| mithro | Only probably another 3 hours until my 3d print finishes | 14:06 |
| mithro | https://www.youtube.com/watch?v=w2iOxXTgTFA&feature=youtu.be | 14:06 |
| _florent_ | it takes time... | 14:13 |
| _florent_ | have you been able to test the VideomixerSoC? | 14:13 |
| mithro | _florent_: yes | 14:13 |
| mithro | _florent_: I've gotten as far as making some small changes to the firmware | 14:15 |
| mithro | _florent_: I've also had passthru from my laptop to a monitor working | 14:16 |
| mithro | _florent_: and used your test_dump.py to rip an image out of the framebuffer | 14:16 |
| _florent_ | ok good! | 14:17 |
| _florent_ | I'm looking at the jpeg encoder | 14:17 |
| mithro | _florent_: still trying to get my head around how everything operates - it is still a little bit magical at the moment :P | 14:17 |
| _florent_ | ;) | 14:20 |
| mithro | _florent_: I need to figure out how the whole memory system works | 14:24 |
| _florent_ | the framebuffer generates the video from memory according the resolution you have selected | 14:28 |
| _florent_ | dvisampler simply write incoming video to memory | 14:28 |
| mithro | Yeah, I get the high level theory - it's the details that I don't quite understand yet :) | 14:29 |
| _florent_ | you have multiple memory allocated to avoid the framebuffer to read a slot that the dvi sampler is | 14:29 |
| _florent_ | writing | 14:30 |
| mithro | _florent_: does that mean we are triple buffering currently? | 14:30 |
| *** sb0 has joined #timvideos | 14:32 | |
| *** sb0__ has quit IRC | 14:32 | |
| _florent_ | yes | 14:32 |
| mithro | _florent_: cool - so where is the implementation of that? The dvisampler_isr? | 14:34 |
| sb0 | mithro, urjtag is forcing users to set up that rc file. doesn't have anything to do with migen. | 14:35 |
| sb0 | the proper option is to fix urjtag | 14:35 |
| _florent_ | mithro: yes, buffers are managed in dvisampler_isr | 14:37 |
| sb0 | which, unike the xilinx shitware, should be doable | 14:37 |
| sb0 | *unlike | 14:37 |
| sb0 | (speaking of shitware, X is unable to render fonts correctly at this temperature) | 14:37 |
| mithro | sb0: I no nothing about urjtag except what I learn't in the past 24-48 hours | 14:37 |
| mithro | s/no/know/ | 14:37 |
| sb0 | or the intel gpu driver, or whatever crap component is in there | 14:38 |
| mithro | _florent_: what provides dvisampler_dma_slot0_status_read() - is that an autogenerated function from the sampler? | 15:08 |
| _florent_ | yes: csr.h is autogenerated and provides access functions for all registers | 15:18 |
| mithro | Dammit, I have to work tomorrow and I want to keep playing with this... | 16:12 |
| _florent_ | :( | 16:15 |
