2025-02-19spi: s3c64xx: extend description of compatible's fifo_depthTudor Ambarus
The FIFO depth specified with the compatibles's data is used where all the instances of the IP define the same FIFO depth. It naturally has higher precedence than the FIFO depth specified via DT. Specifying FIFO depth in DT becomes superfluous in this case. Extend comment about compatible's FIFO depth.

2025-02-10spi: axi-spi-engine: add offload supportMark Brown
Merge series from David Lechner <dlechner@baylibre.com>: As a recap, here is the background and end goal of this series: The AXI SPI Engine is a SPI controller that has the ability to record a series of SPI transactions and then play them back using a hardware trigger. This allows operations to be performed, repeating many times, without any CPU intervention. This is needed for achieving high data rates (millions of samples per second) from ADCs and DACs that are connected via a SPI bus. The offload hardware interface consists of a trigger input and a data output for the RX data. These are connected to other hardware external to the SPI controller. To record one or more transactions, commands and TX data are written to memories in the controller (RX buffer is not used since RX data gets streamed to an external sink). This sequence of transactions can then be played back when the trigger input is asserted. This series includes core SPI support along with the first SPI controller (AXI SPI Engine) and SPI peripheral (AD7944 ADC) that use them. This enables capturing analog data at 2 million samples per second. The hardware setup looks like this: +-------------------------------+ +------------------+ | | | | | SOC/FPGA | | AD7944 ADC | | +---------------------+ | | | | | AXI SPI Engine | | | | | | SPI Bus ============ SPI Bus | | | | | | | | | +---------------+ | | | | | | | Offload 0 | | | +------------------+ | | | RX DATA OUT > > > > | | | | TRIGGER IN < < < v | | | +---------------+ | ^ v | | +---------------------+ ^ v | | | AXI PWM | ^ v | | | CH0 > ^ v | | +---------------------+ v | | | AXI DMA | v | | | CH0 < < < | | +---------------------+ | | | +-------------------------------+
2025-02-07spi: axi-spi-engine: implement offload supportDavid Lechner
Implement SPI offload support for the AXI SPI Engine. Currently, the hardware only supports triggering offload transfers with a hardware trigger so attempting to use an offload message in the regular SPI message queue will fail. Also, only allows streaming rx data to an external sink, so attempts to use a rx_buf in the offload message will fail.

2025-02-07spi: add offload TX/RX streaming APIsDavid Lechner
Most configuration of SPI offloads is handled opaquely using the offload pointer that is passed to the various offload functions. However, there are some offload features that need to be controlled on a per transfer basis. This patch adds a flag field to struct spi_transfer to allow specifying such features. The first feature to be added is the ability to stream data to/from a hardware sink/source rather than using a tx or rx buffer. Additional flags can be added in the future as needed. A flags field is also added to the offload struct for providers to indicate which flags are supported. This allows for generic checking of offload capabilities during __spi_validate() so that each offload provider doesn't have to implement their own validation. As a first users of this streaming capability, getter functions are added to get a DMA channel that is directly connected to the offload. Peripheral drivers will use this to get a DMA channel and configure it to suit their needs.

2025-02-07spi: offload: add support for hardware triggersDavid Lechner
Extend SPI offloading to support hardware triggers. This allows an arbitrary hardware trigger to be used to start a SPI transfer that was previously set up with spi_optimize_message(). A new struct spi_offload_trigger is introduced that can be used to configure any type of trigger. It has a type discriminator and a union to allow it to be extended in the future. Two trigger types are defined to start with. One is a trigger that indicates that the SPI peripheral is ready to read or write data. The other is a periodic trigger to repeat a SPI message at a fixed rate. There is also a spi_offload_hw_trigger_validate() function that works similar to clk_round_rate(). It basically asks the question of if we enabled the hardware trigger what would the actual parameters be. This can be used to test if the requested trigger type is actually supported by the hardware and for periodic triggers, it can be used to find the actual rate that the hardware is capable of.

2025-02-07spi: add basic support for SPI offloadingDavid Lechner
Add the basic infrastructure to support SPI offload providers and consumers. SPI offloading is a feature that allows the SPI controller to perform transfers without any CPU intervention. This is useful, e.g. for high-speed data acquisition. SPI controllers with offload support need to implement the get_offload and put_offload callbacks and can use the devm_spi_offload_alloc() to allocate offload instances. SPI peripheral drivers will call devm_spi_offload_get() to get a reference to the matching offload instance. This offload instance can then be attached to a SPI message to request offloading that message. It is expected that SPI controllers with offload support will check for the offload instance in the SPI message in the ctlr->optimize_message() callback and handle it accordingly. CONFIG_SPI_OFFLOAD is intended to be a select-only option. Both consumer and provider drivers should `select SPI_OFFLOAD` in their Kconfig to ensure that the SPI core is built with offload support.

When block drivers or the core block code perform allocations with a frozen queue, this could try to recurse into the block device to reclaim memory and deadlock. Thus all allocations done by a process that froze a queue need to be done without __GFP_IO and __GFP_FS. Instead of tying to track all of them down, force a noio scope as part of freezing the queue. Note that nvme is a bit of a mess here due to the non-owner freezes, and they will be addressed separately.

