Hi, Sometime ago i finished a port of Ogg Vorbis to Playstation 2. The code is working just fine and the music sounds like it should, but there is one problem. I get CPU usage that looks like this (when i say frames i mean actually rendering frames on the Playstations 2 and you have 50 or 60 frames per second) cpu usage: ~100% ~0% ~0% 0% ~100% current

Add some kind of vblank workers. The interface is similar to regular delayed works, and is mostly based off kthread_work. It allows for scheduling delayed works that execute once a particular vblank sequence has passed. It also allows for accurate flushing of scheduled vblank works - in that flushing waits for both the...

From: Lyude Paul <lyude at redhat.com> Nouveau has finally gotten CRC support, hooray! Well, it's under review at least: https://patchwork.freedesktop.org/series/74804/ (it has a cover letter, but nouveau's mailing list configuration has blocked the email so I'm waiting for a moderator to fix that) So, this series adds the relevant tests for it since nvidia's CRC

From: Lyude Paul <lyude at redhat.com> Nouveau has finally gotten CRC support, and at this point that support has made its way upstream. Hooray! So, let's start adding some relevant tests for it since nvidia's CRC implementation has some rather interesting design choices that needed to be worked around. Lyude Paul (5): lib/igt_core: Fix igt_assert_fd() documentation

...s implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up with: vblank workers. Basically, this is just a generic DRM interface that allows for scheduling high-priority workers that start on a given vblank interrupt. Note that while we're currently only using this in nouveau, Intel has plans to use this for i915 as well (hence why they came up with it!). And f...
