| 03:30.25 | s_j_newbury | I've recently been trying to add SRAM support to the pxafb driver only to come across http://wiki.xda-developers.com/index.php?pagename=UniversalProgress |
| 03:32.51 | s_j_newbury | It seems it's already been done, but I can't find any trace of a patch or a CVS repository containing the updates. :( |
| 03:35.32 | s_j_newbury | If anybodys interested I have a a complete port of Gentoo Linux to EABI/iWMMXt (gcc-4.1.1/glibc-2.5) that I need to share! ;) |
| 05:26.10 | lamikr | s_j_newbury: Hi Do you know is the eabi compiler & glibc yet ported to armv4/armv4t? |
| 05:27.24 | s_j_newbury | <PROTECTED> |
| 05:29.16 | s_j_newbury | I'll try building a Gentoo toolchain targeted at armv4 or v4t if you want |

| 12:11.22 | rob_w | i dont know this name now .. |
| 12:11.24 | s_j_newbury | I did look there previously but I assumed it must have been elsewhere since I couldn't see anything relevent |
| 12:13.45 | s_j_newbury | It was announced here: http://forum.xda-developers.com/showthread.php?t=251584 |
| 12:17.10 | s_j_newbury | But milanvot stated that there was a cosmetic issue that he wanted to fix before committing it to CVS. That was a few months ago now. GIven the status of the Universal port given here: http://wiki.xda-developers.com/index.php?pagename=UniversalProgress I would assume that the patch got into the most recent test kernel (2.6.16) if not into the CVS repo. |
| 12:17.57 | rob_w | be patience for cr2 to show up alive .. he will be your guru for universal |
| 12:18.10 | s_j_newbury | So maybe (hopefully!) it's been shared with cr2... :-) |

| 13:17.33 | s_j_newbury | I've been trying to do the same thing myself and despite writing a lot of code I've failed to get it to work. |

| 13:22.22 | s_j_newbury | rob_w said cr2 was the mostly likely person to ask |

| 13:52.13 | goxboxlive | ok i c |
| 13:53.08 | s_j_newbury | The patch was from somebody called "milanvot"..? |
| 13:59.20 | goxboxlive | ok, i c. It's a long time since he where active in the development. I guess you have to wait for cr2. I havent seen him for a couple of days (active) here, but he is here allmost every evening. |
| 13:59.56 | goxboxlive | Another thing you might try, is to post on the xda-developers forum. He will answer you there also i guess. |
| 14:00.04 | s_j_newbury | ok thanks. |
| 14:01.56 | s_j_newbury | I'll have another poke at my own code maybe I'll get it working ... I'm not optimistic, I think I've misunderstood something somewhere... |
| 14:03.36 | goxboxlive | what are you trying to build? |
| 14:05.14 | s_j_newbury | I'm trying to split the framebuffer memory bwtween the SRAM and SDRAM. I've set up all the DMA descriptors as decribed in the PXA27x reference manual, but I can't get the memory mapping to work. |
| 14:05.58 | s_j_newbury | I've been stareing at the code for a couple of months now on and off. |
| 14:10.57 | s_j_newbury | It is something definitely worth getting working. As it stands the performance "feels" worse then my old RiscPC back in the mid nineties with an original StrongARM! Most of the bus is taken up with updating the display. |
| 14:43.22 | rob_w | s_j_newbury, how is it going ? |
| 14:43.44 | rob_w | my boss just decided to start engineering pxa270 based based boards .. |
| 14:44.12 | s_j_newbury | buioding custom boards? |
| 14:44.20 | s_j_newbury | building* |
| 14:44.28 | s_j_newbury | excuse my typing |
| 14:44.57 | rob_w | after looking at its specs , i cant get that all htc px270 pdas come with an army of companion chipse although px270 brings all those functions |
| 14:45.14 | s_j_newbury | it is a little odd |
| 14:45.26 | rob_w | s_j_newbury, we will purchase cpu module boards where we can design custom base boards around .. |
| 14:45.53 | rob_w | s_j_newbury, why do you need to do that split ? |
| 14:49.05 | s_j_newbury | The PXA LCD controller can either use the internal SRAM or the main system RAM or a combination of each. The bus is quite limited in bandwidth and the LCD controller lacks any accelleration so every refresh the whole framebuffer gets transferred |
| 14:49.58 | *** join/#htc-linux anYc (i=mario@hadince17.hadiko.uni-karlsruhe.de) |
| 14:50.00 | rob_w | so you split it in half to stretch the traffic ? |
| 14:50.55 | s_j_newbury | Anything in the SRAM is CPU local and so essentially free.Ideally all the graphics buffers would be best off there |
| 14:51.16 | rob_w | free in therms of best speed ? |
| 14:52.05 | s_j_newbury | free as in not taking up any bus bandwidth from anything else - such as disk IO, net IO, general memory accessess etc |
| 14:52.18 | rob_w | i am with ya |

| 14:53.56 | s_j_newbury | What the PXA27x can do though is chain the DMA tranfers so that when it reaches the end of the SRAM it can then complete the transfer in DRAM. Then only the remaining memory gets transferred |
| 14:54.26 | s_j_newbury | QVGA can fit entirely in the SRAM |
| 14:54.33 | s_j_newbury | and so go very fast |
| 14:56.33 | s_j_newbury | I've found it very easy to starve the LCD controller by using DMA bursts or disk accesses |
| 14:58.01 | s_j_newbury | The compainion graphics chip completely alliviates all the problems though |
| 14:58.30 | s_j_newbury | or you could just stick with QVGA! :P |
| 15:02.33 | s_j_newbury | What I tried to do in my attempt is make a virtual re-mapping of the framebuffer covering both the SRAM and DRAM and point the descriptors at each region. I wonder if I was over complicating things... |
| 15:08.48 | rob_w | hmm |
| 15:09.52 | rob_w | so why would you like to mapp on purpose even before the SRAM is full ?? |
| 15:11.05 | s_j_newbury | My Zaurus has VGA it needs a framebuffer larger than the 256KB of SRAM |
| 15:11.44 | rob_w | but the chain mode you mentioned will do this automatilcy if data is bigger then qvga |
| 15:13.09 | s_j_newbury | Well it will follow a descriptor chain. That needs setting up with the physical addressess of the buffers |
| 15:13.27 | rob_w | ah nad thats what you want to do |
| 15:14.02 | s_j_newbury | but as I understand it from the user side you just write/read from a linear mapping... |
| 15:14.28 | rob_w | i am really keen to get more of this stuff ,, and if am lucky , short term future will bring me that |
| 15:15.02 | s_j_newbury | yeah, I just threw myself in though... |
| 15:15.06 | rob_w | s_j_newbury, yeah it sounds to me like an "integrated feature" |
| 15:17.10 | s_j_newbury | rob_w: sorry can't private message since I'm not registered apparently |
| 15:17.27 | rob_w | np |
| 15:17.52 | rob_w | i hope i get my evaluation kit soon |
| 15:18.33 | s_j_newbury | should be a nice toy.. |
