (audio out). This patch makes use of the linux batching of iso packets in one urb. When an iso in packet gets received from the emulated host controller, it immediately submits 3 urbs with 32 iso in packets each. This causes the host to only get an hw interrupt every 32 packets dropping the interrupt rate to 32 interrupts per second and gives it a queue of urbs to work from once the first 32 iso in packets have been received to make sure no packets are dropped. Besides submitting a whole bunch or urbs as soon as the first urb is received, effectively creating a buffer inside the kernel, this patch also gets rid of the asynchroneous completion for iso in urbs. Instead they are only marked as complete in the fd write callback (which usbfs uses to signal complete urbs). These complete packets then get consumed by returning them synchroneously to the emulated host controller when it submits an iso in packet for the ep in question. When no complete packets are ready (which happens when the stream is starting) a 0 length packet gets returned to the emulated host controller. With this patch I've several usb-1.1 webcams working well with usb pass through, where as without this patch none of them work. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-04usb-linux: Get the alt. setting from sysfs rather then asking the devHans de Goede1-0/+18
At least one device I have lies when receiving a USB_REQ_GET_INTERFACE, always returning 0 even if the alternate setting is different. This is likely caused because in practice this control message is never used as the operating system's usb stack knows which alternate setting it has told the device to get into, and thus this ctrl message does not get tested by device manufacturers. When usb_fs_type == USB_FS_SYS, the active alt. setting can be read directly from sysfs, which allows using this device through qemu's usb redirection. More in general it seems a good idea to not send needless control msg's to devices, esp. as the code in question is called every time a set_interface is done. Which happens multiple times during virtual machine startup, and when device drivers are activating the usb device. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
2011-05-04usb-linux: introduce a usb_linux_alt_setting functionHans de Goede1-15/+25
The next patch in this series introduces multiple ways to get the alt setting dependent upon usb_fs_type, it is cleaner to put this into its own function. Note that this patch also changes the assumed alt setting in case of an error getting the alt setting to be 0 (a sane default) rather then the interface numberwhich makes no sense.

2011-05-03spice: drop obsolete iothread lockingGerd Hoffmann2-14/+0
We don't use qemu internals from spice server context any more. Thus we don't also need to grab the iothread mutex from spice server context. And we don't have to temporarely release the lock to avoid deadlocks. Drop all the calls. Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
