Subject: [PATCH v2 14/24] x86/resctrl: Rename update_domains() resctrl_arch_update_domains()
Date: Fri, 12 Mar 2021 17:58:39 +0000 [thread overview]
Message-ID: <20210312175849.8327-15-james.morse@arm.com> (raw)
In-Reply-To: <20210312175849.8327-1-james.morse@arm.com>
update_domains() merges the staged configuration changes into the
arch codes configuration array. Rename to make it clear its part of the
arch code interface to resctrl.
Reviewed-by: Jamie Iles <jamie@nuviainc.com>
Signed-off-by: James Morse <james.morse@arm.com>

Changes since v1:
* The closid is no longer staged as from resctrl its always going to be
the same number even with CDP.
