| blueCmd_ | stekern: that's fine, if you send me a pull request I'll merge it | 01:18 |

| blueCmd_ | http://storage.googleapis.com/bluecmd/zos.png you have to give IBM that they like colors at least | 01:18 |

| stekern | blueCmd_: I found a fencing error too | 07:48 |
| stekern | but apart from that, I can read and write all addresses | 07:48 |
| stekern | linux doesn't boot at all with 1G enabled, and behaves irratically with 512MB enabled | 08:14 |
| stekern | hmm, I get a feeling that the iomaps and the RAM mapping into kernel space somehow step on each other when ram > 256 | 12:30 |
| poke53282 | Below 2GB this should not happen. Did you implement an A31 gate accidentally? | 19:00 |
| tariq786 | hi | 19:05 |
| tariq786 | i am looking for Stefan Kristiansson or anyone who can answer a few questions about HDMI support in Openrisc | 19:06 |
| stekern | that would be me | 19:08 |
| tariq786 | hi stekern | 19:09 |
| tariq786 | i am not able to find the place where you have added HDMI support | 19:10 |
| tariq786 | can you help me with that? | 19:10 |
| tariq786 | i am talking about verilog code | 19:10 |
| stekern | tariq786: the only thing related to hdmi is hacking up a xilinx whitepaper to connect it to this core http://opencores.org/project,vga_lcd | 19:15 |
| stekern | poke53282: A31 gate? | 19:16 |
| tariq786 | stekern: http://www.chokladfabriken.org/news/1 says | 19:19 |
| tariq786 | stekern: Support for frame buffer output on the Atlys boards HDMI output have been added. | 19:19 |
| tariq786 | It was achieved by using the OpenCores VGA/LCD 2.0 core and hooking it up to a modified version of Xilinx xapp495 (http://www.xilinx.com/support/documentation/application_notes/xapp495_S6TMDS_Video_Interface.pdf) | 19:19 |
| tariq786 | stekern: i am not able to find where you have connected Xilinx Xapp495 to VGA | 19:20 |
| stekern | ok, that's three years ago, but the code is here nowdays: https://github.com/openrisc/orpsoc-cores/tree/master/systems/atlys | 19:21 |
| stekern | I should rip out that hack, but my atlys board is broken | 19:21 |
| tariq786 | stekern: thanks. That looks useful. Let me check that out and get back to you in case of more questions | 19:24 |
| stekern | sure, no problem | 19:24 |
| poke53282 | stekern: Just a small connection to this one: http://en.wikipedia.org/wiki/A20_line | 19:38 |
| poke53282 | Where you could control the 20th bit of the address line via the keyboard controller. | 19:38 |
| stekern | ah, right | 19:51 |
| stekern | but I was probably wrong about the 256MB | 19:55 |
| stekern | up to 0x3fffc000 bytes of ram works, then it start to step on the fixed mappings | 19:55 |
