| 00:18.23 | ManoftheSea | so... if the hardware design is done by a different company... |
| 00:18.39 | ManoftheSea | and they don't have software expertise... |
| 00:19.20 | ManoftheSea | I don't really understand who the company luke is talking to is. |

| 01:13.21 | hipboi | mnemoc: hi |
| 01:13.43 | hipboi | mnemoc: sorry for so long time |
| 01:14.54 | hipboi | mnemoc: finally they agreed to sell the community A10 dev kit pro at a reasonable price |
| 01:15.01 | hipboi | mnemoc: 250 USD |
| 01:31.44 | A2Sheds | lets start a collection and get a kit |
| 01:32.07 | A2Sheds | hipboi: can we order a tray of CPU's to go along with it? |
| 02:39.07 | hipboi | A2Sheds: i don't know about the cpu samples, i think you can contact eva |
| 02:43.26 | A2Sheds | ok, will do |
| 02:47.05 | A2Sheds | hipboi: do you know how long you will close down for Chinese New Year? |
| 04:13.30 | hipboi | it depends |
| 04:14.53 | hipboi | the Chinese new year is 1.23 - 1.30 |
| 08:20.44 | mnemoc | moin, I just replied eva asking how to pay for the kit, I hope I get one shipped before new year |
| 12:41.26 | ManoftheSea | mnemoc: this is why I want to understand how to clean up the code, by understanding the code. |
| 12:43.53 | mnemoc | ManoftheSea: it seems to me that the 1.5GHz is not the cortex-a8 core, but the mali gpu |
| 13:05.10 | ManoftheSea | hmm... but the speed boost over the 700MHz next chip was a really big feature. |
| 13:05.17 | ManoftheSea | why do you think it's the gpu? |
| 13:05.33 | ManoftheSea | It looks like the "core clock" can go up to 1.48, or so... |
| 13:05.50 | ManoftheSea | But is only limited by that define, pegging at 1.008 |
| 13:34.46 | mnemoc | ManoftheSea: no real reason just a feeling |

| 13:54.24 | mnemoc | ManoftheSea: at http://www.slatedroid.com/topic/25116-1ghz-12ghz-15ghz-which-is-it/ they suggest 1.5 comes from adding the 1 from the cpu with 0.5 from the gpu |
| 14:00.04 | ManoftheSea | the slate does run at 1.008 |
| 14:00.21 | ManoftheSea | as the code we can get is to be for the slate, and is limited at 1.008 |
| 14:00.35 | ManoftheSea | that's the fastest it can go at 1.4V |
| 14:03.46 | mnemoc | I hope to be able to buy the devkit soon |
| 14:07.14 | gordan | Well, there's always overclocking. :) |
| 14:07.34 | gordan | If the clock generators and multiplers can handle it, along with the voltage regulators being adjustable enough. |
| 14:07.47 | gordan | I've achieved +40% on Tegra2. |
| 14:50.04 | gordan | http://www.reghardware.com/2012/01/06/lenovo_introduces_hybrid_thinkpad_x1_with_intel_qualcomm_chips/ |
| 14:50.13 | gordan | I wonder if it'd actually run without an Intel CPU... |
| 15:45.38 | ManoftheSea | ew, a multi-proc, multi-arch laptop? |
| 15:46.35 | ManoftheSea | and ridiculous expensive? |
| 15:56.02 | gordan | Well, if it'll work without the Intel processor, it's pretty much what I've been hoping for - a decent laptop with an ARM in it. :) |
| 15:56.30 | gordan | Depends on how you can use the ARM processor on it and if the machine still relies on the x86 CPU to bootstrap it. |
| 16:36.01 | mnemoc | do you see realistic to think a 11-12" laptop of the construction quality of the thinkpads but with cortex-a9 will be available in the next 2y? |
| 16:36.17 | mnemoc | s/of/with/ |
| 16:36.26 | mnemoc | ibot: thank you |
| 16:36.26 | ibot | mnemoc: de rien |
| 16:36.40 | mnemoc | :D |
