In crossbow, each mac_srs has a kernel thread called "mac_rx_srs_poll_ring" to poll the hardware and crossbow will wakeup this thread to poll packets from the hardware automatically. Does crossbow provide any method to disable the polling mechanism, for example disabling the this kernel thread?

Team, We are trying to install Crossbow on VirtualBox. Siva first tried it on Linux and reported it in Hyderabad Open Solaris User Group alias. http://opensolaris.org/os/project/hosug/ Today both of us tried it on VirtualBox running on OpenSolaris. Both attempts have the same results. a. Selecting Solaris Developer Express during boot process exits the installation. See this picture:

Hi. After running with the crossbow bits for a while, I discovered that the network management port on my T1000 wasn''t working properly (no link light). When logging in on the serial management port and running "resetsc", I got this: --->8--- ALOM POST 1.0 Dual Port Memory Test, PASSED. TTY External - Internal Loopback Test TTY External - Internal Loopback Test, PASSED.

Howdy, I just finished reading through the Crossbow presentation: http://blogs.sun.com/sunay/resource/crossbow.pdf And have one question. If you create a virtual NIC with dladm: $ dladm create-vnic -d bge0 -m 0:1:2:3:4:5 -b 10000 1 Can you then add vnic1 directly to the zone? e.g.: zonecfg -z zone1 zonecfg:zone1> create zonecfg:zone1> set zonepath=/zones/zone1 zonecfg:zone1> a...

I recently updated to snv_125 and now bridged networks for my VirtualBox guests can''t move any network traffic. I''ve tried both VirtualBox 3.0.4 and 3.0.8 with no success. Any ideas? Thanks, Gordon -- This message posted from opensolaris.org

Recently I found that the mac_srs_rx_poll_ring thread may never stop in kernel, please see the following mpstat, cpu 2 is in 100% kernel usage, but no syscalls and no interrupts.

I''ve been thinking about hardware that has multiple transmit rings ("tx resources"). We really should have a way to expose this up to the stack. And ideally, the stack should guarantee that a given flow will always be sent down using the same hardware tx resource. I''ve heard that crossbow will deliver this, but I can''t find evidence of it in the crossbow

Hi, I maintain a driver for a 10GbE nic which supports multiple hardware tx/rx rings. We can steer rx packets into rings using the "standard" NDIS6 Toeplitz hashing on TCP port numbers, IP addresses, etc. We can also steer packets based on MAC address. Would this NIC be considered to be capable of supporting crossbow? Also, can crossbow do things like steer outgoing packets to the

I decided to take a stab at 6601421 dladm set-linkprop should support multiple -p options along with some related linkprop fixes, but when I looked into dladm.c, was surprised to find that "dladm_parse_props()" is called from do_create_aggr and do_create_vlan in addition to the expected (by me, at least) do_create_vnic *linkprop functions. What happened here? Why do we pass in

Hi everyone, I''m Ezequiel from Buenos Aires. I''m new in this list, so please forgive me if my questions are not the correct one''s fro this alias. I''m working as a campus ambassador in Sun, while finishing my engineer degree, creating communities around opensolaris in Argentina. I discovered this project, and this group, looking for something that I could

How do I create a vnic that represents the factory assigned MAC address of my physical nic? The bge device in my system (x2100) appears to support 4 MAC addresses. The driver reserves the first as the ''primary/default'' address and allows manipulation of the other three via the MAC_CAPAB_MULTIADDRESS interface. I''d like to use vnics on this system, as I have Xen guest

I read on web that llvm compiles itself with clang, but could not find the instruction to achieve that. I try "./configure CC=clang CXX=clang" but get link errors. How can I do it?

Hi. Can a virtual switch have more than one physical NIC? Or, can a VNIC have more than one NIC? (this is the same question, I think)? emike

The minimum is set at 1200Kbits/second. However, in testing, if I set that for a VNIC, the domU gets no traffic at all (maybe the occassional packet). Is the minimum too low? If I set a maximum of 2000Kbits/second, I get this from nicstat (expecting around 250Kbytes/s total: Time Int rKB/s wKB/s rPk/s wPk/s rAvs wAvs %Util Sat 04:35:38 xvm15_0 146.6 5.32 102.0
