2019-10-08RDMA/srp: Add parse function for maximum initiator to target IU sizeHonggang Li1-0/+2
According to SRP specifications 'srp-r16a' and 'srp2r06', IOControllerProfile attributes for SRP target port include the maximum initiator to target IU size. SRP connection daemons, such as srp_daemon, can get the value from the subnet manager. The SRP connection daemon can pass this value to kernel. This patch adds a parse function for it. Upstream commit [1] enables the kernel parameter, 'use_imm_data', by default. [1] also use (8 * 1024) as the default value for kernel parameter 'max_imm_data'. With those default values, the maximum initiator to target IU size will be 8260. In case the SRPT modules, which include the in-tree 'ib_srpt.ko' module, do not support SRP-2 'immediate data' feature, the default maximum initiator to target IU size is significantly smaller than 8260. For 'ib_srpt.ko' module, which built from source before [2], the default maximum initiator to target IU is 2116. [1] introduces a regression issue for old srp targets with default kernel parameters, as the connection will be rejected because of a too large maximum initiator to target IU size.

2019-10-04drivers/tty/serial/8250: Make Aspeed VUART SIRQ polarity configurableOskar Senft1-1/+10
Make the SIRQ polarity for Aspeed AST24xx/25xx VUART configurable via sysfs. This setting need to be changed on specific host platforms depending on the selected host interface (LPC / eSPI). The setting is configurable via sysfs rather than device-tree to stay in line with other related configurable settings. On AST2500 the VUART SIRQ polarity can be auto-configured by reading a bit from a configuration register, e.g. the LPC/eSPI interface configuration bit. Tested: Verified on TYAN S7106 mainboard.

Besides that, the regression with backlight being permanently off on various EeePC laptops has been fixed. - Accelerometer on HP ProBook 450 G0 shows wrong measurements due to X axis being inverted. This has been fixed. - Intel PMC core driver has been extended to be ACPI enumerated if the DSDT provides device with _HID "INT33A1". This allows to convert the driver to be pure platform and support new hardware purely based on ACPI DSDT. - From now on the Intel Speed Select Technology is supported thru a corresponding driver. This driver provides an access to the features of the ISST, such as Performance Profile, Core Power, Base frequency and Turbo Frequency. - Mellanox platform drivers has been refactored and now extended to support more systems, including new coming ones. - The OLPC XO-1.75 platform is now supported. - CB4063 Beckhoff Automation board is using PMC clocks, provided via pmc_atom driver, for ethernet controllers in a way that they can't be managed by the clock driver. The quirk has been extended to cover this case. - Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile the information of Chuwi Hi10 Air has been fixed to cover more models based on the same platform. - Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it has been provided. It required some extension of the generic WMI library, which allows to propagate opaque context to the ->probe() of the individual drivers.

2019-04-25nvmem: core: add NVMEM_SYSFS KconfigSrinivas Kandagatla1-0/+2
Many nvmem providers are not very keen on having default sysfs nvmem entry, as most of the usecases for them are inside kernel itself. And in some cases read/writes to some areas in nvmem are restricted and trapped at secure monitor level, so accessing them from userspace would result in board reboots. This patch adds new NVMEM_SYSFS Kconfig to make binary sysfs entry an optional one. This provision will give more flexibility to users. This patch also moves existing sysfs code to a new file so that its not compiled in when its not really required.

2019-04-04node: Add memory-side caching attributesKeith Busch1-0/+34
System memory may have caches to help improve access speed to frequently requested address ranges. While the system provided cache is transparent to the software accessing these memory ranges, applications can optimize their own access based on cache attributes. Provide a new API for the kernel to register these memory-side caches under the memory node that provides it. The new sysfs representation is modeled from the existing cpu cacheinfo attributes, as seen from /sys/devices/system/cpu/<cpu>/cache/. Unlike CPU cacheinfo though, the node cache level is reported from the view of the memory. A higher level number is nearer to the CPU, while lower levels are closer to the last level memory. The exported attributes are the cache size, the line size, associativity indexing, and write back policy, and add the attributes for the system memory caches to sysfs stable documentation.

2019-04-04node: Add heterogenous memory access attributesKeith Busch1-0/+28
Heterogeneous memory systems provide memory nodes with different latency and bandwidth performance attributes. Provide a new kernel interface for subsystems to register the attributes under the memory target node's initiator access class. If the system provides this information, applications may query these attributes when deciding which node to request memory. The following example shows the new sysfs hierarchy for a node exporting performance attributes: # tree -P "read*|write*"/sys/devices/system/node/nodeY/accessZ/initiators/ /sys/devices/system/node/nodeY/accessZ/initiators/ |-- read_bandwidth |-- read_latency |-- write_bandwidth `-- write_latency The bandwidth is exported as MB/s and latency is reported in nanoseconds. The values are taken from the platform as reported by the manufacturer. Memory accesses from an initiator node that is not one of the memory's access "Z" initiator nodes linked in the same directory may observe different performance than reported here. When a subsystem makes use of this interface, initiators of a different access number may not have the same performance relative to initiators in other access numbers, or omitted from the any access class' initiators. Descriptions for memory access initiator performance access attributes are added to sysfs stable documentation.

