PCI: Update "pci=resource_alignment" documentation
Some uio based PCI drivers, e.g., uio_cif, do not work if the assigned PCI memory resources are not page aligned. By using the kernel option "pci=resource_alignment=<align>@<bus>:<slot>.<func>" it is possible to request page alignment for memory resources of devices. However, this is cumbersome when using several devices, and the bus/slot/func addresses may change if devices are added to or removed from the system. Extend the "pci=resource_alignment" option so we can specify the relevant devices via PCI vendor, device, subvendor, and subdevice IDs. The specification of the devices via IDs is indicated by a leading string "pci:" as argument to "pci=resource_alignment". The format of the specification is pci:<vendor>:<device>[:<subvendor>:<subdevice>] Examples: pci=resource_alignment=4096@pci:8086:9c22:103c:198f pci=resource_alignment=pci:8086:9c22 # defaults to PAGE_SIZE align [bhelgaas: changelog, use actual vendor/device IDs in examples] Signed-off-by: Mathias Koehrer <mathias.koehrer@etas.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

Highlights:
Trond made a change to the server's tcp logic that allows a fast client to better take advantage of high bandwidth networks, but may increase the risk that a single client could starve other clients; a new sunrpc.svc_rpc_per_connection_limit parameter should help mitigate this in the (hopefully unlikely) event this becomes a problem in practice. Tom Haynes added a minimal flex-layout pnfs server, which is of no use in production for now--don't build it unless you're doing client testing or further server development. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXo7HNAAoJECebzXlCjuG+zqUP/RxO5jZjBhNI8/ayGdDW/Jnq s0Fu6B+aNRV3GnugmIeI4tWNGnPyERNzFtjLKlnwaasz/oW4qBLqGbNUWC5xKARS erODs0hM/1aCYWwNBEc5qXP2u23HrWVuQ+B5fg42ACyliKFGq5faDRmf6XGU/1kB 8unXGWPAiLiNZD/bWP91fYhThlLgpfHBFZ7M3G2IqmzWZTSELPzwp1bpRWt7yWQQ z1oYtXToycbwz3yPVk3cXtaoqpjDUVZf2Guqgqi1BwEyEtYOSaYo1VHNsKDf4OId QXQh64AqIK4uszpvtNhvsEaAECN7IiB+N4n2laFiQVmAf8Hfl3AnV/gKeD4lKmTj TY6knnjZO/X88wn80MB7JR1H1WXvvzNIHwNR95qfub/lVKX+C+0AORRtYhi5F9ec ixNs/z1ImLpYxAjiP/T5anD5xcX2S+LcSv7kRjhEufqNFtRAIqBZO9ZWbCdXAAyE tcH9Cru4jeIlFO/y6O61EVrn9FFj2+0uu+7urefNRQ2Y9pmKeculJrLF6WO8WHms 4IzXMmjZK+358RVdX2Ji5Hw6rBDvfgP+LjB8Jn8CeIiNRONEjT+2/AYQcfk61aLb INUbk6G6Vfd8iMO4aaRI9tmW+vKCOZa0IbnrNE1oHKp/AKBDr25i5YPSCsnl3r4Q iR7rRe9FIkfqBpbfjVFv =mo54 -----END PGP SIGNATURE----- Merge tag 'nfsd-4.8' of git://linux-nfs.org/~bfields/linux Pull nfsd updates from Bruce Fields: "Highlights: - Trond made a change to the server's tcp logic that allows a fast client to better take advantage of high bandwidth networks, but may increase the risk that a single client could starve other clients; a new sunrpc.svc_rpc_per_connection_limit parameter should help mitigate this in the (hopefully unlikely) event this becomes a problem in practice. - Tom Haynes added a minimal flex-layout pnfs server, which is of no use in production for now--don't build it unless you're doing client testing or further server development" * tag 'nfsd-4.8' of git://linux-nfs.org/~bfields/linux: (32 commits) nfsd: remove some dead code in nfsd_create_locked() nfsd: drop unnecessary MAY_EXEC check from create nfsd: clean up bad-type check in nfsd_create_locked nfsd: remove unnecessary positive-dentry check nfsd: reorganize nfsd_create nfsd: check d_can_lookup in fh_verify of directories nfsd: remove redundant zero-length check from create nfsd: Make creates return EEXIST instead of EACCES SUNRPC: Detect immediate closure of accepted sockets SUNRPC: accept() may return sockets that are still in SYN_RECV nfsd: allow nfsd to advertise multiple layout types nfsd: Close race between nfsd4_release_lockowner and nfsd4_lock nfsd/blocklayout: Make sure calculate signature/designator length aligned xfs: abstract block export operations from nfsd layouts SUNRPC: Remove unused callback xpo_adjust_wspace() SUNRPC: Change TCP socket space reservation SUNRPC: Add a server side per-connection limit SUNRPC: Micro optimisation for svc_data_ready SUNRPC: Call the default socket callbacks instead of open coding SUNRPC: lock the socket while detaching it ... |

