I'm looking for details for the PN544 and/or PN65N NFC chips inside the Nexus series, as in technical documentation. Can anyone help me? Thanks!

HTC just dropped BlueZ sources on their developer page. Maybe this will help?

HTC Desire 720p When the source drops for the HTC Desire froyo update (... realistically the source is probably months away ...) we can see how they do it (with access to all Qualcomm and Samsung engineering docs and resources) and copy that.

Hi charnsingh, I just read this, http://www.anandtech.com/show/3794/the-iphone-4-review/8, and noticed this: "What's interesting is that the iPhone 4 appears to crop the sensor down for video recording, taking the center most 1280x720 pixels instead of scaling down the entire image size. The...

No. It's not USB, but is instead raw analog video on the same connector. The N1 does not have the necessary internal wiring for this to work.

Gutted. What I would be interested in is how to set up the sensor to output pure, raw Bayer-mosaiced image data with no signal processing done on it. I think we would also like to read the chapter about the VFE (video front end) in the QSD8250 manual. I would also be interested in any...

Would you mind sharing the datasheet? I know a lot of people including myself would be very interested in camera-hacking but don't want to go through the hassle of reverse engineering.

Sven, have you tried to make OTG mode (dynamic host/peripheral switching) work properly yet? There seems to be all the required patches upstream for it to work, e.g. https://www.codeaurora.org/gitweb/quic/chrome/?p=kernel.git;a=commit;h=731e94b44438268741e77db8db3fc91ee9d9acb2 Also, have you...

Regarding RGB565, a Google-employed Android project kernel hacker who on occasion visits this forum (swetland) confimed that the physical wiring to the AMOLED panel is only RGB565/16-bits. The one-bit change you mention is in the panel configuration data and probably tells the panel to expect...

I can see nothing in the driver suggesting FM support... I'd imagine that the FM support would fall into either a separate driver or perhaps the Bluetooth driver for that chip (as it operates through that part of the chip and shares audio inputs/outputs with the Bluetooth). Aaaannnnd I can't see...

802.11n works with the stock ROM, but it's only at 2.4 GHz (the phone doesn't appear to include the necessary antenna and RF components to work with the 5 GHz band). It's also only single-stream N, so you won't get link speeds higher than 65 Mbit. Maybe they didn't advertise it because it's only...

Can you please update your github repo when you get a chance? Thanks Raven.

Not necessarily, but in theory it lets the system always use the absolute minimum amount of energy to guarantee stability.

What?? Really? The Chromium kernel has ugly hacked voltage regulator drivers that don't use the kernel regulator framework; our kernel uses the proper approach. Don't break that!

https://www.codeaurora.org/gitweb/quic/la/?p=kernel/msm.git;a=commit;h=8a68421a300878d729991c1db609a541910d2c70 Here is another patch (more up to date -> perhaps easier to merge).

Is this what you're after: https://www.codeaurora.org/gitweb/quic/chrome/?p=kernel.git;a=blob;f=drivers/mfd/tps65023.c;h=1bf98b4a20bb731339580033c825011199a7bf1e;hb=refs/heads/msm-2.6.31.12 (line 37) I'm not sure what you mean by "I believe it is safe to take it out"... if you take out the...

I guess you already know this, but the TPS65023 is a voltage regulator IC that contains several voltage regulators (DC-DC converters). DC-DC1 provides voltage for the Scorpion applications processor core. I would imagine this function: static int tps65023_dcdc_set_voltage(struct regulator_dev...

My name is hugonz, not honz :-)

True, but the comment doesn't agree with the code itself: /* axi 128 screen on, 61mhz screen off */ <snip> static void axi_late_resume(struct early_suspend *handler) { axi_rate = 128000000; sleep_axi_rate = 120000000; // <- 120 MHz... clk_set_rate(axi_clk, axi_rate); } I wonder if we...

Ivan, I saw this: https://www.codeaurora.org/gitweb/quic/chrome/?p=kernel.git;a=commit;h=79dc19caf2ccc7df38106e2bbd1445437970a8a0 Disable AVS and update default ACPU voltage to 1300mV for ST1 AVS is disabled for stability reasons since it incorrectly steps down the voltage at 1GHz leading to...

So I've been traipsing through some of the other Qualcomm repositories searching for tidbits that might be of use for N1 kernels. As far as I can tell, none of these changes have been merged in to the aosp or cyanogen kernels, although unfortunately the underlying kernels have diverged and these...

It's still only Class 2! I'd probably prefer a Class 6-10 16 GB.

