Strange result in x265 test

Any chance of working ffmpeg support to use vp9 or any of the Hantro codecs?...

I've seen out of tree modules that patch the kernel source to make some macros and structure definitions visible to their code. I.e., move them out of...

It's not entirely clear to me if nvidia is saying you need the kernel source or the kernel headers. Both come from the same place: the kernel source....

But without those register headers, the code is still 75% larger than the Intel drm driver, which presumably also includes a considerable number of register...

I'm not an expert in amdgpu, but I did look at the code recently. I had a fix the BIOS in a XFX RX 560, which has broken UEFI support, so that it would...

After rebuilding with debug-install, the fps is back to the expected value. It must not have built correctly the first time. I've not reinstalled nasm,...

I tried debug-install to see what's going on. Nothing stood out as a problem:

My x265 result on a Ryzen 7 3700X system seems really out of whack. I get, quite consistently, 9.87 fps. Looking at the x265 results, it should be more...

My work in the automotive industry stopped back in 2014. At that time, the engine control unit was not Linux. Or at least it didn't look like Linux,...

No kidding. initramfs is not time efficient either. The entire FS must be uncompressed and loaded into the kernel buffer cache (RAM) before anything...

The most effort I ever put into optimizing Linux boot time was for a car radio. We needed to get the back-up camera working within 2 seconds of power...

`sleep 1h ; gcc Foo.c` benchmark took about an hour on each system tested, must be no difference!

That's kinda what's going on here. Most...