2019-04-04node: Link memory nodes to their compute nodesKeith Busch1-1/+24
Systems may be constructed with various specialized nodes. Some nodes may provide memory, some provide compute devices that access and use that memory, and others may provide both. Nodes that provide memory are referred to as memory targets, and nodes that can initiate memory access are referred to as memory initiators. Memory targets will often have varying access characteristics from different initiators, and platforms may have ways to express those relationships. In preparation for these systems, provide interfaces for the kernel to export the memory relationship among different nodes memory targets and their initiators with symlinks to each other. If a system provides access locality for each initiator-target pair, nodes may be grouped into ranked access classes relative to other nodes. The new interface allows a subsystem to register relationships of varying classes if available and desired to be exported. A memory initiator may have multiple memory targets in the same access class. The target memory's initiators in a given class indicate the nodes access characteristics share the same performance relative to other linked initiator nodes. Each target within an initiator's access class, though, do not necessarily perform the same as each other. A memory target node may have multiple memory initiators. All linked initiators in a target's class have the same access characteristics to that target. The following example show the nodes' new sysfs hierarchy for a memory target node 'Y' with access class 0 from initiator node 'X': # symlinks -v /sys/devices/system/node/nodeX/access0/ relative: /sys/devices/system/node/nodeX/access0/targets/nodeY -> ../../nodeY # symlinks -v /sys/devices/system/node/nodeY/access0/ relative: /sys/devices/system/node/nodeY/access0/initiators/nodeX -> ../../nodeX The new attributes are added to the sysfs stable documentation.

2019-03-20Drivers: hv: vmbus: Expose monitor data only when monitor pages are usedKimberly Brown1-3/+9
There are two methods for signaling the host: the monitor page mechanism and hypercalls. The monitor page mechanism is used by performance critical channels (storage, networking, etc.) because it provides improved throughput. However, latency is increased. Monitor pages are allocated to these channels. Monitor pages are not allocated to channels that do not use the monitor page mechanism. Therefore, these channels do not have a valid monitor id or valid monitor page data. In these cases, some of the "_show" functions return incorrect data. They return an invalid monitor id and data that is beyond the bounds of the hv_monitor_page array fields. The "channel->offermsg.monitor_allocated" value can be used to determine whether monitor pages have been allocated to a channel. Add "is_visible()" callback functions for the device-level and channel-level attribute groups. These functions will hide the monitor sysfs files when the monitor mechanism is not used. Remove ".default_attributes" from "vmbus_chan_attrs" and create a channel-level attribute group. These changes allow the new "is_visible()" callback function to be applied to the channel-level attributes. Call "sysfs_create_group()" in "vmbus_add_channel_kobj()" to create the channel's sysfs files. Add a new function, “vmbus_remove_channel_attr_group()”, and call it in "free_channel()" to remove the channel's sysfs files when the channel is closed.

2019-02-14Drivers: hv: vmbus: Expose counters for interrupts and full conditionsKimberly Brown1-0/+33
Counter values for per-channel interrupts and ring buffer full conditions are useful for investigating performance. Expose counters in sysfs for 2 types of guest to host interrupts: 1) Interrupts caused by the channel's outbound ring buffer transitioning from empty to not empty 2) Interrupts caused by the channel's inbound ring buffer transitioning from full to not full while a packet is waiting for enough buffer space to become available Expose 2 counters in sysfs for the number of times that write operations encountered a full outbound ring buffer: 1) The total number of write operations that encountered a full condition 2) The number of write operations that were the first to encounter a full condition Increment the outbound full condition counters in the hv_ringbuffer_write() function because, for most drivers, a full outbound ring buffer is detected in that function. Also increment the outbound full condition counters in the set_channel_pending_send_size() function. In the hv_sock driver, a full outbound ring buffer is detected and set_channel_pending_send_size() is called before hv_ringbuffer_write() is called. I tested this patch by confirming that the sysfs files were created and observing the counter values. The values seemed to increase by a reasonable amount when the Hyper-v related drivers were in use.

2018-09-14xen/balloon: add runtime control for scrubbing ballooned out pagesMarek Marczykowski-Górecki1-0/+9
Scrubbing pages on initial balloon down can take some time, especially in nested virtualization case (nested EPT is slow). When HVM/PVH guest is started with memory= significantly lower than maxmem=, all the extra pages will be scrubbed before returning to Xen. But since most of them weren't used at all at that point, Xen needs to populate them first (from populate-on-demand pool). In nested virt case (Xen inside KVM) this slows down the guest boot by 15-30s with just 1.5GB needed to be returned to Xen. Add runtime parameter to enable/disable it, to allow initially disabling scrubbing, then enable it back during boot (for example in initramfs). Such usage relies on assumption that a) most pages ballooned out during initial boot weren't used at all, and b) even if they were, very few secrets are in the guest at that time (before any serious userspace kicks in). Convert CONFIG_XEN_SCRUB_PAGES to CONFIG_XEN_SCRUB_PAGES_DEFAULT (also enabled by default), controlling default value for the new runtime switch.
