Pull drm updates from Dave Airlie: "This contains two major new drivers: - imagination is a first driver for Imagination Technologies devices, it only covers very specific devices, but there is hope to grow it - xe is a reboot of the i915 GPU (shares display) side using a more upstream focused development model, and trying to maximise code sharing. It's not enabled for any hw by default, and will hopefully get switched on for Intel's Lunarlake. This also drops a bunch of the old UMS ioctls. It's been dead long enough. amdgpu has a bunch of new color management code that is being used in the Steam Deck. amdgpu also has a new ACPI WBRF interaction to help avoid radio interference. Otherwise it's the usual lots of changes in lots of places.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management updates from Rafael Wysocki: "These add support for new processors (Sierra Forest, Grand Ridge and Meteor Lake) to the intel_idle driver, make intel_pstate run on Emerald Rapids without HWP support and adjust it to utilize EPP values supplied by the platform firmware, fix issues, clean up code and improve documentation. The most significant fix addresses deadlocks in the core system-wide resume code that occur if async_schedule_dev() attempts to run its argument function synchronously (for example, due to a memory allocation failure). It rearranges the code in question which may increase the system resume time in some cases, but this basically is a removal of a premature optimization. That optimization will be added back later, but properly this time.

2023-12-29crypto: qat - add support for device telemetryLucas Segarra Fernandez1-0/+103
Expose through debugfs device telemetry data for QAT GEN4 devices. This allows to gather metrics about the performance and the utilization of a device. In particular, statistics on (1) the utilization of the PCIe channel, (2) address translation, when SVA is enabled and (3) the internal engines for crypto and data compression. If telemetry is supported by the firmware, the driver allocates a DMA region and a circular buffer. When telemetry is enabled, through the `control` attribute in debugfs, the driver sends to the firmware, via the admin interface, the `TL_START` command. This triggers the device to periodically gather telemetry data from hardware registers and write it into the DMA memory region. The device writes into the shared region every second. The driver, every 500ms, snapshots the DMA shared region into the circular buffer. This is then used to compute basic metric (min/max/average) on each counter, every time the `device_data` attribute is queried. Telemetry counters are exposed through debugfs in the folder /sys/kernel/debug/qat_<device>_<BDF>/telemetry. For details, refer to debugfs-driver-qat_telemetry in Documentation/ABI.

2023-12-22cxl: Export sysfs attributes for memory device QoS classDave Jiang1-0/+34
Export qos_class sysfs attributes for the CXL memory device. The QoS clas should show up as /sys/bus/cxl/devices/memX/ram/qos_class for the volatile partition and /sys/bus/cxl/devices/memX/pmem/qos_class for the persistent partition. The QTG ID is retrieved via _DSM after supplying the calculated bandwidth and latency for the entire CXL path from device to the CPU. This ID is used to match up to the root decoder QoS class to determine which CFMWS the memory range of a hotplugged CXL mem device should be assigned under. While there may be multiple DSMAS exported by the device CDAT, the driver will only expose the first QTG ID per partition in sysfs for now. In the future when multiple QTG IDs are necessary, they can be exposed.

2023-12-19accel/habanalabs: add parent_device sysfs attributeTomer Tayar1-0/+6
The device debugfs directory was modified to be named as the device-name. This name is the parent device name, i.e. either the PCI address in case of an ASIC, or the simulator device name in case of a simulator. This change makes it more difficult for a user to access the debugfs directory for a specific accel device, because he can't just use the accel minor id, but he needs to do more device-dependent operations to get the device name. To make it easier to get this name, add a 'parent_device' sysfs attribute that the user can read using the minor id before accessing debugfs.

2023-12-15initramfs: Expose retained initrd as sysfs fileAlexander Graf1-0/+8
When the kernel command line option "retain_initrd" is set, we do not free the initrd memory. However, we also don't expose it to anyone for consumption. That leaves us in a weird situation where the only user of this feature is ppc64 and arm64 specific kexec tooling. To make it more generally useful, this patch adds a kobject to the firmware object that contains the initrd context when "retain_initrd" is set. That way, we can access the initrd any time after boot from user space and for example hand it into kexec as --initrd parameter if we want to reboot the same initrd. Or inspect it directly locally. With this patch applied, there is a new /sys/firmware/initrd file when the kernel was booted with an initrd and "retain_initrd" command line option is set.

