2009-01-07Add a -net name=foo parameter (Mark McLoughlin)aliguori1-1/+1
Allow the user to supply a vlan client name on the command line. This is probably only useful for management tools so that they can use their own names rather than parsing the output of 'info network'.

2009-01-07Add a model string to VLANClientState (Mark McLoughlin)aliguori1-2/+2
Don't lose track of what type/model a vlan client is so that we can e.g. assign a global per-model id to clients. The entire patch is basically a tedious excercise in making sure the type/model string gets propagated down to qemu_new_vlan_client().

2008-12-09KVM: Coalesced MMIO supportaliguori1-0/+12
MMIO exits are more expensive in KVM or Xen than in QEMU because they involve, at least, privilege transitions. However, MMIO write operations can be effectively batched if those writes do not have side effects. Good examples of this include VGA pixel operations when in a planar mode. As it turns out, we can get a nice boost in other areas too. Laurent mentioned a 9.7% performance boost in iperf with the coalesced MMIO changes for the e1000 when he originally posted this work for KVM.

2008-11-21e1000 VLAN offload emulation (Alex Williamson)aliguori1-7/+73
We're currently ignoring the e1000 VLAN tagging, stripping and filtering features in the e1000 emulation. This patch adds backing for the relevant registers and provides a software implementation of the acceleration, such that a guest can make use of VLANs. This is mostly (only?) useful for a guest on a bridge (not user mode networking). The only caveat beyond that is that you need to make sure the host NIC isn't doing it's own tagging, stripping, or filtering. This generally means the host NIC on the bridge should not be part of a VLAN.

2008-08-06only check RCTL_EN in e1000_can_receive()aliguori1-2/+1
e1000_receive() has code to raise a receive overflow interrupt when the receive buffer head and tail match. However, with the present implementation of e1000_can_receive(), this code is unreachable -- and etherboot breaks as a result.

2008-03-13e1000: fix endianness issuesaurel321-7/+16
This patch fixes endianness issues in the e1000 nic emulation, which currently only works on little endian hosts with little endian targets. Byte swapping does not depend on host endianness, so this patch remove the use of cpu_to_le32 and le32_to_cpu functions. It depends on the path from the CPU to the device, which is currently and *wrongly* implemented in Qemu as a byteswap on big endian targets. This patch does the same as in other devices emulation as all the currently implemented targets work with this implementation. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4046 c046a42c-6fe2-441c-8c8c-71466251a162
