| mithro | hey ssk1328 | 04:29 |
| CarlFK | mithro: nope. I've pondered it... | 04:33 |
| ssk1328 | mithro: Hi | 04:43 |
| mithro | ssk1328: so, were are you at? | 04:43 |
| ssk1328 | mithro: Testing the reworked HDMI_OUT | 04:43 |
| ssk1328 | mithro: When I initiate two dmas, the output is defined from second dma | 04:45 |
| ssk1328 | mithro: Trying to debug this | 04:45 |
| mithro | ssk1328: Are you still working on getting the single output working? | 04:46 |
| ssk1328 | mithro: Yeah | 04:47 |
| mithro | ssk1328: Have you pushed the code somewhere to look at? | 04:48 |
| ssk1328 | mithro: Yeah | 04:48 |
| ssk1328 | mithro: I am gonna just push the latest stuff | 04:48 |

| ssk1328 | mithro: I have implemented the P4 diagram from mixed block diagram | 04:52 |
| mithro | ssk1328: Couple of things here (unrelated to your current issue) | 04:52 |
| mithro | ssk1328: For triple quoted strings you normally use the double quotes | 04:52 |
| mithro | ssk1328: You should also turn on spell checking in your editor | 04:52 |
| *** rohitksingh_wor1 has joined #timvideos | 04:52 | |
| mithro | ssk1328: and every ending punctuation (full stop, exclamation mark, comma, etc) should have whitespace (space, newline, etc) after it | 04:53 |
| *** rohitksingh_work has quit IRC | 04:53 | |
| mithro | The lack of whitespace after ending punctuation seems to be a very Indian thing - like saying "codes" rather than "code" | 04:54 |
| ssk1328 | mithro: Okay | 04:54 |
| ssk1328 | mithro: This is regarding documentation right? | 04:55 |
| mithro | ssk1328: yes | 04:55 |
| mithro | ssk1328: Your not using the float pixel stuff at the moment, right? | 04:55 |
| ssk1328 | mithro: I am actually | 04:55 |
| mithro | ssk1328: Did you get this system working with a dummy mixer block? | 04:55 |
| ssk1328 | mithro: Actually I did that for P2 diagram | 04:56 |
| ssk1328 | mithro: For the P4 I havent tested with dummy mixer | 04:57 |
| mithro | ssk1328: I'm confused - did you have the P2 diagram working? | 04:57 |
| ssk1328 | mithro: So P2 was working with dummy mixer block | 04:58 |
| mithro | ssk1328: Why did we switch to P4 if P2 was working? | 04:58 |
| ssk1328 | mithro: But that needed a lot of refactoring because of mixing modules worked at pixel clock and DMA was getting more than one pixel (actuallu packfactor) number of pixels per clock | 04:59 |
| ssk1328 | We had discussion here https://logs.timvideos.us/%23timvideos/%23timvideos.2016-08-09.log.html#t2016-08-09T14:36:39 | 05:00 |
| mithro | ssk1328: From that description, the dummy mixer in P2 never worked then? | 05:03 |
| ssk1328 | mithro: No, when tested the dummy mixer was just direct connections | 05:04 |
| mithro | ssk1328: okay - you should try getting P4 working with a dummy mixer first | 05:04 |
| ssk1328 | mithro: I have something working in P4 rightnow | 05:05 |
| ssk1328 | mithro: When I define two dmas and connect them to the mixer the output is defined by the base address of second dma | 05:06 |
| mithro | ssk1328: That doesn't sound like working? | 05:07 |
| ssk1328 | mithro: Okay so dummy testing first | 05:10 |
| mithro | ssk1328: Yes, the dummy mixer should just be something like a simple switch | 05:11 |
| mithro | ssk1328: To get this merged as well, we really need it split up | 05:11 |
| mithro | ssk1328: So, having a pull request where things are just refactored in a way needed to add a mixer is a good start | 05:11 |
| ssk1328 | mithro: Okay | 05:11 |
| ssk1328 | mithro: Without the floatarth modules I suppose? | 05:12 |
| mithro | ssk1328: Yes | 05:12 |
| ssk1328 | mithro: Okay, they are actually already pushed in this branch | 05:13 |
| mithro | ssk1328: You can create a new branch and copy accross the stuff you need | 05:13 |
| ssk1328 | mithro: Yes | 05:13 |
| mithro | ssk1328: We are really running out of time, so really need to see this working ASAP | 05:14 |
| ssk1328 | mithro: Yes, Need to complete this ASAP | 05:15 |
| mithro | ssk1328: So, lets get a minimal pull request which does the refactor as described in diagram P4 done | 05:16 |
| ssk1328 | mithro: Okay | 05:16 |
| mithro | ssk1328: Can we aim to have that ready (even if it doesn't quite work yet) in a couple of hours? | 05:17 |
| ssk1328 | mithro: I have a TA meeting in 3 hours from now, I aim to get it done before that | 05:18 |
| mithro | ssk1328: Okay | 05:20 |
| ssk1328 | mithro: I have the mixing also working in reworked HDMI_OUT | 06:38 |
| ssk1328 | mithro: But I guess we need the pull requests to be separate? | 06:38 |
| mithro | Hrm? | 06:41 |
| mithro | Yes, we should have two separate pull request so we can review them. | 06:41 |
