[linux-sunxi] Re: i2s audio codec support for sun7i
Yes, I have i2s running on an A10 mars board. I just enabled the sunxi i2s in the kernel config, built the kernel and it worked. But the mars board has LED's on the I2S pins, so they are almost impossible to use as I2s. I hooked wires up to it for a test and it worked. It showed up in alsa, using aplay. I will have to look for my kernel, as I don't think I saved it, I am now trying to get I2S to work on an A20 olimex board, because it have the I2S brought out to a header. I have a kernel built and loaded, but the I2S does not show up in aplay, so I am trying to track down what I am missing. If I find my kernel log from the mares board, I will let you know. I do have the kernel .config if you want that. Dennis On Monday, April 7, 2014 10:48:48 PM UTC-6, Puneet B wrote: Hi Dennis, How you done i2s porting on A10?

[linux-sunxi] sunxi_mem driver ported to sunxi-3.4
Hi, some days ago, nove linked at the IRC channel a new armel release of libcedarv (http://dl.cubieboard.org/software/common/linux-codec-release-V1.2.rar) for Android and Sunxi kernels, along with some example code and doc. He also found an armhf version (http://dl.cubieboard.org/software/common/linux_codec_gnueabihf_20140327.tar.gz) for Android (it requires the ION memory allocator). Today I emailed Huang Benn from Cubietech asking for the sunxi-armhf version of libcedarv. He kindly sent me it (http://dl.cubieboard.org/software/common/A20-sunxi.rar), clarifying that it requires the 'sunxi-mem' driver from an Allwinner engineer. I found sunxi_mem here https://github.com/cubieboard2/linux-sunxi/tree/sunxi-3.3-cb2/drivers/char/sunxi_mem. It seems to be GPLv2+ code. I've ported it almost directly here https://github.com/juanfont/linux-sunxi/commit/e8937b50bc749cf1069b6881e0189831381d342b. I've tested it with the encoding examples from the linux-codec-release-V1.2 package and, although there are some color issues, the encoder appears to work. Is this code acceptable in the sunxi-3.4 branch? Should I proceed with a pull request? Greetings, Juan -- You received this message because you are subscribed to the Google Groups linux-sunxi group.

Re: [linux-sunxi] Re: i2s audio codec support for sun7i
An easy way to get I2S hardware is via a TI eval board. For example TAS5760 is $99 http://www.ti.com/tool/tas5760xxevm Look around on the site the eval boards range from 1W to 300W.

[linux-sunxi] u-boot-sunxi merged with upstream v2014.04-rc3
Hi All, I've just merged v2014.04-rc3 into the u-boot-sunxi branch. I've added a few patches on top to get everything working again. While merging v2014.04-rc3 into our sunxi u-boot branch, I hit a problem where mmc would no longer work in the SPL. The problem is that the new mmc_create call forces use of HEAP memory, while in the SPL there may be no HEAP. For now I've created a small 2048 bytes HEAP in our SPL, I've send a mail to the u-boot list to discuss this.

[linux-sunxi] [PATCH 3.4] arm:sunxi:defconfig: Better ROOT_NFS support for sun4i and sun7i
This patch ensures that default configs allow multiple sun4i and sun7i devices boot and work nicely with the same NFS root. Tested with Cubietruck, Cubieboard2 and A10-Lime. ROOT_NFS is enabled in sun4i_defconfig. GMAC is enabled in sun7i_defconfig for Cubietruck support. Also different localversion identifiers are set for sun4i and sun7i to avoid a possible clash between the names of directories with kernel modules.

[linux-sunxi] [PATCH 3.4] arm:sunxi:defconfig: Use performance cpufreq governor by default
A rather popular problem reported by new users on irc is very laggy performance out of the box. The default 'ondemand' governor is too slow to react on increased demand for processing power without extra tuning. The extra tuning needs extra efforts from the users. Not to mention that they have to be aware that such tuning might be necessary. One more reason not to use the 'ondemand' governor by default is that the power saving provided by it is not particularly good: https://www.mail-archive.com/linux-sunxi@googlegroups.com/msg00492.html https://www.mail-archive.com/linux-sunxi@googlegroups.com/msg00678.html http://www.cubieforums.com/index.php/topic,1413.msg8745.html#msg8745 It basically wastes a lot of performance for almost nothing. The most important defconfigs are sun4i_defconfig, sun5i_defconfig and sun7i_defconfig because they are mentioned in http://linux-sunxi.org/Linux_Kernel#Compilation Right now sun5i_defconfig does not even enable cpufreq and does not have any problems in the first place. This patch changes sun4i and sun7i defconfigs to have the following set of cpufreq governors: 1. 'performance' (default) 2. 'userspace' (for benchmarking purposes) 3.

Smells of custom Android romz and all that stuff to me, i.e. not the right way of doing things in the Linux land. If someone wants more power saving, after your patch they will need to make a conscious effort to switch to ondemand, and in the process of doing so they can also configure it to their liking just as easily. -- With respect, Roman signature.asc Description: PGP signature
