[RFC][FFT][Fixed-Point][NEON] NEON-Optimize
Hi Timothy, It requires some extra effort if twiddles and input/output have different bit width. Since Opus uses int32 for twiddles, we are going to do the same thing.

[RFC][FFT][Fixed-Point][NEON] NEON-Optimize
Hi Jean-Marc, I have implemented fixed-point FFT with 32-bit twiddles. Now I want to evaluate the accuracy, what method does Opus use? I use function implemented inside Ne10 to calculate SNR. Any comment? | size | SNR (dB) | | 16 | 82.558587 | | 32 | 83.530298 | | 60 | 80.292433 | | 64 | 82.752950 | | 120 | 79.625077 | | 128 | 83.091260 | | 240 | 79.555263 | | 256 |

Textures Twiddling/Swizzling
Thanks for the last info it was truely helpful. Anyways, I'm currently trying to implement 3D textures into yuzu, as far as I know they are twiddled in a different manner to 2D textures. Could one of you guys point me in the right direction? I've been meddling around: https://cgit.freedesktop.org/mesa/mesa/tree/src/gallium/drivers/nouveau/nv50/nv50_tex.c but I can't see where the

Add callback for twiddling DCT data
Hi, Attached is the first version of the DCT callback. It's still a bit WIP, but now you have something to refer to when I'm rambling :) Best Regards, Thorvald -------------- next part --------------

That being said, I agree that for Neon it makes sense to use 32-bit

Backing up from windows to macintosh
I want to backup from a windows machine to a Macintosh. All of the guides that I've seen describe the other direction. Worse, they all seem slightly different, or inconsistent. The first thing that I'd want to do should be simple: an rsync -az --delete of the entire drive, to back up all of the files. But that's not everything on the windows machine. And this is what I have not seen

sound driver advise needed
Hello-- How do I twiddle the sound drivers? I'm not that experienced with kernel twiddling and driver loading. I have Redhat 9. My previous attempts to play with the kernel and load extra drivers always ended with a new kernel that wouldn't boot. I know asterisk doesn't like to play with sound interfaces that aren't full duplex. So, when I built the system, I saw the MSI mot...

rspec runner setting $KCODE considered harmful?
...at change interpreter-wide behaviors? It reminds me of the bad days of perl when some distant code would unexpectedly change out your line terminator character on you. - It seems like a good idea to call out all the things the rspec environment changes that affect natural runtime behavior of code: twiddling of globals, class monkey patches, etc. It''d be great to get these into a list of publicly documented pitfalls for people to watch out for. Thanks for listening. Rspec has brought huge value to my engineering project and I really appreciate the tool! -Josh -------------- next part -------...

Gentoo on HP DL380 G6
Hi, i''am trying to build a Gentoo Dom0-kernel booting a HP DL380 G6. Has anyone twiddled a working kernel configuration for this hardware? i do have the linux-2.6.32-xen-r1 sources checked out by portage and tried some configurations.

[LLVMdev] Proposal for -filetype=obj full big endian support
Hi Jack, I would have expected the Mips backend to be using these routines (or more likely something on top of them) to emit the contents of the data and text sections and thus have the bit-twiddling done by these routines. I take it that's not happening? Basically, this should already work without any additional infrastructure. If it's not, something is broken and bypassing the mechanisms they should be using to output data. -Jim On Dec 20, 2011, at 12:21 PM, Carter, Jack wrote: &g...

[LLVMdev] Proposal for -filetype=obj full big endian support
Jim, I see routines that are already available to do the endianizing, but the data and text section contents don't have sizing for the individual elements as far as I can see so that I can endianize them. That is the part I am trying to solve, not the bit twiddling algorithm. Did I miss something?

Rather poor code optimisation of current clang/LLVM targeting Intel x86 (both -64 and -32)
Hi @ll, while clang/LLVM recognizes common bit-twiddling idioms/expressions like unsigned int rotate(unsigned int x, unsigned int n) { return (x << n) | (x >> (32 - n)); } and typically generates "rotate" machine instructions for this expression, it fails to recognize other also common bit-twiddling idioms/expressions. The st...

Small changes to big objects (2): Local Reference Classes
Back to the scenario in my email of Jan. 3: We have objects with some large (or very large) components and some other components as well. We need to modify the smaller stuff but are not changing the big data. How can we avoid copying the big data? (A use case might be some modeling of large data where we want to save various versions, all including the same original data but differing in

problme with scp, and suggestion for fix
I recently built openssh 2.1.1p1, under solaris. I noticed that I had problems running scp. It seems that it could not find the executable on the remote end. This was odd, becuase it existed in /usr/local/bin, publically executable, and /usr/local/bin/was in the users' normal PATH (exported, even). So finally, I twiddled the source to make it call /usr/local/bin/scp, instead of just

fxp multicast forwarding problems
...peated ... Attempted workarounds which don't work to un-wedge the chip: Reload the fxp0 microcode with "ifconfig fxp0 link0" Forcibly unloading the kernel module and reloading it Unpatching and repatching at the switch (a cheap 10/100 one) Enabling and disabling promiscuous mode Twiddling dev.fxp.0.noflow The link status looks fine, but the card will not send or receive traffic. A warm reboot was enough to get things back up again. regards, BMS

[Hivex] OS X and iconv

So, what would work in configure.ac to get Hivex to remove /usr/local/lib from the library paths for OS X, but just for iconv?

rebuilding anaconda for centos 4.0
Hi all: I'm trying to rebuild the anaconda installer for Centos 4.0 (i386) to add some RPMs and do some other things, and I've run into a problem. I've done lots of anaconda rebuilds for Tao Linux 1.0, and I'm bringing those bits forward into Centos 4.0. The all-knowing web hasn't turned up anything useful. It looks like the PXE-loaded kernel unpacked and mounted the
