[Xen-devel] [PATCH v7 04/16] x86: a few optimizations to psr codes

This patch refines psr codes: 1. Change type of 'cat_init_feature' to 'bool' to remove the pointless returning of error code. 2. Move printk in 'cat_init_feature' to reduce a return path. 3. Define a local variable 'feat_mask' in 'psr_cpu_init' to reduce calling of 'cpuid_count_leaf()'. 4.

[Xen-devel] [PATCH v7 11/16] tools: implement the new libxl get hw info interface

This patch implements the new libxl get hw info interface, 'libxl_psr_get_hw_info', which is suitable to all psr allocation features. It also implements corresponding list free function, 'libxl_psr_hw_info_list_free' and makes 'libxl_psr_cat_get_info' call 'libxl_psr_get_hw_info' to avoid

[Xen-devel] [PATCH v7 05/16] x86: implement data structure and CPU init flow for MBA

This patch implements main data structures of MBA. Like CAT features, MBA HW info has cos_max which means the max thrtl register number, and thrtl_max which means the max throttle value (delay value). It also has a flag to represent if the throttle value is linear or non-linear. One thrtl

[Xen-devel] [PATCH v7 00/16] Enable Memory Bandwidth Allocation in Xen

Hi, all, We plan to bring a new PSR (Platform Shared Resource) feature called Intel Memory Bandwidth Allocation (MBA) to Xen. Besides the MBA enabling, we change some interfaces to make them more general but not only for CAT. Any comments are welcome! You can find this series at:

[Xen-devel] [PATCH v7 02/16] Rename PSR sysctl/domctl interfaces and xsm policy to make them be general
