2014-02-24opencores_eth: flush queue whenever can_receive can go from false to trueMax Filippov
The following registers control whether MAC can receive frames: - MODER.RXEN bit that enables/disables receiver; - TX_BD_NUM register that specifies number of RX descriptors. Notify QEMU networking core when the MAC is ready to receive frames. Discard frame and raise BUSY interrupt when the frame arrives but the current RX descriptor is not empty.

acpi,pci,pc,virtio fixes and enhancements This includes new unit-tests for acpi by Marcel, hotplug for pci bridges by myself (piix only so far) and cpu hotplug for q35. And a bunch of fixes all over the place as usual. I included the patch to fix memory alignment for q35 as well - even though it limits 32 bit guests to 3G (they previously could address more memory with PAE). To remove the limit, this will have to be fixed in seabios. I also added self as virtio co-maintainer so I don't need to troll the list for patches to review. Signed-off-by: Michael S.

2014-01-27Fix lan9118 buffer length handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch uses the provided buffer length to limit the bytes transmitted. Previously all the bytes of the last 32-bit word written to the TX fifo were added to the internal transmit buffer structure resulting in more bytes being transmitted than were submitted to the hardware in the command. This resulted in extra bytes being inserted into the middle of multi-buffer packets when the non-final buffers had non-32bit aligned ending addresses.

2014-01-27Fix lan9118 TX "CMD A" handlingRoy Franz
The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch changes the buffer size and offset internal state variables to be updated on every "TX command A" write. Previously they were only updated for the first segment, which resulted incorrect behavior for packets with more than one segment. Each segment of the packet has its own CMD A command, with its own buffer size and start offset. Also update extraction of fields from the CMD A word to use extract32().

2013-12-24hw: cannot_instantiate_with_device_add_yet due to pointer propsMarkus Armbruster
Pointer properties can be set only by code, not by device_add. A device with a pointer property can work with device_add only when the property may remain null. This is the case for property "interrupt_vector" of device "etraxfs,pic". Add a comment there. Set cannot_instantiate_with_device_add_yet for the other devices with pointer properties, with a comment explaining why. Juha Riihimäki and Peter Maydell deserve my thanks for making "pointer property must not remain null" blatantly obvious in the OMAP devices. Only device "smbus-eeprom" is actually changed. The others are all sysbus devices, which get cannot_instantiate_with_device_add_yet set in their abstract base's class init function. Setting it again in their class init function is technically redundant, but serves as insurance for when sysbus devices become available with device_add, and as documentation.

2013-11-21Revert "e1000/rtl8139: update HMP NIC when every bit is written"Michael S. Tsirkin
This reverts commit cd5be5829c1ce87aa6b3a7806524fac07ac9a757. Digging into hardware specs shows this does not actually make QEMU behave more like hardware: There are valid arguments backed by the spec to indicate why the version of e1000 prior to cd5be582 was more correct: the high byte actually includes a valid bit, this is why all guests write it last. For rtl8139 there's actually a separate undocumented valid bit, but we don't implement it yet. To summarize all the drivers we know about behave in one way that allows us to make an assumption about write order and avoid spurious, incorrect mac address updates to the monitor. Let's stick to the tried heuristic for 1.7 and possibly revisit for 1.8.

We currently just update the HMP NIC info when the last bit of macaddr is written. This assumes that guest driver will write all the macaddr from bit 0 to bit 5 when it changes the macaddr, this is the current behavior of linux driver (e1000/rtl8139cp), but we can't do this assumption. The macaddr that is used for rx-filter will be updated when every bit is changed. This patch updates the e1000/rtl8139 nic to update HMP NIC info when every bit is changed. It will be same as virtio-net.