modules: Add kernel parameter to blacklist modules
Blacklisting a module in linux has long been a problem. The current procedure is to use rd.blacklist=module_name, however, that doesn't cover the case after the initramfs and before a boot prompt (where one is supposed to use /etc/modprobe.d/blacklist.conf to blacklist runtime loading). Using rd.shell to get an early prompt is hit-or-miss, and doesn't cover all situations AFAICT. This patch adds this functionality of permanently blacklisting a module by its name via the kernel parameter module_blacklist=module_name. [v2]: Rusty, use core_param() instead of __setup() which simplifies things. [v3]: Rusty, undo wreckage from strsep() [v4]: Rusty, simpler version of blacklisted() Signed-off-by: Prarit Bhargava <prarit@redhat.com> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: linux-doc@vger.kernel.org Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> |

printk: add kernel parameter to control writes to /dev/kmsg
Add a "printk.devkmsg" kernel command line parameter which controls how userspace writes into /dev/kmsg. It has three options: * ratelimit - ratelimit logging from userspace. * on - unlimited logging from userspace * off - logging from userspace gets ignored The default setting is to ratelimit the messages written to it. This changes the kernel default setting of "on" to "ratelimit" and we do that because we want to keep userspace spamming /dev/kmsg to sane levels. This is especially moot when a small kernel log buffer wraps around and messages get lost. So the ratelimiting setting should be a sane setting where kernel messages should have a bit higher chance of survival from all the spamming. It additionally does not limit logging to /dev/kmsg while the system is booting if we haven't disabled it on the command line. Furthermore, we can control the logging from a lower priority sysctl interface - kernel.printk_devkmsg. That interface will succeed only if printk.devkmsg *hasn't* been supplied on the command line. If it has, then printk.devkmsg is a one-time setting which remains for the duration of the system lifetime. This "locking" of the setting is to prevent userspace from changing the logging on us through sysctl(2). This patch is based on previous patches from Linus and Steven.

