| 07:43 | scattym | Hey, anyone around that can help me migrate back to lircd from eventlircd on the geexbox build? |
| 07:47 | jnettlet | sorry I have not played around with either on the new builds. |
| 07:54 | scattym | no probs. |
| 07:55 | scattym | the guides I have followed so far don't seem to show which lircd driver I should use to point at the internal ir port, only for adding an external IR receiver... |
| 08:30 | warped-rudi_ | scattym, the internal IR port is enabled by default on geexbox |
| 08:32 | warped-rudi_ | jnettlet, speed testing with only one CPU gave no difference: HB->150MB/s i4pro->100MB/s |
| 08:33 | jnettlet | is it possible that the cpu-scaling is working differently on one vs the other. |
| 08:33 | jnettlet | there are a lot of factors that could play into this. |
| 08:37 | warped-rudi_ | hmm, any ideas where to look ? I'm using Rabeeh's 3.0.35 kernel with some tweaks... |
| 08:38 | jnettlet | cat /proc/cpuin |
| 08:38 | jnettlet | cpuinfo |
| 08:39 | jnettlet | but you can use the sysfs interface to limit both to the same frequency for testing |
| 08:41 | scattym | warped-rudi, thanks. I am having trouble with implementing the apple remote and was hoping to move to lircd where I had a little more control over the IR params |
| 08:41 | scattym | had = have |
| 08:44 | warped-rudi | interesting, the BogoMIPS change between 790 and 1988 on the i4. let's look what it does on the HB |
| 08:46 | scattym | oh, looks like you're in the middle of something. I'll check back later. |
| 08:50 | warped-rudi | scattym, I think switching to lirc is kinda documented on the geexbox web site. However, I don't know if this will work for the internal IR. |
| 09:02 | warped-rudi | BogoMIPS on the HB bounce between the same values. but less frequently. |
| 09:07 | mk01 | 1990 is ok per cpu (on 1ghz) |
| 09:31 | scattym | yeah, that's where I got stuck. I had been over the documentation on the web site. seems more targeted at an external ir receiver. will keep plugging away. thx. |
| 09:37 | jnettlet | warped-rudi, you are using the latest SPL based u-boot right? |
| 09:38 | jnettlet | I am getting 276 MB/s cached reads on my i4p |
| 09:40 | warped-rudi | Yes, latest commit from https://github.com/rabeeh/u-boot-imx6/ |
| 09:41 | warped-rudi | BTW, the reason why I noticed that something might be wrong is that the flow of messages from systemd is visibly slower on the i4 than on the HB. |
| 09:43 | jnettlet | warped-rudi, try this u-boot and see if there is any difference. https://dl.dropboxusercontent.com/u/736509/u-boot/uboot_debug.tgz |
| 09:44 | jnettle | 09:44 * jnettlet is going to walk the dogs now |
| 09:51 | mk01 | warped-rudi: internal IR should work with LIRCD with the help of "ir_lirc_codec" keymap. |
| 15:27 | matoking | Hey, anyone have an idea why my upload speed starts at 600 KB/s and then goes down to around 100 KB/s? |
| 15:27 | matoking | I've tried SFTP, FTP using vsftpd and Samba and all work like that |
| 15:28 | matoking | I'm using an USB HDD and I got a write speed of about 20 MB/s |
| 15:28 | mk01 | upload to Cubox ? |
| 15:28 | matoking | Yes |
| 15:28 | mk01 | 20MB/s is tested how ? |
| 15:29 | matoking | dd if=/dev/zero of=testfile0 bs=8k count=10000; |
| 15:29 | matoking | It's ridiculous since I can download from the Internet at around 800 KB/s at best |
| 15:30 | matoking | It's either my Linux laptop is doing a shoddy job somehow or my router is a piece of junk |
| 15:30 | mk01 | it is Eth connected or Wlan ? |
| 15:30 | matoking | WLAN |
