Subject: [PATCH v3 14/15] tools: implement new generic set value interface and MBA set value command
Date: Tue, 5 Sep 2017 17:32:36 +0800 [thread overview]
Message-ID: <1504603957-5389-15-git-send-email-yi.y.sun@linux.intel.com> (raw)
In-Reply-To: <1504603957-5389-1-git-send-email-yi.y.sun@linux.intel.com>
This patch implements new generic set value interfaces in libxc and libxl.
These interfaces are suitable for all allocation features. It also adds a
new MBA set value command in xl.
Signed-off-by: Yi Sun <yi.y.sun@linux.intel.com>
---
v3:
- add 'const' for 'opts[]' in 'main_psr_mba_set'.
(suggested by Roger Pau Monné)
- replace 'libxl_psr_cbm_type' to 'libxl_psr_type' for newly defined
interfaces.
(suggested by Roger Pau Monné)
