[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 02/15] Rename PSR sysctl/domctl interfaces and xsm policy to make them be general
This patch renames PSR sysctl/domctl interfaces and related xsm policy to
make them be general for all resource allocation features but not only
for CAT. Then, we can resuse the interfaces for all allocation features.
Basically, it changes 'cat' to 'alloc'. E.g.:
1. psr_cat_op -> psr_alloc_op
2. XEN_DOMCTL_psr_cat_op -> XEN_DOMCTL_psr_alloc_op
3. XEN_SYSCTL_psr_cat_op -> XEN_SYSCTL_psr_alloc_op
The sysctl/domctl version numbers are bumped.

v1:
- add description about what to be changed in commit message.
(suggested by Wei Liu)
- bump sysctl/domctl version numbers.