Some big changes this month, headlined by the addition of a new formatted
documentation mechanism based on the Sphinx system. The objectives here are to make it easier to create better-integrated (and more attractive) documents while (eventually) dumping our one-of-a-kind, cobbled-together system for something that is widely used and maintained by others. There's a fair amount of information what's being done, why, and how to use it in: https://lwn.net/Articles/692704/ https://lwn.net/Articles/692705/ Closer to home, Documentation/kernel-documentation.rst describes how it works. For now, the new system exists alongside the old one; you should soon see the GPU documentation converted over in the DRM pull and some significant media conversion work as well. Once all the docs have been moved over and we're convinced that the rough edges (of which are are a few) have been smoothed over, the DocBook-based stuff should go away. Primary credit is to Jani Nikula for doing the heavy lifting to make this stuff actually work; there has also been notable effort from Markus Heiser, Daniel Vetter, and Mauro Carvalho Chehab. Expect a couple of conflicts on the new index.rst file over the course of the merge window; they are trivially resolvable. That file may be a bit of a conflict magnet in the short term, but I don't expect that situation to last for any real length of time. Beyond that, of course, we have the usual collection of tweaks, updates, and typo fixes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJXlT8bAAoJEI3ONVYwIuV6IF0QAM7qpEgAveXgwzGr18ReftjB ryyPXdLNX8R7fQkUAu85Znlw93k4+7QxHseBgZ1I3t9IhjvzemidOKfj96SJ0DVE zco5FUTO1TPfO2uG8asNzlXSrwktrEZoFTraRIYpCjAAimg/UEQAM4xgNOJfmW39 8eLg6dhnzqnfCH6M+Q7AZPLmqNSOfA2qNFqHNs7VCbwjLQC0l4yw4PHOsdX0QhCL NtlukHOhB4CwaELDl6lZOQgnz79e4pDljFd/wA/vVpdq7ev8NnOgVVt93M2fUvLX Bdfzo2OtZg7LJnWtpQl2LJq2MJJdOmgIw+ls6cB5gvxV3+CCIndE/6IIbimC/lZi DiaaqVU/EV3AemBDbqErO4k3ZvMT2ZTaSx1OQoLpIwNAsAkEOkb+t2hcwrTqhxg1 kEIXEEboXwStBtH3iar2YiGHQWUhia4mxfv5n4Dvamaca4tGWXHWxSRjbRcaJ1ef v1kt6ymjwr2sd9116EUxngfYONwlrhk5F87D/dC2eQzEyS0z7+F8wWb/h2gsAaU1 6oVCoQjTe2KAc/7dHINMSIjg2TfVfHS5XIhWu5z6wyxRb8ey9QuKLQYlOTV/L3Ms aR4O6qvDIsIbOvEd+hHSIbeG7JOPd0LdSI4tdo4d9kquW2OJ6TmmOr/ihbJt430v s/Qxqwgme/8DJd3KcV6j =4fDK -----END PGP SIGNATURE----- Merge tag 'docs-for-linus' of git://git.lwn.net/linux Pull documentation updates from Jonathan Corbet: "Some big changes this month, headlined by the addition of a new formatted documentation mechanism based on the Sphinx system.

Pull s390 updates from Martin Schwidefsky: "There are a couple of new things for s390 with this merge request: - a new scheduling domain "drawer" is added to reflect the unusual topology found on z13 machines. Performance tests showed up to 8 percent gain with the additional domain. - the new crc-32 checksum crypto module uses the vector-galois-field multiply and sum SIMD instruction to speed up crc-32 and crc-32c. - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in the generic vmlinux.lds linker script definitions. - kcov instrumentation support. A prerequisite for that is the inline assembly basic block cleanup, which is the reason for the net/iucv/iucv.c change. - support for 2GB pages is added to the hugetlbfs backend. Then there are two removals: - the oprofile hardware sampling support is dead code and is removed. The oprofile user space uses the perf interface nowadays. - the ETR clock synchronization is removed, this has been superseeded be the STP clock synchronization.

PCI: Allow additional bus numbers for hotplug bridges
A user may hot add a switch requiring more than one bus to enumerate. This previously required a system reboot if BIOS did not sufficiently pad the bus resource, which they frequently don't do. Add a kernel parameter so a user can specify the minimum number of bus numbers to reserve for a hotplug bridge's subordinate buses so rebooting won't be necessary. The default is 1, which is equivalent to previous behavior. Signed-off-by: Keith Busch <keith.busch@intel.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PM / hibernate: Image data protection during restoration
Make it possible to protect all pages holding image data during hibernate image restoration by setting them read-only (so as to catch attempts to write to those pages after image data have been stored in them). This adds overhead to image restoration code (it may cause large page mappings to be split as a result of page flags changes) and the errors it protects against should never happen in theory, so the feature is only active after passing hibernate=protect_image to the command line of the restore kernel. Also it only is built if CONFIG_DEBUG_RODATA is set. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

efi / ACPI: load SSTDs from EFI variables
This patch allows SSDTs to be loaded from EFI variables. It works by specifying the EFI variable name containing the SSDT to be loaded. All variables with the same name (regardless of the vendor GUID) will be loaded. Note that we can't use acpi_install_table and we must rely on the dynamic ACPI table loading and bus re-scanning mechanisms. That is because I2C/SPI controllers are initialized earlier then the EFI subsystems and all I2C/SPI ACPI devices are enumerated when the I2C/SPI controllers are initialized.