| 16:38.00 | mnemoc | (or better, cortex a15) |
| 16:39.55 | gordan | Well, the Motorola Atrix combo is pretty well built. |
| 16:40.08 | gordan | But it's locked down by the boot loader. |
| 16:40.37 | gordan | That has a Cortex A9 combo with a pretty decent dock with mousepad/keyboard/screen. |
| 16:41.03 | gordan | If you relax your requirement to 10" they are available now. |
| 16:41.20 | gordan | AC100 is a _fantastic_ machine. |
| 16:41.56 | gordan | And if it's 512MB of RAM is not enough for you, then you can always go and fork out 3x the amount for a TF101. |
| 16:42.13 | gordan | That has a gig of RAM and an extra 1280x80 worth of pixel space. |
| 16:42.28 | gordan | But 1280x720 that you can upgrade the AC100 to is fine, I have one. |
| 16:42.44 | gordan | Hop over to #ac100 if you're interested. :) |
| 16:43.07 | gordan | And I'm sure you've seen links to my AC100 mods and hacks over on the mailing list. :) |
| 16:45.41 | gordan | With a few hacks and tweaks and a decent SD card to run the OS from, it is quite awesome. |
| 16:46.32 | gordan | You wouldn't believe how fast a 1400MHz Tegra2 is running off a decent SD card (note - there are VERY few decent SD cards around, random write performance generally sucks). |
| 16:54.38 | mnemoc | .oO |
| 16:58.34 | gordan | grins |
| 17:00.12 | gordan | For a kernel with OC-ing, 1280x720 support, AES offload support, and a few other fixes and updates, take a look at my tree on gitorious: https://gitorious.org/~gordan/ac100/gordans-marvin24s-kernel/commits/chromeos-ac100-2.6.38 |
| 17:00.32 | gordan | For the AC100, I mean. |
| 17:00.33 | A2Sheds | gordan: have you found a tegra device that has the PCIe bus at least on pcb traces? |
| 17:00.52 | gordan | Didn't TrimSlice have it wired up on the PCB? |
| 17:01.10 | A2Sheds | maybe to the GBethernet controller |
| 17:01.25 | gordan | No mini-PCIE slot? |
| 17:01.35 | gordan | The nvidia dev boards might have it, but I never had a chance to look at those, way too expensive for me. |
| 17:01.46 | A2Sheds | I was trying to find something like the Marvell client with a PCIe conn |
| 17:03.30 | A2Sheds | another hybrid laptop x86 and ARM |
| 17:03.41 | A2Sheds | http://www.linuxfordevices.com/c/a/News/Lenovo-ThinkPad-X1-Hybrid/ |
| 17:04.06 | gordan | And that's a Lenovo, too. |
| 17:04.23 | gordan | What's wrong with the Compulab SBC-A510? |
| 17:04.31 | gordan | Is that not up to your requirements? |
| 17:04.41 | A2Sheds | I'd still like to find an ARM board with a PCIe other than the Kirkwood clinet |
| 17:05.09 | gordan | The Compulab board isn't Kirkwood (ARMv5). It's Armada (ARMv7), so quite similar to Tegra. |
| 17:05.15 | A2Sheds | overpriced |
| 17:05.40 | gordan | Well, it's similar price to TrimSlice if you can get away with not buying the dev kit. |
| 17:06.03 | A2Sheds | I had high hopes for marvell |
| 17:06.08 | A2Sheds | oh well |
| 17:06.20 | gordan | If you're in UK, I'm happy to get a board for you at cost and post it to you so you don't have to buy a dev kit. |
| 17:06.39 | A2Sheds | <-- US |
| 17:06.44 | gordan | Hell, I'm happy to post it to you wherever you are, that's not the point. |
| 17:06.49 | A2Sheds | heh |
| 17:07.00 | gordan | But if you're in US you may get customs/import duty charges on top of it on your end. |
| 17:07.47 | A2Sheds | hardly anybody used a marvell in a tablet and among those no PCIe |
