[Xen-devel] [PATCH v8 11/16] tools: implement the new libxl get hw info interface

[Yi Sun]

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 redundant code in libxl_psr.c.

+## Memory Bandwidth Allocation (MBA)
+
+Memory Bandwidth Allocation (MBA) is a new feature available on Intel
+Skylake and later server platforms that allows an OS or Hypervisor/VMM to
+slow misbehaving apps/VMs by using a credit-based throttling mechanism. To
+enforce bandwidth on a specific domain, just set throttling value (THRTL)
+into Class of Service (COS). MBA provides two THRTL mode. One is linear mode
+and the other is non-linear mode.
+
+In the linear mode the input precision is defined as 100-(THRTL_MAX). Values
+not an even multiple of the precision (e.g., 12%) will be rounded down (e.g.,
+to 10% delay by the hardware).
+
+If linear values are not supported then input delay values are powers-of-two
+from zero to the THRTL_MAX value from CPUID. In this case any values not a 
power
+of two will be rounded down the next nearest power of two.
+
+For example, assuming a system with 2 domains:
+
+ * A THRTL of 0x0 for every domain means each domain can access the whole cache
+   without any delay. This is the default.
+
+ * Linear mode: Giving one domain a THRTL of 0xC and the other domain's 0 means
+   that the first domain gets 10% delay to access the cache and the other one
+   without any delay.
+
+ * Non-linear mode: Giving one domain a THRTL of 0xC and the other domain's 0
+   means that the first domain gets 8% delay to access the cache and the other
+   one without any delay.
+
+For more detailed information please refer to Intel SDM chapter
+"Introduction to Memory Bandwidth Allocation".
+
+In Xen's implementation, THRTL can be configured with libxl/xl interfaces but
+COS is maintained in hypervisor only. The cache partition granularity is per
+domain, each domain has COS=0 assigned by default, the corresponding THRTL is
+0, which means all the cache resource can be accessed without delay.
+
+### xl interfaces
+
+System MBA information such as maximum COS and maximum THRTL can be obtained 
by:
+
+`xl psr-hwinfo --mba`
+
+The simplest way to change a domain's THRTL from its default is running:
+
+`xl psr-mba-set  [OPTIONS]  `
+
+In a multi-socket system, the same thrtl will be set on each socket by default.
+Per socket thrtl can be specified with the `--socket SOCKET` option.
+
+Setting the THRTL may not be successful if insufficient COS is available. In
+such case unused COS(es) may be freed by setting THRTL of all related domains 
to
+its default value(0).
+
+Per domain THRTL settings can be shown

[Xen-devel] [PATCH v8 00/16] Enable Memory Bandwidth Allocation in Xen

[Yi Sun]

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:

This version bases on below pre-fix patch which has been merged into staging

[Xen-devel] [PATCH v8 14/16] tools: implement new generic get value interface and MBA get value command

[Yi Sun]

This patch implements generic get value interfaces in libxc and libxl.
It also refactors the get value flow in xl to make it be suitable for all
allocation features. Based on that, a new MBA get value command is added in xl.

+# Overview
+
+The Memory Bandwidth Allocation (MBA) feature provides indirect and approximate
+control over memory bandwidth available per-core. This feature provides OS/
+hypervisor the ability to slow misbehaving apps/domains by using a credit-based
+throttling mechanism.
+
+# User details
+
+* Feature Enabling:
+
+  Add "psr=mba" to boot line parameter to enable MBA feature.
+
+* xl interfaces:
+
+  1. `psr-mba-show [domain-id|domain-name]`:
+
+ Show memory bandwidth throttling for domain. Under different modes, it
+ shows different type of data.
+
+ There are two modes:
+ Linear mode: the input precision is defined as 100-(MBA_MAX). For 
instance,
+ if the MBA_MAX value is 90, the input precision is 10%. Values not an even
+ multiple of the precision (e.g., 12%) will be rounded down (e.g., to 10%
+ delay applied) by HW automatically. The response of throttling value is
+ linear.
+

[Xen-devel] [PATCH v8 02/16] Rename PSR sysctl/domctl interfaces and xsm policy to make them be general

[Yi Sun]

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 'psr_cat_op' to 'psr_alloc', and remove 'CAT_' from some
macros. E.g.:
1. psr_cat_op -> psr_alloc
2. XEN_DOMCTL_psr_cat_op -> XEN_DOMCTL_psr_alloc
3. XEN_SYSCTL_psr_cat_op -> XEN_SYSCTL_psr_alloc
4. XEN_DOMCTL_PSR_CAT_SET_L3_CBM -> XEN_DOMCTL_PSR_SET_L3_CBM
5. XEN_SYSCTL_PSR_CAT_get_l3_info -> XEN_SYSCTL_PSR_get_l3_info

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

[Xen-devel] [PATCH v8 05/16] x86: implement data structure and CPU init flow for MBA

[Yi Sun]

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 register of MBA stores a throttle value for one or more
domains. The throttle value means the delay applied to traffic between
L2 cache and next cache level.

This patch also implements init flow for MBA and register stub
callback functions.

[Xen-devel] [PATCH v6] x86/altp2m: Added xc_altp2m_set_mem_access_multi()

[petre . pircalabu]

From: Razvan Cojocaru 

For the default EPT view we have xc_set_mem_access_multi(), which
is able to set an array of pages to an array of access rights with
a single hypercall. However, this functionality was lacking for the
altp2m subsystem, which could only set page restrictions for one
page at a time. This patch addresses the gap.

HVMOP_altp2m_set_mem_access_multi has been added as a HVMOP (as opposed to a
DOMCTL) for consistency with its HVMOP_altp2m_set_mem_access counterpart (and
hence with the original altp2m design, where domains are allowed - with the
proper altp2m access rights - to alter these settings), in the absence of an
official position on the issue from the original altp2m designers.

Changed since v2:
* Added support for compat arguments translation

Changed since v3:
* Replaced  __copy_to_guest with __copy_field_to_guest
* Removed the un-needed parentheses.
* Fixed xlat.lst ordering
* Added comment to patch description explaining why the
functionality was added as an HVMOP.
* Guard using XEN_GENERATING_COMPAT_HEADERS the hvmmem_type_t definition.
This will prevent suplicate definitions to be generated for the
compat equivalent.
* Added comment describing the manual translation of
xen_hvm_altp2m_op_t generic fields from compat_hvm_altp2m_op_t.

Changed since v4:
* Changed the mask parameter to 0x3F.
* Split long lines.
* Added "improperly named HVMMEM_(*)" to the comment explaining the
XEN_GENERATING_COMPAT_HEADERS guard.
* Removed typedef and XEN_GUEST_HANDLE for 
xen_hvm_altp2m_set_mem_access_multi.
* Copied the "opaque" field to guest in compat_altp2m_op.
* Added build time test to check if the size of
xen_hvm_altp2m_set_mem_access_multi at least equal to the size of
compat_hvm_altp2m_set_mem_access_multi.

Changed since v5:
* Changed the domid parameter type to uint32_t to match 5b42c82f.
* Added comment to explain why the 0x3F value was chosen.
* Fixed switch indentation in compat_altp2m_op.
* Changed the condition used to check if the opaque field has to
be copied to the guest.
* Added CHECK_hvm_altp2m_op and CHECK_hvm_altp2m_set_mem_access_multi.
