2025-03-10soundwire: debugfs: add interface for BPT/BRA transfersPierre-Louis Bossart
Add code to show what codec drivers will need to do to enable BPT/BRA transfers. The only difference is to set the 'command_type' file to '1'. A zero-value will rely on regular read/write commands in Column0.

2025-03-10soundwire: bus: add send_async/wait APIs for BPT protocolPierre-Louis Bossart
Add definitions and helpers for the BPT/BRA protocol. Peripheral drivers (aka ASoC codec drivers) can use this API to send bulk data such as firmware or tables. The design intent is however NOT to directly use this API but to rely on an intermediate regmap layer. The API is only available when no other audio streams have been allocated, and only one BTP/BRA stream is allowed per link. To avoid the addition of yet another lock, the refcount tests are handled in the stream master_runtime alloc/free routines where the bus_lock is already held. Another benefit of this approach is that the same bus_lock is used to handle runtime and port linked lists, which reduces the potential for misaligned configurations. In addition to exclusion with audio streams, BPT transfers have a lot of overhead, specifically registers writes are needed to enable transport in DP0. Most DMAs don't handle too well very small data sets and they may have alignment limitations. The size and alignment requirements are for now not handled by the core but must be checked by platform-specific drivers.

2025-03-10soundwire: cadence: add BTP support for DP0Pierre-Louis Bossart
The register definitions are missing a BULK_ENABLE bitfield which must be set for DP0. In addition, the existing mapping from PDI to Data Port is 1:1. That's fine for PCM streams which are by construction in one direction only. The BTP/BRA protocol is bidirectional and relies on DP0 only, which breaks the 1:1 mapping. DP0 MUST be mapped to both PDI0 and PDI1, with PDI0 taking care of the TX direction and PDI1 of the RX direction.

Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4.

2025-01-31block: force noio scope in blk_mq_freeze_queueChristoph Hellwig
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.

git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux Pull more s390 updates from Alexander Gordeev: - The rework that uncoupled physical and virtual address spaces inadvertently prevented KASAN shadow mappings from using large pages. 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.

2025-01-29Bluetooth: btnxpuart: Fix glitches seen in dual A2DP streamingNeeraj Sanjay Kale
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.