Restore large page mappings for KASAN shadows - Add decompressor routine physmem_alloc() that may fail, unlike physmem_alloc_or_die(). This allows callers to implement fallback paths - Allow falling back from large pages to smaller pages (1MB or 4KB) if the allocation of 2GB pages in the decompressor can not be fulfilled - Add to the decompressor boot print support of "%%" format string, width and padding hadnling, length modifiers and decimal conversion specifiers - Add to the decompressor message severity levels similar to kernel ones. Support command-line options that control console output verbosity - Replaces boot_printk() calls with appropriate loglevel- specific helpers such as boot_emerg(), boot_warn(), and boot_debug(). - Collect all boot messages into a ring buffer independent of the current log level. This is particularly useful for early crash analysis - If 'earlyprintk' command line parameter is not specified, store decompressor boot messages in a ring buffer to be printed later by the kernel, once the console driver is registered - Add 'bootdebug' command line parameter to enable printing of decompressor debug messages when needed. That parameters allows message suppressing and filtering - Dump boot messages on a decompressor crash, but only if 'bootdebug' command line parameter is enabled - When CONFIG_PRINTK_TIME is enabled, add timestamps to boot messages in the same format as regular printk() - Dump physical memory tracking information on boot: online ranges, reserved areas and vmem allocations - Dump virtual memory layout and randomization details - Improve decompression error reporting and dump the message ring buffer in case the boot failed and system halted - Add an exception handler which handles exceptions when FPU control register is attempted to be set to an invalid value. Remove '.fixup' section as result of this change - Use 'A', 'O', and 'R' inline assembly format flags, which allows recent Clang compilers to generate better FPU code - Rework uaccess code so it reads better and generates more efficient code - Cleanup futex inline assembly code - Disable KMSAN instrumention for futex inline assemblies, which contain dereferenced user pointers. Otherwise, shadows for the user pointers would be accessed - PFs which are not initially configured but in standby create only a single-function PCI domain. If they are configured later on, sibling PFs and their child VFs will not be added to their PCI domain breaking SR-IOV expectations. Fix that by allowing initially configured but in standby PFs create multi-function PCI domains - Add '-std=gnu11' to decompressor and purgatory CFLAGS to avoid compile errors caused by kernel's own definitions of 'bool', 'false', and 'true' conflicting with the C23 reserved keywords - Fix sclp subsystem failure when a sclp console is not present - Fix misuse of non-NULL terminated strings in vmlogrdr driver - Various other small improvements, cleanups and fixes * tag 's390-6.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (53 commits) s390/vmlogrdr: Use array instead of string initializer s390/vmlogrdr: Use internal_name for error messages s390/sclp: Initialize sclp subsystem via arch_cpu_finalize_init() s390/tools: Use array instead of string initializer s390/vmem: Fix null-pointer-arithmetic warning in vmem_map_init() s390: Add '-std=gnu11' to decompressor and purgatory CFLAGS s390/bitops: Use correct constraint for arch_test_bit() inline assembly s390/pci: Fix SR-IOV for PFs initially in standby s390/futex: Avoid KMSAN instrumention for user pointers s390/uaccess: Rename get_put_user_noinstr_attributes to uaccess_kmsan_or_inline s390/futex: Cleanup futex_atomic_cmpxchg_inatomic() s390/futex: Generate futex atomic op functions s390/uaccess: Remove INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER s390/uaccess: Use asm goto for put_user()/get_user() s390/uaccess: Remove usage of the oac specifier s390/uaccess: Replace EX_TABLE_UA_LOAD_MEM exception handling s390/uaccess: Cleanup noinstr __put_user()/__get_user() inline assembly constraints s390/uaccess: Remove __put_user_fn()/__get_user_fn() wrappers s390/uaccess: Move put_user() / __put_user() close to put_user() asm code s390/uaccess: Use asm goto for __mvc_kernel_nofault() ...

2025-01-29bgmac: reduce max frame size to support just MTU 1500Rafał Miłecki
bgmac allocates new replacement buffer before handling each received frame. Allocating & DMA-preparing 9724 B each time consumes a lot of CPU time. Ideally bgmac should just respect currently set MTU but it isn't the case right now. For now just revert back to the old limited frame size. This change bumps NAT masquerade speed by ~95%. Since commit 8218f62c9c9b ("mm: page_frag: use initial zero offset for page_frag_alloc_align()"), the bgmac driver fails to open its network interface successfully and runs out of memory in the following call stack: bgmac_open -> bgmac_dma_init -> bgmac_dma_rx_skb_for_slot -> netdev_alloc_frag BGMAC_RX_ALLOC_SIZE = 10048 and PAGE_FRAG_CACHE_MAX_SIZE = 32768. Eventually we land into __page_frag_alloc_align() with the following parameters across multiple successive calls: __page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=0 __page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=10048 __page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=20096 __page_frag_alloc_align: fragsz=10048, align_mask=-1, size=32768, offset=30144 So in that case we do indeed have offset + fragsz (40192) > size (32768) and so we would eventually return NULL. Reverting to the older 1500 bytes MTU allows the network driver to be usable again.

This fixes a regression caused by previous commit for fixing truncated ACL data, which is causing some intermittent glitches when running two A2DP streams. serdev_device_write_buf() is the root cause of the glitch, which is reverted, and the TX work will continue to write until the queue is empty. This change fixes both issues. No A2DP streaming glitches or truncated ACL data issue observed.