The binary content of nvmem devices is available to the user so in the easiest cases, finding the content of a cell is rather easy as it is just a matter of looking at a known and fixed offset. However, nvmem layouts have been recently introduced to cope with more advanced situations, where the offset and size of the cells is not known in advance or is dynamic. When using layouts, more advanced parsers are used by the kernel in order to give direct access to the content of each cell regardless of their position/size in the underlying device, but these information were not accessible to the user. By exposing the nvmem cells to the user through a dedicated cell/ folder containing one file per cell, we provide a straightforward access to useful user information without the need for re-writing a userland parser. Content of nvmem cells is usually: product names, manufacturing date, MAC addresses, etc, Signed-off-by: Miquel Raynal <[email protected]> Reviewed-by: Greg Kroah-Hartman <[email protected]> Signed-off-by: Srinivas Kandagatla <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
2023-12-13Merge patch series "Add UFS RTC support"Martin K. Petersen1-0/+7
Bean Huo <[email protected]> says: Adding RTC support for embedded storage device UFS in its driver, it is important for a few key reasons: 1. Helps with Regular Maintenance: The RTC provides a basic way to keep track of time, making it useful for scheduling routine maintenance tasks in the storage device. This includes things like making sure data is spread evenly across the storage to extend its life. 2. Figuring Out How Old Data Is: The RTC helps the device estimate how long ago certain parts of the storage were last used. This is handy for deciding when to do maintenance tasks to keep the storage working well over time. 3. Making Devices Last Longer: By using the RTC for regular upkeep, we can make sure the storage device lasts longer and stays reliable. This is especially important for devices that need to work well for a long time. 4.Fitting In with Other Devices: The inclusion of RTC support aligns with existing UFS specifications (starting from UFS Spec 2.0) and is consistent with the prevalent industry practice. Many UFS devices currently on the market utilize RTC for internal timekeeping. By ensuring compatibility with this widely adopted standard, the embedded storage device becomes seamlessly integrable with existing hardware and software ecosystems, reducing the risk of compatibility issues. In short, adding RTC support to embedded storage device UFS helps with regular upkeep, extends the device's life, ensures compatibility, and keeps everything running smoothly with the rest of the system.

2023-12-13leds: ledtrig-tty: Add additional line state evaluationFlorian Eckert1-0/+40
The serial tty interface also supports additional input signals, that can also be evaluated within this trigger. This change is adding the following additional input sources, which could be controlled via the '/sys/class/<leds>/' sysfs interface. Explanation: DCE = Data Communication Equipment (Modem) DTE = Data Terminal Equipment (Computer) - cts: DCE is ready to accept data from the DTE (CTS = Clear To Send). If the line state is detected, the LED is switched on. If set to 0 (default), the LED will not evaluate CTS. If set to 1, the LED will evaluate CTS. - dsr: DCE is ready to receive and send data (DSR = Data Set Ready). If the line state is detected, the LED is switched on. If set to 0 (default), the LED will not evaluate DSR. If set to 1, the LED will evaluate DSR. - dcd: DTE is receiving a carrier from the DCE (DCD = Data Carrier Detect). If the line state is detected, the LED is switched on. If set to 0 (default), the LED will not evaluate DCD. If set to 1, the LED will evaluate DCD. - rng: DCE has detected an incoming ring signal on the telephone line (RNG = Ring Indicator). If the line state is detected, the LED is switched on. If set to 0 (default), the LED will not evaluate RNG. If set to 1, the LED will evaluate RNG. Also add an invert flag on LED blink, so that the LED blinks in the correct order. * If one off the new enabled input signals are evaluatet as 'enabled', and data are transmitted, then the LED should first blink 'off' and then 'on' (invert). * If all the new enabled input signals are evaluatet as 'disabled', and data are transmitted, then the LED should first blink 'on' and then 'off'.

2023-12-13leds: ledtrig-tty: Make rx tx activitate configurableFlorian Eckert1-0/+16
Until now, the LED blinks when data is sent via the tty (rx/tx). This is not configurable. This change adds the possibility to make the indication for the direction of the transmitted data independently controllable via the new rx and tx sysfs entries. - rx: Signal reception (rx) of data on the named tty device. If set to 0, the LED will not blink on reception. If set to 1 (default), the LED will blink on reception. - tx: Signal transmission (tx) of data on the named tty device. If set to 0, the LED will not blink on transmission. If set to 1 (default), the LED will blink on transmission. This new sysfs entry are on by default. Thus the trigger behaves as before this change.
