| 19:40.32 | Alex[sp3dev]_ | probably the stride is wrong or something but my priority now is uboot. partially because I want to reuse fastboot code later on other devices (I actually want ubuntu on the galaxy s2, but that's another story) |
| 19:40.34 | mirage335 | Hmm, I would never have thought of that. |
| 19:41.41 | mirage335 | Alex[sp3dev]_: Ok, so the ioctl line in the code might need just a number change? |
| 19:41.56 | mirage335 | I could certainly that at random, if the number is small. |
| 19:43.07 | Alex[sp3dev]_ | mirage335: not the ioctl, but the framebuffer parameters like stride, probably. I tried adding some debug to the kernel driver but that didn't help much |
| 19:44.05 | Alex[sp3dev]_ | first of all, is fb really rgb and not yuv? maybe test via /dev/graphics/fb0? |
| 19:44.49 | mirage335 | TBH, I have no idea how to try that. I have not been successful in uploading valid frambuffer captures (from CM9) to /dev/graphics/fb0. |
| 19:45.17 | mirage335 | I did try all formats from the recovery firmware however, so if it was *just* the pixel format, I think I would have found that. |
| 19:45.38 | mirage335 | As in, I modified gralloc to use all the pixel formats the recovery firmware can use. |
| 19:46.18 | Alex[sp3dev]_ | I actually suppose the whole gralloc thingie may be wrong since pmem is deprecated. |
| 19:46.29 | Alex[sp3dev]_ | maybe we should disassemble the blob |
| 19:46.51 | Alex[sp3dev]_ | I'm just a bit busy this week with the exams and right now I'm exploring the modem traces |
| 19:47.03 | mirage335 | Unfortunately, you've lost me with that. I have no idea what tools would allow us to disassemble the blob on android, and I'm not familiar with android. |
| 19:47.27 | mirage335 | GNUtoo-desktop: Maybe you can make more out of that statement than me. |
| 19:47.38 | Alex[sp3dev]_ | mirage335: IDA Pro (at least the demo. or you could disassemble the disassembler and hack it) or just objdump -d |
| 19:48.36 | mirage335 | That's it? Sounds pretty difficult. |
| 19:49.32 | mirage335 | Sounds worse than trying to figure out what the recovery firmware is doing differently, in fact. |
| 19:50.29 | mirage335 | Alex[sp3dev]_: Also, to clarify, you're saying that pmem is used by gralloc, but not the recovery firmware at this point? |
| 19:51.36 | Alex[sp3dev]_ | mirage335: no, I've not checked. I just suspect that pmem is not used on omap and we should use ion memory manager or omap ioctls for memory allocation |
| 19:52.26 | GNUtoo-desktop | indeed pmem is not in the tuna kernel |
| 19:52.33 | GNUtoo-desktop | there is ion or something else tough |
| 19:52.39 | mirage335 | I see. |
| 19:53.09 | mirage335 | If it helps "grep -r -i pmem ." in "external/bootmenu/minu" returns nothing. |
| 19:56.39 | Alex[sp3dev]_ | hmm. why not just.. strace it.. |
| 19:57.14 | mirage335 | Because I have no idea how that would be done when the phone is just booting up the recovery firmware. |
| 19:59.47 | Alex[sp3dev]_ | ok, made some traces, let me see if they contain anything useful |
| 20:03.29 | Alex[sp3dev]_ | made a trace of surfaceflinger, but that's not extremely useful, only fbioget, no fbioput |
| 20:04.31 | GNUtoo-desktop | also the non-free gralloc uses non-free 3d graphics so that might be less usefull since the system is quite different |
| 20:05.04 | GNUtoo-desktop | Alex[sp3dev]_, btw you got GNU/Linux on galaxy nexus too? |
| 20:05.59 | Alex[sp3dev]_ | GNUtoo-desktop: not yet, it's a work phone and the aim is to make sure the boot path does not contain rootkits. actually, proprietary libs are OK since we can probably limit what they can access via MMU |
| 20:06.14 | GNUtoo-desktop | ok |
| 20:07.29 | Alex[sp3dev]_ | of course RIL, sound, GPS must be free. but when it comes to using GNU/Linux, I would agree to use PowerVR blobs. because I both like to practice opengl and because I'm not yet morally ready to rewriting an opengl driver |
| 20:07.53 | Alex[sp3dev]_ | ok, back to tracing |
| 20:10.44 | mirage335 | GNUtoo-desktop: Would that path be acceptable for Replicant? Because if we can limit what the blobs do, I don't see an absolute need to purge them either. |
| 20:11.23 | Alex[sp3dev]_ | mirage335: nope |
| 20:11.37 | mirage335 | ? |
| 20:12.39 | Alex[sp3dev]_ | mirage335: actually, it's not only about freedom (well, I would not trust free software running on proprietary hardware anyway) but about being able to reuse technology in other projects |
| 20:13.18 | mirage335 | Righto. I'm just saying I don't mind the PowerVR blobs too much as long as they can't do evil things. |
| 20:13.47 | mirage335 | And I am more suspicious of GPS/modem things myself. |
| 20:13.57 | mirage335 | Especially modem. |
| 20:15.17 | Alex[sp3dev]_ | mirage335: looks like on omap4, the BP does not have access to the AP RAM. still, we need to write the initialization code for fw loading. I have made some strace on my sgs2 and plan to analyze that |

| 20:18.27 | Alex[sp3dev]_ | mirage335: yes, I think 95% of code will be the same |

| 20:20.08 | mirage335 | Honestly though, I am not following this conversation all that well. For one thing, I don't know why we need to trace the propietary driver when the recovery firmware already works. |
| 20:21.00 | Alex[sp3dev]_ | mirage335: that's a bit easier. but I'm trying to strace recovery |

| 20:39.26 | mirage335 | GNUtoo-desktop: Ok. I know that's the final goal, but in the short term, I'm thinking we still have the modem blobs to take care of, as well as some applications, and that may deserve to get done sooner. |
| 20:40.26 | GNUtoo-desktop | then at the end you forget the long term goal..... |
| 20:41.17 | GNUtoo-desktop | you're free to do what you want personally |
