2021-07-21docs: driver-api: fpga: avoid using UTF-8 charsMauro Carvalho Chehab
While UTF-8 characters can be used at the Linux documentation, the best is to use them only when ASCII doesn't offer a good replacement. So, replace the occurences of the following UTF-8 characters: - U+2014 ('—'): EM DASH Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org> Signed-off-by: Moritz Fischer <mdf@kernel.org>
2021-07-21docs: gpio: explain GPIOD_OUT_* values and toggling active lowHannu Hartikainen
I was confused about the gpiod_flags values and thought that GPIOD_OUT_LOW and GPIOD_OUT_HIGH set the line to be active low / active high. This is not true, but I got the misconception because the flags GPIOD_OUT_*_OPEN_DRAIN do change line configuration and there's a subchapter about *active low* and *open drain* semantics. Add an explicit mention that the initial value is a logical value (and not the line configuration or physical line level). Also add a mention of the function gpiod_toggle_active_low which was previously missing from this document.

2021-07-21Documentation: gpio: driver.rst: Remove gpiochip_irqchip_add mentionVincent Pelletier
This function was removed in commit f1f37abbe6fc ("gpio: Retire the explicit gpio irqchip code") but this mention was left behind. Also, mention that .set_type() only has to set a line handler if the chip is cascaded, as opposed to hierarchical.

git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl Pull CXL (Compute Express Link) updates from Dan Williams: "This subsystem is still in the build-out phase as the bulk of the update is improvements to enumeration and fleshing out the device model. In terms of new features, more mailbox commands have been added to the allowed-list in support of persistent memory provisioning support targeting v5.15. The critical update from an enumeration perspective is support for the CXL Fixed Memory Window Structure that indicates to Linux which system physical address ranges decode to the CXL Host Bridges in the system. This allows the driver to detect which address ranges have been mapped by firmware and what address ranges are available for future hotplug. So, again, mostly skeleton this round, with more meat targeting v5.15. Summary: - Add support for the CXL Fixed Memory Window Structure, a recent extension of the ACPI CEDT (CXL Early Discovery Table) - Add infrastructure for component registers - Add HDM (Host-managed device memory) decoder definitions - Define a device model for an HDM decoder tree - Bridge CXL persistent memory capabilities to an NVDIMM bus / device-model - Switch to fine grained mapping of CXL MMIO registers to allow different drivers / system software to own individual register blocks - Enable media provisioning commands, and publish the label storage area size in sysfs - Miscellaneous cleanups and fixes" * tag 'cxl-for-5.14' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl: (34 commits) cxl/pci: Rename CXL REGLOC ID cxl/acpi: Use the ACPI CFMWS to create static decoder objects cxl/acpi: Add the Host Bridge base address to CXL port objects cxl/pmem: Register 'pmem' / cxl_nvdimm devices libnvdimm: Drop unused device power management support libnvdimm: Export nvdimm shutdown helper, nvdimm_delete() cxl/pmem: Add initial infrastructure for pmem support cxl/core: Add cxl-bus driver infrastructure cxl/pci: Add media provisioning required commands cxl/component_regs: Fix offset cxl/hdm: Fix decoder count calculation cxl/acpi: Introduce cxl_decoder objects cxl/acpi: Enumerate host bridge root ports cxl/acpi: Add downstream port data to cxl_port instances cxl/Kconfig: Default drivers to CONFIG_CXL_BUS cxl/acpi: Introduce the root of a cxl_port topology cxl/pci: Fixup devm_cxl_iomap_block() to take a 'struct device *' cxl/pci: Add HDM decoder capabilities cxl/pci: Reserve individual register block regions cxl/pci: Map registers based on capabilities ...

2021-06-15dmabuf: Add the capability to expose DMA-BUF stats in sysfsHridya Valsaraju
Overview ======== The patch adds DMA-BUF statistics to /sys/kernel/dmabuf/buffers. It allows statistics to be enabled for each DMA-BUF in sysfs by enabling the config CONFIG_DMABUF_SYSFS_STATS. The following stats will be exposed by the interface: /sys/kernel/dmabuf/buffers/<inode_number>/exporter_name /sys/kernel/dmabuf/buffers/<inode_number>/size /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/device /sys/kernel/dmabuf/buffers/<inode_number>/attachments/<attach_uid>/map_counter The inode_number is unique for each DMA-BUF and was added earlier [1] in order to allow userspace to track DMA-BUF usage across different processes. Use Cases ========= The interface provides a way to gather DMA-BUF per-buffer statistics from production devices. These statistics will be used to derive DMA-BUF per-exporter stats and per-device usage stats for Android Bug reports. The corresponding userspace changes can be found at [2]. Telemetry tools will also capture this information(along with other memory metrics) periodically as well as on important events like a foreground app kill (which might have been triggered by Low Memory Killer). It will also contribute to provide a snapshot of the system memory usage on other events such as OOM kills and Application Not Responding events. Background ========== Currently, there are two existing interfaces that provide information about DMA-BUFs. 1) /sys/kernel/debug/dma_buf/bufinfo debugfs is however unsuitable to be mounted in production systems and cannot be considered as an alternative to the sysfs interface being proposed. 2) proc/<pid>/fdinfo/<fd> The proc/<pid>/fdinfo/<fd> files expose information about DMA-BUF fds. However, the existing procfs interfaces can only provide information about the buffers for which processes hold fds or have the buffers mmapped into their address space. Since the procfs interfaces alone cannot provide a full picture of all DMA-BUFs in the system, there is the need for an alternate interface to provide this information on production systems. The patch contains the following major improvements over v1: 1) Each attachment is represented by its own directory to allow creating a symlink to the importing device and to also provide room for future expansion. 2) The number of distinct mappings of each attachment is exposed in a separate file. 3) The per-buffer statistics are now in /sys/kernel/dmabuf/buffers inorder to make the interface expandable in future. All of the improvements above are based on suggestions/feedback from Daniel Vetter and Christian König. A shell script that can be run on a classic Linux environment to read out the DMA-BUF statistics can be found at [3](suggested by John Stultz).

2021-06-09cxl/acpi: Introduce the root of a cxl_port topologyDan Williams
While CXL builds upon the PCI software model for enumeration and endpoint control, a static platform component is required to bootstrap the CXL memory layout. Similar to how ACPI identifies root-level PCI memory resources, ACPI data enumerates the address space and interleave configuration for CXL Memory. In addition to identifying host bridges, ACPI is responsible for enumerating the CXL memory space that can be addressed by downstream decoders. This is similar to the requirement for ACPI to publish resources via the _CRS method for PCI host bridges. Specifically, ACPI publishes a table, CXL Early Discovery Table (CEDT), which includes a list of CXL Memory resources, CXL Fixed Memory Window Structures (CFMWS). For now, introduce the core infrastructure for a cxl_port hierarchy starting with a root level anchor represented by the ACPI0017 device. Follow on changes model support for the configurable decode capabilities of cxl_port instances, i.e. CXL switch support.

2021-06-04pwm: core: Support new usage_power setting in PWM stateClemens Gruber
If usage_power is set, the PWM driver is only required to maintain the power output but has more freedom regarding signal form. If supported, the signal can be optimized, for example to improve EMI by phase shifting individual channels.