Actually, my understanding (I'm a professional electrical & electronics engineer) is that AVS changes voltage primarily in response to temperature, which changes performance characteristics of the silicon. Process variations (sample differences between two copies of the same CPU, e.g. from...

Hi all, So, I'm trying to establish whether it is possible for the community to add DivX support. I see commits like these: https://www.codeaurora.org/gitweb/quic/la/?p=platform/vendor/qcom-opensource/omx/mm-video.git;a=commit;h=69023cf85787ff454ce0549f532f9aecfad2ae29...

I don't want to get into the debate about whether you're behaving like a sane, well adjusted adult in this thread, but I would like to remind you that under the terms of the General Public License, version 2 (underwhich the copyright holders of the Linux kernel have licensed the kernel, and by...

So the Desire is shipping now, which means that HTC is legally obligated to release the GPL parts of the source code, namely the kernel. Does anyone know how long it normally takes HTC to get their kernel source online after a product release? Older products' source is at...

That's not exactly what I said; it would be easier with hardware documentation, but the table looks pretty self-explanatory to me (for each brightness level there is a 7-point gamma curve for each of the R, G, and B components). I haven't yet rooted my phone but it's something I'll definitely...

My understanding is it could be trivially fixed with a firmware update. I think the reason none of the modded/third-party kernels have done is is because it would require special colour measurement equipment, and (given that the technical docs for the AMOLED are not publically available) quite a...

I get this (or a similar) problem too. I'm not yet sure if it's a hardware or software problem, and am therefore avoiding rooting my phone until I'm sure. I have noticed that this happens more often, or at least seems to be more likely, when the phone is cold... I've not had it happen during...

It seems likely the JIT will finally ship http://code.google.com/events/io/2010/sessions/jit-compiler-androids-dalvik-vm.html Early/leaked/(faked?) benchmarks show significant performance boosts across the board.

Have you tried the audio-boost software hack? I'd imagine that is infact the only difference.

Ivan, I just noticed this in the AVS kernel documentation: "AVS assumes it is the only process changing the supply voltage. Other coprocessors must not change the Scorpion voltage. The bootloader must not change the Scorpion Voltage when warm booting from power collapse." It could...

Actually, at some stage, HTC have to publish the Desire kernel source (on developer.htc.com). I would imagine that the FM radio needs some kind of kernel support and I hope it won't be a binary-blob kernel module. It should actually be a really simple driver, so I can't imagine why they wouldn't...

Can you/someone confirm it is 3.3V? Not 1.8V?

Also, the upstream (AOSP) MSM kernel tree is still at .32... I would guess they may be stabilizing for a release as they've merged the -stable patchseries too (2.6.32.9 etc).

Funny that: a processor rated for 1 GHz (in a world where if they could get away with selling it as a 1.1 GHz processor they certainly would have) isn't actually capable of 1.1 GHz without compromising stability and/or lifetime. Who'd have thought :p Cheers for porting it to your kernel though...

Yeah I know, but this is their Chromium/ChromeOS kernel, not their Android kernel. Might have gone unnoticed (I for one, had not thought to look there -- I'd have thought the only Chrome-specific kernel changes would've been the X11 driver -- why should platform-power-management changes not be...

So I was just looking around the Qualcomm open source (CodeAurora) repositories and noticed that lots of interesting things are going on over there for the qsd8x50 that aren't yet in our N1 kernels. One of the most potentially useful things to us, is adaptive undervolting, that always chooses...

Not necessarily: the two added bits could be the least significant bits in which case it would still work, with the panel controller silicon reading zeros (assuming those lines were tied low on the PCB). You wouldn't even notice (colors would have shifted ever so slightly), but the color depth...

FYI, this isn't a 1GHz Snapdragon (Qualcomm) - it's a new 1GHz Samsung processor, basically a speed bump to the current Samsung application processors (like those used in iPhones).

Well, having dug further into the kernel source (specifically, drivers/video/msm/mdp_lcdc.c and arch/arm/mach-msm/board-mahimahi-panel.c) I can confirm that on the UTMS/GSM revisions, the hardware interface to the OLED panel is definitely RGB565 (and on the upcoming CDMA/Verizon version it...

These commits: 7541c803fdb9f49f84bbc19217dce7cdc5c1748d 086b30d3c51f2cb9599fcb923918c58dfd099e19 929ee91e83a3ef380b9c0ab573185d28923c846d in the CodeAurora kernel/msm.git tree (sorry, can't post the direct link because the forum won't let me) aosp/android-msm-2.6.32 head appears to add RGB666...
