mithroOnly probably another 3 hours until my 3d print finishes14:06
_florent_it takes time...14:13
_florent_have you been able to test the VideomixerSoC?14:13
mithro_florent_: yes14:13
mithro_florent_: I've gotten as far as making some small changes to the firmware14:15
mithro_florent_: I've also had passthru from my laptop to a monitor working14:16
mithro_florent_: and used your to rip an image out of the framebuffer14:16
_florent_ok good!14:17
_florent_I'm looking at the jpeg encoder14:17
mithro_florent_: still trying to get my head around how everything operates - it is still a little bit magical at the moment :P14:17
mithro_florent_: I need to figure out how the whole memory system works14:24
_florent_the framebuffer generates the video from memory according the resolution you have selected14:28
_florent_dvisampler simply write incoming video to memory14:28
mithroYeah, 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 is14:29
mithro_florent_: does that mean we are triple buffering currently?14:30

mithro_florent_: cool - so where is the implementation of that? The dvisampler_isr?14:34
sb0mithro, urjtag is forcing users to set up that rc file. doesn't have anything to do with migen.14:35
sb0the proper option is to fix urjtag14:35
_florent_mithro: yes, buffers are managed in dvisampler_isr14:37
sb0which, unike the xilinx shitware, should be doable14:37
sb0(speaking of shitware, X is unable to render fonts correctly at this temperature)14:37
mithrosb0: I no nothing about urjtag except what I learn't in the past 24-48 hours14:37
sb0or the intel gpu driver, or whatever crap component is in there14:38
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 registers15:18
mithroDammit, I have to work tomorrow and I want to keep playing with this...16:12
