[Bug 1234260] Re: Package and use 'intel_l3_parity' binary
To possibly clear up any confusion - the i915 driver will generate uevents (see the tool's udev listener for an example). These events are signs of parity errors in a specific part of the GPU's L3 cache. The tool itself allows remapping these bad locations. At a high level, it could work like: 1. HW detects paritity error, generates interrupt. 2. Kernel reports the uevent 3. udev rule receives the uevent, and information about the bad location (row, bank, subbank, slice). 4. udev either directly, or indirectly invokes intel_l3_parity to remap (disable; poorly named, I am sorry) that part of the cache. Please let me know if people still have confusion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1234260 Title: Package and use 'intel_l3_parity' binary To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1234260/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Too late for saucy, since we just released the betas.
