[PATCH v4 0/1] Add sysfs interface to control class-of-service

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
