Subject: [PATCH v4 0/1] Add sysfs interface to control class-of-service
Date: Tue, 15 Oct 2019 03:31:28 -0400 [thread overview]
Message-ID: <20191015073129.2375-1-prathap.kumar.valsan@intel.com> (raw)
For GEN11 MOCS are part of context register state. This means updating
CLOS also needs to update the context state of active contexts.
v4:
- Make it explicit in the commit message that we want to set CLOS global
on device (Chris)
- Fixe the Locking (Chris)
- Move the global configuration of contexts away from gt.(Chris)
v3: Rebase
v2:
- Update the interface to use two sysfs files(Joonas)
- Gen12 PCode interface is not ready yet to read the way mask.
So removed TGL support and added support for Gen11.
- Updating MOCS in Gen 11 also require changing the context image of
existing contexts.
- Referred to gen8_configure_all_contexts() as suggested by Chris.