| 15:31 | mk01 | iwconfig wlan0 is showing what ? |
| 15:32 | matoking | @mk01 http://pastebin.com/fzucte1U |
| 15:32 | matoking | To be fair I've had hard times with the router |
| 15:33 | matoking | For example, refreshing the server list in TF2 would bring down the Internet connection for a few minutes |
| 15:33 | matoking | And now that I'm running a P2P application on the Cubox-i the connection has a higher latency even if it's all happening on the local network |
| 15:36 | matoking | Hmm |
| 15:36 | mk01 | with 802.11g (max 54MBps) you get ~2MB/s in real life. |
| 15:36 | matoking | Yeah, that's about the upload speed I get when I upload from my Linux laptop to my phone over FTP |
| 15:37 | matoking | Although it too drops a bit |
| 15:37 | matoking | But yeah, I did a bit of googling and most people seem to agree |
| 15:37 | matoking | This router *is* a piece of junk |
| 15:37 | mk01 | it all depends on other networks, noise etc |
| 15:37 | mk01 | change the router for N capable. |
| 15:38 | mk01 | you can investigate more by turning off powersave mode (you have on) and "iw scan |
| 15:38 | mk01 | "iw scan". you will see networks around you |
| 15:38 | mk01 | overlapping channels / etc |
| 15:38 | matoking | Oh |
| 15:39 | matoking | Power management |
| 15:39 | matoking | How can I turn it off? |
| 15:39 | mk01 | iwconfig wlan0 power off |
| 15:39 | matoking | Well that's a bit ambigious isn't it :P |
| 15:40 | matoking | Started at 1.2 MB/s and dropped down to around 80 KB/s :/ |
| 15:41 | matoking | I'll have to do some testing |
| 15:41 | mk01 | then check neighbour networks |
| 15:41 | mk01 | iwlist scanning |
| 15:41 | matoking | There is only one network around here |
| 15:41 | matoking | It doesn't pick up anything else |
| 15:41 | mk01 | or "iw wlan0 scan" |
| 15:42 | mk01 | try to set open network |
| 15:42 | mk01 | so no WEP/WPA/WPA2 |
| 15:42 | mk01 | (just for test) |
| 15:42 | matoking | It's already open |
| 15:42 | mk01 | ah |
| 15:42 | matoking | (I know that's a bad idea) |
| 15:42 | matoking | But I know to use SSL if I'm dealing with anything sensitiv |
| 15:42 | matoking | So no worries about that |
| 15:43 | mk01 | what channel is your net and the one you can see around ? |
| 15:43 | matoking | Channel 6 |
| 15:44 | matoking | There are no other Wi-Fi networks around here besides the one I'm using right now |
| 15:45 | mk01 | then it is straightforward. change router for Ncapable or connect Cubox with lan |
| 15:45 | matoking | Yeah |
| 15:46 | matoking | A FYI for other people who may be listening |
| 15:46 | matoking | Don't buy ZyXel routers |
| 15:47 | mk01 | Buy one with chipset running linux |
| 15:47 | matoking | For dd-wrt? |
| 15:48 | mk01 | dd-wrt / openwrt ... yes |
| 15:48 | matoking | Hmm |
| 15:48 | mk01 | sometimes its the FW what is crap. even with solid HW and price. |
| 15:50 | mk01 | (if you have $$ to waste buy AirPort Capsule or Extreme station ;) ). you will get 20-25MB/s. |
| 15:52 | matoking | I'd rather use something I can hack as I wish :) |
| 15:53 | _rmk_ | matoking: it could be that the sdhci driver is causing the slow down, or the linux mmc layer. I've been going through it in 3.14-rc2 during the last week fixing lots of stuff there. |
| 15:53 | _rmk_ | matoking: if the linux mmc layer hasn't been told that the host driver can signal sdio interrupts, then it'll poll for them instead |
| 15:54 | matoking | @_rmk_ I'm using an USB HDD, does that matter? |
