| H A D | resctrl.h | diff e8f7282552b902af3bd1f07a87d657b7f5f12ab8 Wed Jul 28 12:06:26 CDT 2021 James Morse <james.morse@arm.com> x86/resctrl: Group staged configuration into a separate struct
When configuration changes are made, the new value is written to struct
rdt_domain's new_ctrl field and the have_new_ctrl flag is set. Later
new_ctrl is copied to hardware by a call to update_domains().
Once the CDP resources are merged, there will be one new_ctrl field in
use by two struct resctrl_schema requiring a per-schema IPI to copy the
value to hardware.
Move new_ctrl and have_new_ctrl into a new struct resctrl_staged_config.
Before the CDP resources can be merged, struct rdt_domain will need an
array of these, one per type of configuration. Using the type as an
index to the array will ensure that a schema configuration string can't
specify the same domain twice.
