| mithro | Yeah - I backed one to pull apart and see if we can load our own firmware onto it | 09:06 |
| mithro | _florent_: ping? | 09:11 |

| mithro | _florent_: ping? | 12:09 |
| _florent_ | hi mithro | 12:36 |
| mithro | _florent_: got some time to chat? | 12:36 |
| _florent_ | just a little | 12:36 |
| mithro | _florent_: did you end up taking a look at https://docs.google.com/document/d/1L8lz7u2uj6MrzSQv4b1Vk6Rmic26okyRklOju5IWLYA/edit#heading=h.6bl97udbymv4 ? | 12:36 |
| tpb | Title: MiSoC HDMI refactoring - Google Docs (at docs.google.com) | 12:37 |
| _florent_ | yes, we can indeed try to share things and have various phy | 12:38 |
| _florent_ | this can eventulally be done when trying to add GTP support on spartan6 | 12:39 |
| mithro | _florent_: I think it'll become more important when we start getting things like CEC, the data islands, etc | 12:39 |
| _florent_ | yes or when we will support at least 2 phys | 12:41 |
| mithro | I think there are ~4 "phys" we care about in the short term | 12:43 |
| mithro | in order of priority - (1) Spartan 6 SERDES, (2) Spartan 6 GTP, (3) Series 7 SERDES and (4) Series 7 GTP | 12:43 |
| _florent_ | yes | 12:46 |
| _florent_ | I also have migen code for ADV7511 | 12:46 |
| mithro | _florent_: released? | 12:46 |
| _florent_ | I removed it from my github account but I can share it | 12:47 |
| mithro | _florent_: with something like ADV7511 there isn't much to share with the rest right - the chip does pretty much everything, we just need a DMA engine to get the data into memory and some type of library to poke the settings in and out of the chip? | 12:48 |
| _florent_ | yes the only interesting things are YCbCr 4:2:2 conversion (which is required with the way the Xilinx boards use that chip) and I2C configuration | 12:49 |
| _florent_ | but anyway that's better without such external chip | 12:50 |
| mithro | _florent_: Any idea how portable the current stuff between Series 7 and Series 6 SERDES is? | 12:52 |
| mithro | I assume we probably want to take advantage of some of the better features in the S7 stuff? | 12:53 |
| mithro | _florent_: did the idea that it would take ~2 weeks worth of your time to get the GTP working for HDMI sound reasonable? | 12:57 |
| mithro | _florent_: I know they can be super tricky to get working correctly | 12:57 |
| _florent_ | for Spartan6, we only need to get the GTP configured correctly | 12:58 |
| _florent_ | we can reuse Series 7 code that is used on top of GTP | 12:58 |
| _florent_ | I think we can find HDMI example designs for spartan 6 that can help us | 13:02 |
| _florent_ | so that should not take too long | 13:02 |
| mithro | _florent_: There is XAPP1077 that talks about using the GTP for HDMI RX - but that mainly concentrates on the physical problems | 13:05 |
| mithro | _florent_: do you have time to work on the GTP stuff? | 13:11 |
| mithro | _florent_: From my point of view, getting the GTP stuff working is higher priority then getting the Atlys quarter rate stuff working | 13:14 |
| _florent_ | ack, I won't have too much time before end of next week I think | 13:17 |
| mithro | _florent_: for information on doing the HDMI via the DisplayPort adapter take a look at http://hackipedia.org/Hardware/video/connectors/DisplayPort/VESA%20DisplayPort%20Interoperability%20Guideline%20v1.1.pdf | 13:18 |
| _florent_ | sorry I have a meeting, I'll be back later | 13:20 |
| mithro | _florent_: no worries, I'll probably be asleep when you get back | 13:22 |
| mithro | _florent_: need to be careful to not get an "active" adapter | 13:22 |