| 15:54 | _rmk_ | matoking: also, if the sdhci driver does runtime PM, that can have an adverse impact too |
| 15:54 | _rmk_ | the wireless is connected to a sdhci interface |
| 15:54 | matoking | Oh |
| 15:54 | matoking | Hmm |
| 15:55 | matoking | I'm using the debian-jessie build |
| 15:55 | _rmk_ | I can't speak for the freescale 3.0.35 kernel since I work on mainline stuff |
| 15:55 | matoking | I suppose this fix will be as easy as installing a new kernel? |
| 15:55 | matoking | Provided it's fixed, that is :) |
| 15:55 | _rmk_ | and I've no idea what debian are doing with their kernel for imx6 |
| 15:55 | _rmk_ | I haven't pushed my changes anywhere yet because it's work in progress |
| 15:56 | _rmk_ | what I'm saying is I've already found quite a bit of yuck in the v3.14-rc2 version |
| 15:56 | matoking | 3.0.35-g0f2006c-dirty |
| 15:57 | matoking | Yeah, my kernel doesn't seem to be exactly up-to-date :P |
| 15:57 | _rmk_ | sounds like it may be derived from the freescale kernel |
| 15:57 | matoking | Ah |
| 15:57 | _rmk_ | freescale's official BSP is based off 3.0.35 |
| 15:58 | _rmk_ | to say whether any of this stuff is relevent, I'd need to dig into that tree |
| 15:59 | _rmk_ | I'm at 27 patches for it, two from someone else, and the more I look at the driver, the more patches I have. |
| 15:59 | matoking | Do you have a repository with those patches? |
| 16:00 | _rmk_ | well, I haven't yet even build tested about eight of these yet |
| 16:00 | matoking | Oh, and it seems the mainline Linux kernel already has some Cubox-i-related changes in it |
| 16:01 | _rmk_ | yes, that's me pushing it upstream, which provides basic support only atm |
| 16:01 | matoking | Nice :) |
| 16:02 | _rmk_ | I'll take a look at some point - but I'm going to be rather distracted at times because we've got quite a bit of storm damage from the last two months to deal with. |
| 16:06 | _rmk_ | at the moment, it's still pretty windy so not going down the bottom of the garden in case of being squished by any further falling tree branches |
| 16:37 | jnettlet | matoking, I found a bug with cpuidle that caused network latency problems. You should try disabling it and see if things look better. |
| 16:48 | matoking | @jnettlet How do I do that? |
| 16:49 | jnettlet | matoking, it will be under /sysfs/devices |
| 16:50 | jnettle | 16:50 * jnettlet now questions if the 3.0.xx kernels had the sysfs entry to disable cpuidle |
| 16:50 | jnettlet | do a find in /sysfs to see if you can find cpuidle. That kernel may be too old |
| 16:50 | matoking | You mean /sysfs in root? |
| 16:51 | matoking | Oh, right, sys |
| 16:51 | jnettlet | yeah, it is sysfs mounted to /sys |
| 16:52 | jnettlet | sorry doing too many things right now |
| 16:52 | mk01 | # CONFIG_CPU_IDLE is not set |
| 16:52 | mk01 | so there will be no /sys or debugfs entry |
| 16:53 | matoking | Nope, can't find cpuidle under /sys |
| 17:01 | matoking | Am I right in guessing that there are multiple kernel versions in use, since people on the forums are reporting better performance? |
| 17:02 | jnettle | 17:02 * jnettlet has no idea |
| 17:04 | matoking | Or they could be using the Ethernet port instead of Wi-Fi |
| 18:54 | warped-rudi | jnettlet: I tried your debug u-boot, but no change. Behaviour exactly the same. |
| 19:04 | jnettlet | warped-rudi, if you are bored you could install and run lmbench on both machines. I will run them on mine also so we can compare |
| 19:17 | warped-rudi | I'm running geexbox on the machine. So I have to look how to cross-compile that tool... |
