| mithro | shenki: what needs to be done to make that USB-UART driver not conflict with other USB-UART stuff on the system? | 08:00 |

| tpb | Title: Installing Exar Driver · timvideos/HDMI2USB Wiki · GitHub (at github.com) | 08:01 |
| shenki | mithro: we need to add support to the upstream acm driver for the exar part | 08:04 |
| mithro | shenki: I don't care that much about getting the driver upstream, just making it so I can have the acm driver running at the same time as the exar part - is that possible or more work then the upstreaming part? | 08:07 |
| shenki | mithro: it might be possible, if someone wants to do that | 08:11 |
| shenki | mithro: it would be preferable to spend time supporting it in the upstream driver | 08:11 |
| shenki | mithro: isntead of a temp hack | 08:11 |
| shenki | mithro: that doesn't mean getting the support upstream | 08:11 |
| shenki | mithro: just hacking the upstream driver so it works for our part | 08:12 |
| mithro | I'm no kernel expert - but we can't really "patch" an included module without having to rebuild stuff right? | 08:13 |
| mithro | shenki: do we actually know why you can't have both modules loaded at the same time at the moment? | 08:19 |
| mithro | shenki: is it just that the cdc_acm driver associates with the device first? | 08:23 |
| *** tija has joined #timvideos | 09:26 | |
| shenki | mithro: the exar driver is a copy of the cdc_acm driver with the variables renamed | 09:40 |
| shenki | mithro: an d some ocde added to support exar | 09:41 |
| mithro | shenki: sure - but I can physically load both the exar module and the cdc module at the same time, right? | 09:42 |
| tija | mithro: Migen has so less documentation :( | 10:54 |
| mithro | tija: that is not a real sentence. | 10:54 |
| tija | mithro: I was going through the examples in their repo and lot of the objects used have no documentation. Atleast I couldn't find them | 10:56 |
| mithro | tija: most of the newer stuff they have been much better at documenting | 10:56 |
| tija | mitho: like? | 10:57 |
| mithro | hrm, there is less stuff then I recall | 11:04 |
| mithro | ahh, I was looking at the migen rather then the misoc code | 11:05 |
| mithro | Lots of the stuff in https://github.com/m-labs/migen/tree/master/migen/fhdl has docstrings for example | 11:06 |
| tpb | Title: migen/migen/fhdl at master · m-labs/migen · GitHub (at github.com) | 11:06 |
| mithro | I do agree that they could use better documentation on things | 11:07 |
| mithro | Have you seen https://migen.readthedocs.org/ ? | 11:08 |
| tpb | Title: Migen manual Migen X documentation (at migen.readthedocs.org) | 11:08 |
| tija | mithro: yes. Lot of stuff are missing. Unable to follow the examples with the available document. | 11:11 |
| mithro | tija: like? | 11:12 |
| tija | mithro: https://github.com/m-labs/migen/blob/master/examples/basic/fsm.py | 11:13 |
| tpb | Title: migen/fsm.py at master · m-labs/migen · GitHub (at github.com) | 11:13 |
| tija | No documentation about FSM() | 11:14 |
| mithro | tija: you understand what FSM stands for? | 11:15 |
| tija | yes Finite State Machine | 11:15 |
| mithro | so FSM() creates a new Finite State Machine module inside the current module? | 11:17 |
| mithro | btw, have you run the module and look at the verilog it generates? | 11:19 |
| tija | yeah what are the function inside the FSM module is not known. | 11:19 |
| tija | yesh I have. | 11:19 |
| mithro | tija: what do you mean? | 11:19 |
| mithro | you mean NextValue and NextState functions? They are imported at the top line | 11:20 |
| tija | I mean self.be = myfsm.before_entering("FOO") what does this do? | 11:20 |
| mithro | tija: creates a signal which triggers before the finite state machine enters state FOO ? | 11:21 |
| tija | synchronosly or async? | 11:24 |
| tija | Anyway forget it. I will figure it out. But the statement "Migen has so less documentation" is real. | 11:26 |
| mithro | tija: I know what you meant, but that sentence is still not grammatically correct | 11:37 |
| mithro | tija: Adding documentation to the module would probably be a good first patch! | 11:38 |
| mithro | Looking at the generated verilog code - I wonder what the "_is_el" append to the signal name means? | 11:39 |
| mithro | tija: join #m-labs | 11:40 |
| shenki | mithro: no, you can't add them both. you cant have the same module loaded twice | 12:12 |