| 17:08.00 | gordan | If you decide you want it, poke an email in my direction (you should have it if you're on the mailing list) and we'll sort something out. |
| 17:08.16 | gordan | Armada is a relatively recent chip. |
| 17:08.28 | A2Sheds | I need a low cost board or keep on using x86 Atom |
| 17:08.39 | gordan | And kirkwoods are quite old and use a big process that runs hot for an ARM, and have no proper power management and clock scaling. |
| 17:08.43 | A2Sheds | yeah, lots of problems |
| 17:09.04 | gordan | Well, I'll have a couple of Atom N450 micro-ATX boards in a month or so. :) |
| 17:09.07 | A2Sheds | i tried to work with them, even friends in China that worked for them |
| 17:09.11 | gordan | Goong real cheap. :) |
| 17:09.16 | A2Sheds | silicon issues |
| 17:09.35 | gordan | It's the hangover from Intel development days. |
| 17:09.42 | A2Sheds | I'm going to design the A10 board for now |
| 17:10.01 | A2Sheds | i wish it had PCIe |
| 17:10.16 | gordan | Yeah, me too. |
| 17:10.36 | gordan | But in fairness - what would you hang off PCIe that you can't hang off USB or SDIO just as well? |
| 17:10.37 | A2Sheds | I'll probably have a version with a FPGA on the NAND bus |
| 17:10.58 | A2Sheds | real time low latency connections |
| 17:11.31 | A2Sheds | SDIO is faster than USB for interrupt latency but still too slow for my apps |
| 17:12.06 | gordan | is out of ideas |
| 17:12.35 | A2Sheds | a few more ARM stories on http://www.linuxfordevices.com/ this week |
| 17:12.59 | A2Sheds | wondermedia and GoogleTV switching to marvell |
| 17:13.33 | gordan | aways |
| 17:13.47 | A2Sheds | there was a dev that cracked the secure bootloader in the tegra |
| 18:17.22 | *** join/#arm-netbook gordan (~gordan@78-86-195-86.zone2.bethere.co.uk) |
| 20:59.46 | ManoftheSea | aes offload? |
| 21:04.46 | gordan | Aye. Tegra has an AES engine built into it. |
| 21:05.02 | gordan | If you're talking about what I said earlier. |
| 21:05.12 | gordan | But a lot of ARMs have AES offload built in. |
| 21:05.26 | gordan | Marvells do, as do Freescales, and Tegras. |
| 21:06.05 | gordan | The one on the Marvell Kirkwood is actually very good, it's faster than doing it in software, and it's free to boot (CPU is free to do other stuff at the same time). |
| 21:06.10 | gordan | It's asynchronous. |
| 21:06.25 | gordan | The Tegra one is the same but the performance isn't that great, doing it in software is fater. |
| 21:06.28 | gordan | faster even |
| 21:06.37 | gordan | But again - it's free. |
| 21:06.48 | gordan | The CPU is free to do other stuff while the AES engine is churning crypto. |
| 21:13.05 | A2Sheds | I guess I could have an FPGA with a DDR3 to PCIe interface on the A10 if I really wanted to |
| 21:21.55 | A2Sheds | I'll just be happy to get the specs before somebody manages to offend Allwinner |
| 23:05.02 | ManoftheSea | oh that's cool. |
| 23:05.37 | ManoftheSea | Crypto offload just makes too much sense. |
| 23:05.44 | ManoftheSea | Is that part of the Trustzone stuff? |
| 23:12.20 | mnemoc | A2Sheds: what have you found that could be considered (close to) offensive to Allwinner? |
| 23:31.19 | gordan | Not sure what Trustzone stuff is, but most ARM have a crypto co-processor of some description built in. Tegra only has AES, Kirkwood has AES and MD5, possibly also SHA1, can't remember off the top of my head. |
