With shipping charges from the US (to the UK) it costs $130, which these days is around 92 UK pounds, but hopefully the price will drop as suggested in this article: http://www.t3.com/news/marvell-sheevaplug-hides-a-computer-in-a-plug-socket?=38234 and shipping charges should come down as and when it is stocked by European distributors. Shipping charges are divised by two if you buy two plugs at once, so finding another hacker nearby should help a lot :). Playing with shipping costs to France: $31 shipping for 1 plug, $16/plug for 2, $14/plug for 5, $9/plug for 15, $4.36/plug for 48, ask for 75 plug I added the SheevaPlug kindly donated by Marvell to the GCC Compile Farm which is open to all free software developpers (not limited to GCC), instructions on how to get an account here: http://gcc.gnu.org/wiki/CompileFarm Up to now the farm was more oriented toward upstream userspace compile/test/debug development but if there's a need for kernel developers to be able to reboot on new kernels, access to serial console, power cycle, etc... we can try to work out a solution. Playing around with bzip2 -dc, the 1200 MHz kirkwood is like a 700 MHz P3, a 500 MHz opteron (32 bits) or 400 MHz opteron (64 bits), and genrally when compiling and running various software between two and three time faster than the Thecus N2100 XScale-80219 running at 600 Mhz.

We are very interested in data throughput, could you please post some very basic ethernet performace numbers? My main concern so far has been to get a working kernel image into the archive as soon as possible, so I haven't had a chance to look at performance yet. What kind of test would you like to see? Basic test from the plug gcc55 to my PC pc2: gcc55 ~ # iperf -c pc2 -N -n 1000M Client connecting to pc2, TCP port 5001 TCP window size: 16.0 KByte (default) [ 3] local 192.168.1.118 port 45282 connected with 192.168.1.101 port 5001 [ 3] 0.0-51.5 sec 1000 MBytes163 Mbits/sec My PC has: 02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller [10ec:8168] (rev 02) Note: the plug was running two compilations by farm users during the network test and the kernel has lock checking enabled so it's unlikely an upper bound :).

Hi, Thanks to two new patches queued for git://git.marvell.com/orion.git idle consumption is significantly improved in my setup: 2.3W Idle with everything unpluged 3.3W Idle with gigabit ethernet 5.0W Idle with gigabit+HDD USB+serial 7.0W +100% cpu cos phi is in the 0.5 range. When cpu is loaded but not completely the power usage should also be lower but it's harder to measure in my setup. powertop 1.11 report on a mostly idle system: Cn Avg residency C0 (cpu running)( 0.0%) C09.8ms ( 0.5%) C1 402.7ms (99.6%) Kernel config options to enable: CONFIG_NO_HZ=y CONFIG_TIMER_STATS=y CONFIG_CPU_IDLE=y CONFIG_CPU_IDLE_GOV_LADDER=y CONFIG_CPU_IDLE_GOV_MENU=y Also on the performance front: a native kernel compile from scratch with Gentoo 4.1.2 p1.3 GCC takes around 50 minutes.

Hi, You could try to open a project on powerdevelopper.org: http://www.powerdeveloper.org/ They have an arm board donation program to developpers: http://projects.powerdeveloper.org/program/imx515 They gave boards to the compile farm so the program is real :).
