2013-12-09virtio-net: don't update mac_table in error stateAmos Kong1-15/+20
mac_table was always cleaned up first in handling VIRTIO_NET_CTRL_MAC_TABLE_SET command, and we din't recover mac_table content in error state, it's not correct. This patch makes all the changes in temporal variables, only update the real mac_table if everything is ok. We won't change mac_table in error state, so rxfilter notification isn't needed. This patch also fixed same problame in http://lists.nongnu.org/archive/html/qemu-devel/2013-11/msg01188.html (not merge) I will send patch for virtio spec to clarifying this change.

2013-11-21Revert "e1000/rtl8139: update HMP NIC when every bit is written"Michael S. Tsirkin2-2/+5
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.

2013-11-06e1000/rtl8139: update HMP NIC when every bit is writtenAmos Kong2-5/+2
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.

2013-09-06e1000: add interrupt mitigation supportVincenzo Maffione1-3/+128
This patch partially implements the e1000 interrupt mitigation mechanisms. Using a single QEMUTimer, it emulates the ITR register (which is the newer mitigation register, recommended by Intel) and approximately emulates RADV and TADV registers. TIDV and RDTR register functionalities are not emulated (RDTR is only used to validate RADV, according to the e1000 specs). RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation mechanism and would need a timer each to be completely emulated. However, a single timer has been used in order to reach a good compromise between emulation accuracy and simplicity/efficiency. The implemented mechanism can be enabled/disabled specifying the command line e1000-specific boolean parameter "mitigation", e.g. qemu-system-x86_64 -device e1000,mitigation=on,... ... For more information, see the Software developer's manual at http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf. Interrupt mitigation boosts performance when the guest suffers from an high interrupt rate (i.e. receiving short UDP packets at high packet rate).