ACPI / APEI: Add Boot Error Record Table (BERT) support
ACPI/APEI is designed to verifiy/report H/W errors, like Corrected Error(CE) and Uncorrected Error(UC). It contains four tables: HEST, ERST, EINJ and BERT. The first three tables have been merged for a long time, but because of lacking BIOS support for BERT, the support for BERT is pending until now. Recently on ARM 64 platform it is has been supported. So here we come. Under normal circumstances, when a hardware error occurs, kernel will be notified via NMI, MCE or some other method, then kernel will process the error condition, report it, and recover it if possible. But sometime, the situation is so bad, so that firmware may choose to reset directly without notifying Linux kernel. Linux kernel can use the Boot Error Record Table (BERT) to get the un-notified hardware errors that occurred in a previous boot. In this patch, the error information is reported via printk. For more information about BERT, please refer to ACPI Specification version 6.0, section 18.3.1: http://www.uefi.org/sites/default/files/resources/ACPI_6.0.pdf The following log is a BERT record after system reboot because of hitting a fatal memory error: BERT: Error records from previous boot: [Hardware Error]: It has been corrected by h/w and requires no further action [Hardware Error]: event severity: corrected [Hardware Error]: Error 0, type: recoverable [Hardware Error]: section_type: memory error [Hardware Error]: error_status: 0x0000000000000400 [Hardware Error]: physical_address: 0xffffffffffffffff [Hardware Error]: card: 1 module: 2 bank: 3 row: 1 column: 2 bit_position: 5 [Hardware Error]: error_type: 2, single-bit ECC [Tomasz Nowicki: Clear error status at the end of error handling] [Tony: Applied some cleanups suggested by Fu Wei] [Fu Wei: delete EXPORT_SYMBOL_GPL(bert_disable), improve the code] Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Tomasz Nowicki <tomasz.nowicki@linaro.org> Signed-off-by: Chen, Gong <gong.chen@linux.intel.com> Tested-by: Jonathan (Zhixiong) Zhang <zjzhang@codeaurora.org> Signed-off-by: Fu Wei <fu.wei@linaro.org> Tested-by: Tyler Baicar <tbaicar@codeaurora.org> Reviewed-by: Borislav Petkov <bp@suse.de> Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Rafael J.

clocksource/drivers/arm_arch_timer: Control the evtstrm via the cmdline
Disabling the eventstream can be useful for both remotely debugging a deployed production system and development of code using WFE-based polling loops. Whilst this can currently be controlled via a Kconfig option (CONFIG_ARM_ARCH_TIMER_EVTSTREAM), it's often desirable to toggle the feature on the command line, so this patch adds a new command-line option ("clocksource.arm_arch_timer.evtstrm") to do just that. The default behaviour is determined based on CONFIG_ARM_ARCH_TIMER_EVTSTREAM.

s390/oprofile: remove hardware sampler support
Remove hardware sampler support from oprofile module. The oprofile user space utilty has been switched to use the kernel perf interface, for which we also provide hardware sampling support. In addition the hardware sampling support is also slightly broken: it supports only 16 bits for the pid and therefore would generate wrong results on machines which have a pid >64k. Also the pt_regs structure which was passed to oprofile common code cannot necessarily be used to generate sane backtraces, since the task(s) in question may run while the samples are fed to oprofile. So the result would be more or less random. However given that the only user space tools switched to the perf interface already four years ago the hardware sampler code seems to be unused code, and therefore it should be reasonable to remove it. The timer based oprofile support continues to work.

