The New Features & Exciting Changes Of The Linux 4.10 Kernel

Right, but whenever I read tests about BFQ it's always doing something alongside of heavy writing, hence I wondered if what BFQ was tackling was just the symptoms of the writeback issue.

Thank you!

There are some more details on http://algo.ing.unimo.it/people/paol...d/mst-2015.pdf (search for "async"). I think that even BFQ will benefit from better controlling of the rate at which asynchronous writes are generated.

Great link again, thank you!

Perhaps the writeback throttling changes are worth mentioning: https://lwn.net/Articles/682582/

I wanted to test kernel 4.10 because of the automatic throttling of writeback queues on the block side. In fact with 4.8.13 every time I copy big files to my usb stick the system becomes unresponsive.
Unfortunately with 4.10 when I try to write the Arch image to an usb stick using "sudo dd if=archlinux-2016.12.01-dual.iso of=/dev/sdb bs=1 status=progress" it instantly finishes (like when you write to the cache but you still have to sync). It wrote something to the stick, but the image doesn't boot. Manually syncing does not help. Everything works flawlessly with kernel 4.8.

This is the bug report: https://bugzilla.kernel.org/show_bug.cgi?id=191391

not going to happen. World does not stand still and projects evolve with it.

My attempt at humor FAILED! FAILED I say...

Wow. So kernel 4.10 and still no GCN 1.1 support for my supposedly top of the line, and expensive, R9 390? I'm a digital design engineer, and am known to be quite patient and understanding when it comes to technical issues, but at this point I have to say my frustration has given over to the realization that my card will forever be my most expensive paperweight. It's truly stunning that Linux and/or AMD, and I don't care where people want to lay the fault, completely dissolved support for multiple lines of a major vendors GPUs. And it was done simultaneously with a major push by Valve to market Steam machines as the first viable Linux gaming machines. What an incredible disappointment, and loss of opportunity for Linux to finally break into mainstream gaming. I think someone said it best earlier, if support ever does come for these cards it will be in years, long past their prime. At this point I have to say that the incompetence and lack of planning on all sides is mind boggling.

What makes you think that your graphics card wasn't supported by radeon/radeonsi?
