2018-01-18x86/intel_rdt: Add command line parameter to control L2_CDPFenghua Yu1-1/+2

L2 and L3 Code and Data Prioritization (CDP) can be enabled separately. The existing mount parameter "cdp" is only for enabling L3 CDP and will be kept for backwards compability.

2018-01-17dm: add unstriped targetScott Bauer1-0/+124
This device mapper "unstriped" target remaps and unstripes I/O so it is issued solely on a single drive in a HW RAID0 or dm-striped target. In a 4 drive HW RAID0 the striped target exposes 1/4th of the LBA range as a virtual drive. Each I/O to that virtual drive will only be issued to the 1 drive that was selected of the 4 drives in the HW RAID0. This unstriped target is most useful for Intel NVMe drives that have multiple cores but that do not have firmware control to pin separate LBA ranges to each discrete cpu core.

2018-01-16cgroup, docs: document the root cgroup behavior of cpu and io controllersMaciej S. Szmigiero1-1/+35
Currently, cgroups v2 documentation contains only a generic remark that "How resource consumption in the root cgroup is governed is up to each controller", which isn't really telling users much, who need to dig in the code and / or commit messages to learn the exact behavior. In cgroups v1 at least the blkio controller had its operation with respect to competition between child threads and child cgroups documented in blkio-controller.txt, with references to cfq-iosched.txt. Also, cgroups v2 documentation describes v1 behavior of both cpu and blkio controllers in an "Issues with v1" section. Let's document this behavior also for cgroups v2 to make life easier for users.

2018-01-15raid5-ppl: PPL support for disks with write-back cache enabledTomasz Majchrzak1-3/+4
In order to provide data consistency with PPL for disks with write-back cache enabled all data has to be flushed to disks before next PPL entry. The disks to be flushed are marked in the bitmap. It's modified under a mutex and it's only read after PPL io unit is submitted. A limitation of 64 disks in the array has been introduced to keep data structures and implementation simple. RAID5 arrays with so many disks are not likely due to high risk of multiple disks failure. Such restriction should not be a real life limitation. With write-back cache disabled next PPL entry is submitted when data write for current one completes. Data flush defers next log submission so trigger it when there are no stripes for handling found. As PPL assures all data is flushed to disk at request completion, just acknowledge flush request when PPL is enabled.

2018-01-14arm64: cpu_errata: Add Kryo to Falkor 1003 errataStephen Boyd1-1/+1
The Kryo CPUs are also affected by the Falkor 1003 errata, so we need to do the same workaround on Kryo CPUs. The MIDR is slightly more complicated here, where the PART number is not always the same when looking at all the bits from 15 to 4. Drop the lower 8 bits and just look at the top 4 to see if it's '2' and then consider those as Kryo CPUs. This covers all the combinations without having to list them all out.

Only try to enable a 64-bit window on AMD CPUs when "pci=big_root_window" is specified. This taints the kernel because the new 64-bit window uses address space we don't know anything about, and it may contain unreported devices or memory that would conflict with the window. The pci_amd_enable_64bit_bar() quirk that enables the window is specific to AMD CPUs. The generic solution would be to have the firmware enable the window and describe it in the host bridge's _CRS method, or at least describe it in the _PRS method so the OS would have the option of enabling it.