PCI: Extending pci=resource_alignment to specify device/vendor IDs
Some uio-based PCI drivers, e.g., uio_cif do not work if the assigned PCI memory resources are not page aligned. By using the kernel option "pci=resource_alignment" it is possible to force single PCI boards to use page alignment for their memory resources. However, this is fairly cumbersome if several of these boards are in use as the specification of the cards has to be done via PCI bus/slot/function number which might change, e.g., by adding another board. Extend the kernel option "pci=resource_alignment" to allow specification of relevant devices via PCI device/vendor (and subdevice/subvendor) IDs. The specification of the devices via device/vendor is indicated by a leading string "pci:" as argument to "pci=resource_alignment". The format of the specification is pci:<vendor>:<device>[:<subvendor>:<subdevice>] Signed-off-by: Mathias Koehrer <mathias.koehrer@etas.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> |

PCI: Put PCIe ports into D3 during suspend
Currently the Linux PCI core does not touch power state of PCI bridges and PCIe ports when system suspend is entered. Leaving them in D0 consumes power unnecessarily and may prevent the CPU from entering deeper C-states. With recent PCIe hardware we can power down the ports to save power given that we take into account few restrictions: - The PCIe port hardware is recent enough, starting from 2015. - Devices connected to PCIe ports are effectively in D3cold once the port is transitioned to D3 (the config space is not accessible anymore and the link may be powered down). - Devices behind the PCIe port need to be allowed to transition to D3cold and back. There is a way both drivers and userspace can forbid this. - If the device behind the PCIe port is capable of waking the system it needs to be able to do so from D3cold. This patch adds a new flag to struct pci_device called 'bridge_d3'. This flag is set and cleared by the PCI core whenever there is a change in power management state of any of the devices behind the PCIe port. When system later on is suspended we only need to check this flag and if it is true transition the port to D3 otherwise we leave it in D0. Also provide override mechanism via command line parameter "pcie_port_pm=[off|force]" that can be used to disable or enable the feature regardless of the BIOS manufacturing date.

To me, quite obviously, the biggest ticket item is the new "schedutil" governor. Interestingly enough, it's the first new cpufreq governor since the beginning of the git era (except for some out-of-the-tree ones). There are two main differences between it and the existing governors. First, it uses the information provided by the scheduler directly for making its decisions, so it doesn't have to track anything by itself. Second, it can invoke drivers (supporting that feature) to adjust CPU performance right away without having to spawn work items to be executed in process context or similar. Currently, the acpi-cpufreq driver is the only one supporting that mode of operation, but then it is used on a large number of systems. The "schedutil" governor as included here is very simple and mostly regarded as a foundation for future work on the integration of the scheduler with CPU power management (in fact, there is work in progress on top of it already). Nevertheless it works and the preliminary results obtained with it are encouraging. There also is some consolidation of CPU frequency management for ARM platforms that can add their machine IDs the the new stub dt-platdev driver now and that will take care of creating the requisite platform device for cpufreq-dt, so it is not necessary to do that in platform code any more. Several ARM platforms are switched over to using this generic mechanism. In addition to that, the intel_pstate driver is now going to respect CPU frequency limits set by the platform firmware (or a BMC) and provided via the ACPI _PPC object. The devfreq subsystem is getting a new "passive" governor for SoCs subsystems that will depend on somebody else to manage their voltage rails and its support for Samsung Exynos SoCs is consolidated. The rest is support for new hardware (Intel Broxton support in intel_idle for one example), bug fixes, optimizations and cleanups in a number of places.

For platforms which are controlled via remove node manager, enable _PPC by default. These platforms are mostly categorized as enterprise server or performance servers. These platforms needs to go through some certifications tests, which tests control via _PPC. The relative risk of enabling by default is low as this is is less likely that these systems have broken _PSS table.

cpufreq: intel_pstate: Enforce _PPC limits
Use ACPI _PPC notification to limit max P state driver will request. ACPI _PPC change notification is sent by BIOS to limit max P state in several cases: - Reduce impact of platform thermal condition - When Config TDP feature is used, a changed _PPC is sent to follow TDP change - Remote node managers in server want to control platform power via baseboard management controller (BMC) This change registers with ACPI processor performance lib so that _PPC changes are notified to cpufreq core, which in turns will result in call to .setpolicy() callback. Also the way _PSS table identifies a turbo frequency is not compatible to max turbo frequency in intel_pstate, so the very first entry in _PSS needs to be adjusted. This feature can be turned on by using kernel parameters: intel_pstate=support_acpi_ppc Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com> [ rjw: Minor cleanups ] Signed-off-by: Rafael J.
