| 20:10.19 | detule | jonpry, reverting that last smd patch (restoring to your original) seems to make a difference for a few gsm users...want to see if that normalizes things for you, here's the patch for easy application http://pastebin.com/jNeYQJzq |
| 20:10.47 | detule | compiled http://dl.dropbox.com/u/38520332/3.2.11jonprys_tty_patch.tar.gz |
| 20:12.47 | jonpry | 3.2.11? |
| 20:13.07 | detule | that's what's in the autobuild |
| 20:13.11 | jonpry | wow |
| 20:13.20 | jonpry | last night i got an sod |

| 20:21.35 | jonpry | i'm not sure the results of this test are going to be helpful |
| 20:25.42 | jonpry | well it sort of works |
| 20:25.57 | jonpry | but time from call to ring has increased from 12 seconds to just over 30 |
| 20:26.49 | detule | er how would that be related? |
| 20:27.13 | detule | you mean you can see the CRINGs in the radio log but device doesn't ring, or no CRINGs at all? |
| 20:28.15 | jonpry | i'm not sure |
| 20:28.28 | jonpry | maybe i spoke too soon |
| 20:29.16 | jonpry | anyways this could all be 2 sides of the same coin. like my patch slows down smd traffic. and hyc's speeds it up |
| 20:29.51 | detule | right |
| 20:30.44 | jonpry | i don't see anything wrong with this reverted patch |
| 20:31.35 | detule | i think all of smd_tty/smd needs an overhaul from the new msm trees |
| 20:31.52 | detule | (though i looked and they still do memcpy) |
| 20:31.56 | jonpry | nah our stuff is better |
| 20:32.15 | jonpry | they couldn't get smd to work with ppp and had to invent rmnet |
| 20:34.03 | jonpry | i fully support not using high speed hacks on the ril or gps channels |
| 20:34.29 | detule | high speed hacks? |
| 20:34.42 | detule | oh |
| 20:34.43 | detule | got it |
| 20:34.55 | detule | so in that worker function differentiate based on tty->index or whatever |
| 20:35.04 | detule | we're not reading the gps channel anyways |
| 20:35.05 | jonpry | yeah that should work |
| 20:35.16 | jonpry | we don't do smd27? |
| 20:35.42 | detule | i mean it's in there, but we get all our gps info via rpc |
| 20:35.49 | jonpry | ic |
| 20:36.20 | detule | you should check out the xtra stuff |
| 20:37.42 | jonpry | working good now? |
| 20:38.19 | detule | yeah it's fine, i need to hunt down someone with amss5225 to try it out before i can send it to the ML |
| 20:39.09 | jonpry | such diligence |
| 20:40.01 | detule | rpc is black box to me, i figure i shouldn't make assumptions with that |
| 20:43.42 | detule | btw hyc reverted his own patch in the .27 tree in August so there may have been other problems with it |
| 20:43.42 | jonpry | if i could only find my patch |
| 20:43.52 | detule | which one? |
| 20:44.05 | jonpry | smd_tty ldisc stuff |
| 20:45.25 | detule | af8d799d52c8525189f6ae8efa4bce67a1b05218 in .39 branch |
| 20:46.39 | jonpry | thanks |
| 20:48.58 | jonpry | how do i view smd_tty.c from before that commit? |
| 20:50.44 | detule | git checkout af8d799d52c8525189f6ae8efa4bce67a1b05218^ arch/arm/mach-msm/smd_tty.c |
| 20:50.46 | detule | maybe |
| 20:50.57 | jonpry | git show af8d799d52c8525189f6ae8efa4bce67a1b05218~1:arch/arm/mach-msm/smd_tty.c |
| 20:51.58 | detule | fancy |
| 21:04.20 | jonpry | it compiled whatever it is |
| 21:08.12 | jonpry | might have the hotness |
| 21:08.53 | jonpry | http://pastebin.com/DdsWhsCw |
| 21:14.03 | detule | nice i think those queue delayed work are fine switch to queue work since it seems to me we are putting delay of zero |
| 21:14.24 | jonpry | except when we detect slab trouble |
| 21:14.45 | jonpry | which is now a possibility since we are back to using tty_flip_buffer |
| 21:15.13 | detule | oh i see |
| 21:16.56 | detule | i guess this should work unless that speed-up patch was breaking the data channell as well |
| 21:17.12 | detule | but your device is the prime test subject it seems so you would know |
| 21:17.36 | detule | (btw make sure you don't have those slow_sim whatnots in startup just so we're not getting any false positives) |
| 21:17.55 | jonpry | it must be able to recover or something. because people have always gotten faster data with hyc patch |
| 21:18.41 | detule | need to ask him why he reverted it in the .27 tree |
| 21:19.54 | jonpry | it appears theoretically solid |
| 21:20.55 | jonpry | its impressive that we are able to download at such high speed that removing a memcpy of the packets increases performance |
| 21:22.25 | detule | punch out time, later |
